RESONANT MODE PANEL-LOUDSPEAKERS

摘要

A resonant panel-form loudspeaker characterised by suspension means located in at least one panel region of low average velocity. A method of making a resonant panel acoustic device characterised by locating at least one panel region of low average velocity and positioning suspension means within the said region(s). The method may comprise delineating an acoustically active area of a larger panel, e.g. a motor vehicle decorative trim panel, by grooving or slotting the panel in panel regions of low average velocity.
