Currently, small hand-held products are a commonplace in our life. As we can see, these products are getting smaller and smaller, so that the small audio devices come necessary.

The parts provide a typical sound output of 80dBA at 10cm though the parts may be small. It is comparable to parts three times the size. There are three versions of different configurations to select, which make a great option for small-held devices.

The SMT 0540 series Transducers, electro-mechanical devices, use a permanent magnet surrounding an electro-magnetic coil with a very thin metal diaphragm resting on top in construction.

When power (0-p signal) is adopted, the electro-magnetic coil will pulse moving the diaphragm up and down very fast. Varying the input signal voltage and/or frequency will make the sound output change. The device will have the loudest sound output with an input signal set to the resonant frequency at the maximum rated voltage. The parts can be manufactured with different resonant frequencies by changing the coil and/or modifying the sound chamber.

There are three version options provided from PUI.
