Technical Field

[0001] This utility model relates to the field of microphone capsule technology, and in particular to a moisture-proof microphone capsule. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. It is the input terminal of a sound device, as opposed to a speaker (output terminal). Microphones are also known as microphones, microphones, and transducers.

[0003] When microphones are not in use, they are usually placed aside. When placed in a humid environment, they are easily infiltrated by moisture. In existing technology, moisture will adhere to the internal components of the microphone, resulting in deterioration of sound quality, such as noise and distortion. Long-term exposure to a humid environment may also cause short circuits in the internal circuits of the microphone, shortening its lifespan, increasing usage costs and maintenance frequency, and making it less practical. Therefore, a moisture-proof microphone needs to be redesigned to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a moisture-proof microphone capsule.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A moisture-proof microphone head includes a microphone head body and a mounting plate. A protective frame that mates with the microphone head body is slidably mounted on the upper surface of the mounting plate. Connecting frames are fixedly mounted on both outer walls of the protective frame. Connecting plates are fixedly mounted inside each of the two connecting frames. The outer walls of the two connecting plates are fixedly connected to the outer wall of the microphone head body. Fixing pins are slidably installed through the outer walls of the two connecting frames. Insertion holes that mate with the fixing pins on the same side are opened on the outer walls of the two connecting plates. A lever is fixedly mounted at the end of each of the two fixing pins. The inner walls of the two levers are connected to the outer walls of the connecting frames through a fixing mechanism. A moisture-absorbing plate is slidably mounted on the inner wall of the protective frame through the mounting mechanism. Two fixing plates are fixedly mounted on both outer walls of the protective frame. A connecting block is fixedly mounted between the two fixing plates through a rotating mechanism. A protective cover is fixedly mounted on the upper surface of the connecting block through the connecting mechanism. A sealing gasket is fixedly mounted on the bottom wall of the protective cover. A sealing groove that mates with the sealing gasket is opened on the upper surface of the protective frame. A handle is fixedly mounted on the upper surface of the protective cover.

[0007] The fixing mechanism includes a fixing spring installed on the outer wall of the fixing pin, and the two ends of the fixing spring are elastically connected to the inner wall of the lever block and the outer wall of the connecting frame, respectively.

[0008] The installation mechanism includes an installation frame that is fixedly installed on the inner wall of the protective frame, and the moisture-absorbing plate is slidably installed inside the installation frame.

[0009] The rotating mechanism includes a rotating rod rotatably mounted between two fixed plates, and the connecting block is fixedly mounted on the outer wall of the rotating rod.

[0010] The connecting mechanism includes a connecting rod fixedly installed on the outer wall of the connecting block, and the end of the connecting rod is fixedly connected to the outer wall of the protective cover.

[0011] An installation opening is provided on the upper surface of the protective cover, and an observation glass is fixedly installed inside the installation opening.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a protective frame, moisture-absorbing plate, protective cover, and sealing gasket, the protective frame tightly wraps around the microphone body to prevent moisture from seeping in. The moisture-absorbing plate can absorb a small amount of moisture that enters and provide long-lasting moisture protection. The protective cover rotates around the handle and its sealing gasket fits tightly with the sealing groove of the protective frame, further isolating moisture. This can achieve all-round and multi-layered moisture protection for the microphone body, improving the microphone's working stability and service life in humid environments.

[0014] 2. By setting up components such as fixing pins, levers, and fixing springs, the lever can be moved to disengage or engage the fixing pins in the connector plate socket, making it easy to disassemble and install the microphone body and the protective frame. After installation, under the action of the fixing spring, the fixing pins automatically engage in the socket to achieve a stable connection, so that the protective frame tightly wraps around the microphone body, effectively blocking external moisture from directly contacting it and providing reliable protection for the microphone body.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A moisture-proof microphone head includes a microphone head body 1 and a mounting plate 2. A protective frame 3 that mates with the microphone head body 1 is slidably mounted on the upper surface of the mounting plate 2. Connecting frames 4 are fixedly mounted on both outer walls of the protective frame 3. Connecting plates 5 are fixedly mounted inside the two connecting frames 4. The outer walls of the two connecting plates 5 are fixedly connected to the outer wall of the microphone head body 1. Fixing pins 6 are slidably installed through the outer walls of the two connecting frames 4. Insertion holes that mate with the fixing pins 6 on the same side are opened on the outer walls of the two connecting plates 5. A lever 7 is fixedly mounted at the end of the two fixing pins 6. The inner walls of the two levers 7 are fixed by a fixing... The mechanism is connected to the outer wall of the connecting frame 4. The fixing mechanism includes a fixing spring 8 installed on the outer wall of the fixing pin 6. The two ends of the fixing spring 8 are elastically connected to the inner wall of the lever block 7 and the outer wall of the connecting frame 4, respectively. The inner wall of the protective frame 3 is slidably installed with a moisture-absorbing plate 10 through the installation mechanism. The main material of the moisture-absorbing plate 10 is polyvinyl chloride, which is an amorphous, odorless, and non-toxic thermoplastic engineering plastic with excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, flexural strength, and compressive strength, low creep, dimensional stability, and good heat resistance and low temperature resistance.

