Description

Electronic device including acoustic holes

[0001] An embodiment of the present disclosure relates to an electronic device comprising an acoustic hole.

[0002] Recently, electronic devices have been becoming increasingly smaller, while their functions have been becoming increasingly diverse. Consequently, electrical components embedded in electronic devices may be placed in increasingly narrow spaces from surrounding structures. To perform their functions efficiently within these narrow spaces, the size, material, and shape of these electrical components may be changed. For example, to improve the sound quality of external audio signals, methods are being explored to change the material of the connection path (e.g., acoustic hole, duct, and / or microphone duct) that leads to an acoustic module (e.g., microphone) from the external environment, or to change the size and / or shape of said connection path.

[0003] The information described above may be provided as background art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art in relation to the present disclosure.

[0004] The electronic device may include an acoustic module (e.g., a microphone) for receiving an external audio signal. For example, the acoustic module may acquire an external audio signal transmitted through an acoustic hole (e.g., a microphone hole, a microphone tube). The acoustic hole may be designed in a straight shape for receiving the external audio signal. According to one embodiment, the resonant frequency of the acoustic hole may be determined by the material, length, and / or shape of the acoustic hole. If the electronic device includes a plurality of microphones, each microphone may have a different resonant frequency.

[0005] According to one embodiment, a human voice signal may be formed based on a band of about 80 Hz to about 8 kHz (e.g., voice frequency band). For example, in order to receive the voice signal clearly, it is necessary to adjust the resonance frequency of the acoustic hole outside the voice frequency band so that a specific frequency (e.g., the resonance frequency of the acoustic hole) does not resonate in the acoustic hole and distort the sound.

[0006] According to one embodiment, the electronic device may provide an acoustic hole with a modified structure and shape such that the resonant frequency of the acoustic hole is outside the range of the voice frequency band (e.g., about 80 Hz to about 8 kHz band). The electronic device may vary the structure and shape of the acoustic hole to receive a clear voice signal.

[0007] The technical tasks intended to be accomplished in this document are not limited to those mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art to which this document belongs from the description below.

[0008] According to one embodiment, an electronic device may include a housing, an acoustic module disposed in an internal space of the housing, and an acoustic hole formed in the housing and connected to the acoustic module from the outside of the electronic device through the internal space. The acoustic hole may include a first space connected to the outside, and a second space connecting the first space and the internal space. The volume of the second space may be set to be larger than the volume of the first space.

[0009] According to one embodiment, an electronic device may include a housing, an acoustic module disposed in the internal space of the housing, and an acoustic hole formed in the housing and connected to the acoustic module from the outside of the electronic device through the internal space of the electronic device. The acoustic hole may include a first space corresponding to a first column connected to the outside, and a second space corresponding to a second column connecting the first space and the internal space. The second cross-sectional area for the second column may be set to be larger than the first cross-sectional area for the first column.

[0010] According to one embodiment, the electronic device may modify the design of an acoustic hole (e.g., a conduit) for an acoustic module to obtain a clear voice signal. The structure and shape of the acoustic hole may be modified so that an internal space is secured along the path through which an external audio signal is transmitted. For example, if an internal space is formed within the acoustic hole, the resonant frequency of the acoustic hole may increase, and the resonant frequency may fall outside the range of the voice frequency band (e.g., a band of about 80 Hz to about 8 kHz). According to one embodiment, if the resonant frequency of the acoustic hole does not fall within the range of the voice frequency band, the quality (e.g., sound quality) of the voice signal transmitted through the acoustic hole may be improved. Distortion of the voice signal may be reduced.

[0011] According to one embodiment, the electronic device can reduce distortion phenomena (e.g., distortion phenomena based on resonance frequency) of a voice signal transmitted through an acoustic hole by at least partially changing the size and shape of the acoustic hole. According to one embodiment, the quality of the voice signal transmitted through the acoustic hole can be improved while maintaining the externally visible shape of the acoustic hole (e.g., design elements, aesthetics). According to one embodiment, a waterproof effect and / or dustproof effect for the acoustic hole can also be maintained.

[0012] The effects obtainable from the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present disclosure belongs from the description below.

The communication module (190) may include one or more communication processors (CP) that operate independently of a processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (194) (e.g., LAN (local area network) communication module, or power line communication module). The corresponding communication module among these communication modules can communicate with an external electronic device (104) through a first network (198) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (199) (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can identify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module (196).

