Abstract
A component of a bone conduction device, including a housing and a piezoelectric bender located in the housing, wherein the component is configured to limit bending of the piezoelectric bender relative to that which would otherwise be the case in the absence of the limits via application of a stopping force at a centralized location of an assembly of which the bender is a part.
Claims29
A seismic mass transducer comprising:
- a seismic mass;
- and
- a transducer, wherein
- the seismic mass is configured to contact the transducer to prevent over-deflection of the transducer.
1 more element
A component of a bone conduction device, comprising:
- a housing;
- and
- a piezoelectric bender located in the housing, wherein
- bending of the piezoelectric bender is damped via at least one of gas damping or shear damping.
1 more element
A method, comprising:
- obtaining a component of a bone conduction device including a transducer-seismic mass assembly located within a housing;
- and
- operating the transducer of the assembly such that the transducer bends upwards and/or downwards to produce vibrations that evoke a first hearing percept via bone conduction while preventing the transducer from fully flapping or limiting an amount of flap of the transducer relative to that which the transducer can flap without the limitation, wherein
- the seismic mass assembly is free of contact with the housing during normal operation other than via the transducer.
