Detailed ways

Referring to FIG. 2 , it shows the internal components of the portable electronic device 100 of the present invention, including an outer casing 101 , an outer casing 102 , an inner casing 130 , a speaker 4 , a lens 8 , an antenna base 110 , a first antenna 120 and a circuit board 7 . Both the speaker 4 and the lens 8 are arranged on the circuit board 7 . The inner housing 130 is disposed above the circuit board 7 and has a third opening 131 and a fourth opening 132 thereon, the speaker 4 passes through the third opening 131 , and the lens 8 passes through the fourth opening 132 . The antenna base 110 is provided above the inner case 130 in a locked manner by bolts 115 . The antenna base 110 has a first opening 111 and a second opening 112 , the first opening 111 corresponds to the speaker 4 , and the second opening 112 corresponds to the lens 8 . The first antenna 120 is disposed on the upper surface (first surface) of the antenna base 110 . The inner casing 130, the loudspeaker 4, the lens 8, the antenna base 110, the first antenna 120 and the circuit board 7 are all accommodated in the outer casing 101 and the outer casing 102, and the outer casing 102 is provided with a sound outlet 103, the sound outlet The port 103 corresponds to the speaker 4 .

Referring to FIG. 3 , when the antenna stand 110 is installed on the inner case 130 , the speaker 4 is accommodated in the first opening 111 , and the lens 8 is accommodated in the second opening 112 . Wherein, referring to FIG. 4 a , the lower surface (second surface) of the antenna base 110 is provided with a first continuous wall 113 and a second continuous wall 114 . The first continuous wall 113 surrounds the first opening 111 , and the second continuous wall 114 surrounds the second opening 112 . Referring to Fig. 4b, when assembling the antenna base 110, the first continuous wall 113 is inserted into the gap 133 between the inner wall of the third opening 131 and the speaker 4, thereby fixing the speaker 4, and at the same time, the second continuous wall 114 is inserted into the fourth opening 132 in the gap 134 between the inner wall and the lens 8, thus to fix the lens 8.

The antenna base 110 of the present invention can replace the inner casing of the known technology and provide the function of fixing the speaker 4 and the lens 8 , therefore, the structure of the inner casing can be simplified and the production cost can be reduced. In addition, referring to FIG. 5, since the portable electronic device 100 of the present invention has a first opening 111 and a sound outlet 103 facing the speaker 4, the sound emitted by the speaker 4 can be directly transmitted to the outside of the portable electronic device 100, Thus, the sound raising effect of the speaker 4 is improved.
