The flexible circuit board 33 is connected to the lens module connector 21 .

In the known technology, in order to maintain the integrity of the speaker 10 and ensure the speaker effect, a large number of blank areas are left at the contact portion between the speaker 10 and the printed circuit board 20 . In particular, it is not suitable to arrange high components in this blank area, such as global positioning system (Global Positioning System, GSM) connectors, otherwise the speaker 10 will be broken and the speaker effect will be reduced. At the same time, it is not suitable to install electronic components that will affect wireless signal transmission in this blank area, because the position corresponding to the speaker 10 is often the position where the antenna is installed. Therefore, the space on the printed circuit board 20 is wasted.

Detailed ways

FIG. 2a shows an exploded view of the portable electronic device of the present invention. FIG. 2b shows a front view of the portable electronic device of the present invention. Referring to Figures 2a and 2b, the portable electronic device 100 of the present invention includes a housing 110, a printed circuit board 120, a speaker 130, a lens module 140, a foam material 150, and a spring probe connector (pogo pinconnector) 160 and a lens module connector 170.

The housing 110 includes a speaker grid 111, a lens housing grid 112 and a continuous wall 113, the continuous wall 113 surrounds the speaker grid 111, the speaker grid 111 is adjacent to the lens housing grid 112, and the The continuous wall 113 includes a notch 114 .

The printed circuit board 120 includes a speaker area 121 and a lens housing area 122, wherein the speaker area 121 corresponds to the speaker frame 111, the lens housing area 122 corresponds to the lens housing frame 112, and the lens module connector 170 is provided in the above-mentioned speaker area 121 .

The speaker 130 is disposed in the above-mentioned sound box sash 111 . A pogo pin connector 160 is coupled to the speaker 130 and the printed circuit board 120 .

The lens module 140 is disposed in the above-mentioned lens accommodating frame 112 and includes a lens 141 , a circuit board 142 and a flexible circuit board 143 . The lens 141 is disposed on the above-mentioned circuit board 142 , and the above-mentioned circuit board 142 passes through the above-mentioned notch 114 and extends from the above-mentioned lens accommodating frame 112 into the above-mentioned speaker frame 111 . The flexible circuit board 143 is connected to the above-mentioned circuit board 142 , extends in the above-mentioned speaker frame 111 , and is connected to the above-mentioned lens module connector 170 .

The foam material 150 is sandwiched between the continuous wall 113 and the printed circuit board 120 . The above continuous wall 113 is a sound insulation wall.

The shape of the notch 114 matches the shape of the circuit board 142 , thereby closely contacting the circuit board 142 . The continuous wall 113 and the circuit board 142 are covered by the foam material 150 to maintain the integrity of the sound box sash 111 to ensure the sound effect.
