[0040] Figures 1 to 6 The hanging mechanism 10 in some embodiments of the utility model is shown. The hanging mechanism 10 is used to be set on the shell 30. The hanging mechanism 10 can hang the shell 30 in a predetermined position. It should be noted that the hanging mechanism 10 can not only be applied to the field of audio, but also can be used to hang products in other fields that need to be hung. The hanging mechanism 10 can also be used to hang products in other fields, and the deformation of the shell of products in other fields caused by the hanging force can also be avoided.

[0041] like Figures 3 to 5 As shown, the hoisting mechanism 10 includes a hoisting assembly 1 and a reinforcement assembly 2. The hoisting assembly 1 is used to connect the external hoisting structure, for example, it can be used to connect with the external hoisting hook, lifting lug, lifting belt and other lifting structures, which varies depending on the actual hoisting design and application scenario. The reinforcement assembly 2 is used to transmit the hoisting force in the hoisting assembly 1. Of course, the reinforcement assembly 2 also plays a certain structural reinforcement role.

[0042] like Figures 3 to 5 As shown, the hanging assembly 1 includes a first hanging seat 11 , at least one first hanging connection piece 12 , a second hanging seat 13 and at least one second hanging connection piece 14 , and the first hanging seat 11 and the second hanging seat 13 are symmetrically arranged on the housing 30 .

[0043] It can be understood that the first suspension seat 11 and the second suspension seat 13 together play a role in connecting with the reinforcement assembly 2. The first suspension connector 12 is used to install and fix the first suspension seat 11 to the housing 30. The second suspension connector 14 is used to install and fix the second suspension seat 13 to the housing 30.

[0044] like Figures 3 to 6 As shown, the reinforcement assembly 2 includes at least one reinforcement member 21, and the first lifting connector 12 and the second lifting connector 14 are respectively connected to the reinforcement member 21. The first lifting connector 12 holds the first hanging seat 11 on the shell 30, and the second lifting connector 14 holds the second hanging seat 13 on the shell 30.

[0045] It can be understood that the reinforcement member 21 is not stretchable as a whole, which prevents the reinforcement member 21 from being accidentally deformed due to the force during the hoisting process, thereby ensuring the structural stability of the housing 30. The number of reinforcement members 21 can be set to one or more, depending on the weight of the product to be hoisted, to ensure that the reinforcement member 21 can support the product of the corresponding weight and ensure the corresponding structural stability during hoisting.

[0046] It should be noted that the first lifting connector 12 and the second lifting connector 14 can be configured as various components or structures in the prior art that can play a role in installation and connection. The connection method between the first lifting connector 12 and the reinforcement 21 and the connection method between the second lifting connector 14 and the reinforcement 21 can be configured as screw connection, clamping, welding, bonding or interference connection.

[0047] It should also be noted that the first lifting connector 12 can be configured to correspond to any position connected to the reinforcement 21, as long as the first lifting connector 12 and the reinforcement 21 can be kept fixed after the connection. Similarly, the connection position of the second lifting connector 14 on the reinforcement 21 can also be flexibly set. In this way, once the first lifting connector 12 and the second lifting connector 14 are connected to the reinforcement 21, the relative positions of the first lifting connector 12 and the second lifting connector 14 are fixed.

[0048] like Figure 4 and Figure 6 As shown, at least one hoisting position 15 for hoisting is provided on the first hoisting seat 11 and / or the second hoisting seat 13 .

[0049] It should be noted that the symmetrical arrangement of the first hanger 11 and the second hanger 13 means that the first hanger 11 and the second hanger 13 are respectively arranged on two opposite surfaces of the shell 30, so that no matter whether the hoisting connection position is the first hanger 11 or the second hanger 13, the hoisting force can be correspondingly transmitted from one surface of the shell 30 to the other opposite surface through the reinforcement 21. Of course, it should also be noted that since the first hanger 11 and the second hanger 13 are connected by the reinforcement 21, the surface of the shell 30 where the first hanger 11 is arranged and the surface where the second hanger 13 is arranged are fixed, that is, the relative positions of the two opposite surfaces on the shell 30 are fixed, therefore, the overall structure of the shell 30 will also be fixed, avoiding bending deformation of the shell 30 under force, and ensuring the structural stability of the shell 30.

[0050] It should be noted that the lifting position 15 is used to adapt and connect with the external lifting structure; according to different product designs, differences in application scenarios and differences in application solutions, the lifting position 15 can be set only on the first hanging seat 11, or only on the second hanging seat 13, or on both the first hanging seat 11 and the second hanging seat 13.

