Mini Speaker - PC Mount 12mm 2.048kHz

Questo è un piccolo dispositivo acustico di 12 millimetri, rotondo, che opera in tutta la gamma a 2kHz udibile. Deve essere alimentato con 5V e puo essere utilizzato per creare musica semplice o interfacce utente.

This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces. This is not a true piezoelectric speaker but behaves similarly. Instead of a piezoelectric crystal that vibrates with an electric current this tiny speaker uses an electromagnet to drive a thin metal sheet. That means you need to use some form of alternating current to get sound. The good news is that this speaker is tuned to respond best with a square wave (e.g. from a microcontroller).
