Description

Technical Field

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

[0002] Many electronic devices have internal acoustic devices such as speakers and microphones, and have interconnected sound guide channels and sound holes on their casings. 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 achieve sound transmission. Alternatively, the sound generated by the acoustic devices is guided through the sound guide channels to the sound holes and then discharged through the sound holes to achieve sound production.

[0003] In related technologies, double-layer dustproof meshes are installed at intervals within the sound guide channel. These meshes filter out oil, dust, and other contaminants, preventing external contaminants from clogging the sound holes and the sound guide channel, thus ensuring the acoustic performance of the acoustic components. Specifically, the mesh size of the dustproof mesh near the sound holes is larger, while the mesh size of the mesh further away from the sound holes is smaller. This allows the dustproof mesh near the sound holes to filter larger particles of oil, dust, and other contaminants, while the mesh further away from the sound holes filters smaller particles of oil, dust, and other contaminants.

[0004] However, oil stains in dirt have a strong adhesion ability. When oil stains adhere to the dustproof mesh far away from the sound hole, over time, the mesh holes of the dustproof mesh far away from the sound hole will be blocked, which in turn will block the sound guiding channel and affect the acoustic performance of the acoustic device. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device that can solve the problem that the sound channel of electronic devices in related technologies is easily blocked.

[0006] This application provides an electronic device, including a device housing, an acoustic device, a first filter, and a second filter. The acoustic device is disposed within the device housing. The device housing has a sound guiding channel and a sound hole. A first end of the sound guiding channel is opposite to the acoustic device, and a second end of the sound guiding channel communicates with the sound hole. Along the sound intake direction of the sound guiding channel, the first filter and the second filter are disposed alternately within the sound guiding channel.

[0007] The first filter screen is opposite to the sound hole, and the first filter screen is provided with a first blocking area. Along the sound guiding direction of the sound guiding channel, at least a portion of the orthographic projection of the sound hole is located within the orthographic projection of the first blocking area.

[0008] In this embodiment, oil and other contaminants entering the sound channel through the sound hole will enter the sound channel along the direction of the axis of the sound hole. Since at least a portion of the orthographic projection of the sound hole is located within the orthographic projection of the first blocking area, at least a portion of the oil and other contaminants entering through the sound hole can fall directly into the first blocking area, preventing these contaminants from passing through the first filter screen and falling into the second filter screen, thereby preventing blockage of the mesh of the second filter screen and preventing the sound channel from being blocked, which is beneficial to ensuring the acoustic performance of the acoustic device.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] Please refer to Figures 1-10 The electronic device disclosed in this application includes a device housing 100, an acoustic device 200, a first filter 300, and a second filter 400. 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 inside 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 out dirt such as oil and dust.

[0030] The acoustic device 200 is disposed within the device housing 100. Optionally, the acoustic device 200 and the device housing 100 can be connected by welding, bonding, or other methods. The device housing 100 is provided with a sound guiding channel 100a and a sound hole 100b. The sound guiding channel 100a is used to guide sound signals, and the sound hole 100b is used for sound input and output. (See reference...) Figure 3 As shown, the first end of the sound guiding channel 100a is opposite to the acoustic device 200, and the second end of the sound guiding channel 100a is connected to the sound hole 100b. With this configuration, the sound signal emitted by the acoustic device 200 can be discharged through the sound guiding channel 100a and finally discharged through the sound hole 100b, or, external sound signals can enter the sound guiding channel 100a through the sound hole 100b and be collected by the acoustic device 200.

[0031] Optionally, there can be multiple sound holes 100b, which together form a sound inlet area or a sound outlet area. The sound holes 100b can be square holes, circular holes, etc., and the specific shape of the sound holes 100b is not limited in this embodiment. The sound guide channel 100a can be a bent channel or a straight channel, etc., and the specific structure of the sound guide channel 100a is not limited in this embodiment.

