Description
Technical Field
[0001] This utility model relates to the field of electronic equipment technology, and in particular to a sound pickup component and an electronic device. Background Technology
[0002] With the expansion of the functions and playability of various electronic devices, in some scenarios, these devices need to pick up sound from a target direction while suppressing sound from directions other than the target sound source to improve the clarity of the target sound source and thus achieve high-quality sound pickup. Related technologies employ omnidirectional microphone arrays, relying on beamforming technology to identify sound only from specific angles and suppress sound from other angles to achieve noise reduction. However, to achieve directional functionality, multiple omnidirectional microphones need to work together, thus requiring a significant amount of space and greatly increasing the difficulty of industrial design and stacking of electronic devices. Utility Model Content
[0003] Therefore, this utility model provides a sound pickup component and an electronic device that can achieve both unidirectional and bidirectional sound pickup functions while occupying a small space. The technical solution is as follows:
[0004] In a first aspect, a sound pickup assembly is provided, the sound pickup assembly including a directional microphone, an omnidirectional microphone and a mixing module;
[0005] The directional microphone includes a first pickup port and a second pickup port, which are used to pick up sounds from different directions, respectively.
[0006] The omnidirectional microphone includes a third pickup port;
[0007] The mixing module is connected to the directional microphone and the omnidirectional microphone respectively, and the mixing module is used to mix the sound signals from the directional microphone and the omnidirectional microphone and then output them.
[0008] The pickup component in this embodiment can mix the first audio signal received by the directional microphone and the second audio signal received by the omnidirectional microphone using a mixing module before outputting the signal. Therefore, unidirectional sound transmission can be achieved when both the directional and omnidirectional microphones are on; and bidirectional sound transmission can be achieved when the omnidirectional microphone is off and the directional microphone is on.
[0009] In some possible implementations, the pickup assembly further includes a housing, the outer surface of which includes a first sound guide groove and a second sound guide groove, wherein the opening orientation of the first sound guide groove is different from the opening orientation of the second sound guide groove;

[0012] The third pickup port is connected to either the second sound guide slot or the first sound guide slot.
[0013] The third pickup port of the omnidirectional microphone of the pickup assembly can simultaneously pick up sound through the second sound guide groove along with the second pickup port of the directional microphone. This reduces the number of ID holes on the surface of the housing, which helps to improve the aesthetics of the appearance and also reduces the difficulty of waterproofing.

[0027] The second sound guide groove is formed on the first half-shell, or on the second half-shell, or between the first half-shell and the second half-shell.
[0028] The first and second half-shells of the electronic device can clamp and fix the printed circuit board, thereby protecting and shielding the directional microphone, omnidirectional microphone and printed circuit board, while facilitating the installation of the microphone on the printed circuit board.
[0029] In some possible implementations, the printed circuit board includes a first through-hole and a second through-hole;
[0030] The second half-shell includes a first communicating groove and a second communicating groove;
[0031] Both the first connecting slot and the second connecting slot are covered on the second side of the printed circuit board;
[0032] One of the first pickup port and the second pickup port is sequentially connected to the first through hole and the first connecting groove, and the third pickup port is sequentially connected to the second through hole and the second connecting groove;

[0034] The volume of the sound guide channel between the first sound guide groove and the first sound guide port of the pickup assembly is roughly the same as that between the second sound guide port and the second sound guide port, which helps to improve the sound pickup effect of the directional microphone.
[0035] In some possible implementations, the housing further includes a first seal and a second seal;

[0049] The first and second sound guide slots of the electronic device are strip-shaped, which allows for a greater distance between the speaker's sound-emitting part and the microphone's pickup port, thus avoiding interference between the sound emitted by the speaker and the sound received by the pickup port. At the same time, it also provides good concealment while ensuring sufficient sound guide space, contributing to the aesthetics of the device's design.

