Referring to FIGS. 4A, 4B, 5, and 6, a speaker module 200 according to an embodiment may include an air conduction speaker 210 and a bone conduction speaker 230 sharing the yoke plate 250. The speaker module 200 may be disposed at a specified position of a support (e.g., the support 380 of FIGS. 3A and 3B) of the electronic device 101 extending in the front and rear directions to surround or at least partially surround the user's head.
In an embodiment, the yoke plate 250 may be shared by the air conduction speaker 210 and the bone conduction speaker 230, and may partition the inner space of the air conduction speaker 210 while simultaneously partitioning the inner space of the bone conduction speaker 230. In an embodiment, the yoke plate 250 may be disposed inward of the support 380 to be positioned adjacent to the skin of the user wearing the electronic device 101.
In an embodiment, the yoke plate 250 may serve as a vibrator that fixes the first magnet 211 of the air conduction speaker 210 while contacting the user of the speaker module 200. In an embodiment, the air conduction speaker 210 may emit sound in one direction of the yoke plate 250 through the diaphragm 215 disposed to be spaced apart from the yoke plate 250 in one direction, and the bone conduction speaker 230 may contact the user's skin through the other side surface of the yoke plate 250 to transfer vibration.
In an embodiment, the air conduction speaker 210 may include a first magnet 211 fixed to the yoke plate 250, a diaphragm 215 disposed to be spaced apart from the yoke plate 250, and/or a first coil 213 fixed to the diaphragm 215.
In an embodiment, the first magnet 211 may be positioned on one side surface of the yoke plate 250 and may be fixedly coupled to the yoke plate 250. For example, the first magnet 211 may be fixed to the yoke plate 250 by a fixing plate 217 spaced apart from the yoke plate 250 in one direction to prevent the first magnet 211 from moving.
In an embodiment, the diaphragm 215 may be spaced apart from the yoke plate 250 in one direction to partition the inner space of the air conduction speaker 210, and the first magnet 211 and/or the first coil 213 may be disposed in the inner space. For example, the diaphragm 215 may be coupled to the column 219 coupled to the fixing plate 217 and may be supported in a state of being spaced apart from the yoke plate 250 and the first magnet 211 in one direction.
In the embodiment illustrated in FIG. 4A, the diaphragm 215 may have a hollow shape having a passed-through central portion, an outer end thereof may be coupled to the column 219, and an inner end thereof may be coupled to a housing 235 of the bone conduction speaker 230 to be described below.
In an embodiment illustrated in FIG. 4B, the diaphragm 215 may extend in a planar direction, and an outer end thereof may be coupled to the column 219. In an embodiment, the diaphragm 215 may extend inward to cover or at least partially cover the upper portion of the housing 235 of the bone conduction speaker 230. For example, the upper portion of the housing 235 may be completely covered such that the housing 235 of the bone conduction speaker 230 is not exposed to the outside.
In an embodiment, the housing 235 may be formed of a metal-based material (e.g., the housing 235 may include a metal-based material) to easily transfer the vibration of the diaphragm 215 to the yoke plate 250.
In an embodiment, the diaphragm 215 may be disposed to be spaced apart from the yoke plate 250 and may be disposed to at least partially face the yoke plate 250 to linearly reciprocate in a direction toward or away from the yoke plate 250.
In an embodiment, the first magnet 211 may be disposed on the yoke plate 250, the first coil 213 may be disposed on the diaphragm 215, and the first magnet 211 and the first coil 213 may be positioned to be deviated from each other in a direction in which the yoke plate 250 and the diaphragm 215 are spaced apart from each other such that a position deviation occurs at least partially.
In an embodiment, the first coil 213 may be fixedly coupled to the diaphragm 215, and the diaphragm 215 may generate vibration by moving the first coil 213. In an embodiment, the first coil 213 may cause a movement along one direction of the yoke plate 250 by the magnetic field generated by the first magnet 211 and a change in current in the first coil 213, vibrating the diaphragm 215 fixedly coupled and hence emitting sound (e.g., sound or voice) in the air.
In an embodiment, the bone conduction speaker 230 may include a housing 235 coupled to the yoke plate 250 on a side of the air conduction speaker 210, a second coil 233 positioned in the housing 235 and fixed to the yoke plate 250, and a second magnet 231 positioned to be spaced apart from the second coil 233 in the housing 235 and coupled to the housing 235.
