Details of the first sound outlet 2014 of the first speaker assembly 201 and details of the second sound outlet 2024 of the second speaker assembly 202 are not shown in fig. 1, 2, 4, and 6 for convenience.
Referring to fig. 1 to 6, a display device 100 of the present invention includes a display assembly 10 and a sound generating assembly 20.
The display assembly 10 has a rear housing 101, the rear housing 101 having a mounting slot 102, the sound emitting assembly 20 slidably coupled within the mounting slot 102, the mounting slot 102 sized to match the size of the sound emitting assembly 20. Specifically, the sound emitting assembly 20 includes a first horn assembly 201 and a second horn assembly 202, the first horn assembly 201 being rotatably coupled to the second horn assembly 202.
The sound emitting assembly 20 has two states of use:
as shown in fig. 1, the sounding assembly 20 is in a first state (or first use state), the sounding assembly 20 is located in a first position (a position as shown in fig. 1) in the mounting groove 102, and the sounding assembly 20 is completely embedded in the mounting groove 102. In the first state, the first speaker unit 201 and the second speaker unit 202 emit sound in a first direction (e.g., X direction shown in fig. 5 and 6), which is opposite to the display direction of the display unit 10. That is, in the first state, the first speaker assembly 201 and the second speaker assembly 202 both emit sound away from the display direction of the display assembly 10, i.e., the sound emitting directions of the first speaker assembly 201 and the second speaker assembly 202 are away from the user (rather than facing the user).
As shown in fig. 4, the sounding assembly 20 is in a second state (or second use state), the sounding assembly 20 slides from a first position (a position shown in fig. 1) to a second position (B position 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 exposed from the bottom of the display assembly 10, 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 in a second direction (e.g. -X direction shown in fig. 5 and 6), and the second speaker assembly 202 emits sound in a first direction (e.g. X direction shown in fig. 5 and 6), which is different from the first direction. In this embodiment, the second direction is opposite to the first direction, i.e., the first angle is 180 degrees (i.e., in this embodiment, the first horn assembly 201 is rotated 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, that is, 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 present embodiment, when the sound generating assembly 20 is in the second state, the first speaker assembly 201 is exposed from the bottom of the display assembly 10, but not limited to this, and in other embodiments, the first speaker assembly 201 may be exposed from the side or the top of the display assembly 10.
Fig. 7 is a schematic view of a base of the present invention, and referring 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 assembly 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 faces the same direction as the second direction when the sound outlet 304 is called out). Specifically, the base 30 includes a cover 301 and a bottom plate 302, the cover 301 and the bottom plate 302 are cooperatively disposed, and the cover 301 and the bottom plate 302 can form the sound outlet 304 and the hollow cavity after being combined. The cover 301 is provided with a slot 303 and a fixing slot 305, the display assembly 10 is fixed in the fixing slot 305 of the base 30 by the bracket 40, and 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 assembly 10), so that the base 30 can expand the volume of the sound emitted by the first speaker assembly 201 by using the cavity structure thereof.
The display device 100 (or the sound generating assembly 20) of the present invention has two use states, and a user can freely switch between the two use states according to his/her own needs. The following describes in detail how the display device 100 (or sound emitting assembly 20) switches from the first state to the second state. In general, the display device 100 is in the first state (as shown in fig. 1), the sounding assembly 20 is located in the mounting groove 102 (i.e. the first speaker assembly 201 and the second speaker assembly 202 are located in the mounting groove 102), at this time, the sounding assembly 20 is hidden in the rear housing 101 of the display assembly 10, the user cannot see the sounding assembly 20 when facing the display surface of the display assembly 10, and the first speaker assembly 201 and the second speaker assembly 202 both sound in the first direction (X direction shown in fig. 5) (i.e. sound is emitted back to the display direction). If the user feels that the sound effect of the present case 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 portion 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 emits sound in the second direction (i.e. the first speaker component 201 emits sound towards the user) as shown in the-X direction in fig. 5, and at the same time, the second speaker component 202 still keeps emitting sound in the first direction (i.e. emits sound towards the back display direction). In this way, the user can obtain different auditory sensations.
