Thinking/Creating with Active Materials

DIY Speaker Loops

A simple loud speaker can be made from conductive ink, a magnet and any thin material.


A simple loud speaker can made by hand by either printing or painting a conductive ink coil on any thin material. Alternatively a thin wire can be embed or glued to the materials surface to form the coil. When each termination of the coil is connected to the positive and negative of an amplifier and suspended over a magnet an electroacoustic transducer is formed.
