Customer Reviews
David K., Electronics Designer: "The 1KHz tone from this Shenghui buzzer is perfect for our consumer timer product. The 5V drive compatibility made the design straightforward, and the consistency across our order was excellent."
Procurement, Small Appliance Maker: "We needed a reliable, cost-effective passive piezo buzzer for our product line. This 5Vp-p model from Shenghui Electronic has provided consistent performance and simplified our sourcing with all necessary certifications like CCC and CE."
Lisa W., R&D Engineer: "Great service from this passive piezo buzzer manufacturer in China. The samples performed exactly as per the 80dB spec, and the team was responsive to our volume production questions. A reliable partner for standard components."
Q1: What is the main advantage of a 1KHz frequency in a buzzer?
A1: A 1KHz frequency produces a clear, mid-range tone that is easily audible to the human ear and effective for general-purpose alerts. It often offers a good balance between perceptibility and power consumption compared to higher frequencies.
Q2: Can I drive this 5v passive buzzer directly from a microcontroller GPIO pin?
A2: Yes, it is designed for this purpose. You can drive it by outputting a 1KHz square wave signal from a microcontroller pin. Ensure the pin can source/sink sufficient current (check the buzzer's data sheet for current consumption) and that the voltage swing is close to 5V peak-to-peak for optimal sound output.
Q3: Does Shenghui offer variants with different sound pressure levels or mounting styles?
A3: Absolutely. As an experienced passive piezo buzzer factory, Changzhou Shenghui Electronic offers a wide range of customization options. We can adjust the sound pressure level, frequency, operating voltage, and pin configuration (e.g., wire leads, SMD mounting) to meet your specific design requirements.
