The driving gear on the circumference of the cylinder,
and a driving means for rotating the cam barrel meshed through gears, and a swinging cam surface for swinging the swinging lever on the upper end surface of the cam barrel of the blowing mechanism, which is synchronized with the operation of the blowing mechanism. A swinging plate having an engagement plate fixed to the tip of a swinging arm having a crank portion for engaging the swinging cam surface is pivotally attached to the base, and the swinging plate is used to engage the swinging cam surface. By making the swinging lever swing, the bird senses sound and blows, and its beak and tail feathers swing in time with the sound, making it an interesting little bird that operates just like a real bird. It is in the provision of toys.

An embodiment of this invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a frame body that is molded in the shape of a bird's body from synthetic resin and can be divided into halves. This frame 1
A raised cloth or a long pile cloth 2 in which a large number of synthetic fibers are implanted is pasted on the surface of the feather, and feathers 3 made of the same material are pasted as necessary. This frame 1
Inside, a sound sensing mechanism 10 and a blowing mechanism 20 controlled by the sound sensing mechanism 10 are provided, as well as a swinging lever 6 to which a lower beak 4 is fixed at one end and a tail feather 5 is fixed at the other end. Its approximate center is pivotally mounted within the frame 1. A large number of openings 7 for passing sound are bored at appropriate intervals on both sides of the frame 1.

The sound sensing actuation mechanism 10, as shown in FIG.
The output end of the condenser microphone 11 is connected to the amplifier circuit 12.
The output terminal of this amplifier circuit ₁₂ is connected to the input terminal of a one-shot multivibrator 13, and the output terminal of this one-shot multivibrator 13 is connected to the input terminal of a power drive circuit 14. Consists of connections.

That is, resistors R ₁ , R ₂ , R ₃ and NPN type transistor
Microphone 1 is connected to the input terminal of amplifier circuit 12 consisting of Q ₁ .
Connect the output end of 1 through capacitor _C1 .
Next, the output terminal of the amplifier circuit 12 is connected to resistors R ₄ to _{R 9}
and NPN transistor Q ₂ and PNP transistor
It is connected to the input terminal of a one-shot multivibrator 13 consisting of _Q3 , electrolytic capacitor _C2 , and diode D.

The output end of this one-shot multivibrator 13 is connected to an NPN transistor _Q4 and a resistor.
It is connected to a power drive circuit 14 consisting of R ₁₀ and R ₁₁ . Incidentally, a motor 31 of a blowing mechanism 20, which will be described later, is connected to the power drive circuit 14 as a load. In the figure, C ₃ is a decoupling capacitor for the entire sound sensing and operating mechanism 10.

Therefore, when external sounds such as applause or human voices are applied,
A microphone 11 senses the sound, and an amplification circuit 12 amplifies the electrical signal of the sound. This amplified signal turns on the transistor _Q2 of the one-shot multivibrator 13. When transistor Q ₂ is turned on, the base current of transistor Q ₃ flows, turning transistor Q ₃ on. Then, the collector current of the transistor _Q3 flows to the base of the transistor _Q4 of the power drive circuit 14, and the transistor _Q4 is turned on. Therefore, the motor 31 of the blowing mechanism 20 is rotated.
At the same time, the collector current of transistor Q ₃ flows through the CR circuit consisting of resistors R ₇ , R ₈ and capacitor C ₂ until capacitor C ₂ is charged.
In order to conduct current to the base of Q ₂ , the transistor Q ₂
will continue to be in the ON state even if the amplified external sound signal is no longer available. Therefore, the transistor
Q ₃ and Q ₄ also continue to be in the ON state, and the motor 31 continues to rotate. Eventually, when the capacitor C ₂ completes charging, the base current stops flowing to the transistor Q ₂ , turning the transistor Q ₂ into an OFF state. This transition of the transistor Q ₂ to the OFF state also brings the other transistors Q ₃ and Q ₄ to the OFF state, and the motor 31 stops rotating.

Note that the sound sensing operating mechanism 10 is connected to the resistor R ₁ of the amplifier circuit 12, except when it is operating by sensing sound.
Since the current flows only through _R2, etc., and the current is very small, power consumption can be reduced.
Accordingly, since the dry cell battery 15 consumes little, there is no need for a power switch or the like, and the device can be used in a state where external sounds are constantly sensed.

The blowing mechanism 20 includes a whistle 21, levers 25 and 26 that drive the whistle 21, a cam cylinder 27 that swings the levers 25 and 26, and a driving means 30 that rotates the cam cylinder 27.

The flute 21 consists of a flute body 22, a bellows 23 for supplying air to the flute body 22, and a pitch adjusting piston 24 fitted inside the flute body 22.

