Silicon microphone with sound tunnel and sound beam

Abstract

The invention relates to the technical field of microphone equipment, in particular to a silicon microphone with a sound tunnel and a sound beam. The microphone comprises a base, a support rod is arranged on the base, and a cleaning mechanism is connected to one end, away from the base, of the support rod; the base is detachably connected with a liquid storage mechanism; a placement mechanism is arranged on the base; a reciprocating mechanism is mounted on the base; a pumping mechanism is assembled on the base, and the reciprocating mechanism drives the pumping mechanism; through the arrangement of the placement mechanism, the base can be conveniently fixed on a desktop, so the microphone is prevented from being touched by mistake when being used; through the arrangement of the reciprocating mechanism, the pumping mechanism is conveniently driven to operate, the pumping mechanism conveys liquid in the liquid storage mechanism into the cleaning mechanism, meanwhile, waste liquid in the cleaning mechanism is recycled into the liquid storage mechanism to be stored, and then the clean and sanitary effect of the silicon microphone with the sound tunnel and the sound beam is conveniently improved; and the microphone is prevented from generating peculiar smell after being used for a long time.

AI Technical Summary

Problems solved by technology

[0002] Microphones are energy conversion devices that convert sound signals into electrical signals. They are classified into dynamic, capacitive, electret and recently emerging silicon micro-microphones. In addition, there are liquid microphones and laser microphones. The polymer material diaphragm with permanent charge isolation is now generally used as an acoustic transducer with a sound tunnel and a sound beam in order to reduce the volume of the microphone. When the diaphragm of a silicon microphone receives sound waves from an external sound source, due to its existence An inherent resonant frequency, if it exceeds a certain range of the resonant frequency area, there is a problem that the high-pitched and low-pitched areas cannot effectively resonate, resulting in the received sound being converted by "sound-electricity" and then restored by "electricity-sound". The high-pitched sound quality has the problem that the high-pitched area is not bright, and the low-pitched area is not thick and round enough, which leads to poor sound fidelity. In the utility model patent with application number 202021741046.6, it is mentioned that "a full-band silicon Mai" solves the above problems

[0003] However, traditional microphones generally only have the function of adjusting the placement angle, and the base is generally simply placed on the table. When using it, it is necessary to consider the angle of the base to support the microphone to prevent the microphone from tipping over and reduce the use of the microphone. Flexibility. After the microphone is used for a period of time, the internal sanitation of the microphone without cleaning components is extremely bad due to the saliva and other debris on it, and it is accompanied by peculiar smell, which greatly reduces the use effect of the microphone.
