Abstract: Method and system are disclosed for facilitating automatic assembly of electroacoustic transducers for listening devices, such as hearing aids. The method and system provide the components of the electroacoustic transducer in the form of carriers. Each carrier includes a frame surrounding a preformed component. The preformed component is attached to the frame by at least one strut that holds the component in a fixed position within the frame. The frame may then be used as a guide or reference for mounting other components (whether provided on component carriers or not) to the preformed component. Some components, instead of being in a carrier, may be preassembled as a subassembly and then mounted to other components that are in a carrier. Several carriers may be connected sequentially in a strip and run through an assembly line to facilitate automatic assembly of multiple electroacoustic transducers in parallel.

Abstract: A receiver is disclosed for use in listening devices, such as hearing aids. The receiver comprises an electromagnetic drive assembly that includes a bobbin having a coil of conductive wire formed thereon. The bobbin is capable of compensating for the deflections on the armature that may be caused by shock. The bobbin is also capable of centering an armature leg within the coil.
