Abstract

An active anti-vibration microphone comprises a handle unit, a cover cap connected to the handle unit, and a circuit unit and a sound head module arranged in the handle unit. The handle unit comprises a casing around the axis and a contact base fixed in the casing and around the axis. The cover cap and the casing define an accommodating cavity for accommodating the sound head module. The sound head module comprises a bearing seat, a main conversion unit and an auxiliary conversion unit. The bearing seat includes a hollow segment and first and second bearing segments, the hollow segment is fixed to the contact base, the first and second bearing segments accommodate the main conversion unit and the auxiliary conversion unit respectively, and the first bearing segment is closer to the cover cap than the second bearing segment. The main conversion unit includes a diaphragm which can generate first vibration with seismic and sound waves, and the first vibration can be converted into a first electrical signal including primary and secondary electrical signals. The auxiliary conversion unit includes a diagram which can generate second vibration and can convert the second vibration into a second electrical signal including the secondary electrical signal. The conversion units are connected to the circuit unit via opposite polarities, the secondary electrical signal converted by the seismic waves can be offset, and noises are reduced greatly.

Description

technical field [0001] The invention relates to a microphone, in particular to an active anti-vibration microphone (Active vibration canceling microphone). Background technique [0002] refer to figure 1 and figure 2 , a conventional passive anti-vibration microphone 9, including a handle 91 with a housing space 910, a head module 92 arranged in the housing space 910, a top edge connected to the handle 91 and The cover 93 covering the capsule module 92 , a double shock-absorbing unit 94 located in the housing space 910 , and an external terminal 95 disposed at a bottom edge of the handle 91 . [0003] The head module 92 has an audio conversion group 921 , a bearing seat 922 for carrying the audio conversion group 921 , and a wiring board 923 . The audio switching unit 921 is a dynamic microphone capsule known in this technical field. The wiring board 923 of the audio head module 92 is disposed on a bottom edge of the supporting seat 922 and is electrically connected to ...
