DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. The described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0038] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0039] Embodiments 1 to 3, attached Figure 1 to attached Figure 5 In the drawings, reference Figure 1The 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.

[0040] Example 1:

[0041] like Figure 1 As shown, this embodiment provides a stereo speaker 10, including: a bass enclosure 100 with a mounting structure 200; and at least two mid-high frequency enclosures 300, which are rotatably connected to the mounting structure 200 so that they can be closed or unfolded on the bass enclosure 100 and remain stationary when they reach a designated position.

[0042] 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.

[0043] It is worth noting that by stacking at least two mid-high frequency speaker enclosures 300 on a single bass speaker enclosure 100, and connecting each enclosure 300 via a rotating mounting structure 200, the distance between the mid-high frequency speaker enclosures 300 and the bass speaker enclosure 100 can be changed. This simplifies the complex spatial adjustment operations of traditional soundbars in different sound effect modes. Specifically, it simplifies the need for constant moving and adjusting the relative displacement of the bass speaker enclosure and the soundbar in different modes, effectively solving the shortcomings of non-adjustable speaker distances in the left and right channels or ineffective scattered placement. This creates a three-dimensional, immersive sound effect. Users can adjust and correct the sound by rotating the extension angle of each mid-high frequency speaker enclosure 300, optimizing sound playback and calibrating the sound to experience different sound effects. It can be deployed in large spaces, working with movie sound effect algorithms to produce excellent audiovisual effects; in small spaces, it can be folded up, working with music sound effect algorithms to produce a powerful and concentrated bass effect. The design of the woofer enclosure 100 and the mid-high frequency enclosure 300 is both convenient to store and saves space, making transportation easier. This effectively increases the practicality of the stereo speaker 10.

[0044] It can be understood that the number of the mid-high sound boxes 300 can be selected but is not limited to three, four and six, and when the mid-high sound boxes 300 are arranged in multiple, the multiple mid-high sound boxes 300 can be selected but are not limited to being arranged side by side, such as two by two or in a linear manner, and each mid-high sound box 300 is rotationally connected with the mounting structure 200 and is stationary when rotated to a specified position. Among them, the arrangement of each mid-high sound box 300 is set according to the actual production situation, and only needs to ensure that the distance between the mid-high sound independent cavity and the bass cavity can be freely adjusted; and the rotationally connected manner can be selected but is not limited to tight rotationally connected, that is, each mid-high sound box 300 is displaced when subjected to a certain pushing force, and is stably stationary under the action of friction without external force.

[0045] Embodiment 2

[0046] This embodiment is a further implementation of embodiment 1, as shown in Figure 1 In this embodiment, the mid-high sound boxes 300 are arranged in two, and the two mid-high sound boxes 300 are arranged side by side.

[0047] Specifically, the two mid-high sound boxes 300 are arranged on one side of the mounting structure 200, that is, the two mid-high sound boxes 300 are rotationally connected with the rear side surface of the mounting structure 200, so that the two mid-high sound boxes 300 are arranged on the top end of the bass box 100. Referring to Figure 1 When the two mid-high sound boxes 300 are in the folded state, the two mid-high sound boxes 300 are vertically arranged side by side on the bass box 100 along the Z-axis direction; referring to Figure 2 When the mid-high sound box 300 needs to be unfolded, one mid-high sound box 300 is unfolded on the bass box 100 and can be extended to the required angle and then stationary. It can be understood that Figure 2 only the unfolding of one side of the mid-high sound box 300 is shown, and both mid-high sound boxes 300 can be unfolded on the bass box 100 in actual use.

[0048] In order to facilitate the rotational connection of the two mid-high sound boxes 300 with the mounting structure 200, as shown in Figures 1 to 4 In some embodiments, the mounting structure 200 is arranged as a mounting seat, two arc-shaped sliding grooves 211 and two straight sliding grooves 212 are formed on the mounting seat, the two arc-shaped sliding grooves 211 are arranged along the same circumferential track, the two straight sliding grooves 212 are arranged outside the circumferential track and along the radial direction of the circumferential track, and each straight sliding groove 212 is arranged at the midline of an arc-shaped sliding groove 211, a rotating guide rod 310 and a straight guide rod 320 are arranged on each mid-high sound box 300, and when a straight guide rod 320 slides in a straight sliding groove 212, the corresponding rotating guide rod 310 slides in the corresponding arc-shaped sliding groove 211 synchronously to drive the corresponding mid-high sound box 300 to rotate on the mounting seat.

