[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 5 A speaker module includes a module housing 1, the module housing 1 including a connected plastic shell 11 and a reinforcing steel plate 12, the outer surface of the plastic shell 11 is provided with a wire groove 13, the reinforcing steel plate 12 is provided with a wire clamp 14, and a portion of the wire groove 13 overlaps with the clamping space of the wire clamp 14.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: This speaker module integrates a wire clamp 14 on the reinforcing steel plate 12 and makes the clamping space partially overlap with the wire groove 13 on the outer surface of the plastic shell 11, thereby achieving reliable clamping and fixing of the cable, effectively solving the problem that the cable is easy to detach from the wire groove 13, and significantly improving the positioning stability and vibration resistance; This speaker module makes full use of the rigidity characteristics of the metal parts in the insert injection molding structure, and completes the integration of the wiring fixing function without adding extra parts or thickening the module shell 1, which maximizes the internal cavity space of the module shell 1 to take into account the acoustic performance, and conforms to the trend of thinner and lighter consumer electronics products; Compared with the traditional process, the cable can be pre-positioned along the wire groove 13 and then quickly embedded into the wire clamp 14 by pressing to complete the fixing, which simplifies the assembly process and reduces the use of auxiliary materials such as tape, clips or glue, thereby reducing the complexity of manual or automated assembly.

[0021] Furthermore, the plastic shell 11 is provided with a first window 111, and the wire clamp 14 is provided corresponding to the first window 111.

[0022] As can be seen from the above description, by setting the first window 111 on the plastic shell 11 and making the wire clamp 14 correspond to the window position, the interference of the plastic shell 11 on the clamping action of the wire clamp 14 is avoided, making it easier to observe the assembly status. At the same time, the injection molding difficulty of the plastic shell 11 is reduced, and the overall thinness of the speaker module can be guaranteed.

[0023] Furthermore, the reinforcing steel plate 12 and the wire clamp 14 are integrally formed into a single structure.

[0024] As described above, the steel plate 12 and the wire clamp 14 are integrally formed, which reduces the number of independent parts and assembly processes, eliminates the connection reliability risks of the split structure, and improves the overall structural strength and production efficiency.

[0025] Furthermore, the reinforcing steel plate 12 is provided with a second opening 121, and the wire clamp 14 is located at the second opening 121. The wire clamp 14 is formed by bending a portion of the reinforcing steel plate 12.

[0026] As can be seen from the above description, the second opening 121 is set on the reinforcing steel plate 12 and the wire clamp 14 is formed by partially bending the steel plate. This can be achieved by punching and bending process, which is simple and low cost. The second opening 121 also provides room for the elastic deformation of the clamping arm 141.

[0027] Furthermore, the wire clamp 14 includes a plurality of clamping arms 141, and the clamping space is formed between at least two of the clamping arms 141.

[0028] As described above, multiple clamping arms 141 are used to form a clamping space, creating a multi-point clamping structure, which makes the cable more evenly stressed and significantly improves clamping stability and resistance to vibration and torsion.

[0029] Furthermore, the wire clamp 14 also includes a connecting portion 142, on which the clamping arms 141 are respectively connected to opposite sides.

[0030] As can be seen from the above description, the connecting part 142 connects each clamping arm 141 into one unit, providing a structural base and enhancing the overall rigidity and structural stability of the wire clamp 14.

[0031] Furthermore, at least two of the clamping arms 141 are arranged opposite each other.

[0032] As can be seen from the above description, by arranging at least two clamping arms 141 opposite each other, force can be applied symmetrically from both sides of the cable to prevent the cable from shifting or slipping, thus ensuring the reliability of clamping.

[0033] Furthermore, the number of clamping arms 141 is greater than or equal to three, and the clamping arms 141 on both sides of the connecting part 142 are staggered.

[0034] As can be seen from the above description, using three or more clamping arms 141 arranged in an alternating manner can adapt to cables of different diameters or shapes, expand the applicable range of clamping, and at the same time avoid stress concentration and loose clamping.

[0035] Furthermore, the reinforcing steel plate 12 has a curved portion 122 corresponding to the groove 13.

[0036] As can be seen from the above description, a curved portion 122 corresponding to the wire groove 13 is provided on the reinforcing steel plate 12 so that it can better fit the shape of the plastic shell 11, while enhancing the structural strength of the wire groove 13 area.

[0037] Furthermore, the reinforcing steel plate 12 serves as a grounding plate.

[0038] As can be seen from the above description, configuring the reinforcing steel plate 12 as a grounding plate integrates the mechanical reinforcement function and the electromagnetic shielding grounding function; the wire clamp 14 makes contact with the cable and conducts electricity, realizing the grounding of the outer surface of the cable.

[0039] Please refer to Figures 1 to 5 One embodiment of this utility model is a speaker module that can be installed in various electronic devices such as mobile phones, laptops, smartwatches, and smart glasses.

[0040] The speaker module includes a module housing 1 and a speaker unit disposed within the module housing 1. The module housing 1 includes a connected plastic shell 11 and a reinforcing steel plate 12. Due to the presence of the reinforcing steel plate 12, the thickness of the plastic shell 11 can be made thinner while maintaining the same structural strength, thereby leaving more space inside the module housing 1. The outer surface of the plastic shell 11 is provided with a wire groove 13, and the reinforcing steel plate 12 is provided with a wire clamp 14. A portion of the wire groove 13 overlaps with the clamping space of the wire clamp 14.

[0042] The plastic shell 11 is provided with a first window 111, and the wire clamp 14 is provided corresponding to the first window 111.

[0043] The reinforcing steel plate 12 and the wire clamp 14 are integrally formed. The reinforcing steel plate 12 is provided with a second opening 121 corresponding to the first opening 111, that is, the first opening 111 and the first opening 111 overlap at least partially. The wire clamp 14 is located at the second opening 121 and is formed by bending a part of the reinforcing steel plate 12.

[0044] Specifically, the wire clamp 14 includes a plurality of clamping arms 141, and at least two of the clamping arms 141 form the clamping space. The wire clamp 14 also includes a connecting portion 142, on which the clamping arms 141 are respectively connected to opposite sides of the connecting portion 142.

[0045] In some embodiments, at least two of the clamping arms 141 are arranged opposite each other. In other embodiments, the number of clamping arms 141 is greater than or equal to three, and the clamping arms 141 on both sides of the connecting portion 142 are staggered, which makes it easier to insert the cable.

[0046] The reinforcing steel plate 12 has a curved portion 122 corresponding to the groove 13.

[0047] In some embodiments, the reinforcing steel plate 12 is a grounding plate, and the reinforcing steel plate 12 grounds the outer surface of the outgoing cable 2 or the connecting cable through the wire clamp 14.
