    [0006]
    6. SPEAKER, according to claim 5, characterized in that the concave/convex part (122) comprises a ventilation hole (124), provided on the inner side of the concave/convex part (122) to radiate the heat generated by the light emitting device (112).
    [0007]
    7. SPEAKER, according to claim 4, characterized in that: convex part (122a) is formed protrudingly; and the concave part (122b) is recessed, as compared to the convex part (122a), while being formed adjacent to the convex part (122b)), where one of the convex part (122a) and the concave part (122b) is opaque, and the remaining part is transparent.
    [0008]
    8. SPEAKER, according to claim 1, characterized in that the lighting device (100) also comprises: support part (130), configured to have a lower part of the light diffusion part (120) mounted on it, the support part (130) configured to be mounted and fixed in the center of the vibration part (42).
    [0009]
    9. SPEAKER, according to claim 7, characterized in that the support part includes heat-resistant material.
    [0010]
    10. SPEAKER, according to claim 7, characterized in that the support part comprises a support tube (134) having a cable hole (134a), allowing a cable (114) to transmit electrical signals to the device light emitter (112) passes through it.
    [0011]
    11. SPEAKER, according to claim 1, characterized in that the lighting device (100) comprises a cover, on whose inner side the lighting module (110) is mounted, and which is configured to cover the part diffuser (120) having a hollow part.
    [0012]
    12. SPEAKER, according to claim 1, characterized in that the light-emitting device (112) is arranged on a virtual axial line passing through the center of the vibrating part.
