Abstract
The utility model relates to a speech controller for an intelligent toy, particularly a multi-channel speech controller for the toy. The utility model comprises a power amplifier output end (1) of a speech source and loudspeakers (3). The utility model is characterized in that the power amplifier output end (1) of the speech source is connected in parallel with two or more than two loudspeakers, one relay (2) is connected in series between the power amplifier output end of the speech source and each loudspeaker, and the relay is controlled by a drive circuit (4). The relay is used as an on-off switch between the power amplifier output end of the speech source and the loudspeakers. The utility model can control a speech signal output by the speech source to be converted into a sound signal by any loudspeaker, and simultaneously, the utility model does not influence the normal operation of the speech source and the loudspeakers.
Description
Technical field
The utility model relates to a kind of phonetic controller of intelligent toy.
Background technology
Speech source as herein described is meant and can produces the voice telecommunication of frequency in 20Hz～20KHz scope number, it can be the voice telecommunication number of cassette tape recorder, it also can be speech chip, or be stored in the storer (comprising ROM and RAM) digital speech electric signal through overcompression, through decompress and the reduction processing of circuit after voice telecommunication number.
The phonetic controller of the soniferous intelligent toy of existing energy is joined a loudspeaker by speech source and is realized sounding, and it can not realize a speech source on demand at a time by a loudspeaker sounding, and another is constantly by another one loudspeaker sounding.
Summary of the invention
The utility model has overcome the phonetic controller of existing intelligent toy and can not be have at random been converted the voice telecommunication of speech source output number the defective of voice signal to by any one loudspeaker, a kind of toy multi-path voice control device is provided, the voice telecommunication of this phonetic controller may command speech source output number is converted to voice signal by any one loudspeaker, does not influence the operate as normal of speech source and loudspeaker simultaneously again.
The utility model is achieved in that a kind of toy multi-path voice control device, comprise speech source power amplifier output terminal and loudspeaker, it is characterized in that speech source power amplifier output terminal and di-or two are with upper speaker, the relay of connecting between speech source power amplifier output terminal and each loudspeaker, relay is controlled by driving circuit, and relay is made the on-off switch between speech source power amplifier output terminal and loudspeaker.
Above-mentioned toy is with in the multi-path voice control device, and described driving circuit comprises single-chip microcomputer and ic chip, and single-chip microcomputer output connects ic chip, and the electrical equipment magnetizing coil is succeeded in ic chip output.
Principle of work of the present utility model is to be connected in series the on-off switch of relay as loudspeaker between speech source and loudspeaker.The magnetizing coil of driving circuit pilot relay, and then the adhesive of pilot relay, thus being connected or disconnection of control loudspeaker and speech source power amplifier output terminal makes the voice signal of speech source output be converted to voice signal for any one loudspeaker.Because the conduction impedance very little (usually less than 0.1 ohm) of relay switch, and the dc impedance standard value of loudspeaker is 8 ohm, so relay is sealed between speech source power amplifier output terminal and the loudspeaker, the normal sounding that can guarantee loudspeaker is unaffected, can realize the break-make between loudspeaker and speech source power amplifier output terminal again on demand, and not influence the impedance matching between loudspeaker and the speech source.The driving circuit pilot relay makes its on-off, can make some relay conductings and other relays are disconnected, thereby guarantee to have only the loudspeaker that is connected with this relay to be connected with speech source power amplifier output terminal, and other loudspeakers disconnect with it, thereby the different phonetic section in the realization speech source is by corresponding loudspeaker sounding, and don't influences the operate as normal of loudspeaker and speech source.
Description of drawings
Fig. 1 is the utility model toy multi-path voice control device block diagram, and Fig. 2 is a toy multi-path voice control device circuit diagram.
Among the figure: 1 speech source power amplifier output terminal, 2 relays, 3 loudspeakers, 4 driving circuits, 5 single-chip microcomputers, 6 ic chips.
Embodiment
Referring to Fig. 1, Fig. 2, toy adopts DC relay with the relay in the multi-path voice control device 2, as single-pole single-throw switch (SPST) relay 946H-1C-9D, 1 pin of this relay 2 and 3 pin, 4 pin are the normal-closed end of this relay 2 at inner Join together, 6 pin are Chang Kaiduan, and 2 pin and 5 pin are two ends of magnetizing coil.Single-chip microcomputer 5 is selected 4 above single-chip microcomputers for use, its required program storage can be built-in also can be plug-in, such as the AT89c51 that atmel company produces, built-in 4Kflash ROM; Ic chip 6 is selected high voltage, big electric current darlington transistor array device for use, such as ULN2803A.The I/O port of AT89c51, be connected with the 1B～3B of the input end of ULN2803A is corresponding one by one respectively as the P0.0～P0.2 of P0 mouth, output terminal 1C～3C of ULN2803A connects mutually with the magnetizing coil input end (i.e. 2 pin) of the 1st～No. 3 relay 2 is corresponding one by one respectively, and the output terminal of corresponding relay 2 magnetizing coils (i.e. 5 pin) all connects fixed level, as+10V.4 pin of relay 2 connect the A end of speech source power amplifier output terminal 1, and 6 pin of this relay 2 are the A end that Chang Kaiduan connects corresponding loudspeaker.The B end of all loudspeakers B end all direct and speech source power amplifier output terminal links.
If being AT89c51, single-chip microcomputer 5 gives P0 mouth output 01H, be P0.0=1, and other pin to be P0.1～P0.7 be all 0, then the 1B pin of ULN2803A is a high level just, and other input pins are low level, thereby make the delivery outlet of ULN2803A have only the 1C end to be all high level for low level 2C～8C.This is just in the pulse step of the magnetizing coil two ends of No. 1 relay 2 generation+9V, (when the ULN2803A saturation conduction, can produce the saturated tube voltage drop about 1V), thereby make No. 1 relay 2 produce the adhesive action, make the contact of No. 1 relay 2 jump to Chang Kaiduan from normal-closed end, thereby make 4 pin and the 6 pin UNICOMs of this relay, and then the A end that makes speech source power amplifier output terminal 1 only links with the A end of No. 1 loudspeaker 3, and disconnect with other loudspeakers 3, thereby make speech source 1 and don't influence the operate as normal of speech source 1, thereby reach the purpose of controlling the speech source sounding by No. 1 loudspeaker 3 sounding.If make speech source pass through other loudspeaker sounding, get final product then for the corresponding output of P0 mouth.
