[0028] Embodiment 1:

[0029] like Figure 1-2 As shown, this embodiment provides a directional sound transmission track, including a track seat 11, a positioning sound transmission seat 31 and a plurality of sealing cover plates 21; the sealing cover plates 21 and the positioning sound transmission seat 31 are respectively slidably installed on the track seat 11 longitudinally and transversely, and a plurality of cross bars 111 are longitudinally fixedly installed inside the track seat 11. The sealing cover plates 21 are slidably connected to the cross bars 111, so that the sliding of the sealing cover plates 21 is smoother, and a tightening member 23 is installed between the track seat 11 and the sealing cover plates 21.

[0030] like Figure 4-5 As shown, the two ends of the positioning microphone seat 31 are respectively fixedly mounted with inclined guide arms 32, and the inclined guide arms 32 extend from the end of the positioning microphone seat 31 located on the inner side of the track seat 11 toward the outer side of the track seat 11. The inclined guide arms 32 can abut against the side edge of the sealing cover plate 21.

[0031] like Figure 2 As shown, driving box frames 12 are fixedly installed on both sides of the track seat 11, and driving wheels 14 and motors 13 for controlling the rotation of the driving wheels 14 are installed in the driving box frames 12. A transmission belt 15 is installed between the two driving wheels 14, and a connecting seat is fixedly installed on the side of the transmission belt 15, and the other end of the connecting seat is fixedly connected to the speaker device 1.

[0032] like Figure 3 As shown, the pressing member 23 includes a spring and discs welded to both ends of the spring, and the two discs are detachably fixedly connected to the track seat 11 and the sealing cover plate 21 respectively.

[0033] In order to improve the installation convenience of the top fastener 23, as Figure 1 and Figure 3 As shown, an inspection cover 22 is detachably fixedly installed on the sealing cover plate 21, and the disc close to one side of the sealing cover plate 21 is detachably fixedly connected to the inspection cover 22, so that the installation positions of the discs at both ends of the spring can be accurately aligned.
