Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a double-drive loudspeaker structure. Background Art

[0002] The speaker amplifies the sound through vibration, allowing people to hear more atmospheric sound when using it. It is one of the indispensable devices in audio equipment.

[0003] After checking the public announcement number: CN217307867U, a vibration speaker with a dual-drive structure is disclosed. Two cavities are opened on the shell, and a magnetic circuit component and a drive component are installed in each cavity to obtain a vibration speaker with a dual-drive structure.

[0004] However, the dual-drive speaker structure in the above technical solution can only be placed in a targeted manner, with the speaker facing the position where sound amplification is required. However, in actual use, the position of the speaker needs to be adjusted in order to better transmit the sound farther and wider. Therefore, the vibration speaker of the dual-drive structure in the above technical solution cannot achieve the effect of an active speaker. Utility Model Content

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a dual-drive speaker structure, including a shell, a speaker is arranged inside the shell, a back cover is arranged on the back side of the shell, an auxiliary bending mechanism is arranged between the shells, the auxiliary bending mechanism includes a folding sleeve, one end of the folding sleeve is fixedly connected to one of the shells, and the other end of the folding sleeve is fixedly connected to the other shell, and the upper and lower ends of the shell are provided with locking mechanisms, and the locking mechanism is used to fix the bending angle of the shell.

[0007] Furthermore, the locking mechanism includes: a first connecting plate, one end of the first connecting plate is fixed to the upper end of the shell, the connecting end of the first connecting plate is fixedly connected to a threaded rod, the upper end of the other shell is fixedly connected to a second connecting plate, the connecting end of the second connecting plate is sleeved on the threaded rod, and the threaded rod is threadedly connected with a fixing button; a third connecting plate, the third connecting plate is fixed to the lower end of the shell, the connecting end of the third connecting plate is fixedly connected to a rotating rod, the lower end of the other shell is fixed to a fourth connecting plate, and the connecting end of the fourth connecting plate is rotatably arranged on the rotating rod.

[0011] Furthermore, a groove is provided on the upper edge of the fixing button, and there are multiple grooves arranged at equal intervals.

[0012] Compared with the above-mentioned background technology, the dual-drive speaker structure provided by the present application includes a dual-drive speaker with very mature technology today, and an auxiliary bending mechanism as a core component. Its principle relies on that the shells are separately arranged and fixed by folding sleeves. When the shells rotate relative to each other, the folding sleeves are used to limit the rotation and stabilize the rotation angle, and at the same time, the rotation angle of the shells is locked by relying on a locking mechanism.

[0013] The utility model provides a dual-drive speaker structure. Compared with the prior art, it has the following beneficial effects:

[0014] The dual-drive speaker structure provides an auxiliary bending mechanism, and a folding sleeve provided between two shells limits and fixes the rotation angle of the shells. At the same time, the two rotating shells are fixed under the action of a locking mechanism, thereby achieving the effect of stabilizing the shells and preventing vibration from affecting the rotation angle of the shells.
