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.
Claims20
An electronic percussion instrument, comprising:
- an element defining a surface;
- and
- a layer of ferrous responsive material disposed on the surface.
A method of forming a drumhead, comprising:
- providing a membrane defining a first surface and an opposite second surface;
- and
- printing a graphic on one or both of the first surface and second surface of the membrane, wherein
- the graphic is printed with ferrous responsive ink.
1 more element
An electronic drumming assembly, comprising:
- a drumhead having a membrane having ferrous responsive material integrated into the membrane;
- an electromagnetic sensor element positioned spaced from the ferrous responsive material and configured to sense vibrations of the membrane;
- and
- a communication pathway communicatively connecting the electromagnetic sensor element to a sound module configured to generate an acoustic sound in response to an input signal from the electromagnetic sensor element, wherein when the membrane is struck, the electromagnetic sensor element senses movement of the membrane and sends a signal to the sound module which thereby generates an acoustic sound associated with the drumhead.
