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 project the speaker to extent out of the electronic apparatus, with application of electric current.

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 the other 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 the 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 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 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 so that the electromagnets operate upon receiving of a user'"'"'s control command or driving of a preset program.

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

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; and

projecting the at least one speaker out on the electronic apparatus, suing ‘

electromagnet pushing permanent magnet of the speaker upon application of electric current’

.

14. The method of claim 13, further comprising:

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

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 comprises outputting the audio data to the plurality of speakers.

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

17. The method of claim 13, wherein the projecting comprises projecting the speakers out of the electronic apparatus when a user control command is input or when a preset program is driven.

18. The method of claim 13, wherein the projecting comprises projecting the speakers to a preset height, by allowing electronic current in a size corresponding to a user set value and a preset condition to flow to the electromagnets.

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; and

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.

20. The electronic apparatus of claim 19, further comprising:

a controller to sense a position of a user, to determine a degree of projection of the at least one speaker based on the determined position, and to determine an electric current to flow through the electromagnet based on the previous determinations.
