Abstract: A grill device may include an accessory rail assembly including at least one accessory rail. Each accessory rail may include an upper flange, a lower flange, and a web extending between and connected to the upper flange and the lower flange. Additionally, a plurality of brackets may connect the web to a cooking portion assembly of the grill device. An accessory may include at least one attachment structure. The attachment structure may include an upper feature sized and shaped to wrap around and conform to a portion of a surface of an upper flange of an accessory rail, and a lower feature sized and shaped to wrap around and conform to a portion of a surface of a lower flange of the accessory rail. A shelf accessory may include a shelf, a first bracket, and a second bracket.

Abstract: An apparatus comprises an electronic device having at least one speaker and a passive sound proliferation device comprising an audio cavity. The audio cavity is configured to proliferate acoustic waves therefrom and is defined by at least a substantially planar back wall, a substantially planar side wall, an arcuate surface between the substantially planar side wall and the substantially planar back wall, and a substantially planar inner bottom surface. The passive sound proliferation device may further include a substantially planar outer side surface and a substantially planar outer bottom surface substantially perpendicular to the substantially planar outer side surface. The electronic device may be disposed within the audio cavity. Related methods of directing audio from a passive sound proliferation device are disclosed.
