Short Product Description

Looking for a reliable, unmistakable audio alert for your next electronics project? Our 6V Mini Mechanical Buzzer delivers a clear, consistent 75dB sound at a low-pitch 400Hz frequency. Perfect for DIY alarms, custom timers, and STEM learning kits, it features a durable ABS casing and pre-soldered wire leads for immediate integration. Stop struggling with quiet, easily missed signals—ensure your project's alerts are always heard loud and clear.

Key Features

  • Clear 75dB Audio Output: Delivers a loud, unmistakable alert that cuts through moderate background noise without causing discomfort.
  • Standard 6V DC Operation: Effortlessly powers up using common battery packs or standard DC power supplies, simplifying your circuit design.
  • Pre-soldered 9cm Wire Leads: Saves you valuable assembly time and allows for immediate, frustration-free connections to your project.
  • Compact ABS Enclosure: Provides excellent structural durability and heat resistance (-20°C to +60°C) while maintaining a minimal footprint on your board.
  • Convenient 3mm Mounting Holes: Allows for secure, permanent installation onto cases, panels, or custom 3D-printed enclosures using standard screws.

Full Product Description

Dependable Audio Alerts for Every Electronic Project

Whether you are prototyping a home security system on a breadboard or building a classic Morse code transmitter, reliable audio feedback is crucial.

Many standard buzzers on the market either lack the volume to be heard in a busy room or require complex circuitry to operate. This 6V Mechanical Buzzer solves that problem by offering a plug-and-play solution that guarantees a robust 75dB output the moment power is applied.

 

Why Choose a Mechanical Buzzer?

Unlike high-pitched piezoelectric buzzers that can sound shrill, a mechanical buzzer generates sound through physical vibration. This creates a distinct, lower-frequency (400Hz) "buzz" that is highly noticeable but less grating on the ears. It is the perfect balance of volume and tone for indoor applications, control panels, and user interfaces.

 

Seamless Integration for Makers and Engineers

We know that time spent stripping and tinning tiny wires is time taken away from building your actual project.

That is why this buzzer comes equipped with pre-soldered 9cm red and black wire leads, allowing for instant connection to standard breadboards, screw terminals, or PCB through-holes. Furthermore, the base features dual 3mm mounting holes, making it incredibly easy to securely fasten the component to your project's chassis.

FAQ Section

Q. Can I use this buzzer with microcontrollers like Arduino or Raspberry Pi?
A. Yes, but because mechanical buzzers can draw higher current than standard I/O pins can provide, it is recommended to use a simple transistor circuit to drive the buzzer safely from your microcontroller.

Q. Does this buzzer require an external oscillator or PWM signal?
A. No. This is an active mechanical buzzer. Simply apply standard 6V DC power across the red (positive) and black (negative) leads, and it will continuously generate its 400Hz tone.

Q. Is this buzzer waterproof?
A.No, the ABS casing features open vents to release the sound. It is designed for indoor use or within a weather-resistant enclosure if used outdoors.
