An SMD Piezo Buzzer uses the piezoelectric effect to generate sound. When voltage is applied to the piezoelectric material, it vibrates and produces an audible tone. These are ideal for compact PCB-mounted applications.
A magnetic buzzer operates using a coil and a magnet. When current flows through the coil, it creates a magnetic field that moves a diaphragm, producing sound. SMD magnetic buzzers are efficient and widely used in consumer electronics.
Self-drive buzzers have an internal oscillator and only require DC voltage to operate. External-drive buzzers need an external signal to generate sound, offering more control over frequency and tone.
Yes, we offer waterproof speakers and buzzers designed for outdoor or high-moisture environments. These are ideal for automotive, marine, and industrial applications.
Yes, we provide OEM/ODM services. Our engineering team can customize voltage, sound level, size, and mounting style based on your requirements.
