Abstract
Supply of power is ensured on use without requiring troublesome works such as battery replacement work and charging work. Specifically, hearing aids, which collect sound, amplify the collected sound, and output the amplified sound, boosts electromotive force generated by the Peltier module derived from temperature difference between a human-body contact portion and an ambient-air contact portion, and causes sound collecting units, a controller IC, a speaker to operate by the boosted voltage.
