1. A portable wireless battery powered speaker comprising:
- a chassis defining an internal compartment and having a space defined by a radial support surface of the chassis and a bottom cover, wherein the chassis further comprises a bottom side, and wherein the chassis comprises a plurality of steps from the radial support surface to the bottom side, including at least a first step on the radial support surface and a last step on the bottom side;
one or more active drivers mounted to said chassis;
a retention gasket having a distal surface, the retention gasket secured to said chassis and disposed within the space defined by the radial support surface and the bottom cover;
a passive radiator having an outer perimeter portion that is fixedly held in position between said distal surface of retention gasket and said first step of the radial support surface of said chassis with compressive force against the outer perimeter of said passive radiator; and
wherein the bottom cover is attached to at least the last step on the bottom side of the chassis.

Abstract
A battery powered wireless audio speaker comprising a passive radiator is disclosed. The perimeter portion of the passive radiator is sandwiched between the speaker chassis and the retention gasket that resides between an external overlying perforated cover to firmly secure the passive radiator. The construction is capable of being well suited to enhance and improve integrity to the seal between the passive radiator and the speaker chassis in strenuous environment conditions such as when a speaker is submerged in water.
