Abstract
This invention relates to coil assemblies and in particular, but not exclusively, to such assemblies for acoustic transducers. Thus a transducer 10 includes a case 11 in which is located a coil 16 mounted on a flexi-circuit, which locates the coil 16 for its assembly handling and which allows various configurations within the case 11. A method of winding the coil 16 and mounting it on the carrier 17 is also described.
Claims4
A hearing aid transducer comprising:
- a coil assembly including a fine wire coil having a body and a set of leads and a flexible carrier incorporating electrical paths extending from a first set of terminals to a second set of terminals;
- the coil body being directly mounted by means of an adhesive on the carrier and the leads being electrically connected to the first set of terminals;
- and
- a case having a slot through which the carrier extends such that the second set of terminals are external to the case.
