Abstract
An implantable component, such as by way of example, an implantable component of a transcutaneous bone conduction device, the implantable component comprising a piezoelectric transducer, wherein the implantable component is configured to temporarily prevent the piezoelectric transducer from moving inside the housing while the housing is implanted in the recipient.
Claims34
A component of a prosthesis, comprising:
- a housing of the prosthesis;
- and
- a transducer, wherein
- the component is configured to temporarily limit movement of the transducer, and
- the component is configured to unlimit movement, after temporarily limiting movement, of the transducer.
A component of a bone conduction device, comprising:
- a housing;
- and
- a transducer-seismic mass assembly, wherein
- the component is configured to automatically temporarily shock-proof the assembly via energy transfer into or out of a material.
A component of a bone conduction device, comprising:
- a housing;
- and
- a transducer, wherein
- the component includes a fluid located therein, wherein the component is configured to control the fluid to temporarily at least limit movement of the transducer relative to that which is the case in the absence of the fluid, and
- at least one of:
- the fluid is a phase transitioning fluid that transitions from a fluid to a solid to at least limit movement of the transducer;
- the fluid is a magnetorestrictive fluid;
- or
- the component is configured to impart thermal energy into the fluid so as to one of temporarily at least limit movement of the transducer relative to that which is the case in the absence of the fluid or stop and/or reduce the temporarily at least limiting of the movement of the transducer relative to that which is the case in the absence of the fluid.
A method, comprising:
- obtaining a component of a bone conduction device including a transducer located within a housing,
- 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;
- and
- at least one of prior to or subsequent to the action of 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, enabling the transducer to fully flap or enabling the transducer to flap more than the limited amount and operating the transducer such that the transducer bends upwards and/or downwards to produce vibrations that evoke a first hearing percept via bone conduction.
