Disclosed is a touch input device that determines touch position by sensing vibrations propagating in a touch plate that are indicative of a touch to the touch plate. Vibration sensing devices such as piezoelectric sensors are used to sense the vibrations. Selecting the size, shape, placement position and orientation of the sensors on the touch plate can enhance sensitivity of the sensors to vibration and yield symmetric response with respect to the direction of vibration propagation. Also disclosed is a method of making a vibration sensing touch input device.
(ZH) 公开了一种接触式输入装置，该装置通过感测在接触面板内传播的振动而确定接触位置，该振动表示施加在接触板上的接触。振动敏感器件比如压电传感器用来感测这些振动。选择接触板上的传感器的大小、形状、放置位置以及定向，能够提高传感器对振动的灵敏度并且产生相对于振动传播方向对称的响应。还公开了制造振动敏感接触式输入装置的方法。
