Abstract
The utility model relates to a network telephone, which realizes talks via the internet. The inside of a casing is provided with a microprocessor and a keyboard which is connected with a circuit, wherein the microprocessor is connected with a computer via an interface, and a microphone and a pair of earphones are connected with the sound card of the computer. The means of dialing and answering IP calls of the utility model is similar to the means of dialing common telephones, and the utility model is very convenient to operate and conforms to operation habits. The utility model can be added with standard telephone circuits, and can make talks through common telephone net, and realizes that IP talks are diverted into common talks.
Description
Technical field: the utility model relates to communication device, particularly utilizes the device of internet conversation.
Background technology: the internet is popularized gradually now, and the particularly laying of broadband networks utilizes Internet phone-calling will progressively replace common telephone network.Use IP phone need utilize software now,, and need put on headset, manipulate obviously all being not so good as existing plain old telephone conveniently, do not meet people's the custom of answering with the computer keyboard input.
Summary of the invention: the utility model is to use inconvenience at existing IP conversation, designs a kind of use and answers conveniently, meets the network telephone of people's custom.The keyboard that the utility model is provided with microprocessor and is connected with its circuit at housing, microprocessor connects computer by interface, and microphone and earphone are connected with computer sound card.
The utility model housing can be designed to similar with ordinary telephone set or mobile phone, only need pick up a receiver during operation, keypad can dial, the information of dialling in is communicated with the other side IP address in machine parsing back as calculated, can equally with common phone converse, manipulate and the existing telephone basically identical, make things convenient for and meet people's habits and customs.
The utility model can connect the telephone set preferred circuit and connect microphone and earphone again on microprocessor, even computer is not connected with the internet like this, also can converse by common telephone network, and as long as the software that input is worked out in microprocessor, also can realize the function of IP phone transfer plain old telephone, do not wait for when computer is other the people, can guarantee contact.
The utility model also can connect display module by circuit on microprocessor, observe when being convenient to input signal, and same needs the software function setting also can realize caller identification, if the display module support also can demonstrate the name of incoming call side etc.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the circuit block diagram of embodiment;
Fig. 2 is the circuit connection structure figure of embodiment.
Embodiment: as shown in the figure, microprocessor adopts 8751, and keyboard is connected with its circuit, and for increasing the storage guiding, 8751 microprocessors also are circumscribed with memory, and the CS1611 display module also is connected on 8751 microprocessors.Microphone and earphone also are connected with computer sound card when being connected on the MC34014 call voice circuit, and the UM9125A dial-up circuit connects keyboard, and the H31002P ringing circuit connects 8751 microprocessors, connect common telephone network by the plain old telephone socket simultaneously.The communication of 8751 microprocessors and computer is undertaken by each standard interface, as serial ports, parallel port, USB mouth etc.Above-mentioned call voice circuit, rings telephone, dial-up circuit are telephone set preferred circuit commonly used, converse and send a telegram here ring etc. in order to connect common telephone network.
