Pack of 6 piezo buzzer speakers designed for replacement and DIY electronics projects. Each unit functions as a simple piezo alarm or beeper suitable for motherboards, control panels, hand buzzers, and small electric devices. Key benefits Ready to use in repairs and projects: six identical piezo elements provide spare parts or multipoint alerts without extra sourcing. Clear audible alerts: piezo technology produces distinct tones that are easy to hear for status signals and warnings. Easy to integrate: twopin terminals and compact footprint allow soldering or connector mounting on PCBs, motherboards, and prototype boards. Versatile compatibility: works with common lowvoltage boards, microcontrollers, alarm modules, timers, toys, and other electronic circuits. Compact and durable: lightweight construction with a piezo ceramic disc in a protective housing for longterm use. Function and performance Purpose: converts electrical pulses into audible tones for alarms, beeps, and signal notifications. Operation: suitable for pulse, square wave, or continuous drive signals from typical controller outputs or alarm circuits. Efficiency: designed for low to moderate power operation commonly used in electronics projects and system indicators. Sound characteristics: produces a clear, attentiongetting frequency appropriate for alerts and simple audio feedback. Compatibility and mounting Compatible with: PC motherboards that accept external speakers or beepers, Arduino and Raspberry Pi projects, alarm and security circuits, timers, toys, and handheld buzzers. Mounting: compact form factor fits onto PCBs or into small housings; can be soldered or connected with simple twopin connectors. Electrical connection: use appropriate drive voltage and current according to your system requirements; safe for common lowvoltage electronic applications. Materials and size Construction: piezo ceramic element housed in a plastic casing with two external leads for electrical connection. Size: compact footprint suitable for tight spaces on PCBs and enclosures; sold as a set of six identical units. Practical use scenarios Motherboard or system speaker replacement: restore basic beep codes and POST signals by swapping in a piezo beeper when the original speaker fails. DIY alarm and timer projects: add audible alerts to home automation sensors, doorbells, countdown timers, or kitchen timers using a microcontroller or simple oscillator circuit. Toys and educational kits: integrate into hobby electronics, school projects, and handheld buzzers to provide clear audio feedback and simple melodies. What you receive Six piezo buzzer speakers compatible with a wide range of electronic projects and replacement needs, supplied as identical units for consistency across applications. Technical note Verify drive voltage and current requirements for your particular application before connection to prevent damage and ensure expected sound output.
