Sound recording and reproduction system for model train using integrated digital command control
First Claim
1. A sound reproducing system for a model train traveling on a plurality of rails that uses a amplified digital control signal for propulsion and control, the system comprising:
- a sound memory storing a plurality of sound effects at predetermined addresses;
a controller connected to the sound memory for recalling the sound effects of either one or a plurality of sound effects in a predetermined sequence or a random sequence;
a sound memory containing multiple samples that emulate a model locomotive at various speeds and work loads;
an integrated sound, motor and special effects controller controlled by a bi-polar digital signal, the motor and special effects controller re-producing the stored sounds contained in the model train; and
a digital packet triggering a sound effect for automatic playback of a sound effect.

Abstract
A system is provided for recording, storing and reproducing sound for playing back in an environment requiring simulated sounds, voices, and/or sound effects. Sounds are recorded on a chip and played back in an asynchronous manner from the chip as a result of activation of a switch or inertial movement within the system. A Hall-effect sensor, reed switch or momentary switch or the like may be implemented for enabling activation of the recorded sound from the chip for broadcasting. A compander compresses the sound on the chip and expands the compressed sound for playback. Employing the above system for audio storage, a sound, motor and special effects controller may be created for model train applications as well. The different functions of the sound unit are controlled through a discrete bi-polar digital command control signal using a unique address for each unit. A synchronous means of play back may also be employed when the system is used with the bi-polar signal using a sensor. In addition to the analog sound storage, the same concepts and ideas may be applied to a digital sound recording and play back device as well.

21. A sound reproducing system for a model train traveling on a plurality of rails that uses an amplified digital control signal for propulsion and control, the system comprising:
-
a sound unit;
a memory within the sound unit wherein the memory stores a plurality of sound effects at addresses wherein the sound effects contain multiple samples that emulate a train locomotive at various speeds and various work-loads wherein the memory has an analog wave form representing sound effects of a locomotive at the various speeds and the various work-loads or a digital representation of the analog wave form that represents a plurality of sound effects of a locomotive at the various speeds and the various work-loads wherein the sound effects simulate the various speeds and the various work-loads by comparing the on-off rate of a sensor to a digital speed packet; and
a controller connected to the memory for recalling at least one of the sound effects wherein the controller is controlled by a digital signal. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
