The voice coil that fits into the magnetic gap of the magnetic circuit is connected, and the surface material on the side where the free edge of the flat diaphragm is pasted is made slightly larger than the outer diameter of the core material, and the part that protrudes outward from the core material is used to create a large amplitude vibration. A flat speaker made by bending the free edge to an angle that prevents contact when it is stretched.
