DETAILED DESCRIPTION

[0042] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0043] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0044] Combination Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present disclosure provides a speaker power connection assembly, which includes a speaker body 1 and a mounting shell 2; the speaker body 1 includes a lap spring sheet 11 for power connection, and the lap spring sheet 11 has a lap pin extending outward and tilted away from the speaker body 1; the mounting shell 2 includes an installation station for inserting the lap spring sheet 11, and the installation station has a power connection abutment portion 21 corresponding to the lap pin; wherein, a plating circuit 22 is also laid in the mounting shell 2, and the plating circuit 22 is used to electrically connect the power connection abutment portion 21 with the electronic control mainboard.

[0045] When the speaker power connection assembly is used in specific assembly, the speaker body 1 is first aligned with the installation station in the installation shell 2 in the insertion direction, and the overlapping spring sheet 11 in the speaker body 1 is aligned with the electrical connection abutment part 21 in the installation station in the insertion direction. Then the speaker body 1 is pressed toward the installation station, and the overlapping pins extending outward and tilting in the process will be squeezed by the electrical connection abutment part 21, and will be deformed toward the speaker body 1. When the speaker body 1 is completely pressed and fixed in place in the installation station, the overlapping spring sheet 11 will be tightly abutted with the electrical connection abutment part 21 under the action of its own elastic force, thereby realizing a stable electrical connection between the speaker body 1 and the electrical connection abutment part 21 in the installation shell 2. In addition, since a plating circuit 22 is also laid in the installation shell 2, the plating circuit 22 is used to electrically connect the electrical connection abutment part 21 with the electronic control mainboard. In this way, when the speaker body 1 is inserted and fixed with the installation station in the installation shell 2, the electrical connection between the speaker body 1 and the electronic control mainboard can be simultaneously realized.

[0046] Compared with the prior art in which speakers are electrically connected to the electronic control mainboard through additional wires and power terminals, the speaker power connection assembly provided in the embodiment of the present disclosure can achieve the function of electrical connection with the electronic control mainboard by elastically and tightly abutting the overlapping pins with the power connection abutment part 21 when the speaker body 1 is inserted and fixed to the installation station, thereby omitting the power connection components related to the wires, power terminals and cable organizers, and has the beneficial effects of simple and quick assembly process and the ability to reduce production costs.

[0047] In one possible implementation manner, the overlapping spring sheet 11 has at least overlapping pins extending and tilting in two different directions; the electrical abutment portion 21 is arranged one-to-one with the overlapping pins; wherein, when the overlapping pins are squeezed and abutted against the electrical abutment portion 21, they can be tilted and deformed toward the speaker body 1.

[0048] Specific, combined Figure 3 To further explain in detail, the overlapping pins in the overlapping spring sheet 11 are arranged to extend and tilt in at least two different directions, and the electrical abutment portion 21 is arranged in a one-to-one correspondence with the overlapping pins. In this way, when the speaker body 1 is inserted and fixed in the installation station, the overlapping pins extending and tilting in two different directions will be squeezed and deformed by the electrical abutment portion 21 respectively, so that at least two tightly abutting points are formed between the overlapping spring sheet 11 and the electrical abutment portion 21, thereby further ensuring the electrical abutment stability of the two.

[0049] Furthermore, the two overlapping pins extending and tilting in different directions may be specifically but not limited to be set to be obtuse angles. When they are respectively pressed and abutted by the electrical contacting abutting portion 21 , they may tilt toward the speaker body 1 and deform into right angles or acute angles.

[0050] The specific configuration of the overlapping spring piece 11 has the beneficial effects of simple structure and being able to further improve the electrical contact stability between the overlapping spring piece 11 and the electrical contact portion 21 .

[0051] In one possible implementation manner, the overlapping spring piece 11 is arranged on the installation side wall of the speaker body 1, and the overlapping pin includes a first overlapping pin 111 and a second overlapping pin 112; the first overlapping pin 111 extends outwardly at an acute angle to the installation side wall; the second overlapping pin 112 has a first section 112a connected to the first overlapping pin 111 and parallel to the installation side wall, and a second overlapping section 112b connected to the first section 112a and corresponding to the corner of the installation side wall; wherein the second overlapping section 112b extends outwardly at an obtuse angle to the installation side wall.

[0052] Specific, combined Figure 3For further detailed description, the overlapping pin is specifically set as a first overlapping pin 111 and a second overlapping pin 112 that are connected to each other, and the first body 112a in the second overlapping pin 112 and the first body 112a are connected to form an L shape. By arranging the second overlapping section 112b to extend obliquely outward at an obtuse angle with the mounting side wall, when the overlapping elastic piece 11 abuts and presses against the power connection abutting part 21, the second overlapping section 112b can be tilted and deformed towards the speaker body 1.

[0053] In addition, the first overlapping pin 111 is connected to one end of the first body 112a, and is arranged to be inclined at an acute angle with the mounting side wall of the speaker body 1 in the direction away from the first body 112a. When the overlapping elastic piece 11 abuts and presses against the power connection abutting part 21, the first overlapping pin 111 can also be tilted and deformed towards the speaker body 1.

[0054] The specific setting method of the above overlapping pin has the beneficial effects of simple structure and being able to be electrically connected by abutting and pressing the first overlapping pin 111 and the second overlapping pin 112 against the power connection abutting part 21 during installation and extrusion.