[0032] Along the sound inlet direction of the sound guide channel 100a, a first filter 300 and a second filter 400 are spaced apart within the sound guide channel 100a. That is, the first filter 300 is closer to the sound hole 100b, and the second filter 400 is farther from the sound hole 100b, located on the side of the first filter 300 away from the sound hole 100b. Optionally, the edges of the first filter 300 and the second filter 400 are connected to the device housing 100 by welding, bonding, or other methods. Thus, both the sound signal and the gas flowing along the sound guide channel 100a must pass through the first filter 300 and the second filter 400.

[0033] The first filter screen 300 is opposite to the sound hole 100b. Thus, gas, oil, and other contaminants entering through the sound hole 100b must first pass through the first filter screen 300. Furthermore, the first filter screen 300 has a first blocking region 310, which has no mesh openings. Therefore, gas, oil, and other contaminants cannot pass through the first blocking region 310. Along the sound guiding direction of the sound guiding channel 100a, at least a portion of the orthographic projection of the sound hole 100b lies within the orthographic projection of the first blocking region 310. The sound guiding direction of the sound guiding channel 100a can be either an inlet direction or an outlet direction, with the inlet direction being opposite to the outlet direction.

[0034] Optionally, refer to Figure 5 As shown, along the sound guiding direction of the sound channel 100a, a portion of the orthographic projection of the sound hole 100b lies within the orthographic projection of the first blocking region 310; or, referring to... Figure 9 and Figure 10 As shown, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the sound hole 100b is entirely located within the orthographic projection of the first blocking area 310.

[0035] In this embodiment, oil and other contaminants entering the sound channel 100a through the sound hole 100b will enter the sound channel 100a along the direction of the axis of the sound hole 100b. Since at least a portion of the orthographic projection of the sound hole 100b is located within the orthographic projection of the first blocking region 310, at least a portion of the oil and other contaminants entering through the sound hole 100b can fall directly into the first blocking region 310, preventing these contaminants from passing through the first filter screen 300 and falling into the second filter screen 400, thereby preventing blockage of the mesh of the second filter screen 400 and preventing the sound channel 100a from being blocked, which is beneficial to ensuring the acoustic performance of the acoustic device 200.

[0036] In the scheme of this application, reference is made to Figures 3-6 As shown, the first filter 300 has a first air-permeable area 320, which is adjacent to the first blocking area 310. The second filter 400 has a second blocking area 410, which is opposite to the first air-permeable area 320. Specifically, the portion of the first filter 300 with perforations forms the first air-permeable area 320, and the portion of the first filter 300 without perforations forms the first blocking area 310; the portion of the second filter 400 without perforations forms the second blocking area 410.

[0037] refer to Figure 5 As shown, the sound hole 100b includes a first part 101b and a second part 102b. Along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the first part 101b is located within the orthographic projection of the first blocking region 310, and the orthographic projection of the second part 102b is located within the orthographic projection of the first ventilating region 320. Moreover, at least a portion of the orthographic projection of the second part 102b is located within the orthographic projection of the second blocking region 410. That is to say, of the dust, oil, and other substances entering through the sound hole 100b, a portion falls directly into the first blocking region 310, and another portion passes directly through the first ventilating region 320. At least a portion of the dust, oil, and other substances passing through the first ventilating region 320 falls into the second blocking region 410.

[0038] Optionally, along the sound guiding direction of the sound guiding channel 100a, a portion of the orthographic projection of the second part 102b lies within the orthographic projection of the second sealing area 410, so that a portion of the dust, oil, etc., passing through the first ventilated area 320 falls into the second sealing 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 sealing area 410. Thus, all dust, oil, and other substances passing through the first ventilated area 320 fall into the second sealing area 410.

[0039] Optionally, refer to Figure 1 and Figure 2As shown, the device housing 100 includes a frame 110, and a sound hole 100b can be disposed in the frame 110.

[0040] In this embodiment, a portion of the oil and other contaminants entering through the sound hole 100b fall directly into the first sealing area 310, while another portion of the contaminants fall into the second sealing area 410 through the first filter screen 300. This prevents the contaminants from falling into the air-permeable area of ​​the second filter screen 400, thereby preventing blockage of the mesh of the second filter screen 400 and preventing the sound guiding channel 100a from being blocked, which is beneficial to further improving the acoustic performance of the acoustic device 200.

