Description of drawings

Accompanying drawing is a circuit connection diagram of the present utility model;

Embodiment

Referring to accompanying drawing, the utility model adopts and is operated in the speech chip 1 that the direct addressing method model is ISD2590, the address wire A0-A9 of speech chip 1 and model are that the P0.0-P0.7 of single-chip microcomputer P0 mouth of AT89C51 and the P1.0-1.1 of P1 mouth are connected, and wherein A8-A9 has at least one to be 0.The recording playback model selection control input end P/R of speech chip 1, energy-saving mode control input end PD, chip selection signal input CE and overflow indicator input OVF are that the P1.2-1.5 of the single-chip microcomputer P1 mouth of AT89C51 is connected with model respectively.The end of message mark output end EOM of speech chip 1 connects the input INT1 end of external interrupt 1 that model is the single-chip microcomputer of AT89C51.The capacity coupler 1 that the output signal of speech chip 1 is made up of via capacitor C 7, resistance R 14 its SP+ end is connected with telephone wire with the signal amplification circuit of being made up of resistance R 11, NPN triode 2, the input signal of telephone wire connects the MIC end of speech chip 1 through capacity coupler 24, is that the single-chip microcomputer of AT89C51 determines whether to connect reproducing chain or recording chain by model.

In the use, the utility model needs the multistage suggestion voice, and the length overall of voice segments need be about 80s, and requires to play according to user's operation the order difference of voice.Speech chip 1 has the voice memory space of 90s, and multipotency divides 600 sections.By to the highest two control of address end, speech chip 1 can select to be operated in direct addressing method or other operator scheme.Speech chip 1 adopts direct addressing method in the utility model, as long as the initial address of voice is provided, cooperates speech chip 1 control signal, just can operate each section voice neatly.When the utility model needs playback, model is that the single-chip microcomputer of AT89C51 is provided with the initial address that needs the voice segments play in the speech chip by P0.0～P0.7 and P1.0～P1.1, by model is the operating state of the P1.2～P1.5 control speech chip 1 of the single-chip microcomputer of AT89C51, it is low making the economize on electricity control end PD of speech chip 1, recording playback pattern P/R is high, hold the low level pulse that adds more than the 100ns at chip selection signal CE, the utility model just begins to play voice.When this section speech play finished, the end of message mark output end EOM output low level pulse of speech chip 1 produced external interrupt 1, and model is that the single-chip microcomputer of AT89C51 judges according to external interrupt 1 whether voice segments finishes playing.After playback is finished, make its PD end, speech chip 1 is returned to electricity-saving state for high.When the utility model need be recorded, model is that the operation of single-chip microcomputer of AT89C51 is similar to playback, is that the economize on electricity control end PD of P1.2～P1.5 control speech chip 1 of the single-chip microcomputer of AT89C51 is low by model, and recording playback pattern P/R is low, chip selection signal CE end starts recording operation for low.Chip selection signal CE end need keep low level always, until End of Tape.Chip selection signal CE end then stops recording for high.Behind the End of Tape, envoy's electric control end PD is high, and speech chip 1 is returned to electricity-saving state.
