Abstract
A triggering apparatus for triggering an acoustic drum synthesizer includes (a) a body attachable to the frame of an acoustic drum to transmit acoustic vibrations from the drum frame or shell, the body configured to pass a drum receiver rod, (b) dual transducer structures carried by the body to be responsive to the transmitted vibrations, to produce signals, (c) and circuitry connected to the dual transducer structures to process the signals, passing only a selected high frequency band of such signals to the synthesizer, to trigger same.
Claims12
In a triggering means for triggering an acoustic drum synthesizer, the combination comprising:
- (a) a body having attachment means thereon for firmly attaching the body to the frame of an acoustic drum so as to transmit acoustic vibrations from the frame, the body configured to pass a drum receiver rod,
- (b) dual transducer means carried by the body to be responsive to the transmitted vibrations to produce corresponding signals,
- (c) and circuit means connected to the dual transducer means to process said signals, passing only a selected high frequency band of such signals to the synthesizer to trigger same,
- (d) and including said acoustic drum frame to which said body is attached, externally of the frame, and a drum tensioner rod carrier by the frame and passing through the body,
- (e) the body comprising a block of material within which said dual transducer means is concealed and contained, and means clamping the body against the frame, to receive acoustic vibrations therefrom, and to pass said tensioner rod, there being support means integral with the body, the dual transducer means carried in position to receive transmission of acoustic vibrations from the block, via said support means.
