Frequently Asked Questions (FAQ)

Q1: Why is the frequency 4.1KHz instead of a more common value like 4.0KHz?

A: The 4.1KHz frequency is a finely tuned resonant point for this specific SMD Piezo Buzzer design, optimized to deliver the best combination of sound clarity, efficiency, and component longevity. Driving it at this frequency ensures the rated 72dB output is achieved reliably, making it an effective piezo alarm buzzer.

Q2: How do I properly drive this passive 5v piezo buzzer from a 3.3V microcontroller?

A: This is a Passive Piezo Buzzer and requires an external drive circuit. It cannot be connected directly to a microcontroller pin. You will need a simple driver circuit using a transistor. The 3.3V GPIO pin can control an NPN transistor or an N-channel MOSFET. The transistor then switches a 5V power source to drive the buzzer with the required 5Vp-p signal. This allows the SMD Piezo Buzzer to produce its full sound output.

Q3: Can the sound pressure level or operating voltage of this piezo alarm buzzer be customized for our product?

A: Yes, absolutely. Customization is a core service at Shenghui Electronic. As the direct manufacturer, we can adjust parameters such as the resonant frequency, sound pressure level, operating voltage (e.g., 3Vp-p, 12Vp-p), and dimensions of this 5v piezo buzzer platform to meet your specific requirements.
