Abstract: A loudspeaker transducer diaphragm or cone (e.g., 201, 301 or 401) is configured with arcuate protrusions that project distally from the main forward or distal surface 230 to provide stiffening and a break-up of resonant vibration modes when the loudspeaker is in use. The protrusions (e.g., 210, 310 or 410) are convex on one surface 230 and concave on the opposite surface 234, so their average thickness is similar to the frustoconical areas of the cone, i.e. they are shell-like in nature rather than solid mounds or walls. The protrusions 210 are generally curved as they run radially from the inner opening 204 to the outer peripheral edge to encourage modal break-up (suppressing strong vibrational modes, e.g., as in region 155).

Abstract: A method of conducting a wager game comprises allowing a player to place individual game wagers across a plurality of games to be played in the wager game. A common draw phase is implemented in which a plurality of symbols are randomly drawn from a symbol draw set to determine outcomes of the plurality of games, such chat at least one of the drawn symbols is used for determining, at least in part, the outcome for each of the plurality of individual games.
