         5 . The spherical structure according to  claim 1 , wherein the sphere is a light-transmissive sphere and is made of elastic plastic. 
     
     
         6 . The spherical structure according to  claim 5 , wherein the sphere is made of a polypropylene material or a polyethylene material. 
     
     
         7 . The spherical structure according to  claim 2 , wherein the protruding strip and the protruding bumps thereon are made of an elastic rubber material. 
     
     
         8 . The spherical structure according to  claim 7 , wherein the protruding strip and the protruding bumps thereon are made of a thermoplastic rubber material. 
     
     
         9 . The spherical structure according to  claim 1 , wherein the sphere and the protruding bumps are made of a foaming material. 
     
     
         10 . The spherical structure according to  claim 1 , wherein a groove is correspondingly recessed in each of outer sides of any two opposite protruding bumps. 
     
     
         11 . The spherical structure according to  claim 10 , wherein the groove is an elongated and narrow groove. 
     
     
         12 . The spherical structure according to  claim 1 , wherein a ratio of a diameter of the sphere to a thickness from a top surface of each of the protruding bumps to the surface of the sphere is between 17.5:1 and 35:1. 
     
     
         13 . The spherical structure according to  claim 1 , wherein the interior of the sphere is hollow, and a counterweight is suspended inside the sphere. 
     
     
         14 . The spherical structure according to  claim 13 , wherein the counterweight includes an upper counterweight and a lower counterweight stacked in a top-down manner, and a weight of the lower counterweight is greater than a weight of the upper counterweight. 
     
     
         15 . The spherical structure according to  claim 13 , wherein the counterweight is a counterweight circuit board, and the counterweight circuit board includes a light-emitter, a power supply, and a main controller; wherein the main controller is in electrical connection with the light-emitter and the power supply, and the light-emitter includes at least one light-emitting diode. 
     
     
         16 . The spherical structure according to  claim 15 , wherein a shaking switch that is in electrical connection with the main controller is disposed on the counterweight circuit board, and the shaking switch is used to sense shaking; wherein, when the shaking switch senses a shaking, the light-emitting diodes are switched on, and when the shaking is not sensed after a preset period of time has elapsed, the light-emitting diodes are switched off.
