Problems solved by technology

[0002] At present, the microphones used in communication equipment such as mobile phones are mostly electret condenser microphones. This type of microphone has a simple structure, small size and good performance, which has played a great role in the popularization of communication products. The current electret capacitor The microphone design is mature, but when users use communication equipment, in some special cases, such as strong winds, driving a motorcycle, the other party will hear the sharp wind sound, which affects the call effect, and sometimes people can't even hear the other party clearly. What to say, based on this kind of user experience, the design of the electret condenser microphone needs to be improved

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like figure 1 , figure 2 , image 3 As shown, the windproof microphone includes a shell 1, and one end of the shell 1 is provided with a sealing plate 10, and the sealing plate 10 is provided with an external sound transmission hole 11, and a circuit board 9 is arranged inside the shell 1, A pole capacitor composed of a vibrating diaphragm 2 and a back plate 3 is provided between the circuit board 9 and the sealing plate 10, and a capacitor is arranged between the sealing plate 10 and the vibrating diaphragm 2. The windproof sheet 4, due to the design of the built-in windproof sheet, the windproof sheet 4 is arranged inside the cylindrical shell 1 to prevent the air flow from directly acting on the vibrating diaphragm 2, and has a good windproof ability. The windproof sheet 4 and A gap 12 is provided between the sealing plates 10, and the windproof...

Abstract

The invention relates to a wind-proof microphone. The wind-proof microphone comprises a shell (1), wherein a sealing plate (10) is arranged at one end of the shell (1) and provided with an external soniferous hole (11); a circuit board (9) is arranged in the shell (1); a pole head capacitor consists of a vibrating diaphragm (2) as well as a backplate (3), and is arranged between the circuit board (9) and the sealing plate (10); a wind-proof sheet (4) is arranged between the sealing plate (10) and the vibrating diaphragm (2); a gap (12) is reserved between the wind-proof sheet (4) and the sealing plate (10); a wind-proof sheet soniferous hole (41) is formed on the wind-proof sheet (4) and interleaved with the external soniferous hole (11); and the external soniferous hole (11) is communicated with the wind-proof sheet soniferous hole (41) through the gap (12). Compared with a conventional electret condenser microphone, the microphone provided by the invention has an excellent wind-proof capacity, and the wind noise ratio is more than 10 dB lower than that of the conventional microphone.
