Description

Technical Field

[0001] This application belongs to the technical field of headphones, and specifically relates to a type of headphone. Background Technology

[0002] When users use true wireless earbuds in windy environments, the wind noise is significant, which reduces the user experience. Summary of the Invention

[0003] This application aims to provide an earphone that solves one of the problems in the related technology where true wireless earphones have significant wind noise when used in windy environments.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an earphone, comprising: a housing, on which a first steel mesh is provided, the first steel mesh having a plurality of first mesh holes, and a first channel being provided inside the housing; a microphone, disposed inside the housing, the first channel connecting the first steel mesh and the microphone; a second steel mesh, the second steel mesh having a plurality of second mesh holes, the second steel mesh being disposed between the first steel mesh and the first channel; and a driving structure, disposed in the housing, the driving structure being capable of driving the second steel mesh to move, such that the first mesh holes of the first steel mesh and the second mesh holes of the second steel mesh are arranged opposite to each other, or that the first mesh holes and the second mesh holes are arranged alternately.

[0006] In embodiments of this application, the earphone includes a housing, a microphone, a second steel mesh, and a driving structure.

[0007] The housing has a first steel mesh, and the housing has a first channel. The microphone is located inside the housing. The first channel is located between the first mesh and the microphone. The first channel is connected to the first steel mesh and the microphone.

[0008] The driving structure can drive the second steel mesh to move relative to the shell, so that the first mesh opening of the first steel mesh and the second mesh opening of the second steel mesh are arranged opposite each other, or the first mesh opening and the second mesh opening are arranged alternately.

[0009] When the first and second meshes are arranged alternately, the second steel mesh will block part of the first mesh of the first steel mesh. The second mesh and the first mesh can form a boss structure. When the airflow passes through the boss structure, the boss structure can hinder the flow of airflow and reduce the wind speed, thereby reducing the wind noise of the headphones.

[0010] It is understandable that the movement of the second steel mesh relative to the shell can adjust the opening area of ​​the first mesh.

[0011] Optionally, when the user is indoors or outdoors in low wind, the drive structure drives the second steel mesh to move so that the first mesh opening of the first steel mesh and the second mesh opening of the second steel mesh are positioned opposite each other, allowing sound to be transmitted to the microphone.

[0012] Optionally, when the user is in a windy environment, the wind noise captured by the microphone will be relatively loud. The driving structure drives the second steel mesh to move so that the first mesh and the second mesh are arranged alternately to block part of the first mesh. The airflow will first flow through the protrusion structure enclosed by the second mesh and the first mesh, and then flow to the microphone. In this way, the wind speed can be reduced and the wind noise can be reduced.

[0013] Optionally, the drive structure can be made to drive the second steel mesh to adjust the position of the first mesh and the second mesh, depending on the specific actual use requirements.

[0014] This feature allows the headphones to meet the usage needs of different airflow environments, improving their performance and enhancing their market competitiveness.

[0037] The following is combined Figures 1 to 13 The present application describes an earphone 10 according to an embodiment of the present application.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, an earphone 10 according to some embodiments of this application includes: a housing 100, on which a first steel mesh 170 is provided, the first steel mesh 170 having a plurality of first mesh holes 110, and a first channel 120 provided inside the housing 100; a microphone 200, disposed inside the housing 100, the first channel 120 connecting the first steel mesh 170 and the microphone 200; a second steel mesh 300, the second steel mesh 300 having a plurality of second mesh holes 310, the second steel mesh 300 being disposed between the first steel mesh 170 and the first channel 120; and a driving structure 400, disposed in the housing 100, the driving structure 400 being capable of driving the second steel mesh 300 to move, such that the first mesh holes 110 of the first steel mesh 170 and the second mesh holes 310 of the second steel mesh 300 are arranged opposite to each other, or that the first mesh holes 110 and the second mesh holes 310 are arranged alternately.

[0039] In the embodiments of this application, the earphone 10 includes a housing 100, a microphone 200, a second steel mesh 300, and a driving structure 400.

[0040] The housing 100 is provided with a first steel mesh 170 and a first channel 120 is provided inside the housing 100. The microphone 200 is located inside the housing 100. The first channel 120 is located between the first mesh 110 and the microphone 200. The first channel 120 is connected to the first steel mesh 170 and the microphone 200.

