Abstract

This invention is a kind of somesthetic vibration sounding power amplification circuit. It mainly concludes audio signal input part, audio signal output power amplifier part, remote controller part and power supply part. It also concludes a low-frequency circuit which can output low-frequency signals. This circuit is consisted with two-stage low-pass filter circuit, protection circuit and low-frequency signals amplifier. The high-frequency part of inputted audio signals is filtered by two-stage low-pass filter circuit. The low-frequency signals are amplified by low-frequency signals amplifier and outputted. The outputted signals make the energy transformer generate mechanical vibration effect. The vibration strength is controlled by remote controller.
