[0002] Inlaid speakers are speakers that are embedded in the wall. Initially, they were mainly used in public broadcasting and background music systems, and later they were gradually applied to home theaters. The advantage is that they do not affect the overall decoration style, are clean and simple and save space, and are not inferior to the sound effects of traditional home theaters.

[0003] The common installation process of speaker bars on the market is as follows: Step 1: First determine the installation position and height of the speaker bar. Step 2: Use a drill to drill holes and grooves according to the position and height of the speaker bar. Step 3: Insert the speaker bar into the groove and fix it with screws.

[0004] Multiple drilling and grooving complicate the construction process and increase the types of tools used in the installation process. At the same time, multiple drilling and grooving can cause considerable damage to the wall and reduce the aesthetics of the installed speaker bar. Utility Model Content

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] See also Figure 1 to Figure 7 As an embodiment of the utility model, the embedded speaker bar comprises a speaker box body 2, and a speaker cover 1 fixedly mounted on the speaker box body 2;

[0035] A self-fixing mechanism is provided on the speaker box 2, and the speaker box 2 can be fixed on the wall through the self-fixing mechanism;

[0036] The speaker cover 1 is provided with a knob mechanism, and the knob mechanism can drive the self-fixing mechanism to operate.

[0037] In this embodiment, the embedded speaker bar is a speaker bar embedded in a groove opened on the wall. When installing, the speaker bar is first inserted into the groove, and the self-fixing mechanism is driven by the action of the knob mechanism to enable the speaker bar to be firmly embedded in the wall. When replacement or maintenance is required, the self-fixing mechanism can be driven by the knob mechanism to release the connection between the speaker bar and the wall.

[0038] Through the cooperation between the knob mechanism and the self-fixing mechanism, the speaker bar can be installed and removed without the aid of any tools, and will not cause damage to the wall.

[0039] As a further solution of the utility model, the knob mechanism includes a screw rod 3 rotatably mounted on the speaker cover 1, and the screw rod 3 is rotatably mounted on the speaker box 2; an internally threaded sleeve 4 is threadedly connected to the screw rod 3, a third slide groove 401 is provided on the internally threaded sleeve 4, and a limit plate 101 slidably engaged with the third slide groove 401 is fixedly mounted on the speaker cover 1; a knob 301 is fixedly mounted on one end of the screw rod 3.

[0040] In this embodiment, the screw rod 3 is driven to rotate by turning the knob 301. Under the action of the threaded cooperation with the internal threaded sleeve 4 and the limitation of the third slide groove 401 by the limiting plate 101, the internal threaded sleeve 4 will not rotate with the screw rod 3. The internal threaded sleeve 4 will only slide up and down the screw rod 3, so that the limiting plate 101 slides in the third slide groove 401. The action state of the self-fixing mechanism is changed by the up and down sliding of the internal threaded sleeve 4. When the knob 301 stops turning, the action state of the self-fixing mechanism will not be changed by external interference, so that the speaker bar and the wall will not separate after being firmly connected. The action of the self-fixing mechanism can be controlled relatively easily, thereby reducing the difficulty of installation.

[0041] As a further solution of the utility model, the internal threaded sleeve 4 is divided into a cylindrical section and a conical section, and the conical section is close to the bottom surface of the speaker box 2; the conical section cooperates with the self-fixing mechanism.

[0042] In this embodiment, most of the third slide groove 401 is located on the cylindrical section of the internal threaded sleeve 4, so that the limiting plate 101 can better limit the third slide groove 401, thereby limiting the internal threaded sleeve 4 to prevent it from rotating with the screw rod 3;

[0043] The conical section of the internal threaded sleeve 4 is a cone-shaped with a wide upper portion and a narrow lower portion; when it slides toward the base of the speaker box 2, the outer wall will cooperate with the self-fixing mechanism to change its position by continuously squeezing the self-fixing mechanism, thereby changing the action state of the self-fixing mechanism and achieving the purpose of fixing the speaker rod.

