Problems solved by technology
Due to the irregular wrinkled texture of the crystallized amorphous PEEK diaphragm, some folds have sufficient depth to accommodate glue, and some folds have a small depth so that the glue cannot effectively infiltrate and affect the non-crystalline PEEK. The overall wetting effect will further affect the wetting effect and adhesion of the surface of the peripheral fixed part and the diaphragm support part, the central part and the hard composite layer glued and bonded, resulting in the failure of waterproof and airtight
In addition, when the diaphragm vibrates, the irregular surface wrinkle texture will produce a slight split vibration, which will reduce the listening yield and affect the overall performance of the speaker

The invention provides a vibrating diaphragm, which comprises at least one layer of non-crystalline polyether-ether-ketone material, and is characterized in that the vibrating diaphragm comprises a central part, a folding ring part and a fixing part, and the crystallized vibrating diaphragm is provided with wrinkles; a plurality of first reinforcing ribs are arranged on the central part, a plurality of second reinforcing ribs are arranged on the fixed part, the extending directions of the first reinforcing ribs and the second reinforcing ribs are the same, and the extending directions of the first reinforcing ribs and the second reinforcing ribs correspond to the overall extending direction of the wrinkles; the first reinforcing ribs are parallel to one another, and the second reinforcingribs are parallel to one another. By arranging the first reinforcing rib and the second reinforcing rib, the influence on the performance of the vibrating diaphragm due to crystallization of amorphouspolyether-ether-ketone is remarkably reduced, and the binding power of the vibrating diaphragm is increased. Meanwhile, the problem of segmentation vibration is reduced, and the overall acoustic performance of the vibrating diaphragm is improved.
Description
technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a vibrating membrane and a sounding device. Background technique [0002] As a device capable of converting electrical energy into sound energy, a speaker has been widely used in mobile terminals such as mobile phones, computers, and pads. The performance of the speaker will directly affect the sound reproduction effect of the terminal device; and the diaphragm, as one of the key components of the speaker's sound, has higher and higher requirements for its quality, and is gradually developing in the direction of high strength, high sound quality, and low distortion. , and the structural requirements for the speaker diaphragm are more stringent. At present, the polyetheretherketone raw materials commonly used in diaphragms are mostly amorphous materials with better diaphragm forming effects. Since the voice coil will generate heat when it vibra...
