Description

Technical Field

[0001] This utility model relates to the field of tablet computers, and more particularly to a tablet computer structure with four sets of speakers. Background Technology

[0002] In the human-computer interaction design of tablet computers, the comfort of holding the device and the audio output performance are key factors affecting the user experience; most existing tablet computers integrate the speakers into the edge area of ​​the side of the device in order to balance the internal space layout and acoustic structure requirements.

[0003] However, when a user holds the device horizontally, the palm or fingers will naturally cover part of the speaker opening, which will obstruct the sound wave propagation path. This masking effect will significantly change the sound field distribution characteristics, specifically manifested as high frequency attenuation and volume imbalance, which will reduce the audio output quality of the speaker and force the user to frequently adjust the holding posture to expose the speaker area, thereby sacrificing the original ergonomic natural holding state. Utility Model Content

[0004] The purpose of this invention is to provide a tablet computer structure with four speakers, which can shut down the speakers covered by the user's hand while maintaining the audio output function of the uncovered speakers, so as to ensure the overall sound quality of the device.

[0005] The technical solution adopted in the tablet computer structure with four sets of speakers disclosed in this utility model is as follows:

[0006] The device includes a frame and a bracket. The frame has four sound outlets, each located near one of the four corners of the frame. A first ribbon cable is electrically connected to the frame. The frame is fitted over the outside of the bracket. A circuit board is mounted on the bracket. The first ribbon cable is electrically connected to the circuit board. The bracket has four mounting slots, each near one of the sound outlets. A second ribbon cable is installed in each mounting slot and electrically connected to the circuit board. An audio mechanism is installed in each mounting slot. The audio mechanism includes a speaker and a contact block. Both the speaker and the contact block are connected to the mounting slots. The speaker is electrically connected to the circuit board. The contact block is electrically in contact with the second ribbon cable. One end of the contact block passes through the sound outlet. A first frame is spaced between the outer side of the contact block and the inner wall of the sound outlet.

[0007] As a preferred embodiment, a connecting plate extends into the mounting groove, a connecting post extends from the connecting plate, the contact block is connected to the connecting post, and the connecting plate and the contact block clamp the second row of cables.

[0008] As a preferred embodiment, limit blocks extend from both sides of the inner wall of the mounting groove, and limit grooves are formed on both sides of the contact block, with the limit blocks touching the limit grooves.

[0009] As a preferred embodiment, a second frame is provided between the connecting plate and the contact block, and between the mounting groove and the contact block.

[0010] As a preferred embodiment, the contact block has multiple through holes arranged at intervals, with one end of each through hole close to the speaker and the other end close to the outer side of the frame.

[0011] As a preferred embodiment, the speaker is electrically connected to a third ribbon cable, which is electrically connected to the circuit board.

[0012] As a preferred embodiment, the bracket has multiple slots on its outer side, and multiple buckles extend from the inner wall of the frame, with the buckles engaging into adjacent slots for fixation.

[0013] The beneficial effects of the tablet computer structure with four sets of speakers disclosed in this utility model are:

[0014] By conducting a microcurrent to the first ribbon cable, when the user holds the tablet horizontally, the conductive path formed by the contact areas of the hands allows the microcurrent transmitted by the first ribbon cable to be conducted through the hand to the contact block inside the sound outlet. This contact block forms a closed-loop detection circuit with the circuit board through the second ribbon cable. The circuit board identifies the position of the blocked sound outlet based on the change in the current path, shuts down the operation of the corresponding speaker in real time, and maintains the output power of other speakers, thereby eliminating the sound field distortion caused by hand obstruction while maintaining the overall audio output.

[0015] Because there is a first frame spacing between the contact block and the sound outlet, this structural design allows the sound waves generated by the speaker to propagate through the first frame diffraction, reducing the impact of the contact block on the sound waves propagating through the sound outlet.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figures 1-3 .

[0025] The present invention discloses a tablet computer structure with four speakers, including a frame 1 and a stand 2.