[0041] Of course, in other embodiments, the second filter 400 is provided with a second breathable area 420, only the second breathable area 420 is opposite to the first breathable 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 breathable area 420.

[0042] In one optional embodiment, along the sound guiding direction of the sound guiding channel 100a, a portion of the orthographic projection of the first ventilated area 320 lies within the orthographic projection of the second blocking area 410, while another portion of the orthographic projection of the first ventilated area 320 lies outside the orthographic projection of the second blocking area 410.

[0043] In another embodiment, combined Figure 4 and Figure 6 As shown, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the first venting area 320 lies within the orthographic projection of the second sealing area 410. This arrangement ensures that all oil and other contaminants passing through the first filter 300 fall into the second sealing area 410, preventing them from falling outside the second sealing area 410. This effectively prevents the mesh of the second filter 400 from becoming clogged and the sound guiding channel 100a from being blocked, further improving the acoustic performance of the acoustic device 200.

[0044] In one optional embodiment, the second filter 400 is provided with a second ventilated area 420, which is offset from the first ventilated area 320. Along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second ventilated area 420 is outside the orthographic projection of the first blocking area 310. Moreover, a part of the orthographic projection of the second blocking area 410 is 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.

[0045] In another embodiment, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second ventilated area 420 lies within the orthographic projection of the first blocking area 310, and the orthographic projection of the second blocking area 410 lies outside the orthographic projection of the first blocking area 310. That is, the orthographic projection of the second blocking area 410 and the orthographic projection of the first blocking area 310 have no overlapping area, and the orthographic projection of the second ventilated area 420 coincides with the orthographic projection of the first blocking area 310.

[0046] In this embodiment, the orthographic projection of the second blocking area 410 does not coincide with the orthographic projection of the first blocking area 310. Therefore, oil and other contaminants passing through the first filter screen 300 can fall into various positions of the second blocking area 410, avoiding the overlap between the orthographic projection of the second blocking area 410 and the orthographic projection of the first blocking area 310, which would prevent some areas of the second blocking area 410 from being unable to receive contaminants. Based on this, the orthographic projection of the second ventilated area 420 coincides with the orthographic projection of the first blocking area 310, which helps to increase the second ventilated area 420 and effectively prevents the mesh of the second filter screen 400 from being blocked.

[0047] In this embodiment, reference Figure 6 As shown, when the electronic device outputs sound, the sound signal enters the sound guide channel 100a through the sound hole 100b, changes its propagation path after passing through the first venting area 320, and further passes through the second venting area 420 before reaching the acoustic device 200; Reference Figure 5 As shown, when the electronic device emits sound, the sound signal emitted by the acoustic device 200 enters the sound guide channel 100a, changes its propagation path after passing through the second venting area 420, and then flows out through the sound hole 100b after passing through the first venting area 320.

[0048] In the scheme of this application, reference is made to Figure 9 and Figure 10 As shown, along the sound inlet direction of the sound guide channel 100a, the orthographic projection of the sound hole 100b lies within the orthographic projection of the first blocking region 310. That is, all oil and other contaminants entering through the sound hole 100b can fall into the first blocking region 310, thus the second filter 400 does not need to collect contaminants. The first filter 300 has a first ventilated region 320, and the second filter 400 has a second ventilated region 420, which is opposite to the first ventilated region 320.

[0049] refer to Figure 10 As shown, dust and other contaminants entering the sound guiding channel 100a through the sound hole 100b fall into the first sealing area 310. The sound signal enters the sound guiding channel 100a through the sound hole 100b, changes its propagation path, and then passes through the first ventilated area 320 and the second ventilated area 420 before reaching the acoustic device 200. (Reference) Figure 9As shown, when the electronic device emits sound, the sound signal emitted by the acoustic device 200 enters the sound guide channel 100a, passes through the second venting area 420 and the first venting area 320 in sequence, changes the propagation path, and finally flows out through the sound hole 100b.

