11019444 · 2021-05-25 · ·

A method of forming a device having a compliant member includes applying heat to a thermoplastic elastomer to maintain the thermoplastic elastomer in a softened state. The thermoplastic elastomer is extruded in the softened state as a film of thermoplastic elastomer. One or more of a bobbin and a housing, each having and end, is positioned such that the end extends at least partially into the film of thermoplastic elastomer. The positioning occurs 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. The film is cooled so that the bobbin and/or housing are secured to the film and so that the thermoplastic elastomer is in a state that exhibits rubber-like properties.
