detailed description

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

The utility model provides a volume adjustment system of a mobile terminal. The system includes a volume adjustment roller 1 , a roller encoder 2 connected to the volume adjustment roller 1 and a main board 3 electrically connected to the roller encoder 2 . The switch for adjusting the volume is set as a roller structure, and the operation of volume increase and decrease can be performed by rolling the volume adjustment roller 1, and the volume can be quickly changed. Specifically, the volume adjustment roller 1 can drive the roller encoder 2 to rotate, so that the position of the internal components of the roller encoder 2 is adjusted accordingly to generate different signals, and the generated signals are transmitted to the main board 3, thereby realizing the increase or decrease of the sound. decrease.

Specifically, as shown in FIG. 1 , the volume adjusting wheel 1 can be connected to the wheel encoder 2 through a connecting piece 4 , and the connecting piece 4 is located at the center of the volume adjusting wheel 1 . The connecting piece 4 fixes the volume adjustment roller 1 and the roller encoder 2 together to realize the synchronous rotation of the volume adjustment roller 1 and the roller encoder 2 . Wherein, the connecting member 4 may be a screw.

Furthermore, the roller encoder 2 and the main board 3 can be connected through a flexible circuit board 5. The flexible circuit board 5 has the advantages of short assembly time, small size, light weight and thin thickness, and its flexible characteristics can make full use of the internal components of the mobile terminal. Spatially arranged, in this embodiment, the electrical signal output by the roller encoder 2 is transmitted to the main board 3 through the flexible circuit board 5, thereby realizing the adjustment of the volume.

Fig. 2 shows a mobile terminal provided by the present invention, which includes the above-mentioned volume adjustment system. Specifically, as shown in FIGS. 2 to 4, the mobile terminal includes a screen 6 and a rear shell 7, and the volume adjustment wheel 1, the scroll wheel encoder 2 and the main board 3 are arranged in a cavity defined by the screen 6 and the rear shell 7, namely The screen 6 and the rear case 7 form the outer contour of the mobile terminal. A bracket 8 is arranged on the rear shell 7 , and the roller encoder 2 is fixed on the bracket 8 . The bracket 8 fixes the roller 1 and the roller encoder 2 on the rear shell 7 and plays a role of supporting and protecting the roller encoder 2 .
