As shown in Figure 1, the Internet phone terminal includes a compression spring unit, a ringing unit, a keyboard unit, a control unit, a handle unit, an external sound card unit, an information exchange unit, and a camera unit. in:

The compression spring unit is connected with the control unit, and is used for transmitting signals corresponding to the lifting and depression states of the compression spring to the control unit. The compression spring unit is a device with mature technology. The compression spring unit is located on the base of the phone. When the phone handle is placed in the base, the compression spring unit is pressed, and the circuit is connected to output a high-level signal to the control unit; when the phone handle is picked up, the compression spring unit The spring springs up, the circuit is disconnected and outputs a low-level signal to the control unit. Therefore, the control unit can know the state of putting down or picking up the phone handle by monitoring the level of the port connected to the compression spring unit. The schematic diagram of the compression spring unit is included in the diagram as shown in FIG. 2 .

The ringing unit is connected with the control unit and is used for receiving a signal from the control unit to ring. The ringing unit is a technically mature device. The control unit sends a waveform signal to the port connected to the ringing unit, and the ringing unit can be controlled to make a ringing sound/buzzer. Figure 3 shows a schematic diagram of the ringing unit.

The keyboard unit is connected with the control unit, and the keyboard unit is a keyboard matrix circuit that realizes the keys of the telephone, and is used to receive the user's key information and transmit it to the control unit. The keyboard unit is a device with mature technology. Considering that there are no more than 20 commonly used telephone keys, a 4×5 keyboard matrix circuit can be used to realize common telephone keys.

The control unit can collect the information of the compression spring unit and the keyboard unit through the above-mentioned connection relationship, and can also transmit the ringing control signal to the ringing unit. The diagram shown in Figure 2 includes a schematic diagram of the control unit.

The handle unit includes a loudspeaker and a microphone, which are respectively connected to the loudspeaker interface and the microphone interface of the external sound card unit. The external sound card unit emits sound through the speaker on the handle unit, and collects sound through the microphone of the handle unit. FIG. 4 shows a schematic diagram of the external sound card unit, and the external sound card unit shown in this figure is realized by a USB sound card.

The information exchange unit is connected with the computer, the external sound card unit, the control unit, and the camera unit, and is used to transmit the information issued by the computer to the corresponding units, and transmit the information reported by the external sound card unit, the control unit, and the camera unit to the computer. Thus, the information exchange between the Internet phone terminal and the Internet call software on the computer is realized. Figure 5 shows the schematic diagram of the information exchange unit. In this figure, the information exchange unit is realized by a USB hub (USB HUB). The USB HUB can send different types of information issued by the computer to different USB HUB ports. On the top, it is transmitted to different units to realize the distribution and exchange of information.

Figure 6 is a schematic diagram of the appearance of the telephone terminal of the present invention. As shown in Figure 6, the above-mentioned Internet telephone terminal is viewed from the outside, and its shell includes two parts: a handle and a base, which are connected by a flexible data line, wherein The data cable contains a plurality of wires inside, which are used as connecting wires between the circuit in the handle and the circuit in the base. The handle is used to realize the function of the handle unit; the base contains the compression spring unit, the ringing unit, the keyboard unit, the external sound card unit, and the information exchange unit. In addition, the above-mentioned Internet phone terminal may not include a ringing unit, and the ringing sound is simulated by the Internet calling software, and the sound is emitted through an external speaker connected to the sound card of the computer.

Before using the Internet phone terminal described in the present invention to make Internet calls, it is necessary to perform some necessary settings on the Internet call software on the computer connected to it, including binding the external sound card unit of the Internet phone terminal to be used by the Internet call software. The sound card can be bound by specifying the hardware address of the sound card. In this way, when the Internet calling software is activated, the sound provided by the Internet calling software is produced and collected through the external sound card unit in the Internet phone terminal bound to the software, and the sound card on the computer is avoided. It is also necessary to set the parameters required by the Internet calling software to establish an Internet network connection, such as network access number, user name, etc., so as to realize that after the Internet calling software is activated, it can automatically establish a connection with the Internet. It is not difficult to understand that these settings can also be automatically detected and configured by the software when the Internet calling software is installed, so as to realize the binding between the Internet calling software and the external sound card unit. How to set the software parameters is not the key point of the present invention and will not be described in detail.

