Description

The present invention relates to a toy responding to the voice in

which an oscillating piece is

activated by a voice input.

  Classically, toys are known in the

  which an electric motor is implemented by receiving a voice or acoustic signal transmitted from the outside to allow a moving part to move in different ways through a rotating mechanism and an oscillating mechanism, etc. Recently appeared a toy in which a rod,

  flowers, leaves or artificial flower

  sky are set in twisting motion by the entrance

a voice or a sound signal.

  The aforementioned conventional toy, reproducing an artificial flower and responding to the voice, in which a rod is placed in the center of the stem of the flower and an electric motor is implemented by the processing of a signal coming from a device. voice input (microphone) for rotating this rod through a series of reduction gears, has a simple and uninteresting movement, since the flower stalk, flowers, leaves or the like receive a torsion movement by undulating the rod in its longitudinal direction. Moreover, it happens that the microphone of this toy perceives the mechanical noise produced by the gear mechanism while

  the operation. As a result, when the switching

  is left in the "on" position, the battery pack wears out quickly, as the motor runs continuously, even if no voice or sound

are not injected at the entrance.

  An object of the present invention is to provide

  to create a voice-enhancing toy, improved by separately using a rotating rod and an oscillating piece,

  allowing a more interesting movement.

  Another object of the present invention is to

  to provide a voice-enhancing, improved toy that prevents

  singing a mechanical noise coming from the means of training

  engine, unless a voice or sound is injected at the entrance.

  To meet the above aims, the pre-

  This invention has the feature that a rotating rod is connected to the oscillating part via a damper. More specifically, in the present invention, the voice-responding toy comprises a housing, a rod placed on one side of the housing, an oscillating piece disposed on the other side of the housing and mounted on a damper, a damper connecting the rod to the oscillating piece, a microphone

  placed inside the housing, means of entral-

  to rotate the stem according to a voice signal at the input of the microphone and actuate the oscillating piece mounted on the damper, and a control circuit. The drive means comprise an electric motor, a belt type double reduction transmission mechanism, a ring gear placed at the end of the double transmission mechanism.

  reduction, and a coupling placed inside the cou-

  toothed ring, with which the lower end of the

  stem is engaged. In addition, the control means com-

  take a wave generator circuit for the sound input signal of the microphone, an amplifier circuit,

  and a charging and discharging circuit charged simultaneously

  by entering a voice signal and stopping the

  voice input signal by discharge.

  In the above toy responding to the voice, when a sound input signal is processed in the

  control circuit for driving the training means

  The rod located on one side of the housing rotates to oscillate the oscillating piece connected thereto by the damper. By a charge and discharge function in the control circuit, even if the voice input signal is present permanently, the electric current to the motor is temporarily interrupted for a time determined by a time constant of the charging circuit and of discharge, then a complex motion is transmitted to the oscillating piece by applying again

  the electric current after the discharge.

  The present invention will be described in

  detail, in conjunction with the accompanying drawings, in the

of the case.

  Figure 3 is an enlarged sectional view taken

  line III-III of Figure 2.

  FIG. 4 is a sectional view showing the manner in which the rod and the coupler are connected, and

  Figure 5 shows a control circuit.

  In FIG. 1, a housing 10 comprises an upper half-portion 10a and a lower half-portion 10b, a housing 11 containing a stack, a control portion 12, a box 13 for the drive means

  and the switch 14. A rod 15 and an oscillating member

  lante 16 are respectively fixed on each side of the upper half-portion O10a. The oscillating piece 16 is

  used to imitate a musical instrument, a

  animal, or the like, and its upper half is

  connected to the rod 15 via the first shock absorber

  weaver 17, its lower half being supported elastically by the housing via the

second damper 18.

  A battery 20 is in the housing 11 of the battery. The control portion 12 is substantially constituted by a printed circuit 21 inserted into the fork portion projecting from the bottom surface of the lower half-portion 10b of the housing. A motor 22 is on one side of the box 13, and a microphone 24 is placed on the other side. The microphone 24 is placed just below an opening formed in the upper half-portion 10a of the housing

  to allow the entry of the voice.

