Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electroacoustic transducer and its attachment by which noise leaking and hearing loss can be prevented and high acoustic quality and further comfort can be obtained. SOLUTION: The attachment 20 is provided on the side of a speaker S of the electroacoustic transducer 10 of inner ear type. It is made of at least two types of flexible materials exhibiting at least different hardness and/or density and is composed of an intra-aural insertion part 1 which is at least acoustically coupled to an oscillator X performing electroacoustic conversion. The intra-aural insertion part 1 is provided with a sound transmitting opening 2 for transmitting acoustic output from the oscillator X to the inside of an ear E. COPYRIGHT: (C)2008,JPO&INPIT
