Abstract
Trigger devices, systems, and methods for sensing a strike on a vibratory membrane. A trigger device includes an optical sensor positioned a distance from the vibratory membrane and a processing device. The optical sensor includes an emitter that emits modulated light towards the vibratory membrane and a receiver that receives the modulated light that has reflected off the vibratory membrane and generates an electrical signal corresponding to the received modulated light. The electrical signal includes a peak corresponding to a detected strike on the vibratory membrane. The processing device isolates the peak from the electrical signal and generates one or more of a signal and data corresponding to the electrical signal.
