Planar Speaker PCB - Homemade HiFi Headphones

?What is a planar speaker and how to make one using flexible PCBs and planar magnets. I&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. ?LINKS ------------------------------------- ?SUPPORT ------------------------------------- 00:00 Intro 01:18 How a speaker works? 01:48 Planar speaker 02:35 The PCBs 03:33 Circuit Design 06:09 3D Design 07:18 First Test 08:50 Amplified test 09:21 Frequency response 11:16 Thank You Like share and subscribe to motivate me.