[0049] Specifically, the mounting base includes a mounting plate 210 and a top shell 220. The top shell 220 protrudes from the top of the subwoofer enclosure 100 and has an opening on its side. The mounting plate 210 covers the opening on the side of the top shell 220, and the connection between the top shell 220 and the mounting plate 210 can be selected, but is not limited to, screw connection. Two mid-high frequency speaker enclosures 300 are rotatably connected to the mounting plate 210. The mounting plate 210 has two arc-shaped sliding grooves 211 and two straight sliding grooves 212. The two arc-shaped sliding grooves 211 are located in the same circumferential trajectory, and the two arc-shaped sliding grooves 211 are respectively parts of the upper semicircle in this circumferential trajectory. The rotating guide rod 310 and the straight guide rod 320 are inclinedly arranged on the mid-high frequency speaker enclosures 300. The rotating guide rod 310 is inserted in the arc-shaped sliding groove 211, and the straight guide rod 320 is inserted in the straight sliding groove 212 to connect with the mounting plate 210. Thus, the mid-high frequency speaker enclosures 300 can be rotated by eccentric rotation.

[0050] In the initial state, reference Figure 1 Two mid-high frequency enclosures 300 are vertically arranged side-by-side on top of the woofer enclosure 100. When needed, the mid-high frequency enclosures 300 are lifted diagonally upwards. (See reference...) Figure 2 On the right side of the mid-high frequency speaker enclosure 300, the linear guide rod 320 slides diagonally upward from the bottom end of the straight slide groove 212, while the rotating guide rod 310 simultaneously slides from the bottom end of the arc-shaped slide groove 211 to the top end, until the linear guide rod 320 reaches the top end of the straight slide groove 212. At this point, the rotating guide rod 310 on the mid-high frequency speaker enclosure 300 reaches the center line of the arc-shaped slide groove 211. At this point, the mid-high frequency speaker enclosure 300 moves outward a certain distance, allowing for some rotation. As the mid-high frequency speaker enclosure 300 continues to rotate, the linear guide rod 320 slides diagonally downward from the top end of the straight slide groove 212, while the rotating guide rod 310 simultaneously slides from the center line of the arc-shaped slide groove 211 to the top end, until it rotates completely horizontal. At this point, refer to... Figure 2 The left-side mid-high frequency speaker enclosure 300 is in the unfolded state; when it is necessary to close the mid-high frequency speaker enclosure 300, rotate the mid-high frequency speaker enclosure 300, as shown in the reference. Figure 2 On the left side of the mid-high frequency enclosure 300, the linear guide rod 320 slides diagonally upward from the bottom end of the straight slide groove 212, while the rotating guide rod 310 simultaneously slides downward from the top end of the arc-shaped slide groove 211. This continues until the linear guide rod 320 reaches the top end of the straight slide groove 212, and the rotating guide rod 310 on the mid-high frequency enclosure 300 reaches the center line of the arc-shaped slide groove 211. At this point, the bottom end of the mid-high frequency enclosure 300 can be moved inward to return to its original position. Continuing to rotate the mid-high frequency enclosure 300, the linear guide rod 320 slides diagonally downward from the top end of the straight slide groove 212, while the rotating guide rod 310 simultaneously slides from the center line of the arc-shaped slide groove 211 to the bottom end, until the mid-high frequency enclosure 300 is vertical on the woofer enclosure 100. (Reference) Figure 2The right-side mid-high frequency speaker enclosure 300 is returned to its initial position.

[0051] It is understandable that the two mid-high frequency enclosures 300 and the mounting structure 200 can also be rotatably connected in other ways, which is not limited here, as long as the angle between each mid-high frequency enclosure 300 and the woofer enclosure 100 can be freely adjusted.

