Abstract

An apparatus for providing feedback on a user input and a method of providing the same are provided. The apparatus includes: a user input receiver which receives a user input; a signal generator which generates a composite signal including at least one of a sound signal and a vibration signal; a thin film speaker which is attached under the user input receiver and generates a feedback signal on the user input according to the composite signal generated by the signal generator; and a controller which controls the signal generator to compose the sound signal and the vibration signal.

Claims

1. An apparatus for providing feedback on a user input, the apparatus comprising:

a user input receiver which receives a user input;

a signal generator which generates a composite signal comprising at least one of a sound signal and a vibration signal;

a thin film speaker which generates a feedback signal on the received user input according to the composite signal generated by the signal generator; and

a controller which controls the signal generator to compose the sound signal and the vibration signal according to the received user input.

2. The apparatus according to claim 1, wherein the user input receiver is a touch screen or a touch pad.

3. The apparatus according to claim 1, wherein the thin film speaker is attached to the user input receiver under the user input receiver.

4. The apparatus according to claim 1, wherein the composite signal comprises at least one of a high-frequency signal corresponding to the sound signal and a low-frequency signal corresponding to the vibration signal.

5. The apparatus according to claim 1, wherein the thin film speaker vibrates the user input receiver to play sound using the sound signal, and vibrates the user input receiver to provide a vibration feedback signal on the received user input using the vibration signal.

6. The apparatus according to claim 1, wherein the thin film speaker vibrates the user input receiver to provide at least one of a sound feedback signal and a vibration feedback signal on the received user input, using the sound signal.

7. The apparatus according to claim 1, wherein the controller controls the signal generator to modulate at least one of an amplitude and a frequency of the composite signal to adjust an intensity of the composite signal.

8. The apparatus according to claim 1, wherein the controller controls the signal generator so that the thin film speaker generates a feedback signal corresponding to at least one of the sound signal and the vibration signal.

9. The apparatus according to claim 1, wherein the thin film speaker simultaneously outputs a vibration feedback signal and a sound feedback signal, according to the composite signal generated by the signal generator.

10. The apparatus according to claim 1, wherein the thin film speaker separately outputs a vibration feedback signal and a sound feedback signal, according to the composite signal generated by the signal generator.

11. A method of providing feedback on a user input, the method comprising:

receiving a user input;

controlling to generate a composite signal comprising at least one of a sound signal and a vibration signal according to the received user input; and

generating a feedback signal on the received user input according to the composite signal.

12. The method according to claim 11, wherein the receiving the user input comprises receiving the user input from a touch screen or a touch pad.

13. The method according to claim 11, wherein the generating the feedback signal comprises generating the feedback signal through a thin film speaker.

14. The method according to claim 13, wherein the thin film speaker is attached under a touch screen or a touch pad.

15. The method according to claim 11, wherein the composite signal comprises at least one of a high-frequency signal corresponding to the sound signal and a low-frequency signal corresponding to the vibration signal.

16. The method according to claim 11, wherein the generating the feedback signal comprises vibrating a touch screen or a touch pad to play sound using the sound signal, and vibrating the touch screen or the touch pad to provide a vibration feedback signal on the received user input using the vibration signal.

17. The method according to claim 11, wherein the generating the feedback signal comprises vibrating a touch screen or a touch pad to provide at least one of a sound feedback signal and a vibration feedback signal on the received user input using the sound signal.

18. The method according to claim 11, wherein the controlling to generate the composite signal comprises modulating at least one of an amplitude and a frequency of the composite signal to adjust an intensity of the composite signal.

19. The method according to claim 11, wherein the generating the feedback signal comprises generating the feedback signal corresponding to at least one of the sound signal and the vibration signal.

20. A computer readable recording medium having recorded thereon a program executable by a computer for performing the method of claim 11.

21. A method of providing feedback on a user input, the method comprising:

controlling to generate a composite signal comprising at least one of a sound signal and a vibration signal according to a received user input; and

generating, by a thin film speaker, a feedback signal on the received user input according to the composite signal,

wherein the thin film speaker is capable of outputting a sound feedback signal and a vibration feedback signal according to the generated composite signal.

22. A computer readable recording medium having recorded thereon a program executable by a computer for performing the method of claim 21.