[0041] The drive structure 400 can drive the second steel mesh 300 to move relative to the housing 100, so that the first mesh 110 of the first steel mesh 170 and the second mesh 310 of the second steel mesh 300 are arranged opposite each other, or the first mesh 110 and the second mesh 310 are arranged alternately.

[0042] When the first mesh 110 and the second mesh 310 are arranged alternately, the second steel mesh 300 will block part of the first mesh 110 of the first steel mesh 170. The second mesh 310 and the first mesh 110 can form a boss structure. When the airflow passes through the boss structure, the boss structure can hinder the flow of airflow and reduce the wind speed, thereby reducing the wind noise of the headphones 10.

[0043] It is understandable that the movement of the second steel mesh 300 relative to the housing 100 can adjust the opening area of ​​the first mesh 110.

[0044] Optionally, when the user is indoors or outdoors in low wind, the drive structure 400 drives the second steel mesh 300 to move so that the first mesh 110 of the first steel mesh 170 and the second mesh 310 of the second steel mesh 300 are positioned opposite each other, and the sound can be transmitted to the microphone 200.

[0045] Optionally, when the user is in a windy environment, the wind noise captured by the microphone 200 will be relatively loud. The driving structure 400 drives the second steel mesh 300 to move so that the first mesh 110 and the second mesh 310 are arranged alternately to block part of the first mesh 110. The airflow will first flow through the protrusion structure enclosed by the second mesh 310 and the first mesh 110, and then flow to the microphone 200. In this way, the wind speed can be reduced and the wind noise can be reduced.

[0046] Optionally, depending on the specific actual use requirements, the drive structure 400 can drive the second steel mesh 300 to move in order to adjust the position of the first mesh 110 and the second mesh 310.

[0047] This setting enables the headphones 10 to meet the usage needs of different environments with varying airflow, improving the performance of the headphones 10 and enhancing its market competitiveness.

[0048] Optionally, the number of the first mesh 110 is one.

[0049] Optionally, there may be multiple first meshes 110, arranged at intervals. For example, multiple first meshes 110 may form a multi-row, multi-column array structure. For example, multiple first meshes 110 may form a single-row, multi-column array structure. For example, multiple first meshes 110 may form a multi-row, single-column array structure.

[0050] Optionally, when there are multiple first mesh openings 110, the movement of the second steel mesh 300 can adjust the opening area of ​​a portion of the multiple first mesh openings 110.

[0051] Optionally, when there are multiple first mesh openings 110, the movement of the second steel mesh 300 can adjust the opening area of ​​each first mesh opening 110.

[0052] Optionally, the cross-sectional area of ​​the second mesh 310 is greater than or equal to the cross-sectional area of ​​the first mesh 110.

[0053] The drive structure 400 drives the second steel mesh 300 to move relative to the housing 100 to a first position, with the second mesh opening 310 of the second steel mesh 300 positioned opposite to the first mesh opening 110. Since the flow cross-sectional area of ​​the second mesh opening 310 is greater than or equal to the flow cross-sectional area of ​​the first mesh opening 110, the first mesh opening 110 is opened and will not be blocked by the second steel mesh 300.

[0054] The drive structure 400 drives the second steel mesh 300 to move relative to the housing 100 to a second position. The second mesh 310 and the first mesh 110 of the second steel mesh 300 are arranged alternately to block a part of the first mesh 110. A boss structure is formed between the second mesh 310 and the first mesh 110. The boss structure can hinder the flow of air and reduce the wind speed.

[0055] It is understandable that when the second steel mesh 300 is cross-sectioned along the thickness direction perpendicular to the second steel mesh 300, the area enclosed by the outline of the opening wall of the second mesh 310 is the flow cross-sectional area of ​​the second mesh 310.

[0056] It is understandable that when the first steel mesh 170 is cross-sectioned along the thickness direction perpendicular to the first steel mesh 170, the area enclosed by the outline of the opening wall of the first mesh 110 is the flow cross-sectional area of ​​the first mesh 110.

[0057] Optionally, the number of second mesh 310 is one.

[0058] Optionally, there may be multiple second mesh openings 310, which are arranged at intervals. When there are multiple first mesh openings 110 and multiple second mesh openings 310, each first mesh opening 110 is paired with one second mesh opening 310.

[0059] In some other embodiments, the second steel mesh 300 has a baffle, which moves relative to the housing 100 to adjust the position of the baffle and the first mesh 110. When the baffle is located on one side of the first mesh 110, the first mesh 110 is opened. When the baffle is positioned opposite at least a portion of the first mesh 110, at least a portion of the first mesh 110 is blocked by the baffle.

