Adjustable spring assembly for a vibrator of a bone anchored hearing aid |
摘要 |
Spring assembly as part of a vibrator for a bone anchored hearing aid, wherein the spring assembly comprises a suspension spring having a first end immovably connected to a mass of the vibrator and a second end immovably connected to a coupling attachable to a user's skull bone and comprised by the vibrator, wherein the spring assembly comprises an adjusting means adapted to adjust a spring rate of the suspension spring between a first spring rate and a second spring rate, the first rate being higher than the second rate, so as to move a resonance peak of the vibrator. |

1. A spring assembly for a vibrator of a bone anchored hearing aid, the spring assembly comprising:
a suspension spring having a first end immovably connectable to a mass of the vibrator and a second end immovably connectable to a coupling attachable to a user's skull bone and comprised by the vibrator; and an adjuster configured to adjust a spring rate of the suspension spring between a first spring rate and a second spring rate, the first rate being higher than the second rate, so as to move a resonance peak of the vibrator, wherein the suspension spring is designed as a planar spring with the first end being located in a peripheral region, the second end in a center region of a plane of the spring, and an axis of displacement is defined perpendicular to the plane and extending through the center region. |
