Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] refer to figure 1 , the structure of the reinforced loudspeaker diaphragm 1 in this embodiment includes airgel 2 and diaphragm 1, the above-mentioned airgel 2 is pasted on the surface of the above-mentioned diaphragm 1, wherein the above-mentioned airgel 2 is the The gel is made by dehydration. Specifically, dehydration is carried out within a shaped frame, and the dehydrated airgel 2 is made into an airgel 2 whose size and shape meet the requirements by cutting or molding processing methods, so that it becomes an integrally formed airgel 2; The glue 2 itself has the characteristics of light weight and high rigidity, and the integrally formed airgel 2 is attached to the surface of the above-mentioned diaphragm 1, so that the diaphragm 1 also has the characteristics of light weight and high rigidity. The coil ...

Abstract

The invention discloses a structure for strengthening a loudspeaker diaphragm, a method for strengthening the loudspeaker diaphragm and a loudspeaker, wherein the structure for strengthening the loudspeaker diaphragm comprises a diaphragm and an aerogel, and the aerogel is attached onto the surface of the diaphragm. The structure for strengthening the loudspeaker diaphragm, the method for strengthening the loudspeaker diaphragm and the loudspeaker, provided by the invention, aim at enabling the diaphragm to simultaneously have the characteristics of high sensitivity and good high pitch effect.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to a structure and a method for strengthening the loudspeaker diaphragm and the loudspeaker. Background technique [0002] As a device that generates sound through electric current, the moving coil speaker has a diaphragm driven by a coil, and the diaphragm is driven by the coil to generate controllable vibrations, thereby causing air vibration and realizing sound playback. Existing loudspeakers require the diaphragm to work stably and consistently at a frequency of 20Hz to 20000Hz. However, due to material limitations of the existing diaphragm, a highly rigid diaphragm will increase the thickness of the diaphragm and increase the quality of the diaphragm. Although the increase in rigidity will improve the treble performance of the diaphragm, it will cause the problem of reduced sensitivity; and the rigidity of the diaphragm with high sensitivity is low, making the treble effect...
