Windproof and dustproof microphone

Abstract

This utility model provides a windproof and dustproof microphone, including a microphone body and a mesh cover installed on the microphone body. The mesh cover includes an annular base, an outer cover, an inner cover, and a lever. The outer cover is fixed on the annular base, and a plurality of mesh holes are arranged in a row on the outer peripheral wall of the outer cover. The inner cover is installed inside the outer cover, and a through hole corresponding to the mesh hole is opened on the inner cover. An annular groove corresponding to the inner cover is opened in the annular base. When the lever is moved to the starting end of the movable hole, the through hole on the inner cover coincides with the mesh hole on the outer cover, so that the mesh cover can pick up sound normally. When the lever is moved to the end of the movable hole, the through hole on the inner cover is offset from the mesh hole on the outer cover, so that the mesh cover is closed, effectively preventing dust, moisture, or foreign objects from entering.

Description

Technical Field

[0001] This utility model relates to the field of microphones, and in particular to a windproof and dustproof microphone. Background Technology

[0002] Microphones, as core devices for sound-to-electric conversion, are widely used in fields such as communication, recording, performing arts, and smart devices. Their mesh structures not only need to ensure high-fidelity sound acquisition, but also need to provide physical protection for sensitive internal components (such as diaphragms and electronic circuits). Traditional microphone meshes mostly adopt a fixed, hollow design. Although they have basic dustproof functions, in long-term use, the porous structure of the fixed mesh cannot effectively prevent dust, moisture, or foreign objects from entering when the equipment is not in use, and it also lacks windproof functions. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned problems in the prior art, this utility model provides a windproof and dustproof microphone.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A windproof and dustproof microphone includes a microphone body and a mesh cover mounted on the microphone body. The mesh cover includes an annular base, an outer cover, an inner cover, and a lever.

[0008] The outer cover is fixed on the annular base, and a number of mesh holes are arranged in a row on the outer peripheral wall of the outer cover.

[0009] The inner cover is installed inside the outer cover, and the inner cover has through holes corresponding to the mesh holes. The annular base has an annular groove corresponding to the inner cover.

[0010] One end of the actuating rod is fixedly connected to the inner cover, and the other end of the actuating rod extends out of the annular base. The annular base has a movable hole corresponding to the actuating rod. When the actuating rod is located at the beginning of the movable hole, the through hole on the inner cover coincides with the mesh hole on the outer cover. When the actuating rod is located at the end of the movable hole, the through hole on the inner cover is offset from the mesh hole on the outer cover.

[0011] Preferably, the top of the outer cover has several sound-receiving holes, and the top of the outer cover can also be detachably fitted with a cover that covers the sound-receiving holes.

[0012] Preferably, the bottom of the cover is provided with a magnetic block, the top of the outer cover is recessed with a magnetic groove, a magnetic metal sheet is provided in the magnetic groove, and the cover is magnetically fixed in the magnetic groove by the magnetic block.

[0014] (III) Beneficial Effects

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Move the lever to the beginning of the movable hole so that the through hole on the inner cover coincides with the mesh on the outer cover, so that the mesh can pick up sound normally. When the lever is moved to the end of the movable hole, the through hole on the inner cover is offset from the mesh on the outer cover, so that the mesh is closed and can effectively prevent dust, moisture or foreign objects from entering.

[0017] 2. When the through holes on the inner cover are offset from the mesh holes on the outer cover, wind noise cannot enter the mesh cover from the side, while the desired recording sound enters the mesh cover through the sound-receiving hole at the top of the mesh cover, which can reduce the interference of outdoor wind and improve the quality of sound recording.

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 3 This utility model provides a windproof and dustproof microphone, including a microphone body 1 and a mesh cover 2 installed on the microphone body 1. The mesh cover 2 includes an annular base 21, an outer cover 22, an inner cover 23, and a lever 24.

[0030] The outer cover 22 is fixed on the annular base 21, and a number of mesh holes are arranged in a row on the outer peripheral wall of the outer cover 22.

[0031] The inner cover 23 is installed inside the outer cover 22, and the inner cover 23 has through holes corresponding to the mesh holes. The annular base 21 has an annular groove corresponding to the inner cover 23.

[0032] One end of the actuating rod 24 is fixedly connected to the inner cover 23, and the other end of the actuating rod 24 extends out of the annular base 21. The annular base 21 has a movable hole corresponding to the actuating rod 24. When the actuating rod 24 is located at the beginning of the movable hole, the through hole on the inner cover 23 coincides with the mesh on the outer cover 22. When the actuating rod 24 is located at the end of the movable hole, the through hole on the inner cover 23 is staggered from the mesh on the outer cover 22.

[0033] In use, move the lever 24 to the beginning of the movable hole so that the through hole on the inner cover 23 coincides with the mesh on the outer cover 22, allowing the mesh cover 2 to pick up sound normally. When the lever 24 is moved to the end of the movable hole, the through hole on the inner cover 23 is offset from the mesh on the outer cover 22, thus closing the mesh cover 2 and effectively preventing dust, moisture or foreign objects from entering.

[0034] In this embodiment, the top of the outer cover 22 is provided with a plurality of sound-receiving holes, and the top of the outer cover 22 can also be detachably fitted with a cover 4, which covers the sound-receiving holes;

[0035] When in use, when the through holes on the inner cover 23 are misaligned with the mesh holes on the outer cover 22, wind noise cannot enter the mesh cover 2 from the side, while the desired recording sound enters the mesh cover 2 through the sound-receiving hole at the top of the mesh cover 2, which can reduce the interference of outdoor wind and improve the quality of sound recording.

[0036] In this embodiment, the bottom of the cover 4 is provided with a magnetic block 5, and the top of the outer cover 22 is recessed with a magnetic groove 3. A magnetic metal sheet is provided in the magnetic groove 3. The cover 4 is magnetically fixed in the magnetic groove 3 by the magnetic block 5. The cover 4 is used to seal the sound-receiving hole at the top of the outer cover 22 and prevent dust, moisture or foreign objects from entering.

[0037] In this embodiment, the inner wall of the annular base 21 is provided with an internal thread, and the microphone body 1 is provided with an external thread. The annular base 21 is threadedly connected to the microphone body 1, so as to realize the detachable installation of the mesh cover 2.

[0038] The working principle of this utility model is as follows:

[0039] Move the lever 24 to the beginning of the movable hole so that the through hole on the inner cover 23 coincides with the mesh on the outer cover 22, allowing the mesh cover 2 to pick up sound normally. When the lever 24 moves to the end of the movable hole, the through hole on the inner cover 23 is offset from the mesh on the outer cover 22, thus closing the mesh cover 2 and effectively preventing dust, moisture or foreign objects from entering.

[0040] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
