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 coupled to a metallic component. The metallic component may be configured to couple to a magnetic field created by the bone-conduction transducer.

主权项

1. An apparatus comprising:
a bone-conduction transducer comprising a diaphragm configured to vibrate in response to a magnetic field generated by the bone-conduction transducer; a mount coupled to an external surface of the diaphragm; an anvil configured to contact a surface of the skin of a wearer and to conduct the vibration from the diaphragm; at least one metallic component located within the anvil and on a top surface of the mount, configured to couple to the magnetic field of the bone-conduction transducer and cause a desired acoustic frequency response for the bone-conduction transducer; and wherein the mount is located between the diaphragm and the metallic component.
