[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0034] In the following examples and drawings, the coordinate system of Figure 1 is used, with the direction indicated by the arrow of the X axis being right, the direction indicated by the arrow of the Y axis being front, and the direction indicated by the arrow of the Z axis being up.

[0035] Example 1:

[0036] As shown in Figures 1 to 3 , in the present embodiment, a single-axis speaker box 10 includes a bass box 100, a mid-high frequency box 200 and a mounting member 300. The mounting member 300 is connected with the bass box 100, the mid-high frequency box 200 is connected with the mounting member 300, and the mid-high frequency box 200 is cooperatively rotated on the bass box 100 through the mounting member 300, and is relatively stationary with the bass box 100 when reaching the required position.

[0037] Specifically, the low-frequency speaker box 100 is connected with the mounting member 300, and the mid-high-frequency speaker box 200 is connected with the mounting member 300, so that the mid-high-frequency speaker box 200 can rotate on the low-frequency speaker box 100 through the mounting member 300. It can be understood that the rotation of the mid-high-frequency speaker box 200 on the low-frequency speaker box 100 can be rotation on a circumferential plane, or can be rotation in the four directions through a structure similar to a spherical hinge.

[0038] It is worth noting that through the connection of the mounting member 300, the mid-high-frequency speaker box 200 can rotate on the low-frequency speaker box 100, and can also be stationary relative to the low-frequency speaker box 100 when rotated to the corresponding position, which is convenient for the consumer to adjust and use. That is, the consumer only needs to rotate the mid-high-frequency speaker box 200 by pushing it, so as to adjust the relative position of the low-frequency speaker box 100 and the mid-high-frequency speaker box 200, so as to adjust different sound effects. Therefore, the sound effect adjustment operation mode of the single-axis speaker 10 is more simple.

[0039] In this way, when the extension angle of the mid-high-frequency speaker box 200 is controlled, the distance between the mid-high-frequency independent cavity and the low-frequency cavity can be adjusted, which simplifies the complex space adjustment operation of the original sound wall in different sound effect modes, that is, simplifies the operation of constantly moving and moving the low-frequency speaker box 100 and the strip-shaped box in different modes to adjust the relative displacement of the low-frequency speaker box 100 and the strip-shaped box. Effectively solve the shortcomings that the distance between the left and right channels cannot be adjusted or scattered and placed without effect, form a three-dimensional immersive sound effect sound field, that is, the user can realize sound adjustment and correction function by changing the extension angle of the mid-high-frequency speaker box 200, optimize sound playing effect, calibrate sound, and feel different sound effects. Different audio-visual effects can also be generated according to the sound effect algorithm.

[0040] Embodiment 2

[0041] This embodiment is a further implementation of embodiment 1, as shown in Figures 1 to 3 In this embodiment, the low-frequency speaker box 100 is connected with the positioning member 110, and the mounting member 300 is connected with the positioning member 110.

[0042] Specifically, a positioning member 110 is protrudedly arranged on the top rear side of the bass box body 100, so that the mid-high box body 200 can be circumferentially rotated on the front side of the positioning member 110, thereby realizing the rotation of the bass box body 100. A rotation space cooperating with the mid-high box body 200 is formed between the adjacent plane of the bass box body 100 and the positioning member 110, and the mid-high box body 200 rotates in the rotation space. That is, the top end of the bass box body 100 and the front side of the positioning member 110 form a rotation space, and the mid-high box body 200 rotates at the end of the positioning member 110 away from the bass box body 100, so that the mid-high box body 200 rotates on the top end of the positioning member 110 and can rotate in the middle of the positioning member 110.

[0043] In order to facilitate the rotation of the mid-high box body 200 on the bass box body 100, as shown in Figures 1 to 3 , in some embodiments, the mid-high box body 200 is symmetrically connected to the bass box body 100 by the mounting member 300.

[0044] Specifically, by connecting the middle of the mid-high box body 200 to the middle of the positioning member 110, that is, the midline of the mid-high box body 200 can coincide with the midline of the positioning member 110, so that the mid-high box body 200 can be symmetrically distributed on the positioning member 110, which facilitates the rotation of the mid-high box body 200, avoids the single-axis speaker 10 from being offset due to uneven weight when placed, and also avoids the heavy end from having a downward inclination due to the excessive weight of the one end.

