1. A set of musically interactive coasters for protecting a substrate from engagement with a beverage container, comprising:
a first coaster comprising a body portion, a top support surface and a bottom base surface, said first coaster having a power supply and an activation mechanism, said first coaster further including a first audio player comprising a first memory component for storing a first preprogrammed sound having a first identification code associated therewith, a first speaker for emitting said first preprogrammed sound, and a first circuit for connecting said first speaker to said first memory component, said first coaster further including a first sensor and a first wireless communication interface including a first receiver and a first transmitter for emitting a signal including said first identification code; a second coaster comprising a body portion, a top support surface and a bottom base surface, said second coaster having a power supply and an activation mechanism, said second coaster further including a second audio player comprising a second memory component for storing a second preprogrammed sound having a second identification code associated therewith, a second speaker for emitting said second preprogrammed sound, and a second circuit for connecting said second speaker to said second memory component, said second coaster further including a second sensor and a second wireless communication interface including a second receiver and a second transmitter for emitting a signal including said second identification code; and whereby said first coaster and said second coaster are configured to interact such that when said first speaker emits a preprogrammed sound identified by said first identification code and emits a signal including the first identification code via the first wireless communication interface first transmitter, said second coaster receives said first identification code via said second wireless communication interface second receiver and said second coaster emits said second preprogrammed sound via said second speaker, whereby the sound from the first coaster and the sound from the second coaster are played in musical harmony with one another, and wherein the second sensor senses the audible stimuli emitted by the first speaker and adjusts the second preprogrammed sound to be in musical harmony with the first preprogrammed sound. |
