Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a ball toy that produces sound.

(Prior Art) Conventionally, there are various types of ball toys that generate sound when subjected to vibration or impact, but usually they are simple sounds.

(Problems to be Solved by the Invention) As mentioned above, if the sounds are simple, children may find it too simple to play, and feel it is lacking.

An object of the present invention is to generate various sounds while playing with a ball, thereby making the game more interesting.

[Structure of the invention]

(Means for Solving the Problems) A ball toy of the present invention includes a spherical main body 1 and a sounding device 7 provided within the main body 1,
The sound generating device 7 includes a plurality of fixed contacts 16 arranged in an annular manner and a movable contact 18 attached to a flexible conductive support rod 17 provided in the center between the fixed contacts 16. There is a vibration switch 15 in which the movable contact 18 contacts or separates from one of the fixed contacts 16 due to vibration, and as the vibration switch 15 operates, it is determined which fixed contact 16 the movable contact 18 has contacted. a logic circuit 23 that outputs a signal corresponding to the fixed contact 16; a voice synthesis circuit 28 that is activated by the signal from the logic circuit 23 and outputs mutually different sounds corresponding to each of the fixed contacts 16; It is equipped with a speaker 30 connected to a voice synthesis circuit 28.

(Function) In the present invention, when the main body 1 of the ball toy is thrown like a catch ball or against a wall or the floor, and the impact causes the vibration switch 15 to vibrate above a certain level, the movable contact that acts as a weight 18 moves in any direction while bending the support rod 17 and comes into contact with one of the fixed contacts 16.

As a result, the power supply circuit of the randomly selected fixed contact 16 is turned on, and a signal output indicating the fixed contact 16 enters the logic circuit 23 as a trigger. A signal corresponding to the fixed contact 16 is applied to the voice synthesis circuit 28, and the sound formed by the voice synthesis circuit 28 is output from the speaker 30. As the movable contact 18 sequentially contacts each fixed contact 16, each fixed contact 16 produces a different sound.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a spherical main body, and this main body 1 has a pair of hemispherical core members 2 formed in half made of a non-elastic material such as foamed synthetic resin, which are joined together. An inner chamber 3 is formed therein, and a plurality of openings 4 communicating with the inner chamber 3 are formed at the joints of the pair of shell members 2, and a cloth is formed on the outer surface of the pair of shell members 2. etc. skin material 5
is attached.

A sounding device 7 is provided within the interior chamber 3 of the main body 1. This sounding device 7 has a printed wiring board 8
A case 9 made of insulating synthetic resin is attached on top of the printed wiring board 8 by means of a partition wall 10 integrally provided within the case 9, with a cylindrical switch chamber 11 in the center and a cylindrical switch chamber 11 on both sides of the switch chamber 11. A battery compartment 12, a switch compartment 11, and both wiring compartments 13 sandwiching the battery compartment 12 are formed into sections.

Then, a vibration switch 1 is installed in the switch chamber 11.
5 is provided. This vibration switch 15 is
A plurality of fixed contacts 16, four in this embodiment, are arranged in an annular shape along the inner wall surface of the switch chamber 11, and the base end of each fixed contact 16 is connected to the printed wiring board 8 by soldering. At the same time, the tip portion 16a of each fixed contact 16 is caulked to the outer surface of the case 9. In addition, each of the above fixed contacts 1
A support rod 17 whose base end is connected to the printed wiring board 8 is erected at the center of the space between the support rods 1 and 6.
A movable contact 18 is attached to the tip of 7.
The support rod 17 is made of a flexible conductive material such as a coil spring, and is normally upright, easily bent by impact force, and has self-righting properties. The support rod 17 itself acts as a weight to bend the support rod 17, so that it can come into contact with or separate from one of the fixed contacts 16.

In each of the battery chambers 12, a pair of electrode plates 20 are installed facing each other, and the base ends of the pair of electrode plates 20 are connected to the printed wiring board 8 by soldering, and the tips of each electrode plate 20 are connected to the printed wiring board 8 by soldering. The portion 20a is caulked to the outer surface of the case 9. A button-shaped battery 21 such as a mercury battery is installed between each pair of electrode plates 20.

Printed wiring board 8 in each wiring room 13 above
On the top are each fixed contact 16 of the vibration switch 15.
A support rod 17 and a battery 21 are connected to the movable contact 18 and the movable contact 18.
Components of the logic circuit 23 connected via
That is, resistor 24, capacitor 25, coil 2
6, a transistor 27, etc. are provided. The logic circuit 23 is connected to the vibration switch 15.
As the movable contact 18 contacts the fixed contact 16, it is determined which fixed contact 16 the movable contact 18 is in contact with.
A signal corresponding to the output signal is output with a predetermined time constant.

Further, an IC 29 constituting a speech synthesis circuit 28 connected to the logic circuit 23 is attached to the back surface of the printed wiring board 8. The voice synthesis circuit 28 is activated by a signal from the logic circuit 23, and outputs different sounds corresponding to each of the fixed contacts 16, respectively.

A flat speaker 3 connected to the IC 29 inside one or more openings 4 of the main body 1
0 is installed.

Then, when the main body 1 of the ball toy is thrown like a catch ball or against a wall or floor, and the impact causes the vibration switch 15 to vibrate beyond a certain level, the movable contact 18 acting as a weight will be supported. It moves in any direction while bending the rod 17, and comes into contact with any of the fixed contacts 16.

As a result, the power supply circuit of the randomly selected fixed contact 16 is turned on, and a signal output indicating the fixed contact 16 enters the logic circuit 23 as a trigger, and in this logic circuit 23, the signal output from which fixed contact 16 is determined. A signal corresponding to the fixed contact 16 is applied to the voice synthesis circuit 28 at a predetermined time constant, and the sound formed by the voice synthesis circuit 28 is output from the speaker 30. As the movable contact 18 sequentially contacts each fixed contact 16, each fixed contact 16 produces a different sound.

In this way, when a predetermined impact is applied to the main body 1 by throwing this ball toy like a catch ball or hitting it against a wall, etc., the vibration switch 15 is immediately actuated by this impact, and it emits various different sounds. Therefore, ball games can be played more interestingly.

Furthermore, by using the multi-contact vibration switch 15, the sound selection mechanism is mechanically performed at random, and the circuit configuration is simplified.

In addition, in implementation, the number of fixed contacts 16 of the vibration switch 15, that is, the type of sound, can be set as appropriate, and the number of fixed contacts 16 of the vibration switch 15 can be set as appropriate.
By appropriately selecting the deflection, etc. of 7, the pronunciation situation can be freely set.

The sounds produced by the speech synthesis circuit 28 include mutually different ranges, melodies, human voices,
Various sounds such as animal sounds can be selected.

〔Effect of the invention〕

According to the present invention, when a predetermined impact is applied to the main body of the ball toy by throwing it like a catch ball or hitting it against a wall, the vibration switch is immediately actuated by this impact and produces various different sounds. Therefore, ball games can be played more interestingly.