[0052] The electronic device (200) of FIGS. 2a and 2b may be at least partially similar to the electronic device (101) of FIG. 1, or may include various embodiments of the electronic device.

[0053] Referring to FIG. 2a and FIG. 2b, an electronic device (200) according to one embodiment may include a housing (210) comprising a first surface (or front) (210A), a second surface (or rear) (210B), and a side (210C) surrounding the space between the first surface (210A) and the second surface (210B). In one embodiment (not shown), the housing (210) may refer to a structure forming some of the first surface (210A), the second surface (210B), and the side (210C). According to one embodiment, the first surface (210A) may be formed by a front plate (202) (e.g., a glass plate or a polymer plate including various coating layers) in which at least a portion is substantially transparent. The second surface (210B) may be formed by a rear plate (211) that is substantially opaque. The rear plate (211) may be formed, for example, by coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials. The side (210C) may be formed by a side bezel structure (or "side member") (218) comprising metal and / or polymer, which is combined with the front plate (202) and the rear plate (211). In some embodiments, the rear plate (211) and the side bezel structure (218) may be formed integrally and may comprise the same material (e.g., a metallic material such as aluminum).

[0054] In the illustrated embodiment, the front plate (202) may include a first region (210D) that curves seamlessly from the first surface (210A) toward the rear plate at both ends of the long edge of the front plate.

In some embodiments, the front plate (202) or the rear plate (211) may include only one of the first region (210D) or the second region (210E). In some embodiments, the front plate (202) and the rear plate (211) may not include the first region and the second region, but may include only a flat plane positioned parallel to the second surface (210B). In the above embodiments, when viewed from the side of the electronic device, the side bezel structure (218) may have a first thickness (or width) on the side that does not include the first region (210D) or the second region (210E) as above, and may have a second thickness that is thinner than the first thickness on the side that includes the first region or the second region.

[0055] According to one embodiment, the electronic device (200) may include at least one of a display (201), an input device (203), an audio output device (207, 214), a sensor module (204, 219), a camera module (205, 212, 213), a key input device (217), an indicator (not shown), and a connector (208). In some embodiments, the electronic device (200) may omit at least one of the components (e.g., a key input device (217), or an indicator) or additionally include other components.

[0056] The display (201) may be exposed, for example, through a substantial portion of the front plate (202). In some embodiments, at least a portion of the display (201) may be exposed through the front plate (202) forming the first surface (210A) and the first area (210D) of the side (210C). The display (201) may be combined with or placed adjacent to a touch sensing circuit, a pressure sensor capable of measuring the intensity (pressure) of the touch, and / or a digitizer that detects a magnetic field-type stylus pen. In some embodiments, at least a portion of the sensor module (204, 219) and / or at least a portion of the key input device (217) may be placed in the first area (210D) and / or the second area (210E).

[0057] An input device (203) (e.g., an acoustic module, the input module (150) of FIG. 1) may include a microphone. In some embodiments, the input device (203) may include a plurality of microphones positioned to detect the direction of sound. According to one embodiment, the input device (203) may include an acoustic module for acquiring an external audio signal and an acoustic hole connected to the acoustic module and functioning as a path for the external audio signal. An acoustic output device (207, 214) may include speakers. The speakers may include an external speaker (207) and a receiver (214) for communication. In some embodiments, the microphone, speakers, and connector (208) are positioned in the space of the electronic device (200) and may be exposed to the external environment through at least one hole (e.g., an acoustic hole) formed in the housing (210). In some embodiments, the hole (e.g., an acoustic hole) formed in the housing (210) may be used for both the microphone and the speakers. In some embodiments, the acoustic output device (207, 214) may include a speaker (e.g., a piezo speaker) that is operated with a hole (e.g., an acoustic hole) formed in the housing (210) excluded. In some embodiments, the electronic device (200) may include a tray member disposed through at least a portion of the side bezel structure (218).

