Fig. 2 is the circuit block diagram of a kind of preferred embodiment of Fig. 1 block diagram.Frame of broken lines 4 is time dispensing controller among the figure, and it is made up of signal generator 401, rectangular pulse signal generator 402 and undersuing generator 404.After the energized, oscillation signal generator 401 produces oscillator signal and delivers to rectangular pulse signal generator 402, described rectangular pulse signal generator 402 is exported the wide rectangular pulse signal of constant amplitude on the one hand to undersuing generator 404, make the continuous undersuing of undersuing generator 404 output to microprocessor 3a and 3b to control its starting and to reset, described on the other hand rectangular pulse signal generator 402 is also exported a pair of anti-phase each other and continuity moment shaped pulse signal that constant amplitude is wide respectively to microprocessor 3a, 3b and two tunnels analogy on-off circuits 403, make microprocessor 3a and 3b under the control of this anti-phase each other signal, carry out " reading " respectively, " write " operation, make two passages of two tunnels analogy on-off circuits 403 be in " pass " respectively in turn simultaneously, " open " state, promptly when one of them microprocessor is in " reading " state, be in opening state with the corresponding passage of described microprocessor in this two tunnels analogies switch, and when this microprocessor was in " writing " state, described switch was in off state.Its concrete course of work is as follows: the simulating signal by input media 15 inputs becomes digital signal through the conversion of analog/digital converter, when microprocessor 3a is in " writing " state under the high level control that time dispensing controller 4 is exported, the digital signal that is become by analog signal conversion is deposited among the read-write memory 2a successively, meanwhile, microprocessor 3b is in " reading " state under the low level control that described time dispensing controller 4 is exported, digital signal among the read-write memory 2b is taken out successively, because with microprocessor 3b corresponding passage be in opening state in the two tunnels analogy switches 403 this moment, digital signal is input to D/A converter 5 by this switch, convert simulating signal to, through output unit 6 outputs.Described output unit 6 can be made up of for example electro-acoustic transducing device such as integrated power amplifier and loudspeaker; When time dispensing controller 4 is sent the next pulse signal, microprocessor 3a is in " reading " state under the low level control of time dispensing controller output, the digital signal that before write among the memory 2a is taken out, be reduced into simulating signal through output unit 6 outputs by digital to analog converter 5, meanwhile, microprocessor 3b is in " writing " state, will deposit memory 2b successively in by the digital signal that the input analog signal conversion becomes; When time dispensing controller 4 is sent the next pulse signal, the mode of operation of described two microprocessor 3a and 3b is opposite with a last impulse duration respectively, the state of promptly " reading " becomes " writing " state, the state of " writing " becomes " reading " state, the later course of work circulates according to this, all imports and delay time to export until simulating signal to finish.Can change delay time by the oscillation frequency that changes 401 output signals of oscillation signal generator.Adopt method of the present invention that simulating signal is delayed time, its distortion size only depends on the sample frequency of microprocessor, so distortion is very little, is generally less than 3%, and people's ear almost can not differentiated.Other parts among Fig. 2 are identical with Fig. 1, and are same if adopt language processor or integrated playback circuitry to replace microprocessor, then can save analog/digital converter and D/A converter, even can save memory.Undersuing generator 404 among the figure, oscillation signal generator 401, rectangular pulse signal generator 402 and analog switch 403 for example can adopt respectively, and CD4098, NE555, CD4027, CD4066 form, if adopt high-performance microprocessor, then also can save analog switch 403.Input media 15 can adopt for example microphone formation among the figure.
Fig. 3 is the circuit block diagram of the another preferred embodiment of the present invention.7 is chronotrons among the figure, the 8th, memory under program, its concrete course of work is as follows: after the energized, simulating signal by input media 15 inputs is transformed to digital signal through analog/digital converter 1, this moment, microprocessor 3 was in " writing " state, above-mentioned digital signal is deposited in the memory 2 successively, behind a predefined delay time, chronotron 7 sends a signal, memory under program 8 and microprocessor 3 are connected, microprocessor 3 is placed in " reading " state by getting instruction in the memory under program 8, and the digital signal in the memory 2 is read, and is reduced into simulating signal after output device 6 outputs by D/A converter.Under the control of memory under program, constantly from wherein obtaining " reading ", " writing " instruction, its read-write operation state just overturns once every the delay time of an equivalent microprocessor 3, finishes until whole inputs of simulating signal and time-delay output then.The delay time of described chronotron 7 can adopt in the present technique field the known method of people to regulate in wide region.
As far as possible little in order to guarantee distorted signals, the inversion frequency of the read-write operation of described microprocessor should be greater than four times of ordinary person's speech frequency.The embodiment of Fig. 3 compares with Fig. 2 embodiment, has few, the cheap advantage of device, though this stutter therapeutic equipment can not carry out write operation simultaneously when read signal, cause part signal to be lost, if but take higher sample frequency, then its distortion is that people's ear can not differentiated.In addition, if adopt language processor or integrated playback circuitry to replace microprocessor, then can save analog/digital converter and D/A converter among Fig. 3; If need not change after determining its time delay, then can save chronotron.
Fig. 4 is the schematic diagram of the another kind of embodiment of stutter therapeutic equipment of the present invention.It can by a closed magnetic memory body that can be recycled for example tape or disk etc. with have respectively read, recording playback mechanism, rotating mechanism and Input/Output Device that demagnetization, three magnetic heads of writing function are formed formed.Only partly show its recording playback mechanism among the figure.Wherein 10a is that initiatively guide wheel, 10b are that driven guide wheel, described active guide wheel and driven guide wheel have been formed rotating mechanism.The 11st, magnetic erasing head, the 12nd, write head movably, the 13rd, reading magnetic head, the 14th, closed magnetic memory body.Wherein, putting in order except that the mode shown in the figure of three magnetic heads also can be adopted record, reads, the arrangement mode of demagnetization.Its concrete course of work is as follows: after the energized, guide wheel 10a drives magnetic memory body 14 relative magnetic heads with 10b and makes at the uniform velocity shuttling movement.Write head 12 will be imported analog signal record constantly on magnetic memory body 14, when record on the magnetic memory body 14 has the position of described simulating signal to run to reading magnetic head 13, this simulating signal just is read out, and export through output device, subsequently, when record had the magnetic memory process magnetic erasing head 11 of this simulating signal, described signal was promptly wiped.Because magnetic memory body 14 is made operation with closed ring with respect to magnetic head, therefore the simulating signal of being imported constantly is recorded, reads and eliminates, and this process constantly circulates, and all input and time-delay output finish until simulating signal.The travelling speed of distance between change write head 12 and the reading magnetic head 13 or change rotating mechanism can change its delay time arbitrarily in wide region, the stutter therapeutic equipment distortion of adopting the method to make is little and delay time is long, so curative effect is fine.
In the design scope that claim of the present invention limited, those skilled in the art also can do some conspicuous changes to the foregoing description, but these changes all should fall within the protection domain of claim of the present invention.
