Abstract
An improved earphone comprises a housing with a transducer therein. A rod member in fixed connection with the housing is provided along with a separating element which is connected at one end to frictionally slide along the rod member but without rotating relative thereto. A curved lever is provided at the other end of the separating element which has a free end portion to be engaged on the ear. The transducer is spaced an appropriate distance for radiating sound into the ear and can be aligned relative to an angle of the ear without placing excessive pressure on the ear.
