[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0019] Embodiment. This embodiment provides a wall-mounted speaker 1 that is convenient for disassembly and assembly, including a speaker 1, a connecting plate 2 detachably installed on the back of the speaker 1, and a hanging bracket 3 for hanging the connecting plate 2. A sunken installation hole is provided at the corner position of the hanging bracket 3. As Figure 1 and Figure 2 shown, an expansion bolt is passed through each sunken installation hole and inserted into a preset hole position on the wall to pre-install the hanging bracket 3. In addition, a support spring piece 31 is fixed on the side wall of the hanging bracket 3 away from the hanging support plate 32. The support spring piece 31 is in an arc structure and there is a compression space between it and the hanging bracket 3. As the expansion bolt continuously penetrates into the preset installation hole on the wall, the arc-shaped support spring piece 31 is continuously compressed, making the compression space gradually narrow and generating a rebound potential energy, enhancing the stability of the expansion bolt embedded in the preset installation hole on the wall, that is, ensuring that the hanging bracket 3 is stably installed on the wall.

[0020] A hanging support plate 32 is fixed at the bottom end of the side wall of the hanging bracket 3 facing the connecting plate 2. Both sides of the upper end of the hanging support plate 32 are bent and extended upward to form guiding ends. Guiding notches 34 are provided on the opposite side walls of the two guiding ends. Rolling clamping shafts 23 are rotatably provided at the bottom ends of both side walls of the connecting plate 2. The upper end of the guiding notch 34 bends and extends away from the hanging bracket 3 to form an arc extension part, and the bottom end of the guiding notch 34 is a longitudinally distributed longitudinal guiding part. The upper side wall of the hanging support plate 32 and the side wall of the hanging bracket 3 facing the connecting plate 2 form a limiting side wall that restricts the connecting plate 2 from flipping with the rolling clamping shaft 23 as the rotation center. As Figure 2 shown, first, a hole position aligned with the pre-installation hole groove of the speaker 1 is opened on the connecting plate 2 to facilitate assembly with bolts. In addition, the rolling clamping shaft 23 slides into the upper opening of the arc extension part of the guiding notch 34, the rolling clamping shaft 23 slides along the inside of the arc extension part, and then slides along the inside of the longitudinal guiding part and sits on the inner bottom wall of the longitudinal guiding part. The speaker 1 installed on the side wall of the connecting plate 2 can move synchronously along the movement track of the rolling clamping shaft 23, and finally the connecting plate 2 can be seated on the upper end face of the hanging support plate 32. The hanging support plate 32 serves as a limiting member for the connecting plate 2 to continue moving downward.

[0021] As the rolling card shaft 23 of the connecting plate 2 slides into the inner bottom wall of the longitudinal guiding part along the upper opening of the arc extension part of the guiding notch 34, at this time, the bottom wall of the connecting plate 2 not only sits on the top wall of the hanging support plate 32, but also the side wall of the connecting plate 2 far from the sound box 1 abuts against the side wall of the hanging bracket 3. The side wall of the hanging bracket 3 serves as a limiting member for the connecting plate 2 to rotate and turn around the rolling card shaft 23. As long as the height of the rolling card shaft 23 is not adjusted upward, the sound box 1 can be stably hung on the hanging bracket 3, realizing the rapid assembly of the sound box 1, not easy to tilt or fall. On the contrary, by pulling the rolling card shaft 23 out of the guiding notch 34, it can be quickly disassembled, replaced or repaired. During the entire installation and disassembly process of the sound box 1, there is no need to twist a large number of bolts, greatly improving the installation and disassembly efficiency.

[0022] Furthermore, a through hole opposite to the sunken mounting hole is formed in the supporting elastic piece 31. The width inside the through hole is greater than the aperture of the sunken mounting hole. When the expansion bolt passes through the sunken mounting hole, the bolt can pass through the through hole without any hindrance and be inserted into the preset hole position on the wall.

[0023] In order to further enhance the stability of the connecting plate 2 sitting on the hanging support plate 32, a plug 21 is fixed to the bottom wall of the connecting plate 2, and a jack 33 for inserting the plug 21 is formed on the upper end surface of the hanging support plate 32. As shown in Figure 3 、 Figure 4 and Figure 5 When the connecting plate 2 sits on the top wall of the hanging support plate 32, the plug 21 is inserted into the jack 33. By using the side walls around the plug 21 to abut against the side walls inside the jack 33, the stability of the plug 21 inserted into the jack 33 is enhanced, ensuring that the connecting plate 2 will not turn around the rolling card shaft 23, thereby ensuring that the sound box 1 is stably and vertically hung.

[0024] Moreover, an expansion notch is formed in the bottom wall of the plug 21, and arc-shaped recessed parts are provided on the opposite side walls inside the expansion notch. An expansion rod 35 is fixed to the inner wall of the jack 33. The expansion rod 35 expands the expansion notch and is stuck between the two arc-shaped recessed parts. Without an external force to lift the connecting plate 2 upward, the expansion rod 35 can be stuck between the arc-shaped recessed parts, ensuring that the plug 21 is stably inserted into the jack 33 and preventing the plug 21 from disengaging from the jack 33 accidentally.

[0025] In this embodiment, as shown in Figure 3 and Figure 4As shown in the figure, a U-shaped notch is provided at the upper end of the hanger 3, a wiring hole opposite to the U-shaped notch is provided on the side wall of the connecting plate 2, an I-shaped wire winding rod 22 is fixed on the inner wall of the wiring hole, and the other end of the I-shaped wire winding rod 22 extends into the U-shaped notch. After the speaker 1 is installed on the connecting plate 2, the redundant wires are wound around the outer wall of the I-shaped wire winding rod 22. When the connecting plate 2 is seated on the hanging support plate 32, the end of the I-shaped wire winding rod 22 abuts into the U-shaped notch, preventing the I-shaped wire winding rod 22 from being too long and affecting the fit between the side wall of the connecting plate 2 and the side wall of the hanger 3.

[0026] The specific structure of the speaker 1 refers to the indoor wall-mounted speaker with the model WS-1621. As a prior art, it will not be elaborated here too much.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
