Abstract
One example embodiment provides a lighting device. The lighting device includes a lighting component, at least one coil, and a driving circuit. The lighting component connects with a movable magnet to project light on a flame sheet from different positions. The coil is disposed adjacent to the movable magnet to apply a magnetic force to move the movable magnet in response to a driving current in the coil. The driving circuit connects with the coil and the lighting component to provide the driving current according to a characteristic parameter of an electronic signal converted from an audio signal. The characteristic parameter includes one or more of an amplitude, a frequency and an envelope of the electronic signal. The lighting component moves with a speed and a direction controlled by the audio signal.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
