Abstract: A water resistant speaker having a water-impermeable spider and an acoustic chamber in air flow communication with the underside of the spider via vents in a spider support and vents in a bottom panel of a basket of the speaker. The acoustic chamber is attached and sealed to the bottom of the basket and is watertight. The acoustic chamber may have a passive radiator. The combination of a water impermeable spider and a water impermeable diaphragm, adjacently attached and sealed to the former, assist in preventing water from reaching the magnet assembly and voice coil. A water impermeable dust cap is attached and sealed to the diaphragm to prevent water from entering around the former. A vent in the pole piece, leading to the acoustic chamber, reduces drag on motion of the former, dust cap, and diaphragm.

Abstract: A water resistant speaker having a water-impermeable spider and an acoustic chamber in air flow communication with the underside of the spider via vents in a spider support and in a bottom panel of a basket of the speaker. The acoustic chamber is attached and sealed to the bottom of the basket. At least one hydrophobic vent is supported in the wall of the acoustic chamber or in the basket behind the spider to limit air pressure in the acoustic chamber. The acoustic chamber may have a passive radiator. The combination of a water impermeable spider and diaphragm, adjacently attached and sealed to the former, assist in preventing water from reaching the magnet assembly and voice coil. A vent in the pole piece, leading to the acoustic chamber, reduces drag on motion of the former, dust cap, and diaphragm.
