The case 28 is built in the spherical core 29, and the spherical core 29 is covered with the shell 30, so that the case 28 does not rotate and is the same as the rotation of the spherical core 29. Even if it rolls and emits light, its movement is monotonous, so there is a problem that it is not interesting.

  The present invention was developed to solve the above-mentioned problems. When an external force is applied, the inner sphere containing the light-emitting device freely rotates in the water of the outer sphere, and is interesting. It is an object of the present invention to provide an LED-embedded water-filled elastic ball that can be played while enjoying a visual change due to a change in color of light emission or a change in light and darkness.

  As a means for solving the above-mentioned problems and achieving the object, the present invention comprises an inner sphere containing a light emitting device and a hollow outer sphere having a transparent or translucent elasticity, and is formed in the hollow portion of the hollow outer sphere. An LED-embedded water-filled elastic ball characterized in that it is filled with water and the inner sphere is floating in the hollow portion of the hollow outer sphere has been developed and adopted.

  In the LED-embedded water-filled elastic ball configured as described above, the light-emitting device includes a vibration sensor, a plurality of LEDs having different colors, a battery, a control circuit that emits light for a certain period of time, and a circuit board. The water-filled elastic ball with built-in LED, which is supported by a support piece on the inner wall surface of the inner sphere, and the inner sphere have a display surface for characters, symbols, patterns, characters, etc. on the outer surface A water-filled elastic ball with built-in LED was developed and adopted.

  In the water-filled elastic ball with built-in LED of the present invention, since the inner sphere with the built-in light emitting device floats in the water inside the outer sphere, when the external force is applied, the inner sphere rotates and the LED blinks freely. Rotating makes it brighter or darker, and you can play while enjoying beautiful visual changes. In addition, since the inner sphere is viewed through water, it appears to be approximately 150% larger than the actual size due to the lens action, and the LED blinks also appear to be larger, and the display surface of the character provided on the inner sphere is large and clear. It looks clear and the display effect is improved. Furthermore, even if the elastic ball is thrown on the floor or wall, the inner sphere is floating in the water, so the water acts as a buffer and the inner sphere does not directly contact the floor or wall. There is no risk of damage to the light emitting device, and it can be used for a long period of time.
