Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0002] Many electronic devices are equipped with acoustic devices such as speakers and microphones, and interconnected sound guide channels and sound holes are opened on the shell of the electronic device. The sound guide channels are opposite to the acoustic devices. In this way, external sound enters the sound guide channels through the sound holes and then reaches the acoustic devices to realize sound input. Alternatively, the sound generated by the acoustic devices is guided to the sound holes through the sound guide channels and discharged from the sound holes to realize sound generation.

[0003] In the related art, double-layer dust-proof nets are arranged at intervals in the sound guide channel, and the dust-proof nets are used to filter out dirt such as oil and dust, so as to prevent dirt outside the electronic device from blocking the sound hole and the sound guide channel, thereby ensuring the acoustic performance of the acoustic device. Specifically, the mesh of the dust-proof net near the sound hole in the sound guide channel is larger, and the mesh of the dust-proof net far from the sound hole is smaller. In this way, the dust-proof net near the sound hole filters out dirt such as oil and dust with larger particles, and the dust-proof net far from the sound hole filters out dirt such as oil and dust with smaller particles.

[0004] However, the oil in the dirt has a strong adhesion ability. When the oil adheres to the dust-proof net far away from the sound hole, over time, the mesh holes of the dust-proof net far away from the sound hole are blocked, which in turn causes the sound guide channel to be blocked, affecting the acoustic performance of the acoustic device. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that the sound guide channel of the electronic device is easily blocked.

[0006] An embodiment of the present application provides an electronic device, including a device housing, an acoustic device, a first filter and a second filter, wherein the acoustic device is disposed in the device housing, the device housing is provided with a sound guide channel and a sound hole, a first end of the sound guide channel is opposite to the acoustic device, a second end of the sound guide channel is connected to the sound hole, and along the sound input direction of the sound guide channel, the first filter and the second filter are disposed in the sound guide channel at intervals; The first filter is opposite to the sound hole, and the first filter is provided with a first blocking area, and along the sound guiding direction of the sound guiding channel, at least part of the orthographic projection of the sound hole is located within the orthographic projection of the first blocking area.

[0007] In the embodiment of the present application, oil and other substances entering the sound guide channel through the sound hole will enter the sound guide channel along the direction of the axis of the sound hole. Since at least part of the orthographic projection of the sound hole is located within the orthographic projection of the first blocking area, at least part of the oil and other substances entering through the sound hole can directly fall into the first blocking area, preventing this part of the oil and other substances from passing through the first filter and falling into the second filter, thereby avoiding clogging the mesh of the second filter and preventing the sound guide channel from being blocked, which is beneficial to ensuring the acoustic performance of the acoustic device.

[0012] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-Figure 10 The electronic device disclosed in the embodiment of the present application includes a device housing 100, an acoustic device 200, a first filter 300 and a second filter 400, wherein the device housing 100 serves as the main component of the electronic device, and the acoustic device 200, the first filter 300 and the second filter 400 are all installed in the device housing 100; the acoustic device 200 can be a speaker, a microphone, etc.; the first filter 300 and the second filter 400 are used to filter oil, dust and other impurities.

[0014] The acoustic device 200 is disposed in the device housing 100. Optionally, the acoustic device 200 and the device housing 100 can be connected by welding, bonding, etc. The device housing 100 is provided with a sound guide channel 100a and a sound hole 100b. The sound guide channel 100a is used to guide the sound signal, and the sound hole 100b is used to input and output the sound. Figure 3 As shown, the first end of the sound guide channel 100a is opposite to the acoustic device 200, and the second end of the sound guide channel 100a is connected to the sound hole 100b. In this way, the sound signal emitted by the acoustic device 200 can be discharged from the sound hole 100b through the sound guide channel 100a, or the external sound signal enters the sound guide channel 100a through the sound hole 100b and is collected by the acoustic device 200.

[0015] Optionally, the number of the sound holes 100b can be multiple, and the multiple sound holes 100b form a sound inlet area or a sound outlet area. The sound hole 100b can be a square hole, a circular hole, etc., and the embodiment of the present application does not limit the specific shape of the sound hole 100b; the sound guide channel 100a can be a curved channel or a linear channel, etc., and the embodiment of the present application does not limit the specific structure of the sound guide channel 100a.

