Product Advantages

This buzzer is designed for applications where a low-profile, easy-to-drive component is required for clear audio feedback. Its specifications offer distinct advantages:

1. Ultra-Low Profile Design

• The minimal height of 4.0mm is a significant advantage for modern, slim-line consumer electronics and compact PCBs where vertical space is extremely constrained.

2. Simplified Direct Microcontroller Drive

• The low 5V peak-to-peak (Vp-p) drive voltage requirement means it can often be driven directly from a 5V microcontroller's GPIO pin (through a current-limiting resistor) or with a very simple, low-cost transistor circuit. This simplifies design and reduces the Bill of Materials (BOM) cost.

3. Space-Efficient Diameter

• The 17.0mm diameter provides a larger sound-producing surface area compared to smaller buzzers (e.g., 12mm), contributing to a clearer and more efficient sound output without being overly large.

4. Optimal Frequency for Alert Tones

• The 4kHz resonant frequency is within the range where the human ear is most sensitive, ensuring the 80dB tone is perceived as clearly audible and attention-grabbing, ideal for alerts and notifications.

5. Cost and Power Efficiency

• As a passive component, it consumes less power than an electromagnetic buzzer and is typically more cost-effective than an active buzzer with a built-in driver, offering excellent value.

6. High Reliability

• Piezo buzzers have no moving coils to wear out, making them highly reliable and resistant to shock and vibration, ensuring a long operational lifespan.

Applications

This buzzer is perfect for any device that requires a clear, piercing alert tone. Common applications include:

• Household Appliances: Microwave ovens, washing machines, rice cookers, air conditioners (end-of-cycle alerts, button press confirmation).

• Consumer Electronics: Digital multimeters, thermostats, smoke/CO detectors, security system keypads.

• Automotive Electronics: Keyless entry systems, tire pressure monitoring system (TPMS) sensors, reverse parking sensors.

• Industrial Controls & Equipment: Alarm panels, timers, counters, machinery status indicators (e.g., error beeps).

• Electronic Toys and Gadgets: Audio feedback for button presses or game events.
