Smart sensing bone conduction transducer

摘要

Example methods and devices are provided related to bone conduction. A bone conducting transceiver (BCT) is provided. The BCT includes a metal spring, an anvil, a base, and at least one sensor. The metal spring has two ends. The anvil is mounted on an upper surface of the metal spring and is configured to move in conjunction with the metal spring based on an input signal. The base contacts a lower surface of the metal spring and supports at least one end of the two ends of the metal spring. The at least one sensor is configured to generate data regarding at least one characteristic of the BCT.

1. A bone conducting transceiver (BCT), comprising:
a metal spring having two ends; an anvil, mounted on an upper surface of the metal spring and configured to move in conjunction with the metal spring based on an input signal; a base, contacting a lower surface of the metal spring and supporting at least one end of the two ends of the metal spring; and at least one sensor, configured to generate data regarding at least one characteristic of the BCT, wherein the data comprises impedance data; and a signal controller configured to:
determine whether or not the impedance data includes a spike within a pre-determined range of frequencies;if it is determined that the impedance data includes the spike, set a gain of the input signal to a first gain level; andotherwise, set the gain of the signal to a second gain level, wherein the first gain level differs from the second gain level.
