Description
Technical Field
[0001] Various embodiments of the present disclosure relate to an electronic device including a microphone module. Background Art
[0002] The microphone module included in the electronic device is a device that can receive external sound and convert it into an electrical signal. The microphone module can be used to perform various functions of the electronic device, such as a call function or an external sound recording function.
[0003] The microphone module is provided in the electronic device, and thus, a case constituting the appearance of the electronic device may have a portion in which a hole connected to the microphone module is formed in order to guide external sound to the microphone module provided in the electronic device. Summary of the invention
[0004] Technical issues
[0005] An external hole for receiving external sound may be formed in the appearance of the electronic device. The external hole and the microphone hole of the microphone module provided in the electronic device may be connected to each other through a channel formed in the electronic device. In an embodiment, the channel may be formed in a mechanism provided in the electronic device.
[0006] Meanwhile, considering the layout of components in the electronic device, the channel may be set to be curved in some parts. In this case, the sound introduced into the electronic device through the external hole may be refracted or reflected in the channel formed in the mechanism. Therefore, due to the refraction and reflection of the original sound generated from the outside, not all components can be smoothly introduced into the microphone module, so during voice recording or call, the internal processing of the electronic device uses only some components of the original sound, so that the acoustic performance of the microphone experienced by the user may be reduced.
[0007] According to the embodiments of the present disclosure, the path for sound to be transmitted to the microphone module is simplified, thereby improving the acoustic performance of the microphone module.

In addition, the electronic device may include a printed circuit board and a slit, the printed circuit board including a second acoustic hole, the microphone hole being disposed in the second acoustic hole, the slit being used to connect the first acoustic hole and the second acoustic hole, and when the first acoustic hole is observed from one side surface of the housing, the slit at least partially overlaps with the first acoustic hole.
[0012] Advantageous Effects of the Invention
[0013] According to the embodiment of the present disclosure, the channel for connecting the microphone hole of the microphone module and the external hole formed in the appearance of the electronic device can be linearized to reduce the refraction of sound. Therefore, the path for sound propagation to the microphone module can be simplified, thereby improving the acoustic performance of the microphone module. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 4b is along Figure 2a The cross-sectional view is taken along the line AA shown in FIG. 1 and shows the first acoustic hole and the Figure 4a A channel structure for connecting a microphone module arranged on a printed circuit board.
[0074] In the following, the same Figure 1 , Figure 2a , Figure 2b and Figure 3 The same or similar reference numerals as the elements described in the drawings are used to represent the same or similar elements. In addition, the description of the elements that are the same or similar to the above-mentioned elements is omitted.
[0075] According to an embodiment, the printed circuit board 440 (eg, Figure 3 The substrate 340 of the embodiment may include various connection holes 208 and gaps 441. The connection holes 208 may be formed by forming a gap in the housing 410 (e.g., Figure 2aAt least one hole formed in the housing 210 is exposed to the external environment. Figure 4a and Figure 5a , the connection hole 208 may be connected to an ear jack 471 connected to an earphone jack and a charging connector 472 connected to a power supply device. The ear jack 471 and the charging connector 472 may be exposed to the external environment through at least one hole (e.g., the connection hole 208) formed in the housing 410. In addition, various connection holes 208 may be provided on the printed circuit board 440.
[0076] According to the embodiment, referring to Figure 4a Although not shown, the microphone module 450 may be positioned between the ear jack 471 and the charging connector 472. In this case, the slit 441 may be positioned between the ear jack 471 and the charging connector 472 so as to be connected to the microphone hole 451 of the microphone module 450. The positions of the microphone module 450 and the slit 441 are merely exemplary, and the microphone module and the slit may be arranged and formed in various positions on the printed circuit board 440.
