When using the headphone socket, we should pay attention to the wiring method, and how to wiring it? What is the specific method? Let's give you a detailed introduction.

Earphone sockets are commonly used in people's daily life, but for unrelated workers, they still know little about them, such as how to connect the plug sockets of headphones, what are the internal basic principles, such as not professional technicians, we are particularly unfamiliar with their professional knowledge. Then the following part will introduce how to connect the plug socket of the headphone and its construction principle.
Principle of headphone socket construction
When there is reverse voltage bias outside the headphone socket, the external electric field and the built-in electric field are further strengthened, resulting in reverse saturated current I0 which is not related to the reverse bias voltage within a certain range of reverse voltage. It should not be neglected that the reverse current is closely related to the temperature, and the reverse current doubles for every 10 C rise in temperature. Semiconductor diodes must be used in all electronic circuits of headphone sockets. They play a key role in many circuits. They are widely used. Crystal diodes are a p-n junction formed by p-type semiconductor materials and n-type semiconductor materials. Space charge layers are formed on both sides of the interface and self-built electric fields are built. When the applied voltage is not found, the external diffusion current caused by the difference of carrier concentration on both sides of the p-n junction is the same as the drift current caused by the construction electric field, so it is in the electric equilibrium. When there is a forward voltage reference point outside, the suppression effect between the external electric field and the construction electric field increases the external diffusion current of carriers, resulting in the forward current.
Connection Method of Headphone Socket Plug
The audio line of the headphone socket is usually composed of two data signals and three stereo audio lines.
The grounding wire inside the headphone socket plug is usually connected to the root of the innermost power plug. The same tone of the two channels is connected here. The right ear is connected to the end of the middle part, that is, the line marked R on the headphone (the right channel is usually expressed as R+), the part marked L on the left ear is connected to the outermost power plug, and the line marked L on the headphone (the left channel is usually expressed as L+).
