Abstract

The utility model relates to an acoustic control flocky singing duck toy which is composed of a mechanical driving mechanism and an acoustic control circuit. The utility model is characterized in that a motor and a reduction gear in a drive box are connected with a speed changer to actuate two eccentric gears on two working shafts to drive respectively. One eccentric gear drives a pendulum bar to swinging left-to-right or up and down, and namely, a duck head swings; the other eccentric gear drives a slide block to move up and down, so that the wings of the duck can wave. By the acoustic control circuit, the mechanical movement of the toy can be started up and send out sound at the same time. The toy has the advantages of bright color, novel and specific appearance, lively conformation, compact structure, ornament and interest.

Description

Acoustic control fine hair singing duck toy

The utility model relates to a kind of acoustic control fine hair singing duck toy.

The push toy that is loved by the people at present, though come in every shape, various in style, generally mostly be product static and that action is single, lack interesting and ornamental.

The purpose of this utility model just for the shortcoming that overcomes above-mentioned prior art with for not enough, and send the fine hair singing duck toy of song when adopting acoustic control that toy is moved, thereby make static toy have the dancing singing dynamic function of emulation shape.

The purpose of this utility model realizes by following technical proposal:

Acoustic control fine hair singing duck toy, comprise fore shell, back cover, the chassis, fine hair, mechanical transmission mechanism and sound control circuit are formed, it is characterized in that mechanical transmission mechanism is by transmission case, motor, gear train, working shaft, optical axis, eccentric wheel, slide block and fork are formed, transmission case (18) is fixed on the fore shell internal upper part, case inner motor (24) drives pinion (201) and is fixed on upward gear wheel (202) engagement of duplicate gear of optical axis (23A), its pinion (203) and gear wheel (204) engagement that is fixed on the last duplicate gear of working shaft (23), its pinion (205) meshes with the gear wheel (206) that is fixed on the last duplicate gear of optical axis (22) again, its pinion (207) meshes with the gear wheel (208) that is fixed on the last duplicate gear of working shaft (21) again, form the transmission train of reduction gears, the eccentric wheel (31) that is fixed on the working shaft (23) cooperates with slide block (29) centre bore, slide block two ends bossy body stretches into the housing wing root of duck toy, be fixed on working shaft (21) and upward fix a fork (32) on the eccentric wheel (28), the fork top is a spherical frame shape, stretches in the housing duck head.

Sound control circuit is by electric capacity miaow MC, the coupling amplifying circuit, the language integrated circuit, loudspeaker (6), switch (9), motor and power supply are formed, power supply is three joint No.5 cell 4.5V voltages, is contained in the battery case (10), and battery case and chassis (11) are injection molded into one, the chassis is provided with the IC circuit board, IC language integrated circuit block is arranged and by Q on the circuit board ₁, Q ₂, Q ₃, Q ₄Form amplifying circuit, R ₁Be the operating resistance of electric capacity miaow, R ₂, R ₃, R ₃, form feedback circuit, R ₄, R ₅, R ₆, be the biasing resistor of Q2, Q3, R ₇Be the oscillation resistance of IC, C5 filter capacitor, Q ₃For motor starting amplifies, R ₈Be the shunt resistance of Q4, R ₉Be Q ₃Divider resistance, C ₄Be motor starting electric capacity, loudspeaker are fixed on the fore shell, and switch connects with lead, is fixed on the chassis.

Owing to take technique scheme to make the utility model compared with the prior art have following advantage and effect:

A) adopt the electric mechanical technology, make existing static push toy become dynamic toy.Increased the function of toy, and made it reach simulated effect.

B) carry out synchronously by acoustic control control toy duck body movement and sound equipment, and can arbitrarily repeat performance,

C) moulding fineness, its body movement is true to nature, and overall structure is tightly played, and has good sight and interest.

Below in conjunction with accompanying drawing embodiment the utility model technology is further specified:

Acoustic control fine hair singing duck toy, comprise fore shell (2), back cover (15), chassis (11), fine hair (1), mechanical transmission mechanism and sound control circuit are formed, the protecgulum of transmission case (18) screw (17,19) be fixed on the fore shell internal upper part, motor (24) drives pinion (201) and is fixed on upward gear wheel (202) engagement of duplicate gear of optical axis (23A), and pinion (203) and gear wheel (204) engagement that is fixed on the last duplicate gear of working shaft (23), its pinion (205) meshes with the gear wheel (206) that is fixed on the last duplicate gear of optical axis (22) again, its pinion (207) meshes with the gear wheel (208) that is fixed on the last duplicate gear of working shaft (21) again, form train of reduction gears, the eccentric wheel (31) that is fixed on the working shaft (23) cooperates with slide block (29) centre bore, slide block two ends bossy body stretches into duck toys shell wing (5) root, by connector (4) wing is agitated, the eccentric wheel (28) that is fixed on the working shaft (21) is fixedlyed connected with fork (32) bottom with screw (33), fork top spherical frame stretches in the housing duck head, swing back and forth up and down by fork, even the duck head does to swing action, gear train seals with transmission case bonnet (25), and back cover is connected as a single entity with screw (14) (16) and fore shell.

Sound control circuit is by electric capacity miaow MC, coupling amplifying circuit, language integrated circuit, loudspeaker (6), switch (9), motor and power supply are formed, and language surface-mounted integrated circuit IC (13) is fixed on the chassis with screw (12), and nut (26) bolt (27) is fixed on battery case lid (30) on the battery case (10), No. three batteries of five joints are housed in the box, screw (8) makes loudspeaker be connected with horn ring (7), and loudspeaker are fixed on the fore shell, and switch (9) is installed on the chassis, connect triode Q with lead ₁, Q ₂, Q ₃, Q ₄Form amplifying circuit, resistance R ₄, R ₅, R ₆Be Q ₂, Q ₃Biasing resistor, R7 is the IC oscillation resistance, C ₅Be filter capacitor, Q ₃Motor drives and amplifies R ₈Be Q ₄Shunt resistance, R ₉Be the divider resistance of Q3, C ₄Be motor starting electric capacity.

When sounding near the toy, when clapping one's hands the voice signal that sends, make MC electric capacity miaow receive voice signal, through C as using ₁Be coupled to Q ₁, and through after amplifying, by colelctor electrode output, at Q ₂Base stage on be added with base current, thereby make Q ₂Work after the emitter and collector conducting, triggers IC and makes Q ₄Work promotes loudspeaker and sends the sound that duck is sung, simultaneously Q ₂Through R ₅Give Q ₃One base current makes Q ₃Work, the emitter and collector conducting provides 4.5V voltage to motor, makes motor running, because Q ₃Base stage be connected sound control circuit Q ₂Colelctor electrode on, when audio signal increases, Q ₃The voltage of being exported also can increase thereupon, motor running is accelerated, otherwise, sound hour, motor rotary speed also slows down thereupon, thus the sound and the action that reach toy are consistent, pass through control circuit, promptly stop after a rhythm is finished in sound equipment and action, as giving a voice signal again, the duck of then singing remakes repetitive operation and sound equipment again and can arbitrarily control.
