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:
- a drumhead membrane stretched across a substantially circular hoop and defining a surface with a circumference;
- and
- a layer of ferrous responsive material permanently cured to the surface about the circumference thereof in a ring-like pattern, wherein
- the ferrous responsive material is non-magnetic.
A method of forming a drumhead, comprising:
- providing a membrane defining a first surface and an opposite second surface;
- applying a graphic on one or both of the first surface and second surface of the membrane with a curable ferrous responsive material;
- and
- exposing one or both of the first surface and second surface of the membrane to conditions to cure the ferrous responsive material to the one or both of the first surface and second surface, wherein
- the ferrous responsive material is non-magnetic.
An electronic drumming assembly, comprising:
- a drumhead having
- a membrane stretched across a substantially circular hoop and defining a top surface and bottom surface;
- and
- a layer of ferrous responsive material permanently cured to one or both of the top surface and bottom surface of the membrane, the layer forming a substantially ring-like pattern coaxial to the drumhead;
- an electromagnetic sensor element positioned spaced from the ferrous responsive material and configured to sense vibrations of the membrane via the ferrous responsive material;
- 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, and
- the layer of ferrous responsive material is non-magnetic.
