    • Techniques described herein generally include methods and systems related to a MEMS-based audio speaker system configured for generating an audio signal. The speaker system includes one or more apertures in the speaker system positioned to receive the ultrasonic carrier signal and one or more movable and over-sized obstruction elements that are configured to modulate the ultrasonic carrier signal and thereby generate an audio signal. Because the movable obstruction elements are configured to overlap one or more edges of the apertures when in the closed position, modulation depth of the generated audio signal can be substantially improved or otherwise varied.
    • 这里描述的技术通常包括与被配置用于生成音频信号的基于MEMS的音频扬声器系统有关的方法和系统。 扬声器系统包括位于扬声器系统中的一个或多个孔,其定位成接收超声波载波信号,以及一个或多个可移动和超大尺寸的阻碍元件,其被配置为调制超声波载波信号并由此产生音频信号。 因为可移动障碍物元件被配置为在处于闭合位置时与孔的一个或多个边缘重叠,所以所产生的音频信号的调制深度可以被显着改善或以其他方式改变。
