Wangzai Can Speaker
Print Profile(1)
Description
For making a small Bluetooth speaker from a 245ml Wangzai milk can
Total cost within 50.
The mesh on the top cover is an additional cylinder; you can choose its shape and density when slicing. Print the two parts centered and aligned
The opening plate can be used to help mark and make openings
The speaker used is a 3-inch 5-watt full-range speaker with a diaphragm size of 65mm, which perfectly matches the can's bottom size.
The Bluetooth board purchased is a DUA-benli mono TWS module.
The lining can be used to help fix the Bluetooth module and battery. I use a short cylindrical lithium battery (the Bluetooth module does not have protection, so the battery needs a protection board)
Do not use 18650! It will be blocked by the speaker!
The module has TWS function; two can automatically pair for stereo sound
For parts, it is recommended to use paste adhesives such as structural silicone or nail-free adhesive.
After assembly, remember to wait until the glue is completely dry before testing!
