Description

Telephone automatically answering recorder and player

Phone automatic-answering back device videocorder be the Autoattendant that is used for phone reply and to calling record automatically, a kind of equipment of calling record, belong to the telephonic communication field.

Present widely used telephone set is a kind of ordinary telephone set that does not have automatic answer function, and when this telephone set was gone out nobody owner, then incoming call was unsuccessful, not only can not get any calling information, goes back busy trunk, and the whole call completing rate of local telephone network is reduced.Another kind of is the composite type dtelegraphone, and it mainly is made up of interface circuit, decoding circuit, recording/displaying device and telephone set, though this telephone set has the automatic answering machine function, costs an arm and a leg, and embarrasses generally national accept and popularize.With regard to present existing phone automatic-answering back device phonographic recorder, as Chinese patent application number be 92205019.8 and 92204215.2 phone automatic-answering back device phonographic recorder or device, they mainly exist the defective of following several respects: 1, owing to adopt solid-state memory, calling is become digital information leaves in wherein, just cause the number of times and the time of calling very short, generally be accumulated in 60 seconds, the content that surpasses then covers aforementioned content and eliminate, and cost is very high; 2, adopt magnetic recording, owing to limit the message time,, then can not all write down the utilance that has perhaps reduced tape in the message sometimes as 30 seconds or 60 seconds etc.; 3, telephone set can not write down the content of both sides' conversation when carrying out normal talking; 4, in phone automatic-answering back device Recording Process, do not have monitor function or in snoop procedure, can not mention the phone normal talking simultaneously; 5, tailored version often, and can not use as common recording playback machine.

The purpose of this utility model provide a kind of simple and reasonable, cheap, quiescent dissipation is little, multiple functional, supporting with telephone set, can play that phone automatic answering machine, telephone relation recording, phone automatic answering machine are monitored and the phone automatic-answering back device videocorder of common recording playback machine repertoire effect.

Fig. 1 is a theory diagram of the present utility model.It is made up of Input Interface Control circuit 1, single-tone decoding circuit 2, time-delay steady-state circuit 3, language generation circuit 4, audio amplifier circuit 5, power control circuit 6 and recording and playing device 7.
