Description

Numeral message recording machine of telephone

The utility model relates to a kind of phone automatic answering device, is specially adapted to digital phone message answer phone.

Phone automatic answering device of the prior art mainly is divided into two kinds, and a kind of is to be made of magnetic instrumentation tape, finishes the storage of speech signal by return to zero, as disclosed CN 90204517.2 patents of Patent Office of the People's Republic of China.There are the deficiencies such as wearing and tearing, mechanical aging and operation inconvenience of magnetic head, tape in this technology.Defectives such as another kind is to adopt the tape deck of sound-compound-circuit as voice signal in the message, and this technology in still exists the circuit structure complexity at present, and service behaviour is undesirable.

It is simple on a kind of structure that the purpose of this utility model is to provide, the digital phone message answer phone that service behaviour is good.

The utility model comprises the telephony interface control circuit, coupling circuit, speech processing circuit, voice record fragmented storage control circuit and operation keys logic control circuit.Wherein voice signal filter amplification circuit in coupling circuit and the speech processing circuit and the off-hook control connection in the telephony interface control circuit.Sound circuit is delivered to owner's message on the telephone wire by coupling circuit.The message of putting is also sent into the speech chip digitlization by the coupling circuit amplification, deposit digital code in memory.Be connected with speech chip with memory by the voice record segmentation control of operation keys logic control.The operation keys logic control circuit makes language fragments circuit selection memory, segment processing that language chip is left a message the owner of memory and the other side leaves a message.Connect reset, the operation keys logic control of recording, playback three push-button switches is connected with ring detecting circuit with speech chip respectively again.Press record button, owner's message is sent into the speech chip digitlization after the voice signal amplifying circuit amplifies.Press playback button and owner's message can be emitted the audition effect.Press reset key, device is in the unattended operation state, but the incoming call automatic off-hook is replied, and writes down the other side's message automatically.

Fig. 1 is an electric theory diagram of the present utility model.

Fig. 2 is phone coupling circuit embodiment.

Fig. 3 is that language record segmentation control circuit is implemented illustration.

Fig. 4 is that the operation keys logic control circuit is implemented illustration.

Fig. 5 is that external form of the present utility model is implemented illustration.

Fig. 1 is the utility model electricity theory diagram. This machine is typing owner message at first in actual use. Press record button, owner's message is sent into speech chip U1 digitlization by microphone MIC after the voice signal amplifying circuit amplifies, and the phonetic code after the digitlization deposits the U11 that selects through record segmentation control circuit in. U11 is set at owner's storage area of leaving a message. Press playback button and owner's message can be emitted audition effect, 16 seconds message time. Functional switch closure (ON) is pressed reset key, and this device is in the unmanned state, but complete rear automatic record the other side message is replied and replied to the incoming call automatic off-hook. After ring 2-3 time, ring detecting circuit output control signal triggers speech chip output off hook signal; The operated key logic control circuit makes the U11 in the voice segment circuit selection memory; Speech chip leaves a message the owner among the U11 and digital takes out, synthetic. Synthesized voice signal is sent into coupling circuit through filtering, amplification, by coupling circuit owner's message is delivered on the telephone wire. After owner's message discharged (16 seconds), speech chip sent " toot--" sound prompting the other side recording; While voice record segmentation control circuit selection memory U12, the other side's voice are by coupling Send into the speech chip digitlization after circuit, the amplification, and deposit digital code in U12. Record length 16 seconds. It is complete to record, and telephony interface control circuit automatic hand-up prepares to answer record next time. The same program is that the other side's recording is stored in the U13 memory for the second time. This device can arrange seven the other side's recording. If the voice memory block uses up, voice record segmentation control circuit cuts out, and no longer carries out recording operation. When owner answered a call recording, functional switch was opened (OFF), presses playback button, and the key logic control circuit triggers sound circuit and take out data from the U12 memory that the segmentation control circuit is selected, through promoting the loudspeaker playback after synthetic, filtering, the power amplification. Press playback button once, can hear first telephonograph, press again playback button once, listen second recording ... successively like this, seven telephonographs can be emitted successively. Press fast playback button, can be to recording substance quick-searching, selection, and can repeat to listen to certain section recording. This function is finished by operated key logic control circuit and voice record segmentation control circuit.
