Buzzer(Passive Buzzer)
₦200.00
A passive buzzer is an audio signaling device that produces sound through an external oscillating signal. Unlike an active buzzer, which generates sound with an internal oscillator, a passive buzzer requires an external signal to produce sound. This type of buzzer is commonly used in various electronic projects and devices for alarms, notifications, and sound effects.
Key Features:
- Requires external oscillating signal for sound generation
- Produces a wide range of frequencies (depending on the input signal)
- Compact and lightweight design
- Easy to integrate into electronic circuits
- Low power consumption
Technical Specifications:
- Type: Passive Buzzer
- Operating Voltage: Typically 3V to 12V (varies by product)
- Frequency Range: 1kHz to 10kHz (depends on external signal)
- Sound Pressure Level: Typically 85dB at 10cm (varies by product)
- Current Consumption: Typically 10mA to 30mA (depends on voltage and signal)
- Dimensions: Varies by product (commonly around 12mm diameter, 8mm height)
- Operating Temperature Range: -20°C to +70°C (varies by product)
- Mounting Type: Through-hole or surface mount
Applications:
- Alarm and notification systems
- Timers and clocks
- Electronic toys and games
- Sound effects in various devices
- Prototyping and DIY projects
Usage:
- Connect the passive buzzer to your microcontroller or signal generator circuit.
- Provide an oscillating signal (square wave) to the buzzer’s input pin to generate sound. The frequency of the signal determines the pitch of the sound.
- Adjust the signal frequency and duty cycle to achieve the desired sound output.
- Ensure the power supply voltage is within the specified operating range to avoid damage to the buzzer.
Caution:
- Ensure the input signal frequency is within the buzzer’s specified range to avoid distortion or damage.
- Verify the power supply voltage to prevent overvoltage conditions.
- Handle the buzzer carefully to avoid damage to the delicate internal components.
