ABSTRACT:
A loudspeaker is designed for mounting on a wall and which uses the wall to help generate sound from electrical signals supplied by an amplifier. The magnetic assembly consists of three disk shaped layers, the outer layers being a magnet and a ferromagnetic pole plate, the layers being separated by a spacer made of resilient material. The magnet and spacer both have roughly identical holes which are coaxially aligned. A center pole, on which a voice coil is wound, extends from the pole plate through the hole in the spacer and partially into the hole in the magnet. A frame serves to hold the magnetic assembly and press the magnet against the wall during operation. Electrical signals fed to the voice coil cause the magnet to vibrate against the wall, exciting the wall to create sound energy.
