Abstract
A driving circuit for an acoustic printer and an acoustic printer which enables high speed and high image quality recording and is reduced in size and cost. An inductance switching circuit connected in parallel to an electrostatic capacity included in a piezoelectric element is connected to an amplifying part. The inductance switching circuit and the electrostatic capacity form a parallel resonance circuit called TANK circuit. The inductance switching circuit is formed by two inductances and switches connected in series to the respective inductances, and the inductances are connected in parallel. The switches are externally controllable.
