[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a microphone, including a shell, a main bracket 1, a microphone head 4, a main control circuit board 5 and a battery 6. The main bracket 1 includes a top cover connecting ring 11, a middle connecting plate 13, a bottom connecting frame 14 and at least one connecting column 12. The top cover connecting ring 11 is arranged at intervals on the top side of the middle connecting plate 13. The connecting column 12 connects the top cover connecting ring 11 and the middle connecting plate 13 to form a pickup cavity 15 between the top cover connecting ring 11 and the middle connecting plate 13. The microphone head 4 is located in the pickup cavity 15 and is fixed on the middle connecting plate 13.

[0025] The top side of the bottom connecting frame 14 is connected to the middle connecting plate 13 , the main control circuit board 5 and the battery 6 are fixed to the bottom connecting frame 14 , and the battery 6 is electrically connected to the main control circuit board 5 and the microphone 4 .

[0026] The shell includes a top cover 2 and a bottom shell 3 . The bottom shell 3 is covered on the outside of the main bracket 1 and connected to the bottom connecting frame 14 . The top cover 2 is connected to the top cover connecting ring 11 .

[0027] The main control circuit board 5 controls most of the microphone's functions, including microphone gain, microphone output volume, power on / off, and status indicators. Microphone head 4 is used solely for sound pickup and is essentially responsible for sampling the analog signal and transmitting it to the main control circuit board 5. The MCU on the main control circuit board 5 analyzes and processes the signal (ADC - amplification - output), and then adjusts the preset output mode based on user keystrokes.

[0028] When assembling the microphone, first fix the battery 6 and the main control circuit board 5 to the bottom connecting frame 14 of the main bracket 1, install the microphone head 4 into the pickup cavity 15 and fix it to the middle connecting plate 13 to form a module, then put the bottom shell 3 on the outside of the module, connect the top cover 2 to the top cover connecting ring 11, and connect the bottom shell 3 to the bottom connecting frame 14.

[0029] Compared with the prior art of placing each part one by one into the corresponding position in the shell, in the microphone of the present invention, the assembler can first assemble each component on the main bracket 1 outside the shell, and then assemble the whole with the shell, which can effectively improve the assembly efficiency of the microphone.

[0030] At the same time, since the connecting column 12 connects the top cover connecting ring 11 and the middle connecting plate 13 that are spaced apart, a sound pickup cavity 15 is formed between the top cover connecting ring 11 and the middle connecting plate 13. Therefore, the sound pickup cavity 15 is an open structure, and the side space of the sound pickup cavity 15 is open, which facilitates the placement of the microphone 4 from the side of the sound pickup cavity 15.

[0031] Moreover, the top cover connecting ring 11, the middle connecting plate 13 and the bottom connecting frame 14 of the main bracket 1 can provide a sufficiently stable installation and connection position for the top cover 2, the microphone 4, the main control circuit board 5, the battery 6 and the bottom shell 3, thereby improving the stability of the connection between the main bracket 1 and the shell, and thereby improving the stability of each component fixed on the main bracket 1 in the shell.

[0032] In the microphone of the present invention, when assembling the microphone, the battery 6 and main control circuit board 5 are first secured to the bottom connecting bracket 14 of the main bracket 1, the microphone head 4 is inserted into the pickup cavity 15 and secured to the central connecting plate 13, forming a module. The bottom shell 3 is then placed over the module, the top cover 2 is connected to the top cover connecting ring 11, and the bottom shell 3 is connected to the bottom connecting bracket 14. Compared to the prior art method of placing each component into the corresponding position within the shell, the assembler of the microphone of the present invention can first assemble each component on the main bracket 1 outside the shell, and then assemble the entire assembly with the shell, which effectively improves the assembly efficiency of the microphone.

[0033] In one embodiment, if Figure 3 As shown, the bottom connecting frame 14 includes a bottom plate 141 and a support column 142. The bottom plate 141 is spaced apart on the bottom side of the middle connecting plate 13. The support column 142 connects the middle connecting plate 13 and the bottom plate 141 to form a main control cavity between the bottom plate 141 and the middle connecting plate 13. The main control circuit board 5 is vertically arranged in the main control cavity.

[0034] Since the support column 142 connects the spaced middle connecting plate 13 and the bottom plate 141, a main control cavity is formed between the middle connecting plate 13 and the bottom plate 141. Therefore, the main control cavity is an open structure, and the side space of the main control cavity is wide, which facilitates the vertical installation of the circuit board from the side of the main control cavity to further improve the assembly efficiency.

[0035] In one embodiment, the support column 142 extends linearly along the length of the microphone.

[0036] In one embodiment, if Figure 2 and Figure 3 As shown, there are two support columns 142, which are spaced apart along a first direction, and the main control circuit board 5 is vertically arranged between the two support columns 142; wherein the first direction is perpendicular to the length direction of the microphone to improve the firmness of the connection between the middle connecting plate 13 and the bottom plate 141, thereby improving the structural strength and stability of the main bracket 1.

[0037] In one embodiment, the bottom plate 141 is a circular plate, and the first direction is a radial direction of the bottom plate 141 .

The main control circuit board 5 is fixed to the side of the mounting plate 143. The large contact area between the mounting plate 143 and the main control circuit board 5 ensures high stability of the main control circuit board 5 on the bottom connecting frame 14.

The microphone bracket 41 is elastically deformed, and the middle connecting plate 13 is stuck in the slot of the microphone bracket 41, thereby fixing the microphone 4 on the middle connecting plate 13.

[0044] In one embodiment, if Figure 3 As shown, there are two connecting columns 12, and the two connecting columns 12 are symmetrically arranged on the outside of the microphone mounting hole 16 along the first direction, so as to ensure the connection strength between the middle connecting plate 13 and the top cover connecting ring 11, thereby ensuring the overall structural strength and stability of the bracket.

[0045] Moreover, the two connecting columns 12 and the two supporting columns 142 are spaced apart along the first direction, so that the main control cavity and the pickup cavity 15 are both open structures facing the same side of the bracket. When assembling the microphone, the assembler can install the microphone head 4 into the pickup cavity 15 and the main control circuit board 5 into the main control cavity from the same side of the bracket without adjusting the assembly direction.

[0046] In one embodiment, if Figure 2 As shown, the microphone also includes a touch circuit board 7. The top cover 2 has an inner cavity opening toward one side of the bottom case 3.
