wherein the lighting apparatus is mounted on the light mounting portion.

3. The speaker of claim 1, wherein the lighting apparatus comprises:

a lighting module having a light emitting device; and

a light diffusion portion configured to surround the lighting module in order to diffuse light generated from the light module toward the vibration portion.

4. The speaker of claim 3, wherein the light diffusion portion comprises a prism whose outer surface is curved to allow light generated from the lighting module to reach the vibration portion through dispersion or refraction.

5. The speaker of claim 3, wherein the light diffusion portion comprises a concave convex part provided in a column shape whose outer surface is formed in a convex structure structure.

6. The speaker of claim 5, wherein the concave convex part comprises a ventilation hole provided at an inner side of the concave convex part to radiate heat generated by the light emitting device.

7. The speaker of claim 5, wherein the concave convex part comprises:

a convex portion formed in a protruding manner; and

a concave portion depressed when compared to the convex portion while being formed adjacent to the convex portion,

wherein one of the convex portion and the concave portion is opaque and the remaining portion is transparent.

8. The speaker of claim 3, wherein the lighting apparatus further comprises:

a support configured to have a lower portion of the light diffusion portion mounted thereon, the support configured to be mounted and fixed to the center of the vibration portion.

9. The speaker of claim 8, wherein the support includes heat resistant material.

10. The speaker of claim 8, wherein the support comprises a support tube having a wire hole which allows a wire transmitting electrical signals to the light emitting device to pass there though.

11. The speaker of claim 3, wherein the lighting apparatus comprises a cover, at an inner side of which the lighting module is mounted and which is configured to cover a hollow portion of the light diffusion portion.

12. The speaker of claim 1, wherein the light emitting device is disposed at a virtual axial line passing through the center of the vibration portion.

13. The speaker of claim 3, wherein the lighting apparatus further comprises a refraction member provided at an inside the light diffusion portion, the refraction member having a center thereof which protrudes while having a curved surface so as to diffuse light generated from the lighting module toward the vibration portion.

14. The speaker of claim 13, wherein:

the lighting module is provided at an upper end of the light diffusion portion; and

the refraction member is disposed at a lower end of the light diffusion portion while having the protrusion portion disposed in a same direction as a light radiating direction of the lighting module, the refraction member comprising material providing light reflection.

15. The speaker of claim 13, wherein:

the lighting module is provided at an upper end of the light diffusion portion; and

the refraction member covers the lighting module while having the protrusion provided in a same direction as a light radiating direction of the lighting module, the refraction member including material allowing light to pass and reflect there through.

16. The speaker of claim 13, wherein the lighting module is provided at a lower end of the lighting diffusion portion;

and

the refraction member is disposed at an upper end of the light diffusion portion while having the protrusion disposed in an opposite direction to a light radiating direction of the lighting module, the refraction member comprising material providing light reflection.

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

a magnetic circuit part forming a magnetic circuit which comprises a magnet, an upper plate provided at an upper side of the magnet, a lower plate provided at a lower side of the magnet and a pole piece disposed in a center of the magnet; and

a vibration meter configured to generate vibration in the vibration portion by interacting with the magnetic circuit part, the vibration meter having a voice coil provided between the magnet and the pole piece and a bobbin on which the voice coil is installed.

18. A speaker comprising:
