Description

Tablet personal computer structure with four groups of speakers Technical Field The utility model relates to the field of tablet computers, in particular to a tablet computer structure with four groups of speakers. Background In man-machine interaction design of a tablet computer, equipment holding comfort and audio output performance are key factors influencing user experience, and in the existing tablet computer, a loudspeaker is integrated in an edge area of the side edge of the equipment so as to balance internal space layout and acoustic structure requirements; However, when the user holds the device laterally, the palm or finger will naturally cover part of the speaker openings, resulting in a blocked sound wave propagation path, and this shadowing effect will significantly change the sound field distribution characteristics, particularly in terms of high frequency attenuation and volume imbalance, resulting in a reduced audio output quality of the speaker, forcing the user to frequently adjust the holding posture to expose the speaker area, thereby sacrificing the original ergonomic natural holding state. Disclosure of utility model The utility model aims to provide a tablet computer structure with four groups of loudspeakers, which is used for closing the loudspeakers shielded by the hands of a user and simultaneously keeping the audio output function of the loudspeakers which are not shielded so as to ensure the overall sound quality of equipment. The utility model discloses a tablet computer structure with four groups of loudspeakers, which adopts the following technical scheme: Including frame and support, four sound outlets have been seted up on the frame, four the sound outlets are close to four corners of frame respectively, electric connection has first winding displacement on the frame, the outside at the support is established to the frame cover, install the circuit board on the support, first winding displacement and circuit board electric connection, four mounting grooves have been seted up on the support, the mounting groove is close to the sound outlet, be equipped with the second winding displacement in the mounting groove, second winding displacement and circuit board electric connection, install audio mechanism in the mounting groove, audio mechanism includes speaker and contact block, speaker and contact block all are connected with the mounting groove, speaker and circuit board electric connection, contact block and second winding displacement electric contact, the one end of contact block passes the sound outlet, the outside of contact block and the interval between the inner wall of sound outlet have first frame volume. As the preferable scheme, extend in the mounting groove and have the connecting plate, extend on the connecting plate and have the spliced pole, the contact block is connected with the spliced pole, connecting plate and contact block centre gripping second winding displacement. As the preferable scheme, the both sides of mounting groove inner wall all extend there is the stopper, the spacing groove has all been seted up to the both sides of contact block, the stopper top touches the spacing groove. Preferably, a second frame amount is arranged between the connecting plate and the contact block and between the mounting groove and the contact block. As a preferable scheme, a plurality of through holes which are distributed at intervals are formed in the contact block, one end of each through hole is close to the loudspeaker, and the other end of each through hole is close to the outer side of the frame. Preferably, the speaker is electrically connected with a third flat cable, and the third flat cable is electrically connected with the circuit board. As a preferable scheme, a plurality of clamping grooves are formed in the outer side of the support, a plurality of buckles extend from the inner wall of the frame, and the buckles are clamped into the adjacent clamping grooves to be fixed. The tablet computer structure with four groups of speakers has the beneficial effects that: When a user horizontally holds the tablet computer, the micro-current transmitted by the first flat cable is conducted to a contact block in the sound outlet through a hand by a conductive path formed by the contact area of the two hands, and the contact block forms a closed loop detection loop with the circuit board through the second flat cable; Because the first frame volume is arranged between the contact block and the sound outlet at intervals, the structural design allows sound waves generated by the loudspeaker to be diffracted and spread through the first frame volume, and the influence of the contact block on the sound waves transmitted by the sound outlet is reduced.
