Embodiment Construction

[0011] As shown in the figure, the present invention includes a power amplifier, a bias circuit, a triode, a relay, a drive module, a processor, a tuning module and a voltage regulator, and is characterized in that: the processor passes through the drive module, the power amplifier, the bias The setting circuit, the triode are connected with the relay; the processor is also connected with the voltage stabilizer and the tuning module.

[0012] The processor is a single-chip microcomputer.

[0013] The tone controller is used to process and polish the audio signal and realize various adjustment and control functions, so that the replayed sound can achieve a better sound effect. A general tone controller boosts or cuts the gain of the bass and treble, and keeps the gain of the midrange signal constant. In this way, it can be used to achieve effects such as heavy bass. The key to the audio controller is the frequency selection function of the resistance-capacity filter net...

The invention provides an audio amplification system which is low in noise, small in distortion and stable in performance. The system comprises a power amplifier, a biasing circuit, a triode, a relay, a driving module, a processor, a toning module and a voltage stabilizer and is characterized in that the processor is connected with the relay via the driving module, the power amplifier, the biasing circuit and the triode; and the processor is further connected with the voltage stabilizer and the toning module.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to an improvement of an audio frequency amplification system. Background technique [0002] Audio amplifiers have a history of nearly a century, and the first application of the earliest tube amplifiers was audio amplifiers. However, until now, it is constantly updating, developing and advancing. The main reason is that human hearing is a very important and the most basic of all senses. In order to meet its needs, related audio amplifiers will be continuously improved. After entering the 21st century, various portable electronic devices have become an important development trend of electronic devices. From the mobile phone as a communication tool to the MP3 player as an entertainment device, it has become a portable electronic device that almost everyone has. Portable TV sets, portable DVDs, etc. will be popularized one after another. What all these portable ele...
