Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a sound-generating device and headphones. Background Technology

[0002] Sound-generating devices (such as headphones) act as conversion units, receiving electrical signals from media players or receivers and converting them into audible sound waves using speakers placed close to the ears. With the prevalence of portable electronic devices, sound-generating devices are widely used in mobile phones, portable music players, radios, portable game consoles, and digital audio players. For semi-in-ear sound-generating devices (e.g., semi-in-ear headphones or open-back headphones), when inserted into the ear, dirt and earwax inevitably stick to the sound-generating mesh, causing blockage and affecting sound quality.

[0003] Currently, the sound-generating mesh of sound-generating devices is prone to accumulating dirt and is difficult to clean, affecting the cleanliness and sound effect of the device. Utility Model Content

[0004] The main purpose of this utility model is to propose a sound-generating device and headphones, which aims to solve the technical problem that dirt easily sticks to the sound-generating mesh of current sound-generating devices or headphones, making them difficult to clean and affecting the cleanliness and sound effect of the sound-generating device or headphones.

[0005] To achieve the above objectives, this utility model proposes a sound-generating device, comprising:

[0006] A housing, wherein a sound-emitting hole is provided, and an installation cavity is formed at the sound-emitting hole;

[0007] A nylon mesh is snapped into the mounting cavity, and the nylon mesh completely covers the sound-emitting hole;

[0008] A silicone mesh is disposed on the side of the nylon mesh away from the sound-emitting hole. The silicone mesh is snapped into the mounting cavity and completely covers the nylon mesh.

[0009] In some embodiments, a support is provided around the outer periphery of the silicone mesh in the circumferential direction, and the silicone mesh is connected to the support.

[0010] In some embodiments, the support is a structure made of plastic.

[0011] In some embodiments, the silicone mesh and the support are injection-molded structures.

[0012] In some embodiments, an adhesive layer is provided between the nylon mesh and the silicone mesh, the adhesive layer being used to bond the nylon mesh and the silicone mesh together.

[0013] In some embodiments, the mounting cavity is provided with a mounting groove, and both the nylon mesh and the silicone mesh are snapped into the mounting groove.

[0014] In some embodiments, a first magnetic element is provided in the mounting groove, a second magnetic element is provided on the outer periphery of the nylon mesh, and a third magnetic element is provided on the outer periphery of the silicone mesh;

[0015] The second magnetic component is configured to attract the first magnetic component together to magnetically connect the nylon mesh to the mounting groove; the third magnetic component is configured to attract the first magnetic component together to magnetically connect the silicone mesh to the mounting groove.

[0016] In some embodiments, the thickness D1 of the nylon mesh satisfies: 0.05mm ≤ D1 ≤ 0.1mm.

[0017] In some embodiments, the thickness D2 of the silicone mesh satisfies: 0.4mm ≤ D2 ≤ 0.6mm.

[0018] Correspondingly, this utility model also proposes an earphone, which includes the sound-generating device described in any of the above embodiments.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In the technical solution of this utility model, a nylon mesh and a silicone mesh are sequentially arranged on the outer side of the sound-emitting hole. The nylon mesh and the silicone mesh together form a sound-emitting mesh, which can effectively prevent dirt from entering the sound-emitting hole, thereby ensuring the cleanliness and normal operation of the internal structure of the sound-emitting device and reducing sound attenuation or distortion caused by dirt accumulation. The surface of the silicone mesh is smooth and does not easily stick to dirt. Taking advantage of the above-mentioned properties of the silicone mesh, the silicone mesh is placed on the side of the nylon mesh away from the sound-emitting hole, that is, the silicone mesh is placed on the outermost side. This allows the silicone mesh to effectively block dirt from entering the sound-emitting hole, while facilitating the cleaning of dirt on the silicone mesh, ensuring that the silicone mesh is in a clean state, thereby avoiding the adverse effects of dirt on the internal structure or sound effect of the sound-emitting device. Nylon mesh has excellent waterproof and dustproof properties. Utilizing these properties, the nylon mesh is placed on the side closest to the sound-generating hole, i.e., on the inside. This structure serves two purposes: firstly, because the silicone mesh is placed on the outside of the nylon mesh, it can block most dirt, preventing it from sticking to the nylon mesh (which is more prone to attracting dirt), thus ensuring its cleanliness; secondly, the nylon mesh effectively blocks water vapor or dust, preventing it from entering the sound-generating hole, thereby ensuring the cleanliness of the internal structure of the sound-generating device and avoiding any adverse effects of water vapor or dust on its internal structure or sound effects.

