DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] Specifically, a mounting structure 200 is provided on the top end face of the subwoofer enclosure 100. The mounting structure 200 is used for rotatable connection with at least two midrange / high-frequency enclosures 300, so that each midrange / high-frequency enclosure 300 can rotate on the subwoofer enclosure 100. It can be understood that the midrange / high-frequency enclosure 200 can rotate on the subwoofer enclosure 100 in a circular plane, or it can be configured to rotate in all directions through a structure similar to a ball joint.

[0049] It is worth mentioning that by stacking at least two mid-high speaker bodies 300 on one bass speaker body 100 in a three-dimensional manner and by rotatingly connecting each mid-high speaker body 300 through the mounting structure 200, the distance between the mid-high speaker body 300 and the bass speaker body 100 can be changed, thereby simplifying the complex spatial adjustment operation of the original sound wall in different sound effect modes, i.e., simplifying the operation of continuously moving and moving the original sound wall in different modes to adjust the relative displacement of the bass speaker body and the strip-shaped box, effectively solving the shortcomings of the unadjustable or scattered placement of the left and right channel speaker distance without effect, forming a three-dimensional immersive sound effect, i.e., the user can realize sound adjustment and correction function by rotating the extension angle of each mid-high speaker body 300, optimize sound playing effect, calibrate sound, and feel different sound effects. In a large space, it can be unfolded and used to cooperate with the movie sound effect algorithm to produce good audio-visual effect; in a small space, it can be folded and used to cooperate with the music sound effect algorithm to produce a powerful bass effect. The bass speaker body 100 and the mid-high speaker body 300 are designed to be convenient to store and fully save space, and transportation is more convenient. In this way, the practicability of the stereo speaker 10 is effectively increased.

[0050] It can be understood that the number of mid-high speaker bodies 300 can be selected but is not limited to three, four, and six. When the mid-high speaker body 300 is set to multiple, the multiple mid-high speaker bodies 300 can be selected but are not limited to being arranged side by side, such as two by two or in a linear arrangement, and each mid-high speaker body 300 is rotatably connected to the mounting structure 200 and is stationary when rotated to a specified position. Among them, the arrangement of each mid-high speaker body 300 is set according to the actual production situation, and only needs to ensure that the distance between the mid-high independent cavity and the bass cavity can be freely adjusted; and the rotatable connection mode can be selected but is not limited to tight rotatable connection, i.e., each mid-high speaker body 300 is displaced when subjected to a certain pushing force, and is stably stationary under the action of friction without external force.

And the rotation guide rod 310 and the straight guide rod 320 can be fixed on the mounting seat to prevent the rotation guide rod 310 and the straight guide rod 320 from being separated from the mounting seat.

[0065] In embodiment 3, the structure matched and connected between the mounting structure 200 and the mid-high speaker box 300 is a center shaft structure, and the specific structure is as follows: Figure 3 Figure 3 In the coordinate system of

[0066] In embodiment 3

[0067] This embodiment is similar to embodiment 2, and the difference is that, as shown in Figure 3 in this embodiment, the structure matched and connected between the mounting structure 200 and the mid-high speaker box 300 is a center shaft structure, and the specific structure is as follows:

[0068] The mounting seat of the mounting structure 200 is provided with a center shaft 215, and the mid-high speaker box 300 is connected with a rotating shaft 330, and the rotating shaft 330 is sleeved on the center shaft 215 and is rotationally connected with the outer surface of the center shaft 215, so as to drive the mid-high speaker box 300 to rotate on the mounting structure 200.​

[0069] Specifically, two center shafts 215 are arranged on the rear surface of the mounting seat, and a receiving groove matched with the rotating shaft 330 is arranged on the mid-high frequency speaker body 300 to accommodate the rotating shaft 330. The rotating shaft 330 is installed in the receiving groove, and the inner ring surface of the rotating shaft 330 is rotationally connected with the outer ring surface of the center shaft 215, so that the mid-high frequency speaker body 300 can be driven to rotate by rotating the rotating shaft 330 around the center shaft 215.

