[Technical field to which the invention belongs] The present invention relates to a small keypad operation mode or a set of keys set on an Internet telephone operation panel to complete the input of making a call, answering a call, and hanging up the volume of a voice. Disk, especially a small keyboard that can be switched between small key modes, and can use the two directions of the small key word, operation or function instructions, telephone and increase or decrease the sound source transmitter. [Previous technology] As usual on a desk There are things such as telephones, computer screens, computer hosts, documents, keyboards, or mice. However, in some occasions, users may only need to enter numbers or the & setting of the mobile cursor, and only use them. Generally, the numeric keypad, direction keypad or function keypad on the right side of the keyboard, so it will only place a small type of small input devices collectively called Keypad 1 as shown in Figure 1 for Instead of the numeric keypad area, directional keypad area or function keypad area on the right side of the main keyboard, as shown in Figure 3, so as not to occupy too much space. In addition, the current mainstream telephone systems are all through the Public Switched Telephone Network (PSTN) 'It is mainly performed by various national telecommunications bureaus or telecommunications companies to perform various circuit switching operations. "The line between the caller and the receiver is equal to a dedicated line. Therefore, the caller must pay according to the distance." If it is a cross-border communication, the cost will be staggering. Furthermore, when the company is processing audio, video or other information, , And a separate network must be deployed for round robin. And various networks have different transmission requirements, which makes them difficult to install and maintain.

200540683 V. Description of the invention (2) and the cost of reconfiguration is very high. Moreover, the software and hardware architectures of each network are quite different, making it difficult to integrate the networks with each other, thereby limiting their potential uses. However, in recent years, after the rise of the Internet, broadband networks have been installed in various parts of the world. People use various Internet Protocols (IP) to process voice, video, or other data. In the form of data packets, real-time voice, video, or other data transmission on the Internet has become an emerging technology. In terms of Internet voice transmission technology, it is composed of Internet Protocol phone, Voice over Internet Protocol (V〇ip) and several network devices (such as VoIP Gateway), etc. The voice received by the dial-out Internet phone will be digitized and compressed by the Internet language protocol, and then transmitted to the receiver through the Internet in a packet. After using the Internet language protocol to reverse the operation, you can hear the voice sent by the dial-out party, so as to perform the call function, so that users do not need to go through the traditional public The telephone network (PSTN) allows long-distance telephone conversations without the cost of long distance calls. However, if the company wants to change the traditional phone to an Internet phone, there are still Internet phones, computer screens, computer keys, documents, keyboards, or mouses on the desks, making the desks The location of the items' f has not been replaced by a traditional phone for Internet phone. @ Will leave no space. For users who need to use a large desktop, it is quite a problem, so if you can Putting Internet Phones and Must-Places on Your Desktop 1 Page 6

When the mode switching key 44 is pressed, the switching signal can be generated, so that the control unit 3 can be based on the switching signal. To switch the keypad between the symbol input operation mode, the Internet phone operation mode, or a computer phone operation mode, so that the key pulse signal generated by the rectangular circuit 28 in the subsequent operation can be determined according to the current operation mode, respectively. Send to the control list 70, keyboard module, Internet phone module or computer module for further processing. ~ When the number, direction and function key 40, operation symbol key 乜 and number lock key 46 are pressed, the rectangular circuit 28 will generate a corresponding key pulse signal and send it to the computer module 34, so that the The computer module 34 can generate various calculation signals according to the same pulse signals, and send them to the 忒 control unit 3, and then the control unit 3 generates corresponding display signals (such as digital display) according to the calculation signals. And calculation result display, etc.), and transmitted to the display 21, so that the display 21 can output a corresponding display day and time according to the display signal. In this embodiment, the key set 4 further includes a send key 41. After the send, 41 is pressed, the rectangular circuit 28 transmits the key pulse signal to the computer module 34, so that the computer The module 34 generates a sending signal for transmitting the data of the screen currently displayed on the display 21 to the electronic device through the port 20 for subsequent processing. In the embodiments, the casing 2 is provided with a light emitting element 25, and

Page 13 200540683 V. Description of the invention (ίο) After the digital lock key 46 is pressed, the rectangular circuit 28 transmits a corresponding key pulse signal to the control unit 3 'to cause the control unit 3 to generate a corresponding light emission f, And transmitted to the light-emitting element 25 'to change the light state of the light-emitting element U. In this way, the user can observe the light-like sorrow of the light-emitting element and observe that the number lock key 46 of the keypad is On or off. In an embodiment, the display 21 is provided with a first-operation-state display area 29, and the first-operation-state display is a first-come-first-come-not-received area 29 ', which can display different symbols for the second and second grips respectively. I 'a 1 or pattern, etc.), used to indicate the current operation of the keypad ^ Ϊ Ϊ' 々 After the mode switching key 44 is pressed, the control unit 3 can switch the signal, and the keypad is Switch between symbolic mode, working mode and computer operation mode, '=, Ϊ two / the switching signal' produces a corresponding-display message and sends it to the display 21, so that the purine bottle-suppress 0 彳 state display area 27 or the first-thumb-up makeup can make the first operation-like surface of state 21, so, = ′ Beishe area 29 'shows the operation state of the corresponding painting. # 了 From the §HAI display screen, it is observed that the keypad is currently in place to prevent the keypad from making up ## to cut off the call, and in the implementation of η ;: when the Internet phone signal is processed, the answer and interrupt key ^ The telephone circuit module 32 is in progress. The rectangular circuit 28 is at the-designation time. After the member breaks and presses for a period of time, it should be after the Internet telephone module 32 ... 罔: The ground pulse signal is transmitted to-dial After receiving the signal, the telephone module 32 will generate a corresponding call signal and stop the call. The electric activity module 32 cuts off the subsequent network power as described on page 14, 200540683. This mode allows the computer to input on the keyboard, and the transmitter sends out the network. The general calculation of the small keyboard with general small keys is more convenient and clear before the special operation group completes the numbers, the amount of calls received and the mathematical operations. The fifth is the invention description (11) In summary, the combined telephone The operation further includes counting and using the small function and other instructions to reduce the sound source to solve the problem between the keypads. Pressing, the special keypad of the present invention in the field of the present invention is designed to make the keypad even work again.
