Description

Technical Field

[0001] This utility model relates to the field of conference microphone technology, specifically to a multi-channel conference microphone. Background Technology

[0002] Meetings are organized and thematic collective activities conducted by people to achieve information transmission, decision-making discussion, and collaborative communication. They are an important form of organization, management, information exchange, and cooperation in modern society. Due to the large space in medium and large conference rooms, the speaker's voice will attenuate with distance, and participants in the back row or far away from the speaker may have difficulty hearing clearly. Therefore, multi-channel conference microphones are needed. However, multi-channel conference microphones are divided into two types: wireless multi-channel conference microphones and wired multi-channel conference microphones.

[0003] Most wired multi-channel conference microphones currently in use involve plugging the data cable into the microphone's interface. When a speaker uses the microphone, they typically pull it close to their side to ensure communication. However, traditional conference microphones simply plug the data cable into the interface. When the microphone is pulled, the data cable may encounter resistance and be pulled out of the microphone's interface, requiring re-plugging and disrupting the meeting's progress. Furthermore, excessive force during pulling may slightly deform the interface, leading to poor contact between the data cable and the interface, making it inconvenient to use. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-channel conference microphone, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick battery removal and installation device for outdoor instruments, comprising: a microphone body, wherein multiple interfaces are installed on one side of the microphone body, and a data cable is inserted into the inner wall of each interface; multiple dustproof frames are provided on the other side of the microphone body, and the multiple interfaces are all inside the multiple dustproof frames; a clamping plate is provided inside the dustproof frame; a spring is fixedly connected between the upper end of the clamping plate and the inner top of the dustproof frame; a groove is provided through one side of the clamping plate; and the plug of the data cable is disposed inside the dustproof frame.

[0006] As a further preferred embodiment of this technical solution, an extension plate is fixedly connected to the upper end of the clamping plate, the extension plate extends out of the dustproof frame, and multiple anti-slip grooves are provided on both sides of the extension plate.

[0007] As a further preferred embodiment of this technical solution, a mounting groove is provided on one side of the clamping plate, and an abutment plate is slidably connected inside the mounting groove. One side of the abutment plate extends into the groove, and a spring is fixedly connected between the abutment plate and the mounting groove. A dustproof plate is fixedly connected to one side of the dustproof frame.

[0008] As a further preferred embodiment of this technical solution, guide grooves are provided on both sides of the inner wall of the dustproof frame, and the two sides of the clamping plate are slidably connected inside the two guide grooves respectively.

[0009] As a further preferred embodiment of this technical solution, a rubber gasket is fixedly connected to the lower end of the abutment plate.

[0010] As a further preferred embodiment of this technical solution, four mounting bolts are threadedly connected to one side of the dustproof frame. The four mounting bolts are distributed in a rectangular array, and one side of each of the four mounting bolts is threadedly connected to the microphone body.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0012] 1. This utility model, through the structural design of a dustproof frame, a clamping plate, and a spring, allows the dustproof frame to be opened by pulling the extension plate. After inserting the plug of the data cable into the interface, the extension plate is loosened, and the reaction force of the spring pushes the clamping plate downward, locking the data cable in the groove and fixing the plug of the data cable to the interface. This prevents the speaker from pulling the plug of the data cable out of the interface when pulling the microphone body. This structural design ensures the progress of the meeting and avoids the phenomenon of the interface being stretched and deformed.

[0013] 2. This utility model, through the structural design of a dustproof frame, abutment plate, spring 2, and dustproof plate, allows spring 1 and spring 2 to push the clamping plate and abutment plate respectively when the interface is no longer in use. The clamping plate closes the dustproof frame, and the abutment plate closes the groove, thus forming a closed environment inside the dustproof frame. This prevents dust in the air from entering the interface, avoids poor contact of the data cable plug inside the interface, and ensures stable data output. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] This utility model provides a technical solution: such as Figure 1 - Figure 5 As shown, in this embodiment, the multi-channel conference microphone includes: a microphone body 1, a plurality of interfaces 7 are installed on one side of the microphone body 1, a data cable 2 is inserted into the inner wall of the interface 7, a plurality of dustproof frames 3 are provided on the other side of the microphone body 1, the plurality of interfaces 7 are all inside the plurality of dustproof frames 3, a clamping plate 6 is provided inside the dustproof frame 3, a spring 11 is fixedly connected between the upper end of the clamping plate 6 and the inner top of the dustproof frame 3, a groove 8 is provided through one side of the clamping plate 6, and the plug of the data cable 2 is located inside the dustproof frame 3.

