A new type of unidirectional microphone

Abstract

The invention discloses a novel unidirectional microphone, which comprises a dust-proof net, a casing, a circuit board, a vibrating film, a cavity, a back pole, and conductive glue. A sound groove is set between the glue, a micro-shaped exhaust groove is set in the cavity, and an exhaust hole is set in the outer shell. The exhaust hole corresponds to the micro exhaust groove of the cavity to form an acoustic cavity exhaust system, so that the present invention can filter out ambient noise. , to reduce the sound in other directions, so as to collect clear high-fidelity sound in one direction, and the invention is specially designed for the vehicle with a consistent mechanical structure, with better use effect and longer life.

Description

technical field [0001] The invention relates to a microphone, in particular to a novel unidirectional microphone. Background technique [0002] With the development of science and technology and the informatization of communication, microphones are used in many electronic products. The development of modern microphone technology has made the application of unidirectional electret microphones more and more extensive. With the development of communication information It is getting higher and higher, the complexity of its surrounding environment, followed by recording, singing, conference systems and other high-end electronic products have higher and higher requirements for sound pickup, but traditional unidirectional electret microphones are difficult to collect clear and high-fidelity sound, The sound from other directions around it cannot be well reduced, the environmental noise cannot be well filtered, and the effect of using it in a car is even worse.

[0002] With the development of science and technology and the informatization of communication, microphones are used in many electronic products. The development of modern microphone technology has made the application of unidirectional electret microphones more and more extensive. With the development of communication information It is getting higher and higher, the complexity of its surrounding environment, followed by recording, singing, conference systems and other high-end electronic products have higher and higher requirements for sound pickup, but traditional unidirectional electret microphones are difficult to collect clear and high-fidelity sound, It can't reduce the sound from the rest of the surrounding directions well, can't filter the environmental noise well, and the effect of using it in a car is even worse.
