Abstract

A device for producing a voice warning over a speaker which is also used with an entertainment sound production system such as a radio or cassette recorder. The voice warning device incorporates a switching device in the circuit between the speaker and a source of entertainment sound-bearing electric signals, and also incorporates a mechanism for selectively generating electric signals representing human voice sounds for conveying warnings. When a warning signal is being generated, the switching device is switched over from its state where it connects the speaker to the entertainment sound-bearing electric signals to its state where it connects the speaker to the warning signals. Optionally, several different speakers of an entertainment system may be selectively connected to said warning signals by several switching devices.
