Abstract:
1. A method for detecting a location of a percussion stroke impinging on an electronic percussion device having a drumhead and a rim, wherein the percussion stroke is received on the drumhead or on the rim, and generating in response a corresponding percussion sound signal, the method comprising: providing a peripheral carrier, configured to allow motion having at least one degree of freedom, for receiving vibrations from a plurality of locations on the drumhead; providing an electrical signal in response to vibrations received from the peripheral carrier, the electrical signal having an equilibrium level at which no vibrations are detected; determining whether the percussion stroke impinges on the drumhead or on the rim by one of (i) examining the received electrical signal at an initial moment of reception of the stroke, and in case the signal is rising above the equilibrium level, determining that the stroke was induced on the drumhead, and (ii) examining the received electrical signal at the initial moment of reception of the stroke, and in case the signal is falling below the equilibrium level, determining that the stroke was induced on the rim; and generating a corresponding percussion sound signal in response to reception of the percussion stroke on the drumhead or on the rim.
