Device for generating mist and a model train containing such a device

摘要

A mist generating device and a model locomotive containing such a device are disclosed. The mist generating device comprises: a piezoelectric transducer 1 configured to vibrate a plate and atomise liquid contacting the plate to generate the mist 6; and a signal generator for generating a driving signal for driving the piezoelectric transducer. The signal generator comprises: an input for receiving a signal indicative of a sound made by a steam or diesel locomotive; and circuitry configured to generate a signal synchronised to the received sound signal and to output the signal as the driving signal. The mist generating device may be applied to any model vehicles, buildings, accessories or figures both static and non-static where the exhaust output is required to be synchronised to an audio output.
