Background

The straw is a sucking tool which is frequently used by people in daily life, and is an important tool for infants to drink water, porridge and other drinks, the infants often cannot suck food through the straw stably, and the problem to be solved for the infant straw is how to grasp the attention of the infants. The suction pipe is the first choice of the baby sucking tool, the sound generating device can be arranged on the pipe body, and the sound is generated through the suction pipe to attract the attention of the baby, so that the baby can use the suction pipe voluntarily. The prior sounding straw has the following problems:

1. install sound producing component in the straw, the sound production principle is that the flow through liquid drives sound producing component action and makes a sound, can lead to remaining liquid (for example milk) on the sound producing component easily like this, all will carry out careful washing to sound producing component after using the straw at every turn, otherwise remaining liquid can lead to sound producing component smelly, breeds harmful bacterium even. Representative patents reflecting the above disadvantages include "a music straw" disclosed in chinese patent document CN201879364U and "a music straw" disclosed in chinese patent document CN 103783955A.