[0051] like Figures 3 to 6 As shown, in some embodiments of the hoisting mechanism 10, the hoisting assembly 1 includes a plurality of first hoisting connectors 12 and a plurality of second hoisting connectors 14, and the reinforcement assembly 2 includes a plurality of reinforcement members 21;

[0052] Each first lifting connector 12 is connected to each reinforcement member 21 one by one, each second lifting connector 14 is connected to the reinforcement member 21 one by one, the first hanging seat 11 is supported by each first lifting connector 12 and abuts against the shell 30, and the second hanging seat 13 is supported by each second lifting connector 14 and abuts against the shell 30.

[0053] It can be understood that the arrangement of the plurality of first hanging connectors 12 and the plurality of second hanging connectors 14 improves the stability of the first hanging seat 11 on the housing 30, preventing the first hanging seat 11 from being loosened from the housing 30. Similarly, the arrangement stability of the second hanging seat 13 on the housing 30 is also improved to a certain extent. The arrangement of the plurality of reinforcement members 21 can further improve the structural stability of the housing 30.

[0054] It should be noted that each reinforcement member 21 is individually connected to a first lifting connector 12 and a second lifting connector 14. Therefore, each reinforcement member 21 can individually play a role in reinforcing the connection, and then multiple positions of the first hanging seat 11 and the second hanging seat 13 can strengthen the connection of the member 21, further improving the structural stability of the shell 30.

[0055] like Figures 4 to 6 As shown, in some embodiments of the lifting mechanism 10, the lifting assembly 1 includes four first lifting connectors 12 and four second lifting connectors 14, and the reinforcement assembly 2 includes four reinforcement members 21;

[0056] The first hanging seat 11 includes a first hanging plate 112 and a first hanging ridge 113. The first hanging ridge 113 is arranged on the first hanging plate 112. Four first hanging connecting members 12 are all passed through the first hanging plate 112 and the housing. The four first hanging connecting members 12 are symmetrically arranged on the left and right sides of the first hanging ridge 113.

[0057] The second hanging seat 13 includes a second hanging plate 132 and a second hanging ridge 133. The second hanging ridge 133 is arranged on the second hanging plate 132. Four second hanging connectors 14 are all passed through the second hanging plate 132 and the housing. The four second hanging connectors 14 are symmetrically arranged on the left and right sides of the second hanging ridge 133.

[0058] Among them, the four first lifting connectors 12 are screwed to one end of the reinforcement 21 one by one, and the four second lifting connectors 14 are screwed to the other end of the reinforcement 21 one by one. At least one lifting position 15 is set on the first hanging spine 113 and / or the second hanging spine 133.

[0059] It can be understood that in this embodiment, by providing four reinforcement members 21, the first suspension bracket 11 and the second suspension bracket 13 are reinforced and connected from four different positions, so that a stable and reliable connection reinforcement can be formed at the four positions.

[0060] The first lifting connector 12 and the second lifting connector 14 can be configured as common threaded connectors in the prior art such as bolts and screws. The threaded fit has the advantage of tight and firm fit. In addition, the progressive fit of the threaded connection also allows the first lifting connector 12 to be gradually threaded and tightened to form a gradually strengthened support for the first hanging seat 11. Similarly, the second hanging seat 13 can also be gradually pressed and fixed on the shell 30, thereby further improving the structural stability of the shell 30.

[0061] It should be noted that the first hanging plate 112 and the shell 30 are in surface-to-surface contact, and the first hanging ridge 113 is used to connect with an external hanging structure. The second hanging plate 132 and the shell 30 are in surface-to-surface contact, and the second hanging ridge 133 is used to connect with an external hanging structure. Preferably, the first hanging ridge 113 is preferably configured to be set at the center of the first hanging plate 112, and the second hanging ridge 133 is configured to be set at the center of the second hanging plate 132, so that when it is directly hoisted and connected to the first hanging ridge 113, the hoisting force can be evenly transmitted to the first hanging plate 112, and further evenly transmitted to the reinforcement component 2. Similarly, when it is directly hoisted and connected to the second hanging ridge 133, the hoisting force will also be evenly transmitted to various positions of the second hanging plate 132.

[0062] It should also be noted that, since both the first hanging plate 112 and the second hanging plate 132 are in the shape of plates, they can contact the shell 30 with as large a contact area as possible, thereby avoiding the problem of damage caused by stress concentration due to a small contact area.

[0063] Furthermore, in some embodiments, if the first hanging plate 112 is disposed at a position with a low flatness on the housing 30, the first hanging plate 112 may be configured to ensure tightness of fit between the first hanging plate 112 and the housing 30. Of course, the second hanging plate 132 may also be configured to improve the fit between the second hanging plate 132 and the housing 30.

