Abstract
The utility model relates to a remotely controlled sound-producing device which can cause dolls like a person doll and an animal doll to speak and produce sound, comprising a receiving sound-producing device in the doll and a modulating transmitting device out of the doll. The modulating and transmitting device comprises a modulating unit modulating a sound source and a high frequency modulating and transmitting circuit modulating signals. The sound source comprises sound which is received by a microphone MIC or sound which is exported by a sound playing machine. The receiving sound-producing device comprises a frequency modulating, receiving circuit and a power amplifying circuit, a speaker producing sound and a light emitting diode which can indicate sound signals and is arranged in the mouth of the doll. The utility model has the characteristics of strong function and simple structure.
Description
The utility model relates to a kind of toy, doll, relates to a kind of device of specializing in doll remote control sounding or rather.
Raising along with the level of consumption, only can send personage, the animal doll of the dull sound, not looked at by the children parent, the meetings such as animal that people require the doll, personalize sing, sociable, can tell a story, particularly in large and medium-sized adventure playground, thisly can cause the great interest of children with the doll moulding meeting of child dialog, the emotion that can express thoughts.
Based on this development trend, Chinese patent CN92209694.5 " Talking toy baby " is exactly a kind of toy that the doll is spoken by remote control, comprises the A machine that places doll's body and places the interior B machine of the external certain distance scope of doll.In A, the B machine emission, receiving circuit and sound pick-up are arranged all, when utilizing the wireless talkback principle to realize that the emission of B machine, A machine receive sounding or the emission of A machine, B machine and receive the intercommunication mode of sounding and B office and close, the A machine is touched the mode of laughing of sending laugh.
This apparatus structure is complicated, and cost is higher, and practical value is low, does not meet the mass consumption requirement, thereby has influenced the enforcement of technology.
The purpose of this utility model is a kind of Doll with speaking function of design, promptly is suitable for various personages, animal-shaped remote control sound-producing device, and has simple in structure, practical characteristics.
Remote control sound-producing device of the present utility model, by placing the modified tone emitter in the external certain distance scope of doll and placing the receiving system in the doll body to form, emitter comprise to source of sound modify tone the modified tone circuit handled and to the transposer output audio signal amplify, the high frequency transmission circuit of high frequency modulated emission, the source of sound of emitter comprises the sound pick-up that is connected with the input of modified tone circuit and by installing (record) sound machine of putting that source of sound interface, source of sound connector are connected; Receive sound-producing device and comprise reception antenna, the high frequency receiving circuit that antenna receiving signal is carried out demodulation, the light indicating circuit of power amplification circuit that the high frequency receiving circuit output audio signal is amplified and loudspeaker thereof, voice signal.
Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing.
Accompanying drawing 1 is for placing the external remote-controlled launcher electrical schematic diagram of Doll with speaking function.
Accompanying drawing 2 is for placing the reception sound-producing device electrical schematic diagram in the Doll with speaking function body.
Referring to accompanying drawing 1, monolithic audio pitch shifting IC circuit 1 and peripheral circuit thereof constitute specific language modified tone circuit, increasing or decreasing K switch 1, K2, can freely select seven kinds of variation tone outputs such as this sound, male sound, women sound, sound sound, robot sound, the audio signal of IC1 the 12nd end output through modifying tone and handling is coupled to the amplifier of being made up of triode BG1 and peripheral cell thereof through C7 and cushions amplification.BG2, BG3 and peripheral cell thereof are formed modulating emission circuit, and wherein BG2, CW, C18, L1, C10 etc. form the modulating wave oscillator, and BG3, C13, L2 etc. form frequency-selective amplifier, will launch through the amplification of the signal after the modulation such as BG2 and by antenna TX1.
The input source of sound of monolithic frequency conversion modified tone IC circuit 1 comprises the sound pick-up MIC of its 8th, 9 end and (record) sound machine of putting that is connected by device COBBAIF JK, audio connector J1, J2, and the modified tone of this emitter launches that voice that MIC picks up or cassette player emit prerecords sound on tape.
With source of sound connector J1(J2) insert among the interface JK, sound pick-up MIC disconnects voluntarily, J2(J1) then inserts in the cassette player jack, the source of sound connector is the lead that connects two plug J1, J2, in the lead by the resistors match network of forming by R21, R22.
Referring to accompanying drawing 2, low pressure monolithic high frequency receiving circuit IC2 and peripheral circuit thereof are formed high frequency receiving circuit, and the high-frequency modulation signal of modified tone that antenna TX2 is received carries out demodulation, regulate CW1, can change receive frequency.C12, R2, BG1, BG2, LED1 etc. form the high frequency indicating circuit, receive the high-frequency modulation signal of emitter emission shown in Figure 1 as IC2 after, LED 1 is lighted, and is used to indicate accepting state.Potentiometer W is used for volume to be regulated.Integrated operatinoal amplifier IC3 and peripheral circuit thereof are formed power amplifier, through the modified tone audio signal promotion loudspeaker SP of IC3 power amplifier sounding.
BG3, LED2, R7 etc. form the light indicating circuit of voice signal, and LED 2 can glimmer along with the power of modified tone voice signal, speed, during enforcement, LED2 can be placed the doll mouth, and to strengthen effect, LED3 is a power supply indicator among the figure.
The utility model function is strong, simple in structure, and embodiment tranmitting frequency 90～100MHz can reliable remote control doll in 35 meters radius speaks, singing etc., can be used as children's daily toy, also can be used for the large-scale puppet of advertisement and public place of entertainment etc.
