Description

TITLE OF THE INVENTION
Articulating Speaker and Microphone for a Wireless Telephone with Cigarette Lighter Adapter FIELD OF THE INVENTION
The present invention relates to the field of wireless telephony. More particularly, the present invention relates to an articulating speaker and microphone to be used with a wireless telephone in a hands-free manner, the speaker and microphone being provided on a cigarette lighter adapter.
BACKGROUND OF THE INVENTION
Since their introduction, wireless communication systems including pagers, cellular telephones and low-tier radio telephones, have become increasingly popular.
Such devices provide an extremely convenient means for communication .
Wireless telephone systems, for example, cellular telephones and low-tier radio telephones, are convenient because~they allow their users to save time. The user of a wireless telephone unit need not waste time looking for an available telephone in order to place a call.
Perhaps more importantly, a wireless telephone unit allows its user to take advantage of time spent traveling. For example, with a wireless telephone, the i user can be transacting business or making appointments while riding in a vehicle, walking down the street, or driving a car.
Another useful advance in the field of telephony is the invention of the speaker-phone. With a speaker-phone unit, the user speaks his or her comments aloud. The speaker-phone incorporates a relatively sensitive microphone, apart from the microphone in the handset, which transducer the user's comments. The speaker-phone then transmits those comments over the phone line in the conventional manner. Comments made by the other party to the phone call are produced by a speaker incorporated into the speaker-phone. In this manner, the user of a speakerphone has his or her hands free for other activities such as typing, note taking, etc. while engaging in the phone call. Speaker-phone units are now commonly used both at home and in the office.
As noted above, to maximize the advantages offered by a wireless telephone unit, the wireless unit should be useable while traveling, particularly while driving. As a user's hands are required for safe driving, it would be advantageous if a wireless telephone unit could be operated as a mobile speaker-phone. Accordingly, there is a need in the art for a method and apparatus of using a wireless telephone as a mobile speaker-phone while driving an automobile, and a need for a method of manufacturing the same.

Figure 8 shows a series of views of the articulating speaker and microphone of the present invention as it is articulated.
Figure 9 illustrates an alternative embodiment of the present invention.
Using the drawings, the preferred embodiments of the present invention will now be explained.
As shown in Fig. 1, the articulating speaker and microphone of the present invention includes a speaker 100 enclosed in a casing 108. Associated with the speaker 100 is a microphone 101. The microphone 101 is preferably disposed at the end of a microphone arm 102.
The microphone arm 102 is attached to the casing 108 with a hinge 103 about which the arm 102 may be rotated.

The speaker 100 and microphone 101 are connected to a wireless telephone unit (not shown) by the cable 106.
At the end of the cable 106 is a connector (See Fig. 5) which connects to a port of a wireless telephone unit.
When the speaker 100 and microphone 101 are connected by cable 106 to a wireless telephone unit, the wireless telephone unit may be manually or automatically switched into a "speaker-phone" mode:
In this speaker-phone mode, the wireless telephone unit will transduce a user's spoken comments with the microphone 101 and transmit those comments wirelessly in the conventional manner. The wireless telephone unit will also transmit comments received from the other party to the telephone call to the speaker 100 where the comments will be made audible to the user. In this way, the user may conduct a telephone call using his or her wireless telephone unit while leaving his or her hands free for other tasks, e.g. driving an automobile.
A problem arises in powering the relatively powerful speaker 100 and microphone 101. The battery of the wireless telephone unit would be quickly depleted if required to provide power to the speaker 100 and microphone 101. Accordingly, a cigarette lighter adapter 105 is provided. Using a well-known method, the adapter 105 converts the heat generated by a cigarette lighter in an automobile into an electrical current that can be used to power the speaker 100 and microphone 101.

