  • Universal trigger module
    Patent number: 10121462
    Abstract: Described is a trigger module that can be used with percussive instruments to generate an electric signal. The trigger module includes an enclosure with a strike plate. A piezoelectric transducer is affixed with the bottom of the strike plate. A striker having a protrusion is attached with the enclosure such that the protrusion rests proximate the strike plate. Thus, forcing the striker towards the strike plate causes the protrusion to impact the strike plate, thereby causing the piezoelectric transducer to generate an electric signal.
