A system for playback of messages. Context appropriate messages for an environment may be played back. Messages may be user behavior interactive and subject to user behavior initiated message playback conditions. User generated environment events may be automatically analyzed and user behavior interactive messages may be automatically coordinated. An automated themed message playback apparatus may have a self-contained housing within which a stored themed message, an in situ user generated environment event sensor, and an automated themed message playback device are housed. User generated environment events may be automatically sensed in situ.

An audio device that is usable at a point of sale location such as a refrigerator or a cabinet having a range of products. The audio device includes a body to be attached to an object that is to be moved by a person, for example the door of the refrigerator, and an electronic circuit mounted on the body. The electronic circuit includes an electrical power source, a speaker, a motion detector and a memory unit. The motion detector causes operation of the unit and speaker upon movement of the detector so that the speaker produces sound in accordance with information containing the memory unit.
