A surface-mount magnetic buzzer with an integrated drive circuit, producing sound when powered by a DC voltage. It shares the same form factor and performance as the SMD magnetic transducer but requires no external signal generation. With a frequency range of 2–5 kHz, 75–90 dB SPL, and low power consumption, it is well-suited for compact, automated designs in smart wearables, IoT devices, and consumer electronics.
