Load speaker device i.e. low sound speaker device, for use in e.g. low supersonic device, in building, for generating or reproducing sound waves, has de-coupling module integrating vibration exciter into internal volume of building element

摘要

The device (10) i.e. low sound speaker device, has casing-less electro-acoustic vibration exciters (16, 18) including front sides (20, 22) and rear sides. An acoustic de-coupling module (28) includes minimum depth of about 50 mm and separates partial volumes that are assigned to front- and rear sides of the exciters. The acoustic de-coupling module acoustically integrates one of the vibration exciters into an internal volume e.g. acoustic active volume, of a building element (14), and partially and acoustically connects the internal volume with the front and rear sides of the exciters. Independent claims are also included for the following: (1) a supersonic device i.e. low supersonic device, comprising a building element (2) a method for manufacturing a supersonic device.