[0021] In this invention, a composite structure composed of nylon mesh and silicone mesh is provided on the outer side of the sound-emitting hole. Utilizing the different properties of the nylon mesh and silicone mesh, it effectively prevents dirt, water vapor, dust, etc., from entering the sound-emitting hole, thereby ensuring the cleanliness and normal operation of the internal structure of the sound-emitting device and extending its service life. Furthermore, the composite structure of nylon mesh and silicone mesh provided by this invention does not easily attract dirt, is easy to clean, and effectively prevents dirt from clogging the sound-emitting hole, thus ensuring the sound quality of the sound-emitting device and avoiding a feeling of blockage when the device is emitting sound.

[0022] The headphones using the aforementioned sound-generating device can effectively prevent dirt from entering the sound-generating hole, thus helping to keep the sound-generating hole clean and extending the service life of the headphones. Attached Figure Description

[0041] Sound-generating devices (such as headphones) act as conversion units, receiving electrical signals from media players or receivers and converting them into audible sound waves using speakers placed close to the ears. With the prevalence of portable electronic devices, sound-generating devices are widely used in mobile phones, portable music players, radios, portable game consoles, and digital audio players. For semi-in-ear sound-generating devices (e.g., semi-in-ear headphones or open-back headphones), when inserted into the ear, dirt and earwax inevitably stick to the sound-generating mesh, causing blockage and affecting sound quality.

[0042] Currently, the sound-generating mesh of sound-generating devices is prone to accumulating dirt and is difficult to clean, affecting the cleanliness and sound effect of the device.

[0043] Therefore, in order to solve the technical problem that dirt easily adheres to the sound-generating mesh of the current sound-generating device 10 or headphones, making it difficult to clean and affecting the cleanliness and sound effect of the sound-generating device 10 or headphones, referring to... Figures 1 to 5This utility model provides a sound-generating device 10, which can be an earphone or the like. The sound-generating device 10 includes a housing 100, a nylon mesh 200, and a silicone mesh 300. The housing 100 has a sound-generating hole 110, and a mounting cavity 120 is formed at the sound-generating hole 110. The nylon mesh 200 is snapped into the mounting cavity 120, completely covering the sound-generating hole 110. The silicone mesh 300 is disposed on the side of the nylon mesh 200 away from the sound-generating hole 110, and is snapped into the mounting cavity 120, completely covering the nylon mesh 200. For example, the mounting cavity 120 has a cavity wall, and the sound-emitting hole 110 can be formed on the cavity wall. In this case, the nylon mesh 200 can abut against the cavity wall, so that the cavity wall provides effective support for the nylon mesh 200, ensuring the positioning stability of the nylon mesh 200, preventing the nylon mesh 200 from shifting, and improving the waterproof and dustproof effect of the nylon mesh 200. Similarly, the silicone mesh 300 can indirectly abut against the cavity wall, so that the cavity wall also provides effective support for the silicone mesh 300, ensuring the positioning stability of the silicone mesh 300, preventing the silicone mesh 300 from shifting, and improving the dirt-proof effect of the silicone mesh 300.

