Description

Technical Field

[0001] The present invention relates to the technical field of speaker boxes, and in particular to a shock-resistant aluminum speaker box. Background Art

[0002] In the design and manufacturing of audio equipment, speakers, as core components of sound output, are crucially affected by the material of their enclosures. Traditional speaker designs often utilize a single material, such as wood or plastic, for their enclosures. Each of these materials has its own advantages and disadvantages. Wooden speakers are widely recognized for their excellent acoustic properties, providing a warm, natural sound performance; however, their limited physical strength makes them susceptible to damage during handling and use. With technological advancements, aluminum alloys are increasingly being used in speaker enclosures due to their high strength, lightweight construction, and excellent protective properties. This aluminum enclosure not only improves the durability of the speaker but also enhances its resistance to external environmental factors.

[0003] Although the aluminum alloy shell can enhance the physical protection and service life of the speaker, relying solely on aluminum materials also has certain limitations. First, the resonance characteristics of the metal material itself may cause additional noise interference, affecting the purity of the sound quality; secondly, aluminum speakers usually lack sufficient internal sound absorption measures, which are prone to standing waves, resulting in an uneven frequency response curve and reducing the layering and fullness of the sound; in addition, the ability to resist external vibrations is insufficient. Once subjected to external impact, the vibration will be directly transmitted to the sound unit, further affecting the sound quality performance. Therefore, we have a shock-resistant aluminum speaker that combines the outer aluminum shell and the wooden shell to achieve complementarity between the material properties, thereby ensuring the physical protection of the speaker while taking into account the improvement of sound quality.

[0030] Example 1: A shock-resistant aluminum speaker, referring to Figure 1-Figure 5As shown, it includes a support base 1 and a main speaker 2. The support base 1 is the load-bearing carrier of the speaker. The main speaker 2 is fixedly assembled on the support base 1. The back of the main speaker 2 is fixedly connected to a guide frame 7, which extends upward from the back of the main speaker 2. A handle 8 for carrying the speaker is fixedly installed on the top of the guide frame 7; the main speaker 2 body is composed of an outer first aluminum box 21 and an inner first wooden box 23. The first aluminum box 21 is fixedly installed on the top surface of the support base 1. Buffer frames 22 are provided at the four top corners of the inner wall of the first aluminum box 21. The first wooden box 23 is supported between the four buffer frames 22 in the first aluminum box 21. A partition is provided between the first aluminum box 21 and the first wooden box 23. A plurality of heat conducting plates 5 are staggered in the partition between the first aluminum box 21 and the first wooden box 23. The partition between the first aluminum box 21 and the first wooden box 23 is also filled There is honeycomb sound-absorbing cotton 6, which is attached and spread between the buffer frame 22 and the heat conduction plate 5. The honeycomb sound-absorbing cotton 6 is used to reduce standing waves and resonance in the box. The front side of the first wooden box 23 is fixedly connected to a wooden board 24, and the wooden board 24 is equipped with a first speaker 25 through a through-hole in the middle. A first bass reflex tube 26 is provided on the inner side of the wooden board 24 of the first wooden box 23. The first bass reflex tube 26 is used to improve the sound quality of the speaker. The first aluminum box 21 is used as the outer shell of the speaker. While ensuring the basic rigidity and strength of the speaker, the first wooden box 23 is used as the assembly carrier of the first speaker 25 to improve the acoustic performance of the speaker. The buffer frame 22 is used to provide elastic support between the first aluminum box 21 and the first wooden box 23, and the honeycomb sound-absorbing cotton 6 is used to further optimize the acoustic performance of the speaker and provide a buffering effect, so that the speaker can take into account good seismic resistance and acoustic performance.

[0031] Reference Figure 3 and Figure 4 As shown, a support pad 3 is symmetrically fixed to one side of the bottom of the support seat 1 near the first speaker 25, and the bottom surface of the support pad 3 is a rubber pad with a rough texture. A guide rod 31 is fixedly connected to the bottom surface of the support seat 1, and the guide rod 31 is located inside the support pad 3. A buffer spring 32 is provided on the outer sleeve of the guide rod 31, and the buffer spring 32 is located between the support seat 1 and the support pad 3. The buffer spring 32 is used for spring support on the rubber pad on the bottom surface of the support pad 3. A sliding wheel 4 is symmetrically fixed to the side of the bottom of the support seat 1 facing away from the first speaker 25, and the sliding wheel 4 has a built-in brake. The sliding wheel 4 is flush with the support pad 3 in its natural state, and the support pad 3 cooperates with the buffer spring 32 inside it to provide shock-absorbing support to the support seat 1, and cooperates with the sliding wheel 4 to facilitate users to push the speaker for use.

