Abstract
The utility model discloses a network telephone with Universal Serial Bus (USB) interface and computer sound effect card interface, which consists of a microprocessor having Universal Serial Bus (USB) function, an audio amplifier, a telephone speaker, press keys and a connecting plug. Through connection with a computer and running computer program, a user can make network phone calls by using the press keys of the network telephone and the utility model also has the functions of loudspeaker dialing, retention dialing and speech indication.
Description
Technical field
The utility model relates to a kind of network telephone, particularly can connect the telephone set that computer sound effect circuit and computer general serial interface (USB) interface are done the network voice communication.
Background technology
Network development at present is rapid, and the computer of general small-to-medium business all is the networking operation, so use network to make the utility function that speech communication can increase network, more can save the installation of inside line line in addition.But present apparatus structure complexity, expense are bigger.Goal of the invention
The purpose of this utility model provides the network telephone of a kind of tool general serial interface (USB) and computer adlib interface, by this device, the user can operate with the telephone set of custom, receive and get the networking telephone, this networking telephone comprises the inside line of computer to computer, computer is to the Internet Protocol telephone of computer, and computer is to the Intranet phone of phone; The utility model simple, with low cost, practical effect of structure of signing an undertaking.
Technology contents
The utility model comprises network telephone microphone, button, built-in sound receiver of phone transmitter and microphone, its network telephone has general serial interface interface and computer sound effect circuit interface, also comprises microprocessor, audio frequency amplifier and the connecting plug of tool general serial interface (USB) function simultaneously; Microprocessor is used to detect keying signal and keying signal is delivered to computer by general serial interface (USB) news road;
Audio frequency amplifier is used to amplify the audio signal from the output of computer sound effect circuit;
Phone transmitter is used to do voice call;
Button is used to make things convenient for user's operational network telephone set;
Connecting plug is used to connect general serial interface (USB) interface and the computer adlib interface of network telephone to computer.
Computer program is used for receiving the controlling signal from general serial interface (USB) interface, transfers speech sound signal to the IP packet and delivers to network and transfer speech sound signal again to from network reception IP packet.Technique effect
Install to computer when the user connects this, open the computer program of this device again, computer program meeting automatic detection device is also sent the audio frequency amplifier of speech sound signal to telephone set, notifies the user can use this device.
When the user wants to call to the other side, as long as the user hangs on, press number, the other side's networking telephone chance jingle bell, the bell that echoes that also can hear connection that user's the networking telephone is same.If the other side's computer not online (not connecting to network), user's networking telephone chance is heard busy tone, and operation is just like ordinary telephone set.
Because this installs most function all is the resource of utilizing in the computer, so hardware circuit is extremely simple, cost is cheap.This device also has elasticity with the communication of computer in addition, and the function increase and decrease only needs to revise computer programming and need not to revise hardware circuit, and the function expansion is extremely easy.
Description of drawings
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
Fig. 1 is the circuit block diagram of the utility model device.
Fig. 2 is the basic circuit diagram of the utility model device.
Fig. 3 is the system applies figure of the utility model device.
Embodiment
Shown in accompanying drawing 1, accompanying drawing 2, the utility model network telephone comprises: the microprocessor 1A of tool general serial interface (USB) function, audio frequency amplifier 1B, built-in loudspeaker 1C, the connecting plug 1D that is connected with computer, phone transmitter 1E and telephone key 1F etc.;
Tool general serial interface (hereinafter to be referred as: USB) the microprocessor 1A of function is by U1, X1, C1 and C2 form;
Built-in loudspeaker 1C is SP2;
The connecting plug 1D that is connected with computer is the SOC1 of 6 contacts;
Connecting plug 1D is connected to computer, and wherein 1 pin is connected to the input of computer adlib, and 2 pin are connected to the output of computer adlib, 3 pin are connected to the 5V power supply of computer USB interface, 4 pin are connected to the D-of computer USB interface, and 5 pin are connected to the D+ of computer USB interface, and 6 pin are connected to the ground wire of computer.
When the user will dial network telephone, the user hung on, and at this moment, microphone is connected to 5 pin by 6 pin of system SW1, and 18 pin of U1 transfer electronegative potential to by high potential.U1 can send the digital signal of off-hook after detecting this signal from D+/D-news road, this signal is delivered to computer through SOC1 4,5 pin.Receive this off-hook signal when computer program, it can produce the verbal announcement user and can dial phone number.2 pin of SOC1 can be delivered to from the computer adlib in these voice, through 3 pin of SW1, reaches the microphone that 2 pin are delivered to the user again.
When the user dials phone number, U1 can detect the keying signal of Key1, and U1 detects and can send the number signal from D+/D-news road behind this signal and deliver to computer through SOC1 4,5 pin.Receive this number signal when computer program, it just can connect the other side's network telephone, and the other side's network telephone just can jingle bell.
After 2 network telephones were connected, the user can pass through microphone MIC1 in a minute, delivers to the input of computer adlib through 1 pin of SOC1.The user just can transfer number to by computer program delivers to the other side's computer through network more in a minute.On the contrary, the numeral voice of being brought by the other side's computer can be exported to 2 pin of SOC1 by the computer adlib after the computer program decoding, delivers to user's microphone receiver SP1 again through 3 and 2 pin of SW1; At hook state, 3 pin of SW1 connect 1 pin, and 6 pin of SW1 connect 4 pin.When the bipartite network telephone set dialed into subsets, the user computer formula just can produce the tinkle of bells, and this tinkle of bells is delivered to 2 pin of SOC1 through computer adlib output, again through 3 pin and 1 pin of SW1, and C5, U2 and C9 broadcast at loudspeaker SPK2.This moment, the user can hear the tinkle of bells.
Accompanying drawing 3 points out how the present networks telephone set connects at a computer network system.As shown in the figure, computer network 3A is an intranet, and computer 3B, 3D interconnect through network 3A; Network telephone 3C is connected with computer 3B, and network telephone E is connected with computer 3D.When network telephone 3C dialed network telephone machine 3E, it was to connect by computer 3B, network 3A, computer 3D etc.
