The magnetic buzzers (Self-drive Type) offer optimal
sound and performance for all types of audible alert and identification. Our
Magnetic Buzzer solutions are offered with various mounting options. We also
provide you with a washable version for your preferred soldering method. Our magnetic buzzers, also known
as indicators, are designed with an internal drive circuit for easy application
integration. During operation, current is driven through a voice coil to
produce a magnetic field. When a voltage is applied, the coil generates a
magnetic field and then allows the diaphragm to vibrate and produce sound. This
Buzzer type has a low operating voltage ranging from 1.5 – 12V+. Our magnetic
buzzers are desirable for applications requiring a lower sound pressure level
(SPL) and frequency.
