Bone conduction microphone

Abstract

The invention provides a bone conduction microphone. The bone conduction microphone comprises a shell, a seal cap connected with the shell, and a sound pick-up arranged in the shell. A connecting cylinder is arranged in the shell, and the sound pick-up is arranged in the connecting cylinder. With the structure, vibration on the shell can be prevented from entering into the sound pick-up through screening of the shell, noise can be avoided, and therefore sound articulation can be improved.

Description

technical field [0001] The invention relates to a bone conduction microphone. Background technique [0002] General microphones use air conduction and are open. Although they can obtain good sound quality, the biggest disadvantage is that they cannot isolate the external background sound source. When talking in a noisy environment, they cannot filter the ambient noise, causing inconvenience to the user. Compared with the microphone that uses air conduction for detection, the bone conduction microphone has stronger anti-noise ability because it is attached to the user's skull and detects the vibration of the skull when the user speaks through bone conduction. [0003] The Chinese patent with the authorized notification number CN2814852Y discloses a bone conduction microphone, wherein the microphone and the vibrating surface are connected to each other through a shell, and the vibrating surface and the shell are flexibly connected to form a bone conduction microphone between t...