Detailed Implementation
[0075] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0076] Firstly, this embodiment relates to a sound pickup structure for an electronic device. The electronic device can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or smartphone. Examples include iPhone™-based phones, Android™-based phones, portable gaming devices such as Nintendo DS™, PlayStation Portable™, Gameboy Advance™, iPhone™, laptops, PDAs, portable internet devices, music players, and data storage devices, other handheld devices, and devices such as headphones. The electronic device can also be other wearable devices that require charging, such as head-mounted devices (HMDs) like electronic bracelets, electronic necklaces, electronic devices, or smartwatches.
[0077] Electronic devices can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smartphones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transport instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbooks, personal digital assistants (PDAs), portable multimedia players (PMPs), MPEG-1 or MPEG-G-2 audio layer 3MP3 players from the Moving Image Experts Group, portable medical devices, and digital cameras and combinations thereof.
[0078] In some cases, electronic devices can perform multiple functions (e.g., playing music, displaying video, storing pictures, and receiving and sending telephone calls). If desired, electronic devices can be such as cellular phones, media players, other handheld devices, wristwatches, pendant devices, handset devices, or other compact portable devices.
[0079] refer to Figure 1 As shown, the sound pickup structure in this embodiment includes a directional microphone 200, an omnidirectional microphone 400, and a mixing module 500.
[0080] The directional microphone 200 includes a first pickup port 201 and a second pickup port 202, which are used to pick up sound from different directions. For example, the first pickup port 201 can be used to pick up sound from the front of the electronic device, and the second pickup port 202 can be used to pick up sound from the rear of the electronic device. Alternatively, the first pickup port 201 can pick up sound from the rear of the electronic device, and the second pickup port 202 can pick up sound from the front of the electronic device. The directional microphone 200 can convert the picked-up sound into a first sound signal.
[0081] The omnidirectional microphone 400 includes a third pickup port 401, which can generally pick up sound from all directions. The omnidirectional microphone 400 can convert the picked-up sound into a second audio signal.
[0082] The mixing module 500 is connected to the directional microphone 200 and the omnidirectional microphone 400 respectively. The mixing module 500 is used to mix the audio signals from the directional microphone 200 and the omnidirectional microphone 400 and then output them to the outside.
[0083] The mixing module 500 can be hardware such as a mixer or DSP, or analog software such as Ableton Live or Pro Tools. Accordingly, the mixing module 500 can include two input ports, one for receiving a first audio signal and the other for receiving a second audio signal. The mixing module 500 can output a third audio signal obtained by mixing the first and second audio signals from the output port.
[0084] For example, the mixing module 500 can amplify the first sound signal obtained by processing the sound picked up by the first pickup port 201 with the directional microphone 200 and the second sound signal obtained by processing the sound picked up by the third pickup port 201 with the omnidirectional microphone 400, and reduce the first sound signal obtained by processing the sound picked up by the second pickup port 202 with the directional microphone 200 and the second sound signal obtained by processing the sound picked up by the third pickup port 201 with the omnidirectional microphone 400.
[0085] In this way, when sound comes from the front, both the first and third microphone ports 201 can pick up the sound, allowing the mixing module 500 to amplify the first and second sound signals by superimposing them, thus ensuring that the sound from the front is clearly output. Conversely, when sound comes from the rear, both the second and third microphone ports 202 and 201 can pick up the sound, allowing the mixing module 500 to reduce the sound by canceling out the first and second sound signals, thus reducing or even eliminating the sound from the rear. Therefore, with both the directional microphone 200 and the omnidirectional microphone 400 activated, forward unidirectional directionality of the microphone assembly can be achieved.
[0086] For example, when both the directional microphone 200 and the omnidirectional microphone 400 are turned on, the mixing module 500 can cancel out and reduce the first sound signal obtained by processing the sound picked up by the first pickup port 201 with the directional microphone 200, and increase the sound signal obtained by processing the sound picked up by the third pickup port 201 with the omnidirectional microphone 400, and add together the first sound signal obtained by processing the sound picked up by the second pickup port 202 with the directional microphone 200, and increase the sound signal obtained by processing the sound picked up by the third pickup port 201 with the omnidirectional microphone 400.
