Abstract
The present technology relates to an audio device and a driving method thereof, and a display device which are configured to make it possible to obtain sufficient sound pressure level in a wider frequency band. The audio device includes: a diaphragm; an electrodynamic vibrator that vibrates the diaphragm to output sound; and a piezoelectric vibrator that vibrates the diaphragm to output sound. The present technology can be applied to the display device.
Claims8
An audio device comprising:
- a diaphragm;
- an electrodynamic vibrator that vibrates the diaphragm to output sound;
- a piezoelectric vibrator that vibrates the diaphragm to output sound;
- an LPF that performs filtering to block a high frequency band component on an acoustic signal;
- and
- an HPF that performs filtering to block a low frequency band component on the acoustic signal,
- wherein the electrodynamic vibrator vibrates the diaphragm on a basis of a signal obtained by the LPF, and
- the piezoelectric vibrator vibrates the diaphragm on a basis of a signal obtained by the HPF.
