提出了一种提取声音幅度或节拍间隔信号用来实时控制发光环旋转速度的驱动技术和方法,通过语音拾取、检波、低通滤波器和开关网络的设计实现对由多段RGB LED发光体构成的发光环旋转速度的有效自动控制,达到声光同步互动的效果,为园林亮化建设、智慧家居和舞台灯光增添了新的元素。
A driving technique and method for extracting the sound amplitude or beat interval signal for real-time control of the rotation speed of the light emitting ring is proposed. The design of a multi-segment RGB LED light emitter is achieved through design of speech pickup, detection, low pass filter and switch network, Luminous ring rotation speed of the effective automatic control, to achieve the effect of sound and light synchronized interaction for the garden lighting construction, smart home and stage lighting adds a new element.
