[0029] 2000 subwoofer. Detailed Implementation

[0030] Reference Figure 1 As shown, this is a combined speaker provided in an embodiment of the present invention, which includes a column speaker 1000 and a subwoofer 2000. The column speaker 1000 includes multiple (at least two) strip-shaped pieces 100 spliced ​​together in the vertical direction, as shown in the figure. Figure 8As shown, the uppermost strip 100 is the speaker column body, which contains a speaker unit and can emit sound. The speaker column body needs to be electrically connected to the subwoofer 2000 below. Adjacent strips 100 are joined together by a mating structure, and the speaker column 1000 is electrically connected to the subwoofer 2000 via the mating structure, as shown in the diagram. Figure 4 and Figure 5 As shown, the docking structure includes a male connector 104 and a female connector 105. The male connector 104 and the female connector 105 are respectively installed at both ends of the strip 100. The uppermost strip 100 is only fitted with the female connector 105 at its bottom.

[0031] Reference Figures 3 to 5 As shown, for two adjacent strip segments 100, one strip segment 100 has a first mounting hole 101 and a second mounting hole 102, and the other strip segment 100 has a third mounting hole 103. The male connector 104 includes a base plate 106, a mounting post 107, and a male terminal 108. The mounting post 107 and the male terminal 108 are connected to the base plate 106. The side wall of the mounting post 107 is provided with a raised first elastic cantilever 109. The first elastic cantilever 109 can deform. When the first elastic cantilever 109 passes through the first mounting hole 101, it is compressed. The mounting post 107 mates with the first mounting hole 101. The end of the first elastic cantilever 109 abuts against the side wall of one end of the first mounting hole 101, and the base plate 106 abuts against the side wall of the other end of the first mounting hole 101, thereby limiting the male connector 104. The male terminal 108 mates with the second mounting hole 102. The female connector 105 is installed in the third mounting hole 103. The female connector 105 includes a female terminal 110. When the two strips 100 are spliced ​​together, the female terminal 110 and the male terminal 108 are inserted and engaged. The female terminal 110 and the male terminal 108 have metal parts inside, thereby achieving conductivity. The female terminal 110 and the male terminal 108 are also used to connect wires. The side wall of the female terminal 110 is provided with a second elastic cantilever 111 and a limiting boss 112. The second elastic cantilever 111 can deform. When the second elastic cantilever 111 passes through the third mounting hole 103, it is compressed. The second elastic cantilever 111 abuts against the side wall of one end of the third mounting hole 103, and the limiting boss 112 abuts against the side wall of the other end of the third mounting hole 103.

[0032] When splicing two strips 100, the male terminal 108 of the male connector 104 and the female terminal 110 of the female connector 105 can be directly spliced ​​to achieve conductivity. The male connector 104 and the female connector 105 are respectively clamped to the end positions of the two strips 100 by the first elastic arm and the second elastic arm. The installation of the male connector 104 and the female connector 105 does not require the use of screws for fixing, which facilitates the assembly operation.

[0033] It should be noted that the male connector 104 and the female connector 105 can be made of plastic, which makes it relatively easy to manufacture the structure of the first elastic cantilever 109 and the second elastic cantilever 111.

[0034] Reference Figure 3 and Figure 4 As shown, in some embodiments, the female connector 105 is inserted into the third mounting hole 103 from top to bottom. The second elastic cantilever 111 has an L-shaped structure. The lower end of the second elastic cantilever 111 is connected to the side wall of the female terminal 110, and the upper end of the second elastic cantilever 111 is tilted outward. The upper end of the second elastic cantilever 111 can elastically swing relative to the lower end of the second elastic cantilever 111. The upper end of the second elastic cantilever 111 has a protrusion 113, which abuts against the bottom wall of the lower end of the third mounting hole 103. The limiting boss 112 abuts against the bottom wall of the upper end of the third mounting hole 103. This can limit the position of the female connector 105, and after the female connector 105 is installed, it will not move arbitrarily.

[0035] Reference Figure 3 and Figure 4 As shown, in some embodiments, the outer wall of the limiting boss 112 is an inclined wall, and the distance between the inclined wall and the side wall of the female terminal 110 gradually increases in the horizontal direction from top to bottom. It can also be understood that the limiting boss 112 is triangular in shape.

[0036] Reference Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the mounting post 107 is inserted into the first mounting hole 101 from bottom to top, and the first elastic cantilever 109 is inclined. The first elastic cantilever 109 can be understood as an inclined plate. The upper end of the first elastic cantilever 109 is connected to the mounting post 107, and the lower end of the first elastic cantilever 109 is tilted up. The lower end of the first elastic cantilever 109 can elastically swing relative to the upper end of the first elastic cantilever 109.

[0037] Reference Figure 4 As shown, in some embodiments, the upper end of the mounting post 107 is provided with a guide cone surface 114, which can guide the mounting post 107 into the first mounting hole 101. In some embodiments, the mounting post 107 is a hollow structure, thereby reducing the weight of the mounting post 107 and facilitating the machining of the first elastic cantilever 109, which is convenient for demolding.

[0038] Reference Figure 4 As shown, in some embodiments, there are two mounting posts 107, and the male terminal 108 is located between the two mounting posts 107. This arrangement makes the snap-fit ​​connection of the mounting posts 107 more stable. When the male terminal 108 is inserted into the female terminal 110, the first elastic cantilever 109 of the mounting post 107 can remain pressed against the side wall at the upper end of the first mounting hole 101, and it is not easy to deviate.

[0039] Reference Figure 8 As shown, in some embodiments, for two adjacent strips 100, the lower end of the upper strip 100 has a groove 115, and a female connector 105 is located within the groove 115. The upper end of the lower strip 100 has a protrusion 116, which is an annular boss structure. A male connector 104 is located on the protrusion 116, and the protrusion 116 is inserted into the groove 115. Through the cooperation between the protrusion 116 and the groove 115, the strip 100 can be stably kept in a vertical state, providing a positioning effect.

[0040] Reference Figure 9 As shown, in some embodiments, the above-mentioned protrusion 116 structure can also be provided on the top of the subwoofer 2000, and a male connector 104 is arranged in the protrusion 116. The groove 115 at the lower end of the bottom strip 100 can directly cooperate with the protrusion 116, and the female connector 105 in the groove 115 can be plugged into the male connector 104 in the protrusion 116 to achieve a conductive connection.
