Electronic Drum Second-Rim Sensing for Side-Stick Accuracy

The drum kit is segmented into multiple independent detection zones: head sensor for head hits, first rim sensor for first rim hits, and second rim sensor for second rim hits. Each sensor independently detects vibrations from its specific location, allowing simultaneous operation of multiple playing methods without interference. The segmentation of detection responsibilities resolves the contradiction by enabling versatility through multiple hit positions while maintaining precision through dedicated sensors for each position.

Each sensor is optimized for its specific detection location: the head sensor is tuned to detect head vibrations, the first rim sensor for first rim vibrations, and the second rim sensor for second rim vibrations. By assigning specialized detection characteristics to each sensor based on its location, the system achieves high sensitivity for detecting intended hits while maintaining reliability by having dedicated sensors that can distinguish their specific hit patterns from vibrations caused by hand contact on other components.

The system performs preliminary detection and identification of hand contact vibrations on the head before they can interfere with second rim hit detection. By detecting these preliminary vibrations and identifying them as non-hit events, the system can prepare to distinguish subsequent second rim hits from the ongoing head vibrations, maintaining detection accuracy despite the presence of hand-induced vibrations.
