What are the advantages of headphone jacks?

Nov 21,2022

　　Headphone jacks are very commonly used in daily life. There are differences in the specifications and classifications of headphone jacks. In addition, current headphone jacks have different structural designs with 5.1-channel audio and high fidelity, and also have multiple functional options. The contact terminals of the headphone jack adopt an elastic structure design to ensure good and stable contact and service life. So, let's learn about the advantages of headphone jacks!

　　Four Major Advantages of Headphone Jacks

　　Advantage 1

　　In circuits, headphone jacks often have numbers marked on them to represent inductance. The inductor coil is made of insulated wires with a certain number of turns on an insulated frame. Direct current can pass through the coil, and the DC resistance is the resistance of the wire itself, with a small voltage drop.

　　Advantage 2

　　Currently, headphone jacks have different structural designs with 5.1-channel audio and high fidelity, and also have multiple functional options. The contact terminals of the headphone jack adopt an elastic structure design to ensure good and stable contact and service life.

　　Advantage 3

　　When an AC signal passes through the headphone jack, a self-induced electromotive force is generated at both ends of the coil. At this time, the direction of the self-induced electromotive force of the headphone jack is opposite to the direction of the applied voltage. Therefore, the characteristic of the inductance changes from DC resistance to AC. The higher the frequency, the greater the impedance of the coil.

　　Advantage 4

　　Headphone jacks can withstand a soldering temperature of 10S and a plunger force of 3~20N during the soldering process. It is said that headphone plugs made of certain materials can withstand a larger current density rather than a larger current intensity. In addition, the current intensity that can be withstood also varies depending on the thickness of the wire.

　　Advantage 5

　　Headphone jacks mainly support wireless phones, learning machines, mobile phone stereo designs, and other various digital voice devices.

　　Headphone Jack Audio Output Mode

　　After entering the headphone jack audio output mode, the headphone jack's (line input) and (microphone input) follow immediately. The jack becomes the output for the center and subwoofer. After testing the connected speakers and verifying that the speakers and headphone jack are correctly connected, each channel and speaker connected to the headphone jack in the "Audio Manager" panel works correctly.
