DETAILED DESCRIPTION

[0011] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0012] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0013] First, please refer to the appendix. Figure 4 To be continued Figure 6 As shown, the present invention includes: a speaker mount 60, a pair of electrical connecting pieces 70, a magnetic return structure 40, a diaphragm 50, and a voice coil 80. The pair of electrical connecting pieces 70 are attached to the speaker mount 60. The magnetic return structure 40 is attached to the speaker mount 60 and has a magnetic gap 41. The diaphragm 50 is attached to the speaker mount 60. The voice coil 80 is attached to the diaphragm 50 and is located within the magnetic gap 41. A pair of voice coil leads 81 of the voice coil 80 are soldered to the pair of electrical connecting pieces 70. The pair of electrical connecting pieces 70 are also connected to a pair of electronic wires 61 by a piercing means.

[0014] Next, please refer to Figure 4 , Figure 7 , Figure 8 As shown, a pair of electrical connector positioning grooves 62 are formed around the periphery of the speaker base 60. Each electrical connector positioning groove 62 has a first positioning groove 621, a bending groove 622, and a second positioning groove 623. The first positioning groove 621 is located on the first surface of the speaker base 60, and the second positioning groove 623 is located on the second surface of the speaker base 60. The bending groove 622 is located on the side edge of the speaker base 60 and connects the first positioning groove 621 and the second positioning groove 623. The second positioning groove 623 has a long and narrow positioning groove 624 and a wide and flat positioning groove 625. The long and narrow positioning groove 624 connects the wide and flat positioning groove 625 and the bending groove 622. A second vertical piece guide slope 626 is formed on the bottom edge of the wide and flat positioning groove 625, and a positioning lug guide slope 627 is formed on the two outer edges of the long and narrow positioning groove 624.

[0015] Please refer to the following: Figure 8 , Figure 9A , Figure 9BAs shown, the electrical connector 70 has a first electrical connection portion 71, a bending portion 72, and a second electrical connection portion 73. The first electrical connection portion 71 is integrally injection molded into the first positioning groove 621, retaining a solder exposed surface 711. The voice coil leads 81 of the voice coil 80 are soldered to the solder exposed surface 711. The bending portion 72 is accommodated in the bending groove 622 by bending. The second electrical connection portion 73 is positioned in the second positioning groove 623 by bending the bending portion 72. The exposed surface of the second electrical connection portion 73 is formed with a piercing terminal structure 74. The pair of electronic wires 61 are joined to the pierced terminal structure 74 by a piercing means; the second electrical connection portion 73 has a flat sheet 731, a pair of first vertical sheets 741 and a pair of second vertical sheets 742. The flat sheet 731 is connected to the bending portion 72. The pair of first vertical sheets 741 are formed on both sides of the flat sheet 731, and the pair of second vertical sheets 742 are formed on the end edge of the flat sheet 731. The flat sheet 731 and the pair of first vertical sheets 741 are accommodated in the elongated positioning groove 624, and the pair of second vertical sheets 742 are accommodated in the wide and flat positioning groove 625.

[0016] Furthermore, the piercing terminal structure 74 is composed of the pair of first vertical plates 741 with their end faces facing each other and the pair of second vertical plates 742 with their end faces facing each other. The distance between the pairs of piercing claws is slightly smaller than the inner diameter of the outer sheath of the electronic wire 61. When the electronic wire 61 is inserted into the piercing terminal structure 74, the outer sheath of the electronic wire 61 can be pierced by the pairs of piercing claws to form four exposed core wires, so that the core wires can be connected to the electrical connection piece 70. At the same time, in order to ensure that the electronic wire 61 can be clamped by the pairs of piercing claws and not fall off, the two pairs of piercing claws formed by the front and back arrangement of the first vertical plates 741 and the pair of second vertical plates 742 are sufficient to firmly position the electronic wire 61 and prevent it from falling off.

[0017] Furthermore, the two outer edges of the pair of second vertical pieces 742 are tightly fitted and positioned on the two outer edges of the wide and flat positioning groove 625, which can prevent the second electrical connection part 73 from shifting in the Y and Z axes of the icon. The bottom edge of the pair of second vertical pieces 742 is guided by the second vertical piece guide slope 626 and abuts against the bottom edge of the wide and flat positioning groove 625, which can prevent the second electrical connection part 73 from shifting in the X axis of the icon. The two outer edges of the flat piece 731 are also formed with a pair of positioning lugs 732. The pair of positioning lugs 732 are guided by the positioning lug guide slope 627 and tightly fitted and positioned on the narrow positioning groove 624, which can prevent the second electrical connection part 73 from shifting in the Y and Z axes of the icon.

[0018] Based on this configuration, the present invention has a pair of electrical connection piece positioning grooves 62 formed at the periphery of the speaker base 60, and a pair of electrical connection pieces 70 are attached to the electrical connection piece positioning grooves 62. The electrical connection piece 70 is integrally injection molded to attach its first electrical connection portion 71 to the first positioning groove 621 of the electrical connection piece positioning groove 62, while retaining a welding exposed surface 711 for welding electrical connection of the pair of voice coil leads 81 of the voice coil 80. The electrical connection piece 70 is formed by stamping of non-rigid steel sheet, and a temporary positioning piece 75 is also connected to the side of the first electrical connection portion 71 to help integrally injection mold the first electrical connection portion 71 to the speaker base 60. The connection between the electrical connection portion 71 and the temporary positioning piece 75 has a break groove 76. The speaker seat 60 has a retraction groove 63 formed relative to the temporary positioning piece 75. After integral injection molding, the temporary positioning piece 75 is broken off and removed using the break groove 76. Then, the bending portion 72 is bent and accommodated in the bending groove 622. The second electrical connection portion 73 is positioned in the second positioning groove 623 through the bending of the bending portion 72. The exposed surface of the second electrical connection portion 73 has a piercing terminal structure 74, and the pair of electronic wires 61 connected to the outside are joined to the piercing terminal structure 74 by piercing.

[0019] Therefore, the present invention has a piercing terminal structure 74 formed on the pair of electrical connecting pieces 70, so that the pair of electronic wires 61 can be directly connected to the outside through the piercing means. After the pair of electrical connecting pieces 70 is fixed to the speaker base 60 by bending, the piercing terminal structure 74 allows the pair of electronic wires 61 to be connected to the pair of electrical connecting pieces 70 without stripping the outer sheath, tinning, or soldering. The external audio source signal input through the electronic wires 61 can be conducted through the pair of electrical connecting pieces 70 to activate the voice coil 80, so that the speaker can operate and produce sound. Unlike the previous technology, it is not necessary to strip the outer sheath to expose the core wire and then tin it (which is time-consuming and labor-intensive). The previous technology usually requires applying glue to the solder joint to enhance the bonding strength and prevent the electronic wires from detaching from the electrical connecting pieces. The design of the present invention allows the pair of electronic wires 61 to be tightly connected to the pair of electrical connecting pieces 70, so no glue is needed, saving operation time, and enabling the electronic wires to be easily connected through the piercing means.

[0020] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