[0070] In order to facilitate the control of the static and motion of the mid-high frequency speaker body 300, as shown in some embodiments, the mounting structure 200 is provided with a locking member 400 for locking each mid-high frequency speaker body 300. Figure 3

[0071] Specifically, the locking member 400 is locked to control the motion state of the mid-high frequency speaker body 300. The mounting structure 200 is provided with a through hole along the Y-axis direction, and a plurality of pin holes are arranged on the mid-high frequency speaker body 300. The locking member 400 can be a pin, which passes through the through hole from the front and is connected with the side wall of a pin hole to fix the mid-high frequency speaker body 300 on the mounting structure 200. The pin hole can be arranged at a corresponding position to enable the mid-high frequency speaker body 300 to be fixed and static when forming a 90° angle and a 180° angle with the bass speaker body 100. The specific arrangement of the pin hole is subject to actual production requirements and is not limited herein.

[0072] In addition, in the present embodiment, the limiting member is arranged according to the specific production situation, as long as it can ensure that the mid-high frequency speaker body 300 rotates with the mounting structure 200 while avoiding the mid-high frequency speaker body 300 from separating from the mounting structure 200. For example, a detent structure can be arranged between the center shaft 215 and the rotating ring to prevent the mid-high frequency speaker body 300 from separating from the mounting structure 200 in the Y-axis direction. The mounting structure 200 is provided with a silica gel ring, and the silica gel ring is sleeved on the outer circumferential side of the center shaft 215 to buffer the mid-high frequency speaker body 300.

When rotating, the mid-high frequency box body 300 can be pulled up and rotated against the spring tension, and in the folded state, the tension of the spring tightly abuts the bottom end face of the mid-high frequency box body 300 and the top end face of the bass box body 100. In this way, through the structure of the spring center shaft, the space occupied by the mid-high frequency box body 300 and the bass box body 100 in the folded state can be effectively reduced, thereby facilitating storage.

[0077] It can be understood that the structure without gap between the mid-high frequency box body 300 and the bass box body 100 is not limited here, and only needs to ensure that the space occupied by the entire sound box can be reduced to a certain extent. For example, the structure of two magnetic members magnetically attracted close to each other can also be provided. When the two magnetic members are attracted to each other, the mid-high frequency box body 300 is attracted to the bass box body 100 under the action of the magnetic force, and when an external force pulls apart the mid-high frequency box body 300, the mid-high frequency box body 300 can be rotated on the bass box body 100.

[0093] Embodiment 7

[0094] This embodiment is similar to Embodiment 6, and the difference is that, as shown in Figure 7 , in this embodiment, the structure for connecting the mounting structure 200 and the mid-high speaker body 300 is a center shaft structure, and the specific structure is as follows:

[0095] The center shaft 215 is arranged on the mid-high speaker body 300, and the rotating shaft 330 is connected to the mounting seat of the mounting structure 200, and the rotating shaft 330 is sleeved on the center shaft 215 and is in rotating connection with the outer side surface of the center shaft 215, so as to drive the mid-high speaker body 300 to rotate on the mounting structure 200.

The rotating shaft 330 is installed in the accommodating groove, and the inner ring surface of the rotating shaft 330 is in rotating connection with the outer ring surface of the center shaft 215, so that the mid-high speaker body 300 can be driven to rotate by the rotating shaft 330 rotating around the center shaft 215.

[0097] In order to facilitate the control of the static and motion of the mid-high speaker body 300, as shown in Figure 7 , in some embodiments, the locking member 400 for locking each mid-high speaker body 300 is arranged on the mounting structure 200.

[0098] Specifically, the locking member 400 is locked, so as to control the motion state of the mid-high speaker body 300. The mounting structure 200 is provided with a through hole in the Y-axis direction, and a plurality of pin holes are arranged on the mid-high speaker body 300 in cooperation. The locking member 400 can be selected but is not limited to a latch, and the latch passes through the through hole from the front and is connected with the side wall of a pin hole, so as to fix the mid-high speaker body 300 on the mounting structure 200. Among them, the pin hole can be arranged at the corresponding position, so that the mid-high speaker body 300 can be fixed and static when forming a 90° angle and a 180° angle with the bass speaker body 100. The specific arrangement of the pin hole is subject to the actual production demand, and is not limited here.

