Mobile Phone Patent Description
FIELD OF THE INVENTION
The present invention relates to a mobile phone extension set,
and more particularly to a mobile phone extension set to which a
mobile phone is electrically connected to allow a user to receive
incoming calls, make outgoing calls, and talk directly on the extension
set instead of the mobile phone. The mobile phone extension set
provided by the present invention is also provided with means for
charging the mobile phone.
BACKGROUND OF THE INVENTION
A high quality voice communication through a mobile phone is available
in recent years due to the highly developed communication technology,
the governmental encouraging and open policy toward the radio-communication,
the widely established signal transmission networks, and the matured
satellite communication technology. The population of the mobile
phone users in the world has largely grown by several hundred times
compared to last a few years. Moreover, the mobile phone rate has
largely reduced to enable even wider utilization of the mobile phone.
As a great contrast to the mobile phone that has become a popular
means of voice communication for people in most areas, wire telephones
used in isolated areas, such as places deep in the mountains, usually
necessitate overhead wire works that are difficult, complicate,
inconvenient, and extremely expensive to complete. Most people living
or working in such isolated places can not afford the high cost
of building the overhead wires and are frequently forced to give
up the use of wire telephones. It is fortunately the mobile phone
could now be used in such isolated places or some underdeveloped
countries in which telephone cables are not available due to economical
and/or technical factors. A disadvantage of the mobile phone is
that it has not the extension function as regular wire telephone
sets. The mobile phone usually includes only one single unit for
use by one person at a time, and there is not any mobile phone extension
set to allow the mobile phone to be used by more than one user at
different places and times.
In view of the difficult overhead wire works of the wire telephones
in isolated mountain areas, as well as the fact that no extension
set is available for current mobile phone, it is tried by the inventor
to develop a mobile phone extension set in an attempt to integrate
the good communication function of the mobile phone with the convenient
extension function of regular wire telephones, so that the mobile
phone is suitable for areas that could not be conveniently contacted
through wire telephones.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a mobile
phone extension set. The extension set mainly includes a regular
telephone set that is particularly provided with a signal bus for
receiving and transmitting various function signals. The mobile
phone could be electrically connected to the signal bus of the extension
set via a signal line. The extension set of the present invention
is also provided with a charger for directly charging the mobile
phone on the extension set. Therefore, any incoming and outgoing
calls to and from the mobile phone may be answered and made, respectively,
through the regular telephone of the extension set instead of the
mobile phone. Moreover, more than one extension set may be electrically
connected to the mobile phone depending on actual need to expand
the extension function thereof.
Another object of the present invention is to provide a mobile
phone extension set. The extension set is a regular telephone set
having a slot for a mobile phone to position therein to electrically
connect to the extension telephone set. The slot is provided with
a number of contacts for correspondingly transmitting various function
signals between the mobile phone and the extension telephone set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 1 and 2 that are block and circuit diagrams,
respectively, of a mobile phone extension set according to a first
embodiment of the present invention.
As shown in the diagrams, the mobile phone extension set of the
present invention mainly includes a telephone set 1 on which a signal
bus 11 is particularly provided. The signal bus 11 has a number
of pins to separately correspond and electrically connect to a ringer
2, a keypad 3, and a receiver 41 and a microphone 42 of a handset
4 of the telephone set 1. The telephone set 1 is also provided with
a mobile phone slot 6 into which a mobile phone 7 can be removably
positioned. A signal line interconnects the mobile phone 7 positioned
in the slot 6 to the signal bus 11. The telephone set 1 is further
provided with a charger 5 that supplies a servo power to charge
the mobile phone 7 via a conductor.
In the above-described mobile phone extension set, the mobile phone
7 and the telephone set 1 are designed to be two separable units.
