A TRS connector (tip, ring, sleeve) also called an audio jack, phone plug, jack plug, stereo plug, mini-jack, mini-stereo, or headphone jack, is a common analog audio connector. It is cylindrical in shape, typically with three contacts, although sometimes with two (a TS connector) or four (a TRRS connector).It was invented for use in telephone switchboards in the 20th century and is still widely used, both in its original ¼″ (exactly 6.35 mm) size and in miniaturized versions: 3.5 mm (approx. â...›â€³) and 2.5 mm (approx. 3/32″). The connector''s name is an initialism derived from the names of three conducting parts of the plug: Tip, Ring, and Sleeve – hence, TRS.
