Abstract:
A method of forming a device having a compliant member includes creating a membrane having one or more elastomeric layers which are at least partially cured. Another elastomeric layer is provided on the membrane in an uncured state. At least one of a bobbin and a housing are positioned so that an end of the bobbin or housing, or the ends of both the bobbin and housing, extend at least partially into the uncured elastomeric layer. The uncured elastomeric layer is then cured to secure it to the membrane and to the housing or bobbin, or both the housing and bobbin. The method substantially reduces or eliminates the formation of holes that can form during fabrication or use of the device.
