1. A housing component of a handheld electronic device, the housing component comprising: a cellular material which has a density of from 0.08 to 0.4 g/cc and a Young's modulus of from 32 to 650 Mpa,the cellular material being three-dimensionally shaped to form a substantially resilient body,the cel
1. A housing component of a handheld electronic device, the housing component comprising: a cellular material which has a density of from 0.08 to 0.4 g/cc and a Young's modulus of from 32 to 650 Mpa,the cellular material being three-dimensionally shaped to form a substantially resilient body,the cellular material is composed of a cellular polymer foam material having having open or closed cells, and the polymer foam material is composed of at least one of polyyinylchloride, polyurethane, polyethylene terephthalate, polymethacrylimide, polyetherimide, polyethersulfone, polystyrene, styrene acrylonitrile, and polysulfone andfurther comprising at least one surface layer on at least a part of at least one surface of the cellular material, wherein the at least one surface layer comprises a molded integral skin on the cellular material or at least one of a thermoplastic laminate film and a reinforcement adhered on the cellular material. 2. The housing component of claim 1 wherein the cellular material has at least one external surface which has been three-dimensionally shaped by at least one of machining and compression molding. 3. The housing component of claim l, wherein the integral skin is molded from same material as the cellular material. 4. The housing component of claim 1 wherein the thermoplastic laminate film is composed of at least one of polyurethane, polyethylene, polypropylene, polyvinylchloride, acrylonitrile butadiene styrene, polyester and polycarbonate. 5. The housing component of claim 1 wherein the at least one surface layer is applied to one surface or two opposite surfaces of the cellular material. 6. The housing component of claim 1 wherein the at least one surface layer is three-dimensionally shaped in common with the adjacent surface of the cellular material. 7. The housing component of claim 1 wherein the cellular material includes a plurality of openings in the form of holes or surface contouring in order to reduce the weight of the housing component without locally reducing the overall thickness of the housing component in the vicinity of the holes or surface contouring. 8. The housing component of claim 1 wherein the thermoplastic laminate film comprises at least one of an adhesive film, a stiffener film and an aesthetic surface film. 9. The housing component of claim 8 wherein the adhesive film has a thickness of from 25 to 130 microns, the stiffener film has a thickness of from 120 to 300 microns and the aesthetic surface film has a thickness of from 200 to 700 microns. 10. The housing component of claim 1 wherein the at least one surface layer comprises a coating applied on the cellular material. 11. The housing component of claim 10 wherein the coating is composed of at least one of a polymeric resin, a paint, and a metallic plating. 12. The housing component of claim 1 wherein the at least one surface layer has a density of from 0.05 to 7.2 g/cc. 13. The housing component of claim 12 wherein the at least one surface layer has a density of from 0.05 to 5.2 g/cc. 14. The housing component of claim 1 wherein the at least one surface layer is three-dimensionally shaped complementary with the adjacent surface of the cellular material. 15. The housing component of claim 14 wherein the at least one surface layer has been three-dimensionally shaped together with the cellular material by at least one of machining and compression molding. 16. The housing component of claim 1 which is selected from a chassis, a back cover, a front cover, an intermediate hardware enclosure, and a protective case of the handheld electronic device. 17. The housing component of claim 16 wherein the handheld electronic device is selected from a mobile phone, a cellphone, an e-reader, a tablet computer, a laptop computer, a netbook, an audio player, a video or still image player or camera, and a portable data storage device. 18. A handheld electronic device selected from a mobile phone, a cellphone, an e-reader, a tablet computer, a laptop computer, a netbook, an audio player, a video or still image player or camera, and a portable data storage device, the handheld electronic device incorporating or in combination with the housing component of claim 1.
