Debugging method for power amplifier and mobile terminal

Abstract

The invention discloses a debugging method for a power amplifier and a mobile terminal. The power amplifier comprises a machine body and a rack body positioned on the bottom of the right end of the machine body; an accommodating groove is formed in the right end surface of the machine body; a left chute is formed in the bottom end wall of the accommodating groove; a right chute which is opposite to the left chute and communicates with the left chute is formed in the top end surface of the rack body; and a right slider capable of sliding in the left-right direction is arranged in the right chute. The device is simple in integral structure and convenient and speedy to operate, automatic energizing of the mobile terminal and the power amplifier can be realized, the mobile terminal and the power amplifier cannot be switched on or switched off simultaneously, the circumstance that the mobile terminal and the power amplifier are damaged simultaneously under the condition that the mobile terminal and the power amplifier are simultaneously switched on or switched off is avoided, the service life of equipment is prolonged, the using cost is reduced, electric shock accidents caused by manualenergizing are completely eradicated, and meanwhile, the mobile terminal is protected through a rotatable protecting assembly.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a debugging method of a power amplifier and a mobile terminal. Background technique [0002] With the development and progress of science and technology, communication technology has developed rapidly and made great progress. With the improvement of communication technology, the popularity of smart electronic products has reached an unprecedented height. More and more smart terminals or mobile terminals have become people's An integral part of life, such as smartphones, smart TVs, and computers; and power amplifiers are referred to as "power amplifiers" for short, which means that under a given distortion rate condition, the maximum power output can be generated to drive a load (such as a speaker) The power amplifier plays a pivotal role in the "organization and coordination" of the entire audio system, and to some extent determines whether the entire system can provide goo...

AI Technical Summary

Problems solved by technology

[0003] The power amplifier is an indispensable part of a smart terminal or a mobile terminal. However, both the mobile terminal and the power amplifier need to be powered on before they can be used. The current power supply for the mobile terminal and the power amplifier is directly powered, that is, the power of the mobile terminal When the amplifier is powered on, when there is a fault or a short circuit, it is easy to cause the mobile terminal and the power amplifier to be burned at the same time, which will increase the cost of equipment use. In addition, the current power on of the mobile terminal is manually operated. Electric shock accidents are likely to occur when the power is turned on
