MICROPHONE MATRIX FOR RECORDING BODY SOUNDS

摘要

The invention provides a microphone matrix for recording body sounds, such as respiratory tract sounds. The matrix has a frame having one or more recesses or openings on one of its surfaces. A microphone assembly is disposed in each recess or opening in the frame. When a body portion is applied to the matrix, each microphone assembly moves from an extended, spring biased position in which at least a portion of the microphone assembly protrudes beyond the surface of the frame towards a retracted position in which the microphone assembly is deeper inside the recess.