[0044] Specifically, in this embodiment, a nylon mesh 200 and a silicone mesh 300 are sequentially arranged on the outer side of the sound-emitting hole 110. The nylon mesh 200 and the silicone mesh 300 together form a sound-emitting mesh, which can effectively prevent dirt from entering the sound-emitting hole 110, thereby ensuring the cleanliness and normal operation of the internal structure of the sound-emitting device 10 and reducing sound attenuation or distortion caused by dirt accumulation. The surface of the silicone mesh 300 is smooth and does not easily stick to dirt. Taking advantage of the above-mentioned properties of the silicone mesh 300, the silicone mesh 300 is placed on the side of the nylon mesh 200 away from the sound-emitting hole 110, that is, the silicone mesh 300 is placed on the outermost side, so that the silicone mesh 300 can effectively block dirt from entering the sound-emitting hole 110, and at the same time facilitate the cleaning of dirt on the silicone mesh 300, ensuring that the silicone mesh 300 is in a clean state, thereby avoiding the adverse effects of dirt on the internal structure or sound effect of the sound-emitting device 10. The nylon mesh 200 has good waterproof and dustproof properties. Utilizing these properties, the nylon mesh 200 is positioned on the side closest to the sound-emitting hole 110, i.e., on the inner side. With this structure, on the one hand, since the silicone mesh 300 is positioned on the outer side of the nylon mesh 200, it can block most dirt, preventing dirt from sticking to the nylon mesh 200 (compared to the silicone mesh 300, the nylon mesh 200 is more prone to dirt adhesion), thus ensuring the cleanliness of the nylon mesh 200. On the other hand, the nylon mesh 200 can effectively block water vapor or dust, preventing water vapor or dust from entering the sound-emitting hole 110, thereby ensuring the cleanliness of the internal structure of the sound-emitting device 10 and avoiding adverse effects of water vapor or dust on the internal structure or sound effect of the sound-emitting device 10.

[0045] It should be noted that, to improve the waterproof performance of nylon mesh 200, a waterproof coating such as PU (polyurethane), PVC, or silicone can be applied to its surface, allowing the nylon mesh 200 to form a barrier against water vapor. To improve the dustproof performance of nylon mesh 200, the mesh count and density can be increased.

[0046] In this embodiment, a composite structure composed of nylon mesh 200 and silicone mesh 300 is provided on the outer side of the sound-emitting hole 110. Utilizing the different properties of the nylon mesh 200 and silicone mesh 300, dirt, water vapor, dust, etc., can be effectively prevented from entering the sound-emitting hole 110, thereby ensuring the cleanliness and normal operation of the internal structure of the sound-emitting device 10 and extending its service life. Furthermore, the composite structure of nylon mesh 200 and silicone mesh 300 provided in this embodiment is not prone to dirt adhesion, is easy to clean, and can effectively prevent dirt from clogging the sound-emitting hole 110, thereby ensuring the sound effect of the sound-emitting device 10 and avoiding a feeling of blockage when the sound-emitting device 10 is emitting sound.

[0047] In some embodiments, the nylon mesh 200 or silicone mesh 300 may have a plurality of mesh holes evenly and spaced apart, or the nylon mesh 200 or silicone mesh 300 may have mesh holes corresponding to the sound-emitting holes 110. The structural form of the mesh holes on the nylon mesh 200 or silicone mesh 300 is not limited to a single shape. For example, the mesh holes on the nylon mesh 200 or silicone mesh 300 may be circular, elliptical, square, or irregularly shaped. The diameter of the mesh holes on the nylon mesh 200 or silicone mesh 300 should be determined based on whether it obstructs sound transmission and effectively prevents contamination, and can be limited according to actual conditions.

[0048] In some embodiments, refer to Figure 1 , Figure 2 and Figure 5 A support 400 is provided around the circumference of the silicone mesh 300, and the silicone mesh 300 is connected to the support 400. For example, the silicone mesh 300 can be snapped into the support 400, or the silicone mesh 300 and the support 400 can be an integrally molded structure.

[0049] Specifically, in this embodiment, by providing a bracket 400 on the outer periphery of the silicone mesh 300, on the one hand, the bracket 400 can increase the overall structural strength of the silicone mesh 300, improve its impact resistance, and ensure its structural stability; on the other hand, the bracket 400 can provide support for the silicone mesh 300, so as to stably install the silicone mesh 300 in the mounting cavity 120, preventing the silicone mesh 300 from easily falling out of the mounting cavity 120, and ensuring that the silicone mesh 300 can effectively prevent dirt from entering the cavity. Moreover, the bracket 400 can also hold the nylon mesh 200 against the mounting cavity 120, thereby improving the fixing stability of the nylon mesh 200 in the mounting cavity 120, preventing the position of the nylon mesh 200 from shifting, and improving the positioning effect and accuracy of the nylon mesh 200.

