[0025] The speaker of this specification is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.
[0026] See also Figure 1As shown, an embodiment of the present specification provides a sound box, including: a sound cavity body 10 and a sound module 20. The sound cavity body 10 has a first sound cavity 11 inside, and the side wall of the sound cavity body 10 is provided with a first sound outlet 12 and a second sound outlet 13, and the first sound outlet 12 and the second sound outlet 13 are both connected to the first sound cavity 11. Part of the side wall of the sound cavity body 10 extends outward and bends to form a reflex tube 14, one end of the reflex tube 14 is connected to the first sound cavity 11, and the other end of the reflex tube 14 passes through the side wall of the sound cavity body 10 and extends into the first sound cavity 11, and is connected to the first sound outlet 12. The sound module 20 is installed at the second sound outlet 13. Optionally, the reflex tube 14 and the sound cavity body 10 can be integrally formed for easy processing. Or it can be arranged in sections, and the reflex tube 14 is assembled to the sound cavity body 10, which can also achieve the same beauty.
[0027] As can be seen from the above technical solution, the speaker of the present specification extends outward from part of the side wall of the sound cavity body 10 and bends to form a reflex tube 14, one end of the reflex tube 14 is connected to the first sound cavity 11, and the other end of the reflex tube 14 passes through the side wall of the sound cavity body 10 and extends into the first sound cavity 11 and is connected to the first sound outlet 12. In this way, the inside and outside of the sound cavity body are connected through the reflex tube 14, thereby forming a reflex speaker structure similar to a Klein bottle, such as Figure 2 As shown, the inverted tube 14 can play the role of guiding sound, which not only optimizes the appearance of the speaker, but also shows its unique shape and aesthetic value. In addition, when the sound module 20 is working, the air inside the sound cavity body 10 resonates with the air in the inverted tube 14 at the corresponding tuning frequency, and the inverted tube 14 radiates low-frequency sound waves, which are superimposed with the sound waves radiated by the sound module 20 in front, so that the low-frequency effect is enhanced.
[0028] In some optional embodiments, the part of the inverted tube 14 exposed from the sound cavity body 10 and the second sound outlet 13 are located on different sides of the sound cavity body 10, so that the inverted tube 14 will not block the sound module 20, and the sound effect is better. In this embodiment, the part of the inverted tube 14 exposed from the sound cavity body 10 and the second sound outlet 13 are located on opposite sides of the sound cavity body 10. Figure 1 In the figure, the second sound outlet 13 is located on the left side of the sound cavity body 10. The part of the inverted tube 14 exposed from the sound cavity body 10 is located on the right side of the sound cavity body 10. The first sound outlet 12 is located at the bottom of the sound cavity body 10. It should be noted that, under the condition of satisfying the acoustic design and not affecting the sound effect, the part of the inverted tube 14 exposed from the sound cavity body 10 and the second sound outlet 13 can also be located on the same side of the sound cavity body 10.
[0029] like Figure 1As shown, in some optional embodiments, the sound module 20 may include a speaker 21, and the speaker 21 is installed at the second sound outlet 13. In this way, part of the sound waves emitted by the speaker 21 can be directly transmitted from the second sound outlet 13, and the other part can resonate with the air in the inverted tube 14 through the air inside the sound cavity body 10, and the low-frequency sound waves are radiated from the first sound outlet 12 by the inverted tube 14, and are superimposed with the sound waves radiated from the second sound outlet 13 in front, so that the low-frequency effect is enhanced.
[0030] Furthermore, the sound box may also include a first sealing member, which is sealed between the speaker 21 and the second sound outlet 13 to achieve sealing between the sound module 20 and the sound cavity body 10 to ensure the sound effect. Optionally, the first sealing member may be made of EVA (Ethylene Vinyl Acetate Copolymer) material, which has good sealing performance.
