Abstract:
An apparatus includes a signal device, a power amplifier, and a sound wave generator. The power amplifier is electrically connected to the signal device. The power amplifier outputs an amplified electrical signal to the sound wave generator. The sound wave generator produces sound waves by a thermoacoustic effect. The amplified electrical signal is positive or negative.
