This 6Vp-p 4KHz 85dB Passive Piezo Buzzer is a high-performance, cost-effective audible signaling component designed for clear and reliable alerts. Operating on a 6V peak-to-peak voltage at a precise 4KHz frequency, it delivers a consistent 85dB sound output. This passive piezo buzzer requires an external driving circuit (typically a square wave) to generate sound, offering engineers greater control over tone patterns. It is an ideal solution for applications requiring a compact, efficient, and durable audible alarm. Optimized for performance, this 4KHz buzzer is a reliable choice for consumer electronics, automotive alerts, and industrial equipment.

Q1: What is the difference between a passive and an active buzzer?
A1: An active buzzer has an internal oscillator and sounds with a DC voltage. This product is a passive piezo buzzer, requiring an external driving circuit (like a 4KHz square wave) to produce sound, offering flexibility in tone control.
Q2: What driving circuit do I need for this 6Vp-p passive buzzer?
A2: You need to provide a square wave signal at its resonant frequency (around 4KHz) with a 6V peak-to-peak voltage. A simple oscillator circuit from a microcontroller pin is commonly used.
Q3: Can Shenghui customize the frequency, sound pressure, or pin configuration?
A3: Yes, as a professional passive piezo buzzer manufacturer, Changzhou Shenghui Electronic offers customization services. We can adjust parameters like frequency, dB level, pin type, and housing to meet your specific application requirements. Contact us with your specs.
