Piezo Buzzer 27mm

Description

• Size: The “27mm” measurement refers to the diameter of the piezo buzzer, indicating its physical dimensions. This size is relatively standard for piezo buzzers and can vary slightly among different models.
• Piezoelectric Effect: Piezo buzzers produce sound by utilizing the piezoelectric effect, which involves the deformation of a piezoelectric crystal when an electric field is applied, creating vibrations that produce sound.
• Sound Generation: These buzzers are typically used to generate audible alert sounds, beeps, or tones. They are commonly found in various electronic devices, appliances, alarms, and timers.
• Operating Voltage: Piezo buzzers generally operate at low voltage levels, typically in the range of a few volts (e.g., 3V, 5V, or 12V). The specific voltage requirement depends on the model and manufacturer.
• Sound Output: The sound output of a piezo buzzer is usually characterized by its sound frequency, volume, and tone. You can find piezo buzzers with different sound characteristics to suit various applications.
• Mounting: Piezo buzzers often come with mounting holes or clips for secure installation in electronic devices or equipment.
• Applications: These buzzers are widely used in applications that require audible signals, including doorbells, timers, alarms, and notification systems. They can also be found in various consumer electronics.
• Simple and Reliable: Piezo buzzers are known for their simplicity, reliability, and low power consumption, making them suitable for a range of applications.
• Continuous or Pulsed Sound: Depending on the model, piezo buzzers can produce either continuous or pulsed sound signals.
• Tone Variation: Some piezo buzzers have a fixed tone, while others allow you to vary the tone by changing the frequency or duty cycle of the input signal.
• Waterproof Varieties: Waterproof or sealed piezo buzzers are available for applications where moisture resistance is required.
