Self-pressure-relief waterproof middle-pasted sound production film

Abstract

The invention provides a self-pressure-relief waterproof middle-pasted sound production film, and relates to the field of equipment waterproofing. The self-pressure-relief waterproof middle-pasted sound production film includes a first sounding membrane. A first adhesive layer is tightly pressed on the top of the first sound production film, a waterproof breathable film is arranged on the top of the first adhesive layer, a second adhesive layer is tightly pressed on the top of the waterproof breathable film, a second sound production film is arranged on the joint portion of the second adhesivelayer, and the front face of the second sound production film is covered with a strippable waterproof testing covering film. According to the self-pressure-relief waterproof middle-pasted sound production film, through arranging the air leakage pressure holes in the first sound production film and the second sound production film, the material solves the reliability problem of bonding of the waterproof breathable film and the loudspeaker sounding middle sticker. The material can be applied to various waterproof equipment with a closed rear cavity or insufficient air leakage pressure, can be in any shape, is laminated on one surface of the sandwich composite sounding middle sticker material to seal the air leakage pressure hole, and is simple to peel off and convenient to use after an airpressure test is completed.

Description

technical field [0001] The invention relates to the technical field of equipment waterproofing, in particular to a self-pressure-relieving waterproof mid-stick sound-emitting membrane. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. [0003] However, in the existing loudspeaker structure at present, because the waterproof and breathable membrane is directly attached to the loudspeaker sounding paste, the adhesive surface of the waterproof and breat...
