1. A method of fabricating a device having a compliant member, comprising:

  • applying heat to a thermoplastic elastomer to maintain the thermoplastic elastomer in a softened state;

    extruding the thermoplastic elastomer in the softened state into a film of thermoplastic elastomer;

    positioning one or more of a bobbin and a housing, each having an end, such that the end of the bobbin and/or housing extends at least partially into the film of thermoplastic elastomer, the positioning occurring when the thermoplastic elastomer is in the softened state and/or the bobbin and/or housing is at a temperature that is greater than a temperature of the film of thermoplastic elastomer; and

    cooling the film of thermoplastic elastomer having the bobbin and/or housing positioned therein, wherein the bobbin and/or housing is thereby secured to the film of thermoplastic elastomer.
