Abstract
A cycling hearing device has: a stereo sound source unit; left and right vibration sources which conduct a stereo sound source from the stereo sound source unit to the left and right ears respectively without closing either of the left and right external auditory meatus; a notifier that notifies publicly that the left and right external auditory meatus are not closed; a helmet part; and a chin strap part fitted to the helmet part. The left and right vibration sources are cartilage conduction vibration sources respectively. The vibration sources are provided in the chin strap part, and the notifier is an external appearance structure in which the vibration sources conduct vibration to the ear cartilage without closing the external auditory meatus.
