Abstract

A modular unit having a telecommunications component, a switching circuit, and a headset link is adapted for connection with a host electronic device. The headset link of the modular unit communicates with a module link in a headset. The headset also contains earphones or a speaker, a microphone, and a control panel in electrical connection with the module link of the headset. The speaker, microphone, and control panel of the headset communicate with the headset link of the modular unit through the module link in the headset. The switching circuit of the modular unit controls whether the headset link of the module is in electrical connection with the telecommunications component of the modular unit or an electronic audio component of the host electronic device.

Claims

5. The system as set forth in claim 1, wherein said means for communicating comprises a first infra-red transceiver and a second infra-red transceiver for communications with said first infra-red transceiver, said first infra-red transceiver being located in said modular unit and said second infra-red transceiver being located in said headset.

6. The system as set forth in claim 1, wherein said modular unit is of a PCMCIA standard.

7. A system comprising:

a host electronic system having;

a module port with a module connector;

an electronic audio component being electrically connected to the module connector;

a modular unit having;

a housing with a first end;

a system connector disposed on the first end of the housing for engagement with the module connector of said host electronic system;

a telecommunications transceiver for communicating input signals and output signals with one of a plurality of standardized wireless networks in accordance with at least one preselected communication standard;

a switch having a first input electrically connected to the telecommunications transceiver, a second input electrically connected to the electronic audio component of said host electronic system through the module connector and the system connector, and an output, wherein the output is selectively connectable to the first input or the second input;

a headset having;

a speaker;

a microphone; and

means for communicating between the output of the switch in said modular unit and the speaker and the microphone of said headset.

8. The system as set forth in claim 7, wherein said module port and said modular unit are of a PCMCIA standard.

9. The system as set forth in claim 7, wherein said headset further includes a keypad which provides control signals to the telecommunications transceiver of said modular unit through the means for communicating.

10. The system as set forth in claim 7, wherein said means for communicating includes a cable extending between said modular unit and said headset.

11. The system as set forth in claim 7, wherein said means for communicating includes a first infra-red transceiver in said modular unit and a second infra-red transceiver in said headset, wherein said first infra-red transceiver communicates with said second infra-red transceiver.

12. The system as set forth in claim 7, wherein said means for communicating includes a first short range radio transceiver in said modular unit and a second short range radio transceiver in said headset, wherein said first short range radio transceiver communicates with said second short range radio transceiver.

13. The system as set forth in claim 7, wherein said host electronic system includes a battery power supply, and wherein the telecommunications transceiver of said modular unit receives electrical power from said battery power supply through the system connector of said modular unit and the module connector of said host electronic system.

14. The system as set forth in claim 13, wherein said module port and said modular unit are a modified PCMCIA standard which includes power contacts for transmitting the electrical power from said battery power supply to said telecommunications transceiver.

15. The system as set forth in claim 7, further including an external power source for providing electrical power to the telecommunications transceiver of said modular unit through a power connector mounted on the housing of said modular unit.

16.
