[0030] Embodiment
[0031] As Figures 1 to 7As shown in the figure, a new type of solder tab structure BOX speaker includes a speaker assembly 1, a box upper cover 2, a box lower cover 3, a solder tab 4, and an electronic wire 5. A speaker installation position 31, a solder tab installation position 32, and a wire passing hole 33 are provided inside the box lower cover 3. The solder tab installation position 32 is located on the side of the speaker installation position 31, and a wire passing hole 33 is provided on one side of the box lower cover 3 near the solder tab installation position 32. The speaker assembly 1 includes a speaker magnetic circuit 11 and a speaker bracket 12. The speaker magnetic circuit 11 is embedded inside the speaker bracket 12. The speaker assembly 1 is arranged on the speaker installation position 31. A first speaker pad 121 and a second speaker pad 122 are provided on the speaker bracket 12. The solder tab 4 is arranged on the solder tab installation position 32 and is welded to the first speaker pad 121. The electronic wire 5 passes through the wire passing hole 33 and is connected to the second speaker pad 122 and the solder tab. The box upper cover 2 is covered on the box lower cover 3.
[0032] In the present utility model, two wire passing holes 33 are provided, corresponding to the red wire and the black wire of the electronic wire 5. The red wire and the black wire are respectively connected to the second speaker pad 122 and the solder tab.
[0033] The present utility model adopts a solder tab structure to realize a full-process automated assembly process, improve the welding speed and welding quality. Moreover, the electronic wire 5 does not need to be fixed with glue. The present utility model uses the welding of the solder tab structure and the electronic wire 5 to solve the problems of the electronic wire 5 such as insecure fixation, noise, or wire breakage, and improves the stability performance. Moreover, compared with the traditional method of welding the electronic wire 5, the traditional welding of the electronic wire 5 is prone to generate solder dross, and the BOX speaker will generate noise during operation. The present utility model adopts laser solder ball welding to avoid such defects.
[0034] In this embodiment, please refer to Figure 2 and Figure 3 , a glue sinking groove structure 34 is provided between the speaker installation position 31 and the inner wall of the box lower cover 3. The glue sinking groove structure 34 can improve the waterproofness and airtightness of the BOX speaker.
[0035] In this embodiment, please refer to Figure 6 , a notch one 41 is provided on the inner side of the upper end of the solder tab 4, a notch two 42 is provided on the outer side of the lower end of the solder tab 4, and a reinforcing rib 43 is provided on the outer surface of the solder tab 4 near the notch two 42. The solder tab 4 is made of copper with a tin plating (non-magnetic) to avoid the adsorption of the solder tab 4 and the speaker magnetic circuit 11 during assembly. Among them, the solder tab 4 is designed with a notch one 41 structure, which is convenient for laser solder ball welding and improves the welding effect between the speaker bracket 12 and the solder tab. The solder tab is designed with a notch two 42 structure to prevent the solder tab from conducting heat too fast during the laser solder ball welding process and affecting the welding effect between the wire (black wire) and the solder tab. A reinforcing rib 43 structure is designed at the corresponding position of the notch two 42 to prevent the solder tab 4 from deforming during electroplating, packaging, transportation, and assembly.
[0036] Specifically, please refer to Figure 7 There are two solder joints on the solder tab 4, namely solder joint one 6 and solder joint two 7. Solder joint one 6 is located on notch one 41, and solder joint two 7 is located below notch two 42. Near solder joint two 7, there is a solder joint three 8 on the second speaker pad 122; the solder tab 4 also serves as a guiding function for the first speaker pad 121. Using equipment such as laser solder ball welding, the first speaker pad 121 is welded to the solder tab 4. According to the requirements of the BOX wire outlet position, the first speaker pad 121 (at solder joint one 6) can be guided to the wire outlet (at solder joint two 7); among them, solder joint one 6 is used for welding the first speaker pad 121 to the solder tab 4, solder joint two 7 is used for welding the solder tab 4 to the electronic wire 5 (black wire), and solder joint three 8 is used for welding the second speaker pad 122 to the electronic wire 5 (red wire).
[0037] In this embodiment, the inlet of the wire passing hole 33 is chamfered; this facilitates the insertion of the electronic wire 5; the inner diameter of the wire passing hole 33 is larger than the outer diameter of the electronic wire 5; specifically, when setting, the wire passing hole 33 has a loose fit of 0 - 0.05 mm with the maximum outer diameter of the electronic wire 5, ensuring that the electronic wire 5 can pass through smoothly and is not easily loosened. The position of the wire passing hole 33 is aligned with the position of the second speaker pad 122, ensuring that the wire core of the electronic wire 5 is flat against the center of the second speaker pad 122 and the solder joint two 7 of the solder tab 4 after passing through, ensuring that the solder ball welding is easier to solder and preventing welding deviation / false soldering / missed soldering.
[0038] The present utility model provides a new type of solder tab structure BOX speaker, which is simple in structure and easy to use. By adopting the solder tab 4 structure, a fully automated assembly process can be realized, improving the welding speed and welding quality; and the electronic wire 5 does not need to be fixed with glue. The present utility model uses the solder tab 4 structure to weld with the electronic wire 5 to solve the problems of the electronic wire 5 being not firmly fixed, having hidden troubles such as noise or wire breakage, and improving the stability performance; compared with the traditional way of welding the electronic wire 5, the traditional welding of the electronic wire 5 is prone to generate solder dross, and the BOX speaker will generate noise during operation. The present utility model adopts laser solder ball welding to avoid such defects.
[0039] The above description is a detailed description of the preferred and feasible embodiment of the present utility model, but the embodiment is not used to limit the patent application scope of the present utility model. Any equivalent changes or modifications completed under the technical spirit disclosed by the present utility model should fall within the patent scope covered by the present utility model.
