A Fully Functional Speaker.

This is a 3d printed speaker that I made just for fun. It sounds wonderful!

You need: a super glue, a wire(around 2-3 m), a neodinium magnet and a resistore (and now a very important thing. the resistor is necessary only if you would like the speaker to be very loud. It should be the same as the bluetooth receiver. ex: I have a receiver that say the speaker I would put at it should have 4 ohm, so I plug in series with one of the speaker wire a resistor rated at 4 ohm. The information about the proper rated resistence of the bluetooth module you can find online or on the website you buy it ).

The magnet has the dimensions of 45 mm in diameter and 30 mm in height. It is rated at 70 kg force. It is essential for a strong bass.

After the files are printed, wire up the middle piece, but keep at each end around 10-20 cm of wire. It is the file named speaker (6). After the wire is nice and tight put super glue on the whole surface.

Place the magnet in the middle socket with a little bit of glue.

Place the ring on top of the last part.

Place the TPU membrane inside the part with the colons and glue it down. Next take the part that stay on top (named speaker 5) and place on the other side of the membrane, with the cone facing up.

Glue down the coil part and the cone. Try to center them as much as possible.

Finally, fit the 2 main parts together, but be careful to take out the wire like in the image and be in tension.

Congratulations! You did it!
