Abstract

An electronic apparatus includes a configured to output audio using a permanent magnet, an audio processor configured to process audio data and output to the speaker, and an electromagnet configured to push the permanent magnet and project the speaker out on the electronic apparatus, with application of electric current.

Claims

1. An electronic apparatus comprising:

a speaker configured to output audio using a permanent magnet;

an audio processor configured to process audio data and output to the speaker; and

an electromagnet configured to push the permanent magnet and to project the speaker out of the electronic apparatus by pushing the permanent magnet, with application of an electric current; and

a controller to sense a position of a user, to determine a degree of the projection of the speaker based on the sensed position of the user, and to determine flow of the electric current through the electromagnet based on the determined degree of the projection of the speaker.

2. The electronic apparatus of claim 1, wherein the speaker comprises:

a housing in which one side is connected to the electronic apparatus with a hinge, and another side extends to a distance from the electronic apparatus; and

a speaker module arranged within the housing to output the audio using the permanent magnet.

3. The electronic apparatus of claim 2, wherein the housing is buried in the electronic apparatus to an extent of being in a parallel relationship with a surface of the electronic apparatus, when the electric current is not input to the electromagnet.

4. The electronic apparatus of claim 1, wherein the electromagnet is arranged at a position on a circuit board to correspond to the permanent magnet.

5. The electronic apparatus of claim 4, wherein the electromagnet comprises one of a solenoid and a superconductive magnet.

6. The electronic apparatus of claim 4, wherein the circuit board comprises a plurality of layers, and the electromagnet comprises a coil pattern of a plurality of layers on the circuit board.

7. The electronic apparatus of claim 1,

wherein the electromagnet comprises an iron core, and

wherein the speaker is buried within the electronic apparatus when the electric current is not input to the electromagnet, as the permanent magnet pulls the iron core.

8. The electronic apparatus of claim 1, further comprising a plurality of speakers and a plurality of electromagnets corresponding to the plurality of speakers, respectively, and

wherein the audio processor outputs the audio data to the plurality of speakers.

9. The electronic apparatus of claim 8, further comprising a controller configured to individually control whether the plurality of electromagnets is operated.

10. The electronic apparatus of claim 1, further comprising a controller configured to control whether the electromagnet is operated.

11. The electronic apparatus of claim 10, wherein the controller is configured to control the electromagnet operate upon receiving of one or more of a control command from a user and a preset program.

12. The electronic apparatus of claim 10, wherein the controller projects the speaker to a predetermined height by allowing the electric current in an amount corresponding to a user set value and a preset condition to flow on the electromagnet.

13. A method of providing sound in an electronic apparatus comprising at least one speaker, the sound providing method comprising:

processing audio data;

outputting the processed audio data to the at least one speaker;

sensing a position of a user;

determining a degree of projection of the at least one speaker based on the sensed position of the user;

determining an electric current which flows through an electromagnet based on the determination of the degree of projection of the at least one speaker; and

projecting the at least one speaker out on the electronic apparatus, using the electromagnet to push a permanent magnet of the speaker upon application of the current.

14. The method of claim 13, further comprising:

pulling, by the permanent magnet, an iron core to bury the speaker within the electronic apparatus, in an absence of the electric current on the electromagnet.

15. The method of claim 13, wherein the electronic apparatus comprises a plurality of speakers and a plurality of electromagnets corresponding to the plurality of speakers, respectively, and

the outputting of the processed audio data comprises outputting the audio data to the plurality of speakers.

16. The method of claim 15, wherein the projecting of the at least one speaker comprises individually controlling the plurality of electromagnets, and individually projecting the plurality of speakers, respectively.

17. The method of claim 13, wherein the projecting of the at least one speaker comprises projecting the at least one speaker out of the electronic apparatus based on one or more of a user control command and a preset program.

18. The method of claim 13, wherein the projecting of the at least one speaker comprises projecting the at least one speaker to a preset height, by allowing the electric current to flow to the electromagnet in an amount corresponding to a user set value and a preset condition.

19. An electronic apparatus with a casing, comprising:

at least one speaker including a permanent magnet and configured to move between being disposed within the casing and projecting from the casing;

an electromagnet disposed within the casing and configured to create a repulsive force with the permanent magnet to force the speaker to project from the casing when an electric current is applied thereto; and

,

a controller to sense a position of a user, to determine a degree of projection of the at least one speaker based on the sensed position of the user, and to determine the electric current which flows through the electromagnet based on the determination of the degree of projection of the at least one speaker.
