20080057889
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. Referring to the drawing figures, like reference numerals designate identical or corresponding elements throughout the several figures.
In accordance with a preferred embodiment of the invention, there is disclosed a Cell Phone Holder and Transmitter and a method for using the same. The present invention comprising: a holder (1) coupled to retractable and expandable holder arms (2) comprising of holder arm pads (3) and cradle pad (8) that secure a cell phone, mp3 player or other transmitting device in place. The holder arms release (14) is to release the holder arms and to adjust the holder arms according to the size of the cell phone, mp3 play or other transmitting devices. Holder (1) is secured to the attachment by a mounting clip (9) and a gooseneck (10) with a fixed clip at the end.
The Cell Phone Holder and Transmitter is affixed in place by a mounting devices which consists of a mounting clip (9) and a gooseneck (10) with a fixed clip at the end, which can in inserted into the gap between the dashboard panel and the windshield panel. The ideal position of the Cell Phone Holder and Transmitter in a vehicle is the left-hand side of the driver above the left air outlet (in the countries where the drivers' seats are on the right hand side of the vehicles, the ideal position is the right-hand side of the driver above the right air outlet). This position is the least intrusive position which will not interfere with driver with any of his vehicle operations.
Power is controlled on or off by means of a power switch and FM frequency selection (11) and is powered by means of battery cells located within the holder's battery bay (13). Mode is selected by means of a mold switch (4) with indicator (5) denoting whether transmitter is in audio transmission mode or in cell phone mode. Audio signals are received either through the microphone clip (7) or via 3.5 mm jack (12). Audio signals are then transmitted via microphone transmitter antenna (6) to a nearby receiver whereby voice is amplified by speakers at a frequency at or between 88.1 and 88.9.
Any Radio Frequency (RF) source needs an antenna. The present invention utilizes a microphone transmitter antenna (6) as an external antenna. The transmission efficiency is increased via use of the external microphone transmitter antenna (6) and without increasing the overall output wattage. The signal strength at the receiver end is increased via the external microphone transmitter antenna (6). Said external antenna (6) is comprised of wiring with a length inversely proportional to wavelengths meeting maximum efficiency at frequency ranges at or between 88.1 and 88.9.
The internal circuits are modified to serve several purposes. A purpose of the modified circuits results in corresponding impedance values compatible with the selected frequencies at or between 88.1 and 88.9.
A microphone as used in other products in the market may pick up audio signals from nearby stereo speakers thereby leading to positive feedback which may result in echoes or other noises. By utilizing an external microphone transmitter antenna (6) as in the present invention, a negative feedback circuit is partially canceled out and feedback into a receiver or stereo system is eliminated.
Still other objects, features, and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of embodiments constructed in accordance therewith, taken in conjunction with the accompanying drawings.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
It will be appreciated by those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restricted. The scope of the invention described by the foregoing includes all changes that come within the meaning, range and equivalence thereof and is intended to be embraced therein.
