In addition, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0028] See also Figures 4 to 7, an embodiment of the sound device provided by the present invention is now described. The sound device includes a box, a sound-emitting component and a sound-emitting cavity 11 arranged in the box, and the sound-emitting component is located in the sound-emitting cavity 11. The box is also provided with a primary phase-conducting structure 3 and a secondary phase-conducting structure 21 for non-linear air conduction, and the primary phase-conducting structure 3 is used to conduct the secondary phase-conducting structure 21 with the sound-emitting cavity 11. The secondary phase-conducting structure 21 has two openings, namely a first opening 212 and a second opening 211 opposite to the first opening 212, the first opening 212 is used to communicate with the outside, and the second opening 211 is used to communicate with the primary phase-conducting structure 3.

[0029] The primary phase-conducting structure 3 and the secondary phase-conducting structure 21 can be conventional sound-conducting and air-conducting structures such as phase-conducting tubes or channels. The secondary phase-conducting structure 21 is a phase-conducting structure for non-linear air conduction, i.e., the communication path between the first opening 212 and the second opening 211 in the secondary phase-conducting structure 21 is non-linear (may be a folded line or arc-shaped communication path), and sound waves propagate non-linearly in the secondary phase-conducting structure 21.

[0030] The primary phase-conducting structure 3 is arranged along the substantially vertical direction (the direction substantially perpendicular to the bottom surface of the box), that is, the sound waves in the primary phase-conducting structure 3 are propagated along the substantially vertical direction, and the secondary phase-conducting structure 21 is arranged substantially perpendicular to the primary phase-conducting structure 3, that is, the secondary phase-conducting structure 21 is a non-linear phase-conducting structure arranged in a substantially horizontal plane or in a plane parallel to the substantially horizontal plane, and the sound waves in the secondary phase-conducting structure 21 propagate in a substantially horizontal plane or in a plane parallel to the substantially horizontal plane. The first opening 212 and the sound-emitting component are arranged on both sides of the box, that is, the first opening 212 and the position of the sound-emitting component on the box are arranged 180 degrees apart. Generally, the sound-emitting component is located on the front side of the box, facing the user, and the first opening 212 is located on the back side of the box, facing away from the user.

[0031] In this way, when the sound device provided by the embodiment of the present invention is used normally (the component is facing the user), the propagation of the sound wave in the phase-guide structure is first through the primary phase-guide structure 3 arranged in the vertical direction, and the phase of the sound wave is first adjusted to the vertical direction and parallel to the phase of the wall in the primary phase-guide structure 3, which is equivalent to weakening (adjusting) the sound wave, which is equivalent to reducing the influence of the wall and the distance factor of the wall on the sound device provided by the embodiment of the present invention in disguised form, and reducing the influence of the wall environment; when the sound wave passes through the secondary phase-guide structure 21, the phase of the sound wave is adjusted to be parallel to the bottom of the box (parallel to the horizontal plane), and because the secondary phase-guide structure 21 is a non-linear phase-guide structure, the phase-guided sound wave propagates non-linearly from the second opening 211 to the first opening 212, and the sound wave propagates from the first opening 212 with a certain angle, which also makes the sound wave of the secondary phase-guide structure 21 have a non-90-degree (vertical) incidence relationship with the vertically arranged wall (the phase-guided sound wave is not incident on the wall at 90 degrees), further reducing the influence of the wall and the distance of the wall on the phase-guided sound wave.

[0032] The sound device provided by the embodiment of the present invention weakens the guided phase sound waves by adding a vertically arranged primary phase-guide structure and a secondary phase-guide structure which is arranged perpendicular to the primary phase-guide structure and is non-linear in air conduction, and makes the sound waves have a non-vertical incidence relationship with the wall. Therefore, the sound device provided by the embodiment of the present invention combines the advantages of the front-guided phase and rear-guided phase sound structures with the ABR passive diaphragm guided phase sound, and reduces the influence of the wall and the distance from the wall on the sound effect while retaining the good low-frequency effect of the guided sound. In different environments with different distances from the wall, the music effect of the sound device provided by the embodiment of the present invention is almost completely consistent.

