Abstract

A multi-purpose radio of the AC or battery operated type which includes connections for an auxiliary unit which is an alarm device of the ultrasonic type in which the transducers of the alarm device are mounted on the radio cabinet. The output of the alarm device is applied to the audio frequency amplifier section of the radio.

Claims

1. A combined radio receiver and alarm comprising

a radio cabinet,

power supply means within said cabinet

radio receiver means with said cabinet, said radio receiver means including audio frequency amplifier means and loudspeaker means connected to said audio frequency amplifier means,

alarm means including an ultrasonic transmitter and ultrasonic receiver means, located entirely within said cabinet, and

switching means which when placed in a first state electrically connecting said alarm means to said power supply means and said audio frequency amplifier means to activate said alarm means, said switching means including delay means which prevents the activation of said alarm means for a predetermined time after said switching means has been placed in said first state.

2. A combined radio receiver and alarm as in claim 1 wherein said alarm means includes amplifier means coupled to said ultrasonic receiver for amplifying the signals received thereby, said delay means including means for blocking the operation of said amplifier means during said predetermined time.

3. A combined radio receiver and alarm as in claim 1 further comprising means accessible from the outside of the radio cabinet for controlling predetermined time of inactivity of the alarm means as set by said delay means.

4. A combined radio receiver and alarm as in claim 1 further comprising plug means for connecting said audio frequency amplifier means to said loudspeaker means.

5. A combined radio receiver and alarm as in claim 1 wherein said ultrasonic transmitter and receiver means includes at least one transducer means which is mounted adjacent a wall of the cabinet.

6. A combined radio receiver and alarm as in claim 5 wherein said transducer means is mounted inwardly of the wall of the cabinet.

7. A combined radio receiver and alarm as in claim 5 wherein said transducer means is mounted substantially flush with the outer surface of said wall of said cabinet.

8. A combined radio receiver and alarm as in claim 5 wherein there are two ultrasonic tranducer means, one for the transmitter and the other for the receiver, which are mounted adjacent a wall of said cabinet.

9. A combined radio receiver and alarm as in claim 8 wherein said two transducer means are mounted at the lower corners of the first wall of the cabinet.

10. A combined radio receiver and alarm as in claim 3 wherein said accessible means for controlling the time delay comprises a knob.

11. A combined radio receiver and alarm as in claim 1 wherein said switching means comprises key actuated means.

12. A combined radio receiver and alarm as in claim 11 when said key actuated means is mounted on a wall of said cabinet accessible from outside of said cabinet.

13. A combined radio receiver and alarm as in claim 11 when said key actuated means is flush with the wall of the cabinet.