[0026] In this embodiment, the frame 1 is preferably made of metal to make it conductive; four sound outlets 12 are provided on the outer side of the frame 1, and the sound outlets 12 penetrate the frame 1. In this embodiment, the four sound outlets 12 are preferably located near the four corners of the frame 1. Based on the wide shape of the tablet computer, when the user holds it horizontally, their hands form a selective acoustic shielding area, which only physically shields two of the speakers 31, while the other two speakers 31 located diagonally are always in an open sound field state.

[0027] Furthermore, a first ribbon cable 13 is electrically connected to the frame 1, and one end of the first ribbon cable 13 is electrically connected to the frame 1.

[0028] Furthermore, multiple spaced buckles 111 extend from the inner wall of the frame 1, with the multiple buckles 111 arranged around the center of the frame 1.

[0029] Please refer to Figures 1-7 .

[0030] In this embodiment, the bracket 2 is preferably made of plastic to give it insulation capabilities; a circuit board is mounted on the bracket 2, which is used to control the operation of the tablet computer and audio output; multiple slots 211 are provided on the outer side of the bracket 2, and the multiple slots 211 are arranged around the center of the bracket 2.

[0031] The frame 1 is fitted onto the outside of the bracket 2, and the buckle 111 is fixed in the adjacent slot 211. The other end of the first ribbon cable 13 is electrically connected to the circuit board.

[0032] The bracket 2 has four mounting slots 22. In this embodiment, the four mounting slots 22 are preferably located near the four corners of the bracket 2, so that the four mounting slots 22 are close to the four sound outlets 12. A connecting plate 221 extends into the mounting slot 22. The connecting plate 221 is close to the bottom of the bracket 2. A connecting post 222 extends from the connecting plate 221. In this embodiment, the connecting post 222 is preferably located at the center of the connecting plate 221. Limiting blocks 223 extend from both sides of the inner wall of the mounting slot 22.

[0033] Furthermore, a second cable 321 is provided in the mounting slot 22. One end of the second cable 321 is placed on the connecting plate 221, and the other end of the second cable 321 is electrically connected to the circuit board.

[0034] An audio mechanism 3 is installed in the mounting slot 22. The audio mechanism 3 includes a speaker 31 and a contact block 32. A step is provided on the edge of the mounting slot 22. The step is located at the top of the bracket 2. The speaker 31 and the contact block 32 are both connected to the mounting slot 22. The speaker 31 has hanging ears on both sides. A first screw is provided on the hanging ear. The first screw passes through the hanging ear and is fixedly connected to the bracket 2. The hanging ears of the speaker 31 can be hidden in the step so that when the screen of the tablet computer is installed on the top of the bracket 2, the speaker 31 will not interfere with the screen.

[0035] Furthermore, a third ribbon cable 311 is electrically connected to the speaker 31, and the third ribbon cable 311 is electrically connected to the circuit board.

[0036] Furthermore, in this embodiment, the contact block 32 is preferably made of metal to give it conductivity. The contact block 32 is placed in the mounting groove 22, and a second screw is provided on the contact block 32. The second screw passes through the contact block 32 and is fixedly connected to the connecting post 222. The connecting post 222 will be raised to a certain height, so that the contact block 32 and the connecting plate 221 clamp one end of the second ribbon cable 321, allowing the contact block 32 to make electrical contact with the second ribbon cable 321. In addition, there are second frames between the connecting plate 221 and the contact block 32 and between the mounting groove 22 and the contact block 32. This structural design allows the sound waves generated by the speaker 31 to propagate through diffraction of the second frames, reducing the influence of the contact block 32 on the propagation of sound waves by the speaker 31.

[0037] Furthermore, limit grooves 322 are provided on both sides of the contact block 32, and the limit block 223 abuts against the adjacent limit groove 322; the limit block 223 can limit the contact block 32 within the mounting groove 22, preventing the contact block 32, which is fixed to the connecting plate 221 with only a single second screw, from shifting.

