It states.
The present invention provides a kind of acoustic mode group, and this acoustic mode group is able to ascend the assembly precision of vibrating diaphragm ontology, raising sound
Learn the acoustical behavior of mould group.
In the present embodiment, acoustic mode group includes: vibrating diaphragm ontology 10 and shell 20, and the vibrating diaphragm ontology 10 has the folding of annular
Ring portion 11 and fixed part 12.The ring portion 11 is to the side of the vibrating diaphragm ontology 10 protrusion, and the fixed part 12 is from the folding
The edge of ring portion 11 extends outwardly.It is understood that ring portion 11 and fixed part 12 are integrally formed on vibrating diaphragm ontology 10
, fixed part 12 is located at the periphery in ring portion 11, for fixing the vibrating diaphragm ontology 10.
Particularly, the vibrating diaphragm ontology is by including that the substrate of UV particle is molded.UV particle is can be in appropriate wave
Under long UV light irradiation, cause substrate solidification, to realize the bonding of material.A certain amount of UV particle is added in substrate,
The vibrating diaphragm ontology being molded can according to need under the irradiation of UV light carried out with other component it is be bonded.For the kind of substrate
Class, can be the transparent or semitransparent material such as silica gel, resin, and the present embodiment is without limitation.
Further, the acoustic mode group further includes shell 20.The shell 20 has accommodating chamber 21, the accommodating chamber 21
Periphery be formed with the link slot 22 around the accommodating chamber 21, accommodating chamber 21 described in 10 face of vibrating diaphragm ontology is arranged, institute
Fixed part 12 is stated to be fixedly connected with the link slot 22.In embodiment as illustrated in figs. 1 and 2, the vibrating diaphragm ontology 10 can
It is fixed in the link slot 22 by bonding agent.In this way, the vibrating diaphragm ontology of injection molding and the link slot of shell are by bonding
After agent is tentatively fixed, under the UV light irradiation of appropriate wavelength, it can further solidify, promote the connection between vibrating diaphragm ontology and shell
Intensity.
Compared to traditional by after vibrating diaphragm ontology and teething ring single injection-molded, then teething ring directly fixed with shell
The mode of connection.Acoustic mode group provided by the embodiment eliminates the setting of teething ring, avoids teething ring shadow due to deformation, fracture
Ring the assembly precision of acoustic mode group.Acoustic mode group provided by the invention, vibrating diaphragm ontology therein are by the material containing UV particle
Be molded, the vibrating diaphragm ontology under the irradiation of UV light, can with the link slot of shell further combined with.Facilitate reduce save at
Originally, the difficulty of assembly is reduced, the acoustical behavior of sounding device is obviously improved.
Optionally, the region that the fixed part 12 is connect with the link slot 22 has coarse surface.Vibrating diaphragm ontology with
There are many connection types of shell, and fixed part is fixedly connected by the present embodiment using bonding agent with the link slot of shell.Wherein, Gu
Determining the region that portion is connect with the link slot has coarse surface, can increase the bond area of bonding agent, coarse table in this way
The gap that face is formed is also beneficial to accommodate bonding agent, enhances the bonding strength of vibrating diaphragm ontology and link slot.
In embodiment as depicted in figs. 1 and 2, the shell 20 includes upper casing 24 and middle shell 23, and the middle shell 23 has
Have an accommodating chamber 21, the vibrating diaphragm ontology 10 is connect with the link slot 22 of 21 periphery of accommodating chamber, the upper casing 24 and it is described in
The fastening of shell 23 constitutes sounding device.
Wherein, the rough surface on fixed part 12 towards 22 side of link slot can have a variety of structures form.For example, this is thick
Rough surface can be distributed for topping shape, or be also possible to the formal distribution of salient point on the surface of fixed part.The present embodiment
The structure of rough surface on fixed part is not specifically limited, those skilled in the art can select as needed.
Further, the quality of the UV particle accounts for the 10%-30% of the substrate mass.Content is 10%-30%'s
After UV particle is mixed with substrate, the vibrating diaphragm ontology formed by Shooting Technique is under the irradiation of the UV light of appropriate wavelength, Ke Yiyin
Hair vibrating diaphragm ontology further solidifies, i.e., firm combination may be implemented in the fixed part of vibrating diaphragm ontology and link slot.Compared to tradition
Technique, facilitate reduce Material Cost.
Optionally, the substrate is silica gel.On the one hand, silica gel material is mostly transparent material, selects silica gel material as base
Material, the absorption convenient for UV particle to UV light.On the other hand, the vibrating diaphragm ontology formed after silica gel and the injection molding of UV particle is had high-elastic
Property, high mechanical strength；Meanwhile the chemical property of this vibrating diaphragm ontology is stablized, use temperature range is big, good weatherability.Certainly, originally
Field technical staff also can according to need, the material for selecting other chemical property stable as substrate, the present embodiment to this not
It is limited.
In the present embodiment, the overall size of the link slot 22 is identical as the overall size of the vibrating diaphragm ontology 10.Such as Fig. 2
With shown in Fig. 3, the vibrating diaphragm ontology 10 and 20 face of shell, the fixed part 12 of vibrating diaphragm ontology and the 22 phase knot of link slot
It closes.In assembly, vibrating diaphragm ontology 10 is fixed in link slot 22 first, fixed part 12 and the link slot 22 of vibrating diaphragm ontology pass through
Bonding agent realizes preliminary fixation.And then vibrating diaphragm ontology is irradiated with UV light or makes vibrating diaphragm ontology into one with the mode of thermosetting
Step solidification, realization vibrating diaphragm ontology and shell are combined closely.Finally obtained acoustic mode group, the globality of vibrating diaphragm ontology and shell
More preferably, the assembly precision of vibrating diaphragm ontology is improved, the acoustical behavior for promoting acoustic mode group is facilitated.
Optionally, the width of the fixed part 12 and the link slot 22 is of same size.As shown in Figures 2 and 3, described
The fixed part of vibrating diaphragm ontology is fittingly disposed in link slot, and the globality of vibrating diaphragm ontology and link slot is more preferable, improves acoustic mode
Space utilization in group.
Another aspect of the present invention also provides a kind of processing method of acoustic mode group, as shown in figure 4, this method comprises: to
UV particle is added in substrate, injection molding vibrating diaphragm ontology provides shell, on the housing by vibrating diaphragm ontology bonding, vibration
Membrane body can be realized with the link slot on shell by bonding agent preliminary fixed.And then to the vibrating diaphragm sheet being bonded on shell
Body is irradiated solidification to it by UV light source；Alternatively, being heated to the vibrating diaphragm ontology being bonded on shell.Above two side
Formula can be such that the vibrating diaphragm ontology containing UV particle is closely fixedly connected under the irradiation of UV light with link slot.Added using this
The assembly precision of the acoustic mode group of work method is improved, and acoustical behavior is more preferably.
Although some specific embodiments of the invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to being illustrated, the range being not intended to be limiting of the invention.The skill of this field
