Abstract
A transducer having a housing defining a chamber, a bent armature with a first leg and a second leg, a magnet assembly for providing a magnetic field in an air gap, and a coil comprising a coil tunnel. The coil tunnel and the air gap extend substantially parallel or perpendicular to each other. Furthermore, the first leg extends in a first direction through the coil tunnel and the second leg extends in a second direction through the air gap.
Claims15
A transducer comprising:
- a housing defining a chamber,
- a U-shaped armature having at least a first leg and a second leg, the first leg having a first length, and a bent portion interconnecting the first and second legs,
- a magnet assembly configured to provide a magnetic field in an air gap, and
- a coil comprising a coil tunnel,
- wherein the armature extends through the air gap and the coil tunnel and is fixed to the housing at an end portion of the first leg, so that the second leg and at least a portion of the first leg, the portion extending from the bent portion and comprising at least 50% of the first length, are movable in relation to the housing,
- wherein the armature has a U-shaped portion where the first leg and the second leg are substantially parallel, and
- wherein the coil tunnel and the air gap extend substantially parallel to each other, and wherein one of the second leg and the portion of the first leg extends through the coil tunnel and the other of the second leg and the portion of the first leg extends through the air gap.

A transducer comprising:
- a housing defining a chamber,
- an L-shaped armature having at least a first leg and a second leg, the first leg having a first length, and a bent portion interconnecting the first and second legs,
- a magnet assembly configured to provide a magnetic field in an air gap, and
- a coil comprising a coil tunnel,
- wherein the armature extends through the air gap and the coil tunnel and is fixed to the housing at an end portion of the first leg, so that the second leg and at least a portion of the first leg, the portion extending from the bent portion and comprising at least 50% of the first length, are movable in relation to the housing, and
- wherein the first leg extends in a first direction through the coil tunnel and the second leg extends in a second direction through the air gap, wherein the coil tunnel and the air gap extend transverse to each other.