[0032] Reference Figure 4 and Figure 5As shown, the buffer frame 22 is composed of a first elastic frame 221 and a first spring 222. Four first elastic frames 221 are provided and are fixedly arranged at the left and right edges of the upper and lower inner walls of the first aluminum box 21. The four first elastic frames 221 are respectively supported at the corresponding edges outside the first wooden box 23. The frame of the first elastic frame 221 in contact with the first wooden box 23 has toughness. The first springs 222 are evenly arranged inside the first elastic frame 221. The first springs 222 are used to elastically support each top corner of the first wooden box 23. The first springs 222 provide elastic buffering between the first aluminum box 21 and the first wooden box 23 to reduce vibration transmitted from the first aluminum box 21 to the first wooden box 23 and the internal sound unit, thereby enhancing the seismic performance of the main speaker 2.

[0033] Reference Figure 6 As shown, a damping rod 27 is provided between the wooden board 24 and the first speaker 25. There are multiple damping rods 27 and they are circumferentially distributed around the periphery of the first speaker 25. One end of the damping rod 27 is hinged to the wooden board 24, and the other end of the damping rod 27 is hinged to the shell of the first speaker 25. A guide plate 28 is symmetrically and obliquely provided inside the first wooden box 23. The guide plate 28 is used to guide and disperse the sound waves emitted backward by the first speaker 25 unit to avoid direct reflection back to the diaphragm, thereby improving the purity of the sound.

[0034] Reference Figure 5 and Figure 7 As shown, a ventilation plate 211 is provided on the back of the first aluminum box 21. The ventilation plate 211 is located at the intersection of the back of the first aluminum box 21 and the corresponding heat conducting plate 5. The ventilation plate 211 is densely provided with honeycomb-shaped air holes. The outer wall of the ventilation plate 211 is inclined from low to high toward the inner side of the box body, and the box plate of the first aluminum box 21 is blocked in the upper half of the outer side of the ventilation plate 211. The inclined ventilation plate 211 can ensure good heat dissipation of the main speaker 2 while reducing the risk of rainwater falling from the ventilation plate 211 into the first aluminum box 21 on rainy days, thereby increasing the service life of the speaker.

[0035] When the user needs to move the position of the speaker, the handle 8 can be used to conveniently push the entire speaker. When moving on the ground, the handle 8 is operated to lift one side of the support base 1 so that the sliding wheel 4 at the bottom of the support base 1 can touch the ground alone, and the speaker can be easily pushed. When placing the speaker for use, the support pad 3 at the bottom of the support base 1 contacts the ground under the elastic support of the buffer spring 32, and the sliding wheel 4 is locked with the brake to provide stable support. At this time, the buffer frame 22 elastically supports each top corner of the first wooden box 23 through the internal first spring 222, thereby effectively isolating the vibration transmitted from the first aluminum box 21 to the first wooden box 23. When the first speaker 25 is working, the wooden board 24 on the first wooden box 23 helps to absorb and diffuse sound waves, thereby reducing unnecessary resonance and resonance when the first speaker 25 is working, thereby avoiding the negative impact of these factors on the sound and improving the good acoustic performance of the main speaker 2. When the vibration of the first speaker 25 is transmitted to the inside of the main body of the first wooden box 23, the first bass reflex The tube 26 can regulate the airflow in the box, thereby enhancing the low-frequency response. At the same time, the sound waves emitted backward by the first speaker 25 can be guided and dispersed by the guide plate 28 set inside the first wooden box 23, avoiding direct reflection back to the diaphragm, thereby improving the sound purity of the main speaker 2. The heat generated by the first speaker 25 when working will be transferred through the first wooden box 23 to the heat conducting plate 5 staggered with it, and the heat conducting plate 5 will transfer the heat to the outer shell of the first aluminum box 21. The ventilation plate 211 on the back of the first aluminum box 21 can promote air circulation and heat dissipation. At the same time, the inclined design of the ventilation plate 211 can reduce the risk of rainwater intrusion. Since the honeycomb sound-absorbing cotton 6 is filled in the compartment between the first aluminum box 21 and the first wooden box 23, it fits tightly with the buffer frame 22 and the heat conducting plate 5. The honeycomb sound-absorbing cotton 6 can effectively absorb standing waves and stray reflections in the box, reduce resonance, and further optimize the acoustic performance. It is circumferentially hinged between the wooden board 24 and the shell of the first speaker 25 with the damping rod 27 to absorb vibration energy and reduce the transmission of vibration of the first speaker 25.

