Headset for use with a radiotelephone
First Claim
1. A headset for use with a radiotelephone, comprising;
- a connector for attaching to a jack of the radiotelephone;
a cord, having a plurality of conductors, having a first end attached to the connector;
a housing connected to a second end of the cord, having a speaker connected between a first conductor leading to the radiotelephone'"'"'s audio output and a second conductor leading to the radiotelephone'"'"'s ground;
a pivot connected to an end of the housing having a switch, the switch connected at a first end to the second conductor leading to the radiotelephone'"'"'s ground;
a boom connected to the pivot at a proximal end and having a microphone at a distal end of the boom, said microphone electrically connected at a first end to the second end of the switch and at a second end to a third conductor leading to the radiotelephone'"'"'s audio input and to an off-hook detection circuit; and
said switch having two states, open when the boom is aligned with the housing and closed when the boom is pivoted either clockwise or counterclockwise, wherein the microphone is in front of a user'"'"'s mouth.

Abstract
A headset (10) for a radiotelephone (12) has a boom (16) that pivots about a housing (13). The headset (10) has a speaker (20) and a microphone (18). A headset detect circuit (33) determines when the headset connector (24) has been plugged into the radiotelephone'"'"'s jack (26) and signals the microprocessor (60). The microprocessor (60) then connects the transmitter (68) and the receiver (70) to the headset'"'"'s microphone (18) and speaker (20). To answer a call the user rotates the boom (16), either clockwise or counter clockwise, which closes a three position switch (30) and sends an off-hook signal (44) to a microprocessor (60). To end a call the user rotates the boom (16) up so it is parallel with the housing (13)

5. A headset for use with radiotelephone, the headset comprising:
-
a housing; a pivot connected to the housing; a speaker proximally located near the pivot; a boom having two ends, wherein one end is connected to the pivot, the boom having a stored position and an active position when either rotated clockwise or counterclockwise from the stored position; a microphone located at the second end of the boom; a switch having two ends for electrical connection, wherein the speaker is connected to the first end of the switch and the microphone is connected to the second end of the switch, the switch further having an open state and a closed state, the open state corresponding to the stored position and the closed state corresponding to the active position; a capacitor; and a momentary switch connected in parallel to the capacitor; wherein the parallely connected capacitor and momentary switch are serially connected between the speaker and the first end of the switch.
