10mm*3mm piezo transducer for telephone ringer with leads
Specification
Product Overview
The MSPT10A32W90V10 10mm×3mm Piezo Transducer with Leads is designed for telephone ringers, compact alert devices, electronic reminders, communication equipment, and small acoustic notification systems. With a compact 10.0×3.2mm size, low current consumption, and 3200±500Hz resonant frequency, it provides a practical sound component for space-limited electronic products.
This piezo transducer provides a minimum sound output of 80dB at 10cm and supports a rated voltage of 10Vp-p. Its operating voltage range of 1–30Vp-p allows flexible circuit design for different ringer, beeper, and alert sound requirements.
The lead-wire design supports convenient installation in telephone ringer circuits and compact electronic assemblies where direct wiring is preferred over pin mounting.

Applications
This 10mm piezo transducer is suitable for telephone ringers, electronic buzzers, compact beepers, communication equipment, warning devices, alarm circuits, portable electronics, small appliances, and embedded sound notification systems.
It is also suitable for OEM and ODM projects where a small piezo sound component with lead wires, low current consumption, and stable ringer frequency is required.
Working Principle
A piezo transducer uses a piezoelectric ceramic element to convert an electrical signal into mechanical vibration. When driven near its resonant frequency, the ceramic element vibrates and produces audible sound.
Because this component is designed as a transducer, the final sound pattern depends on the external drive circuit. Engineers can adjust the frequency, waveform, and pulse pattern to create telephone ringer tones, alert sounds, or reminder beeps.
Design and Integration Notes
For best acoustic performance, drive the transducer near its 3200±500Hz resonant frequency and keep the voltage within the specified 1–30Vp-p operating range.
Sound output may vary depending on drive voltage, waveform, duty cycle, enclosure structure, mounting method, sound outlet design, and measuring distance.
Before mass production, confirm the required sound output, operating voltage, resonant frequency, lead length, installation space, current limit, and temperature range in the final product design.