[0077] According to an embodiment, various mechanisms may be provided inside the housing 410. Here, the mechanism may be used to collectively refer to the electronic device 300 (eg, Figure 1 The electronic device 101 and Figure 2a The mechanism may include a first support member 421 (eg, a first support member 422 for supporting a printed circuit board 440) and a second support member 423 for supporting a printed circuit board 440. Figure 3 The first support member 311 and Figure 4b and Figure 5b The first support member 421 in the printed circuit board 440 and the second support member 422 (eg, Figure 3 The second support member 360 and Figure 4b and Figure 6 b). In addition, elements such as the microphone module 450 and the display 201 may be fixed or supported by the first supporting member 421 and the second supporting member 422 disposed inside the housing 410.
[0078] According to an embodiment, the housing 410 may be formed of various materials. For example, the housing 410 may be formed of a metal material or a synthetic resin material, or may be formed of a composite material. The housing 410 may have several segmented parts, which are connected to each other in various ways (e.g., by adhesive bonding, by welding bonding, or by bolting). The shape, material, and forming method of the above-mentioned housing 410 are merely illustrative, and the housing 410 may be changed in various ways within the scope that can be understood by those skilled in the art. Figure 4a and Figure 4b The shape of the housing 410 shown in FIG. 4 is provided only as an example and is not limited to the shape of the housing 410 described in the present disclosure.
[0079] According to an embodiment, the microphone module 450 may be provided inside the housing 410. The microphone module 450 is a device that converts sound into an electrical signal. For example, when the sound transmitted to the microphone module 450 causes a vibration plate (not shown) included in the microphone module 450 to vibrate, an element (e.g., a coil (not shown)) that generates an electrical signal in association with the vibration of the vibration plate may generate an electrical signal.
[0080] In an embodiment, the microphone module 450 may be disposed on the printed circuit board 440 and disposed at a position adjacent to the first acoustic hole 412 formed in the housing 410. External sound may be transmitted to the microphone module 450 through the first acoustic hole 412. The microphone module 450 may be disposed at a position adjacent to the first acoustic hole 412, so that a phenomenon in which the external sound is lost or the sound waveform is changed in the process of transmitting the external sound to the microphone module 450 may be minimized.
[0081] According to an embodiment, the first acoustic hole 412 may be formed in the housing 410. Figure 2a , Figure 2b , Figure 4b and Figure 5b , the first acoustic hole 412 may be formed in the housing 410 (eg, Figure 2a The side surface of the housing 210) (for example, referring to Figure 2a , on the surface facing the Y direction). In an embodiment, the first acoustic hole 412 may be formed in a frame 411 constituting the appearance of the housing 410 (eg, Figure 2a The side surface frame structure 218 and Figure 3 In an embodiment, the frame 411 may be formed separately from the body of the housing 410 and may be coupled to the side surface of the housing 410. In an embodiment, the frame 411 may be formed integrally with the housing 410 and may refer to a portion of the side surface of the housing 410.
[0082] The following describes a channel. A channel (e.g., Figures 4a to 5b The gap 411 in the passage may refer to a passage that guides the propagation of sound (waveform). For example, a channel may refer to a physical space. A channel may include a space filled with a medium (e.g., air) that can transmit a waveform. Hereinafter, when sound propagates through the channel, it may refer to that the sound propagates through a specific space. In addition, when elements are connected through the channel, it may refer to that the space indicated by the element and the specific space are connected to each other.
[0083] According to an embodiment, a passage for connecting the first acoustic hole 412 of the microphone module 450 and the microphone hole 451 may be positioned in the housing 410. In an embodiment, referring to Figure 4a , Figure 4b , Figure 5a and Figure 5b , the printed circuit board 440 may include a plurality of Figure 4b In an embodiment, the slit 441 may extend from an end of the printed circuit board 440 facing the first acoustic hole 412 toward the microphone hole 451. In an embodiment, as shown in FIG. Figure 4b As shown, the microphone module 450 may be disposed on the printed circuit board 440 so that the microphone hole 451 is positioned in the slit 441 of the printed circuit board 440. Therefore, external sound may be transmitted to the microphone hole 451 of the microphone module 450 by sequentially passing through the slit 441 of the printed circuit board 440 and the first acoustic hole 412 formed in the frame 411.
