What Is Motional Feedback Loudspeaker?

- Aug 27, 2018-

Motional feedback refers to feeding back the voice coil reverse electromotive force (voltage) proportional to the vibration of the speaker vibration system to the input of the power amplifier as the drive system to control the vibration mode of the vibration system. It can inefficiently reduce the distortion of the speaker vibration system and improve the sound pressure response characteristics. Its working principle is basically the same as that of the negative feedback amplifier.