[0052] To facilitate the sliding of the rotating guide rod 310 on the mounting base, such as Figures 1 to 4 As shown, in some embodiments, the ends of the rotating guide rod 310 and the linear guide rod 320 away from the mid-high frequency enclosure 300 are provided with limiting members, and the limiting members are locked to the side of the mounting base away from the mid-high frequency enclosure 300.

[0053] Specifically, the limiting component can be, but is not limited to, screws. One end of both the rotating guide rod 310 and the linear guide rod 320 is provided with a limiting hole that mates with the limiting component. The limiting hole is a screw hole. After the rotating guide rod 310 and the linear guide rod 320 are installed on the mounting plate 210, the screws are tightened so that the screws engage with the front surface of the mounting plate 210. In this way, the rotating guide rod 310 and the linear guide rod 320 are fixed on the mounting plate 210, preventing them from detaching from the mounting plate 210.

[0054] To facilitate control of the stationary and moving states of the midrange and tweeter enclosure 300, such as Figures 2 to 5 As shown, in some embodiments, the mounting structure 200 is provided with locking members 400 for locking each mid-high frequency speaker enclosure 300.

[0055] Specifically, the movement of the mid-high frequency speaker enclosure 300 can be controlled by the locking action of the locking element 400.

[0056] To facilitate the use of the locking component 400, such as Figures 2 to 5 As shown, in some embodiments, the locking member 400 is disposed in the mounting base. The locking member 400 includes an inclined guide block 410 and a mating block 420. The mounting base has a pressing hole 221 and an opening 213. The inner side wall of the mounting base is provided with a guide ring 222. An elastic member is disposed in the guide ring 222. One end of the mating block 420 is provided with a sliding part 421. The sliding part 421 slides laterally in the guide ring 222 and abuts against the elastic member, so that the other end of the mating block 420 normally passes through the opening 213 and abuts against each mid-high frequency speaker enclosure 300. The mating block 420 is provided with a guide groove 422. The inclined guide block 410 is provided with a pressing part 411 that passes through the pressing hole 221. When the pressing part 411 is pressed down, the inclined guide block 410 is driven to vertically pass through the guide groove 422 and abut against the side wall of the guide groove 422, so that the sliding part 421 is driven to laterally compress the elastic member to unlock.

[0057] Specifically, referring to Figure 3 and Figure 4 , the mounting plate 210 is provided with an opening 213, the top surface of the top shell 220 is provided with a pressing hole 221, the inner side wall of the top shell 220 is provided with a guide ring 222 in the Y-axis direction, the guide ring 222 is provided with an elastic element in abutment, the elastic element is provided as a spring, the front end of the elastic element is in abutment with the inner side wall of the top shell 220. The front end of the cooperation block 420 is provided with a sliding part 421 protruding horizontally in the Y-axis direction, the sliding part 421 is inserted into the guide ring 222 and is in abutment with the rear end of the elastic element, and the rear end of the cooperation block 420 is provided with an abutment column, and a guide groove 422 is provided on the abutment column, referring to Figure 4 , the abutment column on the cooperation block 420 is in abutment with the medium-high frequency speaker body 300 through the opening 213 under the action of the elastic element, so as to limit the rotation of the medium-high frequency speaker body 300, referring to Figure 5 , the abutment column is provided with a guide groove 422 vertically in the Z-axis direction, the inclined guide block 410 has an inclined guide part, the upper end of the inclined guide part is an inclined surface, and the lower end is a vertically downward extending guide plane, the vertically downward extending guide plane of the inclined guide part slides in the guide groove 422, and when the pressing part 411 is pressed, the inclined surface of the inclined guide part slides into the guide groove 422 and pushes the sliding part 421 to compress the elastic element, thereby driving the cooperation block 420 to gradually move away from the medium-high frequency speaker body 300, and the medium-high frequency speaker body 300 can be unlocked to rotate. It can be understood that the movement direction of the cooperation block 420 and the movement direction of the inclined guide block 410 are perpendicular to each other, the number of inclined guide parts is optional but not limited to two, and when the number of inclined guide parts is two, the number of abutment columns is two to correspond to the two guide grooves 422.

