  • Patent number: 4817485
    Abstract: A pedal operated electronic drum. The electronic drum includes a pedal pivotally coupled to a base and a first striking or anvil element mounted on the base. A second striking or hammer element is operably coupled to the pedal so that depression of the pedal causes the hammer element to strike the anvil element. A transducer is acoustically coupled to the anvil element to convert impact induced vibrations in the anvil element into an electrical output signal. In one embodiment the hammer element is attached to a roller pivotally coupled to the base. A strap is wrapped about the roller and attached to the base so that depression of the pedal rotates the axle thereby causing the hammer element to strike the anvil element. In an alternative embodiment the strap is coupled to the pedal instead. Both of these embodiments may be adjusted to simulate the "feel" of a conventional pedal operated drum striking element.
