[0028] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0029] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0030] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0031] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0032] Reference Figure 1-3 The utility model provides a sound box, including a shell 1, a panel 2, a speaker 3 and a diaphragm 4, the panel 2 is fixed to one side of the shell 1, the speaker 3 is fixed on the panel 2, the diaphragm 4 is fixed to the side wall of the shell 1, and electronic components such as a circuit board and an overload protection bubble (not shown in the figure) are fixed in the sound box to transmit electrical signals to the speaker 3 and the diaphragm 4 to complete the conversion of electrical signals and sound signals. It should be understood that the panel 2, the speaker 3, the circuit board and the overload protection bubble are all existing technologies and will not be repeated in this application.

[0033] The diaphragm 4 has a first side 41 and a second side 42 that are arranged opposite to each other, the first side 41 faces the inside of the housing 1, and the second side 42 faces the outside of the housing 1. The surfaces of the diaphragm 4 located at the first side 41 and the second groove are both arc-shaped surfaces, so that the diaphragm 4 is in an arc shape as a whole. The diaphragm 4 in the prior art is usually a planar diaphragm 4. In the same space, the area that the planar diaphragm 4 can provide is limited. The diaphragm 4 in the present application is an arc-shaped diaphragm 4, which can provide a larger diaphragm 4 area in the same space, provide a better low-frequency effect, and enhance the user experience.

[0034] Furthermore, the diaphragm 4 includes an inner ring 44, an outer ring 43 and a connecting ring 45. The inner ring 44 is located between the outer rings 43. The connecting ring 45 is fixed between the inner ring 44 and the outer ring 43. The connecting ring 45 is provided with a U-shaped groove 5 toward the second side 42, thereby providing the diaphragm 4 with a larger vibration stroke and bringing a better low-frequency effect.

[0035] As an embodiment, the speaker in the present application also includes a pressure plate 6, which can be used to stably fix the diaphragm 4 on the side wall of the outer shell 1. The outer shell 1 is provided with a through groove 11 and a receiving groove 12 corresponding to the position of the diaphragm 4. The through groove 11 and the receiving groove 12 are connected. The diaphragm 4 can be placed in the receiving groove 12, and the outer ring 43 can be arranged in the receiving groove 12. The through groove 11 can be used to place the connecting ring 45 to make way for the position of the connecting ring 45.

[0036] Specifically, an annular groove 121 is provided on the bottom surface of the accommodating groove 12, and an edge 122 is formed on the inner side of the accommodating groove 12 by providing the annular groove 121. A clamping groove 431 is provided on the lower side of the outer ring 43, and the lower side of the outer ring 43 can be inserted into the annular groove 121, and the edge 122 can be inserted into the clamping groove 431, so that the diaphragm 4 and the accommodating groove 12 cooperate with each other, so that the diaphragm 4 can be stably placed in the accommodating groove 12.

[0037] There is a gap between the side of the outer ring 43 and the side of the accommodating groove 12. An insert strip 62 is fixed to the lower side of the pressure plate 6. The insert strip 62 can be inserted in the gap, so that the pressure plate 6 can be stably fixed in the accommodating groove 12, and the diaphragm 4 can be pressed in the accommodating groove 12. A groove 61 is opened in the middle of the pressure plate 6, and the protruding inner ring 44 can be located in the groove 61, so that the pressure plate 6 does not compete with the inner ring 44 of the diaphragm 4, so that the pressure plate 6 and the diaphragm 4 can fit more closely and save space.

[0038] The outer shell 1 is a cylindrical outer shell 1, and the pressure plate 6 is an arc-shaped pressure plate 6. The pressure plate 6 can be fixed in the groove 61 by bolts, pressing the outer ring 43 to fix the diaphragm 4, and the outer side of the pressure plate 6 and the outer side of the outer shell 1 are on the same arc surface, so that the pressure plate 6 and the diaphragm 4 do not protrude from the outer shell 1. The structural arrangement is reasonable, and the volume occupied by the speaker is reduced.

[0039] The implementation principle of the utility model is: the diaphragm 4 in the prior art is usually a planar diaphragm 4. In the same space, the area that the planar diaphragm 4 can provide is limited. The diaphragm 4 in the present application is an arc-shaped diaphragm 4, which can provide a larger diaphragm 4 area in the same space, provide better low-frequency effects, and enhance the user experience.

[0040] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0041] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
