Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a laptop computer. Background Technology

[0002] With the continuous development of electronic technology, notebook computers have become popular due to their small size and portability, and are now widely used in people's daily lives.

[0003] Like traditional desktop computers, laptops consist of a monitor, keyboard / mouse, processor, memory, and hard drive. However, with the same components, laptops are smaller, lighter, and more portable. Generally speaking, portability is the biggest advantage of laptops over desktop computers. A typical laptop weighs only about 2 kilograms, making it very convenient to carry around for work or travel.

[0004] Existing laptops typically include: a bottom shell, a front shell rotatably connected to the bottom shell, a keyboard and touchpad disposed on the side surface of the bottom shell near the front shell, a display screen disposed on the side surface of the front shell near the bottom shell, a motherboard disposed inside the bottom shell, and components such as a processor and graphics card disposed on the motherboard.

[0005] Laptops typically include an audio module to provide an audio interface for users to plug in headphone or speaker cables, thus offering better audio playback. Current laptop audio modules are soldered onto the motherboard, with an opening in the laptop's metal casing to expose the audio interface for user insertion. Although the design aligns the opening on the metal casing with the audio interface on the motherboard, and vice versa, dimensional tolerances accumulate during actual manufacturing. This results in a significant deviation between the final position of the audio interface and the opening in the metal casing compared to the initial design. Specifically, the tolerance for the metal casing opening position + the dimensional tolerance for its integration with the plastic bracket + the assembly tolerance of the motherboard and plastic bracket + the soldering tolerance of the audio module and motherboard = the final relative position tolerance between the audio interface and the metal casing opening. Therefore, a large relative position tolerance between the final audio interface and the metal casing opening leads to a substantial deviation from the initial design.

[0006] The current approach to solving this misalignment problem is to increase the size of the opening in the metal casing, thereby absorbing the accumulated tolerances and mitigating the positional misalignment. However, this solution inevitably leads to a larger gap between the metal casing opening and the audio interface, affecting aesthetics. Furthermore, it sometimes results in the audio interface not aligning with the metal casing opening, impacting product yield. This problem has been accepted as an industry norm for many years, and no new solutions have been proposed to address it. Summary of the Invention

[0007] The purpose of this utility model is to provide a laptop computer in which the audio module and the motherboard are detachably set. The audio module is assembled onto the motherboard after the audio interface and the shell opening are aligned and positioned. This ensures the fitting accuracy between the audio interface and the shell opening. The shell opening can use the normal design size without enlarging it, thus ensuring a tight fit between the audio interface and the shell opening. Compared with the prior art, this achieves a small gap, making the laptop computer audio interface look beautiful and with a high yield rate.

[0008] To achieve the above objectives, this utility model provides a laptop computer, comprising: a host computer, an audio module electrically connected to the host computer, a mounting bracket for mounting the audio module on the host computer, and a bottom shell mounted on the host computer; the audio module includes an audio interface, a flexible circuit board fixedly connected to the audio interface, and an audio connector disposed on the flexible circuit board, the audio interface having an audio jack for inserting an audio plug; the host computer has a housing and a motherboard mounted inside the housing, the housing having an opening for exposing the audio jack.

[0009] The motherboard has a recess to accommodate an audio interface.

[0010] The main board on both sides of the adjacent groove is provided with threaded holes; the fixing bracket is shaped like a zigzag and has through holes at both ends; the middle of the fixing bracket presses against the audio interface, and two screws pass through the through holes of the fixing bracket and are threaded into the threaded holes of the main board, thereby fixing the audio module on the main board.

[0011] A motherboard connector is provided on the main board near the bottom of the groove. The audio module is electrically connected to the motherboard by docking with the audio connector.

[0012] The fixing bracket is made of a flexible material.

[0013] The fixing bracket is made of rubber.

[0014] The audio interface is connected to the flexible circuit board by welding.

[0015] The motherboard connector and the audio connector are mating board-to-board connectors.

[0016] The outer shell is made of metal.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a laptop computer in which the audio module and the motherboard are detachably set. The motherboard is first assembled with the shell, and the audio module is then assembled onto the motherboard after the audio jack of the audio interface is aligned and positioned with the opening in the shell. This ensures the fitting accuracy between the audio interface and the opening in the shell. The opening in the shell can use the normal design size without enlarging it, thus ensuring a tight fit between the audio interface and the opening in the shell. Compared with the prior art, it achieves a small gap, thereby making the laptop computer audio interface look beautiful and with a high yield rate. Attached Figure Description

[0023] To further illustrate the technical means and effects of this utility model, the following detailed description is provided in conjunction with the preferred embodiments of this utility model and their accompanying drawings.

[0024] Please see Figures 1 to 4 This utility model provides a laptop computer, comprising: a host 2, an audio module 4 electrically connected to the host 2, a mounting bracket 6 for mounting the audio module 4 on the host 2, and a bottom shell 8 mounted on the host 2. The audio module 4 includes an audio interface 40, a flexible circuit board (FPC) 42 fixedly connected to the audio interface 40, and an audio connector 44 disposed on the FPC 42. The audio interface 40 has an audio jack 400 for inserting an audio plug.

[0025] The host 2 has a housing 20 and a motherboard 22 installed inside the housing 20. The housing 20 has an opening 200 to expose an audio jack 400, thereby providing a channel for external connection of the audio interface 40.

[0026] The motherboard 22 has a recess 220 to accommodate the audio interface 40. Threaded holes 222 are provided on both sides of the motherboard 22 adjacent to the recess 220. A motherboard connector 224 is provided on the motherboard 22 adjacent to the bottom of the recess 220. The audio module 4 and the motherboard 22 are electrically connected by mating the motherboard connector 224 with the audio connector 44.

[0027] The mounting bracket 6 is U-shaped, with through holes 60 at both ends. The middle of the mounting bracket 6 presses against the audio interface 40, and two screws 9 pass through the through holes 60 of the mounting bracket 6 and are threaded into the threaded holes 222 of the motherboard 22, thereby mounting the audio module 4 onto the motherboard 22. The mounting bracket 6 is made of a flexible material, such as rubber, and its function is to fix the position of the audio interface 40, not to position the audio interface 40. That is, after the audio jack 400 of the audio interface 40 is aligned with the opening 200 of the outer casing 20, the audio interface 40 is positioned on the motherboard 22, and then the mounting bracket 6 is used to fix the audio interface 40 in this position.

[0028] The audio interface 40 is soldered to the FPC 42. The motherboard connector 224 and the audio connector 44 are mating board-to-board connectors. The housing 20 is made of metal.

[0029] In summary, this utility model provides a laptop computer with a detachable audio module and motherboard. The motherboard is first assembled with the casing, and the audio module is then assembled onto the motherboard after the audio jack of the audio interface is aligned and positioned with the opening in the casing. This ensures the fitting accuracy between the audio interface and the opening in the casing, allowing the opening in the casing to use a normal design size without needing to be enlarged. This ensures a tight fit between the audio interface and the opening in the casing, achieving a smaller gap compared to existing technologies, thus making the laptop computer's audio interface more aesthetically pleasing and with a higher yield rate.
