[0002] The coaxial speaker uses a coaxial speaker inside, that is, on the same axis, there is a tweeter in addition to a mid-bass speaker, which is responsible for reproducing the treble and mid-bass respectively. The advantage is that the bandwidth of the single speaker is greatly improved, and it is widely used in outdoor and indoor environments with large internal space, such as shopping malls, large conference rooms, etc. Since the coaxial speaker is highly integrated and the sound range of each unit is different, it is easy to interfere with each other, causing noise caused by resonance. In order to solve the above problems, the technical solution of the utility model proposes a coaxial speaker monitoring speaker with strong anti-interference performance, which adopts an anti-interference seat that can be adapted to a variety of speaker shells. It not only has the function of slowing down or even eliminating the noise caused by resonance, but also has the function of changing the size of the installation space, and can be adapted to speakers of various specifications and sizes.

[0030] The specific embodiments of the present utility model are as follows:

[0031] Please see attached Figure 1-Figure 6 ,

[0032] The main structure includes:

[0033] A speaker body 1 having a coaxial speaker unit 10 is installed, and a base assembly 2 is arranged at the bottom of the speaker body 1. The base assembly 2 includes an external frame shell 20 and a wooden skin bottom plate 21 arranged on the bottom surface of the external frame shell 20.

[0034] The wooden skin bottom plate 21 is composed of a wooden board 210 and an externally covered leather layer 211. A bottom cover 23 in contact with the bottom of the speaker body 1 is tightly attached to the wooden skin bottom plate 21, and grooves 24 are provided on both sides. Active plates 25223 for clamping the speaker body 1 are vertically provided on both sides above the bottom cover 23. The active plates 25223 slide on the bottom cover 23 through a sliding assembly 22 and a groove 24 provided on one side of the bottom cover 23.

[0035] Here’s how it works:

[0036] When assembling the speaker body 1 and the base assembly 2, first place the external frame shell 20 in the area to be installed, place the wooden skin bottom plate 21 on the bottom of the external frame shell 20, and then place the bottom cover 23 on top of the wooden skin bottom plate 21, and fix both sides to the sides of the external frame shell 20, align the movable plates 25223 and connecting parts on both sides with the grooves 24 on both sides, and connect the sliding assembly 22 on the other side to the movable plate 25223, and finally place the speaker body 1 on the bottom cover 23.

[0037] When in use, since various types of speakers have different sizes, for example, a smaller speaker can be placed on the bottom cover 23 and fixed by the movable plates 25223 on both sides. For a smaller speaker, when placed on the bottom cover 23, the movable plates 25223 on both sides can be pulled apart before placing the speaker. Therefore, the movable plate 25223 structure can adapt to most speaker structures of different sizes.

[0038] The base assembly 2 with the wooden skin bottom plate 21 can reduce the noise caused by the mutual interference of the units in the coaxial speaker unit 10. Since the wooden board 210 itself has a certain shock absorption effect, it will still generate a certain noise when colliding with other hard objects. Covering the wooden board 210 with a layer of skin 211 (which can be silicone skin or cowhide, etc.) can further reduce or even eliminate the noise, which is most effective for the sound box structure of the coaxial speaker unit 10.

[0039] A preferred embodiment of the utility model: the sliding assembly 22 includes a sliding rod 220 arranged at the bottom of the movable plate 25223, and a slider 222 arranged on the sliding rod and connected to the bottom of the movable plate 25223, a collar 221 is connected to one side of the slider 222, and the collar 221 is sleeved and connected to the sliding rod 220.

[0040] The provided sliding assembly 22 is used for sliding positioning of the movable plate 25 and has a simple structure and is durable.

[0041] A preferred embodiment of a movable plate 25 in the present invention: a through hole 11 for ventilation and heat dissipation is opened on one side of the speaker body 1.

[0042] A preferred embodiment of the present invention is as follows: a back plate 3 is provided on the back of the speaker body 1 , and the bottom of the back plate 3 is connected to the outer frame shell 20 by a clamping block 30 .

[0043] The back panel 3 is used to shield the rear of the speaker from interference, such as impact, and has the function of shielding the wire interface.

[0044] A preferred embodiment of the present invention is as follows: a grid 32 is provided on the back plate 3 for the wires on the back of the speaker body 1 to pass through, and baffles 31 are formed between the grids 32 .

[0045] A preferred embodiment of the present invention: the back plate 3 is an integrated thermoplastic-formed plastic plate structure.

[0046] A preferred embodiment of the present invention is as follows: a sound-absorbing cotton layer is provided between the wooden skin bottom plate 21 and the bottom of the external frame shell 20 .

[0047] The sound-absorbing cotton layer further isolates the noise transmitted from the speaker body 1 to surrounding objects.

[0048] The above description is only a preferred embodiment of the technical solution of the utility model, and does not limit the patent scope of the technical solution of the utility model. All equivalent structural changes made by using the contents of the technical solution description and drawings of the utility model under the conception of the technical solution of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the utility model.