[0058] According to one embodiment, an input device (203) may include an acoustic hole corresponding to the path of an external audio signal and an acoustic module for acquiring the external audio signal. The electronic device (200) may acquire an audio signal transmitted from an external environment through the acoustic hole based on the acoustic module. For example, the acoustic hole may be implemented with various materials, shapes, and / or sizes, and as a result, the resonant frequencies may be implemented differently. If the electronic device (200) includes a plurality of input devices (203), the resonant frequencies of the acoustic holes corresponding to each of the plurality of input devices (203) may be determined differently. If the resonant frequency of the acoustic hole is not included in the range of the voice frequency band (e.g., a band of about 80 Hz to about 8 kHz), the quality (e.g., sound quality) of the voice signal transmitted through the acoustic hole may be improved. If the resonant frequency of the acoustic hole is determined to be outside the range of the voice frequency band, the distortion of the voice signal corresponding to the resonant frequency of the acoustic hole may be reduced.

[0059] According to one embodiment, the resonant frequency of the acoustic hole may be determined based on the size, length, and / or shape of the acoustic hole. For example, if at least one of the size, length, and / or shape of the acoustic hole is changed, the resonant frequency of the acoustic hole may also be changed. According to one embodiment, the electronic device (200) may change the size, length, and / or shape of the acoustic hole so that the resonant frequency of the acoustic hole falls outside the range of the voice frequency band (e.g., about 80 Hz to about 8 kHz band). The electronic device (200) may implement an internal space of a set size for the inner surface of the acoustic hole. The resonant frequency for the acoustic hole may be determined to be a value outside the range of the voice frequency band (e.g., about 80 Hz to about 8 kHz band) due to the internal space of the inner surface of the acoustic hole.

[0060] The sensor module (204, 219) can generate an electrical signal or data value corresponding to an internal operating state of the electronic device (200) or an external environmental state. The sensor module (204, 219) may include, for example, a first sensor module (204) (e.g., proximity sensor) and / or a second sensor module (not shown) (e.g., fingerprint sensor) disposed on a first surface (210A) of the housing (210), and / or a third sensor module (219) (e.g., HRM sensor) disposed on a second surface (210B) of the housing (210). The fingerprint sensor may be disposed on the first surface (210A) of the housing (210). The fingerprint sensor (e.g., ultrasonic or optical fingerprint sensor) may be disposed below the display (201) on the first surface (210A). The electronic device (200) may further include at least one of an unillustrated sensor module, for example, a gesture sensor, a gyroscope sensor, a barometric pressure sensor, a magnetic sensor, an accelerometer sensor, a grip sensor, a color sensor, an IR (infrared) sensor, a biosensor, a temperature sensor, a humidity sensor, or an illuminance sensor (204).

[0061] The camera modules (205, 212, 213) may include a first camera device (205) disposed on a first surface (210A) of the electronic device (200), a second camera device (212) disposed on a second surface (210B), and / or a flash (213). The camera modules (205, 212) may include one or more lenses, an image sensor, and / or an image signal processor. The flash (213) may include, for example, a light-emitting diode or a xenon lamp. In some embodiments, two or more lenses (wide-angle and telephoto lenses) and image sensors may be disposed on one surface of the electronic device (200).

[0062] A key input device (217) may be placed on the side (210C) of the housing (210). In one embodiment, the electronic device (200) may not include some or all of the aforementioned key input devices (217), and the key input device (217) that is not included may be implemented in other forms, such as soft keys, on the display (201). In one embodiment, the key input device (217) may be implemented using a pressure sensor included in the display (201).

[0063] An indicator may be placed, for example, on a first surface (210A) of a housing (210). The indicator may, for example, provide status information of an electronic device (200) in the form of light. In one embodiment, a light-emitting element may, for example, provide a light source that is coupled with the operation of a camera module (205). The indicator may include, for example, an LED, an IR LED, and a xenon lamp.

[0064] The connector hole (208) may include a first connector hole (208) capable of accommodating a connector (e.g., a USB connector or an IF module (interface connector port module)) for transmitting and receiving power and / or data with an external electronic device, and / or a second connector hole (or earphone jack) capable of accommodating a connector for transmitting and receiving audio signals with an external electronic device.

