Embodiment Construction

[0022] Such as figure 1 As shown, the acousto-optic conversion device of the present invention is driven in an analog manner, so the output signal has real time. The present invention includes a plurality of audio intensity identifiers 10 , a plurality of light source drivers 12 and a plurality of light emitting elements 14 , and the light emitting elements 14 are light emitting diodes as examples. The above-mentioned audio intensity recognizer 10 receives a sound source signal, and each audio intensity recognizer 10 recognizes an audio signal of different frequencies and different volume intensities from the sound source signal, and outputs it. Each light source driver 12 is directly connected to each audio intensity recognizer 10 to receive a corresponding audio signal and convert it into an electrical signal. Each light emitting element 14 is respectively connected to each light source driver 12 and receives a corresponding electrical signal to generate a corresponding lig...

Abstract

The invention discloses an acousto-optical conversion device and a conversion method thereof. The conversion device includes a plurality of audio-intensity identifiers for receiving a sound-source signal. The audio-intensity identifiers all identify audio-frequency signals with different frequencies and volume intensities from the sound-source signal and then outputting the audio-frequency signals. The audio-intensity identifiers are each connected directly with a light-source driver respectively and the light-source drivers are for receiving corresponding audio-frequency signals and converting the audio-frequency signals into electric signals. The light-source drivers are each connected with a light-emitting element used for receiving corresponding electric signals so that corresponding light signals are generated respectively. Through the method, an acousto-optical stereo effect is achieved and people feel as if personally on the scene.

Description

technical field [0001] The invention relates to a conversion technology, in particular to an acousto-optic conversion device and a conversion method thereof. Background technique [0002] Since the commercialization of light-emitting diodes in the 1960s, due to their high shock resistance, long life, low power consumption, and low heat generation, their application range covers various items in daily life, such as home appliances and various instruments. lights or light sources etc. In recent years, due to the development of multi-color and high-brightness, the scope of application is more developed towards outdoor displays, such as large outdoor display signs and traffic lights. Red, blue and green are the three primary colors of full-color. For full-color outdoor display boards, high-brightness blue or green LEDs are indispensable. [0003] In the prior art, light-emitting diode (LED) lighting systems are usually used in large plazas, advertising billboards or any applic...
