ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a hand-free handset for use with a cellular telephone in an automobile, and more particularly to such a hand-free handset which can be installed in the driver's seat to suspend an ear phone and a microphone in the air near the driver's ear and mouth, enabling the driver to speak to a person over a cellular telephone without holding the cellular telephone in hand.
An automobile may be equipped with a cellular telephone rack for holding a cellular telephone. An automobile cellular telephone rack is generally mounted on the instrument panel. When the driver wishes to use the cellular telephone, the driver must control the steering wheel with one and, and operate the cellular telephone with the other hand. It is inconvenient and dangerous to use the cellular telephone when driving the automobile. There is known a wired microphone for use with a cellular telephone in an automobile. The wired microphone can be fastened to the driver's dress, so that the driver can speak to a person through the microphone over the cellular telephone. However, the electric wire of the wired microphone tends to be stretched and broken if the driver forgets to disconnect the wired microphone from the dress when leaving from the automobile.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. According to the present invention, the hand-free handset comprises a mounting device detachably fastened to one stem of the head rest of a vehicle seat, a tubular supporting member fixedly connected to the mounting device, an ear phone and a microphone fixedly mounted on the tubular supporting member, and an electric cable having one end fastened to the inside of the three-way tubular supporting member and connected to the ear phone and the microphone and an opposite end terminating in an electric connector for connection to a signal input/output port of a cellular telephone. The tubular supporting member can be bent to the desired shape, enabling the ear phone and the microphone to be suspended in the air near the user's ear and mouth.