[0084] In the embodiments, reference Figure 4b , the gap 441 may at least partially overlap with the first acoustic hole 412. For example, when observing a surface of the housing 410 having the first acoustic hole 412 therethrough (eg, reference Figure 4bWhen the slit 441 is at least partially overlapped with the first acoustic hole 412, the slit 441 may at least partially overlap with the first acoustic hole 412. According to an embodiment of the present disclosure, the microphone hole 451 of the microphone module 450 may be connected to the first acoustic hole 412 through the slit 441. The slit 441 may extend from one end of the printed circuit board 440 facing the first acoustic hole 412 to the microphone hole 451. In addition, when observing a surface of the housing 410 having the first acoustic hole 412 running through it, the slit 441 may partially overlap with the first acoustic hole 412. In this case, the acoustic path from the first acoustic hole 412 through the slit 441 to the microphone hole 451 may be at least partially straightened. At the same time, when the external sound is refracted or bent, the degree of sound transmitted to the microphone module 450 may be reduced or distorted. According to an embodiment of the present disclosure, compared with the case where the first acoustic hole 412 and the slit 441 do not overlap each other, in the case where the external sound passes through the first acoustic hole 412, the phenomenon that the sound path in the housing 410 is refracted or bent can be improved. In this case, a path for the external sound to be transmitted to the microphone module 450 is simplified, so that the degree of sound recognition by the microphone module 450 can be improved.
[0085] According to an embodiment, the slit 441 may form a channel structure for connecting the first acoustic hole 412 and the microphone hole 451 through the soundproof members 511 and 512. Figure 4b The soundproofing members 511 and 512 may include a first surface (eg, reference Figure 4b , the surface facing the +Z direction) to cover the first soundproof member 511 of the gap 441. In addition, the soundproof members 511 and 512 may include a first soundproof member 511 disposed on the second surface of the printed circuit board 440 (eg, reference Figure 4b , a surface facing the −Z direction) to cover the second soundproof member 512 of the slit 441. The slit 441 may have a surface open toward the first surface of the printed circuit board 440 and covered by the first soundproof member 511, and may have a surface open toward the second surface of the printed circuit board 440 and covered by the second soundproof member 512. Therefore, the external sound transmitted to the slit 441 may not escape around the first soundproof member 511 and the second soundproof member 512.
[0086] In an embodiment, the sound insulation members 511 and 512 may be formed of various materials. For example, the sound insulation members 511 and 512 may be formed of materials such as rubber, polyurethane, or silicone. The sound insulation members 511 and 512 may shield the gap 441 to prevent the sound introduced into the gap 441 from the first acoustic hole 412 from escaping to the surroundings. Therefore, the sound introduced through the first acoustic hole 412 may be transmitted to the microphone hole 451 through the gap 441.
[0087] According to an embodiment, Figure 4b As shown, a first support member 421 for supporting a first surface of a printed circuit board 440 and a second support member 422 for supporting a second surface of the printed circuit board 440 may be arranged in the housing 410. The first support member 421 may support the printed circuit board 440 and / or electronic components disposed in the housing 410. The second support member 422 may be disposed to face the first support member 421 to support the electronic components and / or the printed circuit board 440 disposed on the first support member 421. In an embodiment, referring to Figure 4b , the second support member 422 may include a groove 423 for receiving the microphone module 450 disposed on the printed circuit board 440. The microphone module 450 may be positioned in the groove 423 of the second support member 422.
[0088] In an embodiment, the first soundproofing member 511 may be positioned between the first support member 421 and the first surface of the printed circuit board 440 (eg, see Figure 4b , facing the +Z direction). The second soundproofing member 512 may be positioned between the second supporting member 422 and the second surface of the printed circuit board 440 (eg, referring to Figure 4b , the surface facing the -Z direction). The first soundproof member 511 can reduce the impact transmitted to the printed circuit board 440 through the first supporting member 421. Similarly, the second soundproof member 512 can reduce the impact transmitted to the printed circuit board 440 through the second supporting member 422. Therefore, the printed circuit board 440 can be protected from external impact by the first soundproof member 511 and the second soundproof member 512.
