Abstract:
A pickup assembly for stringed musical instruments comprising: a six-sided, rectangularly shaped chassis (30) with one side being not completely closed so as to afford access to any subdivision of space within the interior, the total interior space being subdivided lengthwise by a plurality of partitions (31), the partitions defining volumes of space which are approximately parallel to one another and which are of similar dimension, each subdivision of interior space having a center axis oriented lengthwise and parallel to the plane between this axis and the long axis of a string (32) in tension immediately adjacent to, and outside of, this partition of space, the interior partitions (31) not serving as structural support for the chassis;a surface of the chassis (30) closest to the plane of the instrument's strings (32) being a closed surface except for the presence of one lengthwise opening of uniform width associated with each interior subdivision of space within the chassis, each opening on this surface being parallel to the long center axis of the interior partition of space with which it is associated, these openings of uniform width being referred to as tracks (14) and the surface comprising a plurality of tracks being referred to as a trackbed (14a);a plurality of blocks (21a), comprised of two parts, (21b) and (21c), the length of each block being shorter than the length of the volume of space defined by the partitions (31) within the chassis (30) but whose respective width is approximately equal to any of these volumes of space, at least one block (21a) being slideably disposed per interior volume of space within the chassis (30) as well as per string (32) of the associated instrument; there being a T-shaped structure (21b) atop and connected to each block (21c) such that the vertical element of the T-shaped structure (21b) fits within a track (14) and the horizontal aspect of the T-shaped element (21b) is situated flush with the exterior surface of the trackbed (14a); manual or mechanical movement of the T-shaped structure (21b) causing subsequent repositioning of its associated block (21c) within the chassis (30), range of motion of the T-shaped structure (21b) and the block (21c) to which it is attached being limited to a line parallel to the center axis of the volume of space within which the block shaped element (21c) is slideably disposed; a second block-shaped component (20) which attaches to the surface of the horizontal aspect of each T-shaped component (21b) closest to the associated string; this second block (20) being a signal sensor.
