Abstract
A vehicle headrest includes an electro-acoustic transducer and an acoustic enclosure. The acoustic enclosure defines an acoustic chamber. The acoustic enclosure supports the electro-acoustic transducer such that a rear radiating surface of the electro-acoustic transducer radiates acoustic energy into the acoustic chamber. A cushion member is coupled to the acoustic enclosure for supporting a user's head. A grille member overlies a front radiating surface of the electro-acoustic transducer. The grille member is formed of a 3D printed lattice.
Claims20
A vehicle headrest comprising:
- an electro-acoustic transducer;
- an acoustic enclosure defining an acoustic chamber, the acoustic enclosure including a baffle member that supports the electro-acoustic transducer such that a rear radiating surface of the electro-acoustic transducer radiates acoustic energy into the acoustic chamber, wherein the baffle member includes a plurality of recesses;
- a cushion member coupled to the acoustic enclosure for supporting a user's head, wherein the cushion member includes a mounting member comprising a plurality of features for engaging the plurality of recesses in the baffle member, thereby to couple the cushion member to the baffle;
- a grille member overlying a front radiating surface of the electro-acoustic transducer, the grille member comprising a 3D printed lattice;
- and
- a first coupling member supported by the grille member for coupling the grille member to the acoustic enclosure, wherein at least one of (a) the 3D printed lattice defines a recess for receiving the coupling member or (b) the first coupling member is formed integrally with the 3D printed lattice.

A loudspeaker comprising:
- an electro-acoustic transducer;
- an acoustic enclosure defining an acoustic chamber, the acoustic enclosure including a baffle member that supports the electro-acoustic transducer such that, during operation, a rear radiating surface of the electro-acoustic transducer radiated acoustic energy into the acoustic chamber, wherein the baffle member includes a plurality of recesses configured to engage with a plurality of features associated with a cushion member for supporting a user's head;
- a grille member overlying a front radiating surface of the electro-acoustic transducer, the grille member comprising a 3D printed lattice;
- and
- a first coupling member supported by the grille member for coupling the grille member to the acoustic enclosure, wherein at least one of (a) the 3D printed lattice defines a recess for receiving the first coupling member and (b) the first coupling member is formed integrally with the 3D printed lattice.
