- When the drum pad is struck, the stick initially compresses the playing surface of the pad, causing the material (usually rubber, mesh, or silicone) to deform and store energy.
- The deformed material then rapidly springs back, propelling the stick upwards and generating a rebound.
2. Vibration of the pad:
- The impact of the stick sets the entire drum pad into vibration, causing it to oscillate at its natural resonant frequencies.
- The material of the pad, its size, shape, and construction all affect the frequency and duration of these vibrations, which influence the sound produced.
3. Generation of sound:
- The vibrations of the drum pad cause the air around it to vibrate as well, producing sound waves.
- The shape of the pad and its enclosure, as well as the materials used, affect how these sound waves are projected and amplified.
4. Electronic response:
- If the drum pad is part of an electronic drum kit, the vibrations are detected by sensors mounted beneath the playing surface.
- These sensors convert the mechanical vibrations into electrical signals, which are then processed by the drum module to produce various electronic drum sounds.
5. Audio output:
- The processed electronic drum sound is then sent through an audio system, such as amplifiers and speakers, to produce audible output.
