[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 6As shown, a noise-reducing pickle ball has a plurality of evenly spaced through holes 4 on the surface of the ball, and the through holes 4 penetrate the ball. The ball includes a PU layer 1, a hard layer 2, and a sound-absorbing layer 3. The inner wall of the PU layer 1 is provided with a hard layer 2, and the inner wall of the hard layer 2 is provided with a sound-absorbing layer 3. The material of the PU layer 1 is foamed PU. When playing pickle ball, the PU layer 1 is the outermost layer of the ball and is directly impacted, which can provide a buffering space, improve the elasticity of the ball, and reduce the sound of the ball hitting. The outer wall of the PU layer 1 is provided with a plurality of evenly spaced synapses 11, and the synapses 11 are integrated with the PU layer 1. The synapses 11 increase the friction between the ball and the racket, making it easier for athletes to use the racket to change the rotation state of the ball. The integrated synapses 11 have a greater bonding strength with the PU layer 1. The outer wall of the hard layer 2 is provided with a plurality of evenly spaced grooves 21, and the PU layer 1 is provided with an inner convex block matching the grooves 21. The cooperation between the groove 21 and the inner convex block increases the contact area between the PU layer 1 and the hard layer 2 , improves the bonding strength between the PU layer 1 and the groove 21 , and prevents the PU layer 1 and the hard layer 2 from loosening.

[0021] The hard layer 2 of the middle layer is generally made of hard plastic. The hard layer 2 is the main structure of the sphere and mainly plays the role of anti-deformation. The inner wall of the hard layer 2 is provided with integrated reinforcing ribs 22, and the reinforcing ribs 22 are evenly distributed on the inner wall of the hard layer 2. The reinforcing ribs 22 are crisscrossed on the inner wall of the hard layer 2, which effectively improves the anti-deformation ability of the hard layer 2 without increasing the thickness of the hard layer 2 too much.

[0022] When the ball moves, the airflow passes through the through hole 4 and makes a sound. The loose and porous sound-absorbing layer 3 in the inner layer of the ball can absorb the sound made by the airflow. The inner wall of the sound-absorbing layer 3 is provided with a plurality of sound-absorbing holes 31 with uniform intervals. The porous structure inside the sound-absorbing layer 3 further reduces the noise made by the ball.

[0023] The working principle of the specific embodiment of the utility model is as follows: when playing pickle ball, the outermost PU layer 1 of the ball is hit first, and the elasticity of the PU layer 1 has a certain buffering effect on the hit ball, reducing the sound of the impact. During the pickle ball movement, the sound emitted by the airflow passing through the through hole 4 is partially absorbed by the porous structure composed of the sound absorbing layer 3 and its sound absorbing holes 31, further reducing the noise emitted by the pickle ball.