[0087] Thus, when sound comes from the front, both the first and third microphone ports 201 can pick up the sound, allowing the mixing module 500 to cancel out the first and second sound signals, thereby reducing or even eliminating the sound from the front. Conversely, when sound comes from the rear, both the second and third microphone ports 202 and 201 can pick up the sound, allowing the mixing module 500 to superimpose the first and second sound signals, thus amplifying the sound and ensuring that the sound from the rear is clearly output. Therefore, with both the directional microphone 200 and the omnidirectional microphone 400 activated, unidirectional rear-facing sound pickup can be achieved.
[0088] For example, the omnidirectional microphone 400 can be turned off and the directional microphone 200 can be turned on, so that the first sound signal can be received while the mixing module 500 cannot receive the second sound signal. Therefore, the sound signal output by the output port of the mixing module 500 can be the same as the first sound signal, thereby achieving bidirectional directionality.
[0089] As described above, the sound pickup component can use the mixing module 500 to mix the first sound signal received by the directional microphone 200 and the second sound signal received by the omnidirectional microphone 400 before outputting the signal. Therefore, unidirectional sound can be achieved when both the directional microphone 200 and the omnidirectional microphone 400 are on; and bidirectional sound can be achieved when the omnidirectional microphone 400 is off and the directional microphone 200 is on.
[0090] In some possible implementations, refer to Figure 2 As shown, the sound pickup assembly also includes a housing 100, the outer surface of which includes a first sound guide groove 1 and a second sound guide groove 2. The openings of the first sound guide groove 1 and the second sound guide groove 2 face different directions. For example, the first sound guide groove 1 may face the front of the housing 100, and the second sound guide groove 2 may face the rear of the housing 100. Alternatively, the first sound guide groove 1 may face the rear of the housing 100, and the second sound guide groove 2 may face the front of the housing 100. In this embodiment, the example is taken where the first sound guide groove 1 faces the front of the housing 100, and the second sound guide groove 2 faces the rear of the housing 100.
[0091] refer to Figure 3 and combined Figure 2 As shown, both the directional microphone 200 and the omnidirectional microphone 400 are installed inside the housing 100.
[0092] Among them, reference Figure 4 As shown, of the first pickup port 201 and the second pickup port 202, one is connected to the first sound guide groove 1 and the other is connected to the second sound guide groove 2.
[0093] For example, in Figure 4 In one embodiment, the first pickup port 201 may be connected to the first sound guide groove 1, and the second pickup port 202 may be connected to the second sound guide groove 2. However, in other embodiments, the second pickup port 202 may be connected to the first sound guide groove 1, and the first pickup port 201 may be connected to the second sound guide groove 2.
[0094] In this embodiment, as shown Figure 4 Taking the example where the first pickup port 201 is connected to the first sound guide groove 1, and the second pickup port 202 is connected to the second sound guide groove 2. Figure 5 As shown, sound from the front of the housing 100 can be transmitted through the first sound guide 1 to the first pickup port 201 and received by the directional microphone 200. Sound from the rear of the housing 100 can be transmitted through the second sound guide 2 to the second pickup port 202 and received by the directional microphone 200.
[0095] refer to Figure 6 As shown, the third pickup port 401 is connected to either the second sound guide slot 2 or the first sound guide slot 1.
[0096] For example, in Figure 6 In this embodiment, the third pickup port 401 may be connected to the second sound guide groove 2, but in other embodiments, the third pickup port 401 may be connected to the first sound guide groove 1.
[0097] In this embodiment, the third pickup port 401 is connected to the second sound guide slot 2 as an example. Figure 7 As shown, sound from outside the housing 100 can be transmitted through the second sound guide groove 2 to the third pickup port 401 and received by the omnidirectional microphone 400.
[0098] Since the third pickup port 401 of the omnidirectional microphone 400 can simultaneously pick up sound through the second sound guide groove 2 with the second pickup port 202 of the directional microphone 200, the number of ID holes opened on the surface of the housing 100 can be reduced, which is beneficial to improving the aesthetics of the appearance and reducing the difficulty of waterproofing.
