Modulated Resonator Generating a Simulated Flame

摘要

An apparatus having a transducer configured to be modulated and transduce a liquid and form a simulated flame. The transducer may be piezoelectric transducer driven by a modulated drive signal that has varying power levels such that a liquid transduces to a mist, and also such that the transducer controls and shapes the mist to create a vapor plume. The plume is illuminated by a colored light source generating the simulated flame. A wick or a nozzle may present the liquid to the transducer. The wick may have different shapes i.e. helical, tiered, and include intertwined or braided fiber optic cables of varying colors, or LED lights/tubes. The transducer may have multiple openings, perforations, notches, and/or impressions to shape the plume and creating the effect of a dancing flame.

1. An apparatus, comprising:
a transducer having a surface, a dispenser configured to dispense liquid droplets to impinge upon the transducer surface; a control circuit configured to generate a modulation signal, wherein the modulation signal is configured to drive the transducer such that:
the liquid droplets convert to a mist, andthe mist changes shape and size as a function of the modulation signal; a light source configured to illuminate the mist.
