| description | An acoustic accessory is provided having a loudspeaker and a circuit board disposed therein. An acoustic suspension system is formed within the acoustic accessory by board retention rings disposed within the upper and lower housings of the accessory. The board suspension rings clench the printed circuit board, which includes at least one aperture. Rubber gaskets are coupled to the board retention rings to form an airtight seal. The air mass above the printed circuit board joins with the air mass below the printed circuit board to form a unitary reactance against which the loudspeaker works. The size and number of apertures may be varied in accordance with the acoustic application. Board retention posts optionally seat within notches in the printed circuit board to prevent the printed circuit board from moving laterally. Electrical connections may be made through the printed circuit board into the acoustic chamber, thereby not compromising the airtight seal. |
