摘要： 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.

摘要： A multi-layered laminate for producing membranes for electroacoustic transducers, comprises a first layer of a polyether ether ketone film having a heat of crystallisation of at least 15 J/g, a second layer (of a thermoplastic plastic film having a heat of crystallisation of no more than 5 J/g, and an adhesive layer arranged between the first and second layers. Alternatively, the first and second layers are defined by their shrinkage properties after 15 minutes at 200° C.: the first layer has shrinkage of more than 10% in at least one direction, and the second layer has shrinkage of less than 10% in the longitudinal and transverse directions. A laminate constructed in this manner exhibits lower fold formation when processed using multi-cavity thermoforming. The laminates are useful for the production of membranes for electroacoustic transducers.

摘要： An acoustic unit, which is arranged for coupling with a vibration system to produce an audio sound, includes a frame, a vibration member for being reciprocatingly moved in response to the vibration system; and a resilient suspension which is provided around the vibration member and is located between the vibration member and the frame, wherein the suspension has a stretching section integrally extended from the vibration member and a cushioning section integrally extended from the stretching section to the frame. The cushioning section only allows the stretching section to displace along a direction the same as a vibration direction of the vibration member to restrict a vibrating movement of the vibration member. The acoustic unit is incorporated with an acoustic module, wherein when a loudspeaker of the acoustic module operates, the acoustic unit synchronously vibrates to provide an enhanced low frequency audio effect.