[0033] For further information, see Figures 4 to 5 In order to obtain better sound effects, the sound-generating component includes a tweeter 5 and a woofer 6 .

[0034] For further information, see Figures 4 to 5 For the convenience of use, the box body is also provided with a connection terminal 7 of the frequency divider.

[0035] Specifically, see Figures 6 to 8 As a specific embodiment of the sound device provided by the present invention, the secondary phase-conducting structure 21 is a folded line or arc-shaped phase-conducting structure, so that the sound wave airflow flows relatively smoothly in the secondary phase-conducting structure 21, and no sound wave airflow is generated at a 90-degree vertical incidence relationship with the wall.

[0036] For further information, see Figures 6 to 8 As a specific implementation of the audio device provided by the present invention, the secondary phase-conducting structure 21 is an air-conducting channel.

[0037] For further information, see Figures 4 to 5As a specific implementation of the audio device provided by the present invention, the secondary phase-conducting structure 21 is located below the primary phase-conducting structure 3.

[0038] For further information, see Figures 4 to 8 As a specific embodiment of the sound device provided by the present invention, the box includes a box body 1 and a lower bottom plate 2 arranged at the bottom of the box body 1, the sound cavity 11 is located in the box body 1, and the secondary phase-conducting structure 21 is formed by the box body 1 and the lower bottom plate 2. The secondary phase-conducting structure 21 is located at the lower part of the box as a whole, which is conducive to further reducing the influence of the wall and the distance from the wall on the sound effect.

[0039] For further information, see Figures 4 to 8 As a specific embodiment of the audio device provided by the present invention, a groove can be provided on the lower bottom plate 2, and the groove and the bottom of the box body 1 are enclosed together to form a secondary phase-conducting structure 21. An opening is provided at the bottom of the box body 1 and is connected to the secondary phase-conducting structure 21, and the primary phase-conducting structure 3 is inserted into the opening and communicated with the opening.

[0040] For further information, see Figures 4 to 8 , a breathable dustproof mesh plug 4 is provided at the first opening 212. The so-called breathable dustproof mesh plug 4 can be a breathable sponge material component, which is provided at the first opening 212. The interior of the ordinary phase-conducting structure is connected to the outside atmosphere. When the power is high and the dynamic is large, the control force is insufficient, and secondary harmonic distortion will be generated. In the embodiment of the present invention, a breathable dustproof mesh plug 4 with a certain air permeability and airflow resistance is filled at the first opening 212, so that the first phase-conducting structure 3 and the secondary phase-conducting structure 21 are not completely connected to the outside atmosphere. While ensuring the control force of high-power and high-dynamic music playback, the secondary harmonic distortion generated inside is reduced, so that the audio device provided by the embodiment of the present invention does not need to add electronic components, and the low-frequency performance is dynamic, powerful and elastic, and the sound field is full.

[0041] Preferably, as a specific implementation of the audio device provided by the present invention, the breathable dustproof mesh plug 4 is a 20-40 ppi (par per inch, sponge per square inch) component.

[0042] Furthermore, as a specific implementation of the audio device provided by the present invention, the primary phase-conducting structure 3 is a paper round tube phase-conducting component, that is, the primary phase-conducting structure 3 is a traditional phase-conducting tube, but is made of paper material, which is more environmentally friendly and has a low manufacturing cost.

[0043] Furthermore, as a specific implementation of the audio device provided by the present invention, the lower base plate 2 is connected to the box body 1 by threads, which makes it easy to install and replace the breathable dustproof mesh plug 4.

[0044] For further information, see Figures 6 to 8 As a specific embodiment of the audio device provided by the present invention, the first opening 212 and the second opening 211 are respectively located at the two ends of the secondary phase-conducting structure 21, and the opening cross-sectional area of ​​the second opening 211 is larger than the opening cross-sectional area of ​​the first opening 212, so that the sound wave airflow flows more smoothly from the second opening 211 to the first opening 212, and no noise is generated, thereby improving the low-frequency effect.
