FIELD: physics, acoustics.SUBSTANCE: group of inventions relates to acoustics and particularly to sound reproducing means. The loudspeaker includes a diaphragm extending from an internal area to an external area, wherein the external area is bent at an angle of 45-135 degrees relative to the internal area of the diaphragm. The apparatus also includes a frame, a suspension element extending from an internal suspension area to an external suspension area. The external suspension area adjoins the frame. The internal suspension area overlaps the external area of the diaphragm and is connected thereto to form an interface region having a vibration limiting portion directed at a given angle relative to the internal area of the diaphragm. The orientation of the vibration limiting portion at a given angle insulates the internal area of the diaphragm from parasitic flexural waves propagating from the external suspension area, and the bending angle gives rise to a shearing force in the interface region, which reinforces said interface region. The internal suspension area and the external area of the diaphragm are fastened with an adhesive. The frame also includes an adjusting ring.EFFECT: high sound quality.20 cl, 6 dwg |
