Problems solved by technology

[0002] Ball games account for a large proportion of sports, such as basketball, volleyball, football, etc. Because various ball games are interesting and exercise, they have been loved by people all over the world. This type of inflatable hollow ball is because of the hollow inside It is full of air, light in weight, and has good elasticity. However, during the use of these balls, the ball collides with the ground or the human body to generate noise. The noise includes the noise generated by the impact of the ball with the outside world. The air compression and resonance noise generated affect people's use and viewing

Abstract

The invention relates to the field of sports appliances, in particular to a noise reduction inflatable hollow ball. The invention aims at providing the noise reduction inflatable hollow ball which comprises a hollow ball body and an inflating hole, wherein a noise reduction layer is arranged on the inner wall of the ball body; a recessed part is formed on the surface, towards the inner wall of theball body, of the noise reduction layer; the noise reduction layer and the inner wall of the ball body are fixed in a mode of using a plurality of parts in uniform contact; the elasticity of the ballbody is not influenced; meanwhile, the noise reduction area of the noise reduction layer is increased; the spreading of the noise can be blocked through a recessed cavity; a recessed part is also formed in the surface, towards the ball center, of the noise reduction layer; the area of the noise reduction layer is further increased; and small bulges are also arranged on the outer surface of the ball body.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a noise-reducing inflatable hollow ball. Background technique [0002] Ball games account for a large proportion of sports, such as basketball, volleyball, football, etc. Because various ball games are interesting and exercise, they have been loved by people all over the world. This kind of inflatable hollow ball is because of the hollow inside It is full of air, light in weight, and has good elasticity. However, during the use of these balls, the ball collides with the ground or the human body to generate noise. The noise includes the noise generated by the impact of the ball with the outside world. The air compression and resonance noise generated affect people's use and viewing. Contents of the invention [0003] The purpose of the present invention is to provide a noise-reducing inflatable hollow sphere, which includes a hollow sphere and an air-filled hole. A noise-reducin...
