Claim Text:
1. An apparatus comprising: a support structure having two side-arms; at least one bone-conduction transducer mounted to at least one of the side-arms, wherein the bone-conduction transducer comprises a diaphragm configured to vibrate in response to a magnetic field generated by the one bone-conduction transducer, and wherein the side-arm positions the bone-conduction transducer to the posterior of a wearer's ear; a mount coupled to an external surface of the diaphragm; an anvil coupled to the external surface of the diaphragm, wherein the anvil is configured to conduct the vibration from the diaphragm, and wherein the anvil is coupled to the support structure via a sheath; and at least one metallic component (i) aligned to the mount and (ii) located within the anvil, wherein the metallic component is configured to couple to the magnetic field of the bone-conduction transducer and cause a desired acoustic frequency response for the bone-conduction transducer.
