摘要:
An electronic drum, comprising: a bottom member; a drum head; a drum sensor comprising: a passive resonant circuit mounted on the drum head and having a resonant frequency; and an active resonant circuit mounted on the bottom member and configured to excite the passive resonant circuit at the resonant frequency; a sensor driver to drive the active resonant circuit with an RF drive signal at the resonant frequency; and a detector to detect a level of RF signal from the driven active resonant circuit for sensing a position and/or velocity of the drum head; and a signal processor, coupled to the detector, configured to process the detected level of RF signal to sense a position and/or velocity of the drum head for determining when the drum head is hit.