[0016] Along the sound input direction of the sound guide channel 100a, the first filter 300 and the second filter 400 are arranged at intervals in the sound guide channel 100a. That is to say, the first filter 300 is closer to the sound hole 100b, the second filter 400 is farther away from the sound hole 100b, and the second filter 400 is located on the side of the first filter 300 away from the sound hole 100b. Optionally, the edge of the first filter 300 and the edge of the second filter 400 are respectively connected to the device housing 100 by welding, bonding, etc. In this way, the sound signal and gas flowing along the sound guide channel 100a need to pass through the first filter 300 and the second filter 400.

[0017] The first filter 300 is opposite to the sound hole 100b, so that the gas, oil and other objects entering from the sound hole 100b need to first pass through the filtering effect of the first filter 300. In addition, the first filter 300 is provided with a first blocking area 310, and the first blocking area 310 has no mesh, so the first blocking area 310 cannot pass through the gas, oil and other objects. Along the sound guiding direction of the sound guiding channel 100a, at least part of the orthographic projection of the sound hole 100b is located in the orthographic projection of the first blocking area 310. Among them, the sound guiding direction of the sound guiding channel 100a can be the sound input direction or the sound output direction, and the sound input direction is opposite to the sound output direction.

[0018] Optionally, refer to Figure 5 As shown, along the sound guiding direction of the sound guiding channel 100a, a part of the orthographic projection of the sound hole 100b is located within the orthographic projection of the first blocking area 310; or, with reference to Fig. 9 and Fig.10 As shown, along the sound guiding direction of the sound guiding channel 100 a , the orthographic projections of the sound holes 100 b are all located within the orthographic projection of the first blocking area 310 .

[0019] In the embodiment of the present application, oil and other substances entering the sound guide channel 100a through the sound hole 100b will enter the sound guide channel 100a along the direction of the axis of the sound hole 100b. Since at least part of the orthographic projection of the sound hole 100b is located within the orthographic projection of the first blocking area 310, at least part of the oil and other substances entering through the sound hole 100b can directly fall into the first blocking area 310, thereby preventing this part of the oil and other substances from passing through the first filter 300 and falling into the second filter 400, thereby avoiding clogging the mesh of the second filter 400 and preventing the sound guide channel 100a from being blocked, which is beneficial to ensuring the acoustic performance of the acoustic device 200.

[0020] In the scheme of this application, reference is made to Figure 3-Figure 6 As shown, the first filter net 300 is provided with a first air permeable area 320, and the first air permeable area 320 is arranged adjacent to the first blocking area 310, and the second filter net 400 is provided with a second blocking area 410, and the second blocking area 410 is opposite to the first air permeable area 320. Specifically, the part of the first filter net 300 provided with meshes forms the first air permeable area 320, and the part of the first filter net 300 not provided with meshes forms the first blocking area 310; the part of the second filter net 400 not provided with meshes forms the second blocking area 410.

[0021] refer to Figure 5 As shown, the sound hole 100b includes a first portion 101b and a second portion 102b. Along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the first portion 101b is located within the orthographic projection of the first blocking area 310, the orthographic projection of the second portion 102b is located within the orthographic projection of the first air permeable area 320, and at least part of the orthographic projection of the second portion 102b is located within the orthographic projection of the second blocking area 410. In other words, among the dust, oil and other objects entering through the sound hole 100b, a part directly falls into the first blocking area 310, and another part directly passes through the first air permeable area 320, and at least part of the dust, oil and other objects passing through the first air permeable area 320 falls into the second blocking area 410.

[0022] Optionally, along the sound guiding direction of the sound guiding channel 100a, a part of the orthographic projection of the second portion 102b is located within the orthographic projection of the second blocking area 410, so that a part of the dust, oil, etc. passing through the first air permeable area 320 falls on the second blocking area 410; or, refer to Figure 4 As shown, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second part 102b is located within the orthographic projection of the second blocking area 410 , so that dust, oil stains and the like passing through the first breathable area 320 all fall into the second blocking area 410 .

