Abstract

The invention discloses a power amplifying circuit with high tone quality. The power amplifying circuit comprises a power supply, a transformer, a first diode, a second diode, a third diode, a fourth diode, a fifth diode, a sixth diode, a seventh diode, an eighth diode, a ninth diode, first to eighteenth capacitors, a first inductor, a second inductor, a triode, a relay, first to twelfth resistors, a time base chip, a potentiometer, a first amplifier, a second amplifier and a speaker. The power amplifying circuit has the advantages of relatively simple structure and low cost, some super-audio frequency signals mixed in audio signals are removed, and the degree of distortion of a power amplifier at large volume is reduced, so that the sound is more pleasant to hear, combined filtering of the inductors and the capacitors is adopted on a filter circuit, the filter is generally used in a professional instrument and has better performance than a simple capacitor filter.

Description

technical field [0001] The invention relates to a power amplifier circuit, in particular to a power amplifier circuit with high sound quality. Background technique [0002] The development of audio technology has gone through the historical period of electron tubes, transistors, and field effect tubes, and each has its own characteristics in different historical periods. The audio amplifier is a device that restores electrical signals to sound signals, and the authenticity of the restoration will be used as an important criterion for evaluating the performance of speakers. Some current power amplifiers use servo DC technology, which improves the performance to a certain extent, but the effect is not great, and the complexity of the circuit is greatly increased. Many low-end power amplifiers have poor sound quality and are prone to distortion, while high-end power amplifiers have good sound quality But too expensive. Contents of the invention [0003] The object of the pr...
