Abstract

The present invention provides a speaker vibration detecting device. Through a permanent magnet fixed by a spring and disposed in the middle of a coil, and through the spring's vibration that drives relative displacement of the permanent magnet relative to the coil, the device makes a magnetic field change, further generates electromotive force in the coil; and displays a specific value of a testthrough a display module by a test circuit module, the device makes vibration setting more accurate and intuitively readable, miniaturizes the speaker vibration detecting device, increases sound compliance and improves sound quality when the speaker vibration detecting device is used in a sound sensor.

Description

technical field [0001] The invention relates to the field of vibration testing, in particular to a horn vibration detection device. Background technique [0002] Currently, a horn vibration detection device is being developed using semiconductor integrated circuit manufacturing technology. The horn vibration detection device has monocrystalline silicon or polycrystalline silicon laminated on a silicon substrate to form a thin film, and the thin film is used as a diaphragm. A diaphragm made of silicon has less internal stress and a lower density than metals such as aluminum or titanium, so a horn vibration detection device with high sensitivity can be obtained, and it has a good compatibility with the manufacturing process of semiconductor integrated circuits. In the prior art condenser microphone, after a diaphragm (movable electrode) and a fixed electrode are formed on the surface of a semiconductor substrate made of a single crystal silicon surface, an etching mask is form...