[0050] In some embodiments, the bracket 400 is a structure made of plastic. Specifically, in this embodiment, a plastic bracket 400 is used. On the one hand, while maintaining the lightness of the bracket 400, it also provides sufficient strength and toughness, effectively preventing dirt from damaging the bracket 400, thereby improving the durability and service life of the sound-generating device 10. On the other hand, the plastic bracket 400 has good elastic properties and can undergo elastic deformation, which facilitates the installation of the silicone mesh 300 in the mounting cavity 120, reduces the assembly difficulty of the silicone mesh 300, and improves the assembly efficiency of the silicone mesh 300. Furthermore, the plastic bracket 400 has good sealing properties, which can effectively prevent dirt from entering the sound-generating hole 110 from the connection gap, thereby helping to ensure the cleanliness of the sound-generating hole 110.

[0051] In some embodiments, the silicone mesh 300 and the support 400 are injection-molded structures. Specifically, in this embodiment, during actual production, the support 400 can be produced first using a mold. For example, a 5*5 mold can be used to produce 25 supports 400 at once. After all the supports 400 are produced, silicone is injected into each support 400 to form a silicone mesh 300 inside the support 400.

[0052] The silicone mesh 300 and the support 400 adopt an injection molding structure. On the one hand, this helps to improve the connection stability between the silicone mesh 300 and the support 400, ensuring that the silicone mesh 300 and the support 400 are an integral structure. On the other hand, it facilitates the mass production of the composite structure composed of the silicone mesh 300 and the support 400, allowing multiple composite structures composed of silicone mesh 300 and support 400 to be produced at the same time, thereby saving time costs and improving processing efficiency when producing composite structures composed of silicone mesh 300 and support 400.

[0053] In some embodiments, an adhesive layer is provided between the nylon mesh 200 and the silicone mesh 300 to bond the nylon mesh 200 and the silicone mesh 300 together. For example, the adhesive layer can be glue, meaning the nylon mesh 200 and the silicone mesh 300 are bonded together with glue. Alternatively, the adhesive layer can also be double-sided tape, meaning the nylon mesh 200 and the silicone mesh 300 are bonded together with double-sided tape.

[0054] Specifically, in this embodiment, the nylon mesh 200 and silicone mesh 300 are bonded together by an adhesive layer, which helps to improve the structural integrity between the nylon mesh 200 and silicone mesh 300, as well as the connection strength between them. When assembling the sound-generating device 10, only the composite structure composed of the nylon mesh 200 and silicone mesh 300 needs to be installed in the mounting cavity 120, instead of installing the nylon mesh 200 and silicone mesh 300 separately in the mounting cavity 120. This simplifies the assembly process of the sound-generating device 10, improves its assembly efficiency, and reduces its assembly difficulty.

[0055] In some embodiments, refer to Figure 3 and Figure 4 The mounting cavity 120 is provided with a mounting groove 121, in which the nylon mesh 200 and silicone mesh 300 are both snapped into the mounting groove 121. Specifically, in this embodiment, by snapping the nylon mesh 200 and silicone mesh 300 into the mounting groove 121, the connection stability of the nylon mesh 200 and silicone mesh 300 at the sound-emitting hole 110 is improved, preventing the nylon mesh 200 and silicone mesh 300 from easily falling off and thus failing to effectively block dirt.

[0056] In some embodiments, a first magnetic element is disposed within the mounting groove 121, a second magnetic element is disposed around the outer periphery of the nylon mesh 200, and a third magnetic element is disposed around the outer periphery of the silicone mesh 300. For example, the mounting groove 121 may have a full circle of first magnetic elements arranged circumferentially, corresponding to the first magnetic elements, the outer periphery of the nylon mesh 200 may have a full circle of second magnetic elements, and the outer periphery of the silicone mesh 300 may have a full circle of third magnetic elements. Alternatively, the mounting groove 121 may have multiple first magnetic elements spaced apart circumferentially, corresponding to the first magnetic elements, the outer periphery of the nylon mesh 200 may have multiple second magnetic elements spaced apart, and the outer periphery of the silicone mesh 300 may have multiple third magnetic elements spaced apart. The second magnetic elements are configured to attract the first magnetic elements to magnetically connect the nylon mesh 200 to the mounting groove 121; the third magnetic elements are configured to attract the first magnetic elements to magnetically connect the silicone mesh 300 to the mounting groove 121.

