Abstract

An electro-acoustic transducer having a main body portion 4 housing at least a speaker unit, a pinna inserting portion 5 protruding from the main body portion and adapted for being inserted into a pinna of a user, an elastically deformable auditory canal fitting portion 12, 51 provided on the outer periphery of the pinna inserting portion and an insertion control portion 46, 52 for controlling an insertion position of the auditory canal fitting portion 12, 51 into the auditory canal. By inserting the pinna inserting portion 5 into the pinna, the auditory canal fitting portion 12, 51 is deformed to conform to the shape of the auditory canal and fitted in the auditory canal in this state for hermetically sealing the auditory canal. The insertion control portion 46, 52 is retained by a portion of the pinna for controlling the inserting position of the auditory canal fitting portion 12, 51 in the auditory canal. The electro-acoustic transducer may be attached in a stable state with optimum attachment feeling for any user to enable the playback sound to be heard with satisfactory acoustic characteristics.
