Description

Technical Field

[0001] This utility model relates to a silicon microphone with a protective shell that is easy to connect to, and belongs to the field of silicon microphone technology. Background Technology

[0002] Silicon microphones are primarily based on capacitive sensor technology. A thin diaphragm in the silicon structure vibrates with sound, generating changing capacitance. The second plate of the capacitor lies on a fixed surface within the silicon. A charge pump in the IC generates a high DC voltage for the capacitor, and the IC circuitry converts this capacitance change into an electrical signal representing the audio signal on the MEMS diaphragm. All microphones initially transmit analog audio signals. These weak signals need to be amplified by a preamplifier, and then converted into analog or digital signals by integrated specialized circuitry.

[0003] Chinese Patent Publication No. (CN 216565592 U) discloses a silicon microphone with an easily mated protective shell, comprising: a circuit board, an amplifier disposed on the surface of the circuit board, a silicon microphone chip disposed on the side of the circuit board near the amplifier, and a protective shell body disposed on the top of the circuit board, wherein the circuit board, amplifier, silicon microphone chip, and protective shell body constitute the basic components of the silicon microphone; a mating seat disposed on the outer side of the circuit board near the amplifier and silicon microphone chip, wherein a mating groove is formed on the inner wall of the bottom end of the protective shell body, and a welding strip is disposed on the outer side of the protective shell body. This silicon microphone with an easily mated protective shell utilizes a mating groove, a mating seat, and welding strips to prevent misalignment during mating, thus facilitating the mating of the silicon microphone with the protective shell. Combined with a mounting base and guide holes, sound is emitted from both sides, thereby preventing dust from entering the silicon microphone through the sound holes.

[0004] However, traditional silicon microphones are not convenient to connect to protective shells. Their structure is complex, operation is troublesome, and they are not efficient to use. The connection and installation are difficult and inconvenient for staff to operate.

[0005] To address this, a silicon microphone that is easy to connect to a protective housing is proposed. Utility Model Content

[0006] In view of this, the present invention provides a silicon microphone that is easy to connect to a protective shell, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A silicon microphone with a protective shell that is easy to connect to includes a protective sleeve. The microphone body is movably connected inside the protective sleeve. A positioning mechanism is provided on the outer side of the protective sleeve. The positioning mechanism includes a plug rod, a movable plate, a tension spring, and a rotating rod. The inner side of the rotating rod contacts the outer side of the protective sleeve. The movable plate is threadedly connected to the surface of the rotating rod. The inner side of the tension spring is fixedly connected to the outer side of the protective sleeve. The outer side of the tension spring is fixedly connected to the inner side of the movable plate. The outer side of the plug rod is fixedly connected to the inner side of the movable plate. The inner side of the plug rod extends through the protective sleeve into the interior of the microphone body.

[0008] More preferably, a fixing groove is provided on the outer side of the microphone body, and the inner side of the plug is movably connected to the inside of the fixing groove.

[0009] More preferably, the outer side of the rotating rod is threaded, and the thread on the surface of the rotating rod meshes with the inner thread of the moving plate.

[0010] More preferably, the top of the protective sleeve is provided with a connecting groove, and a dustproof net is movably connected to the inside of the connecting groove by bolts.

[0011] More preferably, the inner side of the protective sleeve is provided with a compression groove, and a clamping mechanism is provided inside the compression groove. The clamping mechanism includes a compression spring and a clamping block. The outer side of the compression spring is fixedly connected to the inside of the compression groove, and the outer side of the clamping block is fixedly connected to the inside of the compression spring.

[0012] More preferably, the surface of the extrusion groove is provided with a sliding groove, and a limiting rod is fixedly connected to the outside of the clamping block, with the outside of the limiting rod movably connected to the inside of the extrusion groove.

[0013] More preferably, a protective pad is fixedly connected to the inner side of the clamping block, and the inner side of the protective pad is in contact with the surface of the microphone body.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model uses a positioning mechanism to rotate the rotating rod during microphone body installation. The rotating rod drives the moving plate to move, and the moving plate drives the insertion rod to pass through the inside of the fixing groove, so that the microphone body is stably fixed inside the protective sleeve to prevent loosening and detachment. By setting threads, the direction of movement of the moving plate is ensured when the rotating rod is rotated.

