扬声器
摘要：
一种扬声器，其包括：玻璃基材，振荡器，该振荡器相互间隔地设置在该玻璃上；LED光条，该LED光条上间隔设置有多个LED光源，该LED光源正对该第一表面设置；LED准直器，其设置在LED的出光光路上，其用于对LED光源发出的发散光线进行准直并且将准直光束耦合进入该玻璃；光栅，其设置在玻璃上与LED光条的位置对应处，其用于将到达第一表面的光束绕射进入该玻璃基材；及控制单元，该控制单元用于控制振荡器的振动及用于控制LED光源的发光亮度随音频信号进行变化。
摘要（英）：

The invention provides a loudspeaker, which comprises a glass substrate, oscillators arranged at intervals on the glass substrate, an LED light strip provided with a plurality of LED light sources arranged at intervals thereon, an LED collimator arranged on the LED bright dipping path and used for collimating the diverging light of the LED light sources and then coupling the collimated light to the glass substrate, an optical grating arranged on the glass substrate and positioned corresponding to the LED light strip, and a control unit. The LED light sources are arranged to be right facing a first surface. The light that reaches the first surface is diffracted by the optical grating to enter the glass substrate. The control unit is used for controlling the oscillation of the oscillators and controlling the light-emitting brightness of the LED light sources to vary along with audio signals.
