[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] Example 1:

[0031] In this embodiment, as Figure 1-5 As shown, the present invention proposes a marine waterproof full-range loudspeaker, including a loudspeaker body 1, a housing 2 below the loudspeaker body, a cover 3 above the loudspeaker body, a hole seat 311 arranged in a circumferential array on the top surface of the cover, a mounting hole 312 at the center of the hole seat, a frame on the top surface of the loudspeaker body, a mounting hole 2 arranged in a circumferential array on the frame, a mounting hole 3 on the top of the housing, and connecting bolts passing through the mounting hole 1, mounting hole 2 and mounting hole 3 in sequence to connect the cover, the loudspeaker body and the housing;

[0032] The side of the housing is provided with a bracket assembly 4, which can install the housing on a fixed part. The bracket assembly includes a connecting shaft 41, an inner clamp 42 and an outer clamp 43. The inner end of the connecting shaft is movably connected to the housing; the inner clamp is connected to the outer end of the connecting shaft; and the outer clamp is bolted to the inner clamp.

[0033] In this example, the speaker frame, mounting hole two, mounting hole three, and connecting bolts are not shown in the figure. This connection structure is a conventional connection structure. The cover and shell can provide external protection for the speaker body. In conjunction with the waterproof treatment of all the internal components of the speaker body, it can improve the speaker body's ability to be waterproof, moisture-proof, and resistant to salt spray corrosion.

[0034] In this example, a pivot is provided at the center of the connecting shaft. The pivot is not shown in the figure. The pivot passes through the housing and is rotatably connected to the housing. This connection structure is a conventional connection structure, that is, the housing can rotate 360 ​​degrees. A limit pin is provided on the side of the connecting shaft. When the limit pin is locked, the housing cannot rotate.

[0035] In this embodiment, the inner clamp is further configured such that stepped grooves 421 and adjustment holes are symmetrically provided at both ends.

[0036] In this embodiment, the outer clamp is further configured such that sockets 431 and adjustment holes 432 are symmetrically provided at both ends of the outer clamp. The sockets correspond to the stepped grooves, and the thickness of the side of the sockets is the same as the depth of the stepped grooves. Adjustment holes 431 and adjustment holes 432 correspond to each other. Adjustment bolts 5 pass through adjustment holes 431 and adjustment holes 432 in sequence to connect the outer clamp and the inner clamp.

[0037] In this example, adjustment hole one is not shown in the figure. Adjustment hole one and adjustment hole two are provided with internal threads. The clamping size between the inner clamp and the outer clamp is adjusted by adjusting the depth of the adjustment bolt inserted into adjustment hole one. The outer clamp is U-shaped as a whole, and the socket cross-section is also U-shaped. When the inner clamp and the outer clamp are connected, the front and back of the inner clamp and the outer clamp are flush.

[0038] In this embodiment, the outer side of the inner clamp is an arc surface one, and the inner side of the outer clamp is an arc surface two, with the curvature of the arc surface two being greater than that of the arc surface.

[0039] In this embodiment, the shell side is further configured to have a circumferential array of grooves 6, with a spacing of 90 degrees between adjacent grooves.

[0040] In this example, one end of the bracket assembly is installed in one of the grooves, and the other end of the bracket assembly is installed on the fastener, which is usually a rod. First, the inner clamp and the housing are attached to the rod, and then the outer clamp is connected to the inner clamp through the adjusting bolt. The depth of the adjusting bolt inserted into the adjusting hole is adjusted according to the rod diameter. In order to facilitate the clamping of the inner and outer clamps, the outer side of the inner clamp and the inner side of the outer clamp are both curved surfaces.

[0041] In this embodiment, the bottom of the housing is further provided with an identification element 7, which is movably connected to the housing. The identification element is movably connected to the housing via a shaft. Regardless of how the housing is fixed, the identification element can be rotated to face the front. The surface of the identification element is printed with a trademark.

[0042] In this embodiment, the cover is further configured to include an outer ring 31, an inner ring 32, and a claw disk 33. The outer ring and the inner ring are connected by claw disks arranged in a circumferential array. The outer ring, the inner ring, and the claw disk are integrally formed, resulting in high structural strength. The spacing between adjacent claw disks is 60 degrees. Since the claw disk and the inner ring protrude from the outer ring and the speaker body, they can protect the speaker body and provide physical protection, while also improving the appearance.

[0043] In this embodiment, the inner ring is further configured with a dust cap 8 in the middle, and the outer ring surface is provided with a hole seat in a circumferential array, the distance between adjacent hole seats is 60 degrees, and the distance between the hole seat and the adjacent claw plate is 30 degrees.

[0044] In this example, the dust cap not only provides dust protection but also optimizes sound diffusion and adjusts timbre, reducing sound concentration in certain directions or creating dead zones. By selecting cover materials with different sound absorption or reflection properties, the high and low frequency components of the sound can be fine-tuned to some extent. For example, it can appropriately absorb some high frequencies to make the sound sound richer, or enhance some low-frequency reflections to make the bass effect fuller.

These terms are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, when terms such as "first" and "second" appear, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In the description of this utility model, it should also be noted that unless otherwise explicitly specified and limited, terms such as "installation," "setting," and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