i _8_ The adapter 105 is connected to the housing 108 with an articulating, semi-rigid extension 104 which incorporates a power cord connecting the adapter 105 to the speaker 100 and microphone 101. Due to the conventional placement of an automobile cigarette lighter on the automobile dashboard, it is convenient to have the housing 108, speaker 100 and microphone 101 supported by the articulating extension 104 and the cigarette lighter adapter 105. In this way, the speaker 100 and microphone 101 are suspended from the dash or console of the automobile relatively near the face of the user.
Further, the speaker 100 and microphone 101 are secured relative to the automobile by attachment to the dashboard or console via the semi-rigid extension 104 and adapter 105. This prevents the unit from moving or sliding away from the user as the automobile makes turns as would be the case if the unit were merely resting on the dash or passenger seat of the automobile.
While supporting the housing 108, speaker 100 and microphone 101, the semi-rigid extension 104 is also articulating. "Articulating" as used herein means that the extension 104 may be bent or twisted and will retain that bent, twisted form. In other words, the articulating extension 104 is constructed such that once it has been bent and/or twisted to reorient the speaker 100 and microphone 101, it will retain that shape and maintain the placement of the speaker 100 and microphone 101 until again reshaped by the user. Accordingly, the extension 104 may be articulated to move the speaker 100 and microphone 101 closer to the user. The extension 104 may also be articulated to optimally orient the speaker 100 and microphone 101 toward the user.
To perform as required, the extension 104 may be constructed in any of several ways including use of a continuous ductile metal tubing or a flexible conduit made up of a series of linkages which can be bent or twisted and will retain the resulting shape until moved again. Such supportive, flexible devices are commonly used to support and orient light sources in, for example, desk lamps. Preferably, the extension 104 is encased in a layer of flexible rubber.
Fig. 2 shows a right side view of an embodiment of the present invention. As can be more clearly seen in Fig. 2, the microphone 101 is supported at the end of a microphone arm 102. The microphone arm 102 rotates in the plane of the page of Fig. 2 about hinge 103 to bring the microphone 101 closer to the user. A finger catch 107 may be formed on the microphone arm 102 so that the user may more easily catch and pull the microphone arm 102 away from the casing 108.
Fig. 3 shows a rear view of this embodiment of the present invention. As shown in Fig. 3, and more clearly in the left side view of Fig. 4, the casing 108 may include a volume switch or dial 109 to control the volume of the speaker 100.
Fig. 5 illustrates another view of this embodiment of the present invention which includes the cord 106 and an electrical connector 110 for connected the speaker 100 and microphone 101 to a wireless telephone unit (not shown).
Fig. 5 also illustrates that the microphone 101 may be disposed an either the top or bottom of the microphone arm 102 relative to the power cord 104. If the microphone 101 is disposed at the lower end of the arm 102, as shown in Fig. 5, the arm 102 can bring the microphone 101 closer to the face of the user.
Fig. 6 illustrates the microphone arm 102, as oriented and hinged in Fig. 5, in an extended position.
The microphone 101 may be constructed so that when the arm 102 is moved away from the casing 108, the microphone 101 is automatically powered. Conversely, the microphone 101 may be automatically switched off when the arm 102 is in a folded position as illustrated in Fig. 5.
Fig. 7 contains first and second views of this embodiment of the present invention. In the first view, the semi-rigid, articulating extension 104 is straight.
In the second view, the extension 104 has been bent into an s-shaped configuration so as to better orient the speaker and microphone toward a user.

i Fig. 7 also includes an enlarged cross-sectional view of the extension 104. As mentioned above, the extension 109 contains a flexible conduit 112 which may be made of, for example, ductile metal tubing or a series of inter-connected linkages. The conduit 112 is preferably encased in a rubber casing 11 which may have wings 113 on either side to allow it to be more easily grasped and manipulated by a user.
Finally, Fig. 8 shows a series of three views of this embodiment of the present invention in which the invention is successively, inserted into a cigarette lighter 121 of the dashboard 120 of an automobile and then articulated to a desired position which optimally orients the speaker 100 and microphone 101 toward a user.
Fig. 9 illustrates an alternative embodiment of the present invention in which a microphone 201 is located along the cord 106 between the speaker 100 and the electrical connector 110 for connecting to a wireless telephone unit.
