Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment 1
As depicted in figs. 1 and 2, a kind of single-point support props up sheet, and including the first lamellar body 1 and the second lamellar body 2, the first lamellar body 1 and the second lamellar body 2 are in circular, and the center of circle of the first lamellar body 1 and the second lamellar body 2 overlaps, and is provided with gap between the first lamellar body 1 and the second lamellar body 2;
Support band 3 connection by many between first lamellar body 1 and the second lamellar body 2, support band 3 and be located in gap.
First lamellar body 1 and the second lamellar body 2 are two sticky bits, namely it is connected with sound basin assembly in use, simultaneously, first lamellar body 1 is connected with support 4, the skeleton of the second lamellar body 2 voice coil loudspeaker voice coil 5 is the same strong point, therefore, the first lamellar body 1, support band 3 and the second lamellar body 2 effect under, it is achieved that the connection of voice coil loudspeaker voice coil 5 and vibrational system.
The number with 3 that supports between first lamellar body 1 and the second lamellar body 2 is even number, and multiple support band 3 is positioned at gap and is uniformly distributed. Wherein, support the quantity of band 3 and be limited mainly by the bore of speaker product and voice coil loudspeaker voice coil 5 brocade silk thread 7 amplitude limits. Support the shape with 3 to be limited by bore and speaker stroke. Arranging two bright and beautiful silk threads 7 on voice coil loudspeaker voice coil 5, generally, two bright and beautiful silk threads 7 are symmetrical arranged, and in gap, even number supports band 3, it is possible to reserve symmetrically arranged gap accordingly, in speaker group leader's system, it is possible to support is with 3 be staggered with brocade silk thread 7, is independent of each other.
Supporting band 3 in strip, and support the band 3 tilted settings in gap, its two ends are connected with the first lamellar body 1 and the second lamellar body 2 respectively.
Preferably, first lamellar body the 1, second lamellar body 2 is identical with the thickness supported with 3, and its thickness is 0.075～0.2mm. Wherein, for thickness for 0.1mm, the bore of speaker can be controlled in 31mm, and height 12.46mm, F0 are 140HZ, pliable Cms > 1.75.
Time specifically used, first lamellar body 1 is bonded on support 4, second lamellar body 2 is bonded on sound basin, the skeleton of voice coil loudspeaker voice coil 5 is bonded on sound basin equally, being distributed between support 4 and voice coil loudspeaker voice coil 5 so that support band 3, the line transfer amplitude of the bright and beautiful silk thread 7 of voice coil loudspeaker voice coil 5 is moderate, just avoids support band 3, during use, support and with 3 and brocade silk thread 7, the vibrational system of speaker is played a supportive role.
This single-point support props up sheet 6 and is applicable to all of loudspeaker, is especially applicable to small-bore Herba Cladoniae verticillatae, and profile can be circular, it is possible to is strip, or other irregular loudspeaker; The shape propping up sheet is not limited to lamellar, can also be ripple struction in space permission situation, or other; Two sticky bits propping up sheet are mutually bonding with 9 groups of sound basin respectively, constitute 3 sheet systems of single-point support band. Strip support band 3 quantity and the size of propping up sheet can be adjusted according to needs.
Embodiment 2
As shown in Figure 3 and Figure 4, a kind of speaker, including support 4 and voice coil loudspeaker voice coil 5, support 4 is provided with single-point support and props up sheet 6, the first lamellar body 1 connection bonding with support 4;
First lamellar body 1 and the second lamellar body 2 are provided with sound basin assembly, and sound basin assembly includes ring 8 and sound basin 9, and the first lamellar body 1 is connected with the marginal adhesion of ring 8, and the skeleton sound basin 9 of voice coil loudspeaker voice coil 5 connects, and on the second lamellar body 2, the marginal adhesion with sound basin 9 is connected.
Wherein, the first lamellar body 1 overlaps with the sticky bit of support 4 and the sticky bit of ring 8 and the first lamellar body 1.
First lamellar body 1 shares a strong point with sound basin group, jointly vibrational system is supported, and wherein, the bottom surface of the first lamellar body 1 is bonding with support 4, and the marginal adhesion of end face and ring 8, the first lamellar body 1 both the above bonding plane overlaps. Although the first lamellar body 1 shares a sticky bit with ring 8, but, owing to whole single-point support props up the relatively thin of sheet 6, relatively soft, it is pliable greatly, therefore, second lamellar body 2 still can share a sticky bit with sound basin 9, namely on the edge of sound basin 9 and the second lamellar body 2, end face is bonding, and the skeleton of voice coil loudspeaker voice coil 5 is same bonding with the edge of sound basin 9, thus forming the same strong point.
During assembling, firstly the need of the position determining voice coil loudspeaker voice coil 5, afterwards, carry out single-point support again and prop up the location of sheet 6,, magnetic conductor bowl 10, main magnetic 11, magnetic conduction sheet 12, anti-magnetic 13 are assembled meanwhile, prop up bonding support 4 and sound basin group on sheet 6 at single-point support, support 4 and magnetic conductor bowl being assembled, the speaker of assembling molding obtains finished product after carrying out the step such as Acoustic detection, pure tone detection respectively.
This speaker greatly reduces the height that speaker is overall, it is simple to develop to direction small-bore, portable. This kind of design can overcome that the single suspension F0 of tradition is high, batch production qualification rate is extremely low, unstable properties, easily by weakness such as humiture affect; This kind of speaker F0 can be adjusted to 140HZ, Cms > 1.7, batch qualification rate is up to more than 98%.
Loudspeaker design adds single-point support and props up sheet 6, both can not change horn profile, performance can be improved again, moreover it is possible to improve loudspeaker stability, it can be seen that the application of this kind of design will be very wide, can horizontal development; Lamellar single-point support props up sheet 6 speaker and can be used for multimedia loudspeaker box, portable loudspeaker box, mini audio amplifier and other speaker products.
Embodiment 3
It is conductive material that single-point support props up the material of sheet 6, and voice coil loudspeaker voice coil 5 line of voice coil loudspeaker voice coil 5 props up the first lamellar body 1 of sheet 6 and is connected with single-point support. Wherein, conductive material can be Copper Foil/aluminium foil etc., when adopting conductive material, single-point support props up sheet 6 and has certain wire-conducting performance, replacing brocade silk thread 7 by the electric conductivity of a sheet, vibrational system can be deleted brocade silk thread 7 and be designed, and so vibrational system can be made and more simplify.
Know-why of the present utility model is described above in association with specific embodiment. These describe and are intended merely to explanation principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way. Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes fall within protection domain of the present utility model.
