Shenghui Electronic

Product Advantages

1. Compact and Space-Saving Design:

   • The small physical dimensions (14mm diameter x 7mm height) make it ideal for applications where PCB space is limited.

2. Low Power Consumption:

   • As a passive (non-oscillating) component, it requires very little current to drive, making it highly efficient and suitable for battery-powered devices.

3. High Sound Pressure Level (SPL):

   • With an output of 85dB (at a standard distance, e.g., 10cm), it produces a loud and clear tone that can be easily heard even in moderately noisy environments.

4. Simple Drive Circuitry:

   • It can be driven directly by a microcontroller's (MCU) GPIO pin with a simple transistor amplifier circuit, reducing design complexity and component count compared to an active buzzer with a built-in oscillator.

5. Cost-Effective:

   • Passive buzzers are generally less expensive than active buzzers, offering a budget-friendly solution for adding audio feedback.

6. Flexibility in Sound Generation:

   • Since it requires an external oscillating signal (in this case, optimized for 4kHz), it can produce not just a single tone but also sirens, chimes, and simple multi-tone alerts by changing the frequency of the input signal from the MCU.

7. Reliable and Long-Lasting:

   • Piezo elements have no moving parts other than the ceramic disk itself, resulting in high reliability and a very long operational lifespan.
