Manufacturing method of housing and electronic device

An electronic device, comprising:

• a plurality of electric components;
• a housing for providing an accommodating space in which the plurality of electric components is accommodated;
• a first part of the housing being made of a single first material into a uniform construction which is integrally molded;
• the first part of the housing having a plurality of recesses arranged in a first arrangement, and the plurality of recesses being formed by recessing an outer surface of the first part of the housing inwardly;
• and
• the outer surface of the first part of the housing being provided with spaces for spacing the plurality of the recesses, and the spaces being formed between any two of the recesses on the outer surface of the first part of the housing after the outer surface of the first part of the housing being recessed inwardly to form the plurality of the recesses;
• wherein:
• portions of the outer surface of the first part of the housing which have the plurality of recesses are arranged to face away from the accommodating space and exposed in an outside of the housing;
• a second material effect exhibits on the first part of the housing by the plurality of the recesses and the spaces, and the second material is different from the first material;
• a textile effect presents on the first part of the housing by the plurality of the recesses and the spaces and the second material effect is the textile effect, and the textile effect is embodied in visual and/or tactile senses sensed by an observer of the electronic device when observing the outer surface of the first part of the housing;
• a texture in a first direction and a texture in a second direction constituted by the plurality of recesses and the plurality of spaces present the textile effect seen by an observer of the electric device, demonstrating that the texture in the first direction interweaving with the texture in the second direction, or when the user touches the device, present a tactile feeling of textile;
• and
• the first part of the housing comprises an edge area and a central area, and the edge area surrounds the central area, and the edge area corresponds to an edge of the electronic device, and the plurality of the recesses comprise a first recess located in the edge area and a second recess located in the central area, a depth of the first recess being smaller than that of the second recess.