[0045] In order to ensure good sound effect, in some embodiments, the plurality of sound emitting members in the mid-high box body 200 are symmetrically arranged relative to the bass box body 100.

[0046] Specifically, the sound emitting member can be selected but not limited to a loudspeaker (not shown in the figure), two loudspeakers are arranged in the two ends of the mid-high box body 200, and are symmetrically arranged relative to the midline of the bass box body 100, so that when the mid-high box body 200 is rotated to be perpendicular to the bass box body 100, a symmetrical sound effect on both sides can be formed, thereby forming a better audio-visual effect.

[0047] In order to facilitate the storage of the single-axis speaker 10, as shown in Figure 1 and Figure 3 , in some embodiments, the positioning member 110 is connected to one end of the bass box body 100, and when the mid-high box body 200 is rotated on one side of the positioning member 110 by the mounting member 300, the width of the positioning member 110 and the width of the mid-high box body 200 are less than or equal to the width of the bass box body 100.

[0048] Specifically, the medium-high sound box 200 rotates on the front side of the positioning member 110 and covers the front side of the positioning member 110. In this way, the medium-high sound box 200 can completely cover the front side of the positioning member 110 during rotation, and because the positioning member 110 and the low sound box 100 are arranged in the same width, the required storage space of the single-shaft sound box 10 can be effectively reduced, and the single-shaft sound box 10 is convenient to store.

[0049] In order to facilitate the storage of the single-shaft sound box 10, as shown in Figure 1 and Figure 2 In some embodiments, the positioning member 110 is connected to one end of the low sound box 100, and when the medium-high sound box 200 rotates on one side of the positioning member 110 through the mounting member 300, the thickness of the low sound box 100 is greater than or equal to the distance between the other side of the positioning member 110 and the outer side surface of the medium-high sound box 200 away from the positioning member 110.

[0050] Specifically, by arranging the distance between the rear side of the positioning member 110 and the front side of the medium-high sound box 200 to be less than or equal to the thickness of the low sound box 100, the single-shaft sound box 10 can be placed in a gap with the same width as the low sound box 100, thereby reducing the required space volume for storing the single-shaft sound box 10 as a whole, and facilitating the storage of the single-shaft sound box 10 as a whole.

[0051] In addition, the specific size of the low sound box 100, the medium-high sound box 200 and the positioning member 110 is subject to actual production needs and is not limited herein.

[0052] In order to facilitate the use of the single-shaft sound box 10, in some embodiments, the included angle between the medium-high sound box 200 and the low sound box 100 during rotation is 90° and 180°.

[0053] Specifically, when the medium-high sound box 200 and the low sound box 100 are stored, the angle between them is 180°, so that the whole is arranged in a vertical one-word type, thereby making the space volume occupied by the single-shaft sound box 10 smaller, facilitating storage, and when in use, the angle between the medium-high sound box 200 and the low sound box 100 can be arranged as 90°.

[0054] In order to facilitate the connection of the low sound box 100 and the medium-high sound box 200, as shown in Figures 2 to 4 In some embodiments, the structure of the mounting member 300 and the low sound box 100 is arranged as an eccentric shaft structure, and the specific structure is as follows:

[0055] The positioning member 110 is provided with an arc-shaped track 111 and a straight track 112. The straight track 112 is arranged outside the circumferential track and along the radial direction of the circumferential track, and is arranged at the midline of the arc-shaped track 111. The mounting member 300 comprises an arc-shaped guide rod 310 and a straight guide rod 320. The arc-shaped guide rod 310 and the straight guide rod 320 are connected to the mid-high sound box body 200. When the straight guide rod 320 slides in the straight track 112, the corresponding arc-shaped guide rod 310 synchronously slides in the corresponding arc-shaped track 111, so as to drive the mid-high sound box body 200 to rotate on the positioning member 110.

