The knowledge about headphone sockets is not much, because in many cases it will focus on other switches, but today Dongguan Dongkun Electronic Technology Co., Ltd. will explain these aspects of knowledge to you, I hope you can correctly judge the use of headphone sockets through these circumstances.

Once the input voltage of headphone socket is chopped into AC square wave, its amplitude can be increased or decreased by transformer. By increasing the number of secondary windings of the transformer, the number of output voltage groups can be increased. "The emergence of household appliances accidents, family fires and so on, finally let us gradually understand the importance of safe electricity use." The person laughed: "On the one hand, the breakthrough socket has excellent safety performance. It has five core safety protection technologies: fire prevention and leakage protection, professional intelligent lightning protection, deterioration protection, bodyguard anti-overload switch, loving double-action protection door, which can effectively protect consumers'household appliances and household electrical safety and meet consumers' needs. Use demand. In addition, the duty cycle of the pulse is regulated by the controller of the switching power supply.

The final AC waveforms of the headphone socket are filtered by rectifier to get the DC output voltage. The main purpose of the controller is to keep the output voltage stable. The working process of the controller is very similar to that of the linear controller. That is to say, the function block, voltage reference and error amplifier of the controller can be designed to be the same as the linear regulator. Their difference is that the output of the error amplifier (error voltage) passes through a voltage/pulse width conversion unit before driving the power transistor. The antiparticle of an electron is a positron. Its mass, spin and charged quantity are the same as that of an electron, but the positive and negative electric quantity are opposite to that of an electron. Electrons and positrons annihilate each other by collision, in which more than one pair of photons are created. Electrons are negatively charged and rotate around the nucleus. The interaction force of electrons moving in the same direction at the speed of light is zero.

This is the related problem of headphone socket. I hope you can better examine these problems.
