Abstract

A portable cordless telephone transceiver-radio receiver includes a headset which is driven by the audio output of a radio receiver until an incoming radio frequency (RF) telephone ring signal is detected by a telephone receiver. A telephone audio ring signal is generated based on the detected RF ring signal and the audio ring signal is converted to sound at the headset. The audio ring signal operates a latch which blocks or squelches the audio output of the radio receiver from the headset until the latch is reset. A "talk/off" switch is operated by the user to initiate and terminate conversation and to automatically reset the latch. In another embodiment, the radio receiver is squelched or turned off directly by the "talk/off" switch. In a further embodiment, the audio ring signal is blocked from the head set until a prescribed number of audio ring signals have been detected.

Claims

1. Portable cordless telephone transceiver-radio receiver comprising:

(a) a radio receiver circuit for receiving broadcast RF signals and for generating audio signals based thereon,

(b) a telephone receiver circuit for receiving broadcast RF telephone speech and ring signals and for generating audio speech and ring signals based thereon,

(c) a headset adpated to be coupled to said radio receiver circuit and to said telephone receiver circuit for producing sound based on said radio receiver circuit audio signals and said telephone receiver circuit audio speech and ring signals,

(d) settable/resettable blocking means for blocking said radio receiver circuit audio signals from reaching said headset when set and for passing said radio receiver circuit audio signals to said headset when reset,

(e) means for detecting presence or absence of said telephone receiver circuit audio ring signal and for automatically setting said blocking means when a telephone receiver circuit audio ring signal is detected, and

(f) operator manipulable switch means for resetting said blocking means.

2. Portable cordless telephone transceiver-radio receiver according to claim 1 wherein said blocking means includes a latch having an output coupled to a pair of switching transistors which pass or block the audio receiver circuit audio signals based on the latch output.

8. Portable cordless telephone transceiver-radio receiver according to claim 1 including a yoke associated with said headset, said operator manipulable switch means being mounted on said yoke.

3. Portable cordless telephone transceiver-radio receiver comprising:

(a) radio receiver circuit for receiving broadcast RF and for producing audio signals based thereon when power is supplied thereto,

(b) telephone receiver circuit for receiving broadcast RF telephone speech and ring signals and for producing audio speech and ring signals based thereon when power is supplied thereto,

(c) headset adapted to be coupled to said radio receiver circuit and to said telephone receiver circuit for producing sound based on said audio signals,

(d) first operator manipulable switch means for providing power to said radio receiver circuit but not said telephone receiver circuit when in a first position and for providing power to said telephone receiver circuit and to a second operator manipulable switch means when in a second position,

(e) second operator manipulable switch means coupled to said first operator manipulable switch means and said radio receiver circuit for completing a circuit path to said radio receiver circuit so at to provide power to the radio receiver circuit when in a first position and for opening said circuit path so as to cut off power to said radio receiver circuit when in a second position.

4. Portable cordless telephone transceiver-radio receiver circuit according to claim 3 wherein said circuit path includes a gate coupled to a transistor switch between said radio receiver circuit and said second operator manipulable switch means.

9. Portable cordless telephone transceiver-radio receiver according to claim 3 including a yoke associated with said headset, said second operator manipulable switch means being mounted on said yoke.

5. Portable cordless telephone transceiver-radio receiver circuit comprising:

(a) radio receiver circuit for receiving broadcast RF signals and for producing audio signals based thereon when power is supplied thereto,

(b) telephone receiver circuit for receiving broadcast RF speech and ring signals and for producing audio speech and ring signals based thereon when power is supplied thereto,

(c) headset adapted to be coupled to said radio receiver circuit and to said telephone receiver circuit for producing sound based on said audio signals,

(d) settable/resettable blocking means for blocking a preselected number of audio ring signals from said headset when reset and for passing audio ring signals to said headset when set,

(e) means for detecting a preselected number of audio ring signals and for setting said blocking means in response,

(f) first operator manipulable switch means for providing power to said radio receiver circuit but not said telephone receiver circuit when in a first position and for providing power to said telephone receiver circuit and a second operator manipulable switch means when in a second position,

(g) second operator manipulable switch means coupled to said first operator manipulable switch means for completing a circuit path to said radio receiver circuit so as to provide power thereto when in a first position and for opening said circuit path so as to cut off power to said radio receiver circuit when in a second position, and

(h) means coupled to said second operator manipulable switch means for resetting said blocking means so as to cause said blocking means to pass audio ring signals to said headset when said second operator manipulable switch means is in said first position.

6. Portable cordless telephone transceiver-radio receiver according to claim 5 wherein said blocking means includes a counter and a resettable latch connected thereto, and a pair of transistors connected to the output of said latch.

7. Portable cordless telephone transceiver-radio receiver according to claim 6 wherein said resetting means is connected between said latch and said second operator manipulable switch means.

10. Portable cordless telephone transceiver-radio receiver according to claim 5 including a yoke associated with said headset, said second operator manipulable switch means being mounted on said yoke.