[0099] In addition, in the embodiment, the limiting member is set according to the specific production situation, as long as the rotation between the mid-high speaker body 300 and the mounting structure 200 can also avoid the mid-high speaker body 300 from separating from the mounting structure 200, for example, a clamping structure can be arranged between the central shaft 215 and the rotating ring to avoid the mid-high speaker body 300 from separating from the mounting structure 200 in the Y-axis direction. And the mounting structure 200 is provided with a silica gel ring, and the silica gel ring is sleeved on the outer circumferential side of the central shaft 215 to buffer the mid-high speaker body 300.

[0102] Embodiment 8

[0103] The embodiment is a further embodiment of embodiment 7, in which the structure of the mounting structure 200 and the mid-high speaker body 300 is arranged as a spring central shaft structure.

[0104] Specifically, compared with the central shaft structure, the spring central shaft structure increases a spring fixing shaft on the bass speaker body 100, the spring fixing shaft is provided with a spring, the spring is connected with the mid-high speaker body 300, and the spring avoids each pin hole. When rotating, the mid-high speaker body 300 can be pulled up and rotated against the spring tension, and in the folded state, the tension of the spring tightly fits the bottom end face of the mid-high speaker body 300 with the top end face of the bass speaker body 100. In this way, through the structure of the spring central shaft, the bottom end of the mid-high speaker body 300 in the folded state and the top end of the bass speaker body 100 can be gapless, thereby effectively reducing the occupied space and facilitating storage.

[0105] It can be understood that the structure between the mid-high speaker body 300 and the bass speaker body 100 is not limited here, as long as it can reduce the space occupied by the entire speaker to a certain extent. For example, it can also be arranged as a structure of two magnetic members magnetically attracted close to each other. When the two magnetic members are attracted to each other, the mid-high speaker body 300 is close to the bass speaker body 100 under the action of the magnetic force, and when the mid-high speaker body 300 is pulled apart by an external force, the mid-high speaker body 300 can be rotated on the bass speaker body 100.

[0106] Example 9, Appendix Figure 12 and attached Figure 13 In the middle, for reference Figure 12 The coordinate system is defined with the X-axis pointing to the right, the Y-axis pointing to the front, and the Z-axis pointing to the top.

[0107] Example 9

[0108] This embodiment is similar to embodiment 6, except that, as follows: Figure 12 and Figure 13 As shown, in this embodiment, the subwoofer enclosure 100 and the mounting structure 200 are at least partially facing each other in the horizontal direction.

[0109] Specifically, the subwoofer enclosure 100 has an open front side, and the mounting structure 200 is a front panel that covers the open front side of the subwoofer enclosure 100. Two arc-shaped grooves 211 and two straight grooves 212 are formed on the bottom of the front panel. After the rotating guide rod 310 and the straight guide rod 320 are fitted onto the front panel, the screws are tightened. A silicone collar is positioned at the front end of the groove so that the screw engages with the rear surface of the silicone collar. In this way, the two mid-high frequency enclosures 300 are rotatably connected to the front side of the subwoofer enclosure 100, with their axis positioned below the front panel.

[0110] Example 10, Appendix Figure 14 In the middle, for reference Figure 14 The coordinate system is defined with the X-axis pointing to the right, the Y-axis pointing to the front, and the Z-axis pointing to the top.

[0111] Example 10

[0112] This embodiment is similar to embodiment 9, except that, as follows: Figure 14 As shown, in this embodiment, the structure connecting the mounting structure 200 and the mid-high frequency speaker enclosure 300 is set as a central axis structure, and its specific structure is as follows:

[0113] A central shaft 215 is provided on the mid-high frequency speaker enclosure 300, and a rotating shaft 330 is connected to the front plate of the mounting structure 200. The rotating shaft 330 is sleeved on the central shaft 215 and rotatably connected to the outer surface of the central shaft 215 to drive the mid-high frequency speaker enclosure 300 to rotate on the mounting structure 200.

