Description

Technical Field

[0001] The utility model relates to the technical field of support plates of loudspeakers, in particular to a novel support plate. Background Art

[0002] Speakers, commonly known as horns, are used to complete the conversion between electrical signals and sound signals and are energy conversion devices. Speakers usually include a vibration system and a magnetic circuit system. The vibration system includes a diaphragm, a voice coil, and a support sheet mounted outside the voice coil. The support sheet is used to prevent the voice coil and diaphragm from polarizing and is one of the indispensable parts of the speaker.

[0003] However, the corrugations of the supports currently used all have the same size, which results in a small linear amplitude and no limit on the maximum amplitude, causing the speaker to have large distortion and prone to mechanical sound when the power signal is increased.

[0004] Therefore, a new type of support is designed to solve the above problems. Utility Model Content

[0005] In view of the above existing technical problems, the utility model provides a new type of support plate, which increases the linear amplitude range and limits the maximum amplitude by changing the size of the corrugations on the support plate.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A novel support sheet includes a support sheet body, characterized in that the support sheet body is composed of an inner edge portion, a corrugated portion and an outer edge portion which are connected as one piece from inside to outside, the corrugated portion is composed of a variable corrugated area and a small corrugated area, the variable corrugated area and the small corrugated area are connected as one piece, and the size of the corrugations set in the variable corrugated area gradually increases from inside to outside,

[0008] The variable corrugated area is connected to the inner edge portion, and the small corrugated area is connected to the outer edge portion.

[0009] The size of the corrugations arranged in the small corrugation area is smaller than the size of the corrugations in the variable corrugation area.

[0010] Specifically, the support body is connected to the outer periphery of the voice coil in the speaker, and the other end of the support body is connected to the basin frame of the speaker.

[0011] Beneficial effects of the utility model:

[0012] The utility model designs a new support piece, and the corrugated part on the support piece body is composed of a variable corrugation area and a small corrugation area connected as one body. The corrugations arranged in the variable corrugation area are increasingly larger in size from the inside to the outside, and the rigidity decreases as the corrugation size increases, and increases as the corrugation center distance increases. Therefore, as the corrugations of the support piece increase gradually, the rigidity can remain unchanged, thereby increasing the linear amplitude range. When the small corrugations near the edge are taken, the corrugation size becomes smaller, and the rigidity increases, thereby limiting the maximum amplitude. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] like Figure 1 and 2 As shown, the novel support sheet includes a support sheet body 1, which is characterized in that the support sheet body 1 is composed of an inner edge portion 11, a corrugated portion 12 and an outer edge portion 13 connected from inside to outside, and the corrugated portion 12 is composed of a variable corrugated area 121 ( Figure 2 The area with a large circle in the middle) and the small ripple area 122 ( Figure 2 The variable ripple zone 121 is connected to the small ripple zone 122 as a whole, the variable ripple zone 121 is connected to the inner edge portion 11, and the small ripple zone 122 is connected to the outer edge portion 13. The size of the ripples set in the variable ripple zone 121 gradually increases from the inside to the outside, and the size of the ripples set in the small ripple zone 122 is smaller than the size of the ripples in the variable ripple zone 121.

[0025] Example 2

[0026] When using the utility model, if Figure 3The support body 1 of the present application is connected to the outer periphery of the voice coil 100 in the speaker, and the other end of the support body 1 is connected to the basin frame 101 of the speaker. When the speaker is working, the voice coil 100 makes axial reciprocating motion. One end of the support body 1 is connected to the voice coil 100 and fixed, so the support body 1 and the voice coil 100 make axial reciprocating motion together (limiting the radial motion of the voice coil 100), and the other end of the support body 1 is fixed to the basin frame 101, without relative motion.

[0027] Because the rigidity of the corrugation of the support sheet body 1 decreases with the increase of the corrugation size and increases with the increase of the corrugation center distance, in this design scheme, the corrugated portion 12 on the support sheet body 1 is designed to be composed of a variable corrugated area 121 ( Figure 2 The area with a large circle in the middle) and the small ripple area 122 ( Figure 2 The two parts (the area with a small circle in the middle) are connected as one body, and the corrugation size designed in the variable corrugation area 121 increases gradually from the inside to the outside, so the rigidity can remain unchanged, thereby increasing the linear amplitude range. In the small corrugation area 122 near the edge 13, the corrugation size becomes smaller, and its rigidity increases, thereby limiting the maximum amplitude.

[0028] The following is a linear amplitude diagram to illustrate:

[0029] like Figure 4 , when the corrugated support pieces are of equal size in the traditional method, the linear amplitude range is smaller, that is, there are fewer flat areas, so the distortion is larger;

[0030] like Figure 5 When all progressive corrugated supports are used, the linear amplitude range is larger, that is, the flat area is wide, but there is no limit to large amplitude;

[0031] like Figure 6 When the utility model is adopted, it has a larger linear amplitude range, that is, while the bottom flat area is wide, the rigidity in the large amplitude area is increased, and the large amplitude is limited.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
