Shared coil receiver
First Claim
1. An apparatus comprising:
- a coil;
a stationary core, wherein the coil is wound about a portion of the stationary core;
a first magnetic structure and a second magnetic structure, wherein the first magnetic structure and the second magnetic structure are coupled to the stationary core;
a first armature having a first end of the first armature and a second end of the first armature, wherein the first end of the first armature is coupled to the stationary core and the second end of the first armature is disposed within the first magnetic structure;
a second armature having a first end of the second armature and second end of the second armature, wherein the first end of the second armature is coupled to the stationary core and the second end of the second armature is disposed within the second magnetic structure.

10. An acoustic receiver comprising:
-
an electrical coil wound about a non-moving core having a first portion on one side of the electrical coil and a second portion on an opposite side of the electrical coil, the first and second portions of the non-moving core having opposite sides; a first pair of permanent magnets disposed in space-apart relation adjacent one side of the first portion of the non-moving core; a second pair of permanent magnets disposed in space-apart relation adjacent the opposite side of the first portion of the non-moving core; a first armature coupled to the second portion of the non-moving core, the first armature including a portion disposed and movable between the first pair of permanent magnets; a second armature coupled to the second portion of the non-moving core, the second armature including a portion disposed and movable between the second pair of permanent magnets, wherein application of an excitation signal to the electrical coil causes movement of at least one of the first armature between the first pair of permanent magnets or the second armature between the second pair of permanent magnets. - View Dependent Claims (11, 12, 13, 14, 15, 18)
