Abstract: Provided is a glasses-type acoustic device which obviates the need for lead wires for transmitting a signal or supplying power between the temple on the first or first side and the temple on the second side, thereby eliminating the need for a complex wiring, and further, allowing development thereof as commodities having a variety of designs. The glasses-type acoustic device includes electronic circuits and sound generating devices, which are incorporated in temples on the second and first sides, respectively; an electric cell that drives an electronic circuit in the temple on the second side is built in a drop end on the second side; and an electric cell that drives an electronic circuit in the temple on the second side is built in a drop end on the first side.
