What is ball that vibrates?

A ball that vibrates refers to a spherical object that has an internal vibrating mechanism designed to create smooth or erratic pulses that enhance the tactile experience. The ball vibration makes the user feel more sensations when handling it with their hands or other parts of their body. Such balls are widely used in various fitness and therapy activities, including massage, stress relief, strengthening, and rehabilitation exercises. The size, weight, and shape of the ball vary, depending on the intended use, and the vibrating intensity can be adjusted to suit the user's preference. The ball can also come with additional features such as textured surfaces or heat options to enhance its functionality.
