Description

Technical Field

[0001] This utility model belongs to the field of audio equipment technology, specifically relating to a metal frame type low resonance speaker enclosure. Background Technology

[0002] In speaker design, the cabinet structure has a significant impact on sound quality. Traditional speakers often use a single wooden or plastic cabinet, which, while offering some sound insulation, is prone to distortion in the low-frequency response due to cabinet resonance. To improve low-frequency clarity and dynamic range, the industry has gradually developed metal frame structures. These high-rigidity metal frames enhance cabinet stability, effectively suppressing vibration interference and achieving lower resonance frequencies and higher sound fidelity. This technology has become one of the important directions in high-performance speaker design.

[0003] In the audio industry, speaker cabinet design is crucial to sound reproduction quality. Traditional speaker cabinets are divided into two types: wooden and all-metal, but both have obvious limitations: wooden cabinets are prone to resonance, have unstable structures, and the fixing method leads to sound pollution and poor high-frequency performance; all-metal cabinets face problems such as internal reflection interference, inherent resonance, heavy weight, and high cost. Utility Model Content

[0004] The purpose of this invention is to provide a metal frame type low resonance speaker enclosure, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A metal-framed low-resonance speaker enclosure, including

[0007] The enclosure includes a front aluminum alloy panel on one side of the enclosure, a rear aluminum alloy panel on the other side of the enclosure, multiple metal connecting rods along the depth of the enclosure, the metal connecting rods passing through and connecting the front and rear aluminum alloy panels to form an integrated load-bearing frame, a speaker unit installed in the inner cavity of the enclosure, a wooden enclosure shell fixed to the metal frame by a floating installation method, and aluminum alloy legs rigidly connected to the metal frame for dissipating vibration energy.

[0008] In a preferred embodiment of this utility model, the speaker unit is fixed to the front aluminum alloy panel by a custom metal flange, and a high-damping vibration isolation washer is provided between the flange and the panel. The high-damping vibration isolation washer is sandwiched between the flange and the front aluminum alloy panel.

[0009] As a preferred embodiment of this utility model, the high-damping vibration isolation washer is made of a high-elasticity material, and the flange is fastened to the front aluminum alloy panel by screws.

[0010] In a preferred embodiment of this utility model, the number of metal connecting rods is four to eight, and the metal connecting rods are respectively arranged at the four corners and the middle area of ​​the box.

[0011] As a preferred embodiment of this utility model, the metal connecting rod is made of steel, titanium or aluminum alloy, and each end of the metal connecting rod is connected to the front aluminum alloy panel and the rear aluminum alloy panel respectively by threaded fasteners, the fasteners being made of stainless steel.

[0012] As a preferred embodiment of this utility model, the wooden box shell is covered by a metal frame and is made of multiple wooden boards spliced ​​together. The surface of the wooden shell is coated with a waterproof coating to prevent it from getting damp and deforming.

[0013] As a preferred embodiment of this utility model, the aluminum alloy leg is a forged one-piece structure, which is connected to the rear aluminum alloy panel by bolts and extends to the ground. The bottom of the leg is provided with a rubber pad to prevent slippage and absorb vibration transmitted from the ground.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: by suspending and isolating the speaker unit with the metal frame, the cabinet resonance is significantly suppressed and the sound coloration and distortion are reduced.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a metal frame type low-resonance speaker enclosure, comprising,

[0026] The enclosure 100 includes a front aluminum alloy panel 101 on one side of the enclosure 100, a rear aluminum alloy panel 102 on the other side of the enclosure 100, multiple metal connecting rods 103 arranged along the depth direction of the enclosure 100, the metal connecting rods 103 passing through and connecting the front and rear aluminum alloy panels to form an integrated load-bearing frame, a speaker unit 104 disposed in the inner cavity of the enclosure 100, a wooden enclosure shell 105 fixed to the metal frame by a floating installation method, and an aluminum alloy stand 106 rigidly connected to the metal frame for dissipating vibration energy.

