Claims

[Scope of utility model registration request]

A plurality of magnet elements having different diameters having a magnetic gap formed by sandwiching both the inner and outer surfaces of a cylindrical ring magnet between two inverted-shaped pole pieces are arranged concentrically to constitute a magnet body that forms a magnetic field, and a magnet body that forms a magnetic field is configured. Each driving conductor through which a current flows in the direction is arranged in each of the magnetic gaps, and each driving conductor is connected to each joint of a group of vibrating elements in which vibrating elements formed in a substantially semi-cylindrical shape are concentrically connected. The circular diaphragm is generally composed of the group of vibrating elements that are fixed and moved in parallel when a driving force from the driving conductor is applied to each joint, and the circular diaphragm is given elasticity only in the driving direction. A circular plane drive type speaker characterized in that an edge portion is provided on the outer periphery of the diaphragm, and the edge portion is fixed via a braking member.
