detailed description

The features and principles of the utility model will be described in detail below in conjunction with the accompanying drawings. The examples given are only used to explain the utility model, and are not intended to limit the protection scope of the utility model.

As shown in FIGS. 1-3 , this embodiment provides a rear case 1 of a display device, which includes a speaker fixing structure 2 for fixing a speaker 3 . The cylinder structure 21 on the ear of the speaker, the two cylinder structures 21 are located on a straight line, and the first end of each cylinder structure 21 is provided with a boss 22 that can be engaged with the ear of the horn 3. The end surface of the boss 22 is a transition surface inclined toward the direction close to the first end.

Through the setting of the speaker fixing structure 2 in this embodiment, when the speaker 3 is assembled, it is only necessary to move the speaker 3 to the preset position, that is, directly above the column structure 21, so that the axis of the column structure 21 is in line with the ear of the speaker 3. on a straight line, and then the horn 3 is moved towards the direction close to the column structure 21, so that the horn 3 is pressed into the column structure 21 through the transition surface on the boss 22, and passes through the boss 22 clamped and fixed to achieve the technical effect of being convenient, efficient, economical, reliable and suitable for automatic assembly of speakers, thus solving the technical problems of cumbersome speaker fixing or unsuitable for automatic assembly.

In this embodiment, the end surface of the boss 22 is a transition surface inclined toward the direction close to the first end, that is, the boss 22 is a barbed structure. Referring to the direction shown in the figure, the boss 22 The cross-sectional area of the upper end is smaller than the cross-sectional area of the lower end.

In this embodiment, as long as the horn 3 is fixed on the rear case 1 of the display device through the horn fixing structure 2, the purpose of preventing the horn 3 from detaching from the column structure 21 is realized, and the cross section of the boss 22 can be a complete ring structure , can also be fan-shaped structure.

Preferably, the cross section of the boss 22 is semicircular.

In this embodiment, the outer peripheral surface of each columnar structure 21 is provided with a positioning plate 23 arranged along the length direction of the corresponding columnar structure 21, and a positioning plate 23 is formed between the positioning plate 23 and the corresponding boss 22. Accommodating space for horn 3 ears.

The positioning plate 23 cooperates with the boss 22 to fix the speaker 3 on the rear case 1 of the display device and prevent the speaker 3 from vibrating too much.

In this embodiment, each of the column structures 21 includes a first side opposite to the other column structure 21, a second side opposite to the other, and a third side installed on the rear case 1 of the display device. and a fourth side opposite to the third side, the positioning plate 23 is provided on the second side and the fourth side.

As shown in Figures 1-3, the fixing of the horn 3 requires a certain space. In order to prevent interference, the positioning plate 23 in this embodiment is not evenly arranged on the outer peripheral surface of the cylindrical structure 21, but is arranged on On the second side and the fourth side of the column structure 21 .

In this embodiment, the loudspeaker fixing structure 2 and the rear case 1 of the display device are integrally injection-molded, saving steps.

This embodiment also provides a display device, including the above-mentioned rear case 1 of the display device, and a speaker 3 fixed to the rear case 1 of the display device. A hollow elastic pad 31 is arranged on the ear of the speaker 3 , and the elastic The pad 31 is sheathed on the column structure 21 through the transition surface, and engaged with the boss 22 .

Through the setting of the speaker fixing structure 2 in this embodiment, when the speaker 3 is assembled, it is only necessary to move the speaker 3 to the preset position, that is, directly above the column structure 21, so that the axis of the column structure 21 is in line with the ear of the speaker 3. on a straight line, and then the horn 3 is moved towards the direction close to the column structure 21, so that the horn 3 is pressed into the column structure 21 through the transition surface on the boss 22, and passes through the boss 22 is clamped and fixed, such a fixing method of the horn 3 is simple and efficient, and is conducive to realizing the automatic installation of the horn 3 .

In this embodiment, the distance between the positioning plate 23 on each of the column structures 21 near the corresponding first end and the corresponding boss 22 is not less than that of the elastic pad 31 thickness.

Preferably, the distance between one end of the positioning plate 23 on each of the column structures 21 close to the corresponding first end and the corresponding boss 22 is equal to the thickness of the elastic pad 31 . Through the elastic fit of the elastic pad 31 , the horn 3 is stably fixed in the accommodation space between the boss 22 and the positioning plate 23 , which plays a role of vibration reduction.

In this embodiment, the ear of the horn 3 is provided with a notch, and the middle part of the elastic pad 31 is provided with a groove that can be clamped on the ear through the notch.

The above is a preferred embodiment of the utility model. It should be noted that, for those skilled in the art, some improvements and modifications can be made without departing from the principle of the utility model. These improvements And wetting should also be regarded as the scope of protection of the present utility model.
