Headphone jacks are also a relatively common type of electronic socket component. Currently, audio equipment, televisions, MP3s, mobile phones, instruments and equipment all require headphone jacks, so there are many details to pay attention to when using them.
1. Headphone Socket Wiring Method
There are generally several wiring methods for headphone sockets. The first is the three-section headphone socket. The standard wiring generally connects the left channel, right channel, and ground wire. However, due to the large number of specifications of some headphone sockets, the specifications of the five-pin headphone socket are generally used for power amplifier equipment (audio equipment). The wiring pin 1 still corresponds to the ground pin, and the 2nd and 3rd pins correspond to the left channel output and the speaker line. The last 4th and 5th pins can be connected to the right channel output and the speaker line respectively.
2. Precautions for using the headphone socket
1. When using the headphone socket, you cannot use other three-stage or four-stage headphone sockets instead, because if the wiring requirements of the headphone socket used by the power amplifier device are not met, other specifications of the headphone socket are not compatible;
2. Regarding the wiring of the headphone socket, do not connect the 2nd and 3rd pins, and the 3rd and 4th pins to each other, otherwise it will cause the problem of no sound when using the headphone socket;
3. When using the headphone socket, pay attention to prevent the intrusion of water vapor, otherwise it will cause a short circuit, etc. , which will cause noise or silence when using the headphone socket;
4. The headphone socket has a distinction between the national standard and the American standard wiring. Before operating the headphone socket, you must first understand whether the corresponding specification manual is the national standard or the American standard connection method, so as to avoid the wrong connection of the headphone socket;
5. When connecting the headphone socket and the plug, you should also pay attention not to pull out or connect with too much force. If the plugging is too strong, it will cause the metal chip inside the headphone socket to wear, and it will also easily cause the connection between the headphone socket and the plug to become loose.