[0055] In an implementable embodiment, raised electrical connection contacts 113 are provided on the sides of the first overlapping pin 111 and the second overlapping pin 112 that face away from the speaker body 1.

[0056] Specifically, in combination with Figure 3 For further detailed description, raised electrical connection contacts 113 are provided on the sides of the first overlapping pin 111 and the second overlapping pin 112 that face away from the speaker body 1. The shape of the above electrical connection contacts 113 can be specifically but not limited to being set as a raised frustum shape, a raised prism shape, etc., and can be processed and formed simultaneously with the first overlapping pin 111 and the second overlapping pin 112 by an integral stamping process.

[0057] By providing the above electrical connection contacts 113, the electrical connection stability when the overlapping elastic piece 11 abuts against the power connection abutting part 21 can be further improved.

[0058] In an implementable embodiment, the speaker body 1 is further provided with a recessed receiving groove 12 at a position corresponding to the second overlapping section 112b; when the second overlapping section 112b abuts and presses against the power connection abutting part 21, it can be at least partially received in the receiving groove 12.

[0059] Specifically, in combination with Figure 3For further detailed description, a sunken receiving groove 12 corresponding to the second overlapping section 112b is formed in the speaker body 1. The specific shape of the receiving groove 12 is the same as that of the second overlapping section 112b, and its size is slightly larger than that of the second overlapping section 112b. In this way, when the second overlapping section 112b abuts against the power connection abutting portion 21 and is tilted and deformed towards the speaker body 1 under extrusion, the second overlapping section 112b can be at least partially received in the receiving groove 12, thus preventing the second overlapping section 112b from being excessively extruded and generating irrecoverable elastic deformation.

[0060] In an implementable embodiment, the power connection abutting portion 21 includes a first abutting portion surface 211 and a second abutting portion surface 212; the first abutting portion surface 211 is arranged parallel to the installation side wall; one end of the second abutting portion surface 212 is connected to the first abutting portion surface 211 and is perpendicular to the first abutting portion surface 211; wherein, when the overlapping elastic sheet 11 is in power connection abutment with the power connection abutting portion 21, the first overlapping pin 111 is docked with the first abutting portion surface 211, and the second overlapping pin 112 is docked with the second abutting portion surface 212.

[0061] Specifically, in combination with Figure 4 For further detailed description, the power connection abutting portion 21 is arranged to have a first abutting portion surface 211 and a second abutting portion surface 212 that are perpendicular to each other. In this way, when the overlapping elastic sheet 11 is in power connection abutment with the power connection abutting portion 21, the first overlapping pin 111 can be extruded by the first abutting portion surface 211 and be in close docking with it, and the second overlapping pin 112 can be extruded by the second abutting portion surface 212 and be in close docking with it, so that the overlapping elastic sheet 11 and the power connection abutting portion 21 form two tightly squeezed contacts with elastic deformation.

[0062] The above specific setting method of the power connection abutting portion 21 has the beneficial effects of simple structure and being able to form tightly squeezed contacts with the two overlapping pins of the overlapping elastic sheet 11 respectively.

[0063] In an implementable embodiment, the installation housing 2 is a plastic housing; a plurality of spaced grooves for laying the electroplating circuit 22 are laser engraved in the installation housing 2.

[0064] Specifically, in combination with Figure 1 and Figure 2 For further detailed description, the installation housing 2 is a plastic housing, and a plurality of spaced grooves for laying the electroplating circuit 22 are laser engraved in the installation housing 2. In this way, the electroplating circuits 22 can be insulated and separated by the plastic installation housing 2, and when the electroplating circuits 22 are laid in the spaced grooves, an insulating layer can be covered on the electroplating circuits 22 to ensure stable insulation between the electroplating circuits 22.

[0065] In an implementable embodiment, the speaker body 1 is further provided with mounting ears 13; the speaker body 1 is fixedly connected to the installation housing 2 through the mounting ears 13.

[0066] Specifically, in combination with Figure 1 and Figure 3 For further detailed description, the above mounting ear 13 can specifically have a clamping plug opening on one side, and is tightly connected to the mounting housing 2 through a double-headed plug, and the mounting ears 13 can be respectively arranged at both ends of the speaker body 1 along the length direction.

[0067] Of course, the above mounting ear 13 can also be set to other connection and installation methods, such as but not limited to screw connection, plug-in plug clamping, etc., as long as the function of stably and tightly connecting to the mounting housing 2 can be achieved.

[0068] In an implementable manner, two speaker bodies 1 are provided; one mounting station is provided on each of the left and right sides of the mounting housing 2; the two speaker bodies 1 can be respectively and independently mounted on the mounting stations.

[0069] Specifically, in combination with Figure 1 For further detailed description, two speaker bodies 1 are provided, and one mounting station is respectively provided on the left and right sides of the mounting housing 2. In this way, the two speaker bodies 1 can be respectively and independently mounted on the mounting stations of the mounting housing 2 in a left-right manner, and the power connection states of the two speaker bodies 1 will not affect each other, and they can be respectively and independently disassembled, assembled and connected to power.

[0070] The above specific installation and setting method of the speaker body 1 has the beneficial effects of simple structure, being able to not affect each other, and being independently disassembled, assembled and connected to power.

[0071] In an implementable manner, the other end of the electroplated circuit 22 is also provided with a protruding plug-in pin; after the mounting housing 2 is installed, the plug-in pin is correspondingly inserted and electrically connected to the electronic control main board.