[0099] In some possible implementations, refer to Figure 5 and Figure 7 As shown, the pickup assembly also includes at least one of a first pickup channel 203, a second pickup channel 204, and a third pickup channel 205.
[0100] The first pickup port 201 can be connected to the first sound guide groove 1 through the first sound pickup channel 203. Sound from outside the housing 100 can be transmitted to the first pickup port 201 through the first sound guide groove 1 and the first sound pickup channel 203 and received by the directional microphone 200.
[0101] The second pickup port 202 can be connected to the second sound guide groove 2 through the second sound guide channel 204. Sound from outside the housing 100 can be transmitted to the second pickup port 202 through the second sound guide groove 2 and the second sound guide channel 204 and received by the directional microphone 200.
[0102] The third pickup port 401 can be connected to the second sound guide groove 2 through the third sound guide channel 205. Sound from outside the housing 100 can be transmitted sequentially through the second sound guide groove 2 and the third sound guide channel 205 to the third pickup port 401 and received by the omnidirectional microphone 400.
[0103] Therefore, the pickup channel can guide the sound entering the corresponding pickup port from the sound guide slot, which helps to improve the pickup effect of the directional microphone 200 or the omnidirectional microphone 400.
[0104] In some possible implementations, refer to Figure 4 and Figure 6 As shown, the pickup assembly also includes at least one of a first dustproof structure 51, a second dustproof structure 52, and a third dustproof structure 53. The first dustproof structure 51, the second dustproof structure 52, and the third dustproof structure 53 can all be dustproof meshes.
[0105] The first dustproof structure 51 is installed between the first pickup port 201 and the first sound guide groove 1, or within the first pickup port 201. For example, the first dustproof structure 51 can be installed within the first pickup port 201, or as shown in the example. Figure 4 It is installed in the first pickup channel 203 as shown.
[0106] The second dustproof structure 52 is installed between the second pickup port 202 and the second sound guide groove 2, or within the second pickup port 202. For example, the second dustproof structure 52 can be installed within the second pickup port 202, or as shown in the image. Figure 4 It is installed in the second pickup channel 204 as shown.
[0107] The third dustproof structure 53 is installed between the third microphone port 401 and the second sound guide groove 2, or within the third microphone port 401. For example, the third dustproof structure 53 can be installed within the third microphone port 401, or as... Figure 6 It is installed in the first pickup channel 203 as shown.
[0108] The first dustproof structure 51, the second dustproof structure 52 and the third dustproof structure 53 of the pickup assembly can prevent dust from entering the directional microphone 200 and the omnidirectional microphone 400 through the first sound guide groove 1 and the second sound guide groove 2, causing blockage and affecting the pickup effect.
[0109] In some possible implementations, refer to Figure 10As shown, the pickup assembly also includes a printed circuit board 101, which is mounted inside the housing 100.
[0110] The directional microphone 200 and the omnidirectional microphone 400 are mounted on the first side of the printed circuit board 101 and are both electrically connected to the printed circuit board 101. For example, the directional microphone 200 and the omnidirectional microphone 400 can both be fixedly connected to the printed circuit board 101 by means of bolts, screws, etc.
[0111] In this way, both the directional microphone 200 and the omnidirectional microphone 400 of the pickup assembly are connected to the same printed circuit board 101, which helps to improve compactness.
[0112] In some possible implementations, refer to Figure 10 As shown, the housing 100 includes a first half-housing 102 and a second half-housing 103. The first half-housing 102 and the second half-housing 103 together form the housing 100.
[0113] Continue to refer to Figure 10 As shown, at least a portion of the first half-shell 102 is located on the first surface of the printed circuit board 101, and includes a first receiving groove 1021 and a second receiving groove 1022. Both the first receiving groove 1021 and the second receiving groove 1022 cover the first surface of the printed circuit board 101.