The levers 25 and 26 include a blowing lever 25 and a pitch adjustment lever 26. The blowing lever 25 is for operating the bellows 23, and its central portion is attached to the base 28 so that one end is in contact with the bellows 23 and the other end is in contact with a bellows operating cam surface 27A formed on the circumferential surface of the cam cylinder 27. It consists of a pivot point. Further, the pitch adjustment lever 26 changes the pitch of the sound generated by the whistle 21 by reciprocating the piston 24 within the whistle body 22.
The center portion thereof is pivotally connected to the base 28 so that one end contacts the rear end surface of the piston 24 and the other end contacts the pitch adjustment cam surface 27B of the circumferential surface of the cam cylinder 27. In addition, a blowing lever 25 and a pitch adjustment lever 26 are installed inside the bellows 23 and the piston 24, respectively, and the cam surface 27A,
A coil spring 29 is provided for pressure contact with 27B.

The driving means 30 meshes a worm wheel 33 with a worm 32 fixed to a drive shaft of a motor 31, then meshes a small gear 34 coaxial with the worm wheel 33 with a driving wheel 35A of an intermediate gear 35, and further A driven wheel 35B of the gear 35 is meshed with a driving gear 27C formed on the circumferential surface of the cam cylinder 27.

Further, the upper end surface of the cam cylinder 27 is formed with a swing cam surface 27D for swinging the swing lever 6 pivotally mounted within the frame body 1. A swinging plate 38, which is formed by fixing an engagement plate 37 to the tip of a swinging arm 36 bent into a crank shape, is pivotally mounted on the base 28.
A crank portion 36A of the swing arm 36 is engaged with the swing cam surface 27D.

The cross-sectional shapes of the bellows operating cam surface 27A, pitch adjustment cam surface 27B, and rocking cam surface 27D are formed so as to be related to each other. For example, the pitch of the blowing sound may be gradually changed by forming the respective cam surfaces 27A and 27B so as to swing the pitch adjustment lever 26 while the blowing lever 25 is swinging, or the pitch of the blowing sound may be changed gradually. The cam surfaces 27A and 27B are formed so as to change the position of the piston 24 and the position of the piston 24 when the blowing lever 25 swings for the second time, so that the sounds generated at different pitches are alternately and intermittently sounded. It has been done.

Therefore, the blowing lever 25 and the pitch adjustment lever 26
By working in conjunction with this, a blowing sound that approximates the sound of a real bird can be obtained. In addition, the swing cam surface 27D is used for the operation of the blowing mechanism 20, that is, for each lever 25, 26.
It is formed so that it oscillates in synchronization with the oscillation of the.

When the blowing mechanism 20 is installed inside the frame 1, the engagement plate 37 of the swing plate 38 is attached to the swing lever 6.
This is done by arranging it so that it is engaged with the Furthermore, the frame 1 is fixed on a stand 8 in which a dry battery 15 for power supply is housed.

This idea is constructed as described above, and inside the frame 1,
Since the sound detection actuation mechanism 10 and the blowing mechanism 20 controlled by the sound detection actuation mechanism 10 are provided, it is possible to detect external sound and generate a blowing sound.

The sound detection actuation mechanism 10 includes a microphone 11 and an amplifier circuit 1
2, one-shot multivibrator 13, and power drive circuit 14 are connected to each other, the mechanical configuration can be simplified.

The blowing mechanism 20 is provided with a whistle 21 having a bellows 23 and a pitch adjusting piston 24, and has two levers 25, 26 which are independently swung by a cam cylinder 27 rotated by a motor 31. Since the bellows 23 and the pitch adjusting pistons 24 are connected to each other, the bellows 23 and the pitch adjusting pistons 24 work together to produce a blowing sound that approximates the sound of a real bird's cry.

A swinging lever 6 having a beak 4 fixed to one end and a tail feather 5 fixed to the other end is provided in the frame 1, with its approximate center pivoted, while a swinging cam surface 27D is mounted on the end face of the cam cylinder 27. A swinging plate 38 that engages with this swinging cam surface 27D is pivotally connected to the base 28, and the swinging lever 6 is swung by this swinging plate 38. The beak 4 and tail feathers 5 can be swung, allowing the bird to move as if it were a real bird.

Moreover, since the rocking cam surface 27D is formed to rock the rocking plate 38 in synchronization with the operation of the blowing mechanism 20, the beak 4 and tail feathers 5 can be rocked in synchronization with the blowing sound, making it even more realistic. This allows you to move like a bird.

Furthermore, a large number of openings 7 for sound communication are provided on both sides of the frame 1.
By arranging them at appropriate intervals, the blowing sound generated by the blowing mechanism 20 can be well transmitted to the outside of the frame 1. In addition, there is a stand 8 for storing 15 dry batteries.
By fixing the frame 1 on top, the overall stability can be achieved.

As explained above, according to this invention, external sounds are sensed and the song is blown, and the beak and tail feathers are swayed in time with the sound, making it possible to obtain an operation similar to that of a real bird chirping, which is very interesting. This is what we can provide with a variety of small bird toys.
