ABSTRACT:
A tennis racket has a frame member forming a head portion having duplicate strung ball striking matrices, each matrix being substantially coplanar with a respective front and rear face of the frame member. The matrices are formed with a plurality of intersecting string lengths, each being threaded through an aperture extending between the front and rear face of the frame member. In an alternate embodiment each string length traverses a respective front or rear face and then is passed through a radially directed aperture connecting an outer margin of the frame with an inner margin. A signal device is attachable to the matrices for emitting an audible response upon ball impact within a prescribed locus on the matrix.
