Abstract

A linkage assembly (140) is used for mechanically coupling an armature (124) and a diaphragm (118) of a balanced receiver (100), the linkage assembly (140) formed from a first linkage member (822) displaced from a strip of stock material (800) relative to the plane of the stock material (800) and a second linkage member (826) displaced from the strip (800) relative to the plane. The first and second linkage members (822, 826) are then joined while secured to the strip (800). At least one severable connecting member (870a-c) securing the linkage member to the strip (800) is severed to release the linkage member from the strip for assembly of the linkage member into the receiver. A method of forming a three-dimensional structure from flat stock is used to form the linkage assembly (140).

Claims5

Dependent claims

A system of components usable in the manufacture of an acoustic transducer, the system comprising:

a strip, the strip including a substrate having formed therein a plurality of first transducer assembly components, the first transducer assembly components being supported by the strip;
a plurality of second transducer assembly components, the second transducer assembly components being arranged in an array such that at least one second transducer assembly component is aligned with and secured to a corresponding first transducer assembly component supported by the strip;
wherein each of the plurality of first transducer assembly components comprises a linkage assembly;
wherein each of the plurality of second transducer assembly components comprises one of a receiver housing, an armature, a diaphragm or a receiver subassembly;
wherein each second transducer assembly component is welded, bonded or mechanically fastened to the corresponding first transducer assembly component.
