Description

[Detailed description of the invention]

<Industrial Application Field> The present invention relates to a ball having a gas-tight structure, and particularly to a sounding ball that is most suitable as a play ball for young children. <Conventional technology> Conventionally, as a ball equipped with a sounding function, for example,
Structures disclosed in Japanese Patent Publication No. 40-3081 or Japanese Patent Publication No. 43-23401 are known. In the former, a sound generator is placed at the center of a ball made of polystyrene foam, and is driven by a switch provided on the ball's surface. In the latter, a receiving device and a sound generating device are built into the ball, and a sound is generated from the sound generating device by operating the transmitting device from the outside. <Problems to be solved by the invention> Regarding the ball having the above structure,
A sounding device inside the ball is driven by the operation of a manual switch provided on the ball or by a signal sent from an external transmitting device, and the sound is generated continuously regardless of the movement of the ball, or by the operator of the transmitting device. The pronunciation is turned on and off according to the will of the person. That is, since the sound is not generated in response to an external force applied to the ball, such as kicking the ball, bouncing on the ground, etc., the sound is produced in a monotonous manner that merely informs the user of the position of the ball. In addition, when performing lifting exercises with a soccer ball (an exercise in which the user holds the soccer ball by applying it to the top of the foot, knee, chest, forehead, etc., without dropping the soccer ball to the ground), the ball may touch a part of the body. If a short sound is generated each time the ball hits the ball, the lifting movement can be made more interesting.In particular, such a structure is thought to make the game more enjoyable as the sound is generated by the bouncing pieces even when playing Temari for young children. . The present invention has been made with attention to such points, and each time an external force is applied to the ball, a sound is generated, and when the number of external force applications reaches a specific value,
The purpose is to realize a sounding ball that can generate a different type of sound than previous sounds. The present invention is further capable of detecting when the time interval between two successive external forces applied to the ball is abnormally short or abnormally long, and notifying this with a type of sound different from the normal sounding operation. Another purpose is to realize a pronunciation ball that can be used. <Means for Solving the Problems> In order to achieve the above-mentioned object, the following configuration is adopted in the present invention. That is, as shown in FIG. 2, there is a ball 2 having an air-receiving sealed tube filled with compressed air via an air injection valve 1 and imparted with rebound resilience as a ball; In the sounding ball, the sounding ball includes a sounding unit 3 embedded in a position opposite to the tube while maintaining an air-tight state of the tube.

The size and shape can be similar to gas-filled balls for ball games such as soccer balls and dodge balls. Reference numeral 4 denotes a buffer member provided on the surface of the sound generating unit 3, in which a sound emitting hole 5 is formed. The weight of the sounding unit 3 mounting portion and the weight of the valve 1 portion are set to be approximately equal, so that the center of the ball and the center of gravity coincide. Specifically, pronunciation unit 3 is
Through the use of small elements such as LSI and piezoelectric speakers, the overall weight of this part is approximately 20
It can be kept to about 30g or about 30g. On the other hand, since the weight of the valve 1 is usually about 8 g,
A balancer (not shown) weighing about 12g to 22g is added. Usually, children's play balls, such as children's dotsballs, weigh between 200g and 380g.
A soccer ball for children weighs about 300g or more.
Since the ball weighs 320 g, the total weight of the three sounding units and the balancer unit is approximately 1/5 to 1/10 of the weight of the ball, and has no substantial effect on the ball's movement. FIG. 5 shows the state in which the sound generating unit 3 is attached to the ball 2 and its structure. In the figure, reference numeral 6 denotes a rubber housing unit integrally formed with the tube 7 of the ball 2, and is made of the same rubber material as the tube 6, such as butyl rubber, and is shaped like a pot.

is a contact point located below the switch body 25, and is connected to the switch body 2 through a hole 28 provided in the skin 16.
It is closed by pushing down 5. This switch functions as a reset switch, which will be described later. A battery 29 is in contact with the back surface of the substrate 21, and is in contact with the contact pieces 30, 30. This battery 29 is housed in the unit case 14 via a screw cap 31. FIG. 6 is a surface view of the ball showing the sounding unit 3. The sounding unit skin 16 has the aforementioned small holes 17, 17, . . . and a switch hole 28 formed therein. Numerals 32 and 32 are holes into which a jig (crab-shaped) for screwing the sound generating unit 3 into the storage case 8 is inserted. FIG. 7 shows a processing circuit diagram of an external force detection signal,
33 is a well-known microcomputer, which basically consists of a CPU 34, ROM 35, and RAM 36. A program to control the CPU 34 is written in the ROM 36.
According to this program, the external force detection signal is taken in from the I/0 port 37, or the RAM
It performs arithmetic processing while exchanging data with 36, and outputs the processed data to I/0 port 37 as necessary. OSC38 is an oscillator, AB and
DB is CPU34, ROM35, RAM respectively.
36 and the I/O port 37. 20 is
In the aforementioned impact sensor, its detection signal is input to the I/0 port 37 via the DC voltage removal capacitor 39 and the waveform shaping circuit 40. 41 is a reset switch which, when closed, outputs a predetermined voltage signal to I/O.
0 port 37. 19 is the aforementioned piezoelectric speaker, 42 is a booster coil, and 43 is a transistor, which are driven by the sound generation signal output from the I/0 port 37. Next, the program written in the ROM 35 will be explained using the flowchart shown in FIG. When the program starts, the gates are locked (step) so that the program will not be executed unless a reset signal, which will be described later, is input. When a reset signal is input by operating the reset switch 41, counting is performed for 20 msec, and then the presence or absence of a reset signal is determined again. Such processing prevents chattering.
Incidentally, the above-mentioned reset signal is a signal for initializing the circuit system, but it also means a start signal. If the step determines that a reset signal is present, a start sound is emitted. The counters are then reset and unlocked at the same time. When an impact is detected by the impact sensor 21 and an impact signal is input, time counting starts, and with the subsequent input of the impact signal, the time counting ends, the counted time is memorized, the time counter is reset, and then the time counter is reset again. Time counting begins. The time t counted by the time counter until the successive second shock signals arrive is a preset time.
If it is determined that the time is equal to or higher than Tmax, a notification sound indicating that the time has expired is emitted. After passing through the steps, if it is determined that the counted time t is less than the set time Tmax and more than the preset time Tmin, the time memory is reset and the number of times counting process is executed. The number of times n increases by "1". If it is determined in step <<> that the counting time t is smaller than the time Tmin, a time shot notification sound is emitted. It is determined whether or not the value of the count content n has reached a predetermined value 9, which is set in advance. Each time the count increases, that is, each time the number changes from 1 to 9, a predetermined frequency is selected and a notification sound is emitted. When the count reaches n=10, the selected frequency changes and a different notification sound than the previous one is generated. In the same way, when n≧20, a sound with a different frequency is emitted. Until n rises to 90,
The sound changes every 10 pieces. Further, when the generation of the time over notification sound and the generation of the time short notification sound are executed, the circuit returns to the original initial state, and the circuit system is locked and enters a reset signal input standby state (locked state). In the above program, the notification sounds in Start notification sound generation, Time over notification sound generation, Time short notification sound generation, Frequency setting circuit, and Notification sound generation are frequencies, respectively. The time of occurrence etc. differs depending on the type, so you can know what it means by the sound. The table below is an example of each notification sound.