[0065] Some of the camera modules (205, 212), some of the sensor modules (204, 219), or indicators may be positioned to be exposed through the display (201). For example, the camera module (205), sensor module (204), or indicator may be positioned to come into contact with the external environment through an opening or a transparent area perforated to the front plate (202) of the display (201) within the internal space of the electronic device (200). In one embodiment, the area where the display (201) and the camera module (205) face each other may be formed as a transparent area having a certain transmittance as part of the area for displaying content. In one embodiment, the transparent area may be formed to have a transmittance in the range of about 5% to about 20%. This transparent area may include an area that overlaps with the effective area (e.g., field of view area) of the camera module (205) through which light passes to form an image and generate an image by being formed by an image sensor. For example, the transparent area of ​​the display (201) may include an area with a lower pixel density than the surrounding area. For example, the transparent area may replace the opening. For example, the camera module (205) may include an under-display camera (UDC). In one embodiment, some sensor modules (204) may be positioned to perform their functions without being visually exposed through the front plate (202) within the internal space of the electronic device. For example, in this case, the perforated opening may be unnecessary for the area of ​​the display (201) facing the sensor modules.

[0073] FIG. 4 is a cross-sectional view illustrating the shape of an acoustic hole connected to an acoustic module of an electronic device according to one embodiment of the present disclosure. FIG. 5 is a cross-sectional view illustrating an acoustic hole according to one embodiment of the present disclosure divided into a plurality of spaces.

[0074] FIGS. 4 and FIGS. 5 are cross-sectional views of an input device (e.g., input device (203) of FIG. 2a, acoustic module (410)) cut along the A-A' line of FIG. 2a.

[0075] FIGS. 4 and 5 are cross-sectional views of an acoustic module (410) and an acoustic hole (420) connected to the acoustic module (410). One end of the acoustic hole (420) may be at least partially exposed to the external environment, and the other end of the acoustic hole (420) may be electrically or operatively connected to the acoustic module (410). For example, the acoustic hole (420) may function as an audio transmission path through which an external audio signal is transmitted. For example, the audio signal may be transmitted to the acoustic module (410) while being at least partially reflected by the inner surface of the acoustic hole (420).

[0076] The electronic device (200) of FIGS. 4 and 5 may be at least partially similar to the electronic device (101) of FIG. 1 and / or the electronic device (200) of FIG. 2a, or may further include other embodiments of the electronic device (101). FIG. 4 is a drawing in which other components disposed adjacent to the acoustic module (410) and the acoustic hole (420) are shown together, and FIG. 5 is a drawing centered on the side member (401) (e.g., the side member (218) of FIG. 2a) and the bracket (402) (e.g., the extension member (2181) of FIG. 3) that implement the acoustic hole (420).

[0077] Referring to FIGS. 4 and 5, the electronic device (200) may include a structure in which a side member (401) (e.g., side member (218) in FIG. 2a) and a bracket (402) (e.g., extension member (2181) in FIG. 3) are at least partially joined by a connecting member (403). For example, the bracket (402) may be structurally joined to the side member (401) or formed integrally with the side member (401). The bracket (402) may also function as a support member that supports the display of the electronic device (200) (e.g., display (201) in FIG. 2a). The electronic device (200) may include a rear cover (404) (e.g., rear plate (211) in FIG. 2b) in a shape that encloses a part of the side member (401) and the bracket (402).

[0078] Referring to FIGS. 4 and 5, the bracket (402) may be at least partially coupled to the acoustic module (410) (e.g., the input device (203) of FIG. 2a). The side member (401) and the bracket (402) of the electronic device (200) may be designed to include an acoustic hole (420) connected to the acoustic module (410). For example, one end of the acoustic hole (420) may be positioned to be exposed to the external environment, and the other end of the acoustic hole (420) may be positioned to be connected to the acoustic module (410). The acoustic hole (420) may include a straight conduit and / or a curved conduit. In a situation where the electronic device (200) acquires an external audio signal, the external audio signal may be transmitted to the acoustic module (410) through the acoustic hole (420). For example, an external audio signal can be transmitted to the acoustic module (410) while being at least partially reflected on the inner surface of the acoustic hole (420). When viewed from the outside environment, the acoustic hole (420) may appear as an opening (e.g., hole, opening) corresponding to the first space (421).

