Bone-conduction anvil and diaphragm

摘要

Disclosed herein are methods and apparatuses for the transmission of audio information from a bone-conduction headset to a user. The bone-conduction headset may be mounted on a glasses-style support structure. The bone-conduction transducer may be mounted near where the glasses-style support structure approach a wearer's ears. In one embodiment, an apparatus has a bone-conduction transducer with a diaphragm configured to vibrate based on a magnetic field. The magnetic field being based off an applied electric field. The apparatus may also have an anvil coupled to the diaphragm. The anvil may be configured to conduct the vibration from the bone-conduction transducer. Additionally, the anvil may be anvil may include at least one component configured to change properties to enable the bone-conduction headset to couple to the head of a user with greater than a threshold amount of force.

主权项

1. A transducer comprising:
a diaphragm, wherein the transducer is configured to vibrate the diaphragm based on a signal supplied to the transducer; an anvil coupled to the diaphragm, wherein the anvil is configured to vibrate in response to vibration of the diaphragm; and an adjustable component coupled to a top surface of the anvil and configured to vibrate with the anvil; wherein the apparatus is coupleable to a wearable support structure in an arrangement such that when the wearable support structure is worn, vibration of the transducer is transferred to a posterior of an ear via the adjustable component; and wherein rigidity of the adjustable component is adjustable based on an applied electrical signal that alters a rigidity parameter that is associated with the adjustable component.
