Translationsearphone
earphone a device for converting electric currents into sound waves, held close to or inserted into the ear Earphone a miniature device for listening to dictaphone and magnetic tape recordings, radio broadcasts, and the simultaneous translation of speeches. Earphones are similar in purpose to headphones. They contain one or two miniature electromagnetic or piezoelectric transducers, which convert electrical oscillations into an acoustic signal, and extensible acoustic conductors; the latter are connected to the transducers and have plastic tips that are placed in the ear. Unlike headphones, earphones do not have a headband that grasps the upper part of the head and are therefore more convenient to use. earphone[′ir‚fōn] (engineering acoustics) An electroacoustical transducer, such as a telephone receiver or a headphone, actuated by an electrical system and supplying energy to an acoustical system of the ear, the waveform in the acoustical system being substantially the same as in the electrical system. A small, lightweight electroacoustic transducer that fits inside the ear, used chiefly with hearing aids. earphoneAn electronic device by which acoustic signals are received. Earphones are a part of headsets and helmets used by aircrew and passengers. A more technical definition—it is an electroacoustic transducer converting an electrical signal to an acoustical signal, which is intended to be closely coupled acoustically to the ear.earphone
