The horn is a very good toy for young children, which can attract childrens eyes and interest very well.
I remember when I was a child, I used to run around with a trumpet. It was very interesting.
What I show you here is the production process of a toddler toy speaker. You can imagine what it looks like.
As for whether it can make a sound, you need to explore it yourself.
Use paper to roll out a coneObjects, and also prepare some straws, pencils, scissors and tape paper.
Flatten one side of the straw and cut it into the shape as shown in the illustration.
Draw the part that needs to be cut out on the cone object. The size of the cut part needs to be such that the straw can be put in.
Cut the drawn vertices as well.
Insert the straw and secure it with tape.
Then you can take this small trumpet and blow it to see the specific effect.
When you have nothing to do, you can take this small speaker out to show off.
I remember when I was a child, I felt very envious when I saw children holding speakers.
