Abstract:
An electronic percussion apparatus for use with an acoustic drum. The apparatus has a base layer of material having a first side for contacting a drum head of an acoustic drum, and an opposite, second side. The apparatus has a top layer of material joined to the base layer of material. A percussion detector is between the top and base layers. The percussion detector generates electrical signals in response to percussion impacts on the top layer. The top and bottom layers each have a thickness that acoustically isolates the drum head from percussion impacts on the top layer, wherein when the electronic percussion apparatus is placed on a drumhead of an acoustic drum and percussion impacts occur on the top layer, the drumhead is acoustically isolated from the percussion impacts and the percussion detector generates electrical signals in response to the percussion impacts on the top layer.
