10 the other pole of cymbal element 10 is connected to metal ribbon 28 b together this results in a parallel electrical connection of all of the elements the ribbons 28 a and 28 b maintain mechanical and electrical contact with the respective studs 20 a and 20 b via nuts 30 and washers 32 fig2 b shows a partially cutaway side views of an array of cymbal elements 10 held in the mounting 24 fig2 c is a view looking from the top of the array fig3 a 3 b and 3 c show an alternative mounting configuration for the cymbal elements 10 fig3 a shows an array of cymbal elements 10 in a partially cut away side view and fig3 b shows a top view of an array using this mounting in this embodiment the cymbal elements 10 are held in place around their outside rim with a rubber grommet 34 within a stiff grid 36 grommet 34 absorbs vibrations and prevents transfer of these vibrations to grid 36 or between elements 10 grommet 34 has an inner groove 38 receiving cymbal element 10 and an outer groove 40 contacting grid 36 the projector design taught in this invention allows for great flexibility in electrical wiring configurations for instance instead of electrically wiring in parallel such as in the device described above each cymbal element 10 or groups of cymbal elements could be wired for individual addressing by individual wires or other conductors 42 which combine to form a wiring harness 44 the bottom side can be configured in a similar fashion or it can use the conductive ribbons taught in fig2 c and 3c this would allow for manipulation of electrical impedance control of beam forming capability through variation of the radiating aperture.