[0044] As a further solution of the utility model, the self-fixing mechanism includes a second slide groove 202 provided on the speaker box 2, and a connecting rod 5 is slidably installed in the second slide groove 202; a first slide groove 201 is provided on the speaker box 2, and a protruding column 501 that slidably cooperates with the first slide groove 201 is fixedly installed on the connecting rod 5, and the protruding column 501 cooperates with the conical section of the internal threaded sleeve 4;

[0045] Limit rods 6 are fixedly mounted on both ends of the connecting rod 5 , and a notch 204 for slidingly cooperating with the limit rod 6 is provided on the speaker box 2 .

[0046] In this embodiment, when the internal threaded sleeve 4 slides toward the base of the speaker box 2, the conical section will cooperate with the protruding column 501 and continuously squeeze the protruding column 501, so that the protruding column 501 will slide outward in the first slide groove 201, thereby pushing the connecting rod 5 to slide outward in the second slide groove 202, thereby driving the limiting rod 6 to slide outward in the slot 204.

[0047] The initial position of the limiting rod 6 is in the slot 204. When the limiting rod 6 slides outward, the overall width of the speaker bar will be greater than the width of the groove opened in advance on the wall. After the limiting rod 6 and the inner wall of the groove are continuously squeezed, the friction resistance between the speaker bar and the wall will become very large, and the speaker bar will be firmly fixed and embedded in the wall and cannot be pulled out of the wall at will.

[0048] The embedded connection between the speaker bar and the wall is achieved by the friction force generated by the extrusion of the self-fixing mechanism and the wall, which can reduce further damage to the wall during the installation process and make the installation process more convenient.

[0049] As a further solution of the present invention, the limiting rod 6 is divided into a straight portion and an arc portion, and a plurality of tooth grooves 601 are provided on the arc portion.

[0050] In this embodiment, a deformation gap is formed between the straight part and the curved part. When the curved part is squeezed against the wall, the wall will react to give the curved part a thrust so that it will move closer to the straight part. The deformation gap will be reduced and the elastic force of the limiting rod 6 itself will also increase. The combined effect of the elastic force generated by the deformation of the limiting rod 6 and the squeezing force generated by the increase in the width of the speaker bar can maximize the friction resistance between the speaker bar and the wall, so that the speaker bar can be firmly embedded in the wall.

[0051] After the speaker bar is embedded, the tooth groove 601 will also cooperate with the uneven wall in the groove, making it more difficult to separate the speaker bar from the wall.

[0052] As a further solution of the utility model, a second protrusion 502 is fixedly installed on the connecting rod 5; a first protrusion 203 is fixedly installed in the second sliding groove 202, and a spring 7 is fixedly connected between the first protrusion 203 and the second protrusion 502.

[0053] In this embodiment, the first protrusion 203 of the connecting rod 5 will approach the second protrusion 502 during the outward sliding process, so that the spring 7 is compressed. When the speaker bar needs to be disassembled, the internal threaded sleeve 4 will slide toward the knob 301, so that the conical section and the protruding column 501 are out of contact. At this time, the elastic force of the spring 7 will make the connecting rod 5 slide toward the protruding column 501, so as to drive the limiting rod 6 to be out of the squeezing with the wall, so that the speaker bar can be taken out of the wall; to prevent the limiting rod 6 from being stuck on the wall due to long-term embedding, making it difficult to take it out.

[0054] As a further solution of the present invention, connecting plates are fixedly installed on both ends of the speaker box 2 and both ends of the speaker cover 1.

[0055] In this embodiment, when multiple speaker bars need to be installed in a wall groove, other speaker bars can be connected through the connecting plate.

[0056] As a further solution of the present invention, abutment plates 102 are fixedly mounted on both sides of the speaker cover 1 .

[0057] In this embodiment, in order to prevent the speaker bar from being embedded too deeply into the wall, the abutment plate 102 will contact the wall after the speaker bar is embedded, thereby limiting the speaker bar from being further embedded into the wall.

[0058] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
