Patent ID: 7634411

Claim:
A system for generating synchronized effects in a model train having a selected moving component, comprising: a. at least one sensor located on said model train for sensing the position of said selected moving component and generating a synchronized signal corresponding to said position of said selected moving component; b. memory means located on said model train for storing train sounds; c. a processor located on said model train for retrieving said train sounds from said memory means and playing them in synchronization with said synchronized signal to create a synchronized train sound signal; d. a radio transmitter located on said model train for transmitting said synchronized train sound signal; e. a sound generator located separately from said model train, wherein said sound generator includes, i. a receiver for receiving said synchronized train sound signal from said model train, ii. a first speaker for projecting said synchronized train sound signal; f. a second speaker located on board said model train; g. a filtering system for separating said synchronized train sound signal into a first component containing higher frequencies and a second component containing lower frequencies; h. wherein said first component is played over said speaker located on board said model train; and i. wherein said second component is played over said first speaker.
