Grille for electroacoustic transducer
Abstract:
A grille for an electroacoustic transducer. The grille has a frame defining a length, a width, and a depth, the frame configured to cover at least a portion of the electroacoustic transducer, and the frame configured as substantially acoustically transparent relative to the electroacoustic transducer. The frame has an energy absorption capacity such that for a mass of 6.8 kg impacting the frame at a speed of 24.1 km/h, the 3 ms deceleration is no more than 80 gs.
