Adjustment mechanism for tissue transducer
A headset includes a tissue transducer on a carriage that translates along a temple portion of the headset. The carriage is configured to contact the helix root of a user's ear. The helix root provides a reference point, and when the carriage is contact with the helix root, the tissue transducer is configured to be located in a target area. By maintaining a fixed location of the tissue transducer relative to the helix root of the user's ear, the tissue transducer may be accurately positioned, even for users with different head shapes and sizes.
1. An adjustable transducer assembly comprising:
a tissue transducer configured to provide audio content to a user of a headset;
a motor;
a carriage, driven by the motor, configured to translate along a temple of the headset, the carriage coupled to the tissue transducer and including an indexing feature, wherein the indexing feature is configured to translate with the carriage along the temple in a direction toward a rear portion of the headset until the indexing feature contacts a helix root of an ear of the user; and
a closed-loop feedback system, in response to the indexing feature contacting the helix root of the ear, configured to cause the motor to stop driving the carriage such that the indexing feature is positioned against the helix root and the tissue transducer is positioned to provide the audio content via tissue conduction to a target area.
2. The adjustable transducer assembly of claim 1 , wherein the motor is further configured to position the tissue transducer based on an input from the user.
3. The adjustable transducer assembly of claim 1 , wherein the tissue transducer comprises a cartilage conduction transducer, and wherein the target area is a tragus of the ear of the user.
4. The adjustable transducer assembly of claim 1 , wherein the indexing feature is rotatably coupled to the carriage.
5. The adjustable transducer assembly of claim 1 , wherein the tissue transducer is located at least partially within the carriage.
6. The adjustable transducer assembly of claim 1 , wherein the tissue transducer is coupled to the indexing feature via a hinge.
7. The adjustable transducer assembly of claim 1 , wherein in response to an input, the tissue transducer is configured to move from a cartilage conduction position to a bone conduction position, or from the bone conduction position to the cartilage conduction position.
8. A headset comprising:
a frame including a temple;
an adjustable transducer assembly coupled to the temple, the adjustable transducer assembly comprising:
a tissue transducer configured to provide audio content to a user of a headset, a motor,
a carriage, driven by the motor, configured to translate along a temple of the headset, the carriage coupled to the tissue transducer and including an indexing feature, wherein the indexing feature is configured to translate with the carriage along the temple in a direction toward a rear portion of the headset until the indexing feature contacts a helix root of an ear of the user, and
a closed-loop feedback system, in response to the indexing feature contacting the helix root of the ear, configured to cause the motor to stop driving the carriage such that the indexing feature is positioned against the helix root and the tissue transducer is positioned to provide the audio content via tissue conduction to a target area.
9. The headset of claim 8 , wherein the tissue transducer comprises a cartilage conduction transducer, and wherein the target area is a tragus of the ear of the user.
10. The headset of claim 8 , wherein the motor is further configured to drive the carriage along the temple.
11. The headset of claim 8 , wherein the indexing feature is rotatably coupled to the carriage.
12. The headset of claim 8 , wherein the tissue transducer is located at least partially within the carriage.
13. The headset of claim 8 , wherein the tissue transducer is coupled to the indexing feature via a hinge.
14. The headset of claim 8 , wherein in response to an input from the user, the tissue transducer is configured to move from a cartilage conduction position to a bone conduction position.
15. A headset comprising:
a frame including a temple;
a motor;
a carriage, driven by the motor, configured to translate along the temple in a direction toward a rear portion of the headset until the carriage contacts a helix root of an ear of a user;
a closed-loop feedback system, in response to the carriage contacting the helix root of the ear, configured to cause the motor to stop driving the carriage; and
a cartilage conduction transducer coupled to the carriage, wherein the cartilage conduction transducer is configured to contact a tragus of the user.
16. The headset of claim 15 , further comprising an indexing feature configured to contact the helix root.
17. The headset of claim 16 , wherein a distance between the indexing feature and the cartilage conduction transducer is fixed.
18. The headset of claim 16 , wherein the cartilage conduction transducer is coupled to the indexing feature via a hinge.