[0089] According to an embodiment, Figure 4b As shown, an acoustic space 431 may be formed between the first supporting member 421 and the second supporting member 422. The acoustic space 431 may be a space for connecting the first acoustic hole 412 and the gap 441. In an embodiment, external sound may be transmitted to the microphone hole 451 through the first acoustic hole 412, the acoustic space 431, and the gap 441.
[0090] In the embodiments, reference Figure 4b , the acoustic space 431 may have a direction from the slit 441 toward the first acoustic hole 412 (eg, referring to Figure 4b Here, the area can refer to the area of Figure 4b In other words, the acoustic space 431 may have an area in the direction from the first acoustic hole 412 toward the slit 441 (for example, referring to Figure 4b Therefore, the sound introduced through the first acoustic hole 412 can be transmitted to the microphone hole 451 through the gap 441 without being scattered.
[0091] In the embodiments, reference Figure 4b At least one sealing member 520 may be provided in the acoustic space 431. The sealing member 520 may include a waterproof portion and a mesh structure for blocking foreign matter. Therefore, the sealing member 520 may block external foreign matter and / or solution introduced through the first acoustic hole 412.
[0092] The above Figure 4a and Figure 4b The channel structure of the electronic device 300 described is provided only as an example, and besides this, the microphone channel structure may be changed in various ways.
[0093] Figure 5a Shows different from Figure 4a An embodiment of a printed circuit board is a printed circuit board. Figure 5b is along Figure 2a A cross-sectional view taken along the line AA shown in FIG. 1 and showing a first acoustic hole for connecting the housing and a first acoustic hole for connecting the housing and a first acoustic hole for connecting the housing. Figure 5a Channel structure of microphone module on printed circuit board.
[0094] The channel structure described below can be Figure 4a and Figure 4b The channel structure of the embodiment different from the channel structure described in the above Figure 4a and Figure 4b Unless otherwise specified, the same reference numerals are used for the elements that are the same or similar to the elements described in the above description. In addition, the description of the elements that are the same or similar to the above elements is omitted.
[0095] According to the embodiment, Figure 5a As shown, a printed circuit board 440 (eg, Figure 3 The substrate 340 in the printed circuit board 440 may include a slit 441, a second acoustic hole 442, and a connector (e.g., an ear jack 471 and / or a charging connector 472). In an embodiment, the microphone module 450 may be disposed on the printed circuit board 440 so that the microphone hole 451 is located in the second acoustic hole 442. The slit 441 may be a portion of the housing 410 (e.g., Figure 2a The microphone module 450 is provided to provide a path for transmitting external sound introduced from the first acoustic hole 412 of the housing 210 in the case 210 to the microphone hole 451. In an embodiment, the microphone module 450 may be located between the ear jack 471 and the charging connector 472. In this case, the slit 441 and the second acoustic hole 442 may be located between the ear jack 471 and the charging connector 472 to transmit the external sound introduced from the first acoustic hole 412 to the microphone hole 451. The positions of the microphone module 450 and the slit 441 are merely exemplary, and the microphone module and the slit may be arranged and formed in various positions on the printed circuit board 440.
[0096] According to the embodiment, Figure 5a and Figure 5b As shown, the slit 441 may extend from one end of the printed circuit board 440 facing the first acoustic hole 412 toward the second acoustic hole 440. The housing 410 may include an acoustic passage 432 for guiding the external sound introduced into the slit 441 through the first acoustic hole 412 to the second acoustic hole 442. In an embodiment, the acoustic passage 432 may be formed in the housing 410. For example, referring to Figure 5b , the acoustic channel 432 may be formed in the first support member 421 (eg, Figure 3 The external sound may be introduced into the microphone hole 451 through the first acoustic hole 412, the acoustic space 431, the gap 441, the acoustic channel 432, and the second acoustic hole 442 formed at the side surface of the housing 410. The microphone module 450 may recognize the external sound propagated from the first acoustic hole 412.
