Problems solved by technology

[0003] In the existing speakers, the diaphragm structure is mainly a single-layer polymer material, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyether ether ketone (PEEK), Polyetherimide (PEI), polyphenylene sulfide (PPS), polyarylate (PAR), thermoplastic polyurethane elastomer (TPU), etc., and some diaphragms are composite structures of two or more of the above materials. However, the diaphragms of the above materials generally have problems such as weak strength and poor uniformity.
Specifically, it is difficult to form a single-layer polymer material diaphragm, while the multi-layer composite diaphragm of the above-mentioned polymer material has inconsistent uniformity during molding, which easily affects the acoustic performance of the product.
In addition, it is difficult for the above-mentioned polymer material diaphragm to have good strength and toughness at the same time, and it is prone to phenomena such as membrane rupture, and the compliance of the diaphragm is not ideal; moreover, when the polymer material diaphragm works for a long time, it will Due to temperature changes, the diaphragm with poor temperature stability is prone to deformation and softening, which affects product quality and service life

Embodiment 1

[0028] refer to Figure 1-Figure 3 Shown is the structure of the diaphragm assembly of Embodiment 1 of the present invention. In this embodiment, the base layer of the diaphragm is a single layer of polymer material, and the middle part of the diaphragm is the base layer of the diaphragm.

[0029] Such as Figure 1-Figure 3 As shown, the diaphragm assembly includes a diaphragm 1 , and the diaphragm 1 includes a middle part 3 and a ring part 2 surrounding the outer periphery of the middle part 3 . The diaphragm assembly also includes a reinforcing part 4 arranged in the middle of the diaphragm 1. The reinforcing part 4 is combined with the upper side or the lower side of the middle part 3, and is generally polyether ether ketone (PEEK), thermoplastic polyurethane elastomer (TPU ) or a single-layer or multi-layer structure composed of other polymer materials can effectively enhance the performance of the diaphragm 1 at high frequencies.

[0030] The diaphragm 1 includes a diap...

Embodiment 2

[0039] Figure 4 Shows the second embodiment of the diaphragm assembly of the present invention, this embodiment is basically the same as the first embodiment, the difference lies in:

[0040] The middle part 3 of the diaphragm 1 is a composite structure of the diaphragm base layer 5 and the silica gel layer 6 , that is, the silica gel layer 6 is bonded to the surfaces of the ring part 2 and the middle part 3 at the same time, and is injection molded.

Embodiment 3

[0042] Figure 5 Shows the third embodiment of the diaphragm assembly of the present invention, this embodiment is basically the same as the first embodiment, the difference lies in:

[0043]The diaphragm base layer 5' is two polymer material layers, including a polyetheretherketone (PEEK) material layer 7 and a thermoplastic polyurethane elastomer (TPU) material layer 8. It should be noted that the polymer material layer is not limited to the above-mentioned Two kinds, you can choose polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyetheretherketone (PEEK), polyetherimide (PEI), polyphenylene sulfide Any two of (PPS), polyarylate (PAR), thermoplastic polyurethane elastomer (TPU). It should be noted that, during specific implementation, the vibrating film base layer 5' is not limited to the above-mentioned materials, and may also be other two kinds of polymer material layers.

[0044] Such as Figure 5 As shown, an adhesive layer 9 is provided between th...

Abstract

The invention discloses a vibration film component, and relates to the technical field of electro acoustical products. The vibration film component comprises a vibration film, wherein the vibration film comprises a middle portion and a fold ring portion which wraps around the periphery of the middle portion. The vibration film furthermore comprises a vibration film base layer and a silica gel layer, wherein the silica gel layer is integrated in the vibration film base layer at least partially, the vibration film base layer is a polymer material layer, the silica gel layer is integrated in the surface of the fold ring portion, and the silica gel layer and the polymer material layer are injection molded. The vibrating film component achieves recombination of the silica gel layer and the polymer material layer by arranging the silica gel layer in the surface of the fold ring portion, and thereby improves compliance of the vibration film, enhances chemical stability and adaptability to temperature of the vibration film, optimizes acoustic performances, and improves products yield rate.

Description
