<P>PROBLEM TO BE SOLVED: To provide a wearable communication device which can be used in such a portion that the communication device doesn't give fatigue or a sense of incongruity to a user, and is superior in environment resistance. <P>SOLUTION: The wearable communication device has a structure where a vibrator for outputting a sound signal is installed in a part of a ring and an acoustic output from the vibrator is heard through a hollow tubular portion provided in the ring or a narrow tube provided along the outer periphery of the ring and from an opening part of the tube provided in a position diametrically opposed to the position of the vibrator or in a position spaced from the vibrator. A circuit part, a battery, and the vibrator are formed into one body, and a sealing structure is given to them with a resin or the like to improve reliability, and a coupling part is provided between the vibrator and the tube to improve efficiency. <P>COPYRIGHT: (C)2004,JPO |
