Description

Technical Field

[0001] The utility model relates to the field of screen display equipment, in particular to a speaker fixing structure for screen display equipment. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Display devices mainly include all-in-one machines and monitors. Most of these display devices have an external speaker function, which is mainly achieved through speakers. The speakers of existing display devices are mainly located on the left and right sides below the screen, and sound conduction holes are provided below the screen. Due to appearance requirements, the sound conduction holes of the speakers are not allowed to leak out of the front panel. In order to meet this requirement, the speaker settings and fixed positions need to be improved.

[0004] The requirement for the speaker setting position is that the speaker needs to be EMC treated. EMC treatment refers to the ability of a device or system to operate in accordance with the requirements in its electromagnetic environment and not produce intolerable electromagnetic interference to any device in its environment, that is, electromagnetic shielding. The existing speaker EMC treatment mechanism +, designs a metal speaker independent cabin on the inner wall of the sound conduction hole. The inside of the speaker independent cabin only needs to reserve a nut column for fixing the speaker, and the speaker can be fixed horizontally with screws (Note: Before fixing the speaker, a shielding copper mesh needs to be pasted on the inner wall of the sound conduction hole), and then the metal independent cabin cover is fixed with screws to complete the integrated shielding design. However, due to the requirements of appearance, the fixing position of the speaker needs to be improved. The copper mesh plays the role of electromagnetic shielding. Compared with the existing speaker fixing structure, the existing speaker fixing structure can control the height of the speaker and the copper mesh through the display screen fixing structure, that is, the copper mesh can be pressed tightly, but the speaker after the position is changed needs to be attached to the position inside the back shell, and it is different from the traditional structure, so a new speaker fixing structure is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a speaker fixing structure for a display device, which is used to fix the speaker and can perform EMC treatment on the speaker, and through the hierarchical distribution of the L-shaped pressure frame and the fixing frame, the upper and lower levels are increased to avoid interference, effectively utilize the space, and the layout design space is compact, the EMC treatment is effective, and it is safe and reliable.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions:

[0007] A speaker fixing structure for a display device, wherein the fixing structure is arranged on a rear shell of the display device, and a sound conduction hole of the fixing structure is located on the outside of the rear shell of the display device; the fixing structure comprises a fixing chamber, a fixing frame arranged inside the fixing chamber, and a speaker connected to the fixing frame; a diaphragm side of the speaker is close to the sound conduction hole, a copper mesh is arranged between the diaphragm of the speaker and the sound conduction hole, and a pressure frame is arranged between the copper mesh and the speaker.

[0008] The pressing frame is L-shaped and is provided with fixing holes. The fixing position of the pressing frame is lower than the bottom surface of the fixing frame.
