Hearing system and finger ring for the hearing system

A finger ring used for a hearing system, comprising:

• a short-distance wireless communication portion;
• a vibration output portion disposed at a position that contacts a finger to convert a voice signal, which is received by the short-distance wireless communication portion, into a cartilage conduction vibration and outputs the cartilage conduction vibration;
• and
• a power source portion that performs electric power supply to the short-distance wireless communication portion and the vibration output portion,
• wherein the vibration output portion includes a piezoelectric bimorph;
• and
• wherein the power source portion includes a voltage step-up circuit that drives the piezoelectric bimorph.

A finger ring used for a mobile phone system as a hearing system, comprising:

• a short-distance wireless communication portion;
• a vibration output portion disposed at a position that contacts a finger to convert a voice signal, which is received by the short-distance wireless communication portion, into a cartilage conduction vibration and outputs the cartilage conduction vibration;
• a power source portion that performs electric power supply to the short-distance wireless communication portion and the vibration output portion;
• a control portion that receives an incoming signal via the short-distance wireless communication portion to make the power source portion start the electric power supply;
• and
• an incoming alert vibration portion that notifies a phone call based on the incoming signal.
