Abstract
An electronic device includes a first portion, a second portion, and a joint moveably coupling the first and second portions for angular adjustment between the first and second portions. A speaker is fixed on the first portion at a first known distance from the joint, and a microphone is fixed on the second portion at a second known distance from the joint. An angle sensing machine is configured to emit a known sound from the speaker, detect the known sound at the microphone, and measure a transmission time of the known sound from speaker to microphone. Based on the transmission time, a current angle of the first portion relative to the second portion is calculated.
