Paper Speakers

Inspired by Marcelo Coehlo’s paper speaker and Vincent Leclerc’s Accouphene textile speaker, these paper and fabric speakers are made by running 5-9V amplified sound signal through a very conductive coil in close proximity to a magnet. Unlike most speakers that have the wire coil wrapped cylindrically and placed around the magnet, here the coil is in the plane and directly adhered to the membrane that moves the air creating sound.

The coils can be made from a variety of conductive materials. Copper tape, conductive fabric tape, conductive fabric and stainless steel thread work really well. gold leaf does not work as well (yet!) in comparison. The coil can be one sided or two sided. A continuous spiral gives better results than one that backs up on itself.

The coils can be fused to a variety of membrane materials such as paper, vellum, veneer, fabric, transparency, tissue paper…

Step-by-Step Instructions

Ingredients: copper tape, conductive fabric, stainless steel thread, gold leaf, paper, wood, fabric, double-sided sticky (studio tack), size (gold leaf tacky adhesive)
Equipment: Lasercutter, vinylcutter (Craft Robo), scissors, paint brushes, carving tool
Downloads:Illustrator file of speaker coils, some of which were hand drawn

Create a coil shape

Draw and scan or create in software.

Cut the coil

Depending on what material you are using (copper tape, conductive fabric, thread, paint…) you’ll have different ways of creating your coil.

Sound amplification circuit

Using a TIP 120 transistor to control a 5V or a 9V power supply from a microcontroller, in this case a sound circuit taken from a toy that plays the same song every time the button is pressed.

    Its really an awesome Idea!
    I’m an Engineering student, I needed a project idea and I was searching for something interesting like that for so long!!
    I’m Going to make it myself, And I think these speakers can be improved by a little alteration,(like supporting the edges of paper to focus all the vibration in the middle of the paper to make the sound clear) because the sound was not clear,but of course it’s just a theoretical huntch , I’m really glad that I found your website.
    I will follow your leads to make it and would try to improve it to higher level.
    thank you so much !!!
