Industry Background: Demands for High‑sound‑output Piezo Buzzer
Many industrial appliances, alarm devices and household equipment require piezoelectric buzzers with loud sound output and reliable structural design. Poor‑quality buzzers on the market often suffer from low decibel output, loose housing and unstable performance under long‑time working. Selecting buzzer products with high sound pressure and robust plastic housing can greatly improve the user warning experience of terminal products. This white 36mm piezoelectric buzzer is a mature standard product from Guangdong SWT. It features high sound output, snap‑in mounting structure and stable electrical performance, suitable for many industrial and home appliance projects.

Core Electrical and Acoustic Specifications
This white 36mm piezoelectric buzzer has resonant frequency of 2.5±0.2KHz, rated peak‑to‑peak voltage of 12Vp‑p, operating voltage range from 1‑30V(Vp‑p). The maximum current consumption is 8mA. Under test condition of 12Vp‑p, 1/2 duty square wave at 2.5KHz, the minimum sound output reaches 98dB measured at 10cm distance, delivering loud and clear alarm tone. Capacitance tested at 120Hz is 36±30%nF. All indicators are verified under standard test environment: temperature 25±1℃, humidity 45%‑75%, air pressure 86‑106kPa.
Structural Features & Environmental Performance
The buzzer adopts high‑strength PBT white plastic housing, outer dimension φ36±0.5mm, product weight 6.7g. It is designed with snap‑in clip structure for easy buckle installation without extra screws. For environmental adaptability, operating temperature ranges from ‑20℃ to +70℃, storage temperature ranges from ‑30℃ to +80℃. Complete lead‑free soldering parameters for reflow soldering, wave soldering and manual soldering are provided in specification for customer assembly. The sturdy housing structure improves vibration resistance for industrial‑grade usage scenarios.
Wide Application & Procurement Support
This white 36mm piezoelectric buzzer fits for industrial alarm units, large household appliances, security alarm equipment, control panels and other products requiring high‑volume audible alert. It supports small‑batch sample testing as well as large‑volume bulk purchase. With sufficient production capacity, strict quality control and factory‑direct price, this buzzer is a reliable choice for global electronic buyers.