[0079] Referring to FIGS. 4 and 5, the acoustic hall (420) may be divided into a first space (421), a second space (422), and / or a third space (423). For example, the first space (421), the second space (422), and / or the third space (423) may be implemented in the form of columns. The column form may include one of a cylinder with a circular base, a triangular prism with a triangular base, a square prism with a square base, and / or a polygonal prism with a polygonal base. For example, a first cylinder corresponding to the first space (421), a second cylinder corresponding to the second space (422), and / or a third cylinder corresponding to the third space (423) may be implemented. The first cylinder can be implemented with a base of the first diameter (501), the second cylinder can be implemented with a base of the second diameter (502), and the third cylinder can be implemented with a base of the third diameter (503). The first volume (e.g., first volume) corresponding to the first space (421) can be designed to be smaller than the second volume (e.g., second volume) corresponding to the second space (422). The second volume corresponding to the second space (422) can be designed to be relatively larger than the first volume corresponding to the first space (421) and the third volume corresponding to the third space (423). For example, the second diameter (502) of the second cylinder may be determined to be relatively larger than the first diameter (501) of the first cylinder and / or the third diameter (503) of the third cylinder. According to one embodiment, the acoustic hole (420) may be implemented as a straight path in the shape of a cylinder and may be implemented to include a second volume corresponding to the second space (422).

[0080] According to one embodiment, the first space (421), the second space (422), and / or the third space (423) are not limited to a specific type of column and can be implemented as columns of various shapes. For example, the first space (421), the second space (422), and / or the third space (423) can each be implemented to have various shapes based on components arranged around them.

[0081] According to one embodiment, the acoustic hole (420) may include a plurality of spaces (421, 422, 423) implemented in various shapes and sizes. The shape of the acoustic hole (420) is not limited to the shape shown in FIG. 4.

[0082] Referring to FIGS. 4 and 5, the side member (401) may be implemented in a form including a first space (421) and a second space (422) of the acoustic hole (420). The bracket (402) may be implemented in a form including a third space (423) of the acoustic hole (420).

[0083] According to one embodiment, the resonant frequency of the acoustic hole (420) may be determined based on the material, shape, and / or size of the acoustic hole (420). For example, if at least one of the material, shape, and / or size of the acoustic hole (420) is changed, the resonant frequency of the acoustic hole (420) may be changed. The electronic device (200) may change the shape and / or size of the acoustic hole (420) so that the acoustic hole (420) has a specific resonant frequency (e.g., a set resonant frequency). For example, the electronic device (200) may change the resonant frequency for the acoustic hole (420) by changing the shape of the side member (401) and the bracket (402).

[0084] According to one embodiment, a human voice signal may be formed based on a range of about 80 Hz to about 8 KHz (e.g., voice frequency band). According to one embodiment, the electronic device (200) may determine the shape and / or size of the acoustic hole (420) such that the resonant frequency of the acoustic hole (420) is outside the range of the voice frequency band (e.g., about 80 Hz to about 8 KHz band). Referring to FIG. 4, the acoustic hole (420) of the electronic device (200) may be modified in design to include an internal space (e.g., an internal space, a second space (422)) with respect to the inner surface. For example, the acoustic hole (420) may be implemented in the form of a hollow cylinder, such as a pipe or a tunnel. The acoustic hole (420) may function as a path for the audio signal to which an external audio signal is transmitted to the acoustic module (410). For example, if an internal space (e.g., an internal space, a second space (422), a space having a volume relatively larger than the first space (421)) is formed on the inner surface of the acoustic hole (420), the resonance frequency for the audio signal passing through the acoustic hole (420) may be increased.

[0085] According to one embodiment, the resonant frequency of the acoustic hole (420) can be determined based on the spatial volume (e.g., volume) of the acoustic hole (420). The resonant frequency of the acoustic hole (420) can be fixed at a specific frequency. For example, if the shape and size of the acoustic hole (420) are changed, the resonant frequency of the acoustic hole (420) can also be changed.

[0086] According to one embodiment, the electronic device (200) can determine a second volume corresponding to a second space (422) under conditions where the resonant frequency of the acoustic hole (420) is outside the range of the voice frequency band (e.g., about 80 Hz to about 8 kHz band). For example, if the second volume corresponding to the second space (422) increases, the resonant frequency of the acoustic hole (420) may also increase.

[0087] According to one embodiment, a second step corresponding to the inner surface of the second space (422) may be implemented relatively deeper than a first step corresponding to the inner surface of the first space (421). For example, the second step may be formed deeper than the first step by a set length (521), and the second step and the first step may be implemented in a stepped form. A second volume corresponding to the second space (422) may be implemented relatively larger than a first volume corresponding to the first space (421). For example, the first inner surface of the first space (421) (e.g., first step) and the second inner surface of the second space (422) (e.g., second step) may be implemented in a stepped form (e.g., stepped form). According to one embodiment, the first inner surface of the first space (421) and the second inner surface of the second space (422) are not limited to a stepped shape relative to each other.

