Abstract

An active anti-seismic microphone includes a handle unit, a cover connected to the handle unit, a circuit unit and a sound head module arranged on the handle unit. The handle unit includes a housing surrounding the axis and a contact seat fixed in the housing and surrounding the axis. The cover and the casing define a chamber for accommodating the head module. The sound head module includes a bearing seat and a main and a secondary conversion unit. The carrying seat is fixed to the hollow section of the contact seat and the first and second carrying sections for accommodating the primary and secondary conversion units. The first carrying section is adjacent to the cover relative to the second carrying section. The main conversion unit has a vibrating membrane capable of generating first vibrations along with shock waves and sound waves, and can convert the first vibrations into first electrical signals including primary and secondary electrical signals. The secondary conversion unit has a diaphragm that can generate a second vibration with the shock wave and can convert the second vibration into a second electrical signal containing a secondary electrical signal. The conversion unit is electrically connected to the circuit unit with the opposite polarity, which can cancel out the shock wave The converted electrical signal greatly reduces noise.

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 ...
