Nonlinear suspension component in a tissue conducting vibration isolation system
A tissue conduction audio system includes a transducer that produces vibrations as it presents audio to a user. A vibration isolation system isolates the vibrations produced by the transducer. The vibration isolation system includes a suspension component with flexures that are configured to have an asymmetric spring rate when at rest and a symmetric spring rate when the transducer is in use and/or at a target position.
1. A vibration isolation system comprising:
a suspension component that includes a plurality of flexures that together are configured to isolate vibrations produced by a transducer, the plurality of flexures including at least one set of flexures that have a symmetric spring rate for a target position of the at least one set of flexures, and an asymmetric spring rate for a resting position of the at least one set of flexures.
2. The vibration isolation system of claim 1 , wherein the at least one set of flexures has a symmetric geometry in response to bearing a load.
3. The vibration isolation system of claim 2 , wherein responsive to bearing the load, the at least one set of flexures is displaced relative to a lateral axis.
4. The vibration isolation system of claim 1 , wherein the at least one set of flexures has an asymmetric spring rate due to one or more material properties.
5. The vibration isolation system of claim 4 , wherein the material properties comprise one of a thickness and a type of material.
6. The vibration isolation system of claim 1 , wherein the transducer is part of a headset.
7. The vibration isolation system of claim 6 , wherein the target position of the at least one set of flexures occurs when the headset is coupled to a user.
8. The vibration isolation system of claim 6 , wherein the vibration isolation system is positioned on an arm of the headset.
9. The vibration isolation system of claim 6 , wherein the transducer is configured to present audio via at least one of bone conduction or tissue conduction.
10. A system comprising:
a transducer configured to present audio, the transducer producing vibrations while presenting the audio; and
at least one set of flexures coupled to the transducer and configured to isolate the produced vibrations, wherein the at least one set of flexures have a symmetric spring rate for a target position of the at least one set of flexures, and an asymmetric spring rate for a resting position of the at least one set of flexures.
11. The system of claim 10 , wherein the at least one set of flexures has a symmetric spring rate in response to bearing a load.
12. The system of claim 11 , wherein responsive to bearing the load, the at least one set of flexures is displaced relative to a lateral axis.
13. The system of claim 11 , wherein the at least one set of flexures has an asymmetric spring rate due to one or more material properties.
14. The system of claim 13 , wherein the material properties comprise one of a thickness and a type of material.
15. The system of claim 10 , wherein the transducer is part of a headset.
16. The system of claim 15 , wherein the target position of the at least one set of flexures occurs when the headset is coupled to a user.
17. The system of claim 15 , wherein the at least one set of flexures is positioned on an arm of the headset.
18. The system of claim 15 , wherein the transducer is configured to generate sound via at least one of bone conduction or tissue conduction.
