10mm Piezoelectric Ceramic Buzzer

10mm Piezoelectric Ceramic Buzzer with soldered wire offers a compact and highly efficient solution for adding audible feedback to any electronic project or device. Unlike magnetic buzzers, this tiny component uses the piezoelectric effect, producing a high-pitched, clear tone by converting an electrical signal into mechanical vibration. Since it’s a passive buzzer, you control the pitch and duration of the sound directly from your microcontroller, allowing for complex melodies, alarms, and confirmation tones. With its small 10mm diameter and pre-soldered 5cm wires, this buzzer is ready for immediate integration into space-constrained designs, making it perfect for wearables, small toys, and portable monitoring equipment.

Key Features:

• Highly Compact Form Factor: The 10mm diameter allows for seamless integration into miniature devices and space-constrained PCB designs.
• Passive Design: Requires an external oscillating signal (typically a PWM signal from a microcontroller) to generate a tone, giving you complete control over frequency and pitch.
• Low Power Consumption: Piezoelectric technology draws minimal current, making it highly suitable for battery-operated and energy-efficient systems.
• Clear, High-Frequency Tone: Produces a distinct, noticeable sound for effective alerting and signaling.
• Ready-to-Use Wires: Includes pre-soldered, flexible 5cm wires for direct connection to breadboards or circuit terminals, significantly speeding up prototyping.

Technical Specifications:

• Type: Passive Piezoelectric Buzzer
• Operating Voltage: 3 V to 20 V Peak-to-Peak (V_P-P)
• Rated Voltage: ≈ 12 V_P-P
• Operating Frequency Range: 2.0 kHz to 4.0 kHz
• Sound Pressure Level (SPL): ≥ 85 dB (at 10 cm, 12 V_P-P)
• Maximum Current Draw: ≈ 15 mA (Typically much lower)

Mechanical Specifications:

• Housing: Typically ABS Plastic (Black or other color)
• Connection: Two soldered wires (Red/Black or similar color code)
• Mounting: Designed for adhesive mounting or securing within an enclosure.

Dimensions:

• Diameter: 10 mm
• Height/Thickness: ≈ 3.0 mm to 5.0 mm
• Wire Length: ≈ 5 cm
• Weight: ≈ 1 g

Pinout and Wiring:

• Red Wire (Positive): Connect this wire to the digital I/O pin on your microcontroller (e.g., Arduino, ESP32) that outputs the PWM signal.
• Black Wire (Negative): Connect this wire to the GND (Ground) pin on your power source and microcontroller.
• Usage Note: Since the current draw is low, you can often connect the positive wire directly to the microcontroller pin, but for longer usage or higher voltages, consider using a transistor (like an NPN) to drive the buzzer and protect the microcontroller.

Commonly Used in:

• Prototyping Boards: Essential for Arduino and Raspberry Pi projects needing sound alerts.
• Digital Clocks and Timers: Providing end-of-cycle alerts.
• Miniature Electronic Toys: Generating sound effects and musical output.

Applications:

• Simple Alarms and Alerts: Signaling faults, low battery warnings, or motion detection.
• Interactive Sound Effects: Providing feedback for button presses or input validation.
• Musical Playback: Generating simple melodies by varying the output frequency.

Equivalent Models:

• Active Buzzer Modules: These contain an internal oscillator and only require a DC voltage, offering less control over pitch.
• Larger Piezo Buzzers (e.g., 20mm): Produce higher sound pressure levels (louder volume) but require more mounting space.
• Electromagnetic Speakers: Offer high-fidelity audio output but are generally larger and more complex to drive.

Package Includes:

• 1 x 10mm Piezoelectric Ceramic Buzzer with 5cm Soldered Wire
