PURPOSE:To obtain an acoustic transducer used for both an ear-hanging type and an ear hole mounting type with simple operation by allowing the acoustic transducer having a small diameter possible for being mounted in an ear hole to be coupled with a holding means to an earlobe. CONSTITUTION:A speaker part 7 used for an ear-hole type receiver is inserted to a buckle 9 having an insertion hole and mounted at the back of the earlobe by a ring form pad 10. The pad 10 clips the earlobe together with the buckle 9 to fix the buckle 9 to the ear. Further, the buckle 9 and the pad 10 are connected together with the freedom of turning by means of a pin 11. In using the transducer as the ear hole type receiver, the speaker part 7 is used singly. |
