一种钢琴键盘手感精准调节装置
本技术属于钢琴调节装置
,具体涉及一种钢琴键盘手感精准调节装置。
技术介绍
传统钢琴在实现钢琴向上复位的过程中,由于通过弹簧弹性进行复位,弹奏者在按下琴键或者琴键回弹的时候容易感到手感生硬,影响弹奏的感觉;另外,弹簧的弹性不能进行适时调整,因此难以方便不同的弹奏者准确调节琴键的力度,此外,弹簧在长时间使用以后弹性会发生变化,使得琴键力度也发生变化。申请号为CN201220294772.7的技术专利公开了一种立式钢琴键盘手感调节装置,其包括琴架、配重块、琴键和琴键支柱,琴键支柱固定在琴架上,其上端与琴键中间位置铰接,琴键的按键端位于琴键支柱一侧,琴键的配重端位于琴键支柱的另一侧,所述琴键的配重端设有导轨,配重块和导轨滑动连接。利用琴键支柱固定在琴架上,其上端与琴键中间位置铰接,琴键的按键端位于琴键支柱一侧,琴键的配重端位于琴键支柱的另一侧,所述琴键的配重端设有导轨,配重块和导轨滑动连接,整个装置构成一个杠杆结构,配重块在导轨上可滑动,实现了配重块的力矩可调整,进而实现琴键力度大小的方便、准确调整,使弹奏者在弹钢琴时的手感好。该专利虽然通过配重块的滑动可以很好的调节琴键的力度,但其配重块需要在配重块的球面凸起结构到达导轨的凹孔时才实现配重块位置的固定,而凹孔之间的间距难以进行把控,对于不同的弹奏者,同一钢琴上琴键的配重块难以调节到最佳位置,因此该专利难以做到精确调节的程度,导致整体的调节效果较差;另一方面,因为配重块置于琴键的下方,多个琴键进行安装在钢琴上时,配重块的位置便难以进行很好的调整,导致整体使用不方便,难以很好调节 ...
