Abstract
A combination radio (10) is provided for enabling the user to listen to two independent radio stations at one time. Alternatively, the combination radio (10) can be tuned into the same radio frequency to allow the user to combine the sound output from each individual radio. Moreover, additional radios can be added to the combination radio to increase the sound output of the system.
Claims17
An integral dual radio comprising:
- (a) an electrical power input;
- (b) an antenna;
- (c) a first independent electronic device for generating audible sound, the first independent electronic device having a first radio receiver, a first set of electronic controls including a first tuner control for tuning the first receiver, and at least one first speaker;
- (d) a second independent electronic device for generating audible sound, the second independent electronic device having a second radio receiver for receiving a radio signal independent of the first radio receiver, a second set of electronic controls including a second tuner control for tuning the second receiver to the same or different radio frequency as the first receiver, and at least one second speaker;
- the second independent electronic device generates audible sound through the second speaker which is independent of the first independent electronic device;
- and
- (e) a single, housing means enclosing and fixedly attached to the first radio receiver, the first set of electronic controls, the second radio receiver, and the second set of electronic controls;
- wherein the electrical power input and the antenna are electrically connected to the first and second independent electronic devices.
