Modified cheap $3 speaker - Awesome sound quality



Published
I made remake of the $ 3 speaker.
I attached it to an enclosure made by hollowing out wood.
The type of enclosure is backload horn.

【Sound quality】
I could hear the bass while the sound path was as short as 80 cm.
Wood utilizes laminated rubber of rubber available at a relatively inexpensive price.
It is harder than the MDF board, so the sound sharped.
Although the enclosure manufactured with MDF was a feeling of being caught, the sound has become more vigorous by using rubber laminated wood.


【Design of enclosure】
Enclosure designed with spreading constant 1.2
The throat cross section is 10 cm ^ 2
The length of the conduit is about 80 cm.
The sound path is optimized to match the calculated value as much as possible.


【Production】
The enclosure we made this time can be produced with trimmer and saw blade (using band saw for animation), drilling.
The tree block is ordered on the net. I had you cut it to the specified size.
