VISUAL DISPLAY MEANS INCORPORATING LOUDSPEAKERS

摘要

The visual display unit (137) comprises a display screen (37) and a housing (101) in which the display screen is mounted. The housing carries a loudspeaker (81) comprising a distributed mode acoustic radiator (2) and a transducer (9) mounted wholly and exclusively on the radiator to vibrate the radiator to cause it to resonate. The radiator may be integral with the housing, e.g. an external wall of the housing. The radiator may comprise a stiff lightweight panel having a cellular core sandwiched by skin layers, one of which skin layers is integral with the housing. The skin layer may be thinner than the average wall thickness of the housing. The external wall of the housing may be formed with a groove which surrounds the radiator and which defines a resilient suspension coupling the loudspeaker to the housing.
