Abstract
An audio output apparatus is provided. The audio output apparatus includes: a vibration member, a vibrator, a vibrator positioning unit, and a vibrator-depth positioning unit. The vibration member vibrates to output a sound. The vibrator is in contact with the vibration member and detachably attached thereto to allow the vibration member to vibrate in response to an input audio signal. The vibrator positioning unit controls a contact position between the vibrator and the vibration member. The vibrator-depth positioning unit adjusts a position of the vibrator in the direction of being pressed against the vibration member and brought into contact with the vibration member.