[0114] Among them, such as Figure 4 As shown, the directional microphone 200 is located within the first receiving slot 1021, as... Figure 6 As shown, the omnidirectional microphone 400 is located in the second receiving slot 1022.
[0115] Continue to refer to Figure 10 As shown, the second half-shell 103 is attached to the second side of the printed circuit board 101.
[0116] The first sound guide groove 1 is formed on the first half-shell 102, on the second half-shell 103, or between the first half-shell 102 and the second half-shell 103. For example, the first sound guide groove 1 can be formed on the first half-shell 102, on the second half-shell 103, or between the first half-shell 102 and the second half-shell 103.
[0117] The second sound guide groove 2 is formed on the first half-shell 102, on the second half-shell 103, or between the first half-shell 102 and the second half-shell 103. For example, the second sound guide groove 2 can be formed on the first half-shell 102, on the second half-shell 103, or between the first half-shell 102 and the second half-shell 103.
[0118] In this embodiment, as shown Figure 10The first sound guide groove 1 is formed between the first half-shell 102 and the second half-shell 103, and the second sound guide groove 2 is formed on the second half-shell 103, as shown in the example.
[0119] Thus, the first half-shell 102 and the second half-shell 103 of the pickup assembly can clamp and fix the printed circuit board 101, thereby protecting and shielding the directional microphone 200, the omnidirectional microphone 400 and the printed circuit board 101, while facilitating the installation of the microphone on the printed circuit board 101.
[0120] In some possible implementations, Figures 11 to 13 As shown, the inner surface of the housing 100 includes a positioning groove 1033. For example, the positioning groove 1033 may be provided on the inner surface of the second half-housing 103. The bottom of the positioning groove 1033 can fit against the second surface of the printed circuit board 101, and the cross-section of the positioning groove 1033 along the axis perpendicular to the positioning groove 1033 matches the contour of the printed circuit board 101. Thus, the positioning groove 1033 can limit the positioning of the printed circuit board 101, improving the stability of the printed circuit board 101 installation.
[0121] In some possible implementations, refer to Figure 13 As shown, the printed circuit board 101 includes a first through hole 1011 and a second through hole 1012. The second half-shell 103 includes a first connecting groove 1031 and a second connecting groove 1032.
[0122] refer to Figure 6 and Figure 11 As shown, the first connecting groove 1031 and the second connecting groove 1032 are both covered on the second surface of the printed circuit board 101. The first and second surfaces of the printed circuit board 101 are opposite sides of the printed circuit board 101. For example, the first surface of the printed circuit board 101 can be its upper surface, and the second surface can be its lower surface.
[0123] One of the first pickup port 201 and the second pickup port 202 is sequentially connected to the first through hole 1011 and the first connecting groove 1031. For example, in Figure 11 In this case, the second pickup port 202 can be connected to the first through hole 1011 and the first connecting groove 1031 in sequence. However, in other possible examples, the first pickup port 201 can also be connected to the first through hole 1011 and the first connecting groove 1031 in sequence.
[0124] like Figure 6 As shown, the third pickup port 401 is connected to the second through hole 1012 and the second connecting groove 1032 in sequence.
[0125] Furthermore, in order to ensure that the volume of the sound guiding channel between the first sound guide groove 1 and the first pickup port 201 is approximately the same as that between the second pickup port 202 and the second pickup port 202, reference is made accordingly. Figure 11 As shown, of the first sound guide groove 1 and the second sound guide groove 2, one is located on the side of the first surface of the printed circuit board 101 and communicates with the first receiving groove 1021, and the other is located on the side of the second surface of the printed circuit board 101 and communicates with the first connecting groove 1031 and the second connecting groove 1032. This improves the sound pickup effect of the directional microphone 200.
[0126] In some possible implementations, refer to Figure 11 As shown, the housing 100 also includes a first sealing element 104 and a second sealing element 105. Both the first sealing element 104 and the second sealing element 105 can be sealing foam.
