Abstract

The invention relates to the technical field of technology and application of composite materials of fabric and film materials, in particular to a fabric composite film and its preparation method and application. The fabric composite film includes cloth and resin film, and the cloth and resin film are coated and bonded Adhesive, the material of the resin film includes TPU, PC, PEEK, PP, PEI, PEN, PTFE, PU, ​​PVA, silica gel, rubber, acrylic, the resin film is rolled up, and the adhesive glue is coated, and the glue amount is 50 ‑180g / m3, the roller tension on the resin film is 1.5‑3.5kgf / m2, step 2: paste the cloth on the resin film, the lamination tension of the cloth is 1.2‑2.7kgf / m2, which can improve the suspension of the cloth The audio performance of the low frequency and intermediate frequency of the side speaker improves the internal damping and vibration compliance of the speaker diaphragm, reduces abnormal sound, and reduces the distortion rate, which improves the electrical efficiency of the speaker.

Description

technical field [0001] The invention relates to the technical field of technology and application of a composite material of fabric and film material, in particular to a fabric composite membrane and a preparation method and application thereof. Background technique [0002] Loudspeaker, also known as "horn", is a very commonly used electroacoustic transducer device, which can be seen in electronic circuits that produce sound. The loudspeaker is the weakest device among electronic components, but it is the most important device for sound effects. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. The sound quality of the speaker is the most important inspection index of the speaker, and a very important reason that affects the sound quality is the membrane vibration. Among them, the hanging edge ...
