Field of the Invention
This invention relates generally to the cellular telephone industry, and this invention relates in particular to a device for permitting the hands-free use of a cellular telephone while driving a vehicle.
Background of the Invention
Conventional cellular telephones have become extremely popular and indispensable communication tools for people who are constantly "on the go". While technology exists to permanently mount cellular telephones in vehicles, permitting users to utilize such devices while driving, most cellular telephone users use them, or at least need access to them, in locations other than their vehicles. Thus, the cellular telephone of choice to most users is a "portable" cellular telephone. Portable cellular telephones are primarily battery-operated, although technology exists to operate the telephone and/or charge the telephone's battery by connecting the telephone and battery to a power supply, such as a vehicle's cigarette lighter.
In the setting of a vehicle, however, portable cellular telephones are cumbersome, and potentially dangerous, to use. If the telephone is picked up only one hand. Often, in an effort to remain "hands-free", drivers support the telephone between the shoulder and the neck, which positioning tends to increase the possibility of accidents, as the driver's top priority should be operating the vehicle, and the effort to use the cellular telephone in a "hands-free" manner may pose additional dangers to the driver. In fact, certain jurisdictions throughout the world have proposed and/or enacted legislation prohibiting the use of cellular telephones in vehicles, to the extent that such use affects the driver's operation of the vehicle.
One possible manner in which to avoid the dangers of operating a vehicle while using a cellular telephone is to utilize a device which converts the telephone for use in a hands-free, or loudspeaker, environment. When such an accessory is installed in a vehicle and a portable cellular telephone is mounted thereto, it is possible to use a portable cellular telephone in a truly hands-free environment, as the portable telephone's microphone and speaker are linked to the same elements within the hands-free accessory.
