US Patent 6632989: Electronic pad with vibration isolation features
US 6632989 · granted 2003-10-14
Abstract
The present invention is intended to provide an electronic cymbal having improved accuracy for detecting a striking force and a striking position without hampering a striking sensation and an appearance. A piezoelectric sensor 5 and a cup portion sheet sensor 8 provided on a portion of a cup portion formed into a dome shape at a center of a cover 2 on a first frame 3 having the cover 2 formed out of a soft material, the cover 2 spreading to contact with an upper surface of the first frame 3, and an edge upper portion sheet sensor 7 and an edge lower portion sheet sensor 6 provided on an outer peripheral edge portion 3b formed to be lowered by a step are provided, and a center of a second frame 4 is supported by a cymbal stand (shaft) 10 penetrating an opening portion at a center of the first frame 3.

Claim 1
An electronic pad receiving a strike, detecting the strike and outputting a signal representative of the strike comprising: a first frame; a striking sensor detecting thestrike transmitted to said first frame; and a second frame supporting said first frame from below, having an attachment hole with a pivotal joint; and a rotation stopper member coupled to the second frame for preventing said first frame fromcircumferentially rotating about a pole of a stand, said pole being inserted into said attachment hole, said attachment hole located in said rotation stopper member, said pivotal joint being rockably fitted into said rotation stopper member withresulting play.
