Description

Technical Field

[0001] This utility model relates to the field of loudspeaker assembly technology, and more specifically, to a loudspeaker frame. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. It mainly consists of a frame, surround, diaphragm, voice coil, and magnetic circuit system. The frame is the "skeleton" of the loudspeaker, and other parts or components need to be installed or fixed on the frame.

[0003] As people's living standards improve, their pursuit of quality of life also increases, leading to more stringent requirements for speaker sound quality. However, the speaker basket itself is not an absolutely rigid body. At certain frequencies, the basket will resonate with the voice coil and diaphragm, generating noise and affecting sound quality.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a speaker basket frame in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: a speaker basket, including a top support and a bottom support, the top support and the bottom support being coaxially arranged, a first connecting part and a second connecting part being fixedly connected between the top support and the bottom support, the first connecting part and the second connecting part each including a plurality of connecting blocks distributed at equal intervals, the number of connecting blocks in the second connecting part being greater than the number of connecting blocks in the first connecting part, a groove being provided on the top support, and a damping ring being engaged in the groove.

[0007] The present invention is further configured such that: a limiting groove is provided on the side wall of the settling tank, and an annular protrusion is fixedly connected to the damping ring, the annular protrusion being engaged with the limiting groove.

[0008] The present invention is further configured such that: the damping ring includes a connecting ring and an abutting surface fixedly connected to the connecting ring, the abutting surface is located on the side of the connecting ring away from the annular protrusion and is perpendicular to the connecting ring, and the connecting ring is provided with a plurality of protrusions distributed at equal intervals.

[0009] The present invention is further configured such that: the second connecting part includes three connecting blocks, the included angle between adjacent connecting blocks of the second connecting part is 60 degrees, and the first connecting part includes two connecting blocks, the included angle between adjacent connecting blocks of the first connecting part is 90 degrees.

[0010] The present invention is further configured such that: a filling cavity is provided inside the connecting block, an injection port communicating with the filling cavity is provided on the connecting block, and the filling cavity is filled with damping material.

[0011] The present invention is further configured such that each of the connecting blocks is fixedly connected with a heat sink.

[0012] The present invention is further configured such that: the top support and the bottom support are respectively provided with a first mounting hole and a second mounting hole.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By setting a first connecting part and a second connecting part, and the number of connecting blocks in the first connecting part and the second connecting part are different, the connecting blocks are set asymmetrically. The asymmetrical setting leads to different densities between the connecting blocks, which can effectively disperse the resonance energy and decompose the single, strong resonance peak into multiple weak and dispersed resonance points, thereby reducing the resonance between the iron frame, voice coil, and diaphragm.

[0015] By filling the connecting blocks with damping material, the damping material can dissipate mechanical vibration energy in the form of heat energy, thereby effectively mitigating the resonance effect. Combined with the asymmetrically distributed connecting blocks, the resonance frequency of the iron frame can be greatly reduced, thereby reducing noise generation and making the speaker have better sound effects.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In one possible embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, a loudspeaker frame includes a top support 1 and a bottom support 2. The top support 1 and the bottom support 2 are respectively provided with a first mounting hole 101 and a second mounting hole 201 for fixing to the surround, diaphragm, and voice coil. The top support 1 and the bottom support 2 are coaxially arranged. A symmetrically distributed first connecting part 3 and a second connecting part 4 are fixedly connected between the top support 1 and the bottom support 2. The first connecting part 3 and the second connecting part 4 serve as connecting supports. Each of the first connecting part 3 and the second connecting part 4 includes multiple equally spaced connecting blocks 5. The number of connecting blocks 5 in the first connecting part 3 is greater than the number of connecting blocks 5 in the second connecting part 4. The second connecting part 4 includes three connecting blocks 5, and the included angle between adjacent connecting blocks 5 in the second connecting part 4 is 60 degrees. The first connecting part 3 includes two connecting blocks 5, and the included angle between adjacent connecting blocks 5 in the first connecting part 3 is 90 degrees. This results in the asymmetrical arrangement of connecting blocks 5 between the top support 1 and the bottom support 2. The asymmetrical arrangement leads to different densities between the connecting blocks 5, which can effectively disperse the resonance energy and decompose the single, strong resonance peak into multiple weak and dispersed resonance points, thereby reducing the resonance between the iron frame, voice coil, and diaphragm.

[0023] For further details, please refer to Figure 1 , Figure 2 and Figure 4 As shown, a filling cavity 502 is provided inside the connecting block 5, and an injection port 501 connected to the filling cavity 502 is provided on the connecting block 5. The filling cavity 502 is filled with damping material, and the damping material is filled and poured through the injection port 501. When the connecting block 5 resonates, the damping material can convert mechanical vibration energy into heat energy and dissipate it, thereby effectively mitigating the resonance effect. With the asymmetrical distribution of the connecting blocks 5, the resonance frequency of the iron frame can be greatly reduced, thereby reducing noise generation and making the speaker have better sound effects. Each connecting block 5 is fixedly connected with a heat sink 10, which can increase the contact area with the air and dissipate the heat energy converted by the damping material in time.

[0024] For further details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a groove 6 is provided on the top support 1, and a damping ring 7 is engaged in the groove 6. By setting the damping ring 7, the damping ring 7 can directly abut against the voice coil and diaphragm. The damping ring is made of rubber material, which can effectively absorb mechanical kinetic energy and reduce the occurrence and amplitude of resonance. A limiting groove 8 is provided on the side wall of the groove 6. An annular protrusion 9 is fixedly connected to the damping ring 7. The annular protrusion 9 is engaged with the limiting groove 8, thereby realizing the limiting of the damping ring 7 by the top support 1. The damping ring 7 includes a connecting ring 701 and an abutting surface fixedly connected to the connecting ring 701. The abutting surface is located on the side of the connecting ring 701 away from the annular protrusion 9 and is perpendicular to the connecting ring 701. The connecting ring 701 is provided with multiple equally spaced protrusions 702. By setting the protrusions 702, multiple staggered peaks and valleys can be formed, thereby effectively decomposing the resonance frequency, reducing the resonance frequency, and reducing noise.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