[0088] According to one embodiment, the second space (422) may be implemented in a form that has a relatively larger volume than the first space (421). For example, the second space (422) may be implemented to have various shapes based on components arranged around it. For example, the first space (421) and the second space (422) may be implemented in various ways, as shown in FIGS. 7 to 12b.

[0089] According to one embodiment, at least one of the first space (421) and the second space (422) may be implemented in the form of a column (e.g., a prism with a polygonal cross-section and / or a cylinder with a circular cross-section). For example, at least one of the first space (421) and the second space (422) may be implemented in the form of various columns, such as a cylinder with a circular cross-section, a triangular prism with a triangular cross-section, and / or a square prism with a square cross-section.

[0090] FIG. 6 is a drawing illustrating the external shape of an acoustic hole when the internal structure of the acoustic hole is modified according to one embodiment of the present disclosure.

[0091] The electronic device (200) of FIG. 6 may be at least partially similar to the electronic device (101) of FIG. 1 and / or the electronic device (200) of FIG. 2a, or may further include other embodiments of the electronic device (101).

[0092] Referring to FIG. 6, a first acoustic hole (601) and a second acoustic hole (602) included in an electronic device (200) are illustrated. The first acoustic hole (601) and the second acoustic hole (602) can function as paths for an audio signal to which an external audio signal is transmitted to an acoustic module (e.g., the acoustic module (410) of FIG. 4).

[0093] For example, the first acoustic hole (601) may include a first cylinder (610) implemented with the same diameter. The first acoustic hole (601) may have a first resonant frequency value. For example, an audio signal transmitted through the first acoustic hole (601) may undergo a distortion phenomenon in which it is at least partially amplified based on the first resonant frequency value.

[0094] For example, the second acoustic hole (602) may include a second cylinder (620) in the form of a second-1 cylinder (621) implemented with a first diameter and a second-2 cylinder (622) implemented with a second diameter larger than the first diameter. The second cylinder (620) may be a cylinder in which the second-1 cylinder (621) and the second-2 cylinder (622) are at least partially combined. For example, the second-1 cylinder (621) may include a cylinder implemented based on a first cross-sectional area (631). The second-2 cylinder (622) may include a cylinder implemented based on a second cross-sectional area (632) set larger than the first cross-sectional area (631). According to one embodiment, the first diameter of the second-first cylinder (621) (e.g., the diameter of the first cross-sectional area (631)) may be the same as the diameter of the first cylinder (610) (e.g., the diameter of the base of the first cylinder (610). The internal space of the second acoustic hole (602) may be implemented to have a volume relatively larger than that of the first acoustic hole (601). For example, the volume of the second cylinder (620) may be relatively larger than the volume of the first cylinder (610). The second acoustic hole (602) may have a second resonant frequency value that is relatively larger than the first resonant frequency of the first acoustic hole (601). For example, an audio signal transmitted through the second acoustic hole (602) may undergo a distortion phenomenon in which it is at least partially amplified based on the second resonant frequency value.

[0095] For example, the first resonant frequency of the first acoustic hole (601) can be determined to be approximately 7.064 KHz, and the second resonant frequency of the second acoustic hole (602) can be determined to be approximately 8.094 KHz. As the volume of the second acoustic hole (602) increases compared to the volume of the first acoustic hole (601), the second resonant frequency can be determined to be relatively larger than the first resonant frequency. The opening of the second acoustic hole (602) exposed to the outside can be substantially the same as the opening of the first acoustic hole (601) exposed to the outside. Even if the first acoustic hole (601) is changed to the second acoustic hole (602), the electronic device (200) can maintain the same design in appearance. The second acoustic hole (602) may include a second-1 cylinder (621) of a first cross-sectional area (631) and a second-2 cylinder (622) of a second cross-sectional area (632). For example, the second cross-sectional area (632) may be set to be relatively larger than the first cross-sectional area (631).

