Mobile Phone Patent Description
FIELD OF THE INVENTION
The present invention relates to a multiple functions transmitting
apparatus and especially to a multiple functions transmitting apparatus
for a mobile phone.
BACKGROUND OF THE INVENTION
The telecommunication industry expands very fast, and the wireless
telecommunication industry is growing especially rapidly. Every
telecommunication company is vying for a larger share of the market.
From the telephone system company to the telephone equipment maker
and further to the telephone service company, all the sectors of
the telecommunication industry are doing their best to win this
war.
In the wireless telecommunication field, data can be received and
transmitted via the wireless data transmission, such as the current
prices of stocks, E-mail, voice mail, information searches and so
on. Therefore, a telephone maker not only designs a mobile phone,
with the usual characteristics of being light, thin, short and small,
but also a mobile phone with pocket personal computer function,
dual-way transmission function and internet function.
Mobile phones are thus used not only for traditional voice transmissions
but also for data transmission. E-mail and image transmission in
mobile phones are increasingly popular.
In addition to wireless data transmission, the mobile phone provides
a transmission wire to input and output data and message. The transmission
wire supplies voice and data transmission, and further includes
the power supply. A traditional transmission wire includes a connector
with multiple parallel contacts or an earphone connector. Referring
to FIGS. 1A and 1B, FIG. 1A is a traditional mobile phone connector
with multiple parallel contacts and FIG. 1B is a traditional earphone
connector. The connector with multiple parallel contacts has the
functions of power supply, battery charge, handsfree headset, data
transmission interface, and peripheral device identification and
control. A connector with multiple parallel contacts is larger in
size and consequently higher in price. The contact quality of the
connector with multiple parallel contacts is sub-optimal, especially
when used while in motion.
The earphone connector is compact in size and has a better contact
quality. The earphone connector supplies a few functions such as
of power supply, handsfree headset, and simple data transmission,
but the earphone connector cannot provide the functions of battery
charge and peripheral device identification and control.
Hence, the mobile phone maker and users seek a connector which
can charge batteries and identify and control peripheral devices,
as well as be compact in size and have good contact quality.
SUMMARY OF THE INVENTION
One object of the present invention is to provide an earphone-type
of multiple functions connector with a compact size and good contact
quality.
Another object of the present invention is to provide an earphone-type
of multiple functions connector with functions of peripheral devices
identification and control.
A further object of the present invention is to provide a compact
size earphone-type of multiple functions connector for a mobile
phone with functions of peripheral devices identification and control,
as well as battery charge.
The present invention provides a multiple functions transmitting
apparatus of a mobile phone. The multiple functions transmitting
apparatus utilizes a tubal socket and a column terminal for connecting
a peripheral device with the mobile phone. The tubal socket comprises
a power contact point, an identification contact point, a first
signal contact point, a second signal contact point, and a ground
contact point. These contact points are positioned in the tubal
socket and isolated from each other. The power contact point supplies
an electric power between the mobile phone and the peripheral device.
The identification contact point identifies the type of peripheral
device. The first signal contact point and the second signal contact
point transmit signals for the mobile phone and the peripheral device.
The ground contact point is a system ground of the mobile phone.
The column terminal comprises an identification transmission contact
point, a first signal transmission contact point, a second signal
transmission contact point, a ground transmission contact point,
and a plurality of isolating elements. These contact points are
isolated by the isolating elements and these contact points and
these isolating elements are constructed the column terminal. The
identification transmission contact point has a recognizable shape
for identifying types of peripheral devices. The first signal transmission
contact point and the second signal transmission contact point transmit
the signal for the mobile phone and the peripheral device. The ground
transmission contact point connects the system ground of the mobile
phone. The column terminal further comprises a power transmission
contact point to supply power between the mobile phone and the peripheral
device. When the column terminal and the tubal socket connect together,
the contact points connect with each of the corresponding transmission
contact points. The identification transmission contact points for
peripheral devices of different types are provided with different
identifying shapes respectively to distinguish the different peripheral
devices.
When the identification transmission contact point has a small
diameter on the column terminal, the peripheral device is a microphone.
The mobile phone supplies power to the microphone by way of the
identification contact point and the identification transmission
contact point. The microphone belongs to a handsfree headset of
the mobile phone. The first signal and second signal are the right
and left audio signal of the handsfree headset.
