To get unbalanced mono, the sleeve acts as the ground/return wire while the tip carries the audio signal with the ring being an option to carry the mic signal. To get unbalanced stereo signals, the sleeve serves as the ground/return wire while the ring acts as the right audio channel and the tip to act as the left audio channel. To achieve balanced mono, the sleeve acts as the return wire while the ring acts as the negative signal and the tip as the positive signal. Sleeve: This acts as the common return wire Ring: This acts as the right channel signal wire Tip: This acts as the left channel signal wire The ring which serves as a conductor introduces the possibilities of balanced or unbalanced mono and stereo signals. 3 Conductor Plugs/TRS TRS connectors have 3 conductors. TS connectors are mostly found in 2.5 mm sizes and are mostly used with guitars and instruments. If the cord is long, there is a greater chance of distortion – this is because the sleeve picks up noise along the way just as an antenna does. TS connectors work best in short cable connections.
The sleeve serves as a ground and return path while the tip transmits the audio signal. The two-conductor plug allows audio signal to be transmitted in mono. There are various phone connectors, in this section we shall explore the available plug connectors. That means that the ¼ inch plug sleeve diameter is 6.35 mm, similarly miniature and sub-miniatures sleeve diameters are 3.5 mm and 2.5 mm respectively. When naming plugs, the outer diameter of the sleeve conductor determines its name. The number of rings in a plug determine the plugs toponomy.Īnother interesting point is that ring and sleeve contacts have the same diameter. The black bands separate the conductors and prevented them from being shorted together. Sleeve (S) –> While this can be confused with a ring, it is usually longer than a ring and it also determines the diameter of the connector.Īll headphone plugs have at least two conductors tip and sleeve. Ring (R) –> Separates the tip and sleeveģ. Tip (T) –> This is the tip of the connectorĢ. To achieve compatibility, two things are considered in the headphone jack and plug size and wiring schematic.Īs mentioned earlier, headphone plugs have 2 to 5 conductors. While some headphone plugs and jacks might look familiar, it is important to point out that they might not be compatible. All headphone plugs and jacks have 2 to 5 conductors. Headphone jacks and plugs are simple – to get audio signals the cords attached to the headphone plugs create an electrical circuit which makes it possible for signal which is in AC to be transmitted to the headphones which then converts the signals to sound.Ī headphone plug and jack contains conductors which act as connection points of the plugs to complete the circuit. The appearance of the headphone plug is round with chisel tips that push a spring-loaded retainer in the jack to hold it in. Note: While most headphone jacks are only capable of transmitting analog audio signals, some headphone jacks have the capability to transmit digital audio signals such as the Google Chromecast.
When you connect a plug to a jack, that connection becomes complete. Digital audio signals pass from a gadget to a headphone through a headphone connector which converts audio from digital to analog. In most design settings, the headphone jack comes installed in an equipment while the headphone plug is usually connected to a cord.
The headphone jack acts as the female connector as it is on the receiving end while the plug acts as a male connector. The headphone jack is usually a small round hollow analog socket while the plug is pin/cylindrical shaped. It is also commonly referred to as phone jack, audio jack, jack plug or phone connector. A headphone jack is an electrical connector used to transmit and receive audio signals.
