Abstract

The utility model relates to a telephone, which has similar shapes and functions as conventional telephones, is capable of being accessed to a computer, responding to incoming calls through network and giving out ringing, and receiving and sending voice messaging through network. The utility model comprises a telephone holder, a telephone handle and a control circuit arranged in the telephone holder. The control circuit comprises ringing amplifying circuit. An input end of the circuit is connected with ringing signal output by a sound card of a computer through a switch hook. An output end of an amplifier is connected with a ringing speaker. The control circuit is connected with an audio input end and an audio output end of the sound card of the computer through connecting wires and plugs. The plus 5V operational power supply of the amplifying circuit is provided by the power supply of the computer. A microphone and a receiver arranged on the handle of the telephone are connected with the audio input end and the audio output end of the sound card of the computer through a pressure spring switch, respectively. The telephone is an active telephone, and is capable of producing ringing tone according to call signal. The signal intensity of the telephone is the same with the signal intensity of normal telephones, accordingly, the telephone can be relatively far from the computer, and when someone calls, call receiver can receive the call in time. The way that users receive the call through the telephone is the same with the way that users receive calls through normal telephones, and it is very convenient to use the telephone, in particular for the elderly. Unlike normal urban telephones, the telephone does not adopt the power supply of the circuit, and is not provided with a power supply, and instead, adopts the computer power supply through a USB interface or keyboard interface. Accordingly, the telephone has simple structure.

Description

The active telephone set that is used for the network visual telephone communication

Technical field

The utility model relates to the telephone set that uses in a kind of network visual telephone communication, specifically a kind of profile and function and routine call machine are similar, can insert the incoming call of computer response to network and send ringing tone, and can answer and send voice messaging by network.

Background technology

At present, development such as the networking telephone, network visual telephone rapidly, still, generally all the use a computer sound card of configuration of the connecting device that is used for voice itself, carry out exchange of speech by external microphone and earphone, the calling of network is pointed out by the ringing tone that picture shows and sound card sends.Though the function of this its network communication of configuration can both realize, for ordinary consumer, with traditional telephone set always as difference is arranged, accept to get up to have certain obstacle, also have inconvenience in the use.Particularly, it is smaller generally to set the sound that sound card sends, and can only be around computer, can not be in indoor easy arrangement; Answer can not resemble random the routine call machine, convenient.

Though, the applicant has formerly designed a kind of telephone set that is used for network visual telephone, but because the phone support is that inactive component itself is not established ringing set, though so this technical scheme solved many defectives of the prior art, have more above-mentioned defectives.

Summary of the invention

The purpose of this utility model is exactly in order to overcome defective of the prior art, and a kind of active telephone set that is used for the network visual telephone communication is provided.

Goal of the invention of the present utility model is realized by following technical proposal.

The active telephone set that is used for the network visual telephone communication, comprise the control circuit in phone support, telephone handle and the phone support, it is characterized in that described control circuit comprises the ring amplifying circuit, the input of circuit connects the bell signal that computer sound card is exported by switch hook, and the output of amplifier connects ringing loudspeaker; Control circuit links to each other with audio frequency input, the output of computer sound card by connecting line and plug, amplifying circuit+the 5V working power provides by computer power supply; Microphone on the telephone handle and loud speaker are through audio frequency input, the output of hook switch difference computer sound card.

This telephone set is further characterized in that described amplifying circuit+5V working power links to each other with computer by standard USB port line.

The feature of this phone is that also described phone support is provided with earphone, Microphone, and it connects the computer sound card audio signal respectively by switch hook.

This telephone set is further characterized in that, described amplifying circuit+5V working power can also connect computer by standard computer keyboard port line.

Advantage of the present utility model is very outstanding, because this telephone set is for there being source telephone, self can produce ringing sound according to call signal, signal strength signal intensity is identical with plain old telephone, therefore, telephone set can have people's incoming call can in time notify from a phone call those who answer relatively away from computer; Mode and ordinary telephone set that the user receives calls are as broad as long, very easy to use, and be particularly just more acceptant for the elderly.This telephone set can not resemble the power supply on common local telephone network line taking road, self not charged again source, but get computer power supply by USB interface or keyboard interface, therefore make this telephone structure simple.

Description of drawings

Fig. 1 is the control circuit schematic diagram of the utility model telephone set inside.

Fig. 2 is the profile schematic diagram of the utility model telephone set.

Embodiment

Below in conjunction with the embodiment in the accompanying drawing the technical solution of the utility model is further specified.

As shown in Figure 1, the signal of computer sound card and USB interface inserts the CZ101 socket of telephone control circuit by connecting line, respectively with in the audio frequency output input signal of computer sound card and the computer power supply+the 5V power supply inserts phone.Audio signal is connected respectively to microphone and loud speaker on the telephone handle ,+5V power access circuit plate via switch hook K101 and socket CZ102.The audio output signal of computer sound card also is connected with the input of ring amplifying circuit by switch hook, the ring amplifying circuit is made of integrated circuit (IC) 1 (TDA2822M), its output connects ringing loudspeaker (or buzzer) the socket CZ104 on phone support, the power supply of integrated circuit (IC) 1 by USB insert+the 5V power supply provides.

As shown in Figure 2, profile of this telephone set and routine call machine basically identical, the external line of support comprise standard 3.5 plugs that connect computer sound card, and the patchplug that connects USB interface.

In order to adapt to the user who gets used to by headset or earphone receiving incoming call, this phone also is furnished with earphone and Microphone CK101, CK102 on the phone support.

When calling network, the bell signal that computer produces is exported to this phone by sound card, and the process amplifier sends the ring sound to the amplification driving buzzer of signal.At this moment the user clicks answering button and picking up telephone handle on the computer screen, just can converse as plain old telephone.If the user is ready that still by earphone, microphone conversation, telephone handle is used in perhaps long-time chat inconvenience, can connect earphone and microphone by the earphone on the phone support, microphone jack.

The supply power mode of the utility model telephone set can also can be extracted by computer keyboard interface+the 5V power supply by the USB interface among the embodiment, or other modes.By USB interface and its power supply of computer keyboard interface, should use the interface patchcord, can not influence the use of interface like this, patchcord and joint existing market all have sale.

It more than is description to technical solutions of the utility model and embodiment, rather than to the qualification of present techniques scheme, obviously realize that the invention has various ways, those skilled in the art can make various improvement according to content and spirit that the application's claim is limited.
