Description

Technical Field

[0001] The present application relates to the technical field of speaker equipment, and specifically to a cloth-wrapped bracket deformation structure and a speaker. Background Art

[0002] A fabric speaker is a speaker with fabric as the exterior material. In the related art, a fabric speaker includes a speaker assembly, a cloth-wrapped bracket and fabric, wherein the cloth-wrapped bracket is wrapped around the speaker assembly, and the fabric is fixedly connected to the cloth-wrapped bracket.

[0003] However, when assembling the speaker box in the related art, the cloth wrapping bracket needs to be stretched out to place the speaker assembly. Although the strength of the cloth wrapping bracket is reduced through the punching process at the turning point of the current cloth wrapping bracket, the holes opened are circular holes or regular hexagonal holes, so that the strength of the cloth wrapping bracket is still relatively high, which is not conducive to the smooth deformation of the cloth wrapping bracket when it is stretched out, causing the cloth wrapping bracket to crack at the turning point. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present application provides a cloth-wrapped bracket deformation structure and a speaker, which solves the problem of the cloth-wrapped bracket cracking at the turning point when being stretched out during assembly of the speaker.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a cloth wrapping bracket deformation structure, including a cloth wrapping bracket, characterized in that one end of the cloth wrapping bracket in a first direction extends and bends to form at least one turning structure, at least one of the turning structures is provided with a first structural hole, the first structural hole has a first axis and a second axis, the direction of the first axis is the same as the first direction, the direction of the second axis is different from the direction of the first axis, and the length of the first axis is greater than the length of the second axis.

[0006] Preferably, the direction of the second axis is the same as the second direction, and the second direction is perpendicular to the first direction.

[0007] Preferably, the first structural hole is any one of an elliptical hole, a long hexagonal hole, a diamond hole, or a composite hole formed by a combination of several basic holes, or an irregular hole with an irregular contour.

[0008] Preferably, the cloth wrapping bracket is provided with a bending groove, and the bending groove is provided on an inner turning surface of the turning structure.

[0009] Preferably, the cloth wrapping bracket is formed with a plurality of turning structures, and a plurality of bending grooves are provided between any two adjacent turning structures, and the plurality of bending grooves are provided at intervals along the first direction.

[0010] Preferably, the opening direction of the bending groove is the same as the second direction.

[0011] Preferably, the length of the bending groove is S, the length of the cloth wrapping bracket in the second direction is L, and 0.4≤S / L≤0.75.

[0012] Preferably, it also includes a sound plate, which is fixedly connected to the cloth wrapping bracket, and the sound plate is located on one side of the turning structure. A second structural hole is opened on the sound plate, and the second structural hole has a third axis. The direction of the third axis is the same as the first direction, and the length of the third axis is less than the length of the first axis.

[0013] A sound box comprises the above-mentioned cloth-wrapped bracket and a speaker assembly, wherein the speaker assembly comprises a diaphragm, and a portion of the diaphragm fold close to the turning structure faces the opening of the bending groove.

[0014] A sound box comprises the above-mentioned cloth-wrapped bracket.

[0015] The present application provides a cloth-wrapped bracket deformation structure and a speaker, which have the following beneficial effects:

[0016] The cloth wrap bracket deformation structure is achieved by opening a structural hole on the turning structure, and making the direction of the first axis of the structural hole the same as the first direction of the cloth wrap bracket, and the length of the first axis is greater than the length of the second axis. Since the turning structure is formed by extending and bending one end of the cloth wrap bracket, the structural strength of the cloth wrap bracket is weakened, and the structural strength of the cloth wrap bracket is lost most in the first axis direction, so that the cloth wrap bracket can undergo elastic deformation when it is stretched, thereby solving the problem of the cloth wrap bracket cracking at the turning point when it is stretched during speaker assembly.

[0029] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] The technical solution of the present application is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] Embodiment 1:

[0033] See also Figure 1The present application provides a technical solution: a deformation structure of a cloth-wrapped bracket 1, comprising a cloth-wrapped bracket 1, one end of the cloth-wrapped bracket 1 in a first direction is extended and bent to enclose a containing space 3, and at least one turning structure 2 is formed on the cloth-wrapped bracket 1. In the present embodiment, two turning structures 2 are formed on the cloth-wrapped bracket 1, and a plurality of first structure holes 4 are provided on the two turning structures 2, and the plurality of first structure holes 4 are sequentially spaced apart along the second direction of the cloth-wrapped bracket 1. An array of sound-transmitting holes 5 is provided between two adjacent turning structures 2, and the array of sound-transmitting holes 5 includes a plurality of rows of sound-transmitting holes 5 sequentially staggered along the first direction of the cloth-wrapped bracket 1, and each row of sound-transmitting holes 5 is sequentially spaced apart along the second direction of the cloth-wrapped bracket 1. In the present embodiment, the cloth-wrapped bracket 1 is arranged in a rectangular sheet shape, the first direction is the length direction of the cloth-wrapped bracket 1, and the second direction is the width direction of the cloth-wrapped bracket 1. In other embodiments of the present application, the cloth-wrapped bracket 1 is arranged in a square sheet shape, the first direction is the direction of the length of one side of the cloth-wrapped bracket 1, the second direction is the direction of the length of another side of the cloth-wrapped bracket 1, and the second direction is perpendicular to the first direction.

[0034] See also Figure 1 and Figure 2 , each first structural hole 4 is the same, the first structural hole 4 includes a first axis and a second axis, the direction of the first axis is the same as the length direction of the cloth wrapping bracket 1, the direction of the second axis is the same as the width direction of the cloth wrapping bracket 1, and the length of the first axis is greater than the length of the second axis. In this embodiment, the first structural hole 4 is a long hexagonal hole, which is a hexagonal hole whose circumscribed circle is an ellipse. In other embodiments of the present application, the first structural hole 4 can also be any one of an elliptical hole, a diamond hole or a rectangular hole.

