  • Patent number: 4976648
    Abstract: The call includes an elongate tubular body having a rim structure defining an elliptical air inlet end. An elastic sheet constitutes a reed and overlies a portion of the inlet end of the body. A backing plate is also located at the inlet end with a plate tongue offset below the elastic sheet. The rim structure is shaped so as to support a span of the elastic sheet in spaced relationship to the backing plate which is received on a recessed portion of the rim structure and held in place by the elastic sheet. An O-ring secures the sheet in place. An adapter adjacent the outlet end of the tubular body permits attachment of a sound absorbent tube for sound modulation. A baffle within the adapter provides an airflow restriction. The backing plate is removably mounted on the tubular body of the call and allows backing plate of different configurations to be used to alter the pitch of the call.
