This week, I made three speakers using fabric. I did not use the conductive thread to sew. I used normal cotton thread to sew over the conductive one to adhere it to the fabric.

One is made of a square of softer fabric and conductive thread.(fig.1)

One is made of a square of softer fabric and conductive yarn.(fig.2)

Because it’s said the stiffness of fabric will also affect the volume. Too soft ones will absorb the vibration. I thought the fabric I used for the 1st and 2nd was too soft, so for the 3rd one, I changed to a square of stiff fabric. It is made of a square of stiff fabric and conductive thread.(fig.3)
