What Is Motional Feedback Loudspeaker?

- Jun 21, 2018-

Motional feedback is the feedback of the counter-phase electromotive force (voltage) of a voice coil, which is proportional to the vibration of the speaker's vibration system, to the input of the power amplifier as a drive system to control the vibration mode of the vibration system. It cannot effectively reduce the distortion of the speaker vibration system and improve the sound pressure frequency response characteristics. Its working principle is basically the same as a negative feedback amplifier.
