The present disclosure provides a system and method for piezoelectric sensor microphone window keyboard input. Systems and methods for using a window as a keyboard input system that functions as an alternative to a keyless entry keyboard in a vehicle are disclosed. The system includes a window that uses a piezoelectric transducer as a keyboard that captures resonance from the window when a pressure wave (e.g., generated by a voice command or tap) impacts the glass. The transducer controller amplifies vibrations from a window user tap or verbal command and triangulates the signal to locate the location of the start point of the tap, which may be mapped to a corresponding digital or cardinal input value. The system may include a low power mode that receives an input when the vehicle is off.
本公开提供了“用于压电传感器传声器车窗键盘输入的系统和方法”。公开了使用车窗作为键盘输入系统的系统和方法,所述键盘输入系统用作车辆中的无钥匙进入键盘的替代。所述系统包括使用压电换能器用作键盘的车窗,所述压电换能器在压力波(例如,由语音命令或轻击生成的)撞击玻璃时捕获来自车窗的谐振。换能器控制器放大来自车窗用户轻击或口头命令的振动,并对信号进行三角测量以定位轻击的起始点的位置,所述位置可以被映射到相应的数字或基数输入值。所述系统可以包括在车辆关闭时接收输入的低功率模式。