[0023] Optionally, refer to Figure 1 and Figure 2As shown, the device housing 100 includes a frame body 110 , and the sound hole 100 b can be disposed in the frame body 110 .

[0024] By adopting this embodiment, a part of the oil and other dirt entering through the sound hole 100b directly falls into the first blocking area 310, and another part of the dirt falls into the second blocking area 410 through the first filter net 300, thereby preventing this part of the dirt from falling into the breathable area of ​​the second filter net 400, thereby avoiding clogging the mesh of the second filter net 400 and avoiding blocking of the sound guide channel 100a, which is beneficial to further improve the acoustic performance of the acoustic device 200.

[0025] Of course, in other embodiments, the second filter 400 is provided with a second air permeable area 420 , and only the second air permeable area 420 is opposite to the first air permeable area 320 , and along the sound guiding direction of the sound guiding channel 100a , the orthographic projection of the second part 102b is located within the orthographic projection of the second air permeable area 420 .

[0026] In an optional embodiment, along the sound guiding direction of the sound guiding channel 100a, a portion of the orthographic projection of the first breathable area 320 is located within the orthographic projection of the second blocking area 410, and another portion of the orthographic projection of the first breathable area 320 is located outside the orthographic projection of the second blocking area 410.

[0027] In another embodiment, in combination Figure 4 and Figure 6 As shown, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the first air permeable area 320 is located within the orthographic projection of the second blocking area 410. With such a configuration, all dirt such as oil that passes through the first filter 300 can fall into the second blocking area 410, preventing dirt such as oil that passes through the first filter 300 from falling into a position outside the second blocking area 410, and more effectively preventing the mesh of the second filter 400 from being blocked and preventing the sound guiding channel 100a from being blocked, which is beneficial to further improving the acoustic performance of the acoustic device 200.

[0028] In an optional embodiment, the second filter 400 is provided with a second air permeable area 420, and the second air permeable area 420 is staggered with the first air permeable area 320. Along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second air permeable area 420 is located outside the orthographic projection of the first blocking area 310, and a part of the orthographic projection of the second blocking area 410 is located outside the orthographic projection of the first blocking area 310, and another part of the orthographic projection of the second blocking area 410 coincides with the orthographic projection of the first blocking area 310.

[0029] In another embodiment, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second air permeable area 420 is located within the orthographic projection of the first blocking area 310, and the orthographic projection of the second blocking area 410 is located outside the orthographic projection of the first blocking area 310. In other words, the orthographic projection of the second blocking area 410 has no overlapping area with the orthographic projection of the first blocking area 310, and the orthographic projection of the second air permeable area 420 overlaps with the orthographic projection of the first blocking area 310.

[0030] With this embodiment, the orthographic projection of the second blocking area 410 does not overlap with the orthographic projection of the first blocking area 310, so that oil stains and other dirt passing through the first filter 300 can fall into various positions of the second blocking area 410, avoiding the partial orthographic projection of the second blocking area 410 overlapping with the orthographic projection of the first blocking area 310, which causes the local area of ​​the second blocking area 410 to be unable to receive dirt. Based on this, the orthographic projection of the second breathable area 420 overlaps with the orthographic projection of the first blocking area 310, which is conducive to increasing the second breathable area 420 and effectively preventing the mesh of the second filter 400 from being blocked.

[0031] In this embodiment, reference Figure 6 As shown, when the electronic device receives sound, the sound signal enters the sound guide channel 100a from the sound hole 100b, changes the propagation path after passing through the first air permeable area 320, and further reaches the acoustic device 200 after passing through the second air permeable area 420; Figure 5 As shown, when the electronic device produces sound, the sound signal emitted by the acoustic device 200 enters the sound guide channel 100a, changes the propagation path after passing through the second air permeable area 420, and further passes through the first air permeable area 320 before flowing out from the sound hole 100b.

