Problems solved by technology

However, the application scenarios of this method are relatively limited. It must be applied to the on-board microphone or when there is grounded metal around the microphone, so as to ensure that the aluminum foil is grounded, thereby playing the role of electrostatic isolation.

Abstract

The present invention discloses a pickup device and a cavity wall member for the pickup device, comprising: a housing having a pickup hole on a surface thereof; a microphone, wherein the microphone isarranged in the shell; a tunnel sound cavity which is formed in the shell, the microphone is formed in the shell, the tunnel sound cavity is formed in the shell and isolated between the pickup hole and the microphone, the pickup hole and the microphone are both communicated with the tunnel sound cavity, and sound waves entering the shell through the pickup hole are collected by the microphone through the tunnel sound cavity. According to the pickup device and the cavity wall component for the pickup device, the tunnel sound cavity is formed between the pickup hole and the microphone to increase the distance between the pickup hole and the microphone so as to achieve the effect of electrostatic isolation; and the loss of the sound intensity caused by the distance is compensated through theoscillation effect of the sound wave in the tunnel sound cavity.

Description

technical field [0001] The invention relates to the technical field of sound pickup equipment, in particular to a sound pickup equipment and a cavity wall member used for the sound pickup equipment. Background technique [0002] In the recording device, because the distance between the recording hole of the microphone and the microphone is too close, static interference is likely to be generated, which will cause damage to the microphone or internal circuits and affect the use effect. At present, the main ways to solve the problem of electrostatic interference in the recording hole are hardware circuit protection and structural shrinkage design. [0003] For some chips with weak antistatic ability, when the product thickness is thin and the structure shrinkage cannot meet the electrostatic insulation requirements, the hardware circuit protection alone cannot solve the electrostatic interference problem; although the structure shrinkage can better solve the electrostatic inte...
