the GJ-5020 passive electromagnetic buzzer is a small audio component commonly used in electronic circuits to produce alert sounds or simple tones.
Electromagnetic buzzers operate by using an internal coil and magnet. When the driving signal is applied, it causes a small diaphragm within the buzzer to vibrate, producing sound. With a compact 5mm size, these buzzers are ideal for space-constrained applications, such as compact consumer electronics, small household gadgets, or portable devices. SMD design simplifies the assembly process in automated production, making it a popular choice for mass-manufactured devices.
The GJ-502SMD buzzers operate at low voltage levels (around 2.5V to 5V) and offer a modest sound pressure level, which is sufficient for close-range notifications They are energy-efficient, which contributes to the longevity of battery-operated devices. Commonly, they are used in applications where size and low power consumption are prioritized over volume
