????What is a planar speaker and how to make one using flexible PCBs and planar magnets. I’ve made a 3D design for the enclosure and test the results with a frequency response software. The PCB has the coils but also acts as a membrane. This is just the first attempt and it looks promising! Very good sound quality.