[0058] As shown in Figure 3 , further, the mounting plate 210 is provided with a guide structure 700 for guiding the inclined guide block 410 to pass through the guide groove 422.

[0059] Specifically, the guide structure 700 includes a guide sliding groove and a guide rail, the top end of the inclined guide block 410 is provided with a guide protrusion matched with the guide sliding groove to slide on the guide sliding groove, and the number of guide protrusions is optional but not limited to two. The guide rail cooperates with the bottom end of the inclined guide block 410, that is, cooperates with the vertically downward extending guide plane of the inclined guide part to play a guiding cooperation role, thereby effectively avoiding the deviation of the sliding path and ensuring that the inclined guide block 410 can slide vertically in the Z-axis direction in the guide groove 422.

[0060] It can be understood that the two medium-high frequency speaker bodies 300 and the mounting structure 200 can also be locked by other means, which are not limited herein, as long as each medium-high frequency speaker body 300 can be in a tightly locked state when fixed.

[0061] In order to increase the practicability of the stereo sound box 10, as shown in Figure 1 In some embodiments, the mid-high sound box body 300 and the bass sound box body 100 are respectively provided with a holding structure 500.

[0062] Specifically, by providing the holding structure 500, it is convenient to hold and pull the mid-high sound box body 300 and the mid sound box body. The holding structure 500 can be selected but is not limited to a concave holding part, and only needs to realize the holding and pulling of the sound box. The top end of the mid-high sound box body 300 and the mid sound box body is provided with a holding part, and the cross-sectional shape of the holding part can be selected but is not limited to a square.

[0063] In order to facilitate the placement of the bass sound box body 100, as shown in Figure 1 In some embodiments, the bass sound box body 100 is provided with a positioning and damping structure 600.

[0064] Specifically, by providing the positioning and damping structure 600 on the bottom end of the bass sound box body 100, the displacement of the bass sound box body 100 caused by sound vibration can be prevented, thereby increasing the practicability of the stereo sound box 10. The bass sound box body 100 can be selected but is not limited to a damping foot, and only needs to realize the supporting and damping effect of the bass sound box body 100. The damping foot is made of rubber.

[0065] In order to facilitate the driving of each mid-high sound box body 300 to rotate, in some embodiments, the stereo sound box 10 further comprises a driver for driving each mid-high sound box body 300 to rotate on the bass sound box body 100, and the output end of the driver is connected with each mid-high sound box body 300.

[0066] Specifically, the driver can be installed in the mounting structure, that is, the driver can be installed in the top shell 220. The mounting plate 210 is provided with a hole, and the output end of the driver passes through the mounting plate 210 and is connected with each mid-high sound box body 300. The driver can be selected but is not limited to a motor. By driving each mid-high sound box body 300 through the motor, the rotation angle of the mid-high sound box body 300 can be accurately controlled to control the folding or unfolding of the two mid-high sound box bodies 300 on the bass sound box body 100. The way in which the motor drives each mid-high sound box body 300 to rotate on the bass sound box body 100 is known to those skilled in the art and can be realized, and is not described in detail in this embodiment.

[0067] Further, the driver can be provided as a plurality of motors, and the output end of each motor is connected with a mid-high sound box body 300 to drive the mid-high sound box body 300 respectively. The driver can drive each mid-high sound box body 300 to rotate synchronously, or can drive the corresponding mid-high sound box body to rotate individually. For example, the driver can synchronously drive two mid-high sound box bodies 300 to rotate in opposite directions.

