Abstract
The invention relates to audio transducers, such as loudspeaker, microphones and the like, and includes improvements in or relating to: audio transducer diaphragm structures and assemblies, audio transducer mounting systems; audio transducer diaphragm suspension systems, personal audio devices incorporating the same and any combination thereof. The embodiments of the invention include linear action and rotational action transducers. For both types of transducer, rigid and composite diaphragm constructions and unsupported diaphragm periphery designs are described. Systems and methods for mounting the transducer to a housing, such as an enclosure or baffle are also described. Furthermore, hinge systems including: rigid contact hinge systems and flexible hinge systems are also disclosed for various rotational action transducer embodiments. Various applications and implementations are described and envisaged for the audio transducer embodiments including, for example, personal audio devices such as headphones, earphones and the like.
