TWSU DIY Speaker Kit (Cardboard Speaker) is designed for use by individuals who are hard of hearing.  

Technical Specifications: 

Step 1: Things you will need

1. DIY Speaker Kit
2. The cardboard box that the kit came in
3. Scissors
4. Scalpel or craft knive
5. Ruler
6. Felt pen
7. A4 paper (a bit heavier like 120gsm)
8. Double sided tape
9. Double sided sticky pads

Step 2: Cutting opening for the speaker. Cut an opening where our speaker will sit. To do this we simply use our roll of double sided tape to mark a circle on the inside of our box. Make sure to position the opening to the right side of the box to leave enough space for the controls and amplifier. After you cut a circle out of the cardboard, keep the circle. It will be used for another step of the project.

Step 3: Making the speaker membrane. The special thing about this Speaker is that it is not a traditional speaker but an exciter instead. This exciter can be attached to any surface, which turns that material into a resonating surface to produce a sound.

1. Measure the size of the opening, adding another 30 millimeters to its radius.
2. Cut out a square off the sheet of our piece of paper 10 centimeters.
3. Attach the square piece of paper with double sided tape to the inside of the box, covering the entire opening

Step 4: Assembling the exciter. To improve the sound quality we want to add a buffer between our paper membrane and the actual exciter. This is where our cardboard circle off cut we kept earlier comes in handy.

1. What we need to do now is to make the cardboard disc a bit smaller by cutting off enough material to give the exciter enough space to sit on. You can play with the radius of the cardboard disc to see how this changes the sound quality. The author decided to have the cardboard disc with a slightly larger radius than the exciter itself.

2. The exciter comes with tape on one side which you can use to attach it to the cardboard disc.

3. Once the exciter is secured on the cardboard disc use two strips of double sided tape to secure the exciter with the cardboard disc to the inside of the box. Make sure that it sits square in the middle of our paper membrane. If you can't make out the center of the opening just hold the box against a light source, to reveal the size of the opening.

Step 5: Securing the amplifier. With the speaker unit assembled, the next step is to attach the amplifier on the inside of the box.

1. Cut off the left side flap of the box's lid leaving about 5 millimeters.
2. Using double sided sticky pads attach the amplifier with the battery facing the left side of the box and control facing the lid.

Make sure to keep the off-cut flap.

Step 6: Cutting openings for controls and input. Now we need to cut some opening for our controls and the 3.5 millimeter jack.

1. The easiest way to do it is to close the lid and gently press the cardboard against each control to get a slight indentation on the cardboard.
2. Use the indentations to mark where the holes will go
3. Using a scalpel or craft knife, cut three openings (one for the volume control, one for power switch and one for the input)
4. Once that is done, close the box and if everything is done right the holes should line up with our controls
Step 7: Attaching the stand: Place the speaker on its bottom edge, the speaker may be a bit unsteady. This can be addressed by adding a little stand using the off-cut flap we kept from step 5 stuck on with some double sided tape.

Once this is done we just need to wire everything up and turn on the music.