[0064] like Figures 4 to 6 As shown, in some embodiments of the lifting mechanism 10, the reinforcement 21 includes a reinforcement rod, the first lifting connector 12 passes through the first hanger 11 and is screwed to one end of the reinforcement rod, and the second lifting connector 14 passes through the second hanger 13 and is screwed to the other end of the reinforcement rod.

[0065] It can be understood that the reinforcing rod is rod-shaped as a whole, and the cross-section of the reinforcing rod can be configured as a circle, an ellipse, a triangle, a rectangle or other shapes as long as a reliable connection support can be formed.

[0066] It should be noted that the first lifting connector 12 and the second lifting connector 14 are screwed to the end of the reinforcing rod, and the end may refer to the end face of the end position of the reinforcing rod, or may refer to other positions adjacent to the end face on the reinforcing rod, for example, may refer to the position adjacent to the end face on the peripheral side of the reinforcing rod.

[0067] like Figure 6 As shown, in some embodiments of the lifting mechanism 10 , the length extension direction D1 of each reinforcement member 21 coincides with the length extension direction D2 of the first lifting connector located at the end.

[0068] It can be understood that D1 and D2 overlap with each other, which will enable the lifting force to be transmitted between the first lifting connector and the reinforcement 21 along the same straight line, avoiding the lifting force from being concentrated on the connection position between the first lifting connector and the reinforcement 21, and preventing the connection position between the two from being damaged or broken due to excessive force.

[0069] like Figure 6 As shown, the length extension direction D1 of each reinforcement member 21 coincides with the length extension direction D3 of the second hanging connection member located at the end.

[0070] It can be understood that according to the description that D1 and D2 overlap each other in the above embodiment, the lifting force can be transmitted along the same straight line between the reinforcement member 21 and the second lifting connector. Therefore, the lifting force can be transmitted along a straight line between the first hanging seat 11 and the second hanging seat 13 through the first hanging connector 12, the reinforcement member 21 and the second hanging connector 14, providing stable and reliable support.

[0071] like Figures 3 to 5 As shown, in some embodiments of the lifting mechanism 10, the lifting assembly 1 also includes a first lifting block 151, a first locking bolt 152 and a first locking nut 153, at least one connecting hole is opened on the first lifting block 151, the first locking bolt 152 passes through the first lifting block 151 and the lifting position 15, and the first locking nut 153 is screwed onto the first locking bolt 152.

[0072] It can be understood that the connection hole on the first hanging block 151 is used for hanging connection. The first locking bolt 152 is used to fix the first hanging block 151 to the first hanging seat 11. Of course, the fixing method can be a fixed connection, that is, the first hanging block 151 cannot rotate on the first hanging seat 11; the fixing method can also be a movable connection, that is, the first hanging block 151 can rotate to a certain extent on the first hanging seat 11, so that the first hanging block 151 can be hung in different directions. The setting of the first locking nut 153 can prevent the first locking bolt 152 from coming off the first hanging seat 11.

[0073] like Figure 4 As shown, in some embodiments of the hoisting mechanism 10, the hoisting assembly 1 further includes a plurality of first angle irons 161, a plurality of first angle connectors 162, a plurality of second angle irons 163 and a plurality of second angle connectors 164, and each of the first angle irons 161 and each of the second angle irons 163 are disposed on the housing 30;

[0074] Among them, each first corner connector 162 is penetrated by the first hanging seat 11, and the first corner connector 162 is screwed to each first angle iron 161 one by one, and each second corner connector 164 is penetrated by the second hanging seat 13, and each second corner connector 164 is screwed to each second angle iron 163 one by one.

[0075] It can be understood that the first angle iron 161 is used to connect the first suspension seat 11 and the shell 30 to fix the position of the first suspension seat 11 on the shell 30, so as to avoid the position fixation of the first suspension seat 11 being completely dependent on the connection with the reinforcement component 2, and to prevent the first suspension seat 11 from accidentally sliding on the shell 30. The connection between the first angle iron 161 and the shell 30 can be connected by screws, bolts or other threaded connectors, and can also be connected by welding, clamping, bonding or interference connection. Similarly, the function of the second angle iron 163 is similar to that of the first angle connector 162, and the second suspension seat 13 is fixed on the shell 30 due to the second hanging connector 14.

[0076] It should be noted that the first corner connector 162 and the second corner connector 164 can both be configured as bolts, screws or other threaded connection structures in the prior art.

[0077] like Figure 2 As shown, in some embodiments of the lifting mechanism 10, the lifting mechanism 10 further includes an auxiliary lifting component 3. Figures 2 to 4 As shown, the auxiliary hanging component 3 is used to hang together with the hanging component 1 from different positions on the shell 30.

