Magnetic Passive Buzzer Suppliers

An electromagnetic passive buzzer, also known as an electromagnetic transducer, is a type of buzzer that generates sound using an electromagnetic mechanism. It is a variation of the passive buzzer.

Here are some key characteristics of an electromagnetic passive buzzer:

    Construction: An electromagnetic passive buzzer consists of a coil, a diaphragm, and a magnet. The coil is wound around a central core, and the diaphragm is attached to the core. The magnet is positioned near the coil.

    Operation: When an alternating current (AC) signal is applied to the coil, it generates a changing magnetic field. This changing magnetic field interacts with the magnet and causes the coil and diaphragm to vibrate rapidly.

    Sound Generation: The rapid vibration of the diaphragm produces sound waves, resulting in audible sound. The frequency of the sound is determined by the frequency of the applied AC signal.

    External Signal Source: An electromagnetic passive buzzer requires an external AC signal source, such as a microcontroller or a signal generator, to generate the appropriate frequency and control the sound output.

    Voltage Requirement: It typically operates at a low voltage, often around 5V or 12V, depending on the specific model and application.

    Sound Output: An magnetic passive buzzer generally produces a single tone or a simple sound, without the ability to generate complex melodies or multiple tones.

    Control Complexity: As with other passive buzzers, controlling the frequency and duration of the sound is handled by the external signal source, which provides the AC signal.

Electromagnetic passive buzzers are commonly used in various applications, including alarms, timers, and electronic devices that require audible alerts or notifications. Their simple construction and ease of integration make them popular components in many electronic systems.
