摘要： An enhanced bass drum pedal is provided with an eccentricity-adjustable cam system comprising a cam core mounted on a rotating shaft, a cam member rotatably connected to the cam core by a first pin, a positioning member rotatably connected to the cam member by a second pin, and a set screw. The positioning member is fastened onto the cam core by the set screw at a selected position of the positioning member to adjust the eccentricity of the cam system relative to the axis of rotation. As a result, a user can readily alter the impact force acted on a drum head and the restoring force applied to the foot board thereby tuning the bass drum pedal to suit the user's playing style and ability.

摘要： A keyboard instrument such as an electronic piano comprises a keyboard structure that is basically identical to the keyboard structure of an upright piano except hammer assemblies and a struck portion attached to an action bracket. Each of the hammer assemblies is constituted by a hammer shank and a pseudo hammer, one of which is used to strike the struck portion having a multilayer structure including an elastic member (e.g., a plate spring) sandwiched between buffer materials. The elastic member has a prescribed number of striking areas in correspondence with keys arranged on a keybed, wherein the striking areas are gradually increased in weights and bends (or deflections) in a pitch descending order from higher pitches to lower pitches. Thus, it is possible to simulate weight factors and bends (or deflections) of strings actually struck by hammer felts in an upright piano.
摘要翻译：诸如电子钢琴的键盘乐器包括键盘结构，其基本上与直立钢琴的键盘结构相同，除了锤子组件和附接到动作支架的敲击部分。每个锤组件由锤柄和假锤构成，其中一个用于击打具有夹在缓冲材料之间的弹性构件（例如板簧）的多层结构的击打部分。弹性构件具有与布置在键盘上的键相对应的规定数量的打击区域，其中击打区域以从较高间距到较低间距的间距降序逐渐增加重量和弯曲（或偏转）。因此，可以模仿在直立钢琴中实际上被锤子毡击中的弦的重量因子和弯曲（或偏转）。