[0097] In the embodiments, reference Figure 5b , the gap 441 may at least partially overlap with the first acoustic hole 412. For example, when observing a surface of the housing 410 having the first acoustic hole 412 formed therethrough (eg, referring to Figure 4b In the +Y direction of the housing 410, the slit 441 may at least partially overlap with the first acoustic hole 412. In this case, the acoustic path from the first acoustic hole 412 to the slit 441 may be at least partially linearized. In addition, when observing a surface of the housing 410 having the first acoustic hole 412 formed therethrough (for example, referring to Figure 4b When the first acoustic hole 412 is refracted or bent, the acoustic path 432 may be at least partially overlapped with the first acoustic hole 412 (in the +Y direction). In this case, the acoustic path from the first acoustic hole 412 to the acoustic path 432 through the slit 441 may be at least partially linearized. At the same time, when the external sound is refracted or bent, the degree of sound transmitted to the microphone module 450 may be reduced or distorted. According to an embodiment of the present disclosure, in the case where the external sound passes through the first acoustic hole 412, the phenomenon that the acoustic path in the housing 410 is refracted or bent can be enhanced, compared to the case where the first acoustic hole 412 and the slit 441 do not overlap with each other and / or the first acoustic hole 412 and the acoustic path 432 do not overlap with each other. The path for the external sound to be transmitted to the microphone module 450 is simplified, and thus the degree of sound recognition performed by the microphone module 450 can be improved.
[0098] According to an embodiment, the slit 441 may form a channel structure for transferring external sound introduced through the first acoustic hole 412 to the acoustic channel 432 through the soundproof members 511 and 512. Figure 5bThe soundproofing members 511 and 512 may include a first soundproofing member 511 disposed on a first surface of the printed circuit board 440 (eg, referring to Figure 5b , the surface facing the +Z direction) to cover the gap 441. The first soundproof member 511 may cover a portion of the gap 441 on the first surface of the printed circuit board 440 so that the gap 441 and the acoustic channel 432 can be connected to each other. In addition, the soundproof members 511 and 512 may include a second soundproof member 512, which is disposed on the second surface of the printed circuit board 440 (for example, referring to Figure 5b , the surface facing the -Z direction) to cover the slit 441. The slit 441 may have a surface open toward the first surface of the printed circuit board 440 at least partially covered by the first soundproof member 511, and may have a surface open toward the second surface of the printed circuit board 440 covered by the second soundproof member 512. Therefore, the external sound transmitted to the slit 441 may not escape around the first soundproof member 511 and the second soundproof member 512.
[0099] In an embodiment, the first soundproof member 511 can reduce the impact transmitted to the printed circuit board 440 through the first supporting member 421. Likewise, the second soundproof member 512 can reduce the impact transmitted to the printed circuit board 440 through the second supporting member 422. Therefore, the printed circuit board 440 can be protected from external impact by the first soundproof member 511 and the second soundproof member 512.
[0100] Through the above Figure 5a and Figure 5b The electronic device 300 (eg, Figure 1 The electronic device 101 and / or Figure 2a The channel structure of the electronic device 200) is provided only as an example, and other than that, the microphone channel structure may be changed in various ways.
[0101] Figure 6 A microphone module according to an embodiment of the present disclosure is shown.
[0102] According to the embodiment, Figure 6 As shown, the microphone module 450 may be connected to the printed circuit board 440 (eg, Figure 3 The solder ring 460 may be positioned between the microphone module 450 and the printed circuit board 440 to surround the microphone hole 451 of the microphone module 450. In an embodiment, Figure 6 Parts (a) and (b) show that the microphone hole 451 of the microphone module 450 is positioned as shown in FIG. Figure 4a and 4bThe structure of the solder ring 460 in the case of the gap 441 is described. In this case, the solder ring 460 can surround the gap 441 of the printed circuit board 440 and the microphone hole 451 of the microphone module 450. Therefore, the external sound that has passed through the first acoustic hole 412, the acoustic space 431 and the gap 441 can be transmitted to the microphone hole 451 without escaping between the printed circuit board 440 and the microphone module 450. In an embodiment, Figure 6 Part (c) shows that the microphone hole 451 of the microphone module 450 is formed in Figure 5a and 5b The structure of the solder ring 460 in the case of the second acoustic hole 442 formed on the printed circuit board 440. In this case, the solder ring 460 can be positioned between the microphone module 450 and the printed circuit board 440 to surround the second acoustic hole 442 and the microphone hole 451 of the microphone module 450. Therefore, the external sound passing through the first acoustic hole 412, the acoustic space 431, the gap 441 and the acoustic channel 432 can be transmitted to the microphone hole 451 without escaping between the printed circuit board 440 and the microphone module 450.