In an embodiment, the bone conduction speaker 230 may be formed on one side of the yoke plate 250 and may be disposed on the side of the air conduction speaker 210. For example, the yoke plate 250 may simultaneously partition the air conduction speaker 210 and the bone conduction speaker 230. In an embodiment, the second coil 233 and/or the second magnet 231 may be disposed in a space partitioned between the yoke plate 250 and the housing 235.
In an embodiment, the housing 235 may include a side surface extending in one direction from the yoke plate 250 and one surface extending in a planar direction from an end portion of the side surface. In an embodiment, the housing 235 may be formed of a metal material, and one surface thereof may be connected to an end portion of the diaphragm 215, and an end portion of the side surface thereof may be connected to the yoke plate 250 to transmit vibration of the diaphragm 215 to the yoke plate 250.
In an embodiment, the air conduction speaker 210 and the bone conduction speaker 230 may be positioned in one direction of the yoke plate 250, and at least portions of the air conduction speaker 210 and the bone conduction speaker 230 may overlap in the one direction of the yoke plate 250. Accordingly, the space in which the air conduction speaker 210 and the bone conduction speaker 230 are disposed may be reduced, and the difference between their relative positions may be removed, thereby removing the acoustic effect according to the position difference.
In an embodiment, the bone conduction speaker 230 may be positioned in a central portion of the yoke plate 250, and the air conduction speaker 210 may have a shape surrounding or at least partially surrounding the bone conduction speaker 230 from the outside. In an embodiment, the bone conduction speaker 230 in which the inner space is partitioned by the housing 235 may be shaped to have sides surrounded or at least partially surrounded by the first magnet 211 and/or the first coil 213 and to have one side surrounded or at least partially surrounded by the diaphragm 215.
In an embodiment, the housing 235, the second coil 233, and/or the second magnet 231 partitioning the inner space of the bone conduction speaker 230 may have a ring-shaped cross section, and the cross section of the first magnet 211, the first coil 213, and/or the diaphragm 215 of the air conduction speaker 210 may have a ring shape surrounding or at least partially surrounding the housing 235, the second coil 233, and/or the second magnet 231 of the bone conduction speaker 230 from the outside. In an embodiment, the cross sections of the first magnet 211, the first coil 213, and/or the diaphragm 215 of the air conduction speaker 210 may be concentric with the housing 235, the second coil 233, and/or the second magnet 231 of the bone conduction speaker 230.
In an embodiment, the second coil 233 may be fixedly coupled to the yoke plate 250 on one side of the yoke plate 250. The second coil 233 may vibrate due to a change in current in the second coil 233 and the magnetic field of the second magnet 231.
In an embodiment, the second magnet 231 may be coupled to the housing 235, and the second magnet 231 may be coupled to the housing 235 to be movable relative to the housing 235. In an embodiment, the electronic device may be coupled to the housing 235 (e.g., one surface of the housing 235) through an elastically deformable connection member 237 and may thus vibrate separately from the vibration of the housing 235 or may be fixed with the vibration of the housing 235 blocked.
In an embodiment, the second magnet 231 may be formed to have a designated mass or more, or may be coupled with an additional mass 232. Accordingly, the movement and/or vibration of the second magnet 231 may be minimized.

Referring further to FIGS. 7 to 8, the air conduction speaker 210 and the bone conduction speaker 230 included in the speaker module 200 of the electronic device 101 according to an embodiment may be positioned side by side. In an embodiment, the speaker module 200 may be disposed in a support (e.g., the support 380 of FIGS. 3A and 3B) of the electronic device 101 extending in the front and rear directions to surround or at least partially surround the user's head, and the air conduction speaker 210 and the bone conduction speaker 230 may be disposed to be spaced apart from each other in the front and rear directions in which the support 380 extends. In an embodiment, the air conduction speaker 210 and the bone conduction speaker 230 may at least partially overlap in the thickness direction of the support 380. Accordingly, the space in which the air conduction speaker 210 and the bone conduction speaker 230 are disposed may be reduced.
