It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0034] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0035] See also Figure 1-Figure 5 An embodiment of the utility model provides a speaker bracket, including a first speaker 10 and a second speaker 20, wherein the second speaker 20 is arranged in front of the first speaker 10, and the second speaker 20 is coaxially arranged with the first speaker 10 and has the same sound output direction. The utility model adopts a coaxial structural design of the first speaker 10 and the second speaker 20, which can not only save the design space inside the speaker box, but also improve the sound effect.

[0036] In this embodiment, the first speaker 10 is a woofer, and the second speaker 20 is a tweeter. Of course, in other embodiments of the present invention, the first speaker 10 is a tweeter, and the second speaker 20 is a woofer. The first speaker 10 and the second speaker 20 of this embodiment can be replaced and installed, so as to achieve different coaxial sound effects.

[0037] In this embodiment, the diameter ratio of the first speaker 10 to the second speaker 20 is in the range of 0.15-0.6. Specifically, the diameter of the second speaker 20 in this embodiment determines the frequency when the frequency response curve of the first speaker 10 is truncated. The smaller the diameter of the second speaker 20, the smaller the truncation frequency of the first speaker 10. In this embodiment, the diameter of the second speaker 20 is 23mm, and the diameter of the first speaker 10 is 65mm; the current diameter ratio of the second speaker 20 to the first speaker 10 is 0.35, and the ratio range is 0.15-0.65.

[0038] In this embodiment, the first speaker 10 includes a first speaker basin frame 11, a first speaker 10 folding ring 12 is arranged in the first speaker basin frame 11, a first speaker diaphragm 13 is arranged at the center of the first speaker folding ring 12, and a dust cap 14 is arranged on the first speaker diaphragm 13. It should be noted that the specific structure and working principle of the first speaker basin frame 11, the first speaker folding ring 12, the first speaker diaphragm 13 and the dust cap 14 of this embodiment belong to the prior art, which is not the focus of this embodiment, and will not be described in detail.

[0039] In this embodiment, a speaker bracket 30 is also included. The speaker bracket 30 is installed on the first speaker basin frame 11 and is used to support the second speaker 20. The speaker bracket 30 is provided with a first reflection arc surface 31. The first reflection arc surface 31 is provided on the first speaker folding ring 12 and away from the dust cap 14. The sound waves of the first speaker 10 are gathered and converged forward through the first reflection arc surface 31 and continue to emit sound forward. By providing the speaker bracket 30, the speaker bracket 30 can combine the first speaker 10 and the second speaker 20 into one body; and the speaker bracket 30 has the first reflection arc surface 31. The first reflection arc surface 31 is provided on the first speaker folding ring 12 and away from the dust cap 14. The first reflection arc surface 31 reflects the sound waves of the first speaker 10 diffused horizontally through the first reflection arc surface 31, so that the sound waves are gathered and converged forward and continue to emit sound forward, thereby increasing the loudness of the speaker box.

[0040] The speaker bracket provided by the embodiment of the utility model can combine the first speaker 10 and the second speaker 20 into one through the speaker bracket 30, and the coaxial structure design of the first speaker 10 and the second speaker 20 can not only save the design space inside the speaker box, but also make the sound effect better; and the speaker bracket 30 is provided with the first reflection arc surface 31, the first reflection arc surface 31 is arranged on the first speaker folding ring 12 and away from the side of the dust cap 14, the first reflection arc surface 31 reflects the sound waves horizontally diffused by the first speaker 10 through the first reflection arc surface 31, so that the sound waves are gathered and converged forward and continue to emit sound forward, thereby increasing the loudness of the speaker box.

[0041] In this embodiment, the first reflective arc surface 31 is a continuous arc surface, and the first reflective arc surface 31 is disposed around the outside of the first speaker folding ring 12. Since the first reflective arc surface 31 is a continuous arc surface and is disposed around the outside of the first speaker folding ring 12, the sound waves emitted by the first speaker folding ring 12 as a whole can be gathered forward and continue to emit sound forward, thereby increasing the loudness of the speaker box.

[0042] In this embodiment, the distance between the first reflection arc surface 31 and the first speaker fold ring 12 is 1-3.5 mm. Specifically, the minimum distance between the first reflection arc surface 31 and the first speaker fold ring 12 is 2.1 mm, so as to effectively avoid the first speaker fold ring 12 being too close to the first reflection arc surface 31, which may cause the first speaker fold ring 12 to hit the first reflection arc surface 31, or the distance between the first speaker fold ring 12 and the first reflection arc surface 31 being too large, which may cause the convergence effect to be unclear.

[0043] In this embodiment, the distance between the first speaker diaphragm 13 and the bottom of the second speaker 20 is 5-10mm. Specifically, in this embodiment, the distance between the first speaker diaphragm 13 and the bottom of the second speaker 20 is preferably 7mm. The power of the first speaker 10 when in use is 12w. When the power of the first speaker 10 is greater, the distance between the first speaker 10 and the second speaker 20 is greater, so that the first speaker diaphragm 13 can be effectively prevented from hitting the second speaker 20 to generate noise, thereby effectively improving the experience during use.

