As shown in fig. 1 to 2, the present invention provides a novel composite sound film 100, which includes more than one base layer 10 and more than one composite layer 20. Specifically, the present embodiment includes a base layer 10 and a composite layer 20. The base layer 10 comprises a base layer ball top 11, a base layer folding ring 12 and a base layer overhanging fringe outer ring 13 which are sequentially arranged from inside to outside, the composite layer 20 is in a hollow design, and a plurality of hollow holes 30 which penetrate through the surface of the composite layer up and down are arranged on the surface of the composite layer. The composite layer 20 is laminated on the base layer 10. The composite layer 20 may be formed of a different material and thickness from the base layer 10.

The hollow holes 30 reduce the weight of the composite layer 20, so that the sound film product is lighter; while the base layer 10 provides strong structural support for the voice film product. The two are superposed to form a composite sound film, when the sound film product is applied to a loudspeaker, the sound film product is more easily driven by a voice coil, and the vibration frequency and the response speed of the sound film product are obviously improved. The hollow composite layer 20 with different materials and thicknesses can be combined with the base layer 10 strongly and weakly to delay the high-frequency trend of the acoustic curve to a certain extent, so that the sound sensation presented by the sound film product is richer and fuller.
