Modulated resonator generating a simulated flame
View Patent ↗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, and
the mist changes shape and size as a function of the modulation signal;
a light source configured to illuminate the mist.
2. The apparatus as specified in claim 1 wherein the illuminated mist appears as a simulated flame.
3. The apparatus as specified in claim 1 wherein the modulation signal comprises different waveforms such that the mist has an irregular shape, size, and/or height.
4. The apparatus as specified in claim 1 wherein the modulation signal comprises varying power levels such that the mist has an irregular shape, size and/or height as a function of the varying power levels.
5. The apparatus as specified in claim 1 wherein the transducer is configured to cause the dispensed liquid droplets to splash.
6. The apparatus as specified in claim 5 wherein the transducer has at least one opening configured to pass the mist.
7. The apparatus as specified in claim 1 wherein the dispenser is configured to dispense the liquid droplets to have varying sizes to form a varying vapor plume.
8. The apparatus as specified in claim 1 further comprising a shaping member configured to pass and shape the mist.
9. The apparatus as specified in claim 8 wherein the shaping member is comprised of a cone or other shape.
10. The apparatus as specified in claim 1 wherein the light source is configured to illuminate the mist from within the mist.
11. The apparatus as specified in claim 10 wherein the light source is colored.
12. The apparatus as specified in claim 7 wherein the modulation signal comprises varying power levels such that the mist has an irregular shape, size and/or height as a function of the varying lower levels.
13. The apparatus as specified in claim 12 further comprising a shaping member configured to pass and shape the mist.
14. The apparatus as specified in claim 1 further comprising a reservoir configured to hold a liquid, and the dispenser s configured to dispense the liquid from the reservoir as the liquid droplets.
15. The apparatus as specified in claim 12 wherein the dispenser is configured to dispense the liquid droplets at a variable rate.
16. The apparatus as specified in claim 10 wherein the dispenser comprises a conduit encompassed by the light source.

20. An apparatus, comprising:
a transducer;
a dispenser configured to dispense liquid droplets on to the transducer;
a control circuit configured to generate a modulation signal, the modulation signal configured to drive the transducer such that:
the liquid droplets proximate the transducer transduce to a vapor plume, and
the vapor plume changes shape as a function of the modulation signal; and
a light source configured to illuminate the vapor plume such that the vapor plume appears as a simulated flame.
21. The apparatus as specified in claim 20 wherein the modulation signal comprises different waveforms such that the vapor plume has an irregular shape.
22. The apparatus as specified in claim 20 wherein the modulation signal comprises varying power levels such that the vapor plume has an irregular shape.
23. The apparatus as specified in claim 20 further comprising a shaping member configured to pass and shape the vapor plume.
