Abstract
An intra-concha type electroacoustic trasducer has an auxiliary supporter projecting in opposite direction to entrance part of external auditory meatus of the user's ear from a side of the transducer opposite to its sound-radiating side disposed to face the auditory meatus entrance. Reliable mountability of the transducer with respect to auricle of the user's ear is thereby ensured, while an unpleasantness or pain given to the user upon mounting to the auricle can be at least reduced to a remarkable extent.