[0027] The number of metal connecting rods 103 can be adjusted to 4, 6, 8 or even more depending on the size of the box 100. The wooden box shell 105 can be replaced with non-load-bearing decorative materials such as high-density fiberboard or composite materials such as carbon fiber. The legs can be made of metal cone feet, vibration-damping rubber bases or magnetic levitation feet.

[0028] Specifically, the speaker unit 104 is fixed to the front aluminum alloy panel 101 by a custom metal flange. A high-damping vibration isolation washer 107 is provided between the flange and the panel, and the high-damping vibration isolation washer 107 is sandwiched between the flange and the front aluminum alloy panel 101.

[0029] Furthermore, the high-damping vibration isolation washer 107 is made of a highly elastic material, and the flange is fastened to the front aluminum alloy panel 101 by screws.

[0030] Furthermore, there are four to eight metal connecting rods 103, which are respectively arranged at the four corners and the middle area of ​​the box 100.

[0031] Furthermore, the metal connecting rods 103 are made of steel, titanium, or aluminum alloy. Each metal connecting rod 103 is connected at both ends to the front aluminum alloy panel 101 and the rear aluminum alloy panel 102 respectively via threaded fasteners made of stainless steel.

[0032] Preferably, the wooden outer shell 105 is wrapped around the metal frame and is made of multiple wooden boards. The surface of the wooden outer shell is coated with a waterproof coating to prevent it from warping due to moisture.

[0033] It should be noted that the aluminum alloy leg 106 is a forged one-piece structure, which is connected to the rear aluminum alloy panel 102 by bolts and extends to the ground. The bottom of the leg is equipped with a rubber pad to prevent slippage and absorb vibration transmitted from the ground.

[0034] When in use, the speaker unit 104 is powered on and produces sound. The vibrations generated are effectively isolated by the high-damping vibration isolation washer 107. Most of the energy is conducted only between the metal frame, which consists of the front aluminum alloy panel 101, the rear aluminum alloy panel 102 and multiple metal connecting rods 103 and the aluminum alloy stand 106, and is not transmitted to the wooden cabinet shell 105. This significantly suppresses the distortion caused by the resonance of the cabinet 100. Excess mechanical energy is quickly dissipated or grounded through the metal frame and stand, ensuring that the speaker can maintain a clear, distortion-free, and high-purity acoustic performance. For example, in one specific embodiment, the front aluminum alloy panel 101 and the rear aluminum alloy panel 102 are high-strength precision-machined aluminum alloy plates. They are connected to the rear end by 6 to 8 high-strength steel or aluminum metal connecting rods 103, which are locked in place by countersunk holes to form a sturdy main frame of the cabinet. The speaker unit 104 is mounted on the front aluminum alloy panel 101 with a custom metal flange and is equipped with a high-damping vibration isolation washer 107 to minimize the vibration coupling between the unit and the metal frame. The wooden cabinet shell 105 only serves as a covering and does not participate in load-bearing or transmit unit vibration. The aluminum alloy stand 106 adopts an integral forged structure and is rigidly connected to the metal rear frame at the bottom, effectively transferring the mechanical energy inside the speaker cabinet to the ground through the stand, further reducing cabinet resonance. As a result, the speaker can provide excellent acoustic performance and structural stability even in high dynamic music playback scenarios during actual use. Ordinary users can use it by standard wiring without special operation requirements.

[0035] In summary, the floating isolation connection between the speaker unit 104 and the metal frame significantly suppresses the resonance of the cabinet 100 and reduces sound coloration and distortion. The integrated metal frame, with its front and rear aluminum plates and multiple metal connecting rods 103, enhances structural stability and prevents deformation and loosening during high-dynamic-range playback. The overall design of the aluminum alloy frame and aluminum alloy stands 106 effectively dissipates mechanical energy and further reduces resonance. These improvements enhance the sound purity and dynamic range of the speaker, while combining the high strength of metal with the damping characteristics of the wooden cabinet shell 105, thus solving many problems of the traditional cabinet 100.
