Abstract
A transducer assembly with a U-shaped element at least a part of which forms a part of a magnet housing is disclosed. One or more magnets are attached to the magnet housing which is adapted to conduct magnetic flux from one or more magnets.
Claims20
A motor assembly for a transducer assembly for a hearing aid, the motor assembly comprising:
- a magnet housing having an inner surface;
- a U-shaped element having a secured leg portion which is secured to the magnet housing, and a movable leg portion which is adapted to be secured to a diaphragm of the transducer assembly;
- a coil;
- and
- one or more magnets;
- wherein the magnet housing encircles the one or more magnets and the movable leg portion in a plane having a normal which extends parallel to a general direction of the movable leg portion;
- and
- wherein at least a part of the magnet housing is defined by the secured leg portion and at least a part of the inner surface is defined by the secured leg portion.

A transducer assembly for a hearing aid comprising:
- a housing;
- a first diaphragm which divides a first inner space of the housing into a primary part and a secondary part;
- and
- a first motor assembly having a U-shaped element including (i) a first secured leg portion and (ii) a first movable leg portion which is secured to the first diaphragm, the first motor assembly further comprising:
- a coil;
- one or more magnets;
- and
- a magnet housing element secured to the first secured leg portion of the U-shaped element, the magnet housing element and at least a part of the first secured leg forming a magnet housing having an inner surface at least a part of which is defined by the first secured leg portion;
- wherein the magnet housing encircles the one or more magnets and the first movable leg portion in a plane having a normal which extends parallel to a general direction of the movable leg portion.
6 more elements