[0032] In the scheme of this application, reference is made to Fig. 9 and Fig.10 As shown, along the sound input direction of the sound guide channel 100a, the orthographic projection of the sound hole 100b is located within the orthographic projection of the first blocking area 310. In other words, all dirt such as oil entering from the sound hole 100b can fall into the first blocking area 310, so the second filter 400 does not need to receive dirt. The first filter 300 is provided with a first air permeable area 320, and the second filter 400 is provided with a second air permeable area 420, and the second air permeable area 420 is opposite to the first air permeable area 320.

[0033] refer to Fig.10 As shown, dust and other dirt entering the sound guide channel 100a from the sound hole 100b falls into the first blocking area 310, and the sound signal enters the sound guide channel 100a from the sound hole 100b, changes the propagation path, and then passes through the first air permeable area 320 and the second air permeable area 420 in sequence before reaching the acoustic device 200; refer to Fig. 9As shown, when the electronic device produces sound, the sound signal emitted by the acoustic device 200 enters the sound guide channel 100a, passes through the second air permeable area 420 and the first air permeable area 320 in sequence, changes the propagation path, and finally flows out from the sound hole 100b.

[0034] Optionally, refer to Figure 7 and Figure 8 As shown, the device housing 100 includes a decorative ring 120 and a decorative cover 130, the camera of the electronic device is arranged in the space surrounded by the decorative ring 120, the decorative cover 130 is connected to the decorative ring 120, and the sound hole 100b is opened in the decorative cover 130. Further optionally, the decorative ring 120 and the decorative cover 130 can be connected by welding, bonding, etc.

[0035] With this embodiment, the first blocking area 310 receives all dust, oil and other dirt entering through the sound hole 100b, and the second filter 400 does not need to be provided with a second blocking area 410 to receive the dirt, which is beneficial to increasing the air permeability area of ​​the second filter 400 and effectively preventing the mesh of the second filter 400 from being blocked.

[0036] In an optional embodiment, the sound holes 100b are distributed in an annular array, and the first blocking area 310 is arranged around the first ventilated area 320. Optionally, along the annular array direction, the sound holes 100b can be evenly distributed or unevenly distributed; the sound holes 100b can be distributed in a square annular array, and the first blocking area 310 is a square annular area, or the sound holes 100b can be distributed in a circular annular array, and the first blocking area 310 is a circular annular area.

[0037] With this embodiment, the sound signal entering through the sound hole 100b can enter the first breathable area 320 from all directions, or the sound signal generated by the acoustic device 200 is dispersed to the surroundings after passing through the first breathable area 320 and can be dispersed from the sound hole 100b from all directions, which is beneficial to improving the acoustic performance of the electronic device.

[0038] Of course, in other embodiments, the sound holes 100 b may also be distributed in other arrays, and the first blocking area 310 may be an arc-shaped area, a square area, etc., and the first blocking area 310 and the first breathable area 320 may be adjacent.

[0039] In an optional embodiment, along the sound guiding direction of the sound guiding channel 100a, a portion of the orthographic projection of the second breathable area 420 is located within the orthographic projection of the first breathable area 320, and another portion of the orthographic projection of the second breathable area 420 is located outside the orthographic projection of the first breathable area 320.

[0040] In another embodiment, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second air permeable area 420 is located within the orthographic projection of the first air permeable area 320. In other words, the orthographic projection of the second air permeable area 420 coincides with the orthographic projection of the first air permeable area 320, so that the first air permeable area 320 and the second air permeable area 420 are completely opposite.

[0041] By adopting this embodiment, the external sound signal can smoothly pass through various positions of the second breathable area 420 through the first breathable area 320, and then reach the acoustic device 200, or the sound signal generated by the acoustic device 200 can smoothly pass through the first breathable area 320 after passing through the second breathable area 420, and then flow out from the sound hole 100b, thereby successfully achieving sound production.

[0042] In an optional embodiment, along the sound guiding direction of the sound guiding channel 100a, the area of ​​the orthographic projection of the first breathable region 320 is not equal to the area of ​​the orthographic projection of the second breathable region 420. The area of ​​the orthographic projection of the first breathable region 320 may be larger than the area of ​​the orthographic projection of the second breathable region 420, or the area of ​​the orthographic projection of the first breathable region 320 may be smaller than the area of ​​the orthographic projection of the second breathable region 420.

