SPEAKER INCLUDING SPEAKER APPARATUS AND LIGHTING APPARATUS Russian patent published in 2018 - IPC H04R9/02 

FIELD: lighting.

SUBSTANCE: invention relates to acoustics, in particular to speakers provided with a lighting module. Speaker comprises a magnetic circuit, a frame, a coil, a diffuser, a lower plate mounted on the underside of the magnet and a pole piece located at the centre of the magnet. Coil is located in the gap between the magnet and the pole piece. Device also comprises an edge located between the end portion of the vibrating part and the frame, and a spider centering washer. Vibrating part includes a material capable of reflecting light without scattering the light. Light intensity, degree of scattering, movement of light and light colour are controlled in accordance with the strength and weakness of the acoustic signal. Lighting device is located at the centre of the diaphragm, fixed to the top of the pole piece and comprises light scattering. Lighting module comprises a printed circuit board and LEDs, which enable to emit homogeneous light onto the vibrating part. Light scattering unit is in the form of a prism whose outer surface is curved. In particular, the light scattering unit is in the form of a column having a hollow portion and a concave-convex portion formed on its outer surface. Concave-convex part is formed from a transparent material.

EFFECT: technical results are improving the efficiency of lighting, providing visual effects.