[0096] According to one embodiment, in implementing acoustic holes (601, 602) in an electronic device (200), if the volume of the internal space of the acoustic holes (601, 602) increases, the resonance frequency value for the acoustic holes (601, 602) may increase. According to one embodiment, the electronic device (200) may change the design of the internal space (e.g., inner space, inner surface) of the acoustic holes so that the first acoustic hole (601) is changed to the second acoustic hole (602).

[0097] FIG. 7 is a drawing illustrating a first embodiment in which the shape and structure of an acoustic hole are modified according to an embodiment of the present disclosure. FIG. 8 is a drawing illustrating a second embodiment in which the shape and structure of an acoustic hole are modified according to an embodiment of the present disclosure. FIG. 9 is a drawing illustrating a third embodiment in which the shape and structure of an acoustic hole are modified according to an embodiment of the present disclosure. FIG. 10 is a drawing illustrating a fourth embodiment in which the shape and structure of an acoustic hole are modified according to an embodiment of the present disclosure. FIG. 11 is a drawing illustrating a fifth embodiment in which the shape and structure of an acoustic hole are modified according to an embodiment of the present disclosure.

[0098] FIGS. 7 through 11 illustrate various embodiments of an input device (e.g., the input device (203) of FIG. 2a, the acoustic module (410) of FIG. 4) cut along the A-A' line of FIG. 2a.

[0099] The electronic device (200) of FIGS. 7 to 11 may be at least partially similar to the electronic device (101) of FIG. 1 and / or the electronic device (200) of FIG. 2a, or may further include other embodiments of the electronic device (101).

[0100] FIGS. 7 through 11 illustrate various cross-sectional views of acoustic modules (710, 810, 910, 1010, 1110) and acoustic holes (720, 820, 920, 1020, 1120) (e.g., acoustic hole (420) of FIG. 4) connected to the acoustic modules (710, 810, 910, 1010, 1110). One end of the acoustic hole (720, 820, 920, 1020, 1120) may be at least partially exposed to the external environment, and the other end of the acoustic hole (720, 820, 920, 1020, 1120) may be electrically or operatively connected to the acoustic module (710, 810, 910, 1010, 1110). For example, the acoustic holes (720, 820, 920, 1020, 1120) can function as audio transmission paths through which external audio signals are transmitted. The acoustic holes (720, 820, 920, 1020, 1120) may include straight conduits and / or curved conduits. For example, the audio signal may be transmitted to the acoustic module (720, 820, 920, 1020, 1120) while being at least partially reflected by the inner surface of the acoustic holes (720, 820, 920, 1020, 1120).

[0101] The acoustic holes (720, 820, 920, 1020, 1120) of FIGS. 7 to 11 can be implemented in various forms based on the side member (401) (e.g., the side member (218) of FIG. 2a) and the bracket (402) (e.g., the extension member (2181) of FIG. 3) of the electronic device (200).

[0102] Referring to FIG. 7, the first acoustic hole (720) may be divided into a first-1 space (721), a first-2 space (722), and / or a first-3 space (723). For example, the first-1 space (721), the first-2 space (722), and / or the first-3 space (723) may be implemented in the form of columns. For example, the first-1 space (721), the first-2 space (722), and / or the first-3 space (723) may be implemented in the form of cylinders if the base is circular, and in the form of prisms corresponding to the polygon if the base is polygonal. If the base is triangular, each space may be implemented in the form of a triangular prism, and if the base is square, each space may be implemented in the form of a square prism. For example, the first acoustic hole (720) may include a first-1 cylinder corresponding to the first-1 space (721), a first-2 cylinder (e.g., an oblique cylinder) corresponding to the first-2 space (722), and / or a first-3 cylinder corresponding to the first-3 space (723). The first-2 volume corresponding to the first-2 space (722) may be designed to be relatively larger than the first-1 volume corresponding to the first-1 space (721). For example, one end of the first-second space (722) may be connected to the first-first space (721) and may be determined to a first diameter according to the first-first space (721), and the other end of the first-second space (722) may be connected to the first-third space (723) and may be determined to a second diameter that is relatively larger than the first diameter. The first-second cylinder corresponding to the first-second space (722) may be a cylinder whose diameter gradually increases in the direction from one end to the other end. The first acoustic hole (720) of FIG. 7 may be designed to include a first-second space (722) having a volume relatively larger than that of the first-first space (721).
