Referring to FIGS. 1 to 4, and FIGS. 12 and 15, when the speakers 42 are not usually used to play sound, the speaker unit 4 is located in the hidden position (FIG. 3, FIG. 4 and FIG. 15), and is located in the speaker space 13, at this time, each pair of clamping arms 542 of the locking groups 51 clamps and fixes the corresponding locking post 45, so that the speaker unit 4 is positioned in the hidden position. When the speakers 42 are to be used to play sound, the speaker unit 4 moves away from the fixing frame 31 and the clamping arms 542 of each locking member 54 are opened to release the corresponding locking post 45, and the corresponding locking post 45 moves along the One direction X1 is spaced apart by a distance, and the positioning group 44 of the speaker unit 4 abuts against the positioning cover 122, so that the speaker unit 4 is positioned in the use position away from the fixing frame 31 and outside the speaker space 13 (FIG. 1 , Figure 2 and Figure 12). Since the speakers 42 are located outside the speaker space 13 when playing sound, the panel 11 of the display device 1 does not need to reserve the sound output area of the speakers 42 of the speaker unit 4, thus achieving both The effect of narrow frame design and speaker sound quality.

8 to 18 show the speaker unit 4 in different positions, one of the locking group 51 and the corresponding locking column 45 of the position changes, the following will organize the views corresponding to each position. It is added that the following positions 1 to 6 are arranged according to the sequence of actions. For example, from the use position (position 1) to the hidden position (position 4), the sequence of actions is position 1 and position 2. , position 3 and position 4, as from the use position (position 1) to the hidden position (position 4), the action sequence is position 4, position 5, position 6 and position 1 in sequence.

When the user finishes using the speakers 42 and wants to move the speaker unit 4 from the use position (position 1) to the hidden position and locate the hidden position (position 4), the user applies force to the speaker unit 4 The housing 41 is moved toward the fixing frame 31. At this time, the locking posts 45 of the housing 41 abut against the corresponding locking piece 54 (position 2), and each locking post 45 moves toward the rotating end 554 It moves and pushes against the bottom convex portion 525 and can rotate relative to the positioning end portion 553 under the action of the bottom convex portion 525 . After that, the rotating end portion 554 of the latching member 55 enters the latching groove 523 from the first groove portion 523a and moves to the positioning groove portion 523c (position 3), when the speaker unit 4 is located at the hidden position (position 4 ). ), the rotating end 554 of the latching member 55 abuts against the valley formed between the first inclined surface 525 a and the third inclined surface 525 c , and the pair of clamping arms 542 are also retracted by the locking shell 52 . The locking post 45 is combined and clamped.

When the user wants to use the speakers 42 to broadcast (the speaker unit 4 is in the hidden position at this time), the user applies force to the housing 41 to make the locking post 45 continue to move toward the fixed frame 31 (position 5). , the latching member 55 passing through the locking member 54 goes upward from the positioning groove portion 523c along the extending direction of the latching groove 523 and abuts against the top convex portion 524 , and the user stops applying force. When the latching member 55, the locking member 54 and the speaker unit 4 are moved downward by gravity, the latching member 55 is moved to the second groove portion 523b by gravity, and is released from the second groove portion 523b. On the contrary, one end of the positioning groove portion 523c is separated from the abutting groove 523 (position 6). The component 54 no longer moves downward, and the speaker unit 4 continues to move downward by gravity. When the speaker unit 4 abuts against the back cover 12, the speaker unit 4 is positioned at the use position (position 1). . Specifically, since the positioning group 44 of the speaker unit 4 is blocked by the positioning cover portion 122 and cannot continue to descend, the speaker unit 4 is positioned at the use position. In addition, during the aforementioned moving process, resistance can also be provided through the buffer group 43 to improve the smoothness of the moving process and prevent the components from being damaged due to excessive speed.

Specifically, referring to FIGS. 19 and 20 , the buffer group 43 includes a buffer block 431 extending from the housing 41 to the locking unit 5 and connected to the damper 32 , and the rotary damper 32 provides the buffer block 431 resistance, thereby decelerating the speaker unit 4 when moving. In this embodiment, the buffer group 43 further includes two buffer columns 432 connected to the housing 41 and located in the receiving groove 411 , and two buffer springs 433 respectively sleeved on the buffer columns 432 . Two ends of each buffer spring 433 along the first direction X1 abut against the shell portion of the housing 41 adjacent to the bottom of the accommodating groove 411 and the fixing frame 31 , respectively. The buffer springs 433 provide a restoring force that constantly moves the speaker unit 4 away from the fixing frame 31 . Specifically, the fixing frame 31 has a back plate 311 connected to the back cover 12 , and a front plate 312 extending from the back plate 311 in a direction opposite to the back cover 12 . The front plate 312 has a first plate portion 313 extending from the upper edge of the back plate 311 and one end of each buffer spring 433 abuts against, and two second plate portions 314 parallel to the first plate portion 313 and symmetrical to each other , and two third plate portions 315 . Each third plate portion 315 is connected to the respective second plate portion 314 and the first plate portion 313 . The damper 32 and the buffer block 431 are disposed between the third plate portions 315 and are substantially located in the center of the fixed frame 31 , and the buffer springs 433 are also disposed symmetrically to the center of the fixed frame 31 , so that the Provides more even cushioning.

In other variations of this embodiment, the first direction X1 may also be parallel to the left and right directions of the drawing, for example, installed on the side of the display device 1 , and further, the locking springs 53 provide constant The locking member 54 is moved away from the locking shell 52 , so that the speaker unit 4 is moved away from the fixing frame 31 and the speaker unit 4 is positioned at the use position. As for restoring the speaker unit 4 to the hidden position, it is the same as the above-mentioned operation method, as long as a force is applied to move the speaker unit 4 toward the fixing frame 31 , the locking post 45 of the speaker unit 4 is subjected to the corresponding locking member 54 . When clamped, the speaker unit 4 is positioned in the hidden position.

To sum up, the present invention has a display assembly with a hidden speaker 42. By arranging the speaker unit 4 that can move between the hidden position and the use position, the panel 11 of the display device 1 does not need to reserve the speaker. The sound output area of the speaker 42 of the unit 4 can indeed achieve the purpose of the present invention.

However, the above are only examples of the present invention, and should not limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