When the identification transmission contact point has a normal
diameter, the mobile phone detects the voltage of the power contact
point. If the voltage of the power contact point is higher than
a predetermined voltage value, the peripheral device is a power
supplier to charge the mobile phone. If the voltage of the power
contact point is lower than the predetermined voltage value, the
peripheral device is determined according to a voltage signal of
the identification contact point. The voltage signal is set to different
corresponding voltage values for different peripheral devices respectively
to distinguish the peripheral devices. The power contact point also
supplies an electric power output to the peripheral device according
to the voltage signal. The voltage signal also includes a corresponding
digital signal of the peripheral device to distinguish the peripheral
device.
The tubal socket and the column terminal include a cylindrical
socket and a cylindrical column terminal, a square tubal socket
and a square column terminal, or a polygonal tubal socket and a
polygonal column terminal. The ground contact point further comprises
an electrical detecting device to detect types of the peripheral
devices.
Therefore, the multiple functions transmitting apparatus according
to the present invention can charge the battery of the mobile phone,
provide the power for the mobile phone, and identify and control
the peripheral device via a compact size connector with good contact
point quality, and the production cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following description is of the best presently contemplated
mode of carrying out the present invention. This description is
not to be taken in a limiting sense but is made merely for the purpose
of describing the general principles of the invention. The scope
of the invention should be determined by referencing the appended
claims.
FIG. 2 is schematic diagram of contact positions of the socket
of the multiple functions transmitting apparatus according to the
present invention. The socket of the multiple functions transmitting
apparatus is a tubal socket. The socket includes contact positions
210-250. The contact positions 210-250 show positions of the contact
points of the socket. By way of these contact points, the multiple
functions transmitting apparatus provides a power supply, handsfree
headset, data transmission interface, peripheral devices identification
and control, and battery charger.
FIG. 3A is a schematic diagram of one embodiment of the multiple
functions transmitting apparatus according to the present invention.
The embodiment is an input and output connector of handsfree headset.
As the drawing shows, the contact positions 310, 330, 340, and 350
correspond to the contact positions 210, 230, 240 and 250 (FIG.
2), respectively. In the practical function description, the input
and output connector includes a microphone contact point 302, a
first audio signal output contact point 304, a second audio signal
output contact point 306, a ground contact point 308, and a plurality
of isolating elements 360. The first audio signal output contact
point 304 and the second audio signal output contact point 306 output
the audio signals of right channel and left channel. The microphone
contact point 302 inputs the voice signal to the mobile phone and
the ground contact point 308 connects with the ground of the system.
The isolating elements 360 are utilized to isolate the contact points
from interference and shorts.
Comparing the contact points of FIG. 2 and FIG. 3A, the contact
position 220 of FIG. 2 connects no contact position of FIG. 3A when
the input and output connector of FIG. 3A is inserted into the socket
of FIG. 2. The contact position 220 is used to transfer the electric
power to/from the peripheral device. In this embodiment, the connector
lacks this function because the peripheral device is a handsfree
headset. Therefore, the connector is shorter than the socket to
avoid the connector contacting the contact position 220 of the socket.
The microphone contact point 302 at the contact position 310 is
obviously smaller than the other contact points of the connector.
The contact position 210 includes a mechanical detecting device
to recognize the peripheral device by way of identification of the
connector diameter. Therefore, the contact position 210 receives
an output voltage of about 1.2 V to 1.5 V for the microphone. By
way of detecting the size of the connector at the contact position
310, the contact position 210 switches different circuits to perform
different functions. For example, the signal from the contact position
310 transfers to the microphone circuit in the mobile phone when
the size of the contact position 310 is smaller. The working circuit
in the mobile phone changes to the other predetermined function
circuit when the contact position 310 is not smaller, such as the
embodiments of FIG. 3B and FIG. 3C. The contact position 310 can
push the contact position 210 out, and then a mechanical switch
changes the contact position 210 to connect the other predetermined
function circuit. Therefore, the mobile phone can distinguish the
different peripheral devices with different connectors.
Because of the skillful design thereof, the socket according to
the present invention is compatible with a traditional connector
of the handsfree headset. The traditional connector inserted into
the socket according to the present invention works smoothly. Therefore,
the multiple functions transmitting apparatus according to the present
invention has an excellent compatibility.
The contact position 330 connects with the contact position 230
to deliver the first audio signal to the earphone of the handsfree
headset. The contact position 340 connects with the contact position
240 to deliver the second audio signal to another earphone of the
handsfree headset. Hence, the mobile phone can receive the radio
signal and deliver the signal to traditional earphones connected
with the socket according to the present invention or traditional
earphones of the handsfree headset connected with the socket according
to the present invention, and then the user can hear a radio program
with the mobile phone having the socket according to the present
invention and the traditional earphone which has the traditional
connector. The contact position 250 connects with the contact position
350 to connect the peripheral device to the system ground.