[0127] like Figure 11 and Figure 6 As shown, the first seal 104 is installed between the first half-shell 102 and the printed circuit board 101, and covers the opening of the first receiving groove 1021 and the opening of the second receiving groove 1022. For example, the first seal 104 can be sandwiched between the first half-shell 102 and the printed circuit board 101.
[0128] like Figure 13 As shown, the first seal 104 includes a third through hole 1041 and a fourth through hole 1042.
[0129] refer to Figure 11 As shown, one of the first pickup port 201 and the second pickup port 202 is connected to the first through port 1011 through the third through port 1041. For example, in Figure 11 In this embodiment, the second pickup port 202 may be connected to the first through port 1011 through the third through port 1041. However, in other possible embodiments, the first pickup port 201 may also be connected to the first through port 1011 through the third through port 1041.
[0130] refer to Figure 6 As shown, the third pickup port 401 is connected to the second through port 1012 through the fourth through port 1042.
[0131] Continue to refer to Figure 11 As shown, the second seal 105 is installed between the second half-shell 103 and the printed circuit board 101, and as... Figure 11 and Figure 6 As shown, the slots of the first connecting groove 1031 and the second connecting groove 1032 are covered. For example, the second seal 105 can be sandwiched between the second half-shell 103 and the printed circuit board 101.
[0132] Continue to refer to Figure 13 As shown, the second seal 105 includes a fifth through hole 1051 and a sixth through hole 1052. The fifth through hole 1051 is used to connect the first through hole 1011 and the first connecting groove 1031. Wherein, as... Figure 4 and combined Figure 11 As shown, the second dustproof structure 52 can be fixedly installed in the fifth through hole 1051 by adhesive. The sixth through hole 1052 is used to connect the second through hole 1012 and the second connecting groove 1032. Wherein, as... Figure 6 As shown, the third dustproof structure 53 can be fixedly installed in the sixth through hole 1052 by adhesive.
[0133] Therefore, by setting the first seal 104 and the second seal 105, it is beneficial to prevent the sound received by the directional microphone 200 and the omnidirectional microphone 400 from dissipating through the gap between the first half-shell 102 and the printed circuit board 101, and the gap between the second half-shell 103 and the printed circuit board 101, thus affecting the sound quality received by the directional microphone 200 and the omnidirectional microphone 400.
[0134] In a second aspect, an electronic device is provided, the electronic device including a pickup component as described in any of the first aspects.
[0135] The electronic device in this embodiment uses any of the sound pickup components of the first aspect of this utility model, and has all the beneficial effects of any embodiment of the first aspect of this utility model.
[0136] In some possible implementations, refer to Figure 8 and Figure 9 As shown, when the pickup assembly also includes a housing 100, the electronic device also includes a speaker 300, which is installed inside the housing 100. For example, the speaker 300 can be fixedly connected to the housing 100 by bolts, snap-fit, or other means. The speaker 300 includes a first sound-emitting part 301 and a second sound-emitting part 302. The first sound-emitting part 301 communicates with the first sound guide groove 1, and the second sound-emitting part 302 communicates with the second sound guide groove 2.
[0137] For example, the housing 100 may include a first sound-emitting channel 303 and a second sound-emitting channel 304. The first sound-emitting part 301 is connected to the first sound guide groove 1 through the first sound-emitting channel 303, so that the sound emitted by the first sound-emitting part 301 can be transmitted to the outside of the housing 100 through the first sound-emitting channel 303 and the first sound guide groove 1 and be heard by a person. The second sound-emitting part 302 is connected to the second sound guide groove 2 through the second sound-emitting channel 304, so that the sound emitted by the second sound-emitting part 302 can be transmitted to the outside of the housing 100 through the second sound guide groove 2 and be heard by a person.
[0138] Since the first sound guide groove 1 can guide the sound emitted by the first sound-emitting part 301 and the second sound guide groove 2 can guide the sound emitted by the second sound-emitting part 302, the number of ID holes opened on the surface of the housing 100 can be reduced, which is beneficial to improving the ID aesthetics of electronic devices and reducing the stacking space.
