ACOUSTIC SYSTEM FOR DISPLAY EQUIPMENT Russian patent published in 2004 - IPC

FIELD: acoustic systems for display equipment. SUBSTANCE: proposed system has cover frame built integral with loudspeaker. The latter functions to produce sound and cover frame, to attach it to rear cover plate. Cover frame and loudspeaker are integrated by means of adhesive joint. Loudspeaker has gasket in the form of track which is a flush with cover frame built integral with loudspeaker so as not to form any clearance for passing sound in forward direction. System also has rear cover plate to constitute box for improving resonance properties and for attaching to underside of cover frame integrated with loudspeaker to secure it on display equipment casing. Such design provides for raising efficiency and precludes forward sound pressure loss caused by backward sound leakage. EFFECT: reduced loudspeaker-induced vibration of system which precludes vibration of its casing. 14 cl, 13 dwg