[0031] See also Figure 3 As shown, in some optional embodiments, the sound module 20 may include a base 22 and a speaker 21, and the base 22 is installed at the second sound outlet 13. The base 22 has a second sound cavity 23 connected to the first sound cavity 11, and the side wall of the base 22 is provided with a third sound outlet 24 connected to the second sound cavity 23, and the speaker 21 is installed at the third sound outlet 24. Optionally, the base 22 can be integrally formed with the sound cavity body 10 for easy processing.
[0032] So, compared to Figure 1 In the embodiment, after adding the base 22, the sound cavity body 10 can be turned over, which can change the appearance of the speaker and the position and sound direction of each sound outlet, so as to experience different appearance effects and sound effects. A part of the sound waves emitted by the speaker 21 can be directly transmitted from the third sound outlet 24, and the other part can resonate through the air inside the second sound cavity 23, the sound cavity body 10 and the air in the inverted tube 14, and the low-frequency sound waves are radiated from the first sound outlet 12 by the inverted tube 14, which are superimposed with the sound waves radiated from the third sound outlet 24 in front, so that the low-frequency effect is enhanced.
[0033] Furthermore, the sound box may further include a second sealing member, which is sealed and connected between the speaker 21 and the third sound outlet 24. The sealing between the speaker 21 and the base 22 is achieved to ensure the sound effect. Optionally, the second sealing member may be made of EVA (Ethylene Vinyl Acetate Copolymer) material, which has good sealing performance.
[0034] In some optional embodiments, the inverted tube 14 includes a first tube body 141 located outside the sound cavity body 10 and a second tube body 142 located inside the sound cavity body 10, the second tube body 142 and the first tube body 141 are integrally formed, the first tube body 141 is connected to the first sound cavity 11, and the second tube body 142 is connected to the first sound outlet 12. The first tube body 141 and the second tube body 142 are arc-shaped structures with opposite arc mouth directions, thus forming an appearance effect similar to a Klein bottle.
[0035] Furthermore, the portion of the first tube body 141 close to the first sound cavity 11 is in a trumpet-shaped structure, and the tube diameter of the trumpet-shaped structure gradually increases in the direction close to the first sound cavity 11. The portion of the second tube body 142 close to the first sound outlet 12 is in a trumpet-shaped structure, and the tube diameter of the trumpet-shaped structure gradually increases in the direction close to the first sound outlet 12. In this way, the portion of the inverted tube 14 close to the first sound cavity 11 and the first sound outlet 12 is in a trumpet-shaped structure, and the closer it is to the first sound cavity 11 and the first sound outlet 12, the better sound wave radiation effect can be achieved, and the acoustic effect can be improved.
[0036] In some optional embodiments, at least one of the sound cavity body 10 and the inverted tube 14 is a transparent material structure, and the speaker may further include a lighting module, which is arranged on the sound cavity body 10 or the sound module 20. In this way, the lighting module can achieve lighting effects of different colors, and reflect the color effect through the transparent sound cavity body 10 or the inverted tube 14, forming an acoustically visualized screenless speaker, achieving the effects of structural design visualization, audio signal visualization, and sound wave visualization. In this embodiment, the sound cavity body and the guide hanger are both transparent material structures. It should be noted that when the sound module includes a base, the base can also be a transparent material structure to achieve a fully transparent visualization effect. Optionally, the sound cavity body, the inverted tube, and the base can be made of transparent glass or transparent plastic.
[0037] It should be noted that in order to achieve better acoustic effects, the acoustic volumes of the sound cavity body and each sound cavity of the base and the diameter and length of the bass reflex tube can be adjusted as needed, and the overall appearance remains unchanged, and this manual does not impose any restrictions on this.
[0038] See also Figure 4 As shown, the passive sound cavity of the speaker in this manual is tested, and the acoustic design parameter Fb meets the debugging requirements. Figure 5 As shown, the Klein bottle-like bass reflex speaker structure design of the speaker of this manual (the upper lines in the figure) has a significantly enhanced low-frequency effect at 60-200Hz compared to the traditional closed-box design (the lower lines in the figure).
[0039] The above description is only a preferred embodiment of this specification and is not intended to limit this specification. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this specification should be included in the scope of protection of this specification.
