In every field of digital electronics, most of engineers are looking for small sound devices such as buzzer, micro speaker. This trend encouraged Bosan to develop a small magnetic buzzer as seen in picture right in 2003.

This, 5 mm buzzer, is so small that it can be placed in a clip. So this one can substitute huge components such as piezo buzzer, micro speaker for simple sounds like key-pad tones. And simple program, simple structure of circuit.

With 5 mm buzzer, engineers can develop slim-and-small portable digital products with smart sound, and actually engineers of iPod MP3 player from Apple computer knew this and applied this component since 2003.

Now, don't lose your time with piezo buzzer, micro speaker to solder them manually. Don't suffer to squeeze PCB space with huge components. Do not worry that this might sound little. This little giant usually can buzz more than 84 dB @ 10cm.

And of course, all products in this website are Pb-free.