[0060] In some embodiments, such as Figure 3 and Figure 4 As shown, the drive structure 400 includes: a first mating part 410 disposed on the housing 100 and located on one side of the first steel mesh 170; a second mating part 420 located between the first steel mesh 170 and the housing 100 and connected to the second steel mesh 300; when the first mating part 410 is energized, the first mating part 410 drives the second mating part 420 to move toward the first mating part 410, so that the first mesh 110 and the second mesh 310 are arranged alternately.

[0061] In this embodiment, the composition of the drive structure 400 is further defined such that the drive structure 400 includes a first mating part 410 and a second mating part 420, the first mating part 410 and the second mating part 420 are arranged at intervals, and the second mating part 420 is connected to the second steel mesh 300.

[0062] When the first mating part 410 is energized, it can drive the second mating part 420 to move toward the first mating part 410. The movement of the second mating part 420 can drive the second steel mesh 300 to move, so as to adjust the position of the second mesh 310 and the first mesh 110.

[0063] In some embodiments, such as Figure 5 As shown, the earphone 10 also includes: a motherboard 600, which is disposed inside the housing 100. The microphone 200 and the first mating part 410 are both electrically connected to the motherboard 600. The motherboard 600 is used to control the operation of the first mating part 410 according to the detection data of the microphone 200.

[0064] In this embodiment, the structure of the earphone 10 is further defined such that the earphone 10 also includes a motherboard 600, which is electrically connected to the first mating part 410 and to the microphone 200.

[0065] The motherboard 600 can control the operation of the first mating part 410 based on the detection data from the microphone 200. Optionally, the motherboard 600 determines the current ambient airflow based on the detection data from the microphone 200. When the airflow is determined to be low, the motherboard 600 controls the first mating part 410 to be in a de-energized state, so that the first mesh 110 and the second mesh 310 are arranged opposite each other. When the airflow is determined to be high, the motherboard 600 controls the first mating part 410 to be in a energized state, so that the first mesh 110 and the second mesh 310 are arranged alternately.

[0066] In some other embodiments, the earphone 10 also includes a detection element, and a main board 600 is electrically connected to the detection element. The main board 600 can control the operation of the first mating part 410 based on the detection data from the detection element. The detection element is used to check wind noise signals.

[0067] Optionally, microphone 200 is used to detect wind noise signals.

[0068] In some embodiments, such as Figure 4 As shown, the first mating part 410 includes an electromagnet 412, and the second mating part 420 includes a magnet 422.

[0069] In this embodiment, the structures of the first mating part 410 and the second mating part 420 are defined such that the first mating part 410 includes an electromagnet 412 and the second mating part 420 includes a magnet 422.

[0070] When the electromagnet 412 is energized, it can generate a magnetic field to attract the magnet 422 and drive the magnet 422 to move in the direction of the electromagnet 412, thereby driving the second steel mesh 300 to move in the direction of the electromagnet 412, so that the first mesh 110 and the second mesh 310 are arranged alternately.

[0071] When the electromagnet 412 is de-energized, the elastic element 700 drives the magnet 422 to move away from the electromagnet 412, so that the first mesh 110 and the second mesh 310 are positioned opposite each other.

[0072] In some embodiments, such as Figure 13 As shown, the first mating part 410 includes an electro-deformable element 414, and the drive structure 400 also includes a connecting part 470, which connects the electro-deformable element 414 and the second mating part 420.

[0073] In this embodiment, the structures of the first mating part 410 and the second mating part 420 are defined such that the first mating part 410 includes an electro-deformable element 414, and the driving structure 400 further includes a connecting part 470, which connects the electro-deformable element 414 and the second mating part 420.

[0074] When the electro-deformable element 414 is energized, it can deform. The connecting part 470 drives the second mating part 420 to move in the direction of the electro-deformable element 414, thereby driving the second steel mesh 300 to move in the direction of the electro-deformable element 414, so that the first mesh 110 and the second mesh 310 are arranged alternately.

[0075] When the electro-deformable element 414 is de-energized, the elastic element 700 drives the second mating part 420 to move away from the electro-deformable element 414, so that the first mesh 110 and the second mesh 310 are arranged opposite each other.

