Piezo ceramic wafer plate and disc assembly for pickup, trigger, and buzzer applications Overview This piezo ceramic wafer plate and piezo disc with leads is a versatile sensor and transducer for musical instruments, DIY electronics, and replacement buzzer applications. As a piezo microphone and drum disc with wire, it converts mechanical vibration into an electrical signal and, when driven with an alternating voltage, produces mechanical movement. The included leads make installation simple for a wide range of projects. Key benefits Dual function sensing and actuation: converts impact or vibration into a voltage signal for pickup or sensing, and produces mechanical vibration when driven electrically for buzzer or transducer use. Easy integration: comes with preattached leads/wire for fast connection to amplifiers, preamps, microcontrollers, or simple circuits. Broad compatibility: suitable as an accessory for drums, practice pads, acoustic guitars, and other instruments, and for DIY projects such as touch sensors, box sensors, and trigger buzzers. Simple replacement: use as a direct substitute for worn or broken piezo buzzers and contact microphones. Compact and robust construction: thin piezo ceramic wafer plate form factor designed for mounting under drum heads or inside enclosures without adding bulk. Features and attributes Function: piezoelectric transducer that both senses mechanical force and acts as a small vibrator when driven. Material: piezo ceramic wafer plate construction for reliable electromechanical response. Electrical connection: piezo discs with leads included for soldering or quick wiring. Form factor: flat circular wafer suitable for surface mounting, adhesive attachment, or placement in cavities. Performance: responsive to impact and touch, with good sensitivity for contact microphone and trigger applications. Typical applications Drum pickup: mount under a drum head or on a practice pad to capture hits for amplification or trigger conversion to electronic signals. Instrument pickup: attach to an acoustic guitar or other stringed instrument as a contact microphone or replacement piezo pickup. DIY electronics and sensors: use as a touch sensor, box tamper sensor, trigger for buzzers, or input transducer for microcontroller projects. Installation tips Secure the wafer plate with adhesive or doublesided tape at the desired contact point to maximize vibration transfer. Connect the leads to a impedance input or suitable preamplifier when using as a microphone to preserve signal quality. If using as a buzzer or actuator, drive with an appropriate alternating signal and ensure the mechanical mounting allows visible or audible movement. Compatibility note Designed to work with common pickup and sensor setups for drums, guitars, and DIY electronic projects. The simple twolead connection allows integration with amplifiers, effects, trigger modules, and microcontroller circuits. This piezo ceramic wafer plate and disc assembly offers a practical, easytoinstall solution for sensing and soundproducing tasks in musical and electronic projects without requiring complex hardware changes.
