Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates generally to a luminescent external dialer
for mobile phone and, more specifically, to a hands-free unit for
mobile phone which includes a main unit and an external dialer.
The main unit is connected to a mobile phone, and the external dialer
is positioned in the car to allow easy operation for users. To ensure
effortless operation, the external dialer is equipped with dial
keys larger in size than regular ones and able to give light to
the dialing pad whenever there is insufficient lighting of surroundings.
As mobile telecommunication technology rapidly develops, wireless
communication devices such as mobile phones are widely used. Mobile
phone users demand a high performance from a portable phone to ensure
that they stay in touch while on the move. For mobile phone users
who drive, especially businesspersons who constantly drive at work,
safety is a great concern to them since they frequently have to
talk through the mobile phone while on the road.
Heretofore, it is known to construct a mobile phone plugged with
a hands-free unit, which typically contains an earphone and a clip-on
microphone. Drivers put on the earphone and the microphone at standby.
When receiving a call, users push the dial key to answer the call
or simply wait for the phone to automatically put them through after
a preset number of rings. The hands-free unit allows users to keep
their hands on the wheel and their eyes on the road, which helps
to decrease the risk of car accidents.
Although the heretofore known hands-free unit enhances convenience
and safety for mobile phones users, users still have to take the
mobile phone off the hands-free unit whenever they intend to make
an outgoing call.
Furthermore, since more and more mobile phones support Wireless
Application Protocol (WAP) functions, users would need to read information
or messages from the screen of the mobile phone when they surf on
the web. It is inconvenient for drivers to read the information
or messages from the screen when the mobile phone is placed on the
hands-free unit.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide
an advanced hands-free unit includes a main unit and an external
dialer. The main unit is connected to a mobile phone, and the external
dialer is installed in a proper position inside the car to allow
users to operate easily. To make operation even easier, the external
dialer is made with large dial keys and gives light to the key pad
whenever the lighting is insufficient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refer to FIG. 1, the present invention primarily includes a main
unit 1, and an external dialer 2. The correlative location and structure
of each component in accordance with the present invention are as
follows:
With reference to FIG. 2, the main unit 1 is connected to a mobile
phone 3 and having a voice-control circuit of hand-free set 11 and
a mobile phone charger circuit 12 while the voice-control circuit
of hand-free set 11 is connected with a microphone 11a as well as
a speaker 11b; the external dialer 2 is connected to the voice-control
circuit of hand-free set 11 of the main unit 1 and having a microprocessor
21, a liquid crystal display (LCD) 22, a brightness controller 23,
a keyboard 24, a luminescent panel circuit 25, a photosensitive
circuit 26, and a memory 27, wherein the microprocessor 21 is used
to control all internal circuits; the LCD monitor 22 for showing
signals of incoming calls or information is connected to the microprocessor
21; the brightness controller 23 for regulating the brightness of
the LCD monitor 22 is connected to the LCD monitor 22; the keyboard
24 for inputting dial information is connected to the microprocessor
21 and transmitting the information thereto; the luminescent panel
circuit 25 for increasing the brightness when the light in the environment
is insufficient is connected to the microprocessor 21; the photosensitive
circuit 26 connected to the luminescent panel circuit 25 can detect
the light in the environment in order to drive the luminescent panel
circuit 25; the memory 27 connected to the microprocessor 21 is
used to save preset parameters.
In accordance with the structure mentioned above, the main unit
1 is connected with the mobile phone 3 while the external dialer
2 is arranged at the location easy-to-reach for users thus the information
or phone number that users want to check or transmit is inputting
through the keyboard 24 on the external dialer 2. The signals then
are sent through the microprocessor 21, the voice-control circuit
of hand-free set 11 and finally to the mobile phone 3. Therefore,
the dialing process can be initiated through the external dialer
2.
Due to the easy-to-reach feature and larger liquid crystal display
22 on external dialer 2, users are much more convenient to input
signals without the trouble of looking for dialing keys.
Moreover, any information the user need can easily be checked because
the larger liquid crystal display 22 on the external dialer 2 which
is arranged on the location easy to manipulate. In addition, the
photosensitive circuit 26 of the external dialer 2 can detect the
light in the environment. If it's too dark, the luminescent panel
circuit 25 is triggered by the photosensitive circuit 26 to increase
the luminescence of the device so that users can dial or input messages
in the dark or gloomy surroundings.
Please refer to FIGS. 5 & 4, the main unit 1 includes an IR
receiver and the external dialer comprises an IR emitter. Thus the
external dialer 2 is attached to the main unit 1 in wireless way.
This is another embodiment of the present invention.
Many changes and modifications in the above-described embodiments
of the invention can, of course, be carried out without departing
from the scope thereof. Accordingly, to promote the progress in
science and the useful arts, the invention is disclosed and is intended
to be limited only by the scope of the appended claim. |