[0035] See also Figure 3 , the cloth wrapping bracket 1 is provided with a bending groove 6, and the bending groove 6 is provided on the inner turning surface of the turning structure 2, which is conducive to the deformation of the cloth wrapping bracket 1. The opening direction of the bending groove 6 is the same as the width direction of the cloth wrapping bracket 1. The length of the bending groove 6 is S, and the width of the cloth wrapping bracket 1 is L, 0.4≤S / L≤0.75. When S / L<0.4, the length of the bending groove 6 is too short, so that the cloth wrapping bracket 1 is still difficult to deform; when S / L>0.4, the length of the bending groove 6 is too short, which makes the cloth wrapping bracket 1 easy to break at the bending groove 6 when it is stretched, and the structural strength of the cloth wrapping bracket 1 is greatly lost. When 0.4≤S / L≤0.75, not only can the cloth wrapping bracket 1 be stretched smoothly, but also it is conducive to the elastic deformation of the cloth wrapping bracket 1 when it is stretched.

[0036] To sum up, the deformation structure of the cloth wrapping bracket 1 is achieved by opening a structural hole on the turning structure 2, and making the direction of the first axis of the structural hole the same as the length direction of the cloth wrapping bracket 1, and the length of the first axis is greater than the length of the second axis. Since the turning structure 2 is formed by extending and bending one end of the cloth wrapping bracket 1, the structural strength of the cloth wrapping bracket 1 is weakened, so that the cloth wrapping bracket 1 can undergo elastic deformation when it is stretched, thereby solving the problem of cracking at the turning point when the cloth wrapping bracket 1 is stretched during assembly of the speaker.

[0037] Embodiment 2:

[0038] See also Figure 4 , the difference between this embodiment and embodiment 1 is that the first structural hole 4 is different. In this embodiment, the first structural hole 4 is a composite hole formed by combining one or more basic holes, and the basic hole is any one of a polygonal hole, a circular hole, and an elliptical hole. The composite hole formed by the combination also has a first axis, and the first axis is the longest axis of the composite hole, and the direction of the first axis is the same as the first direction.

[0039] The use of composite holes not only ensures that the structural strength of the cloth-wrapping bracket 1 is weakened, but also enriches the types of the first structural holes 4, thereby improving the aesthetics of the speaker.

[0040] Embodiment 3:

[0041] See also Figure 5 The difference between this embodiment and embodiment 1 is that the first structural hole 4 is different. In this embodiment, the first structural hole 4 is an irregular hole with an irregular contour. Preferably, the irregular hole is a hole that can be closely laid in a plane, and the irregular hole also has a first axis, and the first axis is the longest axis of the composite hole, and the direction of the first axis is the same as the first direction. By using irregular holes, the types of the first structural holes 4 are enriched, and the aesthetics of the speaker is improved.

[0042] Embodiment 4:

[0043] See also Figure 6 The difference between this embodiment and embodiment 1 is that among the multiple first structural holes 4 located in the second direction, the shapes of any two adjacent first structural holes 4 are different, and the structural holes of different shapes are arranged and combined along the length direction, which can adapt to a more complex stress change environment.

[0044] Embodiment 5:

[0045] See also Figure 7 The difference between this embodiment and embodiment 1 is that a plurality of bending grooves 6 are provided between two adjacent turning structures 2, and the plurality of bending grooves 6 are provided at intervals along the first direction.

[0046] By providing a plurality of bending grooves 6 , the cloth wrapping bracket 1 can be deformed smoothly when the cloth wrapping bracket 1 is bent.

[0047] Embodiment 6:

[0048] See also Figure 8 The difference between this embodiment and embodiment 1 is that it also includes a sound plate 11, and the sound plate 11 is detachable from the cloth wrapping bracket 1. The sound plate 11 is located on one side of the turning structure 2. A second structural hole 9 is opened on the sound plate 11. The second structural hole 9 has a third axis. The direction of the third axis is the same as the first direction, and the length of the third axis is less than the length of the first axis.

[0049] By making the sound plate 11 detachably connected to the cloth wrapping bracket 1, when the cloth wrapping bracket 1 is applied to different sound boxes, the sound plate 11 with different second structural holes 9 can be replaced, thereby meeting the sound production needs of different sound box speakers.

[0050] Embodiment 7:

[0051] See also Fig. 9 This embodiment provides a sound box, including the cloth-wrapped bracket 1 described in any one of Embodiments 1 to 6, and also includes a speaker assembly 8, the speaker assembly 8 includes a diaphragm, and the part of the folded ring of the diaphragm close to the adapter structure is opposite to the opening of the bending groove 6 to avoid the diaphragm folded ring 12 and the cloth-wrapped bracket 1 from interfering with the sound when the diaphragm vibrates for sound.

[0052] Embodiment 8:

[0053] See also Fig.10 This embodiment provides a sound box, including the cloth-wrapped bracket 1 described in any one of Embodiments 1 to 6, and also including a speaker assembly 8 and a cloth 7. The cloth-wrapped bracket 1 encloses a receiving space 3, and the speaker assembly 8 is received in the receiving space 3. The cloth-wrapped bracket 1 is fixedly connected to the speaker assembly 8 by bolts, and the cloth 7 is fixedly connected to the outer side of the cloth-wrapped bracket 1.

[0054] Since the speaker includes the technical solutions of Embodiments 1 to 6, it has at least all the beneficial effects brought by the corresponding embodiments, which will not be described one by one here.