[0076] Optionally, the electro-deformable component 414 includes shape memory alloy components, graphene components, etc., which will not be listed here.

[0079] The shell body 160 is provided with a first groove 162, and a first steel mesh 170 is disposed in the first groove 162. The first groove 162 serves to accommodate and fix the first steel mesh 170. In this way, the protrusion of the first steel mesh 170 out of the shell 100 can be reduced or even avoided, thus ensuring the streamlined and aesthetically pleasing shape of the earphone 10.

[0080] The first steel mesh 170 has an inner surface and an outer surface. A first chamber 130 is formed between the inner surface of the first steel mesh 170 and the wall of the first groove 162.

[0084] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 12 As shown, the portion of the connecting rod 430 located within the second chamber 140 is provided with a first slot 432, and the portion of the connecting rod 430 located within the first chamber 130 is provided with a second slot 434 and a third slot 436. The drive structure 400 further includes: a first locking plate 440, located in the first slot 432, situated on the side of the second mating part 420 away from the first chamber 130; a second locking plate 450, located in the second slot 434, situated on the outer side of the second steel mesh 300; and a third locking plate 460, located in the third slot 436, situated on the inner side of the second steel mesh 300.

[0085] In this embodiment, the drive structure 400 further includes a first locking plate 440, a second locking plate 450, and a third locking plate 460.

That is, the first locking plate 440 is located within the second chamber 140, and the second locking plate 450 and the third locking plate 460 are both located within the first chamber 130.

[0086] The first locking plate 440 is located on the side of the second mating part 420 away from the first chamber 130. The first locking plate 440 can cooperate with the cavity wall of the second chamber 140 to limit the movement trajectory of the second mating part 420.

[0087] The second clamping plate 450 is located on the outside of the second steel mesh 300, and the third clamping plate 460 is located on the inside of the second steel mesh 300. That is, a part of the second steel mesh 300 is located between the second clamping plate 450 and the third clamping plate 460 to ensure that the connecting rod 430 and the second steel mesh 300 are securely and reliably assembled together.

[0088] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the cavity wall of the second chamber 140 forms a first stop wall 510 and a second stop wall 520; when the second mating part 420 abuts against the first stop wall 510, the first mesh 110 and the second mesh 310 are arranged opposite to each other; when the first clamping plate 440 abuts against the second stop wall 520, the first mesh 110 and the second mesh 310 are arranged alternately.

[0089] In this embodiment, the structure of the shell body 160 is further defined such that the cavity wall of the second chamber 140 forms a first stop wall 510 and a second stop wall 520, the first stop wall 510 and the second stop wall 520 are arranged at intervals, the second mating part 420 can move relative to the second chamber 140, and the cavity wall of the second chamber 140 has the function of limiting the second mating part 420.

[0091] The first stop wall 510 and the second stop wall 520 are used to limit the second mating part 420, thereby indirectly limiting the second steel mesh 300, which can ensure the positional relationship between the second mesh 310 and the first mesh 110.

[0092] It is understood that the second chamber 140 is located between the first chamber 130 and the first mating part 410, and the second mating part 420 is located in the second chamber 140, that is, the second mating part 420 is located between the first mating part 410 and the second steel mesh 300.

[0093] In some embodiments, such as Figure 4 , Figure 6 and Figure 8 As shown, the earphone 10 further includes: an elastic member 700 located in the first chamber 130, the elastic member 700 being sleeved on the connecting rod 430, and the elastic member 700 abutting between the second retaining plate 450 and the cavity wall of the first chamber 130; the elastic member 700 is used to drive the second mating part 420 to move away from the first mating part 410 when the first mating part 410 is in a de-energized state, so that the first mesh 110 and the second mesh 310 are arranged opposite to each other.

[0094] In this embodiment, the earphone 10 further includes an elastic element 700, which is sleeved on the connecting rod 430 and abuts against the cavity wall of the second card plate 450 and the first chamber 130.

[0095] When the first mating part 410 is de-energized, the elastic member 700 can drive the second mating part 420 to move away from the first mating part 410, so as to adjust the position of the second mesh 310 and the first mesh 110, thereby achieving the purpose of the first mesh 110 and the second mesh 310 being arranged relative to each other.

[0096] Optionally, the elastic element 700 includes springs, tension springs, and torsion springs, etc., which will not be listed here.

