In addition, according to the difference of the specific structure of the cavity groove 12, or according to the difference of the design of the speaker product with specific specification, in the embodiment, the specific structure of the cavity groove 12 has two forms, one is the scheme that the cavity groove 12 is arranged on the inner bottom surface of the installation cavity 11 as shown in fig. 1. In another embodiment, as shown in fig. 2 and 3, the cavity groove 12 is disposed on the back bottom surface of the mounting cavity 11. Both forms can meet the requirements of practical application, and only the two forms are designed with a certain difference in specification.
As shown in fig. 1, 2, and 3, the elastic support mechanism 5 is disposed in the mounting cavity 11, and the bottom of the diaphragm 2 is connected to the top of the elastic support mechanism 5, so that the diaphragm 2 is erected on the opening of the mounting cavity 11 of the bracket 1. The structure of this example can make elastic support mechanism 5 whole hide in installation cavity 11, makes elastic support mechanism 5's side all around, is difficult for receiving external force extrusion, avoids the speaker to take place the impaired condition of elastic support mechanism 5 in the installation application. The lower end of the voice coil 3 is connected to the magnet 4, and the top of the voice coil 3 is connected to the middle of the bottom surface of the diaphragm 2.
As shown in fig. 8, 9 and 11, the elastic support mechanism 5 is formed by stacking a plurality of elastic ring units 51, and each elastic ring unit 51 is formed by stacking an upper half ring body 511 and a lower half ring body 512. Because the invention adopts the structural design, in the practical application process, only the elastic ring units 51 with different diameters or specifications are produced, and the elastic supporting mechanisms 5 with different shapes or specifications can be assembled to meet the requirements of practical application. For example, as shown in fig. 8, a cylindrical elastic support mechanism 5 may be assembled; alternatively, as shown in fig. 11, a tapered elastic support mechanism 5 may be assembled; alternatively, the reverse tapered elastic support mechanism 5 may be assembled, or as shown in fig. 12 to 15, the elastic support mechanism 5 having a specific shape may be assembled.

In addition, in order to facilitate the routing of the electric wire 20 electrically connected to the voice coil 3 and to prevent the electric wire 20 from affecting the operation of the elastic support mechanism in the speaker, as shown in fig. 16 and 17, a lead wire notch 516 is further provided on the outer circumferential edge 513 or the inner circumferential edge 515. Through the design of the lead bayonet 516, in application, as shown in fig. 18 or fig. 19, the wires 20 can be regularly routed along the outer wall or the inner wall of the elastic supporting mechanism, which is not only regular and free of interference, but also does not affect the normal operation of the elastic supporting mechanism.
