Abstract

The present invention discloses a low -inconsistent power amplifier system based on the opening and turbulence of the noise circuit. It is characterized by a static bias circuit, which is connected to the static bias circuit.Connecting noise inhibitory circuit, connecting negative electrode and noise inhibitory circuit, the positive electrode as the capacitor C1 of the input terminal of the amplifier system, one end connects to the negative electrode of the capacitance C1, and the other end of the ground resistance R1.The present invention can automatically execute the mute when connecting the power supply, eliminating the impact of the speaker when the large current when it is power -over, thereby protecting the speaker.

Description

technical field [0001] The invention relates to a power amplifier system, in particular to a noise-suppressing low-distortion power amplifier system based on a squelch circuit of a switch machine. Background technique [0002] The power amplifier system is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source to drive the speaker to emit sound. However, there is a big problem in the existing power amplifier system, that is, the amplified signal tends to be distorted to varying degrees, which leads to signal distortion and seriously affects the auditory effect. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current power amplifier system easily distorts the signal after amplifying the signal, resulting in signal distortion, and provides a noise-suppressed low-distortion power amplifier system based on the switch squelch circuit. [0004] The purpose ...