[0050] 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 disposed within the space surrounded by the decorative ring 120. The decorative cover 130 is connected to the decorative ring 120, and a sound hole 100b is formed in the decorative cover 130. Further optionally, the decorative ring 120 and the decorative cover 130 can be connected by welding, bonding, or other methods.

[0051] In this embodiment, the first sealing area 310 receives all dust, oil and other contaminants entering through the sound hole 100b. The second filter screen 400 does not need to have a second sealing area 410 to receive contaminants, which helps to increase the air permeability area of ​​the second filter screen 400 and effectively prevents the mesh of the second filter screen 400 from being blocked.

[0052] In an optional embodiment, the sound holes 100b are arranged in a ring array, and the first blocking region 310 surrounds the first venting region 320. Optionally, the sound holes 100b can be evenly or unevenly distributed along the ring array direction; the sound holes 100b can be arranged in a square ring array, and the first blocking region 310 is a square ring region; or, the sound holes 100b can be arranged in a circular ring array, and the first blocking region 310 is a circular ring region.

[0053] In this embodiment, the sound signal entering through the sound hole 100b can enter the first ventilated area 320 from all directions, or the sound signal generated by the acoustic device 200 can be dispersed to the surroundings after passing through the first ventilated 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.

[0054] Of course, in other embodiments, the sound hole 100b can also be arranged in other arrays, and the first blocking area 310 can be an arc-shaped area, a square area, etc., and the first blocking area 310 can be adjacent to the first ventilating area 320.

[0055] In one optional embodiment, along the sound guiding direction of the sound guiding channel 100a, a portion of the orthographic projection of the second breathable region 420 lies within the orthographic projection of the first breathable region 320, and another portion of the orthographic projection of the second breathable region 420 lies outside the orthographic projection of the first breathable region 320.

[0056] In another embodiment, along the sound guiding direction of the sound guiding channel 100a, the orthographic projection of the second breathable region 420 lies within the orthographic projection of the first breathable region 320. That is, the orthographic projection of the second breathable region 420 coincides with the orthographic projection of the first breathable region 320, so that the first breathable region 320 and the second breathable region 420 are completely opposite to each other.

[0057] In this embodiment, external sound signals can pass smoothly through the first ventilated area 320 and various positions of the second ventilated area 420, and then reach the acoustic device 200. Alternatively, the sound signals generated by the acoustic device 200 can pass smoothly through the first ventilated area 320 after passing through the second ventilated area 420, and then flow out through the sound hole 100b, thus successfully producing sound.

[0058] In one optional embodiment, along the sound guiding direction of the sound guiding channel 100a, the area of ​​the orthographic projection of the first breathable area 320 is not equal to the area of ​​the orthographic projection of the second breathable area 420. It can be that the area of ​​the orthographic projection of the first breathable area 320 is greater than the area of ​​the orthographic projection of the second breathable area 420, or it can be that the area of ​​the orthographic projection of the first breathable area 320 is less than the area of ​​the orthographic projection of the second breathable area 420.

[0059] In another 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 equal to the area of ​​the orthographic projection of the second breathable region 420. Optionally, the orthographic projections of the first breathable region 320 and the second breathable region 420 have the same shape and size, thereby achieving equal orthographic projection areas.

[0060] In this embodiment, the air permeability area of ​​the first filter screen 300 is equal to that of the second filter screen 400, which is beneficial to improving the sound transmission efficiency and gas exchange efficiency.

[0061] In this embodiment, the first filter screen 300 is provided with a plurality of first mesh holes located in the first air-permeable area 320, and the second filter screen 400 is provided with a plurality of second mesh holes 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.

