The second connection portion 12 of the elastic member 10 is connected to the housing, and the voice coil 20, the elastic member 10, and the housing are assembled. In another embodiment, the first connector 11 is connected to the drag cup 80 and the second connector 12 is connected to the housing. In other embodiments, the first connection portion 11 is connected to the drag cup 80 and the second connection portion 12 is connected to the yoke, or the first connection portion 11 is connected to the voice coil 20 and the second connection portion 12 is connected to the yoke.
As shown in fig. 10, specifically, in one embodiment, the application device 100 includes a vibration unit 40, a magnetic circuit system 50, and a housing for mounting and fixing the vibration unit 40 and the magnetic circuit system 50; wherein, the vibration unit 40 includes a diaphragm 60 and a voice coil 20 combined below the diaphragm 60; the magnetic circuit system 50 includes an upper magnetic conductive plate, a magnet, and a lower magnetic conductive plate, wherein the upper magnetic conductive plate and the lower magnetic conductive plate are magnetic conductive structures for correcting magnetic lines of force generated by the magnet, the magnetic circuit system 50 forms a magnetic gap 51, and the voice coil 20 is disposed in the magnetic gap 51 of the magnetic circuit system 50.

Compared with the conventional elastic component 10 in the shape of a sheet, the elastic component group 30 of the application device 100 of the present embodiment has a different molding manner and/or cross-sectional dimension and/or material of at least one elastic component 10 from other elastic components 10, so as to adapt to different environments inside the application device 100, and the compatibility is good. For example, among the at least three elastic components 10 of the elastic component group 30, some elastic components 10 may be linear, narrow strip-shaped or sheet-shaped structures formed by integrally stamping metal plates, so that the flatness and dimensional tolerance are easier to control, the product yield is high, and the elastic component group can adapt to an environment with a large stress, and other elastic components 10 may adopt linear structures formed by winding single-strand metal wires, or linear structures formed by winding double-strand metal wires, so that the elastic component group is easy to manufacture and can adapt to an environment with a small stress. For another example, in the elastic component group 30, the cross-sectional dimension of one of the elastic components 10 is larger than the cross-sectional dimensions of the other elastic components 10, that is, the cross-sectional dimension of one of the elastic components 10 is made larger than the cross-sectional dimensions of the other elastic components 10 by widening, so that the stress concentration on the elastic component 10 is reduced, the occurrence of fracture is avoided, the normal use of the elastic component 10 is ensured, and the normal use of the application device 100 is further ensured.
In addition, one of the elastic components 10 in the elastic component group 30 is widened, so that the vibration frequency of the whole elastic component 10 can be changed, resonance is eliminated, and the product performance is optimized. And/or, in the elastic component group 30, one of the elastic components 10 has two cross sections with different sizes, that is, one of the elastic components 10 can be arranged in a variable diameter manner, specifically, in one of the elastic components 10, a region with larger stress can be locally widened, so that the cross section size of the region with larger stress is increased, the stress concentration phenomenon of the region is reduced, the occurrence of fracture is avoided, and resonance is eliminated. In the preferred embodiment, all the elastic members 10 of the elastic member assembly 30 are widened, thereby ensuring the normal use of the entire elastic member assembly 30 and the overall elimination of resonance.
In the application device 100 of the present embodiment, the elastic component 10 can be changed according to different adaptability of the internal environment of the application device 100, and has good compatibility, simple and convenient manufacturing process, simplified manufacturing process, high manufacturing efficiency and reduced manufacturing cost. In addition, the elastic member 10 of the present embodiment does not increase the height of the application device 100 in the vertical direction, occupies a small space, and is advantageous for thinning of products. In addition, in the process that the elastic component 10 displaces along the vertical direction along with the vibration unit 40, the deformation part 13 is elastically deformed to be large enough, even if the vibration unit 40 vibrates to displace greatly, the compliance of the elastic component 10 is kept good, enough displacement can be provided, the vibration of the vibration unit 40 is not influenced, and the product performance is optimized.
In one embodiment, one of the elastic members 10 in the elastic member assembly 30 is formed by sheet-shaped stamping, specifically, a plate is integrally stamped to form a narrow sheet-shaped structure. In the preferred embodiment, all the elastic members 10 of the elastic member assembly 30 are integrally formed by stamping, which is beneficial to mass production and increases the manufacturing efficiency. In other embodiments, one of the elastic components 10 of the elastic component assembly 30 may be an integral punch-formed structure, and the other elastic components 10 may be formed by winding a wire-wound structure, specifically, a linear structure formed by winding a single-strand metal wire, or a linear structure formed by winding a double-strand metal wire, which is flexible and convenient.
In this embodiment, in each elastic component 10, the deformation portion 13 is a planar structure, and the deformation portion 13, the first connection portion 11 and the second connection portion 12 are located in the same horizontal plane, so that the elastic component 10 is a planar structure as a whole, and compared with the existing sheet-shaped elastic wavy elastic component 10, this embodiment improves the overall flatness of the elastic component 10, further reduces the height of the application device 100 along the vertical direction, and realizes the design concept of product thinning.
Further, the number of the elastic component groups 30 of the present embodiment is plural, the plural elastic component groups 30 are arranged at intervals along the height direction of the framework 21, and all the elastic components 10 of each elastic component group 30 are located in the same horizontal plane. It can be understood that at least three elastic components 10 of one elastic component group 30 are all located in the same horizontal plane, which not only enhances the centering effect on the vibration unit 40, but also has good mechanical stiffness Kms symmetry and flatness, and meets the requirement of large displacement fatigue. The elastic component groups 30 are uniformly arranged along the height direction of the framework 21 at intervals, and compared with one elastic component group 30, the elastic component groups 30 enhance the centering effect on the vibration unit 40 on one hand, reduce stress concentration on the other hand, correspondingly reduce the wire diameter of the elastic component 10 and are easier to manufacture.
Furthermore, the elastic members 10 of each elastic member set 30 are vertically displaced from the elastic members 10 of the other elastic member sets 30.
