The sound basin further includes is connected fixed annulus (21) for the outstanding side (70) with loudspeaker, the annulus (21) it is interior
Circle is connected with the outer ring of the first annular reinforcing rib (20).The cross section of the annulus (21) is rectangle, in other words, table
Face is horizontal, convenient for Nian Jie with horn hanging side (70) so that the first vibrating diaphragm 10 is smoothly fixed on one face, does not generate offset.
First supporting surface 130, the phase are set between the one end of the adjacent side plates 123 of the adjacent V-groove 120
Second supporting surface 140, first supporting surface 130 are set between the other end of the adjacent side plates 123 of adjacent V-groove 120
Arc-shaped edges connect the inner ring of the first annular reinforcing rib 20.
By setting 130 He of the first supporting surface in covering of the fan structure between the both ends of the adjacent side plates of adjacent V-groove
Second supporting surface 140 so that become no matter 120 end of V-groove or middle part can not all be bent after circumferencial direction stress along broken line
Shape solves the problems, such as the lateral deformation between V-groove and V-groove.And first supporting surface 130 and the second supporting surface 140 in fan
Face structure, not only intensity is good, but also the arc-shaped edges regular shape of each supporting surface, can be surrounded by circle, V compared with the prior art
Shape, arc-shaped edges are easily attached fixation, and the inner ring of the arc-shaped edges of each first supporting surface 130 and first annular reinforcing rib 20 can be steady
Fixed reliable connection is fixed, indeformable so as to bear prolonged high-frequency vibration, in addition, a plurality of is in covering of the fan structure substantially
The first supporting surface 130 and the V-groove loudspeaker that form of basic the second supporting surface 140 in covering of the fan structure there is very beautiful regard
Feel effect.
The cylindrical coupler portion 30 is extended by second supporting surface 140, in order to connect voice coil, while can be risen
To the effect of reinforcement structure intensity.
One end of two bevel edges of first supporting surface 130 respectively with two adjacent side plates 123 connects, and described
The radian of the arc-shaped edges of one supporting surface 130 is identical with the inner ring radian of first annular reinforcing rib 20, to seal adjacent V-groove 120
Gap between end, avoids acoustic short circuit.Likewise, two bevel edges of second supporting surface 140 are respectively with adjacent two
The other end of a side plate 123 connects, and to seal the gap between adjacent 120 end of V-groove, avoids acoustic short circuit.
V-groove (120), the first supporting surface 130, the second supporting surface 140, the first annular reinforcing rib of first vibrating diaphragm 10
20th, cylindrical coupler portion 30 and annulus 21 are an integral molding structure, and for ease of distinguishing, Fig. 5 is identified using different hatchings
120th, 130,140,20,21 and 30, actually material all same).Using being bonded, process is multiple for the connection of each several part of usual loudspeaker
Miscellaneous and bonding site intensity is not high, and long-time service is easily deformed, of high cost.The sound basin of the utility model is circumferentially arranged including multiple
The V-groove 120 of cloth, so turnover face is very more, using integral forming process, simple and reliable process, there is no joint intensity
The problem of insufficient, rigidity it is good, will not there is a situation where V-shaped groove 120 along broken line bend.Traditional sound basin, inner ring are glued with voice coil
Connect, by the vibration of voice coil sound basin driven to vibrate, so as to sounding, the utility model by the bottom of the first vibrating diaphragm 10 one into
One cylindrical coupler portion 30 of type, rigidity is good, Nian Jie with voice coil by cylindrical coupler portion 30, improves bond area, so as to
The intensity of abutting edge is improved, avoids diaphagras, the first vibrating diaphragm 10 can not bend along broken line and deform.
The radial direction of first supporting surface 130 can be not parallel with the upper seamed edge 122 of V-shaped groove, and with the footpath of annulus 21
Not parallel to direction, as shown in Figure 5 a, the first supporting surface 130 is used as a transition so that V-shaped groove 120 and first annular reinforcement
The angle of joint is unlikely to too lofty between muscle 20, ensures structural strength in the case of frequent vibration.Certainly, in some realities
It applies in example, the radial direction of first supporting surface 130 also can be parallel with the radial direction of annulus 21.
First reinforcing rib 40 can also be set on the inner wall of first vibrating diaphragm 10 or on outer wall, to enhance the structure of sound basin
Intensity and rigidity avoid diaphagras, bend deformation along broken line.
In the first embodiment, first reinforcing rib 40 is arranged on the top of inner wall of the first vibrating diaphragm 10 or the top of outer wall
Portion.As shown in fig. 6, in the present embodiment, the first reinforcing rib 40 is arranged on the top of the outer wall of the first vibrating diaphragm 10, and is circular ring shape.
The strength and stiffness of sound basin can further be strengthened by the first reinforcing rib 40 so that sound basin can minimize, is lightening, very suitable
It shares in the very high loudspeaker of sound basin rigidity requirement, such as on earphone (such as In-Ear, PlayGear Stealth).
The second reinforcing rib 50 is provided in the middle part of the middle part of the inner wall of first vibrating diaphragm 10 or outer wall, is strengthened by second
Muscle 50 can effectively strengthen the structural strength at 10 middle part of the first vibrating diaphragm.Preferably, the second reinforcing rib 50 is circular ring shape, be conducive to increase
Intensity on strong circumferencial direction.
The bottom of inner wall or the bottom of outer wall of first vibrating diaphragm 10 are provided with the 3rd reinforcing rib 60, strengthen by the 3rd
Muscle 60 can effectively strengthen the structural strength of 10 bottom of the first vibrating diaphragm.Preferably, the 3rd reinforcing rib 60 is circular ring shape, be conducive to increase
Intensity on strong circumferencial direction.
In a second embodiment, as shown in fig. 7, first reinforcing rib 40 is twined from the inner wall bottom spiral of the first vibrating diaphragm 10
Around at the top of inner wall, alternatively, the first reinforcing rib 40 from the outer wall bottom spiral winding of the first vibrating diaphragm 10 to outer wall top, for changing
It, the first reinforcing rib 40 in the present embodiment is spiral reinforcing rib, plays in first embodiment 40,50 and 60 work
With.
In the third embodiment, the sound basin further includes the second vibrating diaphragm in trumpet type；Second vibrating diaphragm is arranged on
On the inner wall of one vibrating diaphragm 10, the outer wall of the second vibrating diaphragm connects with the upper seamed edge 122 of the first vibrating diaphragm V-shaped groove 120.So similary enhancing
The strength and stiffness of sound basin.
In the fourth embodiment, the second vibrating diaphragm is arranged on the outer wall of the first vibrating diaphragm 10, the inner wall of the second vibrating diaphragm and first
The lower seamed edge 121 of vibrating diaphragm V-shaped groove 120 connects.So equally enhance the strength and stiffness of sound basin.
The sound basin can be made of paper, lighter weight, and the prices of raw materials are cheap, can effective control cost.
The sound basin can also be made of metal, and had preferable rigidity, further, light-weight metal be may be employed and be made,
Such as metallic aluminium, sound basin can be made to thinner lighter, so as to further improve its sensitivity, better tonequality effect can be obtained
Fruit.
Certainly, which can also be made of aluminium alloy, composite material or carbon fiber etc., and rigidity is very good and light-weight,
Sound basin is thinner lighter.
Use above specific case is illustrated the utility model, is only intended to help to understand the utility model, and
Not limiting the utility model.For those skilled in the art of the present invention, the think of according to the utility model
Think, several simple deductions, deformation can also be made or replace.