In an embodiment, the air conduction speaker 210 may be disposed at a designated position of the support 380, and may emit the sound generated by vibration of the diaphragm 215 through a wave guide 216 extending forward or backward. In an embodiment, the wave guide 216 may be formed behind the air conduction speaker, and the bone conduction speaker 230 together with the wave guide 216 may be disposed in the rear space of the air conduction speaker, thereby reducing the arrangement space.
In an embodiment, the wave guide 216 may form a path for guiding a sound (e.g., sound or voice) generated through the diaphragm 215 in a designated direction to be emitted to the outside. In an embodiment, the sound generated from the air conduction speaker 210 may be emitted outward of the user wearing the electronic device 101 through the wave guide 216.
In an embodiment, the bone conduction speaker 230 may be disposed in the front or rear of the air conduction speaker 210 in the front and rear directions in which the support 380 extends.

In an embodiment, the yoke plate 250 may be directly coupled to the support 380 or may be fixedly coupled to the support 380 through a first sound absorbing material 381. In an embodiment, the diaphragm 215 may have an outer end fixedly coupled to the column 219, and may be supported in a state of being spaced apart from the yoke plate 250 by the fixing plate 217 and/or the column 219.
In an embodiment, the first magnet 211 may be fixedly coupled to the yoke plate 250 and may be inserted into a space partitioned between the yoke plate 250 and the fixing plate 217. Thus, the first magnet 211 may be supported by the yoke plate 250 and the fixing plate 217 to prevent movement.
In an embodiment, the first coil 213 may be fixedly coupled to the diaphragm 215, and may be disposed to at least partially overlap the first magnet 211 or to be at least partially spaced apart from the first magnet 211.
In an embodiment, the bone conduction speaker 230 may include a housing 235 fixed to the support 380, a second magnet 231 coupled to the housing 235 through an elastically deformable connection member 237 inside the housing 235, a contact surface 239 contacting the user's skin, and/or a second coil 233 fixed to the contact surface 239.

In an embodiment, the housing 235 may be shaped to be open to one side while partitioning the inner space, and the open side may be covered or at least partially covered by the contact surface 239. In an embodiment, the contact surface 239 may be formed of a soft material to reduce the impedance difference from the user's skin, and may be formed of, for example, rubber or flexible plastic.

The second coil 233 may be fixedly coupled to the contact surface 239, and may transfer vibration generated by a change in internal current and a magnetic field of the second magnet 231 to the contact surface 239.
FIG. 9 is a diagram illustrating an operation of an electronic device according to an embodiment of the disclosure.
Referring to FIG. 9, an electronic device (e.g., the electronic device 101 and/or the processor 120 of FIG. 2) may operate the air conduction speaker 210 to generate a sound corresponding to a first sound range. Further, the electronic device may operate the bone conduction speaker 230 to generate vibration corresponding to a second sound range, which is at least partially lower than the first sound range.
In an embodiment, the electronic device may obtain an audio signal 900 from the outside. For example, the electronic device may obtain the audio signal 900 through an input module (e.g., the input module 150 of FIG. 1) or a microphone (e.g., the microphone 360 of FIG. 3). Alternatively, the electronic device may obtain the audio signal 900 from the outside through an interface (e.g., the interface 177 of FIG. 1) or a communication module (e.g., the communication module 190 of FIG. 1).
In an embodiment, the electronic device may control the air conduction speaker 210 to generate a sound corresponding to the first sound range, based on the obtained audio signal 900. Further, the electronic device may control the bone conduction speaker 230 to generate a vibration corresponding to the second sound range based on the obtained audio signal 900. In an embodiment, the first range may be a sound range corresponding to an intermediate range and/or a high range of sound, and the second range may be a range corresponding to a low range of sound. Accordingly, instead of the bone conduction speaker 230 having a limitation on the sound performance of the high range, the air conduction speaker 210 may generate a high-range sound. Further, by utilizing the bone conduction speaker 230, sound interference caused by noise or sound radiation to the surrounding environment may be minimized, and thus privacy may be protected.
In an embodiment, the electronic device may configure at least one channel based on the obtained audio signal 900 and transmit the at least one channel to the air conduction speaker 210 and/or the bone conduction speaker 230, respectively, thereby generating a stereo sound effect or a surround sound effect.