[0057] Specifically, in this embodiment, when the nylon mesh 200 approaches the mounting groove 121, it will automatically install itself into the mounting groove 121 under the magnetic attraction of the second and first magnetic components. Similarly, when the silicone mesh 300 approaches the mounting groove 121, it will automatically install itself into the mounting groove 121 under the magnetic attraction of the third and first magnetic components. This structure reduces the assembly difficulty of the nylon mesh 200 and silicone mesh 300 within the mounting groove 121, improves the connection efficiency and accuracy of the nylon mesh 200 and silicone mesh 300 within the mounting groove 121, and enhances the connection stability of the nylon mesh 200 and silicone mesh 300 within the mounting groove 121.

[0058] In some embodiments, the thickness D1 of the nylon mesh 200 satisfies: 0.05mm ≤ D1 ≤ 0.1mm. For example, the value of D1 can be 0.05mm, 0.07mm, 0.09mm, 0.1mm, etc.

[0059] Specifically, in this embodiment, the thickness of the nylon mesh 200 is set within the aforementioned range. On the one hand, this ensures the effective waterproofing and dustproofing of the nylon mesh 200, preventing it from being too thin and thus reducing its waterproofing and dustproofing effect (for example, the value of D1 is 0.01mm, 0.02mm, 0.03mm, 0.04mm, etc.). As the thickness of the nylon mesh 200 increases, its waterproofing and dustproofing effect also improves accordingly, thereby enhancing the anti-fouling performance of the sound-generating device 10. On the other hand, this ensures the sound-generating effect of the sound-generating device 10, preventing the nylon mesh 200 from being too thick and affecting its sound generation (for example, the value of D1 is 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc.), which could cause a feeling of blockage when the sound-generating device 10 is emitting sound. At the same time, setting the thickness of the nylon mesh 200 appropriately helps to save on the manufacturing materials of the sound-generating device 10 and reduce the manufacturing cost of the sound-generating device 10.

[0060] In some embodiments, the thickness D2 of the silicone mesh 300 satisfies: 0.4mm ≤ D2 ≤ 0.6mm. For example, the value of D2 can be 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, etc.

[0061] Specifically, in this embodiment, the thickness of the silicone mesh 300 is set within the aforementioned range. On the one hand, this ensures the effective protection against dirt by the silicone mesh 300, preventing it from becoming too thin and reducing its dirt-resistant effect (for example, the value of D2 is 0.1mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, etc.). As the thickness of the silicone mesh 300 increases, its dirt-resistant effect also improves, thereby enhancing the anti-fouling performance of the sound-generating device 10. On the other hand, this ensures the sound-generating effect of the sound-generating device 10, preventing the silicone mesh 300 from becoming too thick and affecting its sound production (for example, the value of D2 is 0.7mm, 0.75mm, 0.8mm, 0.9mm, 1mm, etc.), which could cause a feeling of blockage when the sound-generating device 10 is producing sound. Furthermore, setting the thickness of the silicone mesh 300 appropriately helps save on the manufacturing materials of the sound-generating device 10, reducing its manufacturing cost.

[0062] Correspondingly, another embodiment of the present invention also provides an earphone, which can be an open-back earphone or a semi-in-ear earphone, and the earphone includes the sound-generating device 10 in any of the above embodiments.

[0063] Specifically, in this embodiment, the earphone using the above-mentioned sound-generating device 10 can effectively prevent dirt from entering the sound-generating hole 110 of the earphone, which helps to keep the sound-generating hole 110 of the earphone clean and extend the service life of the earphone.

[0064] Thanks to the improvements to the sound-generating device 10 described above, the headphones of this embodiment have the same technical effects as the sound-generating device 10 described above, which will not be repeated here.

[0065] It should be noted that other contents of the sound-generating device 10 and headphones disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0066] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
