US Patent 9424827 Electronic percussion instrument with enhanced playing area

Electronic percussion instruments with enhanced playing areas and methods and systems for generating electrical signals in response to impacts to a playing surface are disclosed. A semi-permeable playing surface covering an acoustic noise reducing cavity of an electronic percussion instrument may receive an impact within a predefined impact region, and an electrical signal may be generated in response by an electromechanical sensor that senses the impact. In many instances, the generated electrical signal may be configured to be equivalent in magnitude to any other electrical signal generated by the electromechanical sensor, in response to any other received impact within the same predefined impact region.
