Abstract: A sound attachment for a reed instrument such as a harmonica. A housing is provided having an open end adapted for attachment to the instrument, covering the full width of the portion of the instrument from which sound is emitted, and a closed opposite end. Interior walls of the housing converge from the open end to an area intermediate the length of the housing, defining a sound funnel. A sound absorbing collar is mounted transversely within the housing, located between the intermediate area and the closed end of the housing, and has an electronic sound pick up element mounted therein. The pick up element is located to provide an air chamber on both sides of the collar pick up element assembly, the rear chamber being at least partially filled with sound absorbing material such that virtually total sound from the instrument is received by the pick up element with very little or no distortion, and thus may be amplified without distortion.

Interior walls of the housing converge from the open end to an area intermediate the length of the housing, defining a sound funnel. A sound absorbing collar is mounted transversely within the housing, located between the intermediate area and the closed end of the housing, and has an electronic sound pick up element mounted therein. The pick up element is located to provide an air chamber on both sides of the collar pick up element assembly which achieves a balanced condition such that when the chambers are filled with air, virtually total sound from the instrument is received by the pick up element with very little or no distortion, and thus may be amplified without distortion.