[0056] Specifically, the positioning member 110 comprises a mounting seat. The arc-shaped track 111 and the straight track 112 are arranged on the front side of the mounting seat. The arc-shaped track 111 is a left partial of the upper half circle of the circumferential track. The arc-shaped guide rod 310 and the straight guide rod 320 are arranged on the mid-high sound box body 200. The arc-shaped guide rod 310 is inserted into the arc-shaped track 111, and the straight guide rod 320 is inserted into the straight track 112, so as to be connected with the positioning member 110. Thus, the mid-high sound box body 200 can be driven to rotate on the positioning member 110 by eccentric rotation. In this way, in the initial state, the mid-high sound box body 200 is vertically arranged on the positioning member 110. At this time, the straight guide rod 320 is at the bottom end of the straight track 112, and the arc-shaped guide rod 310 is at the bottom end of the arc-shaped track 111. When it is needed to be unfolded, the straight guide rod 320 slides obliquely upward from the bottom end of the straight track 112, and the arc-shaped guide rod 310 slides from the bottom end to the top end of the arc-shaped track 111. When the arc-shaped guide rod 310 slides to the middle part of the arc-shaped track 111, the straight guide rod 320 slides to the top end of the straight track 112. The arc-shaped guide rod 310 continues to slide upward, and the straight guide rod 320 slides obliquely downward from the top end of the straight track 112, until the mid-high sound box body 200 and the low sound box body 100 are arranged in a T shape. In this way, the arc-shaped guide rod 310 slides to the top end of the arc-shaped track 111, and the straight guide rod 320 slides to the bottom end of the straight track 112. The mid-high sound box body 200 is in the unfolded state. The eccentric shaft structure does not need to be designed to avoid clearance. When the mid-high sound box body 200 rotates, the relative position of the eccentric shaft moves to avoid interference. Figure 3 Figure 2

[0057] The connection between the sliding groove and the guide rod can be relatively close connection, so that the mid-high sound box body 200 is relatively stationary with the low sound box body 100 when reaching the corresponding position. That is, the positioning member 110 and the mid-high sound box body 200 can be stably stationary by the friction force under the action of no external force. In this way, the low sound box body 100, the positioning member 110 and the mid-high sound box body 200 are relatively stationary in the normal state. When subjected to a certain thrust, the mid-high sound box body 200 can rotate on the positioning member 110.

[0058] ​​It can be understood that the manner in which the mid-high speaker box 200 is relatively stationary with the bass speaker box 100 when reaching the required position is not limited herein, for example, the mid-high speaker box 200 can be locked by a locking member when rotating to the corresponding position, and the manner in which the locking member locks the mid-high speaker box 200 is known to those skilled in the art and can be implemented, and is not described in detail in the present embodiment.

[0059] In order to prevent the bass speaker box 100 from easily separating from the mid-high speaker box 200, as shown in some embodiments, a separation-preventing limiting member 400 is arranged between the mounting member 300 and the bass speaker box 100 to limit the mid-high speaker box 200 from separating from the bass speaker box 100. Figures 2 to 4

[0060] Specifically, the number of the separation-preventing limiting members 400 can be selected but is not limited to two, the upper separation-preventing limiting member 400 is arranged at one end of the straight track 112 close to the mid-high speaker box 200, i.e., the front end of the straight track 112, and the lower separation-preventing limiting member 400 is arranged at one end of the arc-shaped track 111 close to the mid-high speaker box 200, i.e., the front end of the arc-shaped track 111, and the front end faces of the two separation-preventing limiting members 400 are flush with the front side surface of the positioning member 110. The separation-preventing limiting member 400 can be selected but is not limited to a silica gel sleeve, which is sleeved on the periphery of the corresponding sliding groove, and the rear ends of the straight guide rod 320 and the arc guide rod 310 of the mid-high speaker box 200 are connected with screws for clamping and limiting, so as to clamp the rear end faces of the silica gel sleeves on the corresponding sliding grooves through the screws, thereby avoiding the straight guide rod 320 and the arc guide rod 310 from separating from the corresponding sliding grooves, and further locking the mid-high speaker box 200 on the positioning member 110. In this way, the separation-preventing limiting member 400 can achieve the purpose of shockproof and anti-loosening.

[0061] Embodiment 3

[0062] The present embodiment is similar to embodiment 2, and the difference lies in that, as shown in Figure 1 , Figure 5 and Figure 6 in the present embodiment, the structure of the mounting member 300 and the bass speaker box 100 is cooperatively connected in a center shaft structure, and the specific structure is as follows:

[0063] The positioning member 110 is provided with a center shaft 113, and the mounting member 300 includes a rotating shaft 330 connected to the mid-high speaker box 200, and the rotating shaft 330 is sleeved on the center shaft 113 and rotationally connected with the outer side surface of the center shaft 113 to drive the mid-high speaker box 200 to rotate on the positioning member 110.

