The construction principle and wiring method of headphone plug and socket will be introduced in detail. What details do we have? We will give you a detailed introduction below.
Earphone plugs and 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 earphone plugs and sockets, what are the internal basic principles, such as not professional technicians, we also know about this professional knowledge. It's especially strange. 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 the 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 there are two kinds of junctions. Self-built electric field. 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 of the outermost power plug on the left ear, and the line marked L on the headphone (the left). The vocal tract is usually expressed as L+.
