Therefore, the purpose of further improving the tone quality under the condition that the internal space of the display device is limited can be achieved, and the user experience is improved. In addition, the improvement cost is lower and the realization is easy.

A display device 100 according to an embodiment of the present utility model is described below with reference to fig. 1 to 12.

The display device 100 according to the embodiment of the present utility model may be a display device 100 such as a television, a computer display screen, a conference display screen, or the like. Specifically, the display device 100 may include: the display module, backplate 1, backshell 2 and audio amplifier 3.

Wherein, the display module assembly includes the display screen (not shown), and the display screen can be used for showing image information, and backplate 1 is located the rear side of display screen, and backplate 1 can provide the installation support effect for the display screen. The rear shell 2 is connected with the back plate 1, for example, the rear shell 2 can be connected with the back plate 1 through bolts, and the utility model is not limited to the above, and the connection mode of the rear shell 2 and the back plate 1 can be reasonably selected according to actual needs. The rear housing 2 and the back plate 1 together define a mounting cavity 4 for mounting other devices and components.

The cabinet 3 may include a cabinet 31 and a speaker 32 as sound sources. Wherein the housing 31 is located in the mounting cavity 4, for example, the housing 31 may be located entirely within the mounting cavity 4, or only partially within the mounting cavity 4 and partially outside the mounting cavity 4. The cabinet 31 may be connected to the back plate 1 so as to mount and fix the sound box 3 as a whole.

The speaker 32 is connected with the case 31, for example, the speaker 32 may be clamped with the case 31, connected with a bolt, etc., and the connection mode of the speaker 32 and the case 31 may be selected reasonably according to actual needs.

At least part of the structure of the sound box 3 is embedded in the back plate 1 and/or the rear shell 2. For example, a portion of the speaker 32 that passes out of the case 31 may be embedded in the back plate 1 or the rear case 2, specifically such as: the portion of the speaker 32 that passes out of the front side wall of the case 31 may be embedded in the back plate 1, and the portion of the speaker 32 that passes out of the rear side wall of the case 31 may be embedded in the rear case 2.

In this way, the loudspeaker 32 has a greater mass of air pushed by the diaphragm 323 when the loudspeaker box 3 is in operation. Since the following formula is satisfied between the air mass and the amplitude of the diaphragm 323: m=ρv=ρsx, where ρ is the air density, S is the diaphragm 323 area, and X is the amplitude.

In this way, the bass effect of the display device 100 can be further improved and the user experience can be improved under the condition that the internal space of the display device 100 is limited. In addition, the improvement cost is lower and the realization is easy.

It will be appreciated that the depth of the first avoiding hole 11 may be adapted to the thickness of the magnetic member 321, so that even in the case where the internal space of the display apparatus 100 is limited, a certain space for advancing may be provided for the magnetic member 321 to increase the thickness of the speaker 32, thereby increasing the volume of the internal cavity of the speaker 32 to a certain extent. Thus, when the loudspeaker box 3 works, the air quality pushed by the vibrating diaphragm 323 of the loudspeaker 32 is larger, and the bass sound quality is better.

In some embodiments of the present utility model, the diameter of the first escape aperture 11 is greater than the diameter of the magnetic member 321, and the diameter d1 of the first escape aperture 11 and the diameter d2 of the magnetic member 321 satisfy: d1-d2 is more than or equal to 3mm. That is, the difference between the diameter of the first escape hole 11 and the diameter of the magnetic member 321 is greater than or equal to 3mm, for example, the difference between the diameter of the first escape hole 11 and the diameter of the magnetic member 321 may be 3mm, 3.5mm, 3.8mm, 4mm or more, and it is understood that the difference between the diameter of the first escape hole 11 and the diameter of the magnetic member 321 may be reasonably selected according to practical needs within the above-mentioned range. So, can avoid the vibration transmission of speaker 32 to the display module assembly on, drive backplate 1 even display screen vibration, influence the display effect of display module assembly, also can prevent simultaneously that audio amplifier 3 from damaging.

Thus, on the one hand, the first avoidance hole 11 is used to provide a forward space for the magnetic part 321 of the speaker 32, on the other hand, because the rear side wall of the case 31 is embedded into or penetrates out of the second avoidance hole 21, the distance between the vibrating diaphragm 323 of the speaker 32 and the rear side wall of the case 31 is increased, so that a certain backward space is provided for the vibrating diaphragm 323, and the inner cavity volume of the speaker 32 is increased as a whole, so that the air quality pushed by the vibrating diaphragm 323 of the speaker 32 is higher when the sound box 3 works, and the bass effect is better.

It is to be understood that, when the rear side wall of the case 31 does not protrude from the second escape hole 21 to the outside of the installation cavity 4, the second escape hole 21 may be formed as a through hole penetrating the rear case 2 in the thickness direction of the rear case 2, or may be formed as a groove shape recessed outward from the inner wall of the rear case 2. And when the rear side wall of the case 31 passes through the second escape hole 21, the second escape hole 21 is formed as a through hole penetrating the rear case 2 in the thickness direction of the rear case 2.

That is, the diaphragm 323 may be disposed in the inner cavity of the case 31, and thus, the case 31 may better protect the diaphragm 323. It will be appreciated that in this embodiment, the distance between the diaphragm 323 and the casing 31 may be reasonably adjusted according to actual needs, so that the bass effect of the speaker 32 meets the requirement.

Alternatively, referring to fig. 5 to 12, in still other embodiments of the present utility model, the frame 322 is further penetrated through the rear sidewall of the case 31, such that the diaphragm 323 is positioned at the outer side of the case 31, so that the diaphragm 323 can be inserted into the second escape hole 21, or such that the diaphragm 323 also protrudes to the outer side of the mounting chamber 4. That is, the diaphragm 323 may also protrude from the rear side wall of the case 31 to be inserted into the second escape hole 21 or protrude outside the installation cavity 4. Therefore, the position of the diaphragm 323 can be further moved backwards to increase the volume of the inner cavity of the loudspeaker 32, so that the air quality pushed by the diaphragm 323 of the loudspeaker 32 is higher and the bass effect is better when the loudspeaker box 3 works.
