The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0054] The following describes in detail Embodiment 1 of this utility model. An example of Embodiment 1 is shown in the accompanying drawings, and will be further described below in conjunction with the drawings. Figure 1-7 The technical solutions in the embodiments of this application will be clearly and completely described.

[0055] This utility model provides a track-type speaker, including a speaker body 1 and a track connection box 2, which is connected to the speaker body 1. The track connection box 2 includes a magnetic component for magnetically connecting to a conductive track 3, a snap-fit ​​component for engaging with the conductive track 3, and a conductive component for contacting and electrically connecting with the conductive track 3. The conductive track 3 includes a track body, a conductive strip disposed on the track body and arranged along the track body's slide direction, a magnetic attraction part for magnetically attracting the track connection box 2, and a snap-fit ​​groove for engaging with the track connection box 2. The track connection box 2 magnetically and snap-fits to the conductive track 3 by the magnetic component attracting the magnetic attraction part and the snap-fit ​​component engaging with the snap-fit ​​groove, and is electrically connected to the conductive track through the conductive component. The conductive component is electrically connected to the speaker body 1, and when the track connection box 2 is connected to the conductive track 3, the conductive track 3 supplies power to the speaker body.

[0056] The weight of the speaker body 1 should be set according to the connection force between the conductive track 3 and the track connecting box 2. It should not be too heavy and is suitable for small speakers.

[0057] The conductive track 3 is surface-mounted at a high location. The conductive track can be either wall-mounted or suspended. First, install the conductive track according to the layout requirements. The conductive strips inside the track are connected to an external power source. The track speaker is physically and electrically connected to the conductive track via a track connector box, making installation and disassembly convenient. The track speaker can be assembled and disassembled by hand, facilitating speaker maintenance and repair. The track speaker is installed at a high location, saving floor space. The track speaker can move along the conductive track, facilitating speaker position adjustment. Suitable track lights can also be installed on the conductive track.

[0058] Specifically, the track body has two conductive grooves along the slide direction, and insulating sleeves are installed in the conductive grooves. Conductive strips are installed in the insulating grooves. In this embodiment, the magnetic attraction part is an iron strip located between the two conductive grooves.

[0059] In this embodiment, the track connection box 2 includes a housing 20 formed by two half-shells connected relative to each other. The conductive component is a conductive spring 21 with elastic conductive protrusions. The conductive spring 21 is arranged on both sides inside the track connection box 2. Conductive openings 201 are provided on both side walls of the track connection box 2. The elastic conductive protrusions extend from the conductive openings 201 to contact the conductive strips of the conductive track 3. The conductive spring 21 is electrically connected to the speaker circuit inside the speaker body 1 through wires.

[0060] The magnetic component is a magnet block 22, which is installed in the track connection box 2. The upper surface of the track connection box 2 is provided with a magnetic opening, and the top of the magnet block 22 protrudes from the magnetic opening so that it can be attracted to the magnetic part of the conductive track 3.

[0061] The snap-fit ​​component includes cantilever hooks 23 located on both sides of the track connection box 2. The two sides of the track connection box 2 are provided with snap-fit ​​openings, and the cantilever hooks 23 are located in the snap-fit ​​openings. The hook heads of the cantilever hooks 23 protrude outward from the snap-fit ​​openings so as to snap-fit ​​with the snap-fit ​​grooves of the conductive track 3.

[0062] The track connector 2 and the speaker body 1 are rotatably connected via a rotating connector 4. A wiring channel is axially provided on the rotating connector 4, through which the wires connecting the conductive parts to the speaker circuit inside the speaker body pass.

[0063] The lower end of the rotating connector 4 is vertically and rotatably connected to the speaker body 1, and the upper end of the rotating connector 4 is horizontally and rotatably connected to the track connecting box 2. By rotating the rotating connector 4 horizontally, the speaker body 1 can be rotated horizontally, thereby achieving the up, down, left, and right rotation adjustment of the speaker body 1.

[0064] The rotating connector 4 includes a first connector 41, a second connector 42, and a connecting rod located between the first connector 41 and the second connector 42. The first connector 41 and the connecting rod are integrally formed. The end of the rotating connector 4 that is horizontally rotatably connected to the speaker body 1 is the first connector 41. The inner cavity of the speaker body 1 is equipped with a hinge seat 5. The first connector 41 is hinged in the hinge seat 5 by a hinge screw, thereby realizing the rotatable connection between the speaker body 1 and the rotating connector 4. Specifically, the hinge seat 5 is U-shaped, and the two sides of the hinge seat 5 are provided with outwardly folded connecting pieces 51. The connecting pieces 51 are provided with connecting holes 52. The upper part of the inner cavity of the rear shell 10 of the speaker body 1 is provided with a connecting post 12 with a threaded hole. The connecting hole 52 is aligned with the threaded hole on the connecting post 12 and connected by screws, so that the hinge seat 5 is connected and fixed in the speaker body 1.