  First and second horizontal shafts 26, 27 are disposed above the box 13, and it is

  in addition to a double-reduction transmission element

  belt type. Thus a first belt 30 connects a pulley 28 to the output shaft of the motor 22 to

  a pulley 29 on the end of the first horizontal shaft

  26, while a second belt 33 connects a

  lie 31 located in the box at a pulley 32 of the second

horizontal tree 27.

  As seen in Figure 3, at the other end of the horizontal shaft 27 is a pinion which meshes with a ring gear 37, resulting in

  a vertical shaft 36 in the box. At the upper end

  the shaft 36 is secured to a coupler 38 of the internal gear type. The coupler 38 is inserted in a

  guide 39 protruding downward from the upper wall

  top of the box. As seen in FIG. 3, the coupler 38 is designed to receive a fixed gear 40

  on the lower part of the stem 15.

  The rod 15 is covered by a tube 42 provided with a retaining piece 41; as can be seen in FIG. 1, at its upper end there is a gripper portion 43 belonging to the oscillating piece 16 and mounted at the end of the first

shock absorber 17.

  After the switch 14 has been put in the "on" position, the voice signal is transmitted to the

  microphone 24 and processed by the control part (cir-

  control gear) 12 for driving the motor 22. The pinion 35 of which the second horizontal shaft 27 is provided is rotated by the motor, by means of a double reduction mechanism consisting of the belts and the pulleys, to make turn the rod 15 through the ring gear 37, the shaft 36,

  of the coupler 38 and the gear 40.

  As shown in Figure 1, the rod 15 is slightly curved upward from its root, so that, as indicated by the arrow, its upper portion is driven in a circular motion. This circular movement is transmitted to the oscillating piece 16 carried by the second damper 18, via the first damper 17, and causes an overall oscillating movement, combined with a slight

  vertical movement. While the rod 15 is

  belt-type reduction in order to eliminate noise, and mechanical noise originating in the transmission device

reach the microphone 24.

  Figure 5 shows an example of a control circuit. The signal transmitted by the microphone 24 is synthesized by a circuit comprising Qi transistors

  Q2 and Q3, and amplified by a transistor Q4 for power supply

the engine 22.

  While the motor 22 is energized, the electrical level of the point A, after the signal synthesis step, is applied to the diode D1, to the charging and discharging circuit C4, C1 ,, and charges the capacitor C4 at the moment o between a voice signal. By discharging after a time CR, the transistor Q5 is turned on to allow the terminal voltage on the resistor RB to cancel, so that the microphone is turned off, and as a result the power supply to the motor is momentarily cut off. When the transistor Q5 is not on, while the discharge ends, the voltage is applied to the resistor RB, and the signal that comes in through the microphone is synthesized and amplified to turn the motor again. By repeating the above, the rod is rotated intermittently, which gives a complex motion to the oscillating piece 16. As has been seen, the present invention provides a voice-responding toy in which a rod, vertically fixed on one side of the housing, rotates and is connected, via the damper, to the oscillating part carried by the other side of the housing, to

  which it transmits a movement which is a combination of

  of a circular movement and a green movement

  tical, so that the oscillating piece is animated with an interesting movement synchronized with a voice input

and sound.

  As claimed in claim 2, the microphone input signal is protected against

  disturbances by the presence of a reduction mechanism

  belt type in the drive means,

  which eliminates the mechanical noise. Moreover, as

  in claim 3, the charging circuit and the

  discharge is part of a control circuit that inter-

  automatically breaks the rotation of the motor, so that the movement of the oscillating piece becomes more

  complex, and that a saving in

electrical power.

  Of course, the invention is not limited to the embodiments that have just been described and can be made to these many modifications

  without departing from the scope of the invention.
