Mobile Phone Patent Abstract
A wireless mobile telephone capable of remitting picking up of an
earphone in use-but combining with car hi-fi speakers, which mobile
telephone applies an infrared transmission principle or a radio
transmission principle to transmit its received and emitting signals
to a car hi-fi set. Therefore, the car speakers can broadcast the
sound of the other side of the mobile phone call in remitting picking
up of the earphone. In this way, the mobile telephone not only has
the advantage of remitting picking up of the earphone, but also
can be extremely convenient in use by having no connecting wire
between the mobile telephone and the car hi-fi set.

Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mobile telephone capable of
remitting picking up of an earphone in use but combining with car
hi-fi speakers. And relates especially to a mobile telephone which
can transmit the received and emitting signals to a car hi-fi set
in a wireless mode, the sound of the user can be broadcast via the
car hi-fi speakers.
2. Description of the Prior Art
Users of mobile telephones in the present days know how to use
them without picking up earphones to ensure safety of car driving.
A conventional car mobile telephone remitting picking up of an earphone
in use shall have the mobile telephone mounted on a clamping seat
in order that the sound signal from the other side of the phone
call can be broadcast out of a speaker through a connecting signal
line. Such a single speaker transmits sound with inferior quality.
The sound is unclear and makes a user dislike.
Thereafter, some mobile telephones in the markets each provides
a circuit between a mobile telephone and a car hi-fi set and is
capable of remitting picking up of an earphone when in use. By providing
of the circuit in remitting picking up of an earphone, sound output
of the speakers can be controlled to emit the sound of the car hi-fi
set or the sound of the other side of the mobile phone call. This
is ideal at the first sight; however, it has a serious defect and
inconvenience, i.e., a user must connect his mobile telephone with
a connecting signal line once he gets in this car, otherwise, the
function of remitting picking up of an earphone will not work. While
in this quick pace of the industrial and commercial society, people
tend to not accept such a bothersome connecting operation, especially
those frequently get in and get out of their cars do.
In view of the above defects, the present invention is provided
after study, developing and improvement, it is more advanced, convenient
and faster for operation, for the goal of rendering the function
of remitting picking up of an earphone more ideal and perfect.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a mobile telephone
capable of remitting picking up of an earphone in use but combining
with car hi-fi speakers. The mobile telephone can transmit its received
and emitting signals to a car hi-fi set via an infrared or radio
transmitting device, so that the car speakers can broadcast the
sound of the other side of the mobile phone call in remitting picking
up of the earphone in use. And especially, a user needs not to connect
his mobile telephone with the car hi-fi set once he gets in this
car.
The present invention will be apparent after reading the detailed
description of the preferred embodiment thereof in reference to
the accompanying drawings.

a mobile telephone 2. Wherein, the electric circuit used in the
car hi-fi set 1 includes an infrared emitting device 110 and an
infrared receiving device 111 on the panel thereof. The signal transmission
card 21 on the mobile telephone 2 is also provided, in corresponding
to the infrared emitting device 110 and the infrared receiving device
111, with an infrared emitting device 210 and an infrared receiving
device 211. The mobile telephone 2 and the car hi-fi set 1 can get
the wireless transmission of signals therebetween by providing the
