Speaker apparatus and electronic device having the same
A speaker apparatus and an electronic device having the same are provided. The speaker apparatus includes a hollow shape frame, a magnet disposed in an internal part of the hollow shape frame, a voice coil installed in proximity to the magnet, a diaphragm including a diaphragm edge that vibrates by an electric current applied to the voice coil, and a diaphragm edge compression part extended upward along the diaphragm edge. The diaphragm edge compression part contacts an inner surface of a housing of the electronic device.
1. A speaker apparatus comprising:
a hollow shape frame;
a magnet disposed in the hollow shape frame;
a voice coil disposed in proximity to the magnet;
a diaphragm installed on one side of the voice coil, the diaphragm configured to vibrate by an electric current applied to the voice coil;
a diaphragm edge disposed in the diaphragm; and
a diaphragm edge compression part extended along the diaphragm edge having at least a portion extended upward at a pre-determined height above the diaphragm edge,
wherein the diaphragm edge compression part contacts an inner surface of a housing of an electronic device.
2. The speaker apparatus of claim 1 , wherein the diaphragm edge compression part is disposed on an upper part of the hollow shape frame.
3. The speaker apparatus of claim 2 , wherein a bottom surface of the diaphragm edge compression part has a recess coupling with a portion of the hollow shape frame.
4. The speaker apparatus of claim 3 , wherein an upper part of the hollow shape frame has a guide rib fitted into the recess of the diaphragm edge compression part.
5. The speaker apparatus of claim 1 , wherein a lateral surface of the diaphragm edge compression part contacts a support rib formed in the inner surface of the housing of the electronic device.
6. The speaker apparatus of claim 5 , further comprising:
an enclosure upper case; and
an enclosure lower case,
wherein the enclosure upper case accepts the hollow shape frame, and is coupled with the enclosure lower case to form a sound resonance space.
7. The speaker apparatus of claim 6 , wherein an inner surface of the enclosure upper case has a safe mounting part for safely mounting the hollow shape frame.
8. The speaker apparatus of claim 7 , wherein an inner surface of the enclosure lower case has a support boss supporting the hollow shape frame in a height direction.
9. The speaker apparatus of claim 1 , wherein at least another portion of the diaphragm edge compression part does not extend upward at the pre-determined height above the diaphragm edge.
10. The speaker apparatus of claim 1 , wherein the diaphragm edge and the diaphragm edge compression part are integrally formed.
11. An electronic device comprising:
a housing comprising a speaker hole;
a hollow shape frame disposed in the electronic device, and having a hollow portion formed in a position corresponding to the speaker hole;
a magnet disposed in the hollow shape frame;
a voice coil installed in proximity to the magnet;
a diaphragm installed on one side of the voice coil, the diaphragm configured to vibrate by an electric current applied to the voice coil;
a diaphragm edge disposed in the diaphragm; and
a diaphragm edge compression part extended along the diaphragm edge having at least a portion extended upward at a pre-determined height above the diaphragm edge,
wherein the diaphragm edge compression part contacts an inner surface of the housing.
12. The electronic device of claim 11 , wherein the diaphragm edge compression part is disposed on an upper part of the hollow shape frame.
13. The electronic device of claim 12 , wherein a bottom surface of the diaphragm edge compression part has a recess coupling with a portion of the hollow shape frame.
14. The electronic device of claim 13 , wherein an upper part of the hollow shape frame has a guide rib fitted into the recess of the diaphragm edge compression part.
15. The electronic device of claim 11 , wherein a lateral surface of the diaphragm edge compression part contacts a support rib formed in the inner surface of the housing of the electronic device.
16. The electronic device of claim 15 , further comprising:
an enclosure upper case; and
an enclosure lower case,
wherein the enclosure upper case accepts the hollow shape frame, and is coupled with the enclosure lower case to form a sound resonance space.
17. The electronic device of claim 16 , wherein an inner surface of the enclosure upper case has a safe mounting part for safely mounting the hollow shape frame.
18. The electronic device of claim 17 , wherein an inner surface of the enclosure lower case has a support boss supporting the hollow shape frame in a height direction.
19. The electronic device of claim 11 , wherein at least another portion of the diaphragm edge compression part does not extend upward at the pre-determined height above the diaphragm edge.
20. The electronic device of claim 11 , wherein the diaphragm edge and the diaphragm edge compression part are integrally formed.
