20pcs Copper Piezo Disc Sensor Set Sensitivity Piezoelectric Pickup for Guitar Drum DIY Projects

20 Piece Copper Piezo Discs Acoustic Sound Sensors for Instruments Description A pack of 20 copperbacked piezoelectric discs designed as responsive acoustic sound sensors and buzzers for musical instruments and electronics. These compact transducers convert vibration into electrical signals with sensitivity, making them suitable for instrument pickups, drum triggers, contact microphones, and DIY sensing projects. Easy to install and reliable in repeated use. Key benefits Improved pickup of vibration and impact: Converts mechanical vibrations into usable electrical signals for amplification, triggering, or recording. Ready for projects and repairs: Pack of 20 provides spares for multiple instruments or prototypes, reducing downtime. Simple installation: Compact discs fit common mounting methods and are suitable for quick retrofits or builds. Durable construction: Copper backing and piezoelectric ceramic element deliver consistent responsiveness across applications. Versatile compatibility: Works with drums, guitars, percussion, contact mics, buzzer circuits, and microcontroller sensor inputs. Features and attributes Function: Piezoelectric transducer for converting vibration to voltage; can act as pickup, sensor, or buzzer element. Material: Copper backing with piezoelectric ceramic active element for stable electrical output. Form factor: Thin, discshaped sensors sized for easy installation on instrument surfaces and enclosures. Performance: sensitivity and fast response suitable for transient sounds and rhythmic triggers. Quantity: 20 pieces per pack for multiple installations or replacements. Recommended use scenarios Drum trigger: Mount a disc on a drum shell to detect strikes and feed the signal to an electronic drum module or trigger interface. Guitar or acoustic pickup: Attach under the bridge or inside the body as a contact pickup for amplified acoustic performance or recording. DIY sensing and microcontroller projects: Use as a vibration sensor or contact microphone to detect knocks, taps, or mechanical events in interactive builds. Practical notes These are passive sensors. For results, pair with a impedance input or a simple preamp to match signal levels to amplifiers, recording gear, or microcontroller analog inputs. Placement and mounting affect sensitivity and tonal balance. Small adjustments in location and mounting method can optimize response for each instrument or application. The pack of 20 provides convenience for experimentation, multiple instruments, or spare replacements. This set is intended for instrument electronics, audio projects, and general vibration sensing where compact, responsive piezo transducers are needed.
