Electronic device housing and method for manufacturing the same

Abstract

A housing ( 10 ) used in portable electronic devices includes gripping portions ( 40 ) defined thereon, such gripping portions being bounded by grooving created in a surface of the housing. A method of manufacturing the housing is also provided, the method includes these steps: forming a housing; grinding the housing; polishing the housing; and forming the gripping portions on the housing.

1 . A portable electronic device housing comprising a surface and a plurality of gripping portions defined in the surface of the housing, such gripping portions being bounded by grooving created in the surface of the housing. 
   
   
       2 . The housing as claimed in  claim 1 , wherein the gripping portions protrude from their surroundings. 
   
   
       3 . The housing as claimed in  claim 1 , wherein the gripping portions are rhomboid-shaped. 
   
   
       4 . The housing as claimed in  claim 1 , wherein the gripping portions are formed by two groups of arcs, wherein each arc in a respective group of arcs crosses a plurality of arcs of the other of the two groups, and all arcs of a same group are arranged to be essentially equidistant from any adjacent arc in a given same group. 
   
   
       5 . The housing as claimed in  claim 1 , wherein the housing is made of a material comprised of at least one of copper, iron, aluminum, and titanium. 
   
   
       6 . A method for manufacturing a housing, comprising these steps:
 forming a housing;   polishing the housing; and   forming gripping portions on the housing by employing an engraving step.   
   
   
       7 . The method as claimed in  claim 6 , wherein the housing is made of a material comprised of at least one of copper, iron, aluminum, and titanium. 
   
   
       8 . The method as claimed in  claim 6 , further comprising a step of washing the housing after the step of polishing the housing. 
   
   
       9 . The method as claimed in  claim 6 , wherein the step of forming gripping portions on the housings includes performing a first engraving procedure along a first direction and a second engraving procedure along a second direction that crosses the first direction. 
   
   
       10 . The method as claimed in  claim 9 , wherein the housing is substantially rectangular, the first direction corresponds to a first diagonal of the housing, and the second direction corresponds to a second diagonal of the housing. 
   
   
       11 . The method as claimed in  claim 6 , further comprising a step of anodizing the housing after forming gripping portions on the housing. 
   
   
       12 . The method as claimed in  claim 11 , further comprising a step of dyeing the housing after the step of anodizing the housing. 
   
   
       13 . The method as claimed in  claim 12 , further comprising a step of forming a protecting film on the housing after the step of dyeing the housing.
