The touch screen 2 refers to a touch screen display with touch function that integrates the touch screen and the display screen using the Insell method. By embedding touch sensor function inside the display screen, the screen can be made thinner and lighter. Since the battery 3 occupies a large volume, a middle frame 4 is provided between the front shell 1 and the bottom shell 5 for fixing and limiting the installation. In the middle frame 4, a battery mounting window 403 is provided for installing the battery 3, and the control motherboard 6 and the speaker assembly are respectively staggered around the battery 3 to make reasonable and efficient use of the side space of the middle frame 4, effectively avoiding unnecessary thickness problems caused by the installation of the battery 3, control motherboard 6 and speaker assembly. The speaker assembly is connected to the control motherboard 6 via the flexible printed circuit board assembly, and the socket of the flexible printed circuit board assembly is provided with a socket pressure plate 7. The socket pressure plate 7 refers to the metal pressure plate structure of the socket to effectively reduce the floating height caused by the wire (also known as the cable). The flexible printed circuit board refers to FPC, which stands for Flexible Printed Circuit.

[0030] Therefore, this embodiment utilizes the window-like design of the middle frame 4 to effectively achieve staggered installation and fixation of structures such as the battery 3, control motherboard 6, and speaker assembly. The touchscreen 2 is positioned above the battery 3, thus reasonably reducing the thickness of the tablet computer. Furthermore, the speaker assembly and other structures are connected to the control motherboard 6 via a flexible printed circuit board assembly, and the socket of the flexible printed circuit board assembly is equipped with a socket pressure plate 7 to effectively reduce the height caused by the wiring and facilitate product assembly and maintenance. The overall structure of this embodiment is reasonable and efficient, effectively achieving an ultra-thin product effect.

The first socket 601 and the second socket 602 are respectively disposed on different sides of the control motherboard 6 so as to make reasonable use of the different sides of the control motherboard 6 and realize quick plug-in with the first speaker module 8 and the second speaker module 9 respectively, effectively improving the assembly efficiency and space utilization of the product.

[0033] Preferably, in this embodiment, both the first speaker module 8 and the second speaker module 9 are provided with two speakers. Therefore, this embodiment preferably has four speakers, which can well reproduce the 3D stereo effect of the sound quality when playing music and video. The first flexible circuit board 10 is disposed between the two speakers of the first speaker module 8, and the second flexible circuit board 11 is disposed between the two speakers of the second speaker module 9, so that the two speakers of the first speaker module 8 can better share the same first flexible circuit board 10, and the two speakers of the second speaker module 9 can also better share the same second flexible circuit board 11, thereby improving the assembly efficiency and design rationality of the product.
