The invention includes a vehicle simulator for simulating the sounds and vibrations generated by a moving vehicle. The vehicle simulator includes a housing configured to receive any standard infant carrier including infant vehicle seats. An acoustic system, including an acoustic output transducer and a control unit, is coupled to the housing. The control unit provides a drive signal to the acoustic transducer, which the acoustic output transducer converts into sound waves that provide both vehicle movement sounds and vehicle movement vibrations. When an infant carrier in which an infant is seated is received within the housing, the vehicle movement sounds and vibrations are transmitted by the acoustic output transducer to the infant carrier where the sounds and vibrations create a soothing environment of sound and vibration designed to mimic the environment inside a moving vehicle.

The invention claimed is: 1. An infant carrier base for use with an infant carrier having a lower portion, the base comprising: a substantially rigid housing defining a hollow interior region and having a substantially rigid upper platform with an upper surface configured to removably receive and support the lower portion of the infant carrier; a loudspeaker coupled to the housing inside the hollow interior region and configured to convert a drive signal into sound waves that provide both vehicle movement sounds and vehicle movement vibrations configured to vibrate the substantially rigid housing to thereby simulate vibrations generated by a moving vehicle, the drive signal comprising frequencies from about 28 Hz to about 75 Hz; and a control unit coupled to the housing and configured to generate the drive signal, wherein the control unit is operably connected to the loudspeaker to transmit the drive signal to the loudspeaker. 2. The base of claim 1 wherein the drive signal has an associated drive signal level, the base further comprising an accelerometer coupled to the housing wherein the accelerometer is configured to measure a vibration level and the accelerometer is coupled to the control unit to control the drive signal level based on the vibration level. 3. The base of claim 1, wherein the control unit comprises a memory configured to store a plurality of audio files each convertible by the control unit into the drive signal and the drive signal is selected from the plurality of audio files. 4. The base of claim 3, wherein the control unit comprises a user interface operable by a user to select one of the plurality of audio files. 5. The base of claim 1, wherein the drive signal comprises a duration and the control unit comprises a user interface operable by a user to select the duration of the drive signal. 6. The base of claim 5, wherein the control unit comprises a memory configured to store a plurality of predetermined drive signal durations and the duration of the drive signal is selected from the plurality of predetermined drive signal durations. 7. The base of claim 1, wherein the drive signal comprises a drive signal level and the control unit comprises a user interface operable by a user to select the drive signal level. 8. The base of claim 7, wherein the control unit comprises a memory configured to store a plurality of predetermined drive signal levels and the drive signal level is selected from the plurality of predetermined drive signal levels. 9. The base of claim 1, comprising a remote control configured to send a wireless command signal wherein the control unit is configured to receive and execute the wireless command signal. 10. The base of claim 1, wherein the loudspeaker is coupled to the housing inside the hollow interior region below the substantially rigid upper platform and positioned to direct the sound waves toward the substantially rigid upper platform, the substantially rigid upper platform transferring vehicle movement vibrations provided by the sound waves to the lower portion of the infant carrier. 11. The base of claim 10, wherein the substantially rigid upper platform has a lower surface opposite its upper surface, the lower surface facing the hollow interior region defined by the housing, and the loudspeaker is adjacent the lower surface. 12. The base of claim 1, wherein the sound waves are amplified by the hollow interior region defined by the housing. 13. The base of claim 1 for use with an infant carrier having a lower portion selectively couplable to and detachable from a base portion installable in a vehicle, wherein the upper surface of the substantially rigid upper platform comprises a concave portion configured to removably receive the lower portion of the infant carrier when the lower portion of the infant carrier is detached from the base portion. 14. An infant carrier base for use with an infant carrier, the base comprising: a self-supporting rigid hollow outer shell having a rigid infant carrier support portion configured to removably receive and support the infant carrier a loudspeaker coupled inside the self-supporting hollow outer shell and configured to generate sound waves in response to a drive signal that vibrate the self-supporting hollow outer shell to simulate vibrations generated by a moving vehicle, the drive signal comprising frequencies from about 28 Hz to about 75 Hz, when vibrating, the self-supporting hollow outer shell vibrating the infant carrier supported thereby; and a control unit coupled to the loudspeaker and configured to transmit the drive signal thereto. 15. The base of claim 14 for use with an infant carrier having a convex lower portion, wherein the rigid infant carrier support portion of the self-supporting rigid hollow outer shell has a contoured portion configured to receive and support the convex lower portion of the infant carrier.
