Knowledge of headphone socket

 

We don't know much about headphone socket, because we tend to focus on other switches in many times. But today, Dongguan Pindi Electronic Technology Co., Ltd. will explain these knowledge to you, hoping you can correctly judge the use function of headphone socket through these situations.

Once the input voltage of headphone socket is chopped into AC square wave, its amplitude can be increased or decreased through transformer. The number of output voltage groups can be increased by increasing the number of secondary windings of the transformer. "Home appliance accidents, home fires and so on have made us gradually understand the importance of safe use of electricity." "On the one hand, the safety performance of the breakout socket is excellent. It has five core safety protection technologies, such as fire prevention and leakage prevention, professional intelligent lightning protection, deterioration protection, bodyguard overload switch, love double action protection door, which can effectively protect the safety of consumers' home appliances and their families' electricity and meet the needs of consumers. The duty cycle of the other pulse is regulated by the controller of the switching power supply.

The main purpose of the controller is to keep the output voltage stable. Its working process is similar to that of the linear controller. In other words, the function block, voltage reference and error amplifier of the controller can be designed to be the same as the linear regulator. The difference between them 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 electron is positron, whose mass, spin and charge are the same as that of electron, but the positive and negative of charge are opposite to that of electron. Electrons and positrons annihilate each other by colliding. In this process, more than one pair of photons are created. The electron is negatively charged and rotates around the nucleus. The interaction force of electrons moving at the same speed of light in the same direction is zero.

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