Two sets of auxiliary speakers 11 are symmetrically slidably assembled between the guide rail 10 and the guide plate 9 of the main speaker 2. The auxiliary speakers 11 can be flexibly unfolded and stored on the top of the main speaker 2, so that this speaker can provide a richer and more three-dimensional sound experience.

[0037] Reference Figure 1 、 Figure 8 and Figure 9As shown, the secondary speaker 11 includes an outer second aluminum box 111 and an inner second wooden box 115. The second aluminum box 111 is slidably installed between the guide plate 9 and the guide rail 10 of the main speaker 2 through a mounting plate 112. The top and bottom of the second aluminum box 111 are fixedly equipped with second elastic frames 113, and a plurality of second springs 114 are provided inside the second elastic frames 113. The second aluminum box 111 elastically supports the two inner second wooden boxes 115 through the second elastic frames 113. The two second wooden boxes 115 fit tightly together. The compartment between the second aluminum box 111 and the second wooden box 115 is also filled with honeycomb sound-absorbing cotton 6. Second speakers 116 are installed on the front sides of the second wooden boxes 115. The two second speakers 116 are responsible for playing high-frequency or medium-frequency sounds respectively. The two second wooden boxes 115 are respectively equipped with second bass reflex tubes 117. A second ventilation plate 118 is provided on the back of the second aluminum box 111.

[0038] Reference Figure 1 and Figure 9 As shown, the front sides of the first speaker 25 of the main speaker 2 and the second speaker 116 of the auxiliary speaker 11 are covered with a mesh cover 12, which is used to protect the diaphragms of the first speaker 25 and the second speaker 116 from external damage.

[0039] Reference Figure 2 and Figure 10 As shown, a slide groove is provided on the side of the guide frame 7 facing away from the main speaker 2, and thread grooves 71 are evenly spaced in the slide groove near the upper middle part of the guide frame 7. A hook block 13 is slidably assembled on the slide groove of the guide frame 7, and the hook block 13 is rotatably connected to a fastening bolt 14 that adapts to the thread groove 71. The hook block 13 is used to suspend the entire speaker. The hook block 13 is tightened to the thread grooves 71 at different heights of the guide frame 7 by the fastening bolts 14, so that the speaker can be hung on hooks at different heights of the wall for placement.

[0040] When the speaker needs to be hung, slide the hook block 13 in the slide groove on the side of the guide frame 7 away from the main speaker 2 to the required height, then turn the fastening bolt 14 to screw it into the threaded groove 71 of the guide frame 7 and lock it, and the entire speaker can be hung on the hook on the wall for placement. When the sound field of the speaker needs to be expanded, slide and unfold the two sets of auxiliary speakers 11 between the guide rail 10 and the guide plate 9 on the top of the main speaker 2, so that the auxiliary speakers 11 can cooperate with the main speaker 2 to provide stereo sound. Due to the second aluminum box 11 in the auxiliary speaker 11 1 and the second wooden box 115 are also filled with honeycomb sound-absorbing cotton 6, and are provided with a second bass reflex tube 117 and a second ventilation plate 118, so that the auxiliary speaker 11 can also maintain good sound quality and heat dissipation performance, and use two second speakers 116 to play high-frequency or medium-frequency sounds respectively, and cooperate with the first speaker 25 of the main speaker 2, thereby providing a richer and more three-dimensional sound experience. During use, the mesh cover 12 always protects the diaphragms of the first speaker 25 and the second speaker 116, and can also improve the service life of the entire speaker.