[0024] Through the structural design of the dustproof frame 3, the clamping plate 6, and the spring 11, pulling the extension plate 4 opens the dustproof frame 3. After inserting the plug of the data cable 2 into the interface 7, loosening the extension plate 4 causes the reaction force of the spring 11 to push the clamping plate 6 downward, locking the data cable 2 into the groove 8 and fixing the plug of the data cable 2 onto the interface 7. This prevents the speaker from pulling the plug of the data cable 2 out of the interface 7 when pulling the microphone body 1. This structural design ensures the progress of the meeting and avoids the phenomenon of the interface 7 being pulled and deformed.

[0025] It is important to note that the size of the groove 8 is smaller than the plug size of the data cable 2. When the microphone body 1 is in use, the plug of the data cable 2 is inside the dustproof frame 3, and one side of the outer surface of the data cable 2 is inside the groove 8. The interfaces 7 installed on the microphone body 1 include a power interface, a USB interface, an RF antenna interface, and an audio output interface. The microphone body 1 independently transmits and processes audio signals and supports individual control of the signal of each channel, avoiding crosstalk between the microphone body 1 and other microphone bodies 1, thus realizing multi-channel conference microphones. The multiple dustproof frames 3 have the same structure and are used in the same way.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, an extension plate 4 is fixedly connected to the upper end of the clamping plate 6. The extension plate 4 extends out of the dustproof frame 3. Multiple anti-slip grooves 13 are provided on both sides of the extension plate 4. The structural design of the anti-slip grooves 13 makes it convenient for workers to pull the extension plate 4.

[0027] like Figure 3 - Figure 5 As shown, a mounting groove is provided on one side of the clamping plate 6, and an abutment plate 9 is slidably connected inside the mounting groove. One side of the abutment plate 9 extends into the groove 8, and a spring 15 is fixedly connected between the abutment plate 9 and the mounting groove. A dustproof plate 10 is fixedly connected to one side of the dustproof frame 3. When the other interfaces 7 are no longer in use, the dustproof frame 3 is in a closed environment to prevent dust in the air from entering the interface 7, avoid poor contact of the plug of the data cable 2 in the interface 7, and ensure stable data output.

[0028] like Figure 4 As shown, guide grooves 12 are provided on both sides of the inner wall of the dustproof frame 3, and the two sides of the clamping plate 6 are slidably connected inside the two guide grooves 12 respectively; the guide grooves 12 are used to limit the sliding direction of the clamping plate 6 and prevent the clamping plate 6 from deviating when sliding.

[0029] like Figure 5 As shown, a rubber gasket 14 is fixedly connected to the lower end of the abutment plate 9; the rubber gasket 14 is used to protect the rubber on the surface of the data cable 2 and prevent damage to the surface of the data cable 2.

[0030] like Figure 2 - Figure 4 As shown, four mounting bolts 5 are threadedly connected to one side of the dustproof frame 3. The four mounting bolts 5 are distributed in a rectangular array, and one side of each of the four mounting bolts 5 is threadedly connected to the microphone body 1. The mounting bolts 5 are used to install and remove the dustproof frame 3, which facilitates the maintenance and replacement of the structure inside the dustproof frame 3.

[0031] This utility model provides a multi-channel conference microphone, the specific working principle of which is as follows:

[0032] When installing the microphone in the conference room, first pull the extension plate 4 to open the dustproof frame 3. After inserting the plug of the data cable 2 into the interface 7, loosen the extension plate 4. The reaction force of the spring 11 will push the clamping plate 6 downward, locking the data cable 2 into the groove 8 and fixing the plug of the data cable 2 onto the interface 7. After installation, when the conference room needs to be used, the speaker uses the microphone body 1 to speak. During the speaking process, pulling the microphone body 1 will move the microphone body 1 along with the plug of the data cable 2, preventing the plug from falling out of the interface 7 and affecting the progress of the meeting.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
