Abstract: Provided is a wearable device that is worn on a human ear and mainly outputs or inputs sound. The outer casing 110 is formed into an elongated shape so as to fit the cymba conchae 306 formed between the antihelix inferior crus 302b and the crus helicis 309. The sound generating unit 120 includes a vibration element 121 and a weight 122. The vibration element 121 has an elongated shape along the longitudinal direction of the outer casing 110, and has one end fixed to the inner wall of the outer casing 110, and the other end to which a weight 122 is attached, the other hand being an open end. By applying an alternating electric field to the vibration element 121, vibration corresponding to audio is generated.
