Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1 to 2, the low temperature resistant rubber edge cone for the loudspeaker comprises a bottom cone 1, a cone 14 and a rubber edge 2 which is integrally formed with the cone 14;

as shown in fig. 1, two at least rubber strips 3 of fixedly connected with on the rubber limit 2, this rubber strip 3 one end runs through papaw 14 and end basin 1, fixedly connected with supplies the firm piece 4 that rubber strip 3 got into on the end basin 1, the cavity has been seted up on the

firm piece

4, 2 both sides on rubber limit are provided with fixed strip 5, this

fixed strip

5 and 3 plug-in connection of rubber strip, it has the firm groove that supplies the fixed strip 5 to get into to run through on the firm piece 4 both ends terminal surface, in actual operation, through inserting the fixed strip 5 on rubber strip 3 through the firm groove, and through firm piece 4 and the contact of fixed strip 5, reach the fixed of rubber strip 3, increase rubber strip 3 and pass through 2 papaw 14 on the rubber limit, reach the fixed of papaw 14 and chassis.
