The above and related objects are achieved by providing a device (membrane) comprising a geometrically configured head of the racket (tennis, etc.) where there is an increased power released upon hitting an object due to the geometric design that incorporates geometry and physics. This design has a particular emphasis to the various zones individually and/or jointly in the head of the racket. The device provides for both ease of attachment of strings to the head of the racket and of application (increased or focused) pressures to the ball or object being hit.
