（2) What kind of music boxes can you make other than heart-shaped ones?
（3) If you were asked to make a music car, how would you make it?
1. Prepare before class
According to Lesson 1.1 of “Magic Brush Ma Liang”, draw the car in your mind on paper with a pen.
2.Software Design
（1) Design the car parts by referring to the content of Lesson 1.1 of the special course of “Magic Brush Ma Liang”
（2) Reduce the production of a welding plate.
（3) Drill holes in one of the carts (pictured) the holes are 3.1mm and 7mm in size (for mounting the music box movement)
(Tip: The distance between the two empty seats should be designed according to the distance between the winding of the music box movement and the screw binding place)
Add gears
（4）Click “Gallery” on the menu bar at the top of the software, select the gear graph under the picture, drag it to the blank interface, and then copy and paste it into 3 (as the rear wheel of the car).
（5) Change the diameter of the gear hole of one of them to 4.60mm.
3.Machine demonstration
（1)Import the design file demonstrated above into the laser cutting machine for processing.(Tip: Remember to adjust the focal length before processing to avoid impenetrable cutting.)
4.Splicing assembly
（1) Install the car according to the stitching steps in lesson 1.1 of Magic Brush Ma Liang.
(Tip: the rear wheel does not need to be installed, the welding plate is attached to the front)
（2) Take out the spring handle of the movement of the music box and put the movement through the 7mm round hole, align the screw hole with the other hole and tighten the screw.
（3) Install a gear with a diameter of 4.60mm on the position of the spring and screw on the spring handle.
（4) The 3.1mm gear as the rear wheel, use a small stick to install the gear in the back of the car, installation, pay attention to the gear between the gear to kiss.
（1) What problems did we meet in the production process?
（2) The music car is too small. I want to make it bigger. How do I make it?
（3) The car is too slow, how to speed it up?

1. Teaching introduction
Guide students to the class topic by asking questions:
（1) Recall, what is the source of the music box? How does it work?
Source: Dates back to the Renaissance in medieval Europe. At that time, in order to make the clock tower of the church, the mechanical device of the size of the clock was called “the group of bells that can make a sound”.
Principle: The main part of the music box is composed of power source (spring or crank and other power source), sound cylinder, sound board, damping, bottom plate, transmission mechanism and other parts. The spring drives the drum to rotate, and the solder joint on the drum moves the edge of the chip thin strip, vibrates to make a sound, and turns down to form a movement.
The roller can be regarded as a musical score, and the maker will add solder spots to the roller according to the musical score.
The chip, on the other hand, can be seen as a piano key, which cuts thin strips (frequencies) of different lengths on the same piece of material. The more thin strips on the chip, the higher the number of notes, the richer the timbre and the better the tune.
（2) What kind of music boxes can you make other than heart-shaped music boxes?
Like a music buggy.
（3) If you were asked to make a music trolley, how would you make it?
Watch the video: After watching the video, are you already eager to make your own music car? Now let’s get into the production process!
2.Painting
According to Lesson 1.1 of “Magic Brush Ma Liang”, draw the car in your mind on paper with a pen.
3.Teaching demonstration
（1) Design the car parts by referring to the content of Lesson 1.1 of the special course of “Magic Brush Ma Liang”
（2) Reduce the production of a welding plate.
（3) Drill holes in one of the carts (pictured) the holes are 3.1mm and 7mm in size (for mounting the music box movement)
(Tip: The distance between the two empty seats should be designed according to the distance between the winding of the music box movement and the screw binding place)
Add gears
（4) Click “Gallery” on the menu bar at the top of the software, select the gear graph under the picture, drag it to the blank interface, and then copy and paste it into 3 (as the rear wheel of the car).
（5) Change the diameter of the gear hole of one of them to 4.60mm.
4.Machine demonstration
Import the design file demonstrated above into the laser cutting machine for processing.
(Tip: Remember to adjust the focal length before processing to avoid impenetrable cutting.)
5.Splicing assembly
（1) Install the car according to the stitching steps in lesson 1.1 of Magic Brush Ma Liang.
(Tip: the rear wheel does not need to be installed, the welding plate is attached to the front)
（2) Take out the spring handle of the movement of the music box and put the movement through the 7mm round hole, align the screw hole with the other hole and tighten the screw.
（3) Install a gear with a diameter of 4.60mm on the position of the spring and screw on the spring handle.
（4) The 3.1mm gear as the rear wheel, use a small stick to install the gear in the back of the car, installation, pay attention to the gear between the gear to kiss.
5.Student operation
（1)Preparation before class: Hand out paper and pens for hand-drawing.
（2)Software design: Guide the students to complete the design according to the requirements on the design draft, and assist the students to transfer the design file to the laser cutting matching computer named after the name and student number.
（3)Machine processing: Guide students to complete the machine processing steps in the order of completing the design.
（4)Splicing and Assembly:Distribute tools in groups and guide students to complete the assembly of works independently.
（1) What problems did we meet in the production process?
（2) The music car is too small. I want to make it bigger. How do I make it?
（3) The car is too slow, how to speed it up?