[0023] The installation mechanism includes a mounting frame 9 fixedly installed on the inner wall of the protective frame 3, a moisture-absorbing plate 10 slidably installed inside the mounting frame 9, two fixing plates 11 fixedly installed on both outer walls of the protective frame 3, and a connecting block 13 fixedly installed between the two fixing plates 11 via a rotating mechanism. The rotating mechanism includes a rotating rod 12 rotatably installed between the two fixing plates 11, and the connecting block 13 fixedly installed on the outer wall of the rotating rod 12. A protective cover 15 is fixedly installed on the upper end face of the connecting block 13 via a connecting mechanism. The connecting mechanism includes a connecting rod 14 fixedly installed on the outer wall of the connecting block 13, the end of the connecting rod 14 being fixedly connected to the outer wall of the protective cover 15, and a sealing device fixedly installed on the bottom wall of the protective cover 15. Gasket 16 is made of vulcanized rubber. Vulcanized rubber is rubber that has been vulcanized and has the properties of not being sticky and not being easy to break. Most rubber products are made of this type of rubber, which has high elasticity, heat resistance, tensile strength and insolubility in organic solvents. The upper end face of the protective frame 3 has a sealing groove that matches the gasket 16. The gasket 16 can increase the sealing between the protective cover 15 and the protective frame 3, preventing external moisture from seeping in and affecting the use of the microphone body 1. A handle 17 is fixedly installed on the upper end face of the protective cover 15. An installation opening is opened on the upper end face of the protective cover 15, and an observation glass 18 is fixedly installed inside the installation opening.

[0024] When in use, the microphone body 1 can slide on the upper surface of the mounting plate 2, facilitating flexible installation and position adjustment. The protective frame 3 cooperates with the microphone body 1 to provide initial protection for the microphone body 1. When it is necessary to disassemble or install the microphone body 1, the lever 7 can be moved to cause the fixing pin 6 to disengage from the insertion hole on the connecting plate 5. At this time, the microphone body 1 can be taken out from the protective frame 3. During installation, the fixing pin 6 is inserted into the insertion hole. Under the action of the fixing spring 8, the fixing pin 6 automatically engages with the insertion hole to achieve a stable connection, ensuring that the protective frame 3 tightly wraps the microphone body 1 and prevents external moisture from directly contacting the microphone body 1. When a small amount of moisture enters the internal space of the protective frame 3, the moisture-absorbing plate 10 can absorb the moisture in the air, reduce the humidity inside the protective frame 3, further protect the microphone body 1, and prevent its performance from being affected by moisture. Furthermore, since the moisture-absorbing plate 10 is slidably installed in the mounting frame 9, it is convenient to replace the moisture-absorbing plate 10 after it becomes saturated with moisture.

[0025] When it is necessary to protect the microphone body 1, the protective cover 15 can be rotated by the handle 17 to rotate around the rotating rod 12. The sealing gasket 16 on the bottom wall of the protective cover 15 fits tightly with the sealing groove opened on the upper end face of the protective frame 3 to form a good sealing effect, effectively preventing external moisture from entering the interior of the protective frame 3 and providing further protection for the microphone body 1. In addition, the observation glass 18 installed on the upper end face of the protective cover 15 allows the general condition of the microphone body 1 inside the protective frame 3 to be observed even when the protective cover 15 is closed, which is convenient for maintenance and inspection.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
