If digital voice is played suddenly, it means that it is too sensitive and switched to the internal space of the chip. The 1.4K resistor should be changed to 1.5K, or the 22uf capacitor should be changed to 10uf.
Introduction:

Assembly & welding instructions
Use 2 pieces of the circular bottom plate under the character stand and stack them together, then fix them on the rocking spring with UV glue to
make a The printed magnetic cover needs to be equipped with 3 magnets to attract
the PCB of the rocking spring. Use 2 self-tapping screws to fix
the middleware. Pay attention to the direction
when installing the shell. The first installation of the assembly will be very tight. After several disassembly and assembly, it will gradually become loose. Then install the PCB, battery and speaker.
The welding patch is not resistant to high temperature and is easy to break. It is necessary to pay attention to the temperature not being too high for too long, within 300 degrees for 1 second.

Printing instructions
FDM: The printing middleware cannot have elephant feet. If there are any, they need to be polished off.
Because the printing effects of different printers and different brands of materials are slightly different, two assembly gaps of tight and loose are made. Print tight first. If it is still very loose after printing, increase the extrusion amount.
 
Light curing:
        I haven't tried it yet, but I feel that it should be printed with tight assembly.