That is, the mobile phone 7 is an individual unit that could b e
used independently. However, the telephone set 1 is functionally
workable only when the mobile phone 7 is electrically connected
to the signal bus 11 on the telephone set 1. The slot 6, in addition
to be used for holding the mobile phone 7 therein, also has several
contacts for separately electrically connecting to the ringer 2,
the keypad 3, the receiver 41 an d the microphone 42 of the handset
4, and the charger 5. Whereby, when the mobile phone 7 is correctly
positioned in the slot 6, various function signals could be transmitted
from the mobile phone 7 to the telephone set 1, making the telephone
set 1 functionally workable.
When the mobile phone 7 positioned in the slot 6 is induced by
an incoming call signal, the received signal is decoded into a data
signal source that triggers a ringing signal. The ringing signal
is transmitted via the signal bus 11 to actuate the ringer 2 for
the ringer 2 to ring. The received signal source is transmitted
via the signal bus 11 to the keypad 3 and waits for a confirmation
of the signal. Once correct keys on the keypad 3 are duly depressed
to confirm reception of the received signal source, another signal
is fed back to the mobile phone 7 to indicate the incoming call
has been connected. Meanwhile, the ringer 2 is disconnected and
the receiver 41 and the microphone 42 of the handset 4 are enabled.
At this point, a phonic signal source of the incoming call is converted
into an alternating voice source through a digital to analog conversion.
The alternating voice source is transmitted via the signal bus 11
to the receiver 41 of the handset 4. On the other hand, a voice
to be transmitted passes the microphone 42 of the handset 4 and
is converted from a voice source into a phonic source signal that
is transmitted via the signal bus 11 to the mobile phone 7. In the
mobile phone 7, the phonic source signal to be transmitted is converted
into frequency waves through an analog to digital conversion and
is then transmitted via an antenna on the mobile phone 7.
And, to make an outgoing call, first pick up the handset 4 and
dial a desired phone number and confirm the transmission of the
call by depressing suitable keys on the keypad 3. At this point,
the phone number input via the keypad 3 is encoded to provide a
digital signal that is transmitted via the signal bus 11 to the
mobile phone 7. The digital signal is converted into frequency waves
in the mobile phone 7 and is transmitted via the antenna of the
mobile phone 7. And, at the same time the transmission of the input
phone number is confirmed, the receiver 41 and the microphone 42
of the handset 4 are enabled for users to talk over the telephone
set 1.
It is to be noted the connection of the signal bus 11 to the mobile
phone 7 via a signal line is not the only way to enable the telephone
set 1. As shown in FIG. 3, it is also possible to have various function
signals for the telephone set 1 all directly sent to a number of
contacts provided in the slot 6 corresponding to, for example, the
ringer 2, the keypad 3, and the receiver 41 and the microphone 42
of the handset 4, so that signals may be directly transmitted from
and received by the telephone set 1 when the mobile phone 7 is positioned
in the slot 6.
With the above arrangements, when the mobile phone 7 is electrically
connected to the extension set, that is, the telephone set 1, the
telephone set 1 could be directly used to receive any incoming call,
to make any outgoing call, and to connect to any number of extension
telephone sets depending on actual need, as shown in FIG. 4. That
is, the telephone set 1 with the mobile phone 7 positioned in the
slot 6 not only could be used as a regular telephone set but also
could have any number of extension telephone sets connected to it.
In the case only one single telephone set 1 according to the extension
set of the present invention is provided with multiple regular extension
telephone sets connected thereto, a use mode of one single mobile
phone/multiple phone lines is available. And, in the case multiple
telephone sets 1 according to the present invention are provided
with or without regular telephone sets connected thereto, multiple
mobile phones 7 may be separately positioned in the slots 6 of these
telephone sets 1 to allow a use mode of multiple phones/multiple
phone lines.
As described above, the present invention integrates the communication
functions of a mobile phone with the extension function of regular
wire telephone. For an isolated place or any underdeveloped country
where regular wire telephones could not be conveniently mounted,
the present invention is well suited for use to replace the wire
telephones.
What is to be noted is the form of the present invention shown
and disclosed is to be taken as a preferred embodiment of the invention.
Various changes in the shape, size, and arrangements of parts may
be resorted to without departing from the spirit of the invention
or the scope of the subjoined claims. |
