Abstract

PURPOSE:To achieve uniform radiation sound horizontally, by providing a diaphragm having circular band shape flexibility and oscillating the same with deformation while circular shape, in obtaining a non directional speaker. CONSTITUTION:A magnet 3 is provided at the inner center of a circular band shape diaphragm (radiator) 1, and disc shape yoke 2 is provided up and down the sides. A sound absorbing member 4 is contained in a gap between the radiator 1 and the magnet 3. On the surface of a thin nonconductor 5 forming the radiator 1, a conductor voice coil 6 is attached, and the coil 6 is expanded along the nonconductor 5 through wave shaped form for flexiblity. The radiator 1 like this has expansion nature radially and it deforms while being circular form for oscillation, and it radiates sound equally horizontally.
