housing of mobile phone.
Mobile Phone Patent Claims
What is claimed is:
1. An electroluminescent device for a mobile phone comprising:
a controller including a signal receiving unit, an electroluminescent
means flashing and driving controller unit, and a driving unit being
electrically connected sequentially; and an electroluminescent means
provided on the surface of the mobile phone being electrically connected
to the controller circuit; wherein the electroluminescent device
and the mobile phone have a common power source, the signal receiving
unit being used for receiving signal of an incoming call, said signal
receiving unit having a transistor which is activated when a signal
with frequency range of 800-1,900 MHz is received thereby causing
a capacitor to negatively trigger, the electroluminescent means
flashing and driving controller unit having an end triggered to
drive a plurality of transistors sequentially and therefore performing
a switching periodically wherein each of the plurality of transistors
is activated in a predetermined time frame while any of two adjacent
time frames is spaced by a predetermined time, a driving signal
being sent to a frequency changer circuit when a driving end of
the electroluminescent means flashing and driving controller unit
is activated, thereby creating flashing effect on the electroluminescent
means is when an incoming call is received.
Mobile Phone Patent Description
FIELD OF THE INVENTION
The present invention relates to an electroluminescent device and
more particularly to an electroluminescent device for communication
apparatus of mobile phone for informing an incoming call.
BACKGROUND OF THE INVENTION
Conventionally, a relatively loud, resonant sound is given for
informing user when an incoming call is received. An improved technique
is to show the number of calling person on display unit of mobile
phone when such occurs. However, these two conventional techniques
are somewhat monotonous. Further, the color of mobile phone is of
single color in most cases, while a few mobile phones are colored.
But these are unsatisfactory for the purpose for which the invention
is concerned because there is no flashing features available on
the mobile phone in the above techniques. Thus improvement exists.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an
electroluminescent device for communication apparatus of mobile
phone for informing an incoming call for carrying out a flashing
effect on the mobile phone when such occurs.
To achieve the above and other objects, the present invention provides
an electroluminescent device for communication apparatus of mobile
phone for informing an incoming call comprising an electroluminescent
means and a controller circuit wherein the controller circuit includes
a signal receiving unit, an electroluminescent means flashing and
driving controller unit, and a driving unit being electrically connected
sequentially; and the electroluminescent means is provided on the
surface of mobile phone being electrically connected to the controller
circuit. This also provides a personalized housing of mobile phone.
The above and other objects, features and advantages of the present
invention will become apparent from the following detailed description
taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front view of a preferred embodiment of electroluminescent
device of the invention, where no phone call is received;
FIG. 2 is similar to FIG. 2, where a signal is received;
FIG. 3 is a block diagram illustrating the invention shown in FIG.
1; and
FIG. 4 is a detailed circuit diagram of the invention shown in
FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1-2, there is shown an electroluminescent device
for communication apparatus of mobile phone for informing an incoming
call constructed in accordance with the invention. As shown in FIG.
1, mobile phone 1 is dimmed due to no phone call. In contrast, an
incoming call is received as such a flashing effect is carried out
on phone 1 (FIG. 2). The details thereof is as follows.
FIG. 3 illustrates the units effecting the invention comprising
a controller circuit including a signal receiving unit 10, an electroluminescent
means flashing and driving controller unit 11, and a driving unit
12 being electrically connected sequentially; and an electroluminescent
means 20 provided on the surface of mobile phone 1 being electrically
connected to the driving unit 12.
FIG. 4 illustrates the operations of circuits of the invention.
Note that the electroluminescent device of the invention and mobile
phone have a common power source. The signal receiving unit 10 functions
as receiving signal of an incoming call. That is, transistor Q7
is activated when a signal with frequency range of 800-1,900 MHz
is received by signal receiving unit 10. This activation further
causes capacitor C4 to negatively trigger. Then OS end (labeled
5) of the electroluminescent means flashing and driving controller
unit 11 is triggered to drive transistors Q1-Q5 to operate sequentially.
That is, perform a switching periodically wherein each of the transistors
Q1-Q5 is activated in a predetermined time frame, while any of two
adjacent time frames is spaced by a predetermined time. CNTL end
(labeled 11) is a driving end. A driving signal is sent to a frequency
changer circuit 13 from CNTL end when the CNTL end is activated.
As such, capacitors C1, C2 and transistor Q6 are oscillated to activate
to cause transformer T1 to increase voltage periodically. As a result,
driving unit 12 is activated to create flashing effect on electroluminescent
means 20. Thus user may see mobile phone flashing when an incoming
call is received.
While the invention herein disclosed has been described by means
of specific embodiments, numerous modifications and variations could
be made thereto by those skilled in the art without departing from
the scope and spirit of the invention set forth in the claims.
