Abstract:
A drumhead includes a membrane with ferrous responsive material printed onto a surface or otherwise incorporated into it. The ferrous responsive material is detectable by an electromagnetic sensor such that striking the membrane causes vibration that is detected by the sensor, which may initiate an acoustic sound via a sound module. The drumhead may thus be used in an electronic drumming system without requiring fixation of a foreign object to a surface of the membrane.