[0016] II. In this utility model, the clamping mechanism allows the clamping block to move when the microphone body is installed. The compression spring pushes the clamping block to move, so that the protective pad contacts the surface of the microphone body, increasing the friction between the pad and the surface of the microphone body. By setting a sliding groove, the clamping block moves along the movement trajectory provided by the sliding groove, ensuring that the clamping block moves along the movement trajectory.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-4 As shown, this utility model embodiment provides a silicon microphone with a convenient protective shell, including a protective sleeve 1. The microphone body 2 is movably connected inside the protective sleeve 1. A positioning mechanism 3 is provided on the outer side of the protective sleeve 1. The positioning mechanism 3 includes a plug rod 301, a movable plate 302, a tension spring 303, and a rotating rod 304. The inner side of the rotating rod 304 contacts the outer side of the protective sleeve 1. The movable plate 302 is threaded 5 to the surface of the rotating rod 304. The inner side of the tension spring 303 is fixedly connected to the outer side of the protective sleeve 1, and the outer side of the tension spring 303 is fixedly connected to the inner side of the movable plate 302. The outer side of the plug rod 301 is fixedly connected to the inner side of the movable plate 302. The inner side of the plug rod 301 extends through the protective sleeve 1 into the interior of the microphone body 2. A fixing groove 4 is provided on the outer side of the microphone body 2. The inner side of the plug rod 301 is movably connected to the interior of the fixing groove 4. A thread 5 is provided on the outer side of the rotating rod 304. The thread 5 on the surface of the rotating rod 304 meshes with the thread 5 on the inner side of the movable plate 302.

[0030] When installing the microphone body 2, the rotating rod 304 is rotated via the positioning mechanism 3. The rotating rod drives the moving plate 302 to move. When the moving plate 302 drives the insertion rod 301 to move, the insertion rod 301 passes through the inside of the fixing groove 4, so that the microphone body 2 is stably fixed inside the protective sleeve 1 to prevent loosening and detachment. By setting the thread 5, the moving direction of the moving plate 302 is ensured when the rotating rod 304 is rotated.

[0031] Example 2

[0032] like Figure 5-6As shown, in one embodiment, the top of the protective sleeve 1 is provided with a connecting groove 6, and a dustproof mesh 7 is movably connected to the inside of the connecting groove 6 by bolts. The inner side of the protective sleeve 1 is provided with a compression groove 8, and a clamping mechanism 9 is provided inside the compression groove 8. The clamping mechanism 9 includes a compression spring 901 and a clamping block 902. The outer side of the compression spring 901 is fixedly connected to the inside of the compression groove 8, and the outer side of the clamping block 902 is fixedly connected to the inside of the compression spring 901. A sliding groove 10 is provided on the surface of the compression groove 8. A limiting rod 11 is fixedly connected to the outer side of the clamping block 902, and the outer side of the limiting rod 11 is movably connected to the inside of the compression groove 8. A protective pad 12 is fixedly connected to the inner side of the clamping block 902, and the inner side of the protective pad 12 is in contact with the surface of the microphone body 2.

[0033] When installing the microphone body 2, the clamping mechanism 9 uses the spring 901 to push the clamping block 902 to move, so that the protective pad 12 contacts the surface of the microphone body 2, increasing the friction with the surface of the microphone body 2. By setting the sliding groove 10, the clamping block 902 moves according to the moving trajectory provided by the sliding groove 10, ensuring that the clamping block 902 moves along the moving trajectory.

[0034] When this utility model is in operation: First, rotate the rotating rod 304. The rotating rod drives the moving plate 302 to move outward. The moving plate 302 drives the insertion rod 301 to move outward while stretching the tension spring 303. At this time, the microphone body 2 can be installed. After that, rotate the rotating rod 304 in the opposite direction. The rotating rod 304 drives the moving plate 302 to move inward. The moving plate 302 pushes the insertion rod 301 and inserts it into the fixing groove 4 to fix the microphone body 2. The spring force of the compression spring 901 pushes the clamping block 902 to move inward at the same time, increasing the friction on the surface of the microphone body 2.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
