Abstract:
To enhance user friendliness by making state change recognizable visually from the outside.
The headphone includes a head band which includes a shape change part formed by laminating a plurality of layers, each including a surface layer having a notch and a back layer not having a notch, and a speaker unit which is attached to the shape change part from the back layer side. When the shape change part is pressed against the speaker unit, the shape change part is projected to the surface layer side and the notch is opened. Since state change can be recognized visually from the outside due to the change in the shape of the shape change part, user friendliness can be enhanced.
