In fig. 1, 2, 4 and 6, the detailed features of the first sound outlet 2014 of the first speaker assembly 201 and the detailed features of the second sound outlet 2024 of the second speaker assembly 202 are not shown for convenience.
Referring to fig. 1 to 6, a display device 100 of the present invention includes a display module 10 and a sound-generating module 20.
The display module 10 has a rear case 101, the rear case 101 has a mounting groove 102, the sound generating module 20 is slidably connected in the mounting groove 102, and the size of the mounting groove 102 is matched with the size of the sound generating module 20. Specifically, the sounding assembly 20 includes a first horn assembly 201 and a second horn assembly 202, and the first horn assembly 201 is rotatably connected to the second horn assembly 202.
The sound emitting assembly 20 has two states of use:
as shown in fig. 1, the sound generating assembly 20 is in a first state (or a first using state), the sound generating assembly 20 is located at a first position (e.g., position a shown in fig. 1) in the mounting groove 102, and the sound generating assembly 20 is completely embedded in the mounting groove 102. In the first state, the first speaker assembly 201 and the second speaker assembly 202 emit sound in a first direction (e.g., the X direction shown in fig. 5 and 6), which is opposite to the display direction of the display assembly 10. That is, in the first state, the first speaker assembly 201 and the second speaker assembly 202 both emit sound in a direction away from the display direction of the display assembly 10, i.e., the sound emitting direction of the first speaker assembly 201 and the second speaker assembly 202 is away from the user (rather than facing the user).
As shown in fig. 4, the sound generating assembly 20 is in a second state (or a second using state), the sound generating assembly 20 slides from the first position (e.g., the position a shown in fig. 1) to a second position (e.g., the position B shown in fig. 3) in the mounting groove 102, and the first speaker assembly 201 rotates by a first angle, at this time, the first speaker assembly 201 is exposed on the display surface of the display assembly (i.e., the first speaker assembly 201 is already exposed from the bottom of the display assembly 10, and the user can see the first speaker assembly 201 toward the display surface of the display assembly 10), and the first speaker assembly 201 emits sound along a second direction (e.g., the-X direction shown in fig. 5 and 6), and the second speaker assembly 202 emits sound along the first direction (e.g., the X direction shown in fig. 5 and 6), and the second direction is different from the first direction. In the present embodiment, the second direction is opposite to the first direction, i.e., the first angle is 180 degrees (i.e., in the present embodiment, the first horn element 201 rotates 180 degrees). Thus, in the second state, the sound emitting direction of the first speaker assembly 201 is completely opposite to the sound emitting direction of the second speaker assembly 202, the sound emitting direction of the first speaker assembly 201 is the same as the display direction of the display assembly 10, and the sound emitting direction of the second speaker assembly 202 is opposite to the display direction of the display assembly 10, i.e., the sound emitting direction of the first speaker assembly 201 faces the user, and the sound emitting direction of the second speaker assembly 202 faces away from the user. It should be noted that, in the embodiment, when the sounding element 20 is in the second state, the first speaker element 201 is exposed from the bottom of the display element 10, but not limited thereto, and in other embodiments, the first speaker element 201 may be exposed from the side or the top of the display element 10.
Fig. 7 is a schematic view of the base of the present invention, please refer to fig. 5, fig. 6 and fig. 7, the display device of the present invention further includes a base 30 and a bracket 40, the display element 10 is fixed on the base 30 by the bracket 40, the base 30 is a hollow cavity, the base 30 is provided with a sound outlet 304, and the sound outlet 304 faces a second direction (or the orientation of the sound outlet 304 is the same as the second direction). Specifically, the base 30 includes a cover plate 301 and a bottom plate 302, the cover plate 301 and the bottom plate 302 are disposed in a matching manner, and the sound outlet hole 304 and the hollow cavity can be formed after the cover plate 301 and the bottom plate 302 are combined. The cover plate 301 is provided with a slot 303 and a fixing slot 305, the display device 10 is fixed in the fixing slot 305 of the base 30 by the bracket 40, in the second state, the first speaker assembly 201 is rotated 180 degrees from the first state and inserted into the slot 303 (at this time, the first speaker assembly 201 is hidden in the base 30, and the user cannot observe the first speaker assembly 201 towards the viewing angle of the display surface of the display device 10), so that the base 30 can expand the sound volume of the sound emitted by the first speaker assembly 201 by using the hollow structure therein.
The display device 100 (or the sound generating assembly 20) of the present invention has two use states, and the user can freely switch between the two use states according to his or her own needs. How the display device 100 (or the sounding component 20) is switched from the first state to the second state is described in detail below. Generally, the display device 100 is in the first state (as shown in fig. 1), the sound generating component 20 is entirely located in the mounting groove 102 (i.e. the first speaker component 201 and the second speaker component 202 are both located in the mounting groove 102), at this time, the sound generating component 20 is hidden in the rear shell 101 of the display component 10, the user cannot see the sound generating component 20 when facing the display surface of the display component 10, and the first speaker component 201 and the second speaker component 202 both emit sound along the first direction (as shown in the X direction in fig. 5) (i.e. emit sound away from the display direction). If the user feels that the sound effect cannot meet the use requirement, the user can slide the sound generating component 20 out of the mounting groove 102 (as shown in fig. 2 and 3), so that a part of the sound generating component 20 is exposed from the bottom of the display component 10, and then rotate the first speaker component 201 by 180 degrees (as shown in fig. 4, at this time, the first speaker component 201 is completely exposed from the bottom of the display component 10, and the user can see the first speaker component 201 towards the display surface of the display component 10), so that the first speaker component 201 makes a sound along the second direction (as shown in-X direction in fig. 5) (i.e., the first speaker component 201 makes a sound towards the user), and meanwhile, the second speaker component 202 still keeps making a sound along the first direction (i.e., makes a sound facing away from the display direction). In this way, the user can obtain different auditory sensations.
