Embodiment Construction

[0013] The following are specific examples of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these examples.

[0014] The invention provides the application of a new type of resin material as a diaphragm of an audio driver, and the new type of resin material is one of polyethylene naphthalate, polyimide, polyether ether ketone or polyethylene naphthalene dicarboxylate Blend of ethylene glycol formate and polyether ether ketone.

[0015] Preferably, the novel resin material is a mixture of polyethylene naphthalate and polyether ether ketone, based on the total mass of the novel resin material, wherein polyethylene naphthalate (PEN) The content is 30wt%-60wt%, and the content of polyetheretherketone (PEEK) is 40wt%-70wt%.

[0016] Among them, polyethylene naphthalate (PEN) is formed by polycondensation of dimethyl 2,6-naphthalene dicarboxylate (NDC) or 2,6-naphthalene dicarboxylic acid (NDA...

Abstract

The invention provides application of a novel resin material for making a sound box driver diaphragm. The invention additionally provides the sound box driver diaphragm and a preparation method thereof. The diaphragm comprises a dome and a vibrating edge. The dome is made of a titanium metal material. The vibrating edge is made of the novel resin material. By using the novel resin material to make the diaphragm, the defect of insufficient elastic modulus and internal damping of the existing diaphragm can be overcome, the transient vibration of the diaphragm is improved, the sound sensation is enabled to be richer, more delicate and more intensive, and the sound emitted by a driver product which adopts the diaphragm is enabled to have higher penetrability and clarity.

Description

technical field [0001] The invention belongs to the application field of polymer materials, and in particular relates to the application of a novel resin material as a diaphragm of an audio driver. Background technique [0002] The sound radiated from the driver should only reproduce the added signal in theory, but in fact, in addition to the fundamental frequency signal, there are sounds of other frequencies in the radiated sound, which sounds abnormal. Caused by the transient vibration difference of the diaphragm. At present, the diaphragm material structure of the driver is mainly based on a single simple dome, and the dome is generally made of titanium metal. [0003] Since the driver is in a high-power state for a long time, the overall elastic modulus and internal damping of the diaphragm are insufficient, which often leads to distortion and diaphragm bursting of the driver under high power. Although the commonly used titanium dome diaphragm has a high modulus of ela...