[0062] Optionally, refer to Figures 1-6As shown, the sound hole 100b is disposed in the frame 110. The first filter screen 300 is provided with a first ventilated area 320 and a first blocking area 310. The second filter screen 400 is provided with a second ventilated area 420 and a second blocking area 410. The first ventilated area 320 is opposite to the second blocking area 410, and the second ventilated area 420 is opposite to the first blocking area 310. The area of ​​the first ventilated area 320 is equal to the area of ​​the second ventilated area 420, and the area of ​​the first blocking area 310 is equal to the area of ​​the second blocking area 410. Therefore, the ventilated area of ​​the first filter screen 300 and the second filter screen 400 is half of the flow area. Since the area of ​​the sound hole 100b is usually less than or equal to half of the flow area of ​​the sound guiding channel 100a, the area of ​​the sound hole 100b can be made to be equal to the ventilated area of ​​the first filter screen 300 and the second filter screen 400, thus avoiding affecting the sound transmission efficiency and gas exchange efficiency.

[0063] Optionally, refer to Figures 7-10 As shown, the sound hole 100b is opened on the decorative cover 130. The first filter screen 300 is provided with a first ventilation area 320 and a first blocking area 310. The second filter screen 400 is provided with a second ventilation area 420. The first ventilation area 320 and the second ventilation area 420 are opposite to each other. The area of ​​the first ventilation area 320 is equal to the area of ​​the second ventilation area 420.

[0064] With this configuration, regardless of where the sound hole 100b is located in the device housing 100, by setting a first blocking area 310 on the first filter screen 300, the first blocking area 310 receives at least part of the dirt entering through the sound hole 100b, preventing this part of the oil and dirt from falling into the second filter screen 400 through the first mesh, thereby preventing the second mesh from being blocked and preventing the sound guiding channel 100a from being blocked, which helps to ensure the acoustic performance of the acoustic device 200.

[0065] In the scheme of this application, reference is made to Figure 9 and Figure 10 As shown, the electronic device also includes a support member 500, which is disposed within the device housing 100. At least one of the first filter screen 300 and the second filter screen 400 is connected to the support member 500. The support member 500 is located on the side of the first filter screen 300 that faces away from the sound hole 100b. The support member 500 is provided with a collection groove 510, which is opposite to the first blocking area 310. That is, the collection groove 510 faces the first blocking area 310.

[0066] Optionally, the support member 500 and the equipment housing 100 can be fixedly connected by welding, bonding or other methods; the support member 500 can be connected only to the first filter screen 300, or only to the second filter screen 400, or simultaneously to both the first filter screen 300 and the second filter screen 400, and the connection method is not limited to welding, bonding or other methods.

[0067] In this embodiment, the support member 500 supports at least one of the first filter screen 300 and the second filter screen 400. Moreover, the collection tank 510 is opposite to the first blocking area 310, so oil and other dirt falling into the first blocking area 310 can further fall into the collection tank 510. The collection tank 510 reduces the amount of dirt stored in the first blocking area 310, which helps more dust and other dirt to fall into the first blocking area 310, further preventing dust and other dirt from blocking the mesh of the first filter screen 300.

[0068] Of course, in other embodiments, the support member 500 may not be provided with a collection groove 510, and the first filter screen 300 may be provided in a detachable installation manner, and the first filter screen 300 may be periodically removed to treat the dirt in the first blockage area 310.

[0069] In one alternative embodiment, the number of support members 500 is one.

[0070] In another embodiment, reference Figure 9 and Figure 10 As shown, at least two support members 500 are spaced apart along the direction extending from the first blocking area 310, and each support member 500 is provided with a collection groove 510. Optionally, each support member 500 may be provided with one collection groove 510 or multiple collection grooves 510. The structures of each support member 500 may be the same, and similarly, the structures of the collection grooves 510 of each support member 500 may be different.

[0071] Optionally, the first blocking area 310 is an annular area, and at least two support members 500 are provided at intervals along the circumference of the first blocking area 310.

[0072] In this embodiment, the number of support members 500 increases, which is more conducive to supporting at least one of the first filter screen 300 and the second filter screen 400; the number of collection tanks 510 increases, the total collection volume of the collection tanks 510 increases, and the amount of dirt distributed by the collection tanks 510 increases, which is conducive to more dust and other dirt falling into the first sealing area 310, further preventing dust and other dirt from blocking the mesh of the first filter screen 300.

[0073] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices, video game consoles, etc. This application does not limit the specific types of electronic devices.

[0074] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
