Patent ID: 8892156

Claim:
A mobile terminal comprising: a touch screen; a flat panel sound output unit comprising one or more flat panel speakers within a vibration panel that is configured to provide both sounds and vibrations, said flat panel sound output unit being coupled to a surface of the touch screen, said flat panel sound output unit generates sounds and vibrations according to an input signal; a vibration processor sending, when a touch event occurs at the touch screen, a signal to the flat panel sound output unit, the signal directing the flat panel sound output unit to generate vibrations corresponding to the touch event without a separate vibration motor; and an audio processing unit sending an audio signal to the flat panel sound output unit to produce sounds corresponding to the audio signal; wherein vibration panel of the flat panel sound output unit comprises a transparent vibration panel coupled to an exterior surface of the touch screen, and a vibration member coupled to the vibration panel causing the vibration panel to vibrate, and wherein the at least one of the one or more flat panel speakers of the flat panel sound output unit comprises a piezoelectric speaker employing a piezoelectric film as the vibration member.
