PROBLEM TO BE SOLVED: To provide an ear attaching type calling device for reducing an influence of electromagnetic waves. SOLUTION: The ear attaching type calling device 1 is an ear attaching type calling device which is attached to an ear of a person and has a main body having a circuit board 6 and an antenna 9 for carrying out radio communication. The calling device 1 has an earphone 3 extending from the main body 1 and attached to an ear shell cavity 61 of an ear for outputting voice or speech to the ear shell cavity 61. The calling device 1 has a microphone portion 4 extending from the main body 2 and attached in contact with the ear shell cavity 61 for detecting a bone conductive voice or speech transmitted to the ear shell cavity. In this constitution, the circuit board 6 and an antenna 9, which may generate electromagnetic waves, can be separated from a user's head. COPYRIGHT: (C)2004,JPO&NCIPI
