It will be appreciated that the number of at least one hollow area 1 is set according to the number of closed contour lines in the preset mark. I.e. the number of at least one hollow area 1 depends on the number of closed contour lines in the predetermined marking, all hollow areas 1 forming the predetermined marking.
In one embodiment, referring to fig. 4, when the preset mark includes a closed contour line, the preset mark is a logo corresponding to the mobile terminal 100, the logo is "O", that is, the preset mark has only one closed contour line, and the laser cutting machine cuts a hollow area 1 in the preset area. The hollow region forms an "O".
In another embodiment, referring to fig. 5, when the preset mark includes at least one closed contour line, the preset mark is taken as a logo corresponding to the mobile terminal 100, the logo is "OP", for example, the preset mark has two closed contour lines, and correspondingly, the laser cutting machine cuts a hollow area 1 corresponding to "O", and then the laser cutting machine cuts another hollow area 1 corresponding to "P", that is, one closed contour line in the preset mark corresponds to one hollow area.
The at least one hollow area 1 not only can radiate radio frequency signals as a clearance area of the housing 10, but also can be an inevitable mark on the mobile terminal 100, thereby optimizing the structure of the housing.
Specifically, the hollow region is filled with the non-signal shielding material 2 to form a clearance region for passing the radio frequency signal of the antenna 40, and it can be understood that the non-signal shielding material 2 is plastic, rubber or glue, and in this embodiment, the non-signal shielding material 22 is plastic, which further facilitates the transmission of the radio frequency signal.
Further, referring to fig. 3, the mobile terminal 100 further includes an antenna 40, and it is understood that the antenna 40 is an NFC antenna, and the antenna 40 is disposed inside the mobile terminal 100 and faces the at least one hollow area 1 to radiate radio frequency signals.
The housing 10 and the mobile terminal 100 in the embodiment of the present invention optimize the structure of the housing 10 and the mobile terminal 100 by laser-cutting at least one hollow region 1 corresponding to a closed contour line of a preset mark in the housing 10, and simultaneously filling the at least one hollow region 1 with the non-signal shielding material 2, so that not only can the at least one hollow region 1 pass radio frequency signals, but also the at least one hollow region 1 can become a mark on the mobile terminal 100.
The modules or units of the embodiments of the present invention can be combined or separated according to actual requirements.
The foregoing is illustrative of embodiments of the present invention, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the embodiments of the present invention and are intended to be within the scope of the present invention.
Claims (3)
