■ Dimension Drawing
A 12mm passive piezo buzzer is a crucial component in various electronic devices. Understanding its pinout is essential for proper integration and functionality.
One of the key aspects related to the 12mm passive piezo buzzer is its compact size. This small form factor makes it suitable for use in space-constrained applications such as portable electronics and small IoT devices. The piezo buzzer operates based on the piezoelectric effect. When an electrical signal is applied to it, the piezoelectric material within the buzzer vibrates, producing sound.
The pinout of the 12mm passive piezo buzzer typically consists of two pins. One pin is for the positive connection, often labeled as +, and the other is for the negative connection, usually labeled as -. These connections are vital for supplying the appropriate electrical signals to the buzzer. For instance, in a simple circuit, the positive pin may be connected to the output of a microcontroller or an oscillator circuit.
In terms of applications, the 12mm passive piezo buzzer finds use in alarm systems. It can emit a distinct sound to alert users in case of a security breach or an emergency situation. Another application is in consumer electronics like mobile phones and tablets. It can be used for notification sounds, such as incoming call alerts or system notifications. Additionally, in industrial control systems, it can provide audible feedback when certain processes are completed or when an error occurs.
The frequency response of the 12mm passive piezo buzzer is also an important factor. Different buzzers may have different frequency ranges, which can be adjusted depending on the requirements of the application. Some buzzers may be optimized for high-frequency sounds, while others may be better suited for lower-frequency tones. This flexibility in frequency response allows designers to choose the most appropriate buzzer for their specific needs.
Why Choose Our Piezo Buzzer
Piezo buzzers has been more and more popularily used as there is no magnetic field and no coil inside. Typically, piezo buzzers consume less current (less than 30mA), have a broader frequency range (2-6kHz) and wider operating voltage (3- 250V), and generate a higher SPL.
Kailitech piezo buzzers include types of taping, SMD, ultra-low frequency, high SPL, waterproof, high temperature and pressure resistant, with diameter or length and width fm 9.0mm to 100mm, height fm 1.8mm to 65mm, with resonant frequency range fm 200Hz to 15kHz and SPL range fm 65dB to 120dB. Housing material can be ABS, PBT, PPO, LCP, etc.