[0139] In some possible implementations, refer to Figure 3 and Figure 14 As shown, the first sound guide groove 1 is strip-shaped, the first sound-emitting part 301 is connected to the first sound guide groove 1 near the first end, and the first pickup port 201 is connected to the first sound guide groove 1 near the second end; and / or, the second sound guide groove 2 is strip-shaped, the second sound-emitting part 302 is connected to the second sound guide groove 2 near the first end, and the second pickup port 202 and the third pickup port 401 are both connected to the second sound guide groove 2 near the second end.
[0140] For example, the first sound guide groove 1 can be strip-shaped, or the second sound guide groove 2 can be strip-shaped, or... Figure 1 As shown, both the first sound guide groove 1 and the second sound guide groove 2 are strip-shaped. When the first sound guide groove 1 is strip-shaped, the first sound-emitting part 301 is connected to the first sound guide groove 1 near its first end, and the first pickup port 201 is connected to the first sound guide groove 1 near its second end. When the second sound guide groove 2 is strip-shaped, the second sound-emitting part 302 is connected to the second sound guide groove 2 near its first end, and the second pickup port 202 and the third pickup port 401 are connected to the second sound guide groove 2 near its second end.
[0141] As described above, the first sound guide groove 1 and the second sound guide groove 2 of the electronic device are strip-shaped, allowing for a relatively large distance between the two ends of the first sound guide groove 1 and the two ends of the second sound guide groove 2. The first sound-emitting part 301 is connected to the first sound guide groove 1 near its first end, and the first pickup port 201 is connected to the first sound guide groove 1 near its second end. Therefore, there is no interference between the sound emitted by the first sound-emitting part 301 and the sound received by the first pickup port 201. The second sound-emitting part 302 is connected to the second sound guide groove 2 near its first end, and the second pickup port 202 and the third pickup port 401 are connected to the second sound guide groove 2 near its second end. Therefore, there is no interference between the sound emitted by the second sound-emitting part 302 and the sound received by the second pickup port 202 and the third pickup port 401. Thus, interference between the sound emitted by the speaker 300 and the sound received by the directional microphone 200 and the omnidirectional microphone 400 can be avoided. At the same time, it can also ensure that the first sound guide groove 1 and the second sound guide groove 2 have good concealment while having sufficient sound guide space, which is beneficial to the aesthetics of the ID.
[0142] In some possible implementations, refer to Figures 11 to 13The pickup assembly also includes a housing 100, which includes a first half-housing 102 and a second half-housing 103. The first half-housing 102 includes a first receiving groove 1021 and a second receiving groove 1022.
[0143] refer to Figure 11 As shown, the electronic device includes a screen 1023, a sound guide cover 1024, a middle frame 1034, and a back shell 1035. The screen 1023 and the sound guide cover 1024 form a first half-shell 102, and the middle frame 1034 and the back shell 1035 form a second half-shell 103.
[0144] Continue to refer to Figure 11 As shown, the screen 1023 and the back cover 1035 respectively cover the opposite sides of the mid-frame 1034, and the sound guide cover 1024 is located between the screen 1023 and the mid-frame 1034. For example, the screen 1023, the mid-frame 1034, and the back cover 1035 can be fixedly connected together by adhesive. The sound guide cover 1024 can be fixedly connected to the side of the mid-frame 1034 away from the back cover 1035 by bolts, snap-fit, or other means.
[0145] The first receiving slot 1021 and the second receiving slot 1022 are located on the sound guide cover 1024. The first receiving slot 1021 is used to receive the directional microphone 200, and the second receiving slot 1022 is used to receive the omnidirectional microphone 400.
[0146] For example Figure 10 As shown, a first connecting hole can be formed on one side of the sound guide cover 1024, and a second connecting hole can be formed on the middle frame 1034. The first end of the first connecting hole connects to the first receiving groove 1021, the first end of the second connecting hole connects to the first sound guide groove 1, and the second end of the first connecting hole connects to the second end of the second connecting hole, thus forming a first sound pickup channel 203. Sound from outside the housing 100 can be transmitted to the first receiving groove 1021 via the first sound guide groove 1 and received by the first sound pickup port 201.