In an embodiment, the electronic device may filter the obtained audio signal 900 into a first sound range and a second sound range, respectively. By passing the obtained audio signal 900 through the high pass filter 910, the electronic device may filter the obtained audio signal 900 into an audio signal of a relatively high sound range and transmit the filtered audio signal to the air conduction speaker 210. Further, by passing the obtained audio signal 900 through the low pass filter 930, the electronic device may filter the obtained audio signal 900 into an audio signal of a relatively low sound range and transmit the filtered audio signal to the bone conduction speaker 230. In an embodiment, the electronic device may amplify the filtered audio signals of the high sound range and/or the low sound range and transmit the amplified audio signals to the air conduction speaker 210 or the bone conduction speaker 230, respectively.
FIG. 10 is a diagram illustrating positions of the head H of a user wearing an electronic device and sound sources S1 and S2 generating sound according to an embodiment of the disclosure. FIG. 11 is a diagram illustrating an operation of an electronic device according to an embodiment of the disclosure.
Referring to FIGS. 10 and 11, in an embodiment, the electronic device (e.g., the electronic device 101 and/or the processor 120 of FIG. 2) may apply different head-related transfer functions (HRTFs) to the obtained audio signals 900, respectively, and may transfer the same to the air conduction speaker 210 and the bone conduction speaker 230.
In an embodiment, the sensitivity of the sound perceived by the human may be different depending on the positions (elevation, azimuth) of the sound sources S1 and S2. Humans may recognize the position of the sound source according to the sensitivity profile according to the experience. As an embodiment, humans may recognize sounds generated from sound sources S1 and S2 at different positions as different from each other.
In an embodiment, the HRTF may be defined as a transfer function of the sound transmitted from the sound sources S1 and S2 to the user's ear. The HRTF includes a characteristic in which a sound is transferred by the geometric shape from the sound source to the ear canal inlet and surface reflection characteristic, and is a factor to be considered in order to naturally reproduce the sound perceived by the user.
In an embodiment, the electronic device may generate a sound in the speaker module by applying an HRTF, thereby implementing a spatial audio function that applies such an effect as if a sound source generates a sound at a specific position.
In an embodiment, when the same sound is output from the air conduction speaker 210 and the bone conduction speaker 230, the user may recognize that the sound is output from different sound sources S1 and S2 as the positions at which the sound is input to the user are different.
For example, when the air conduction speaker 210 and the bone conduction speaker 230 are disposed at positions spaced apart from each other in the front and rear directions while the user wears the electronic device 101 on the head H, the user may recognize that the distances r1 and r2 from the sound sources S1 and S2 where the input sound (e.g., audio signal 900) is generated are different due to the separation distance between the air conduction speaker 210 and the bone conduction speaker 230. In other words, front-back confusing of the input sound (e.g., audio signal 900) input to the user may occur.
In an embodiment, the electronic device may apply the HRTF to the input sound (e.g., audio signal 900) such that the user may recognize the positions of the sound sources S1 and S2 in the front and rear directions. In an embodiment, the electronic device may process the signal by the HRTF A (front or back) 950 and the HRTF B (front or back) 970 that apply the HRTF to the input sound (e.g., audio signal 900) and may transfer the processed signal to the air conduction speaker 210 and the bone conduction speaker 230, respectively.
In an embodiment, the HRTF A 950 may apply the HRTF for the air conduction speaker 210 positioned relatively to the rear (in another embodiment, relatively to the front), amplify the corresponding signal, and transfer the amplified signal to the air conduction speaker 210.
In an embodiment, the HRTF B 970 may apply the HRTF for the bone conduction speaker 230 positioned relatively to the front (in another embodiment, relatively to the rear), amplify the corresponding signal, and transfer the amplified signal to the bone conduction speaker 230.

An embodiment of the disclosure and terms used therein are not intended to limit the technical features described in the disclosure to specific embodiments, and should be understood to include various modifications, equivalents, or substitutes of the embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order), It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
An embodiment of the disclosure may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The storage medium readable by the machine may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program products may be traded as commodities between sellers and buyers. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., Play Storer™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to an embodiment, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. Some of the plurality of entities may be separately disposed in different components. According to an embodiment, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or further, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to various embodiments, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
