[0022] Figure 2 This is a schematic diagram of the local structure of the utility model Figure 2 . DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] A ceiling speaker for suppressing cabinet resonance, comprising

[0025] The bottom shell 1 has a first speaker 13 disposed therein;

[0026] The top shell 2 is connected to the bottom shell 1 and is provided with a first sound outlet 401 corresponding to the first speaker 13;

[0027] The first speaker 13 is fixedly connected to the surface shell 2, and a suppression mechanism 6 is provided between the first speaker 13 and the bottom shell 1. The suppression mechanism 6 includes a shock-absorbing frame 61 with two ends respectively pressing on the top of the inner cavity of the bottom shell 1 and the top of the first speaker 13.

[0028] This utility model provides a ceiling speaker that suppresses cabinet resonance. The first speaker has a high structural strength. A support frame serves as a support, allowing the first speaker to be integrally connected to the bottom and top shells, significantly improving the structural strength. This increased structural strength not only prevents resonance and improves sound quality, but also allows the bottom shell to be made of a thinner material, reducing weight and cost.

[0029] Furthermore, as a preferred embodiment of this solution, but not limiting, the shock-absorbing frame 61 includes an upper top plate 611 for pressing against the bottom housing 1, a lower top plate 612 for pressing against the first speaker 13, and a shock-absorbing portion 613 connecting the upper top plate 611 and the lower top plate 612. The upper and lower top plates help increase the contact area and provide better support. The shock-absorbing portion can undergo moderate elastic deformation to achieve a shock-absorbing and buffering effect.

[0030] Furthermore, as a preferred embodiment of this solution but not limiting, the two ends of the shock absorbing portion 613 are respectively connected to the same side of the upper top plate 611 and the lower top plate 612, so that the support frame is C-shaped as a whole, which is conducive to bending under stress.

[0031] Furthermore, as a preferred embodiment of this solution but not limiting, the suppression mechanism 6 further includes a shock-absorbing member 62 disposed between the lower top plate 612 and the first speaker 13. This avoids rigid contact with the first speaker, thereby protecting the first speaker from damage and providing shock absorption.

[0032] Furthermore, as a preferred embodiment of this solution but not limiting, the shock absorber 62 is made of silicone or rubber, or can be made of materials with a buffering effect such as sponge or spring.

[0033] Furthermore, as a preferred embodiment of the present solution but not a limitation, the upper plate 611 is provided with a through hole 614 and a connecting member 615 provided on the through hole 614 and connected to the bottom shell 1 .

[0034] Furthermore, as a preferred embodiment of this solution but not limiting, the top surface of the bottom shell 1 is concavely provided with a reinforcing rib 63, and the connecting member 615 is riveted to the reinforcing rib 63. Providing the reinforcing rib is beneficial for reducing the thickness of the bottom shell while maintaining strength.

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the reinforcing rib 63 includes two straight ribs 631 extending diagonally along the bottom shell 1 and crossing each other in a cross shape, and an arc rib 632 connecting the ends of two adjacent straight ribs 631 and convexly bending toward the intersection.

[0036] Furthermore, as a preferred embodiment of this solution but not limiting, the first speaker 13 includes a magnetic guide post 57, a guide post hole 571 is provided in the middle of the magnetic guide post 57, and the lower top plate 612 is pressed against the magnetic guide post 57 and is arranged away from the guide post hole 571 to avoid affecting the sound of the first speaker.

[0037] Furthermore, as a preferred embodiment of this solution but not a limitation, the connection between the shock absorbing portion 613 and the upper top plate 611 and the lower top plate 612 is suspended relative to the bottom shell 1 and the magnetic guide column 57. This is conducive to elastic deformation of the shock absorbing portion under stress, thereby reducing vibration.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