[0077] In this way, the specific rotation structure of the application is:

[0078] ​​The mounting structure 200 is located at the top rear side of the woofer enclosure 100. The height of the mounting structure 200 is adapted to the overall length of the mid-high frequency enclosure 300, so that the mid-high frequency enclosure 300 can rotate around an axis on the front side of the mounting structure 200. Two arc-shaped grooves 211 and two straight grooves 212 are formed on the top front side of the mounting plate 210. The two arc-shaped grooves 211 are portions of the lower semicircle of this circular trajectory, and the two straight grooves 212 are located below and outside the two arc-shaped grooves 211. A rotating guide rod 310 and a straight guide rod 320 are connected to the rear surface of the mid-high frequency enclosure 300. The rotating guide rod 310 is inserted into the arc-shaped groove 211, and the straight guide rod 320 is inserted into the straight groove 212 to connect with the mounting plate 210. This allows the two mid-high frequency enclosures 300 to rotate on the woofer enclosure 100 through eccentric rotation.

[0079] In the initial state, reference Figure 6 and Figure 7 Two mid-high frequency speaker enclosures 300 are vertically arranged side-by-side on top of the bass speaker enclosure 100. When needed, the mid-high frequency speaker enclosures 300 are lifted. (Refer to...) Figure 7 The linear guide rod 320 slides diagonally downwards from the top of the straight groove 212, while the rotating guide rod 310 simultaneously slides from the top to the bottom of the arc-shaped groove 211 until the linear guide rod 320 reaches the bottom of the straight groove 212. The rotating guide rod 310 on the midrange / high-frequency enclosure 300 then reaches the center line of the arc-shaped groove 211. Continuing to rotate the midrange / high-frequency enclosure 300, the linear guide rod 320 slides diagonally upwards from the bottom of the straight groove 212, while the rotating guide rod 310 simultaneously slides from the center line of the arc-shaped groove 211 to the bottom. (Reference) Figure 8 The rotation continues until the linear guide rod 320 is at the top of the straight slide groove 212 and the rotating guide rod 310 is at the bottom of the arc-shaped slide groove 211. At this point, the mid-high frequency speaker enclosure 300 is in the unfolded state.

[0080] It is also understood that in this embodiment, there is no need for clearance between the adjacent sides of the two mid-high frequency enclosures 300, and the eccentric shaft can move its relative position to avoid interference when rotating the mid-high frequency enclosure 300.

[0081] However, in this embodiment, a clearance gap is provided between the bass enclosure 100 and the mid-high frequency enclosure 300.

[0082] Specifically, an avoiding gap can be arranged between the bottom end of the mid-high speaker cabinet 300 and the top end of the bass speaker cabinet 100, so that the top end of the bass speaker cabinet 100 can not interfere with the rotation of the mid-high speaker cabinet 300, i.e. the mid-high speaker cabinet 300 can be freely rotated on the mounting structure 200, so as to have a rotation space during the rotation of the mid-high speaker cabinet 300. It can be understood that the avoiding gap between the bass speaker cabinet 100 and the mid-high speaker cabinet 300 is subject to actual production requirements, which is not limited herein, and only needs to ensure that the mid-high speaker cabinet 300 can be freely rotated on the bass speaker cabinet 100.

[0083] In addition, in the present embodiment, the locking member 400 is not required, and the connection between the sliding groove and the guide rod can be a relatively tight connection, so as to be relatively stationary with the bass speaker cabinet 100 when the mid-high speaker cabinet 300 reaches the corresponding position. That is, the mounting structure 200 and the mid-high speaker cabinet 300 can be stably stationary by the action of friction without external force. In this way, the bass speaker cabinet 100, the mounting structure 200 and the mid-high speaker cabinet 300 are relatively stationary in normal state; and the mid-high speaker cabinet 300 can be rotated on the mounting structure 200 when subjected to a certain pushing force.

[0084] In addition, in the present embodiment, the arc-shaped sliding groove 211 and the straight sliding groove 212 are provided with shockproof members 214.