[0078] The auxiliary hanging assembly 3 includes an auxiliary hanging plate 31, an auxiliary hanging connector 32 and at least one auxiliary hanging ear 33. The auxiliary hanging plate 31 is arranged on the shell 30. The auxiliary hanging connector 32 passes through the auxiliary hanging plate 31 and is connected to the shell 30. Each auxiliary hanging ear 33 is arranged on the auxiliary hanging plate 31, and each auxiliary hanging ear 33 is used for hanging and connecting; wherein, the length extension direction D4 of the auxiliary hanging plate 31 is parallel to the length extension direction D1 of the reinforcement 21.

[0079] It can be understood that the auxiliary hanging plate 31 can be configured to be connected to the housing 30 at multiple positions, that is, the number of auxiliary hanging connectors 32 is configured to be multiple, and multiple auxiliary hanging connectors 32 correspondingly fix the auxiliary hanging plate 31 to the housing 30 from multiple different positions. The auxiliary hanging ears 33 are used to connect with the external hanging structure, so as to further hang and connect the housing 30 through the auxiliary hanging plate 31 and the auxiliary hanging connectors 32.

[0080] It should be noted that D4 is parallel to D1 , so that the auxiliary suspension plate 31 can be supported and connected to the reinforcement member 21 from different positions on the shell 30 in parallel directions, further improving the structural stability of the shell 30 .

[0081] like Figure 3 As shown, in some embodiments of the lifting mechanism 10 , the lifting mechanism 10 includes two auxiliary lifting components 3 , two auxiliary lifting plates 31 are both arranged on the outer shell, and the length extension direction D4 of each auxiliary lifting plate 31 is parallel to the length extension direction D1 of the reinforcement 21 .

[0082] It can be understood that the provision of the two auxiliary hanging components 3 enables the housing 30 to be hung and fixed from three different positions through the two auxiliary hanging components 3 and the hanging component 1, thereby improving the hanging stability of the product.

[0083] The utility model also provides a speaker 20, which includes a shell 30 and a lifting mechanism 10; wherein, a plurality of limit grooves 50 are respectively arranged on two opposite inner wall surfaces in the shell 30, and each end of each reinforcement member 21 is correspondingly arranged in each limit groove 50.

[0084] It can be understood that the end of each reinforcement member 21 will be correspondingly limited in a limiting groove 50, so that the position of each reinforcement member 21 in the shell 30 will be limited. The position of the reinforcement member 21 is limited, which also means that the relative position of the first hanging seat 11 and the second hanging seat 13 connecting the reinforcement member 21 is limited, and further enables the first hanging seat 11 and the second hanging seat 13 to provide stable and reliable support and fixation to the shell 30.

[0085] like Figures 3 to 6 As shown, the two opposite outer surfaces of the shell 30 are respectively recessed inward, thereby forming two avoidance grooves 60 on the outer surface of the shell 30, and two connecting bosses 70 are formed in the shell 30, the first hanger 11 is arranged in one of the avoidance grooves 60, the second hanger 13 is arranged in the other avoidance groove 60, one end of the reinforcement 21 is supported on one of the connecting bosses 70, and the other end of the reinforcement 21 is supported on the other connecting boss 70; the speaker 20 also includes two I-shaped frames 40, each I-shaped frame 40 is connected to the inner wall surface of the shell 30, each I-shaped frame 40 is respectively connected to the two connecting bosses 70, and the reinforcement 21 is located between the two I-shaped frames 40.

[0086] It can be understood that the two avoidance grooves 60 are used to respectively accommodate the first hanger 11 and the second hanger 13, which can reduce or eliminate the protrusions formed by the first hanger 11 and the second hanger 13 on the outer surface of the shell 30. The connecting boss 70 is used for corresponding connection of the reinforcement member 21. The setting of the I-shaped frame 40 enables the two connecting bosses 70, the connecting boss 70 and other inner wall surfaces of the shell 30, and other inner wall surfaces of the shell 30 to be reinforced and connected, ensuring that the shape of each inner wall surface remains stable, further improving the structural stability of the product.

[0087] The implementation of the hoisting mechanism and the sound system of the utility model has at least the following beneficial effects:

[0088] The hoisting mechanism and the speaker of the utility model relate to the field of speakers. By setting the hoisting components and the reinforcing components, the force distribution during the hoisting process is made more uniform, which greatly enhances the structural stability of the shell, thereby avoiding the occurrence of deformation. Secondly, since the deformation problem is effectively solved, the deformation of the shell is prevented from interfering with the acoustic structure inside the speaker, thereby preventing the distortion or weakening of the sound output, ensuring the stability of the speaker during the hoisting process, and further ensuring the clarity and fidelity of the sound output.