[0064] ​Specifically, the middle of the top end of the mounting seat is provided with a central shaft 113, and the middle of the mid-high speaker body 200 is provided with an accommodating groove matched with the rotating shaft 330 to accommodate the rotating shaft 330. The rotating shaft 330 is installed in the accommodating groove, and the inner ring surface of the rotating shaft 330 is rotationally connected with the outer ring surface of the central shaft 113, so that the mid-high speaker body 200 can be driven to rotate by the rotating shaft 330 rotating around the central shaft 113.

[0065] In order to realize that the mid-high speaker body 200 is relatively stationary with the bass speaker body 100 when reaching the required position, as shown in Figure 1 , Figure 5 and Figure 6 indicated, in some embodiments, a locking piece 500 for fixing the mid-high speaker body 200 is arranged between the bass speaker body 100 and the mid-high speaker body 200.

[0066] Specifically, the mounting seat is provided with a through hole in the Y-axis direction, and a plurality of pin holes are matched and provided on the mid-high speaker body 200. The locking piece 500 can be selected but not limited to a latch, which passes through the through hole from the rear and is connected with the side wall of a pin hole to fix the mid-high speaker body 200 on the positioning piece 110. Among them, the pin holes can be arranged at corresponding positions to enable the mid-high speaker body 200 to be stationary and fixed when forming a 90° angle and a 180° angle with the bass speaker body 100. The specific arrangement of the pin holes is subject to actual production needs and is not limited here.

[0067] In addition, in the present embodiment, the anti-disengagement limiting piece 400 is arranged according to the specific production situation, as long as it can ensure that the mid-high speaker body 200 rotates while avoiding disengagement from the bass speaker body 100, for example, a detent structure can be arranged between the central shaft 113 and the rotating ring to avoid the mid-high speaker body 200 from disengaging from the positioning piece 110 in the Y-axis direction. A silica gel ring is arranged on the mounting seat and is sleeved on the outer circumferential side of the central shaft 113 to buffer the mid-high speaker body 200.

[0068] In order to facilitate the free rotation of the mid-high speaker body 200 on the positioning piece 110, as shown in Figure 1 and Figure 2 indicated, in some embodiments, an avoidance gap is arranged between the bass speaker body 100 and the mid-high speaker body 200.

[0069] Specifically, an avoidance gap can be arranged between the bottom end of the mid-high speaker body 200 and the top end of the bass speaker body 100, so as to avoid the interference of the bass speaker body 100 with the rotation of the mid-high speaker body 200, that is, to avoid the limiting effect of the bass speaker body 100 on the mid-high speaker body 200 during rotation, so that the mid-high speaker body 200 can freely rotate on the positioning piece 110.

[0070] It can be understood that the avoiding gap between the bass box body 100 and the mid-high box body 200 is subject to actual production requirements, which is not limited herein, and only needs to ensure that the mid-high box body 200 can be freely rotated.

[0071] In this way, through the cooperation rotation of the central shaft 113 and the rotating shaft 330, the mid-high box body 200 can complete the rotation of 90° to 180°, and the mid-high box body 200 is fixed in the required direction through the pin.

[0072] Embodiment 4

[0073] The embodiment is a further implementation manner of the embodiment 3, and in the embodiment, the structure of the cooperation connection between the mounting piece 300 and the bass box body 100 is provided as a spring central shaft structure.

[0074] Specifically, compared with the central shaft structure, a spring is connected on the mid-high box body 200 in the spring central shaft structure, and the spring avoids each pin hole setting, and when rotating, the mid-high box body 200 can be pulled up and rotated against the spring tension, so that the mid-high box body 200 can avoid interference through the spring contraction, and there is no need to design an avoiding gap. The tension of the spring tightly abuts the mid-high box body 200 and the bass box body 100 when being static. In this way, through the structure of the spring central shaft, there is no gap between the mid-high box body 200 and the top end of the bass box body 100, so that the occupied space is effectively reduced, and the practicability is higher.
