Abstract: A portable electronic drumhead sensor which converts impact forces exerted by a drumstick or hand into electrical pulses input to headphones to thereby simulate sounds of an acoustic drumhead includes a Force Sensing Resistor (FSR) lamination coated with an electrically conductive polymer ink, a spacer lamination, and a flexible electrode lamination having on an inner surface thereof interdigitated electrodes, the electrode lamination elastically contacting the FSR lamination in response to impact forces on the outer surface of either lamination to momentarily reduce electrical resistance between the electrodes. An annular ring-shaped embodiment of the sensor positionable on an acoustic drumhead has an upwardly protruding resilient bumper strikable to produce electronically synthesized rim-shot sounds.

Abstract: A portable electronic drumhead includes a sensor responsive to drumstick impacts in producing electrical signal pulses input to headphones to thereby simulate sounds of an acoustic drumhead. The sensor includes a Force Sensing Resistor (FSR) lamination coated with an electrically conductive polymer ink, a spacer lamination, and a flexible electrode lamination having on an inner surface thereof a pair of interdigitated electrodes, the electrode lamination elastically contacting the FSR lamination in response to drumstick impacts on the outer surface of the electrode lamination or FSR lamination to thus momentarily reduce electrical resistance between the electrodes. Resilient batter pads overlying the laminations muffle sounds produced by drumstick impacts. Optionally, the sensor may have an annular ring shape which may be placed concentrically on the head of an acoustic drum, the sensor having an upwardly protruding resilient bumper strikable to produce electronically synthesized rim shot sounds.

Abstract: A unique mounting device for a cymbal providing a quick-release arrangement. The mounting device, adapted to be secured to the free end of a cymbal stand, includes a bushing mount that is positioned on and secured to the stand, the bushing mount being adapted to receive a flexible cymbal restraint, wherein a keeper member is formed as an integral part thereof to allow the cymbal to be snapped on and off. Mounted to the restraint below the keeper member is a cymbal-support bracket having a felt pad, whereby the cymbal is held in position between the keeper member and the pad to provide positive angular positioning of the attached cymbal, and yet allow the spring to geniculate when necessary.
