Abstract: The key actuation system is designed for use with a keyboard instrument of the type having multiple keys. Each of the keys has an upper and lower surface and is pivotally supported above a key bed. A front end of a key may be depressed by a player to play a note. The key bed extends under and is spaced from the lower surface of the key. The actuation system includes an underlever in the space between the lower surface of the key and the key bed, and between the front end of the key in the pivotal support. The underlever has one end that is supported in a stationary position relative to the key bed and another end that is movable towards and away from the key bed. The movable end of the underlever is in mechanical communication with the key such that movement of the movable end of the underlever towards the key bed causes the key to move as if depressed by a player. An actuator is in mechanical communication with the underlever and operable to move the second end of the underlever towards the key bed.

Abstract translation: 钥匙致动系统设计用于具有多个键的键盘乐器。 每个键具有上表面和下表面，并且枢转地支撑在键床上方。 钥匙的前端可能被玩家压下来播放音符。 钥匙床在键的下表面下方延伸并与钥匙的下表面隔开。 致动系统包括在钥匙的下表面和钥匙床之间的空间中以及在枢转支撑件中的钥匙的前端之间的底部。 底部有一端支撑在相对于钥匙床的固定位置，另一端可向着和远离钥匙床移动。 底部的可移动端与钥匙机械地连通，使得底部的可移动端朝向钥匙床的移动使得钥匙像玩家按压一样移动。 致动器与底部机械连接，并且可操作以使底部的第二端朝向键床移动。
