GLASS LOUDSPEAKER EMITTING SOUND AND ACCOUSTICALLY-DRIVEN LIGHT

摘要

A glass loudspeaker emitting sound and acoustically-driven light includes a glass substrate, a plurality of exciters, a light bar, a plurality of coupling collimators, a diffractive grating, and a control unit. The exciters are arranged at intervals on the glass substrate. The light bar is arranged toward the glass substrate and includes a plurality of light sources. The coupling collimators are arranged on the light-emitting path of the light sources. The diffractive grating is arranged on the glass substrate and toward the light bar. The control unit is electrically connected with the light bar and the exciters, and includes an acoustic signal receiving unit, an audio signal amplifier, an audio signal analyzer, and a current distributor.

1. A glass loudspeaker configured to emit sound and acoustically-driven light, the glass loudspeaker comprising:
a glass substrate comprising a top surface and a bottom surface opposite to the top surface; a plurality of exciters being arranged at spaced apart intervals on the top surface; a light bar being arranged in a direction toward the top surface and comprising a printed circuit board and a plurality of light sources evenly spaced apart on the printed circuit board; a plurality of coupling collimators, each of the plurality of coupling collimators being arranged on a light path of a corresponding one of the plurality of light sources; a diffractive grating being arranged on the top surface and in a direction toward the light bar; and a control unit electrically connected with the light bar and the exciters, the control unit comprising:
an acoustic signal receiving unit configured to receive an acoustic signal from an external source;an audio signal amplifier configured to receive the acoustic signal from the acoustic signal receiving unit;an audio signal analyzer analyze the acoustic signal and obtain an intensity amplitude of the acoustic signal; anda current distributor,wherein the audio signal analyzer is configured to convert the intensity amplitude of the audio signal into current intensity signal and transmit the current intensity signal to the current distributor, which distributes the current intensity signal to each of the plurality of light sources.