[0085] Specifically, the shockproof members 214 are arranged at one end of the arc-shaped sliding groove 211 and the straight sliding groove 212 close to the mid-high speaker cabinet 300, i.e. the front end of the arc-shaped sliding groove 211 and the straight sliding groove 212; and the front end surface of the shockproof member 214 is flush with the front side surface of the mounting plate 210. The shockproof member 214 can be but is not limited to a silica gel sleeve, which is sleeved on the corresponding sliding groove periphery. Since the rear end of the straight guide rod 320 and the rear end of the rotating guide rod 310 are both connected with screws for clamping and limiting, the silica gel sleeve can be clamped by the rear end surface of the silica gel sleeve on the corresponding sliding groove through the screws, so as to avoid the straight guide rod 320 and the rotating guide rod 310 from being separated from the corresponding sliding groove, and thus the mid-high speaker cabinet 300 can be locked on the mounting structure 200. In this way, the shockproof member 214 can achieve the purposes of shockproof and anti-loosening. In addition, the position of the mid-high speaker cabinet 300 on the mounting structure 200 can be limited and fixed to a certain extent, so that the guide rod cannot be separated from the corresponding sliding groove and can be rotated with a little force.

[0086] Embodiment 5

[0087] The present embodiment is similar to Embodiment 4, and the difference lies in that, as shown in Figure 9 The structure for cooperating and connecting between the mounting structure 200 and the mid-high speaker cabinet 300 is arranged as a center shaft structure, and the specific structure is as follows:

[0088] The mounting plate 210 of the mounting structure 200 is provided with a central shaft 215, the mid-high speaker body 300 is connected with a rotating shaft 330, and the rotating shaft 330 is sleeved on the central shaft 215 and is in rotating connection with the outer side surface of the central shaft 215, so as to drive the mid-high speaker body 300 to rotate on the mounting structure 200.

[0089] Specifically, two central shafts 215 are arranged on the front top end of the mounting plate 210, the mid-high speaker body 300 is provided with an accommodating groove matched with the rotating shaft 330, the rotating shaft 330 is arranged 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 central shaft 215, so that the mid-high speaker body 300 can be driven to rotate by rotating the rotating shaft 330 around the central shaft 215.

[0090] In this embodiment, the locking piece 400 is provided.

[0091] Specifically, 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 matched. The locking piece 400 is selected but not limited to a bolt, which passes through the through hole from the rear 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. The pin hole can be arranged at a corresponding position, so that the mid-high speaker body 300 can be fixed when the angle between the mid-high speaker body 300 and the bass speaker body 100 is 90° or 180°. The specific arrangement of the pin hole is subject to actual production requirements and is not limited herein.

[0092] In addition, in this embodiment, the limiting piece is arranged according to the specific production situation, as long as the rotation between the mid-high speaker body 300 and the mounting structure 200 can be avoided while the mid-high speaker body 300 is separated 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 being separated 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 central shaft 215, so as to buffer the mid-high speaker body 300.

[0093] In this way, the mid-high speaker body 300 can be rotated by 90° to 180° through the cooperation and rotation of the central shaft 215 and the rotating shaft 330, and the mid-high speaker body 300 is fixed in the required direction through the bolt.

[0094] Embodiment 6

[0095] This embodiment is a further embodiment of embodiment 5, and in this embodiment, the structure matched and connected between the mounting structure 200 and the mid-high speaker body 300 is a spring central shaft structure.

[0096] Specifically, compared with the center shaft structure, the spring center shaft structure adds a spring fixing shaft on the mounting plate 210 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, and in the folded state, the tension of the spring tightly abuts the bottom end face of the mid-high pitch 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 bottom end of the mid-high pitch box body 300 and the top end of the bass box body 100 in the folded state can be gapless, thereby effectively reducing the occupied space and facilitating storage.

[0097] 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 bass box body 100 under the action of the magnetic force, and when an external force pulls open the mid-high pitch box body 300, the mid-high pitch box body 300 can rotate on the bass box body 100.

[0098] In embodiments 7 to 9, and in the accompanying Figure 10 to the accompanying Figure 13 In this embodiment, the coordinate system is referred to Figure 10 , 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.

