Speech production circuit (seeing Figure 17) is after receiving the playback enabled instruction PS that is sent here by scanning commutation circuit (shown in Figure 16), select data P0～P5 according to the section of together sending here, automatically access the corresponding language content that solidifies section, through D/A switch, be reduced to analog voice signal, after filtering, be sent to volume automatic control circuit (seeing Figure 18), after selected one section word run through, send into sweep start instruction SS by the EOC shown in Figure 17 to the scanning commutation circuit again, and output stand-by state sign, enter stand-by state by tone playing state simultaneously.This speech production circuit unit is desirable from the commodity of professional producer or customized specially, (in the frame of broken lines).The pin of respectively holding among Figure 17 is: φ 1, φ 2 are clock source U1701 outward element ends, Fc1, Fc2 are playback filter U1704 external capacitor ends, AO is an audio signal output end, P/W is playback/stand-by state mark output end, EOC is a playback end mark mouth, and P0～P5 section of being is selected data input pin.Come the playback enabled instruction PS(logical one single impulse of self-scanning commutation circuit (Figure 16) playback enabled instruction mouth), enter speech production circuit (Figure 17) by playback start end PLAY, in sheet, produce tone playing state sign (logical one) and be sent to playback/stand-by state mark output end P/W through logic controller.Make address generator under the output signal in clock source triggers, carry out plus coujnt simultaneously, its counting output read-only memory in sheet provides low order address A0～A15, and the data that the high address A16～A21 of read-only memory selects data input pin P0～P5 to send here by section are determined.These data are come the mouth Q0～Q5 of counting machine U1609 in the self-scanning commutation circuit, 1 bit quantization language content data flow of read-only memory U1706 output is reduced to analog voice signal by D/A U1705, after filtering,, be sent to the audio signal input end of volume automatic control circuit (Figure 18) from audio signal output end AO output.When the carry end Oc of address producer U1703 output logic 1, represent that this section words just run through, this logical one is after logic controller U1702 handles, send into the logical one pulse by playback end mark mouth EOC to the sweep start instruction input end SS of scanning commutation circuit (Figure 16), and send into the logical zero level to the signal input end of volume automatic control circuit by playback/stand-by state mark output end P/W, this logical zero level makes the interior address generator zero clearing of sheet simultaneously and stops counting, make the speech production circuit withdraw from tone playing state, enter stand-by state.
The volume automatic control circuit of Figure 18 can be provided with the playback volume automatically according to background sound size in the operator's compartment, makes the driver under any circumstance can both not hear warning of newspaper value and language content that loud speaker sends.Take the microphone MIC of shock-absorbing measure installation to connect two five road level indication integrated package U18 two signal input part 1N1 and 1N2 and two internal amplifier signal output part OUT1, OUT2 through Resistor-Capacitor Unit, Exclusive-OR gate (XOR gate) U1801～U1808 that 7 bit level indication output end LD1～LD5, the LD1 ' of U18, LD2 ' warp are connected in series hand in hand is to analog switch SW1801～SW1808 output.The volume automatic control circuit comes down to an automatic volume potential device that is controlled by background sound size in the operator's compartment, it is with capacitor C 1806 input end just very, convergence point with each analog signal output of SW1801～SW1808 is a mouth, be serially connected with the voice signal path from the speech production circuit to power amplification circuit, and the operator's compartment background sound size of picking up according to microphone MIC, in SW1801～SW1808, connect certain switch rightly, thereby make loud speaker emit suitable volume, background sound is big, volume is then big, background sound is little, and volume is then little.U18(TA7666) be two five road level indicating circuits, in this circuit,, U18 used as the Dan Shilu level indicating circuit by suitably choosing the resistance value ratio of R1813 and R1814.Promptly at background sound from be minimal to maximum change procedure, if each mouth LD1～LD5 and LD1 '～LD5 ' all are connected to pull-up resistor, these 10 mouths of LD1～LD5 ' will become logical zero by logical one successively so, until complete be logical zero.Because the spot control form that this line output form and SW1801～SW1808 requires is not inconsistent, 8 Exclusive-OR gate (XOR gate)s of bonded assembly so the employing input end is handed in hand have been realized the conversion of line to point.
Because during the loud speaker playback, the sound of language or warning language also can be picked up by microphone MIC, and be used as background sound and treat, as not taking measures, the sound that loud speaker is emitted can be increasing in a word, therefore increased the control circuit of being made up of elements such as T1801, C1805, the point of connection of R1816, R1817 is controlled by playback/wait state mark output end P/W in the speech production circuit (Figure 17) as signal input end.During playback, P/W is not a logical zero, and T1801 is ended, and the anodal output signal of MIC can pass through C1801, R1801 and C1802, R1812 respectively and enter U18, and suitable volume is set, but loud speaker sounding not at this moment.When the speech production circuit enters tone playing state, P/W becomes logical one, make the T1801 saturation conduction, and utilize the output signal of C1805 short circuit MIC positive pole, so keeping under capacitor C 1803, the C1804 effect, on off mode when each switch keeping of SW1801～SW1808 has just begun playback makes volume constant, finishes until a word playback.