[0103] Figure 7a shows the acoustic performance of the microphone according to the embodiment of the present disclosure, Figure 7b The acoustic performance of a microphone according to an embodiment of the present disclosure is shown.
[0104] In an embodiment, Figure 7a 4 shows the microphone performance of the microphone module 450 disposed on the printed circuit board 440 on which the slit 441 is not formed. Figure 7a The acoustic path shown in the figure may include a first acoustic hole 412, an acoustic space 431, an acoustic channel 432, and a second acoustic hole 442. For example, external sound may be transmitted to the microphone hole 451 through the first acoustic hole 412, the acoustic space 431, the acoustic channel 432, and the second acoustic hole 442. At the same time, when a gap 441 that at least partially overlaps with the first acoustic hole 412 is not formed on the printed circuit board 440, the acoustic path may be relatively curved compared to a case where the gap 441 is formed on the printed circuit board 440. For example, the acoustic path from the first acoustic hole 412 to the acoustic channel 432 may have a relatively curved structure. In this case, the original sound generated from the outside (for example, the sound in the high frequency band, which is relatively weak to refraction) is repeatedly refracted and reflected, so not all components of the external sound can be smoothly introduced into the microphone module 450. Therefore, during voice recording or a call, the electronic device 300 (for example, Figure 1 The electronic device 101 and Figure 2a In the electronic device 200 , internal processing is performed by using only some components of the original sound, so the microphone acoustic performance experienced by the user may be deteriorated.
[0105] In an embodiment, Figure 7b As shown in Figure 4b The performance of the microphone module 450 is shown when the acoustic path from the first acoustic hole 412 to the microphone hole 451 through the gap 441 is at least partially linearized. Figure 2a When the first acoustic hole 412 is formed on a surface of the housing 210 in the housing 210, the slit 441 may at least partially overlap the first acoustic hole 412. In this case, the acoustic path from the first acoustic hole 412 to the microphone hole 451 through the slit 441 may be at least partially linearized. At the same time, as described above, when the sound in the high frequency band is refracted or bent, it may be difficult to introduce the sound into the microphone module 450. For example, Figure 7a As shown, the acoustic path from the first acoustic hole 412 to the second acoustic hole 442 through the acoustic space 431 and the acoustic channel 432 is curved, so the sound in the high frequency band may be refracted or bent in the acoustic path. In this case, not all components of the external sound can be smoothly introduced into the microphone module 450. According to an embodiment of the present disclosure, when the slit 441 is formed on the printed circuit board 440, the acoustic path from the first acoustic hole 412 to the microphone hole 451 can be simplified, compared to the case where the slit 441 is not formed on the printed circuit board 440. For example, the acoustic path from the first acoustic hole 412 to the microphone hole 451 through the slit 441 can be at least partially linearized, thereby alleviating the phenomenon that the external sound is reflected and / or refracted in the acoustic path. In this case, the degree to which the sound in the high frequency band is introduced into the microphone module 450 can be enhanced. For example, referring to Figure 7b It can be recognized that when the external sound moves from the first acoustic hole 412 to the microphone hole 451 through the gap 441, Figure 7a In comparison, the sound pressure at the peak frequency of the microphone enhanced in the corresponding structure is enhanced. Figure 7b The peak frequency of the microphone in is 8.62KHz, which is Figure 7a This frequency is enhanced compared to the microphone peak frequency of 7.22KHz in the Figure 7a Compared with the acoustic path, Figure 7b The acoustic path may allow high-frequency sounds to be more smoothly transmitted to the microphone module 450. Therefore, the performance of the microphone module 450 in acquiring sounds having high-frequency components may be improved.
