1. Technical Field
The present invention relates generally to wireless headsets, and more particularly to a wireless headset to provide hands free use of cellular telephones and office phone systems.
2. Background Art
Cellular telephones are rapidly becoming the dominant means of telephonic communications. The freedom from wire-based systems provided by cell phones has enabled individuals to communicate with others while engaged in other activities, such as driving, walking, or (regrettably) eating. Studies are inconclusive on the dangers of talking on a cell phone while driving, but it is undeniable that having one hand and arm occupied with something other than vehicle control is less than perfectly safe. Accordingly, it is desirable to have means of using a cell phone while keeping both hands free to steer, shift gears, and manipulate buttons and knobs controlling various vehicle systems and devices, such as heaters, defrosters, mirror settings, and the like. Thus, reduce the risk of traffic accidents and to provide users with a more comfortable and convenient way to communicate with both hands free, several companies are manufacturing and selling phone headsets, some of which are adapted for use with wireless land phones, but some of which are also adapted for use with cell phones. A common alternative for use in the automobile is a phone speaker system.
Most current cell phone headset designs require a wired connection to a cell phone. The headset is plugged into an audio output jack and the cell phone is then placed in a convenient location. When driving, it is common to place the phone in one's lap, the adjacent seat, or an installed phone cradle. The wire provides a secure connection to the phone, and generally clear audio output, but the wire can pose as many problems to replace those purportedly solved by the headset. It can vex and annoy the user simply by being in the way—brushing across the face, dangling in front of and across the neck and arms. It can snag and suddenly pull the headset from the user's head, sometimes eliciting a grab response from the user, and this can be quite dangerous when it happens to the driver of a moving vehicle.
The most broadly marketed and widely adopted designs for wired and wireless headsets are of three types, including ear buds, over-the-ear, and headband-type. The first design, ear buds, include a speaker or pair of speakers disposed in small cylindrical housings inserted into the user's auditory canal. The housing is held in place only by the friction and pressure exerted on the user's auditory canal, and therefore it can be very uncomfortable and can easily be ejected or dislodged. Additionally, it has recently come to light that ear buds may cause hearing damage due to the retention of air pressure within the ear while in use. Further, ear buds are generally quite small and incapable of encasing the power source for driving the speakers. Therefore power is typically supplied through a wired connection to a base unit.
The second type of design, over-the-ear headsets, typically comprise an ear-clip type earpiece designed to be placed on, over, and at least partially around the user's ear. The earpiece includes a speaker held against and slightly inside the ear when the earpiece is placed on the outside of the user's ear. This type of headset generally solves the problem of discomfort, but they are not significantly more secure than ear buds. Further, they are generally adapted for use on only one ear (right or left), and they can be awkward and cumbersome to install.
A third design type comprises what are known as over-the-head headsets. These headsets typically employ a resilient arcuate head band which holds a speaker against, but outside, the user's ear. While generally slightly larger in size and weight, the headband type design is significantly more secure than either the ear bud or over-the-ear designs. The added security provides a measure of design flexibility in the placement of heavy electronics and power supplies. However, prior art designs generally provide an ear piece firmly pressed against the ear by the arcuate flexible headband, and after a period of use, this can become quite uncomfortable. Further, the known prior art designs do not disclose, teach, suggest, show, or otherwise render obvious a wireless headset having a selective on-off switch for the earpiece, an auto-off power saving circuit for the transmitter, or an auto-on/auto-off circuits for the transmitter.
The object of the present invention is to provide a wireless headset that enables cell phone users to talk hands free and without wires while driving or while engaged in any physical activity in which use of a conventional headset would be either dangerous or cumbersome. It provides a low cost solution to the problem of driving with a hand held cell phone.

The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
Referring to
The exterior side 150 of the headband annulus includes a channel 160 or other connection means adapted for swiveling connection to a combination earpiece/microphone member 170.
In the first preferred embodiment, the earpiece/microphone member includes an annular portion 180 having an interior surface 190 with connection means 200, preferably a plurality of projections or tongues 200, for matable snap-fit insertion into the channel 160 of the headband annulus. The annular portion forms a generally open interior area 185. Accordingly, the earpiece/microphone member may be rotated 360 degrees about the headband annulus. Numerous alternative means of coupling the headband annulus to the headset housing annulus are possible, including magnet surface-to-surface contacts, complementary hook and loop fastener material on each annulus surface, bayonet mounts, and so forth.
The earpiece/microphone member further includes an electronics housing 210 having a base portion 220 integral with the earpiece/microphone and extending inwardly from the annular portion of the earpiece/microphone annulus to the generally open interior area region 185 formed by the annular portion 180, and a cover portion 230 which snaps onto the base portion to create the open interior space or volume which houses the antenna, receiver, and transmitter electronics of the apparatus, none of which are described in detail in this application as all are well known in the art.
The earpiece/microphone member further includes a padded earpiece 240 disposed on the interior side 225 of the base portion and through which audio output is delivered by an earpiece speaker (not shown). A microphone arm or boom 250 extends outwardly from the housing, and a microphone 260 is disposed at the end of the boom and is in electronic communication with the transmitter electronics contained with the electronics housing 210.
