[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Combination Figs. 1-3 The loudspeaker shown has a voice coil wire end protection function. Its core component is loudspeaker 1. Loudspeaker 1 is a key carrier, and a protective mechanism 2 is specially set on its side wall to protect its voice coil wire end.

[0026] The basic component of the protection mechanism 2 is the support base plate 201, which is made of high-strength metal and is firmly fixed to the side wall of the speaker 1. The support base plate 201 not only provides a solid and reliable installation foundation for the entire protection mechanism 2, but its reasonable size and shape design also fully considers the coordination with the appearance and internal structure of the speaker 1. Without affecting the overall performance and aesthetics of the speaker 1, it is perfectly integrated into it. Fixing members 202 are installed at both ends of the support base plate 201. The cross-section of the fixing member is a carefully designed "U" shape. This unique structural design not only gives the fixing member 202 excellent structural strength, enabling it to withstand a certain degree of external impact without deformation, but also facilitates the arrangement of subsequent components, reduces overall exposure and installation interference. A clamping assembly 203 is provided above the fixing member 202.

[0027] The clamping assembly 203 is mainly composed of an internally hollow cylindrical sleeve 2031, which facilitates the insertion of the voice coil wire. A flexible clamping piece 2032 is arranged on the inner wall of the sleeve 2031. The flexible clamping piece 2032 is made of soft and elastic rubber or silicone material. A tightening spring 2033 is arranged between the flexible clamping piece 2032 and the inner wall of the sleeve 2031. The tightening spring 2033 provides a continuous and stable tightening force for the flexible clamping piece 2032, so that the flexible clamping piece 2032 can tightly fit the voice coil wire. In addition, a anti-dropping rod 2034 is arranged inside the tightening spring 2033. One end of the anti-dropping rod 2034 is fixed on the flexible clamping piece 2032, and the other end penetrates through the sleeve 2031 and is provided with a limiting piece 2035 at the end. Such a design can not only ensure the normal work of the flexible clamping piece 2032 under the action of the tightening spring 2033, but also effectively prevent the flexible clamping piece 2032 from falling off from the sleeve 2031 due to excessive stress, thereby realizing accurate, stable and safe clamping of the voice coil wire.

[0028] The adjusting piece 204 is installed at the bottom of the fixing piece 202. A guide assembly 205 is further arranged on the adjusting piece 204. The guide assembly 205 mainly includes a rotating rod 2051 rotatably arranged on the adjusting piece 204. An adjusting bolt 2052 for fixing the rotating position of the rotating rod 2051 is arranged on the outer side wall of the adjusting piece 204. A guide piece 2053 is arranged at the end of the rotating rod 2051. A guide groove 2054 is arranged on the guide piece 2053. During the installation of the loudspeaker 1, the installer can adjust the guide groove 2054 to a suitable angle by loosening the adjusting bolt 2052, rotating the rotating rod 2051, and then tightening the adjusting bolt 2052 to fix the position of the rotating rod 2051 according to the direction of the voice coil wire and actual needs. In this way, the guide groove 2054 can provide accurate guidance for the voice coil wire, avoiding the possibility of damage caused by winding and bending of the voice coil wire during operation.

[0029] In order to realize the stable connection with the side wall of the loudspeaker 1, a plurality of threaded holes are accurately arranged on the support bottom plate 201 in this embodiment, so as to ensure accurate correspondence with the pre-set mounting points on the side wall of the loudspeaker 1. The inner wall of the threaded hole is finely tapped. The support bottom plate 201 is connected with the side wall of the loudspeaker 1 through the specially configured fixing bolt. This connection mode not only can withstand certain external impact and vibration, but also can effectively ensure the stability and reliability of the protection mechanism 2 during long-term use, thereby providing continuous and stable protection for the end of the voice coil wire.

[0030] The flexible clamping piece 2032 in the embodiment plays a key clamping and protection role in the whole voice coil wire end protection system, in order to enhance the stable clamping effect on the voice coil wire, anti-skid lines are specially arranged on the surface of the flexible clamping piece 2032, which is an important measure to further improve the clamping performance, the anti-skid lines are in semicircular protrusions, which are arranged on the surface of the flexible clamping piece 2032 in a uniform and regular manner, the shape can provide a larger contact area when contacting the voice coil wire, and meanwhile can form multiple dispersed force points, thereby effectively increasing the friction and providing reliable protection for the voice coil wire end, and reducing the probability of occurrence of faults such as poor contact caused by displacement of the voice coil wire.

[0031] The guiding groove 2054 in the embodiment is in an elliptical shape, which is suitable for voice coil wires of various diameters, and the long axis can provide sufficient space allowance when guiding thick voice coil wires, so as to avoid jamming or extrusion damage of the voice coil wire during the guiding process due to space crowding, and meanwhile, the reasonable size of the short axis can still provide stable and accurate guidance when guiding thin voice coil wires, so as to prevent excessive shaking of the voice coil wire in the guiding groove, and comprehensively ensure the safety and stability of the voice coil wire during the guiding process, thereby providing solid support for effective implementation of the voice coil wire end protection function of the loudspeaker 1.
