Introduction: Home Theater Using Cardboard
Checkout this low cost and DIY Cardboard 2.1 Home Theater System (Transmission line System)
1. Cardboard and black chart paper
2. Cutter & Pen/Pencil
4. 2.1 Home Theater System Circuit Kit
5. Sub-Woofer and two small Speakers
6. Four Screws and nuts
I have used my old 2.1 sub woofer system.
This is an entry in the
Trash to Treasure
Step 1: Making of Medium Level Acoustic Sound Chamber Base
I am used refrigerator cardboard package to build this whole sound system.
Step 2: Making Medium Level Acoustic Transmission Line
This step shows how I built transmission line System. Here I am designed like, to get different medium level acoustic sound within the cardboard chamber, the walls of the each passage is finished with 270GSM black chart sheets, so that walls of passage became more solid to reduce absorption of sound.
Step 3: Making High Level Acoustic Transmission Line
This steps shows making high level acoustic sound, here also the walls of the transmission/passage is finished with 270GSM black chart sheets. The size/lenghth of the transmission lines/passages are just an assumption
Step 4: Sub-Woofer Chamber
The woofer chamber are made up with five layered cardboard sheets (including outer covers), it reduces the vibration. Speaker mounted on four layered cardboard panel using screw and nuts.
Step 5: Making Outer Case of Sub-woofer and Transmission Line Chamber
The minimum thickness of the cases ( Transmission line, sub woofer cabinet ) are kept 20mm (3 layers of cardboard sheets). All over the sub woofer box has 5 layers of cardboard sheets, (Including 2 outer layers).
Step 6: Making Outer Case of Tower Speakers and Its Grills
Making of tower speaker chamber.The grils of each chamber made up of with same cardboard sheets, need to cut in sqare shape as shown in pic.
Step 7: Making Power Amp Chamber
I have used my old 2.1 sub woofer system for this project,
Step 8: Completed 2.1 Sub-woofer System
Completed cardboard home theater system for final modification.
Step 9: Final Cardboard Home Theater System
This is final output of the cardboard home theater system. The upper portion is modified with 270GSM black chart paper, and grils are painted with black water colour.
When I tested this the acoustic sound has not come as I assumed but can feel the slight acoustic audio output, It gives different sounds, I liked it .
