Problems solved by technology

[0002] Ordinary power amplifiers, once set, the magnification factor remains the same, but for different signal sources, the input signal size is different, it will encounter the trouble of constantly adjusting the power when switching, such as TV channel switching, karaoke programs The volume and the relationship between the microphone and music, and the moment the power is turned on, the power amplifier is likely to generate an impact signal and cause damage to the output unit

Embodiment 1

[0015] Example 1 (Smart Power Amplifier)

[0016] The present invention provides an intelligent power amplifier. Using the self-adaptive power amplifier, the output power can be automatically adjusted to keep the output volume constant, and the volume amplification, echo adjustment, vibrato, etc. of the microphone can also be automatically adjusted to realize no matter what connection is connected. The microphone can achieve the same effect. You can also receive broadcast station signals for playback. In addition, it contains an external sampling unit. When the position of the speaker is adjusted, the signal collected by the external sampling unit changes. The smart power amplifier is adjusted through the automatic amplification function provided by the adaptive power amplifier, so that the influence caused by the moving speaker position can be passed through the smart power amplifier. Get some compensation. Therefore, by driving the motor of the speaker base, the smart power ampl...

Abstract

This invention discloses an adaptive power amplifier, the amplification multiple of which is adjusted automatically and is decided according to the difference between the internal sample value of an input signal or the outer sample value of an output signal and the limit value of the output signal set currently, and the limit value of the output signal is controlled by increasing or reducing outside circuits and parameters set by the adaptive power amplifier also includes the smallest and the largest output amplitudes of a signal, retarding space and time interval of the regulation of amplified times. When a signal is input, the amplifier can regulate power according to the input signal sample value and the limit value of an output signal set currently, when it is shielded, it stores the current amplified multiple parameter and maintains the current one till it starts up again.

Description

Technical field [0001] The invention relates to a power amplifier with an automatically adjustable amplification factor. Background technique [0002] Ordinary power amplifier, once set, the magnification will not change, but for different signal sources, the input signal size is different, you will encounter the trouble of constantly adjusting the power when switching, such as TV switching channels, karaoke programs The volume and the coordination relationship between the microphone and the music, and the power amplifier at the moment of turning on the power is likely to produce an impact signal that will damage the output unit. Summary of the invention [0003] The invention solves the shortcomings of traditional power amplifiers that do not have automatic adjustment function and protects the output unit, and provides an adaptive power amplifier, which adopts an integrated chip design and is a power amplifier with an automatically adjustable amplification factor. The amplifica...