[0044] In this embodiment, the upper end wall of the first speaker basin frame 11 is bent to form a folding groove 110, and mounting holes 111 for screws to penetrate are provided on the groove wall of the folding groove 110 and the speaker bracket 30. The screws are vertically driven into the mounting holes 111, thereby effectively fixing the speaker bracket 30 on the first speaker basin frame 11, and preventing the speaker bracket 30 from falling off the first speaker basin frame 11.

[0045] In this embodiment, the speaker bracket 30 is provided with a plurality of support arms 32, and a mounting ring 33 is provided in the middle of the plurality of support arms 32, and the second speaker 20 is mounted in the mounting ring 33. Specifically, the support arms 32 of this embodiment can be integrally formed with the support arms 32, so that the installation process of the support arms 32 on the speaker bracket 30 is reduced, thereby improving production efficiency.

[0046] Of course, in another embodiment of the present invention, the support arm 32 can also be fixedly connected to the speaker bracket 30, for example, by welding, riveting, etc. In this way, not only the connection strength between the support arm 32 and the speaker bracket 30 is ensured, but also the support arm 32 and the speaker bracket 30 can be transported separately during transportation and assembled when arriving at the assembly factory, thereby reducing transportation space and saving transportation costs.

[0047] In addition, in other embodiments of the present invention, the support arm 32 can also be detachably connected to the speaker bracket 30, such as by threaded connection, pin connection, hook connection, etc. In this way, the space occupied by the support arm 32 and the speaker bracket 30 during transportation can be reduced, saving transportation costs. And when the support arm 32 is damaged, it can be disassembled and replaced, reducing maintenance costs.

[0048] In this embodiment, the mounting ring 33 is provided with a second reflection arc surface 330, and the sound waves of the second speaker 20 are gathered and converged forward through the second reflection arc surface 330 and continue to emit sound forward. The second reflection arc surface 33 is arranged opposite to the folded ring of the second speaker 20, and the second reflection arc surface 330 reflects the sound waves horizontally diffused by the second speaker 10 through the second reflection arc surface 330, so that the sound waves are gathered and converged forward and continue to emit sound forward, thereby increasing the loudness of the speaker.

[0049] And the slope of the second reflection arc surface 330 is smaller than the slope of the first reflection arc surface 31. When the slope is larger, the convergence effect is more obvious. The slope of the second reflection arc surface 330 is smaller than the slope of the first reflection arc surface 31. At this time, the width of the sound wave beam emitted by the second speaker 20 is naturally smaller than the width of the sound wave beam emitted by the first speaker 10. At this time, the sound waves emitted by the second speaker 20 are reflected by the second reflection arc surface 330, so that the sound waves converge forward and continue to emit sound forward, thereby increasing the loudness of the speaker.

[0050] The slope of the second reflection arc surface 330 of this embodiment refers to the coincidence of the projection of the arc vertex toward the horizontal plane and the projection of the arc bottom toward the vertical plane, the distance from the coincidence point to the arc vertex is H1, the distance from the coincidence point to the arc bottom is H2, and the slope of the second reflection arc surface 330 is H1 / H2, which describes the inclination degree of the reflection surface; the slope of the first reflection arc surface 31 refers to the coincidence of the projection of the arc vertex toward the horizontal plane and the projection of the arc bottom toward the vertical plane, the distance from the coincidence point to the arc vertex is H3, the distance from the coincidence point to the arc bottom is H4, and the slope of the first reflection arc surface 31 is H3 / H4, which describes the inclination degree of the reflection surface.

[0051] In this embodiment, the speaker bracket 30 is provided with a first notch 34 and a second notch 331 provided on one side of the mounting ring 33, and the wire sequentially passes through the first notch 34 and the second notch 331 to connect the second speaker 20 to a power source. Specifically, in this embodiment, the first notch 34 is provided on the first speaker bracket 10, the second notch 331 is provided on the mounting ring 33, the wire sequentially passes through the second notch 331 and the first notch 34 to connect the second speaker 20 to a power source, and the wire is bundled in the support arm 32 to prevent the wire from interfering with the first speaker diaphragm 13.

[0052] In summary, the speaker bracket provided by the embodiment of the utility model can combine the first speaker 10 and the second speaker 20 into one through the speaker bracket 30, and the coaxial structure design of the first speaker 10 and the second speaker 20 can not only save the design space inside the speaker box, but also make the sound effect better; and there is the first reflection arc surface 31 on the speaker bracket 30, the first reflection arc surface 31 is arranged on the first speaker folding ring 12 and away from the side of the dust cap 14, the first reflection arc surface 31 reflects the sound waves horizontally diffused by the first speaker 10 through the first reflection arc surface 31, so that the sound waves are gathered and focused forward and continue to emit sound forward, thereby increasing the loudness of the speaker box.
