• wherein:
• the main body has a shape of a pen,
• a base of the clip portion penetrates a chassis of the main body,
• one end of the clip portion is located outside the chassis and another end of the clip portion is located inside the chassis,
• a vibration insulating material which is an elastic body is disposed between the chassis and the base,
• the clip portion is formed of a rigid body,
• the cartilage-conduction vibration source and the resilient metal member are arranged inside the chassis of the main body,
• the cartilage-conduction vibration source is located away from an inner wall of the chassis of the main body,
• the cartilage-conduction vibration source is supported on the clip portion,
• the resilient metal member is connected to the cartilage-conduction vibration source,
• the clip portion is configured to be openable-closable,
• when the clip portion is closed, a part of the clip portion located away from the base makes contact with the main body and the resilient metal member is located away from the chassis of the main body, and