[0038] Furthermore, the contact block 32 is provided with a plurality of spaced through holes 323, which penetrate the contact block 32. One end of the through hole 323 is close to the speaker 31, and the other end of the through hole 323 is close to the outer side of the frame 1. This structural design allows the sound waves generated by the speaker 31 to propagate through the through holes 323 by diffraction, further reducing the influence of the contact block 32 on the propagation of sound waves by the speaker 31.

[0039] One end of the contact block 32 passes through the sound outlet 12, making one end of the contact block 32 flush with the outer side of the frame 1. The other end of the contact block 32 is close to the speaker 31, but there is a certain distance between the contact block 32 and the speaker 31. There is a first frame distance between the outer side of the contact block 32 and the inner wall of the sound outlet 12. This structural design allows the sound waves generated by the speaker 31 to propagate through the diffraction of the first frame distance, reducing the influence of the contact block 32 on the propagation of sound waves in the sound outlet 12.

[0040] First, the circuit board is positioned and installed on the bracket 2. Four speakers 31 are respectively embedded into the four mounting slots 22 of the bracket 2, and an electrical connection is established between the speakers 31 and the circuit board via a third ribbon cable 311. Then, four second ribbon cables 321 are arranged in the four mounting slots 22, with one end of each second ribbon cable 321 resting on the connecting plate 221 and the other end electrically connected to the circuit board. Next, the frame 1 is assembled with the bracket 2. The frame 1 is connected to the bracket 2's slots 211 via clips 111, while the first ribbon cable 311... The other end of 3 is electrically connected to the circuit board; finally, the four contact blocks 32 are placed in the four mounting slots 22 respectively, one end of the contact block 32 is inserted into the sound outlet 12, and after the contact block 32 is snapped between the two limiting blocks 223, the contact block 32 is fixed on the connecting plate 221 by the second screw, and the screen is installed on the top of the bracket 2. The screen covers the mounting slot 22 to form a closed cavity. This design and installation sequence effectively eliminates the interference between the frame 1 and the contact block 32 during the assembly process, and improves the process stability and operational fault tolerance of the equipment assembly.

[0041] When in use, the circuit board conducts a micro current to the frame 1 through the first ribbon cable 13. Since there is a first frame gap between the contact block 32 and the sound outlet 12 of the frame 1, the frame 1 cannot conduct the micro current to the contact block 32 alone. At this time, the contact block 32 is in a de-energized state, and the adjacent speaker 31 operates normally.

[0042] When a user holds the tablet horizontally, when the contact area of ​​both hands is close to the sound outlet 12, the hand guides a micro-current on the frame 1 to the contact block 32. After the circuit board receives the micro-current from the contact block 32 through the second ribbon cable 321, the circuit board identifies the position of the blocked sound outlet 12 based on the change in the current path, and shuts down the operation of the corresponding speaker 31 in real time, while maintaining the output power of other speakers 31, thereby eliminating the sound field distortion caused by hand obstruction while maintaining the overall audio output.

[0043] This invention provides a tablet computer structure with four speakers. By conducting a microcurrent to the first ribbon cable, when the user holds the tablet computer horizontally, the conductive path formed by the contact areas of the hands allows the microcurrent transmitted by the first ribbon cable to be conducted through the hand to the contact block inside the sound outlet. The contact block forms a closed-loop detection circuit with the circuit board through the second ribbon cable. The circuit board identifies the position of the blocked sound outlet based on the change in the current path and shuts down the operation of the corresponding speaker in real time, while maintaining the output power of the other speakers, thereby eliminating the sound field distortion caused by hand obstruction while maintaining the overall audio output.

[0044] Because there is a first frame spacing between the contact block and the sound outlet, this structural design allows the sound waves generated by the speaker to propagate through the first frame diffraction, reducing the impact of the contact block on the sound waves propagating through the sound outlet.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
