What is a mini plug?

The mini plug is a plug of 3.5 mm (1/8 inches) that connects an audio or video device with an external output such as speakers or headphones. Mini plugs are also used to input the microphone. Mini plugs are technically called TRS connectors because they use three parts - tip, ring and sleeve (TRS) - to make sound. They are also called sound connectors, stereo jacks, stereo connectors, headphone connectors, jack connectors and mini-jacks. Any variation of "plug" is more accurate than "jack", because "jack" usually refers to the socket to which plug goes. Originally, the tip and annular part of the plug served different features in the phone calls: the tip carried the sound of the bell and voice of the phone, while the ring carried a busy signal. Telephone switchboards are largely a thing of the past, but both larger plugs and mini plugs have become standard video and sound equipment. An even smaller 2.5mm plug, sometimes called the backlighting plug, is often used with headphones, ear buds andHands-free for mobile phones.

Depending on the number of wires it has, the mini plug can supply mono or stereo sound or even video. mono means there is only one sound channel; The sound is the same in both speakers or both headphone headphones. Mini plugs with two wires carry a mono signal. stereo means there are two channels, so the sound in each speaker is different, but it is mixed to hear the user together. The stereo signal is transmitted by a three -wire mini plug. Mini plugs with four wires give a stereo signal plus video.

mini plugs are used for output with most modern sound devices, from portable audio players and DVD players to mobile phones, computers and stereos. One particle use is with a training software that uses sound tones to control ElElectronic exercise devices such as treadmills. Mini plugs are used to enter through a microphone with cameras, computers and sound recorders. Professional sound recording devices are more likely to use 1/4 inch plugs than mini plugs and top consumer equipment often also uses larger plugs. Using a second -size drawer can be used by both sizes using an adapter; These adapters can easily be found in most stores that carry home electronics.
