ULTRATHIN, WATERPROOF AND SOUND-PERMEABLE COMPOSITE MODULE

The invention discloses an ultrathin, waterproof and sound-permeable composite module, which comprises a waterproof and sound-permeable composite module body, wherein the waterproof and sound-permeable composite module body comprises a metal matrix, an adhesive and a waterproof sound-permeable membrane, the metal matrix is bonded to the waterproof sound-permeable membrane by the adhesive, the metal matrix is provided with a step, the step is integrally formed with the metal matrix, the step is divided into a first step and a second step, and the adhesive is arranged as a single-component epoxy system thermosetting adhesive. In place of traditional die-cut articles, the ultrathin, waterproof and sound-permeable composite module of the invention is bonded to a product, thus fundamentally solving the problems that the traditional die-cut articles have poor uniformity, difficulty in mass production and wide adhered glue.
