Prior Art As shown in Fig. 1, the sounding ball 1 has a sounding circuit unit embedded near the surface of a gas-filled ball such as a soccer ball, dodgeball, volleyball, etc.
It has a structure in which this is covered with a lid member 2. 3 is a sound emitting hole formed approximately in the center of the lid member 2. For the sounding ball 1 having such a structure, a structure has been proposed in which the lid member 2 is adhered to the sounding circuit unit and the two are housed and fixed together in a recess provided on the ball surface. That is, the lid member 2 made of a cushion member is adhered to the top surface of the piezoelectric speaker of the sound generation circuit unit with an adhesive, and the substrate portion of the sound generation circuit unit is fixed to the storage case on the ball body side with screws or the like. Normally, with this type of ball 1, instantaneous impact force is repeatedly applied during kicking, bouncing, etc., so the adhesive force alone is insufficient, and the lid member 2 may peel off or fall off. There is. Since the purpose of the lid member 2 is to protect the sound generation circuit unit from external impact by its impact action, this problem is fatal to the product.

Embodiment FIGS. 2 and 3 show an embodiment of the present invention,
2 is the aforementioned lid member, which includes a sound emitting hole 3, a screw hole 4,
It has 4. This lid member 2 has a soft region 5 in the portion facing the ball surface, and a hard region 8 in the portion facing the sound generating circuit unit 6 and a mounting portion for a screw 7 serving as a fixing means. Here, the soft region 5 is made of soft rubber or soft plastic. The hard region 8 is made of hard plastic or hard rubber, and has a shape that covers the upper surface of the sound generating circuit unit 6, specifically, the piezoelectric speaker 9. Reference numeral 10 denotes a groove formed in the side wall of the hard region 8, and a protrusion 11 formed in the soft region 5 engages with this groove 10. in this case,
A hard region 8 and a soft region 5 are each prepared separately, an adhesive is applied to at least one of the contact surfaces of both regions 5 and 8, and the hard region 8 is pushed into the soft region 5,
The protrusions 11 are engaged with the grooves 10 and simultaneously bonded with an adhesive. Reference numeral 6 designates the aforementioned sound generation circuit unit, in which the piezoelectric speaker 9 is fixed to the upper surface of the substrate 12, and the shock sensor 13, the integrated sound signal generation circuit 14, and the battery case 15 containing the battery are fixed to the lower surface of the substrate 12. There is. This sound generation circuit unit 6 is assembled into a storage case 1 made of plastic or light metal by means of screws 7, 7 on the board 12.
It is fixed at 6. During this screwing, the lid member 2 is simultaneously fixed to the substrate 12 in its hard region 8. Inside the storage case 16, a stepped portion 17 is formed approximately in the middle thereof, with which the periphery of the substrate 12 comes into contact, and the stepped portion 17 in the portion where the screw holes 18, 18 are bored is formed wide. The position of this stepped portion 17 is set so that the surface of the lid member 2 coincides with the surface of the ball body 1 when the sound generation circuit unit 6 is stored in the storage case 16. 19
is a rubber tube 20 constituting the ball body 1;
2 is a thread-wound reinforcing layer, 21 is a rubber middle layer, and 22 is a skin layer. Reference numeral 23 denotes a flange formed around the end of the storage case 16, which is engaged and fixed in a groove 25 formed in the case storage part 24 integrally formed with the rubber tube 19 or bonded. The rubber tube 19 and the case storage part 24 are made of butyl rubber, which has high airtightness and high elasticity, but because of its high elasticity, it is easily deformed, and even when the storage case 16 is stored in the storage part 24, a strong impact force can be applied to the ball. There is a risk of it falling off when it joins. Said flange 23 and groove 25
This prevents this and strengthens the fixation of the storage case 16 to the ball.

FIG. 4 shows a modification of the embodiment of the present invention, in which a concave groove 26 of the hard region 8 is formed above the piezoelectric speaker 9, and a protrusion 27 of the soft region 5 is engaged with this. . In this way, the groove 26 and the protrusion 2
Since the engaging portion 7 is located above the piezoelectric speaker 9, the diameters of the lid member 2 and the sound generating circuit unit 6 can be set small. In the case of such a structure, the hard region 8 and the soft region 5 are similar to the above-mentioned example.
are connected by engagement or fusion. In the case of fusion bonding, it is desirable that the materials constituting both regions 8 and 5 have the same or similar solubility parameters. These two materials are
This is because if one is brought into contact with the other in a molten or softened state, the two will easily adhere to each other.