FIG. 3B is a schematic diagram of another embodiment of the multiple
functions transmitting apparatus according to the present invention.
The embodiment is a connector of a power supplier. The connector
delivers the electric power for the mobile phone. The multiple functions
transmitting apparatus has different shapes such as a cylinder column.
The electronic parts of the mobile phone may be damaged if the other
contact positions, such as the contact positions 210, 230, 240 and
250, of the connector touch the power input contact point 316. To
avoid damage, the embodiment according to the present invention
hides the power input contact point inside the cylinder column.
Therefore, the power input contact point 316 can only connect with
contact positions other than the contact positions 210, 230, 240,
and 250, which is to say, contact position 220. The electronic parts
of the mobile phone are protected efficiently. In this moment, the
contact position 310 and the contact position 350 represent the
identification contact point 312 and ground contact point 314. In
this embodiment, the contact positions 210 and 250 include electronic
detecting devices, mechanical detecting devices or the combinations
thereof. The contact positions 210 and 250 detect and control the
actual peripheral devices connecting with the mobile phone. As in
the previous description, the contact position 210 with the mechanical
detecting device detects the cylinder column diameter at the contact
position 310 if the cylinder column of the connector inserts into
the socket. The detecting device finds the diameter is a standard
size of the cylinder column and not smaller. Therefore, the detecting
device recognizes that the peripheral device is not a microphone
and the contact position 310 need not deliver the electric power
for the microphone. The contact position 270 receives a 5-volt input
electric power and therefore the mobile phone switches to a power
input status to charge the batteries or directly use the electric
power.
FIG. 3C is a schematic diagram of a further embodiment of the multiple
functions transmitting apparatus according to the present invention.
The embodiment is a connector for electric power output and signal
input and output to provide the electric power for a peripheral
device and the data transmission between the peripheral device and
a mobile phone. When the contact position 210 finds the diameter
of the contact position 310 is a normal size and the contact position
220 does not receive an electrical power input, the contact position
210 switches to an electrical detecting device to detect whether
the contact position 310 is transmitting a voltage signal input
or not. If the contact position 310 is transmitting a voltage signal
input to the contact position 210, the electrical detecting device
at the contact position 210 further recognizes the type of the peripheral
device, such as a digital camera or an external bluetooth transmission
device according to the value of the voltage signal. Normally, the
contact position 250 is a system ground. The contact position 250
also includes an electrical detecting device to detect the type
of the peripheral device when the contact position 210 is set to
a system ground.
That is to say, if the diameter of the identification contact 322
is a normal size, not a smaller diameter, and the voltage of the
power output contact point 332 is smaller than a predetermined voltage
value, for example 3.2 V is smaller than a predetermined voltage
value 4.5V-5V, the contact position 210 detects the type of the
peripheral device according to the value of the voltage signal of
the identification contact point 322. For example, if the value
of the voltage signal of the identification contact point is about
3 V, the peripheral device is a digital camera, and if the value
is 4 V, the peripheral device is a bluetooth device. The electrical
detecting device of the contact position 210 can be a digital device
to detect the peripheral device according to the digital signal
from the identification contact point 322. After the type of the
peripheral device is recognized, the power output contact point
332 provides electric power to the peripheral device and the signal
input contact point 324 and the signal output contact point 326
provides the data transmission between the mobile phone and the
peripheral device. The ground contact point 328 is used to connect
with the system ground. The isolating elements 360 separate the
contact points. As in above description, the ground contact point
328 and the identification contact point 322 can be switched.
The present invention utilizes the mechanical detecting device
and the electrical detecting device to distinguish the peripheral
device. The cylinder column terminal and the tubal socket of the
multiple functions transmitting apparatus according to the present
invention provide more functions, better strength, better contact
quality and lower cost than the traditional connector does. Therefore,
the multiple functions transmitting apparatus according to the present
invention provides the functions of device identification, power
input and output, and data transmission for the mobile phone and
the peripheral device. Furthermore, the dimension thereof is compact
and convenient for the mobile phone. Hence, the mobile phone and
the peripheral device are easier to connect together. The terminal
and the socket are not limited to a cylinder column terminal and
a tubal socket. A square type or polygonal type also work well for
the present invention. As is understood by a person skilled in the
art, the foregoing preferred embodiments of the present invention
are illustrative of the present invention rather than limiting of
the present invention. It is intended that various modifications
and similar arrangements be included within the spirit and scope
of the appended claims, the scope of which should be accorded the
broadest interpretation so as to encompass all such modifications
and similar structures.