[0097] Optionally, when the electromagnet 412 is de-energized, the elastic element 700 drives the magnet 422 to move away from the electromagnet 412, so that the first mesh 110 and the second mesh 310 are arranged opposite each other.

[0098] Optionally, when the electro-deformable element 414 is in a de-energized state, the elastic element 700 drives the second mating part 420 to move away from the electro-deformable element 414, so that the first mesh 110 and the second mesh 310 are arranged opposite to each other.

[0099] The elastic element 700 abuts against the cavity wall of the second clamping plate 450 and the first chamber 130. That is, the cavity wall of the second clamping plate 450 and the first chamber 130 support and limit the elastic element 700, providing effective and reliable structural support for driving the second mating part 420 to move away from the first mating part 410 when the first mating part 410 is in a de-energized state.

[0100] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a portion of the outer surface of the first steel mesh 170 is recessed to form a first recess 800, a portion of the groove sidewall of the first groove 162 is recessed to form a second recess 900, and a second chamber 140 is enclosed between the first recess 800 and the second recess 900; the second steel mesh 300 is provided with a second groove 320, the bottom of the groove of the second groove 320 is provided with a second mesh hole 310, and the opening of the second groove 320 faces the first channel 120 and communicates with the first channel 120.

[0101] In this embodiment, a portion of the outer surface of the first steel mesh 170 is recessed to form a first recess 800, and a portion of the groove sidewall of the first groove 162 is recessed to form a second recess 900. The first recess 800 and the second recess 900 enclose a second chamber 140. That is, by making reasonable use of the structure of the first steel mesh 170 and the shell body 160, structural support is provided for the second mating part 420 to move within the second chamber 140 without increasing the external dimensions of the shell body 160.

[0102] The structure of the second steel mesh 300 is further defined such that the second steel mesh 300 is provided with a second groove 320. In other words, the second steel mesh 300 is bent to form a concave structure. The bottom of the groove of the second groove 320 is provided with a second mesh hole 310. The opening of the second groove 320 faces the first channel 120 and is connected to the first channel 120.

[0103] Optionally, the shape of the second steel mesh 300 is adapted to the shape of the first steel mesh 170, that is, the shape of the second steel mesh 300 is the same as the shape of the first steel mesh 170. In this way, the space of the first chamber 130 enclosed between the first steel mesh 170 and the shell body 160 can be effectively utilized.

[0104] Optionally, the shape of the second steel mesh 300 is different from the shape of the first steel mesh 170.

[0105] In some embodiments, such as Figure 1 and Figure 2 As shown, a portion of the shell body 160 is configured as a handle 180, and the handle 180 is provided with a first groove 162.

[0106] In this embodiment, the structure of the housing 100 is further defined such that a portion of the housing body 160 is configured as a handle 180, and the handle 180 is provided with a first groove 162, that is, a first steel mesh 170 is provided on the handle 180.

[0107] In some other embodiments, another portion of the shell body 160 is configured as an earphone body portion 190, with the first steel mesh 170 disposed on the earphone body portion 190.

[0108] Optionally, when the wind speed is relatively high, the position of the second steel mesh 300 can be adjusted so that the first mesh 110 of the first steel mesh 170 and the second mesh 310 of the second steel mesh 300 are arranged alternately to reduce the speed at which the wind enters the first channel 120, thereby reducing wind noise.

[0109] When the user is indoors or outdoors in low wind, the second mesh 310 and the first mesh 110 are set opposite each other, and the sound can be transmitted normally to the microphone 200.

[0110] In windy conditions, the microphone 200 will capture significant wind noise. In this situation, the mainboard 600 will automatically energize the electromagnet 412 to generate a magnetic field that attracts the magnet 422, causing it to move to the right. The magnet 422 is connected to the connecting rod 430, which in turn clamps the second steel mesh 300 via the second and third clamping plates 450 and 460. Therefore, the second steel mesh 300 will also move to the right. This rightward movement creates a slight misalignment between the second mesh opening 310 of the second steel mesh 300 and the first mesh opening 110 of the first steel mesh 170. This creates a protrusion that obstructs the airflow before it enters, reducing wind speed and thus lowering wind noise.

[0111] After the wind stops, the wind noise will be significantly reduced. At this time, the main board 600 will cut off the power to the electromagnet 412. At this time, the elastic element 700 (such as a spring) will release its elastic force, pushing the second steel mesh 300 to the left to return to its original position, and the magnet 422 will also reset along with it.
