DC Mechanical Vibrating Buzzer 6V Active Sound & Tactile Module 2315

Specifications

• Model: 2315 Mechanical Vibrating Buzzer
• Operating Voltage: 6V DC
• Operating Current: 30mA 
• Feedback Mechanism: Acoustic (Continuous Tone) + Tactile (Mechanical Vibration)
• Dimensions (Diameter × Height): 23mm × 15mm 
• Terminal Type: PCB Mountable Pins
• Operating Temperature Range: -10°C to +60°C 
• Compatible Platforms: Direct DC power, or driven via Arduino/ESP32 using a relay or transistor
• Sound Output Type: Continuous mechanical buzz

Minimum hardware to get started:

• Arduino Uno or ESP32 development board : to trigger the alert sequence based on your code logic.
• 5V Relay Module or NPN Transistor (e.g., 2N2222) : to safely switch the mechanical buzzer's power. The module's internal motor draws more current than a microcontroller pin can safely provide.
• 6V DC Power Supply or 4x AA Battery Pack : to deliver the optimal voltage required for maximum acoustic and vibrating resonance.
• Jumper Wires (Male-to-Male) : to connect the power supply, driver module, and microcontroller.

Safety Warnings:

• Current Draw Warning: Do NOT connect this buzzer directly to a digital GPIO pin on your Arduino, ESP32, or Raspberry Pi. The mechanical vibration mechanism draws high peak currents that can permanently fry your microcontroller's logic pins. Always use a relay or transistor to switch it.
• Inductive Load Warning: Because this module contains a mechanical coil/motor, it generates voltage spikes when turned off. If you are building a custom transistor driver circuit, ensure you include a flyback diode.

Frequently Asked Questions(FAQs)

• Is the 2315 mechanical buzzer compatible with Arduino Uno?
  Yes, it is fully compatible with Arduino Uno, provided you use a relay or transistor to switch the 6V power.
• Does this module work with 3.3V boards like ESP32 or Raspberry Pi?
  Yes, you can trigger it using a 3.3V logic signal, but the buzzer itself must be powered by a separate 6V supply via a relay or transistor.
• Can I connect multiple 2315 buzzers to the same microcontroller?
  Yes, you can control multiple units on separate pins, but ensure your external power supply has enough current capacity for simultaneous activation.
• Is this buzzer suitable for outdoor enclosures?
  It can be used inside outdoor enclosures, but the module itself is not waterproof and should be protected from direct moisture.
• What is the optimal operating voltage for this buzzer?
  The module is rated for 6V DC to achieve maximum acoustic resonance and mechanical vibration.
• Will this buzzer operate on a standard 5V USB power supply?
  Yes, it will operate at 5V, though both the volume and the tactile vibration strength will be slightly reduced.
• How much current does the mechanical buzzer draw?
  It typically draws around 30mA during continuous operation, but requires a higher peak current to initiate the mechanical movement.
• Can I connect this directly to an Arduino digital pin?
  No, the mechanical coil draws too much peak current and will permanently damage standard microcontroller GPIO pins.
• Does polarity matter when wiring this buzzer?
  Yes, it is a DC-powered mechanical device, so you must connect the positive and negative terminals correctly.
• Do I need a flyback diode in my circuit?
  Yes, if you are building a custom transistor driver, you must include a flyback diode (like a 1N4007) to protect against inductive voltage spikes.
• Can I use the tone() function to play melodies on this buzzer?
  No, this is an active mechanical buzzer with a fixed frequency and cannot generate variable musical notes.
• Can I control the vibration strength using PWM?
  Yes, sending a PWM signal via analogWrite() can reduce the effective voltage, allowing you to lower the vibration intensity and volume.
• Which Arduino library is required to run this module?
  No special library is needed; a simple digitalWrite(pin, HIGH) is all it takes to activate the buzzer.
