Abstract
A panel of acoustically reflective material is removably supported on the bell of a wind instrument by a bracket which is jointed so that selectively the panel can be, (1) angularly positioned to reflect the sound back to the player or in other directions, (2) moved toward and away from the bell to adjust reflection of the sound, (3) moved to a muting position, and (4) moved to a non-reflecting location.
Claims9
In an acoustical reflector of the type having a panel with an acoustically reflective surface and bracket means on said panel including a clamp adapted to be mounted on the rim of the bell of a wind instrument for supporting said panel generally in front of the bell, improved structure wherein said bracket means comprises,
- a rod connected with said panel by means including an articulable joint,
- said clamp having means forming a socket which supports a portion of said rod,
- said socket being so oriented that when said clamp is mounted on the rim of the bell of an instrument with which said reflector is adapted to be used when the axis of said rod is generally parallel to the axis of the instrument bell,
- said rod portion being axially movable relative to said socket through a distance sufficient to facilitate locating said panel axially clear of the bell of the instrument when said panel is positioned in axial alignment with the bell,
- said rod portion being rotatable relative to said socket for swinging said panel about said rod axis when said panel is so located and positioned,
- and means effective to secure said rod against axial and rotatable movement relative to said socket.
In an acoustical reflector of the type having a panel with an acoustically reflective surface and bracket means on said panel including a clamp adapted to be mounted on the rim of the bell of a wind instrument for supporting said panel generally in front of the bell, improved structure wherein said bracket means comprises,
- a rod connected with said panel by means including an articulable joint,
- said rod and clamp being cooperable to support said panel in alignment with but axially clear of the bell of an instrument with which said reflector is adapted to be used,
- said rod being rotatable relative to said clamp for swinging said panel transversely of the instrument bell,
- said rod having a bend between said clamp and joint to generate conical movement of said joint and panel upon rotation of said rod relative to said clamp.
