There are many headphone jacks in daily use, and there are differences in the specifications of headphone jacks. In addition, the current headphone jack has a structural design with different high fidelity of 5.1-channel audio, and also has a variety of functional options. The contact terminal of the headphone jack adopts an elastic structure design to ensure good and stable contact and service life. So, let's take a look at the advantages of the headphone jack.！

Four advantages of headphone jacks

Advantage 1

Headphone jacks often have numbers on l in the circuit to indicate inductance. The inductor coil is an insulated wire made with a certain number of turns on an insulated frame. DC can pass through the coil. The DC resistance is the resistance of the wire itself, and the voltage drop is small.

Advantage 2

Currently, the headphone jack has a structural design with different audio fidelity for 5.1 channels, and has multiple functional use options. The contact terminal of the headphone jack adopts an elastic structure design to ensure good and stable contact and service life.

Advantage 3

When an AC signal passes through the headphone terminal, a self-induced electromotive force will be generated at both ends of the coil. At this time, the direction of the self-induced electromotive force of the headphone terminal is opposite to the direction of the applied voltage. Therefore, the characteristics of the inductance are converted into AC through DC resistance. The higher the frequency, the greater the impedance of the coil.

Benefit 4

The headphone jack can withstand the welding temperature of 10S and the plunger force of 3~20N during the welding process. It is said that the headphone plug can withstand a larger current density rather than a larger current intensity for a wire made of a certain material. In addition, depending on the thickness of the wire, the intensity of the current that can be sustained at the same time is also different.

Advantage 5

The headphone jack mainly supports wireless phones, learning machines, mobile phone stereo designs and various other digital voice devices.

Headphone jack audio output mode

After entering the audio output mode of the headphone jack, the (line input) and (microphone input) of the headphone jack are followed, and the jack becomes the output of the center and subwoofer. After testing the connected speakers and testing whether the speakers and headphone jacks are correctly connected, each channel and speaker connected to the headphone jack in the "Audio Manager" panel works properly.
