This video was released around 2018, but was temporarily hidden from view due to rights issues.
I remembered those days and tried to upload it.
I would be happy if you could watch it.
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.

100均のスピーカーをバックロードホーンに改造しました。
木材をくりぬいて作製したエンクロージャーに装着。
エンクロージャーのタイプはバックロードホーンです。
【音質】
音道が80cmと短いながら低音が聞こえるようになりました。
木は比較的安価に手に入るゴムの集成材を利用。
MDFボードよりも硬質な木材のため、音がシャープになりました。
MDFで製作したエンクロージャーは「モコモコ」、「ゴソゴソ」した感じでしたがゴム集成材を使うことで音がのびやかになっています。
【エンクロージャーの設計】
エンクロージャーは広がり定数1.2で設計
スロート断面積は10ｃｍ^2
導管の長さは約80cm。
音道は出来るだけ計算値と一致するように最適化しています。
【製作について】
今回作ったエンクロージャはトリマーとノコギリ（動画ではバンドソーを利用）、ドリルがあれば製作できます。
