ABSTRACT:
An audio reproduction system is provided for use in conjunction with a tombstone for the repeated playback, upon activation, of a prerecorded message. The system comprises a housing which is secured within the tombstone. A prerecorded message on an endless magnetic tape is operatively mounted within a tape playback device which in turn is contained within the interior of the housing. A Hall effect switch wholly contained within the housing activates, upon closure, a time module to operatively connect a self-contained source of electrical power to the tape playback device for the predetermined period of time. A solar cell is also operatively coupled with the electrical power source to supplement the same.
