The classification of headphones sockets is introduced to you today. Of course, the sockets used in different appliances are different. In addition, there are different sizes of inner tibia. So we need to understand these contents in detail, please have a look.

Headphones socket power chips can be divided into four types: pulse width modulator (PWM), what is a DC/DC converter: DC/DC converter is a device that converts one DC voltage into another (or several) DC voltage through switching devices.

Switch regulator for headphones socket:

Switching Voltage Regulator (hereinafter referred to as Switching Regulator) generally refers to low-voltage DC/DC converters. When constructing switching power supply, it is necessary to equip headphones socket with power frequency transformer and input rectifier filter. The materials used in headphones sockets are excellent in flame retardancy, insulation, impact resistance and moisture proof. The material is stable and does not change color easily. Nowadays, besides the use of high-grade plastics, the switch panel also has gold-plated, stainless steel, copper and other metal materials, which provides people with more and more choices. Pure silver contacts and conductive bridges made of silver-copper composite materials can prevent oxidation caused by arc when the switch is on or off. Silver-nickel-copper composite material is used for conductive bridge of high-quality panel. Silver material has excellent conductivity. Silver-nickel alloy has strong ability to restrain arc, which ensures that the switch can be opened and closed more than 80,000 times, far exceeding the international standard of 40,000 times. The switch with brass screw wire pressing has large contact surface, strong wire pressing ability and stable and reliable wiring. If it is a single hole connection copper pillar, the connection capacity is large, not limited by the wire thickness, it is very convenient.

This is the classification of headphones sockets when they are used. Please pay attention to it when you choose and use them.
