A piezoelectric element driving circuit includes a piezoelectric element, a switching element, and a coil. The piezoelectric element generates at least one of sound and vibration. The switching element turns on/off the application of a voltage to the piezoelectric element at regular intervals. The coil is connected in parallel with the piezoelectric element. A remote controller includes the piezoelectric element driving circuit, a receiving circuit, and a controlling circuit. The receiving circuit receives a signal for searching the remote controller. The controlling circuit is connected to the piezoelectric element driving circuit and the receiving circuit, and operates the piezoelectric element driving circuit when the receiving circuit receives the search signal. |