[0147] For example Figure 11 As shown, the first receiving groove 1021 and the second receiving groove 1022 can both be formed on the side of the sound guide cover 1024 facing the printed circuit board 101. The positioning groove 1033 can be formed on the side of the middle frame 1034 facing the sound guide cover 1024. The first sealing member 104 can be clamped between the sound guide cover 1024 and the printed circuit board 101, and the sound guide cover 1024 can clamp and limit the first sealing member 104, the printed circuit board 101, and the second sealing member 105.
[0148] For example Figure 11As shown, the side of the middle frame 1034 facing the back shell 1035 can have a first groove that communicates with both the second sound guide groove 2 and the first connecting groove 1031, and the back shell 1035 can cover the middle frame 1034, thus forming the second sound pickup channel 204 together with the fifth through hole 1051, the first through hole 1011 and the third through hole 1041. The second dustproof structure 52 can be installed in the through hole of the third through hole 1041 or the fifth through hole 1051 by means of adhesive or other methods.
[0149] For example Figure 6 As shown, the side of the middle frame 1034 facing the back shell 1035 can have a second groove that communicates with both the second sound guide groove 2 and the second connecting groove 1032, and the back shell 1035 can cover the middle frame 1034, thereby forming a third sound pickup channel 205 together with the sixth through hole 1052, the second through hole 1012 and the fourth through hole 1042. The third dustproof structure 53 can be installed in the fourth through hole 1042 or the sixth through hole 1052 by means of adhesive or other methods.
[0150] Thus, the sound guide cover 1024 accommodates the directional microphone 200 through the first receiving groove 1021 and the omnidirectional microphone 400 through the second receiving groove 1022, thereby protecting and shielding the directional microphone 200 and the omnidirectional microphone 400.
[0151] In some possible implementations, refer to Figure 11 As shown, the electronic device also includes a third seal 106, which can be installed between the guide cover 1024 and the middle frame 1034. Figure 7 As shown, the third seal 106 may be provided with a fourth through hole 1061 for connecting the receiving groove 1021 and the first sound guide groove 1. For example Figure 8 As shown, the third seal 106 can be clamped between the guide cover 1024 and the middle frame 1034, in combination. Figure 7 As shown, the fourth through hole 1061, together with the first connecting hole, the second connecting hole, and the receiving groove 1021, can form the first pickup channel 203. Thus, the third seal 106 helps to prevent the sound received by the directional microphone 200 from dissipating through the gap between the sound guide cover 1024 and the middle frame 1034, thereby affecting the sound quality received by the directional microphone 200 through the first pickup port 201.
[0152] In some possible implementations, when the housing 100 further includes a first sound guide groove 1 and a second sound guide groove 2, one of the first sound guide groove 1 and the second sound guide groove 2 is formed between the screen 1023 and the middle frame 1034, and the other is formed between the back shell 1035 and the middle frame 1034, and the first sound guide groove 1 and the second sound guide groove 2 are located at the same end of the middle frame 1034.
[0153] For example, in Figure 11 In one embodiment, the first sound guide groove 1 may be formed between the screen 1023 and the middle frame 1034, and the second sound guide groove 2 may be formed between the back cover 1035 and the middle frame 1034. However, in other embodiments, the second sound guide groove 2 may be formed between the screen 1023 and the middle frame 1034, and the first sound guide groove 1 may be formed between the back cover 1035 and the middle frame 1034.
[0154] In this way, one of the first sound guide groove 1 and the second sound guide groove 2 of the electronic device is formed between the screen 1023 and the middle frame 1034, and the other is formed between the back shell 1035 and the middle frame 1034. This can reduce the number of ID grooves or holes formed in the shell 100, which is beneficial to the aesthetics of the ID.
