Abstract:
1. An apparatus comprising: a shell member having an interior width, wherein the shell member includes a closed end and an open end, wherein the shell member comprises a resonator shell; a nut comprising a plurality of laterally extending resilient legs, wherein the legs define an outer width of the nut, wherein when the plurality of laterally extending resilient legs are in a relaxed state the outer width of the nut is greater than the interior width of the shell member, wherein the nut is adapted for at least partially entering the open end of the shell member such that the plurality of laterally extending resilient legs are placed in a tensioned state in which the plurality of laterally extending resilient legs define the outer width of the nut being smaller than or equal to the interior width of the shell member; and a base plate adapted for receiving the shell member and securing the shell member member to the base plate with the closed end of the shell facing away from the base plate through cooperation with the nut when the nut is at least partially within the shell member.
