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.

Description

technical field [0001] The invention relates to an audio power amplifier circuit capable of amplifying and outputting audio signals and outputting low-frequency signals. Background technique [0002] The main function of the existing audio power amplifier is to amplify the audio signal and output it with a loudspeaker, which is mainly used by people to enjoy music, to achieve the purpose of entertainment and enjoyment, and to relax people's body and mind. However, the audio function of the existing audio power amplifier is simple, and the product lacks novelty. A circuit structure of an existing audio amplifier mainly includes a two-way audio signal input circuit part, a signal strength adjustment part, an audio output power amplifier part, a remote control part and a power supply part, and the two-way audio signal input circuit part provides a two-way audio signal for the circuit. The input signal is adjusted by the signal strength adjustment part, amplified by the audio o...
