Abstract

This paper introduces a finger-ring shaped wearable HANDset. It uses the human finger as a transmission route for the receiving voice (bone conduction). Vibration noise is reduced using a newly-created microphone unit named "Duaphragm" that can suppress echo by about 70%. Duaphragm provides a small, low-power, and low-cost means of reducing vibration noise. In addition, a new LSI chip that integrates an accelerometer and a tapping command detector allows the handset to be controlled by tapping the fingertip on which the device is worn. Keywords: interface device, headset, noise cancel.
