Problems solved by technology

[0004] It is precisely in flat devices that these improvements are always ineffective, because the very limited installation height inside the thin speaker makes the height of the electromagnetic speaker strictly limited, usually within tens of millimeters or even ten millimeters, and, The installation and maintenance of this type of speaker is more difficult, because after the thin speaker is sealed, the speaker cannot be inspected and replaced arbitrarily inside.
In this way, the limitations of the general airtight and thin speakers appear in these two aspects, which have become obstacles to the development of speaker systems for this type of flat-panel equipment.

Embodiment 1

[0029] Such as figure 2 As shown, the schematic diagram of this embodiment, figure 1 It is the structure of a general thin speaker, combined with these two pictures for description:

[0030] Such as figure 1 In the fixed structure of the speaker unit of a general thin sound box, the panel 10 and the back panel 20 are parallel to each other, constraining the thickness of the entire sound box body; the panel 10 has an opening 11 that allows the speaker 30 inside the sound cone 35 to emit sound. The back panel 20 is fully enclosed. In order to ensure that the entire sound box can be placed in a thin space with restricted upper and lower thickness, the inner surface 24 of the back panel 20 has been closely attached to the rear end 36 of the speaker 30 and the cone frame 34. It can be seen that the speaker 30 The effective thickness H itself is not greater than the distance from the inner surface 24 of the back plate 20 to the outer surface of the panel 10. Under the premise that the...

Embodiment 2

[0034] Such as image 3 As shown, the schematic diagram of the second embodiment of the present invention. versus figure 2 Compared with the first embodiment shown, the panel 10 part, the cone mouth 35 part of the cone frame 34, and the fixed step edge 22 of the fixing plate 37 and the back plate 20 are all the same; the difference is that the cone frame 34 The rear end 36 is not flush with the back of the fixing plate 37, but has a protruding part that exceeds the thickness X of the back A of the fixing plate 37, which is visible, and figure 1 Compared with the first embodiment shown, the effective thickness H of the speaker in this example can be increased by an increment A. Although the flatness of the bottom surface of the back plate 20 of the entire speaker must be destroyed, it can be allowed in many occasions. The characteristic of this embodiment is that the effective thickness H of the loudspeaker can be maximized according to different occasions, and at the same time,...

Embodiment 3

[0036] Such as image 3 As shown, a schematic diagram of Embodiment 3 of the present invention. versus figure 1 Compared with the illustrated embodiment, the fixed structure of the panel 10 and the speaker is similar. The difference is that the panel 10 and the back panel 20 are no longer parallel but have an inclined feature. This structure is commonly seen on the edge of a desktop flat panel display device; Considering that the entire device is placed vertically against the wall, the entire panel 10 is usually not far from the wall 40 in this case, so it is necessary to make the cone 31 vibrate obliquely so that the sound waves are effective after being reflected by the wall 40 in the direction of the arrow. To enter the listening domain. Therefore, the cone frame 34 is specially designed so that the fixed plate 37 intersects the respective planes of the cone mouth 35. Similarly, the fixed plate 37 allows the speaker 30 to fully expand the effective thickness without being af...

Abstract

The invention discloses a fixed structure of a loudspeaker unit of a thin-type speaker box, comprising a thin-type speaker box body and a loudspeaker arranged inside the speaker box, wherein a panel of the thin-type speaker box body is provided with an opening cooperating with an sound cone of the loudspeaker; a closed back board is installed in the back of the speaker box; a fixed board fixed with a cone frame is installed at rear of the loudspeaker; the area of the fixed board covers the projection of the loudspeaker on the fixed board; the back board is provided with a back board hole for allowing the sound cone to pass through; and seal treatments are performed between the sound cone and the panel, as well as between the fixed board and the back board keep respectively. The technical scheme not only effectively utilizes the thickness of the back board to improve the effective thickness of the loudspeaker, but also greatly facilitates the assembling, maintaining and changing of the loudspeaker unit.

Description

Technical field [0001] The invention relates to a fixing structure applied to a thin sound box speaker unit. Background technique [0002] Digital equipment, multimedia equipment, whether it is home or portable products, the overall trend of tabletization is becoming more and more obvious. Under normal circumstances, such devices have display screens to meet visual multimedia needs. Therefore, the trend of this type of tabletization must target the size of the screen itself as a whole, making all components smaller and smaller. The thinner it comes, so that its appearance will not be much larger than the screen itself. [0003] Under this trend, the structure of electronic components can first be miniaturized and thinner to achieve the goal, but some internal parts and devices of the equipment are very difficult to reduce the size, especially the thinning of a certain scale, the most obvious It is the speaker system of the device. Generally speaking, the effect of simple electro...
