Description
Technical field
The utility model relates to diaphragm of loudspeaker fields, more particularly to a kind of diaphragm of loudspeaker based on PEEK.
Background technique
How the loudspeaker of sound equipment reduce the noise of its output, to reach the presentation of complete message, determine sound equipment listener most
Obtained message effect eventually；During general loudspeaker transmit message, a vibrating membrane can be disposed on loudspeaker, so that sound
Sound can be transmitted effectively.
With the continuous improvement of the market demand, mobile phone gradually develops to slimming direction, and its sound quality is required to get over
It is better to come, and this requires the acoustical devices in mobile phone to develop towards small-sized, slim, high tone quality.Vibrating diaphragm is the acoustics device such as loudspeaker
The core component of part, the requirement to its acoustical behavior also just increase accordingly.
Vibrating diaphragm in relevant technology can be extremely difficult to the transaudient effect of vibrating membrane loudspeaker low frequency with a kind of single film
Fruit, composite diaphragm are a kind of following development trends.Composite diaphragm can pass through the reduction integral material of the adhesive of composite layer
Rigidity, to provide lower f0.Existing composite diaphragm is generally after deployment in the form of sheets and with multilayered structure, such as CN
The patent of 204104123 U discloses the composite diaphragm with five-layer structure.Although it is capable of providing lower f0, however its
Thickness is still larger, and the rigidity of integral material is still higher.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of diaphragm of loudspeaker based on PEEK, rigidity and f0?
It is lower.
The technical scheme adopted by the utility model is
A kind of diaphragm of loudspeaker based on PEEK, including the vibrating diaphragm ontology in full wafer and surfacing, the vibrating diaphragm ontology
It is made of substrate layer with the layer of silica gel for being connected to one side surface of substrate layer is completely covered, the material of substrate layer is PEEK, the silicon
Film surface does not have viscosity, and the layer of silica gel and substrate layer are integrally pressed and molded.
The material of the layer of silica gel is modified silica-gel as a further improvement of the utility model,.
The modified silica-gel is modified add-on type silica gel as a further improvement of the utility model,.
As a further improvement of the utility model, the layer of silica gel with a thickness of 3 μm~20 μm.
As a further improvement of the utility model, the substrate layer with a thickness of 5 μm~20 μm.
The beneficial effects of the utility model are: two layers only with substrate layer and layer of silica gel of the composite diaphragm of the utility model
Structure, while sufficiently low f0And rigidity is conducive to two layers in addition, the silica gel layer surface in composite diaphragm does not have viscosity
The compression molding of structure, it is simpler compared to processing technology for the product of injection molding, it is more efficient.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Specific embodiment
The diaphragm of loudspeaker based on PEEK as shown in Figure 1, including vibrating diaphragm ontology, which is in full wafer after deployment
Shape and surfacing, transportational process vibrating diaphragm ontology can wind in rolls.Vibrating diaphragm ontology is made of double-layer structure, is substrate layer respectively
1 and it is completely covered the layer of silica gel 2 for being connected to substrate layer upper surface, the material of substrate layer 1 is PEEK.By being provided with layer of silica gel,
To reduce the rigidity of composite membrane, and then reduces the rigidity of integral material and improve material heat resistance, and then reduce loudspeaker
The f of vibrating diaphragm0, to reach the low frequency performance for improving the diaphragm of loudspeaker.
Above-mentioned 2 surface of layer of silica gel does not have viscosity, thus the layer of silica gel in embodiment and substrate layer can be and
It is integrated compression molding, for the composite diaphragm product of current injection molding, processing technology is simpler, processing efficiency
It is higher.
Layer of silica gel without viscosity can directly be bought in the market, such as commercially available blue star organosilicon 7460, be also possible to
The processing that vanishing viscosity is carried out on silica gel product, specifically refers to the technical principle of 102897777 B of CN.
It is further preferred that the material of layer of silica gel is modified silica-gel, it is more preferably modified add-on type silica gel.Modified silica-gel
Silica gel is dissolved in organic media, and for system solid content 10% to 50%, elasticity modulus is very low.
It is further preferred that layer of silica gel with a thickness of 3 μm~20 μm, and PEEK substrate layer with a thickness of 5 μm~20 μm.
Integrated compression moldings are carried out with 10 μm of PEEK substrate layers respectively using 5 μm, 10 μm, 15 μm, 20 μm of layer of silica gel,
Form the vibrating diaphragm that following serial number is respectively (1), (2), (3), (4), the impact of performance such as following table.
| Earphone resonant frequency F0 | Low-frequency distortion (300Hz) | Processability | |
| (1) | 535HZ | 16.5% | Well |
| (2) | 495HZ | 15% | Well |
| (3) | 567HZ | 18% | Well |
| (4) | 600HZ | 20% | Well |
The above is the utility model preferred embodiment, is not constituted to scope of protection of the utility model
Limitation.
