Grille for electroacoustic transducer
First Claim
Patent Images
1. A grille for an electroacoustic transducer that is set in a recess in a headrest, comprising:
- a frame configured to cover the recess and comprising a first wall, and a second wall disposed substantially perpendicularly to the first wall, the first and second walls each having a front surface, and a rear surface that is exposed to the recess, and a plurality of spaced ribs that are coupled to the rear surfaces of both the first wall and the second wall, where the frame is substantially acoustically transparent relative to the electroacoustic transducer, andthe frame being a unitary molded member that 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.

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.

10. An automobile headrest system, comprising:
-
a) a headrest having; a headrest frame, a reaction plate coupled to the frame, a cushion material disposed about the frame and reaction plate, a first electroacoustic transducer disposed in a first recess at a first end of the headrest, a second electroacoustic transducer disposed in a second recess at a second end of the headrest, the first end opposing the second end; b) a first grille disposed in proximity to the first electroacoustic transducer; and c) a second grille disposed in proximity to the second electroacoustic transducer; wherein each of the first grille and the second grille comprises a grille frame configured to cover one recess and comprising a first wall, and a second wall disposed substantially perpendicularly to the first wall, the first and second walls each having a front surface, and a rear surface that is exposed to the recess, and a plurality of spaced ribs that are coupled to the rear surfaces of both the first wall and the second wall, where the frame is substantially acoustically transparent relative to the electroacoustic transducer, the frame being a unitary molded member that 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
