Common mechanical sounding toys for infants include rattles, bells, and the like. The main body of the rattle drum is a small drum, two sides of the drum are provided with two pills, a handle is arranged below the drum, and the pills rotate the drum handle to throw the drum to produce sound. The drum body can be made of wood or bamboo, or mud or hard paper; the drum surface is made of sheepskin, cowhide, snake skin or paper. The bullet can play a varied sound and attract the attention of infants, but the bullets on the two sides of the bullet are easily swallowed by the infants, thereby threatening the personal safety of the infants, and the production is rarely carried out at present.

The bell is a bell which sounds by shaking, and is spherical or round, the lower part or the middle part of the bell is provided with a mouth, and metal balls or small stones are placed in the bell, and the bell has different sizes. Most of the infants are suitable for hand bells or wrist bells. The outer shell is mostly plastic or metal. The sound may be emitted when shaken or shaken. Can attract the attention of infants, and is relatively safe because the sounding metal pill or small stone is placed in the ball body, and has been used for hundreds of years as the hearing training and toys for infants. However, most of the infants only change in shape and material, and have no improvement in connotation, the emitted sound is relatively monotonous and hard, and the infants feel dull and harsh after listening for a long time, and lose interest after often playing for a while.
