An acoustic device (100) having: frames (120); cases (110) affixed to the frames and having earmuff parts (150), and housing acoustic generation units; and a headband (130) connected to the frames. Spaces (R) are formed between the frames and the cases for hanging on the user's ears. Thus, it is possible to provide an acoustic device that can be worn over the head or worn as a neckband, without providing a movable mechanism. |
