ELECTRONIC DEVICE |
摘要 |
An electronic device includes a vibration unit configured to generate a vibration sound transmitted by vibrating a contacting or pressing body part; and piezoelectric elements stacked on and attached to the vibration unit and vibrating the vibration unit in accordance with an input signal. The piezoelectric elements each have a different capacitance. Voltage of the input signal to the piezoelectric elements is varied in accordance with frequency band, thereby suppressing power consumption. |