[0043] In another embodiment, along the sound guiding direction of the sound guiding channel 100a, the area of ​​the orthographic projection of the first air permeable area 320 is equal to the area of ​​the orthographic projection of the second air permeable area 420. Optionally, the orthographic projection of the first air permeable area 320 and the orthographic projection of the second air permeable area 420 are the same in shape and size, so that the orthographic projection areas of the two are equal.

[0044] According to this embodiment, the air permeability area of ​​the first filter 300 is equal to the air permeability area of ​​the second filter 400, which is beneficial to improving the sound transmission efficiency and the gas exchange efficiency.

[0045] In this embodiment, the first filter 300 is provided with a plurality of first mesh holes, which are located in the first air permeable area 320, the second filter 400 is provided with a plurality of second mesh holes, which are located in the second air permeable area 420, and the flow area of ​​each first mesh hole is greater than the flow area of ​​each second mesh hole.

[0046] Optionally, refer to Figure 1-Figure 6As shown, the sound hole 100b is arranged in the frame 110, the first filter 300 is provided with a first air permeable area 320 and a first blocking area 310, the second filter 400 is provided with a second air permeable area 420 and a second blocking area 410, the first air permeable area 320 is opposite to the second blocking area 410, the second air permeable area 420 is opposite to the first blocking area 310, the area of ​​the first air permeable area 320 is equal to the area of ​​the second air permeable area 420, the area of ​​the first blocking area 310 is equal to the area of ​​the second blocking area 410, so the air permeable area of ​​the first filter 300 and the second filter 400 is half of the flow area, and usually the area of ​​the sound hole 100b is less than or equal to half of the flow area of ​​the sound guide channel 100a, so the area of ​​the sound hole 100b can be equal to the air permeable area of ​​the first filter 300 and the second filter 400, so as to avoid affecting the sound transmission efficiency and gas exchange efficiency.

[0047] Optionally, refer to Figure 7-10 As shown, the sound hole 100b is opened in the decorative cover 130, the first filter 300 is provided with a first air permeable area 320 and a first blocking area 310, the second filter 400 is provided with a second air permeable area 420, the first air permeable area 320 is opposite to the second air permeable area 420, and the area of ​​the first air permeable area 320 is equal to the area of ​​the second air permeable area 420.

[0048] In this way, no matter where the sound hole 100b is opened in the device housing 100, by setting the first blocking area 310 on the first filter 300, the first blocking area 310 receives at least part of the dirt entering through the sound hole 100b, thereby preventing this part of the oil from passing through the first mesh and falling into the second filter 400, thereby avoiding clogging the second mesh and preventing the sound guide channel 100a from being blocked, which is beneficial to ensuring the acoustic performance of the acoustic device 200.

[0049] In the scheme of this application, reference is made to Fig. 9 and Fig.10 As shown, the electronic device also includes a supporting member 500, which is arranged in the device housing 100, and at least one of the first filter 300 and the second filter 400 is connected to the supporting member 500, and the supporting member 500 is located on the side of the first filter 300 facing away from the sound hole 100b, and the supporting member 500 is provided with a collecting groove 510, which is opposite to the first blocking area 310, that is, the collecting groove 510 faces the first blocking area 310.

[0050] Optionally, the support member 500 can be fixedly connected to the equipment housing 100 by welding, bonding, etc.; the support member 500 can be connected only to the first filter screen 300, or only to the second filter screen 400, or can be connected to the first filter screen 300 and the second filter screen 400 at the same time, and the connection method is not limited to welding, bonding, etc.

[0051] In this embodiment, the supporting member 500 supports at least one of the first filter 300 and the second filter 400, and the collecting groove 510 is opposite to the first blocking area 310, so that oil and other dirt falling on the first blocking area 310 can further fall into the collecting groove 510. The amount of dirt stored in the first blocking area 310 is shared by the collecting groove 510, which is conducive to more dust and other dirt falling into the first blocking area 310, and further avoiding dust and other dirt blocking the mesh of the first filter 300.