[0065] The first connector 41 is a horizontally placed cylinder. The first connector is placed inside the hinge seat 5. The hinge seat 5 and the first connector 41 are provided with hinge holes. The hinge screw passes through the hinge hole and is locked with a nut, so that the first connector 41 is hinged to the hinge seat 5. The upper rear side of the speaker body 1 is provided with an inverted L-shaped first opening 11 that communicates with the hinge seat 5 and extends through the rear shell 10 of the speaker body. The rotating connector 4 passes through the first opening 11 to realize the vertical rotational connection between the rotating connector 4 and the speaker body 1.

[0066] The end of the rotating connector 4 that is horizontally rotatably connected to the track connecting box 2 is a second connector 42. The second connector 42 includes a rotating head 421 and an extension 422 connected below the rotating head 421. The outer wall of the extension 422 is threaded, and the upper end of the connecting rod is provided with a threaded hole for the extension 422 to be inserted and threadedly connected. The lower part of the track connecting box 2 is provided with a rotating cavity 24 that provides rotation space for the rotating head 421 and a second opening 25 that communicates with the rotating cavity 24 and extends through the lower end face of the track connecting box 2. The rotating head 421 is rotatably disposed in the rotating cavity 24, and the extension 422 protrudes through the second opening 25 and connects to the connecting rod. The diameter of the second opening 25 is smaller than the outer diameter of the rotating head 421, so that the rotating head 421 cannot pass through the second opening 25.

[0067] To prevent the wires inside the rotating connector 4 from twisting due to unrestricted rotation, a rotation limit is provided for the horizontal rotation of the second connector 42. Specifically, a protruding limit block 4211 is provided on the side of the rotating head 421, and a limit block 241 is provided in the rotating cavity 24 to block the limit block 4211. When the rotating head 421 rotates clockwise or counterclockwise until the limit block 4211 contacts the limit block 241, the limit block 4211 and the limit block 241 abut against each other, preventing the rotating head 421 from continuing to rotate clockwise or counterclockwise and limiting the rotation angle.

[0068] like Figure 8-11 As shown, a second embodiment of the present invention is presented. The main difference between this embodiment and the previous embodiment lies in the structure of the track connecting box and the rotation limiting structure of the second connector. In this embodiment, the track connecting box 2 includes a housing 20 with an open upper end and a cover covering the upper opening of the housing 20. Snap-fit ​​openings are provided on both side walls of the housing 20, and cantilever hooks 23 are provided in the snap-fit ​​openings. The hook heads of the cantilever hooks 23 protrude outside the snap-fit ​​openings to snap-fit ​​with the snap-fit ​​grooves of the conductive track 3.

[0069] Conductive spring contacts 21 are arranged on both sides inside the track connection box 2. Conductive openings are provided on both side walls of the track connection box 2. The elastic conductive protrusions 211 of the conductive spring contacts 21 extend from the conductive openings to contact the conductive strips of the conductive track 3. A circuit board 26 is provided inside the track connection box 2, and the conductive spring contacts 21 are electrically connected to the circuit board 26. The circuit board 26 is electrically connected to the speaker circuit inside the speaker body 1 via wires.

[0070] The rotation limiting structure of the second connector is as follows: a gasket 43 is fitted on the protruding part of the second connector 421. The gasket 43 is placed under the rotating head 421. A protruding limiting block three 4211 is provided on the side of the rotating head 421. A limiting block four 431 protrudes upward and outward on the side of the gasket 43. A limiting groove 242 for the limiting block four 431 to rotate is provided at the position adjacent to the side of the rotating cavity 24. The limiting block four 431 extends into the limiting groove 242. When the limiting block four 431 rotates to the end of the limiting groove 242, it abuts against the end of the limiting groove 242. When the limiting block three 4211 rotates to contact the limiting block four 431, the limiting block three 4211 abuts against the limiting block four 431. When the rotating head 421 rotates clockwise or counterclockwise, the limiting blocks 3 4211 and 431 rotate accordingly. When the limiting block 431 rotates to abut against the end of the limiting groove 242, the gasket 43 stops rotating because the limiting block 431 is abutted, but the rotating connector 4 continues to rotate. When the limiting block 3 4211 rotates to abut against the abutted limiting block 431, the rotating connector 4 cannot continue to rotate because the limiting block 3 4211 is abutted, and can only rotate in the opposite direction. Similarly, when it rotates in the opposite direction, it will also be unable to continue to rotate because the limiting blocks 431 and 4211 are abutted, thus achieving the purpose of limiting the rotation angle. Because the limiting block 4 moves within the limiting groove, the rotation angle of the limiting block 3 is greater than 360°.
