[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please refer to Figure 1-6 ;

[0028] A structurally stable loudspeaker system includes a loudspeaker 1, a cabinet 2, and a front cover 3. The cabinet 2 is rectangular, and the front cover 3 is detachably connected to the cabinet 2. In this embodiment, the detachable method of the cabinet 2 and the front cover 3 is not limited. In this embodiment, the cabinet 2 and the front cover 3 can be bolted together. The front cover 3 and the cabinet 2 form a cavity 4 for placing the loudspeaker 1. Specifically, the upper surface of the front cover 3 has a placement position, and the loudspeaker 1 is mounted on the front cover 3. The specific structure of the loudspeaker 1 is as follows: the loudspeaker 1 includes a mounting bracket 11 and a T-shaped iron 12. One end of the mounting bracket 11 is provided with a diaphragm 13. The T-shaped iron 12 is fitted with a magnet 14 and a washer 15 located on the magnet 14. The inner diameters of the magnet 14 and the washer 15 are both... The inner diameter of the mounting bracket 11 is larger than that of the T-iron 12, and the magnet 14 and the washer 15 are fitted on the T-iron 12 to form a magnetic gap. The mounting bracket 11 has a spring 16 inside, which is circular. The inner ring wall of the spring 16 is fixedly connected to the voice coil 17. One end of the voice coil 17 extends into the magnetic gap, and the other end protrudes out of the outer side of the drum 13. It is provided with a dustproof sheet 18 with an arc surface structure. The outer wall of the voice coil 17 is sealed to the drum 13. It is worth noting that the mounting bracket 11 and the front cover 3 are integrally formed. In this embodiment, the mounting bracket 11 and the front cover 3 form a mounting cover 5, that is, the mounting cover 5 can be directly and detachably connected to the cabinet 2, thereby reducing the process of assembling the speaker 1, the front cover 3 and the cabinet 2 by the operator.

[0029] Specifically, when assembling this loudspeaker 1 system, the operator can first install the loudspeaker 1 body, composed of T-iron 12, magnet 14, washer 15, spider 16, voice coil 17, and diaphragm 13, onto the mounting cover 5 in sequence, and then directly connect the mounting cover 5 to the cabinet 2 with bolts. Compared to the traditional method of installing the loudspeaker 1 body and the loudspeaker 1 mounting bracket 11, then connecting the loudspeaker 1 mounting bracket 11 to the front cover 3 with bolts, and then connecting the front cover 3 to the cabinet 2, where the connection between the loudspeaker 1 mounting bracket 11 and the front cover 3 is prone to resonance leading to reduced sound quality, this loudspeaker 1 system reduces assembly steps and increases assembly efficiency. At the same time, the loudspeaker 1 mounting bracket 11 and the front cover 3 of this loudspeaker 1 system are integrally formed, so that the connection between the loudspeaker 1 mounting bracket 11 and the front cover 3 will not resonate, thereby enhancing sound quality.

[0030] In this embodiment, the speaker 1 system provides two installation methods for external installation. The first installation method is as follows: at least one mounting ear 6 is provided at each end of the enclosure 2. In this embodiment, it is preferable that one mounting ear 6 is provided at each end of the enclosure 2. The mounting ear 6 includes a locking hole 61 and a locking cylinder 62. The outer diameter of the two ends of the locking cylinder 62 is larger than the outer diameter of the middle part of the locking cylinder 62, so that the locking cylinder 62 is locked in the locking hole 61. The side wall of the locking cylinder 62 is provided with several through grooves 63, and the length direction of the through grooves 63 is the same as the length direction of the locking cylinder 62. Specifically, when the operator installs the speaker 1 system... When the speaker system is mounted on the wall, it can be installed on the wall by bolts and mounting ears 6, or by suspending the two mounting ears 6 with ropes to fix the speaker system, or by fixing two cylinders on the wall and fitting the snap-fit ​​cylinder 62 onto the two cylinders; the second installation method is as follows: a protrusion is provided on one side of the housing 2, and correspondingly, there is an external worktable to assist in placing the speaker system of this embodiment. The worktable is inclined and has a placement groove for placing the protrusion of the speaker system of this embodiment, so that the protrusion engages with the placement groove, thereby completing the installation of the speaker system.

[0031] In this embodiment, two concave grooves 7 are provided on both sides of the upper end of the box body 2. The two concave grooves 7 are symmetrically arranged. Two snap-fit ​​protrusions 8 are provided on both sides of the lower end of the front cover 3. Correspondingly, the two snap-fit ​​protrusions 8 are also symmetrically arranged. The concave grooves 7 and snap-fit ​​protrusions 8 correspond to each other, so that the concave grooves 7 and snap-fit ​​protrusions 8 snap together. Furthermore, a ring of insertion parts 9 is provided at the upper end of the box body 2. In this embodiment, the bottom of the concave grooves 7 is also provided with insertion parts 9. A ring of insertion grooves 10 is provided on the lower surface of the front cover 3. Correspondingly, the surface of the snap-fit ​​protrusions 8 is also provided with insertion grooves 10. When the operator connects the front cover 3 to the box body 2, the insertion part and the insertion groove 10 are inserted and engaged. On the one hand, this makes the connection surface between the front cover 3 and the box body 2 more neat. On the other hand, it improves the stability of the connection between the front cover 3 and the box body 2.

[0032] In this embodiment, to facilitate the operator in installing the mounting cover 5 onto the enclosure 2, the mounting bracket 11 of the speaker 1 is provided with an alignment bracket 19, which has marking holes 20. Correspondingly, a support beam 21 is provided inside the enclosure 2. The support beam 21 is located inside the enclosure 2 and is fixedly connected to both ends of the inner wall of the enclosure 2. A marking post 22 with a vertical length direction is provided on the support beam 21 facing the front cover 3. The marking post 22 is rectangular in shape, and the diameter of the hole of the marking post 22 is smaller than the inner diameter of the marking hole 20. This allows the operator to fit the hole wall of the marking hole 20 onto the marking post 22 when installing the mounting cover 5 onto the enclosure 2, thereby aligning the mounting cover 5 with the upper end of the enclosure 2. This makes it easier for the operator to assemble the mounting cover 5 and the enclosure 2.

[0033] In this embodiment, to improve the heat dissipation efficiency of the speaker 1 during operation, especially under high power input conditions, a ventilation duct 23 is provided at the lower end of the enclosure 2. One end of the ventilation duct 23 is connected to the outside, and the other end is connected to the cavity 4, which helps to quickly dissipate heat and extend the service life of the speaker 1. To further enhance the wiring connection between the speaker 1 and the outside, a wire hole 24 is provided at the bottom of the enclosure 2. The wall of the wire hole 24 is stepped, allowing the speaker 1 to be connected by a wire.
