Abstract
An in-ear type earphone according to the present invention includes an in-ear type speaker element and a cable disposed externally of the earphone. The cable is coupled at one end to the speaker element such that the cable hangs freely from the speaker element. The opposite end of the cable is coupled to a plug. The plug operatively connects the earphone to a sound signal source. A sliding round shaft is rotatably mounted at one end of the speaker element. A sliding sleeve receives an opposite end of the sliding round shaft and allows it to move along a longitudinal axis. The earphone also has an ear hanger with a helix stopper end, a curved hook section, and a lobule stopper end integrally formed and contoured to the general shape of a human ear. The helix stopper end is mounted to the sliding sleeve in a fixed manner.