The dialing process of the Internet phone will be described below by taking the Internet phone terminal composed of the schematic circuit diagrams in FIGS. 2-5 as an example. Referring to the dialing flow chart shown in Figure 7, after the Internet calling software on the computer has pre-set the necessary parameter configuration, the dialing process includes the following steps:

Step 701: The user picks up the handle from the base, the compression spring of the compression spring unit on the base springs up, and the compression spring unit outputs a low level to the control unit.

Step 702: The control unit detects that the compression spring springs up, sends out a call activation signal, and transmits it to the computer through the USB HUB, and the computer starts the Internet call software, and automatically establishes a connection between the computer and the Internet according to the pre-configured connection establishment parameters in the Internet call software , and use the USB sound card bound to the Internet calling software as the sound card used by the calling software during the Internet calling process. It is not difficult to understand that if the connection from the computer to the Internet has been established before step 701, then this step only needs to activate/start the Internet calling software.

Step 703: Then the user presses the called number and the call key through the keyboard unit, and the key code collected by the control unit is transmitted to the computer through the USB HUB.

Step 704: The computer's Internet calling software receives the key code information, and converts them into corresponding numbers (for example, corresponding to 0-9 numbers) or preset instructions (for example, the call-out key on the keyboard unit corresponds to the call-out instruction of the Internet call software) , initiate a call to the called user through the established connection to the Internet.

Wherein, in the process of making a call, the Internet calling software will call the audio file stored in the computer in advance to control the pronunciation of the USB sound card according to different states. For example: After the VOIP registration is successful, a waiting dial tone will be issued to notify the user that the call can be made. For another example, when the user presses a number key, there will be a key tone to inform the user that the key is successfully pressed. These sounds can realize the function of prompting the user to make a call when the computer is in a state of low power consumption or a black screen.

When the communication with the other party is successfully established, the IP data packet transmitted from the Internet is unpacked and restored to a sound file through the network call software, and then transmitted to the USB sound card through the USB HUB, and then transmitted to the built-in speaker of the handle unit to play; similarly, The user's voice is transmitted to the USB sound card through the built-in microphone of the handle unit, and then transmitted to the computer through the USB HUB, and then packaged and transmitted to the Internet through the network call software and sent to the other party. It is not difficult to understand that when there is a camera, the information of the camera is also transmitted to the Internet calling software of the computer through the USB HUB, and is packaged and sent to the other party together with the voice to realize the network video call.

When the call needs to end, the user puts down the handle, the spring of the spring unit is pressed down, and the spring unit outputs a high level to the control unit, and the control unit transmits the corresponding call end signal to the computer through the USB HUB, and the network call software receives it. End this call. At the same time, close the ports connected to the USB sound card and camera on the USB HUB. It is not difficult to understand that if the Internet calling software is pre-configured to automatically hang up the Internet connection, it is also necessary to disconnect the computer from the Internet at this time.

Referring to the answering flow chart shown in Figure 8, when the user is called, use the Internet phone terminal to receive the Internet call, including the following steps:

Step 801: The Internet calling software on the computer receives the call request, and the Internet calling software sends the ringing request to the control unit through the USB HUB, and the control unit sends a waveform signal to the ringing unit for ringing.

Step 802: The user hears the ringing, picks up the handle, the compression spring of the compression spring unit springs up, and the compression spring unit outputs a low level to the control unit.

Step 803: The control unit detects that the spring unit is popped up, and sends a signal to the computer through the USB HUB. After receiving the signal, the Internet calling software stops sending the ringing request and accepts the Internet phone call. At the same time, open the ports on the USB HUB connected to the USB sound card and camera, so that users can make online video calls.

It can be seen that when using the Internet phone terminal described in the present invention to cooperate with the corresponding Internet call software to make an Internet call, the user can make a call just like using an ordinary phone, without the need to operate the Internet call software, and when making an Internet call, It does not use the sound card of the computer to play and collect sound, but uses the external sound card unit in the Internet phone terminal to switch the sound to the handle of the phone terminal, ensuring the privacy of the user's conversation and will not interfere with the computer. playback of multimedia files.

In addition, to realize the present invention, as long as the computer can self-invoke the program, it has little relationship with the specific state of the computer. For example, when the computer is in a screen saver state or a low power consumption state, the steps of the present invention will not be affected. accomplish.

Wherein the above-mentioned Internet call may be an Internet call based on VOIP technology. The corresponding network calling software is VOIP calling software.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
