Abstract
Coaxial transducers, some of which include a first assembly and assembly, each of which includes a magnet and a coil.
Claims26
-19. (canceled)
A transducer comprising:
- two coaxially-arranged assemblies that are coupled together, each assembly including a magnet and a coil, where one assembly at least partially overlaps the other assembly;
- and
- a housing to which one of the assemblies is coupled through at least one suspension element.
-26. (canceled)
A transducer comprising:
- a housing;
- a first magnet positioned inside the housing;
- a first coil positioned around at least a portion of the first magnet, the first coil being coupled to the housing, the first coil having a first outer perimeter;
- a second magnet coupled to the first magnet;
- and
- a second coil positioned around at least a portion of the second magnet, the second coil being coupled to the housing in substantially coaxial alignment with the first coil and having a second outer perimeter that is less than the first outer perimeter;
- where the first magnet is coupled to the housing and to the second magnet such that the first and second magnets are capable of moving together.
