Abstract

The present invention relates to a raw material which is formed by laminated polymeric membrane and thermoplastic polyurethane and is used for a sound equipment vibrating plate and a preparation method thereof, and especially relates to a device and a method for preparing the raw material for the vibrating plate used for a loudspeaker installed at an intelligent mobile device. The present invention relates to a raw material which is formed by laminated polymeric membrane and thermoplastic polyurethane and is used for a sound equipment vibrating plate and a preparation method thereof, wherein in order to raise acoustic characteristic of the loudspeaker, the existing polymeric membrane is bonded to the thermoplastic polyurethane having good elasticity and softness in a hot laminated way to form the raw material, and compared with the raw material formed by only the polymeric membrane, the raw material of the present invention can raise acoustic quality of a low-frequency band and a high-frequency band. The present invention can obtain an improved effect for the acoustic characteristic that can not be represented by the loudspeaker which only uses the existing polymeric membrane as the raw material of the vibrating plate. Compared with the existing production mode for forming the loudspeaker by vertically placing the polymeric membrane and the thermoplastic polyurethane, the production rate and the reject ratio can be improved.

Description

technical field [0001] The invention relates to a raw material for a vibration plate of an audio equipment laminated with a polymer film and thermoplastic polyurethane and a preparation method thereof, and in more detail, relates to the preparation of a vibration plate for a speaker suitable for being installed in smart mobile devices such as mobile phones and tablet computers. The device and method of the raw material of the board relate to thermally laminating the existing polyether ether copper (PEEK, PolyEetherEtherKeton), polyethylene naphthalate (PEN, PolyethleneNaphthalate), Polymer films such as polyetherimide (PEI, PolyEtherimide), polyimide (PI, Polyimide), polyarylate (PAR, Polyarylate), polycarbonate (PC, Polycarbonate), etc. have good elasticity And soft thermoplastic polyurethane (TPU, ThermoPolyUrethane) bonded raw materials are used to provide laminated polymers that can improve the sound quality of low-frequency bands and high-frequency bands compared to the c...
