Abstract

An apparatus and method for generating pulsating noise in an audio device are provided. The apparatus and method mix audio signals processed by an audio play operation with pulsating noise generated by a pulsating noise generator if a brain wave induction mode is set in an audio device and output a result of the mixing operation through wired or wireless speaker. Therefore, a user can efficiently experience brain wave induction action based on the pulsating noise while he/she hears audio from the speaker.

Claims

1. An apparatus for generating pulsating noise in an audio device, comprising:

an audio unit including an audio signal processing unit configured to process audio data;

a pulsating noise generator configured to generate pulsating noise at a predetermined frequency; and

a mixing unit, wherein the mixing unit mixes an audio signal processed by the audio signal processing unit with the pulsating noise generated by the pulsating noise generator.

2. The apparatus as set forth in claim 1, wherein the pulsating noise generator is further configured to generate various sound sources.

3. The apparatus as set forth in claim 1, wherein the pulsating noise generator is mounted within a communication transmission module connected to the audio unit.

4. The apparatus as set forth in claim 3, wherein the communication transmission module comprises a Bluetooth transmission module.

5. The apparatus as set forth in claim 3, wherein the pulsating noise generator is controlled by a user input through an input device.

6. The apparatus as set forth in claim 3, wherein the audio unit further comprises a controlling unit configured to control operation of the pulsating noise generator based on a user request.

7. The apparatus as set forth in claim 1, wherein the pulsating noise generator is mounted within the audio unit.

8. An audio device comprising the apparatus for generating pulsating noise of claim 1.

9. A DVD player comprising the audio device of claim 8.

10. A method for generating pulsating noise in an audio device, comprising;

confirming whether a brain wave induction mode is set if an audio play operation is requested;

generating pulsating noise if there is a confirmation indicating that the brain wave induction mode is set; and

mixing the pulsating noise with an audio signal processed by the audio play operation.

11. The method as set forth in claim 10, further comprising:

receiving a user request via an input device; and

determining whether an audio play operation is requested.

12. The method as set forth in claim 10, further comprising:

determining whether a brain wave induction operation is requested, if an audio play operation is not requested; and

generating pulsating noises and/or specific sound sources selected by a user, if a brain wave induction operation is requested.

13. The method as set forth in claim 10, wherein the method is implemented in an audio device of a DVD player.

14. An apparatus for generating pulsating noise for use with an audio device, comprising:

a pulsating noise generator configured to generate pulsating noise at a predetermined frequency, the pulsating noise being designed to induce a brain wave of a user corresponding to the predetermined frequency; and

electronic communication means for providing electronic communication with an audio device.

15. The apparatus as set forth in claim 14, wherein the electronic communication means comprises wireless communication means.
