After alignment, manually press the protruding spring insertion post 14 of the side sliding strip 5, so that the spring insertion post 14 can be retracted into the elastic cavity 15. At this time, the end face of the spring insertion post 14 is vertical and horizontal with the side face of the side sliding strip 5. At the same time, during the process of the spring insertion post 14 retracting into the elastic cavity 15, it will compress the return spring 17 at its tail end, making the return spring 17 in a compressed state;

[0028] After the spring insertion post 14 retracts into the elastic cavity 15, at this time, the side sliding strip 5 can be slid into the side sliding groove 4, thereby completing the sliding connection work of the first housing 1 and the second housing 2. After the side sliding strip 5 completely slides into the side sliding groove 4, at this time, the elastic insertion post 14 and the plugging hole of the side sliding groove 4 are horizontally aligned. After there is no blockage from the inner wall of the side sliding groove 4, the compressed return spring 17 can be elastically reset, thereby ejecting the spring insertion post 14. The ejected spring insertion post 14 can be inserted into the plugging hole of the side sliding groove 4, thereby completing the sliding positioning plugging effect between the first housing 1 and the second housing 2. The specific state is as shown in the attached Figure 1 figure.

[0029] In this embodiment, support feet 3 are provided on the bottom outer walls of the opposite sides of the first housing 1 and the second housing 2. The support feet 3 are integrally formed with the corresponding housing, so as to facilitate the support work on the desktop during combined use. During actual use, the bottom surface of the support feet 3 can be adhered with an anti-slip cotton pad through glue, which can play a good anti-slip effect on the desktop while having a certain contact buffer, and prevent the audio from slipping off the desktop.

In actual use, the cooperation and insertion of the spring plug post 14 and the insertion hole can effectively improve the connection stability between the first housing 1 and the second housing 2, with high connection strength, stable combined use performance, and good combined use effect. Compared with the existing magnetic attraction structure, the present utility model has a more stable connection effect, the connection is more firm, and the technical problem of the audio being separated due to bumps or drops can be effectively avoided. The connection firmness is strong, and only springs, columns and holes are used for positioning and limiting connection as a whole. The structure is simple, the manufacturing difficulty is low, and it is suitable for popularization and use;

[0040] At the same time, when the front shell 6 and the housing need to be installed, the positioning plug post 13 of the front shell 6 can be aligned with the corresponding positioning post 10, and then manually pressed to insert the positioning plug post 13 of the front shell 6 into the corresponding positioning post 10. At this time, screws can be installed in the positioning post 10 to complete the positioning connection work between the front shell 6 and the housing.
