The head is applied in electric acoustics. It reduces the amplitudinal-frequency and phase distortions and offers expanded frequency band in the high-frequency area. The mobile system of the loudspeaker contains a round diaphragm, formed by a pack of bands fixed between membranes. Along the diaphragm periphery, symmetrically to its axis, are ribs with trapezium-shaped cross-section with height 2+- 0.5 of the diaphragm thickness and length 0.5-0.7 of the diaphragm radius. The length of the bottom cross-section base is 0.1-0.2 of its height, while the length of the upper base is between 0.2 to 1.0 of the lower base length.
