Abstract: A mounting bracket and an arrangement for mounting an electronic accessory device within the mounting bracket when installed in a vehicle not only holds the device for its intended use but also permits limited withdrawal for insured and normal access to the control panel for desired adjustment. The mounting bracket is comprised of a base plate and a pair of opposed, complementary flat arms depending from opposite ends of the base plate for stationing of an electronic device within the mounting bracket. Each of the arms includes a pair of channels for guiding displacement of the stationed device within the mounting bracket. One of the channels is generally straight, and the second of the channels is generally serpentine and spaced from the first channel between the first channel and the base plate.

Abstract: An acoustical transducer and grille combined into a single unit. The grille is acoustically transparent and includes a plurality of wave guides separated for through-passage of sound. Situated in the midst of the grille is a mounting for the acoustical transducer. The transducer mounting has a central opening and an annular groove formed about the periphery of the central opening into which the acoustical transducer is mounted. A second acoustical transducer, larger in dimension than the first acoustical transducer, may be employed as well, also mounted within the confines of the grille. For greatest acoustical clarity, the first and second acoustical transducers are coaxially oriented.
