Description

A kind of network telephone

Technical field

The utility model relates to a kind of computer network speech ciphering equipment, especially a kind of network telephone.

Background technology

Universal day by day along with the Internet especially broadband technology, development at full speed has appearred in network voice communication, use audio amplifier to add microphone or directly use headset to carry out voice-enabled chat from the individual, to USB network dial phone and voip phone technology, all brought economical and practical voice communication mode in various degree to people.But these several modes all have different problems and shortcoming: audio amplifier adds in the microphone mode, audio amplifier playback volume is too big, cause that easily feedback causes the echo of conversing, can produce audio amplifier when serious pipes, audio amplifier playback volume is not easy too greatly to maintain secrecy in addition, control owing to the distance between population and the microphone is difficult to stablize simultaneously, so that the sound that the other side hears is dynamic, is difficult to not hear; Though the headset mode can solve above-described subproblem, wear very inconvenience but frequently get, too for a short time being not enough to of ring sound makes us hearing during incoming call, giving answers the call brings difficulty, if in commercial environment or public place, the band headset is also inconvenient, is easy to be considered to be in the work hours chat on line; USB network dial telephone set can not solve sound interference and the privacy problem that the audio amplifier playback is brought equally, there is not audio amplifier can't obtain enough incoming call ring sound again, the price of this phone is also higher, be difficult to make ordinary consumer to be accepted, and this phone also needs to carry out software installation and debugging, using method more complicated; VoIP phone price is higher, and ordinary consumer only can be hung back.

Summary of the invention

The purpose of this utility model is to provide a kind of can overcome network telephone above-mentioned defective, simple in structure.

The purpose of this utility model realizes by following measure: a kind of network telephone, form by talking handle and base, be provided with loudspeaker and microphone in the talking handle, be provided with the conversation change-over circuit in the base, the conversation change-over circuit is a switching switch, its input is connected by lead with the microcomputer audio output interface, one output of diverter switch is connected by lead with the microcomputer audio amplifier, another output is connected with the talking handle inside trumpet, and microphone is connected by lead with microcomputer sound card microphone interface in the talking handle.

Also can introduce built-in speaker on the phone base, in order to replace the microcomputer audio amplifier.

Also can introduce the ear microphone standard interface on the phone base.

The utility model compared with prior art has the following advantages:

Audio amplifier ring when 1, sending a telegram here, audio amplifier no longer pronounces when proposing the machine conversation, thereby has not had the interference of feedback, makes the conversation echo be attenuated to bottom line, because audio amplifier no longer pronounces, so can maintain secrecy;

2, the utility model can be used for the network communication software of all current popular, need not the software installation and debugging, and is very convenient;

3, the communicate by letter telephone number resource of the company that can save of this mode is adopted by intra-company, reduces the holding time of telephone line;

4, talking mode is the same with ordinary telephone set, relatively is easy to be accepted by the people;

5, the utility model is simple in structure, and is cheap, is easy to be accepted by ordinary consumer.

Description of drawings

Fig. 1 is the utility model circuit structure block diagram.

Fig. 2 is the utility model electrical block diagram.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, network telephone is made up of talking handle 6 and base, be provided with loudspeaker 5 and microphone 4 in the talking handle 6, be provided with the conversation change-over circuit in the base, the conversation change-over circuit is one to switch switch 7, and its input and microcomputer audio output interface 2 are connected by lead, and an output of diverter switch 7 and microcomputer audio amplifier 1 are connected by lead, another output is connected with talking handle 6 inside trumpets 5, and microphones 4 and microcomputer sound card microphone interface 3 are connected by lead in the talking handle 6.When network telephone is in hook state, the computer audio frequency signal is sent to audio amplifier by audio output interface 2, audio amplifier playback operate as normal, during incoming call, audio amplifier sends the louder volume ringing tone, when replying, propose the machine conversation, the computer audio frequency signal is sent to talking handle 6 inside trumpets 5 by audio output interface 2, and audio amplifier audio signal source is cut off, so no longer playback of audio amplifier.

Also can introduce built-in speaker on the phone base, in order to replace the microcomputer audio amplifier.

Also can introduce the ear microphone standard interface on the phone base, be used to connect the integral type headset, be beneficial to extended telephone conversation under the environment that allows.

Claims (3)

1, a kind of network telephone, form by talking handle and base, be provided with loudspeaker and microphone in the talking handle, be provided with the conversation change-over circuit in the base, it is characterized in that: described conversation change-over circuit is a switching switch, in order to switch voice pathway, the diverter switch input is connected by lead with the microcomputer audio output interface, one output of diverter switch is connected by lead with the microcomputer audio amplifier, another output is connected with the talking handle inside trumpet, and the talking handle microphone is connected by lead with the microphone interface of microcomputer.

2, network telephone according to claim 1 is characterized in that also can introducing built-in speaker on the described phone base, in order to replace the microcomputer audio amplifier.

3, network telephone according to claim 1 is characterized in that also can introducing the ear microphone standard interface on the described phone base.
