Problems solved by technology

However, although the polyether ether ketone in the crystalline state can guarantee the reliability of the diaphragm, it is currently unable to fully meet the requirements of the product for high acoustic performance, and the f0 of the diaphragm formed by polyetheretherketone in the crystal state is also too high. Meet the product's technical requirements for low f0

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 and figure 2 As shown, the speaker vibration system includes a diaphragm 1 and a voice coil 2 combined with one side of the diaphragm 1. The voice coil 2 vibrates up and down in the magnetic gap formed by the magnetic circuit system of the speaker after being connected to an electric signal. The vibration of the voice coil 2 It can simultaneously drive the diaphragm to vibrate to produce sound. Some characteristics of the vibrating membrane 1, including rigidity, material, etc., will affect the effect of the sound produced by its vibration. The diaphragm of this embodiment is composed of at least two layers of polyetheretherketone (PEEK) material base film. PEEK has rigidity and flexibility, outstanding fatigue resistance, high tensile strength, and good durability. High temperature / low temperature characte...

Abstract

The invention discloses a loudspeaker vibration system. The loudspeaker vibration system comprises a vibrating diaphragm and a voice coil integrated at one side of the vibrating diaphragm, wherein the vibrating diaphragm comprises at least two layers of polyetheretherketone base diaphragms, and the vibrating diaphragm comprises at least one layer of crystalline polyetheretherketone base diaphragm and at least one layer of non-crystalline polyetheretherketone base diaphragm. The vibrating diaphragm is of a structure formed by combination of the crystalline polyetheretherketone base diaphragm and the non-crystalline polyetheretherketone base diaphragm, acoustic performance of the vibrating diaphragm is improved, and the f0 of products is lowered, thus the sounding effect of products can be improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker vibration system. Background technique [0002] The speaker vibration system includes a diaphragm and a voice coil combined on one side of the diaphragm. The diaphragm in the prior art is formed with a single-layer structure or a multi-layer composite structure, so that the specific acoustic performance of the speaker diaphragm can be adjusted according to specific requirements. . As the requirements for loudspeakers become higher and higher, the performance requirements of the prior art for the diaphragm are also higher and higher, so it is necessary to find a diaphragm material that can meet the requirements for such high acoustic performance. [0003] As an improvement, the polyetheretherketone composite diaphragm material is mostly used at present. In order to ensure the reliability of the speaker, the polyether ether ketone material in the cry...