[0114] Specifically, a central shaft 215 is provided on the rear side of the mid-high frequency speaker enclosure 300, and a receiving groove is provided on the bottom front side of the front panel to accommodate the rotating shaft 330. The rotating shaft 330 is installed in the receiving groove, and the inner ring surface of the rotating shaft 330 is rotatably connected to the outer ring surface of the central shaft 215. Thus, the mid-high frequency speaker enclosure 300 can be driven to rotate by rotating the rotating shaft 330 around the central shaft 215.

[0115] In order to facilitate the control of the static and movement of the mid-high speaker body 300, as shown in the drawings, in some embodiments, the mounting structure 200 is provided with locking members 400 for locking each mid-high speaker body 300. Figure 3

[0116] Specifically, through the locking action of the locking member 400, the movement state of the mid-high speaker body 300 can be controlled. The mounting structure 200 is provided with a through hole along the Y-axis direction, and the mid-high speaker body 300 is provided with a plurality of pin holes. The locking member 400 can be, but is not limited to, a latch. The latch passes through the through hole from the front and is connected with the side wall of a pin hole, so as to fix the mid-high speaker body 300 on the mounting structure 200. Among them, the pin hole can be arranged at the corresponding position, so that the mid-high speaker body 300 can be fixed and static when forming a 90° angle and a 180° angle with the bass speaker body 100. The specific arrangement of the pin hole is subject to the actual production demand and is not limited here.

[0117] In addition, in the present embodiment, the limiting member is arranged according to the specific production condition, as long as it can ensure that the mid-high speaker body 300 rotates with the mounting structure 200 while avoiding the mid-high speaker body 300 from separating from the mounting structure 200. For example, a clamping structure can be arranged between the center shaft 215 and the rotating ring to avoid the mid-high speaker body 300 from separating from the mounting structure 200 in the Y-axis direction. The mounting structure 200 is provided with a silica gel ring, and the silica gel ring is sleeved on the outer circumferential side of the center shaft 215 to buffer the mid-high speaker body 300.

[0118] In this way, through the cooperative rotation of the center shaft 215 and the rotating shaft 330, the mid-high speaker body 300 can complete the rotation of 90° to 180°, and the mid-high speaker body 300 is fixed in the required direction through the latch.

[0119] In addition, the cross-sectional shape of the end of the mid-high speaker body 300 close to the bass speaker body 100 is arranged as a semicircular arc. In order to facilitate the rotation of the mid-high speaker body 300 on the bass speaker body 100.

[0120] Embodiment 11

[0121] The present embodiment is a further embodiment of embodiment 10. In the present embodiment, the structure of the mounting structure 200 and the mid-high speaker body 300 is arranged as a spring center shaft structure.

[0122] ​Specifically, compared with the center shaft structure, the spring center shaft structure adds a spring fixing shaft on the front plate of the mounting structure 200, the spring fixing shaft is provided with a spring, the spring is connected with the mid-high pitch box body 300, and the spring avoids each pin hole. When rotating, the mid-high pitch box body 300 can be pulled up and rotated against the spring tension. In the folded state, the spring tension sets the bottom end face of the mid-high pitch box body 300 and the bottom end face of the bass box body 100 to be flush. In this way, through the structure of the spring center shaft, the bottom end of the mid-high pitch box body 300 and the bottom end of the bass box body 100 in the folded state are flush, thereby effectively reducing the occupied space and facilitating storage.

[0123] It can be understood that the structure without gap between the mid-high pitch box body 300 and the bass box body 100 is not limited here, and only needs to ensure that the space occupied by the entire sound box can be reduced to a certain extent. For example, it can also be provided as a structure in which two magnetic members are magnetically attracted close to each other. When the two magnetic members are attracted to each other, the mid-high pitch box body 300 is close to the bottom end of the bass box body 100 under the action of the magnetic force, so that the bottom end of the mid-high pitch box body 300 and the bottom end of the bass box body 100 are flush with each other. When an external force pulls apart the mid-high pitch box body 300, the mid-high pitch box body 300 can be rotated on the bass box body 100.

[0124] Embodiment 12, attached Figure 15 to the attached Figure 18 Reference Figure 15 The coordinate system is taken, the direction indicated by the X-axis arrow is right, the direction indicated by the Y-axis arrow is front, and the direction indicated by the Z-axis arrow is up.

[0125] Embodiment 12