[0099] Embodiment 7

[0101] The specific rotating structure of the present application is:

[0102] The overall length of the midrange / high-frequency enclosure 300 is adapted to the length of the bass enclosure 100, allowing the midrange / high-frequency enclosure 300 to unfold or close on the left and right sides of the bass enclosure 100. The mounting structure 200 includes two mounting bases, which can be plate-like. The two mounting bases are located on opposite sides of the bass enclosure 100. The rear sides of the two mounting bases have an arc-shaped groove 211 and a straight groove 212. The midrange / high-frequency enclosure 300 has a concave mating groove. A rotating guide rod 310 and a straight guide rod 320 protrude forward from the rear side wall of the concave mating groove. When the mounting base is inserted into the corresponding concave mating groove, the rotating guide rod 310 is inserted into the arc-shaped groove 211, and the straight guide rod 320 is inserted into the straight groove 212. This allows the two midrange / high-frequency enclosures 300 to rotate eccentrically. Thus, the midrange / high-frequency enclosure 300 and the bass enclosure 100 can form an L-shaped structure through the mounting structure 200.

[0103] In the initial state, reference Figure 10 and Figure 11 Two mid-high frequency speaker enclosures 300 are vertically arranged side-by-side on the left and right sides of the bass speaker enclosure 100. When needed, the mid-high frequency speaker enclosures 300 are lifted. (Refer to...) Figure 11 The linear guide rod 320 slides diagonally downwards from the top of the straight groove 212, while the rotating guide rod 310 simultaneously slides from the top to the bottom of the arc-shaped groove 211 until the linear guide rod 320 reaches the bottom of the straight groove 212. The rotating guide rod 310 on the midrange / high-frequency enclosure 300 then reaches the center line of the arc-shaped groove 211. Continuing to rotate the midrange / high-frequency enclosure 300, the linear guide rod 320 slides diagonally upwards from the bottom of the straight groove 212, while the rotating guide rod 310 simultaneously slides from the center line of the arc-shaped groove 211 to the bottom. (Reference) Figure 12 The rotation continues until the linear guide rod 320 is at the top of the straight slide groove 212 and the rotating guide rod 310 is at the bottom of the arc-shaped slide groove 211. At this point, the mid-high frequency speaker enclosure 300 is in the unfolded state.

[0104] It is also understood that in this embodiment, when the mid-high frequency enclosure 300 and the bass enclosure 100 are at the same height and the top of the mid-high frequency enclosure 300 is connected to the mounting structure 200, there is no need to set an additional clearance between the mid-high frequency enclosure 300 and the bass enclosure 100. When the mid-high frequency enclosure 300 is rotated, the eccentric shaft can move to a different position to avoid interference.

[0105] In this embodiment, the arc-shaped slide 211 and the straight slide 212 can be arranged through the front and rear sides of the mounting base, and both ends of the arc-shaped slide 211 and the straight slide 212 are connected with silicone sleeves to prevent the screws from coming out.

[0106] In addition, in this embodiment, a baffle is provided on the front surface of the subwoofer enclosure 100 to block the rotating structure of the speaker and increase the overall aesthetics of the speaker.

[0109] Specifically, the rear side wall of the concave matching groove of the mid-high speaker box 300 is provided with a center shaft 215 protruding forward, and the rear side of the mounting seat of the mounting structure 200 is provided with a containing groove matched with the rotating shaft 330 to contain the rotating shaft 330. The rotating shaft 330 is installed in the containing 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 speaker box 300 can be driven to rotate by rotating the rotating shaft 330 around the center shaft 215.

[0110] In this embodiment, there is a locking piece 400.

[0111] Specifically, a through hole is formed on the mid-high speaker box 300 along the Y-axis direction, and a plurality of pin holes are formed on the mounting seat of the mounting structure 200 in cooperation. The locking piece 400 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 box 300 on the mounting structure 200. Among them, the pin hole can be arranged at the corresponding position, so that the mid-high speaker box 300 can be fixed when forming a 90° angle and a 180° angle with the bass speaker box 100. And the specific arrangement of the pin hole is subject to the actual production demand, which is not limited here.

[0112] In addition, in this embodiment, the limiting piece is set according to the specific production situation, as long as it can rotate between the mid-high speaker box 300 and the mounting structure 200 while avoiding the mid-high speaker box 300 from separating from the mounting structure 200, such as a detent structure can be arranged between the center shaft 215 and the rotating ring to avoid the mid-high speaker box 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 center shaft 215 to buffer the mid-high speaker box 300.

[0113]
