The present disclosure provides a system and method of using a window as a microphone keyboard input. Systems and methods for using a window as a microphone instead of keyless entry into a vehicle are disclosed. The system includes a window that uses a piezoelectric transducer as a microphone that captures resonance on an outer surface of a vehicle window when a pressure wave (e.g., a voice command or strike) impacts the vehicle window. To recognize this sound, a transducer controller amplifies vibrations from a window strike or spoken command. The system may include a low power mode that listens for input when the vehicle is off. In the second high power mode, the system may detect a tap event that may cause a transition to a wake-up state. The system may associate the number of taps and time with a unique user key, similar to numeric key selection on a keyboard. The system may also identify a verbal PIN code input using the piezoelectric transducer microphone.
本公开提供了“将窗户作为传声器键盘输入的系统和方法”。公开了使用窗户作为传声器来替代无钥匙进入车辆的系统和方法。所述系统包括窗户,所述窗户使用压电换能器充当传声器,当压力波(例如语音命令或敲击)冲击车辆窗户时,所述压电换能器捕获所述车辆窗户的外表面上的共振。为了识别这种声音,换能器控制器放大来自窗户敲击或口说命令的振动。所述系统可以包括在所述车辆关闭时监听输入的低功率模式。在第二高功率模式下,所述系统可以检测可以促使转变到唤醒状态的敲击事件。所述系统可以将敲击的次数和时间与独特的用户密钥相关联,类似于键盘上的数字键选择。所述系统还可以使用所述压电换能器传声器识别口头PIN码输入。
