Description
Technical field
The present invention relates to the plane diaphragm of loudspeaker, especially earphone speaker.
Background technology
Loudspeaker is commonly called as " loudspeaker ", is a kind of electro-acoustic transducer device for converting electrical signals to acoustical signal.Plane diaphragm is raised
Sound device is one kind in loudspeaker, and traditional planar diaphragm speaker is will to set conductor coils on very thin plane diaphragm
(aluminium, copper, silver, gold etc.) is placed in magnetic field, and vibrating diaphragm moves up and down when conductor coils pass through electric current, and sends sound.It is existing to raise
Wire has major part to be straight line and arranged in horizontal or vertical direction in plane diaphragm in sound device, and these linear wires lead to again
The wired in series of bending is crossed into an entirety.The straight line portion of conductive coil and its have larger sky between dogleg section
Gap, due to the variant conductor that is larger, and being largely collectively aligned of the mechanical strength of metallic conductor and film（Straight line portion）So that
Plane diaphragm its mechanical strength bad student's notable difference on the direction to be intersected with the part conductor, causes vibrating diaphragm in vibration processes
It is middle nonlinear diaphagras occur, deteriorate tonequality so as to produce non-linear distortion.So existing loudspeaker plane diaphragm
Improved necessity be present.
The content of the invention
The technical problem to be solved in the present invention is, there is provided a kind of improved plane diaphragm and has this plane diaphragm
Loudspeaker.
The technical solution adopted for the present invention to solve the technical problems is：The plane diaphragm of Non-Linear Vibration can be suppressed, wrapped
Vibrating diaphragm body is included, conductor coils are provided with the vibrating diaphragm body, the conductor coils include parallel portion, and parallel portion includes some
The parallel straight wire of bar, the parallel straight wire of each bar is sequentially connected in series by bending wire forms the conductor coils, in vibrating diaphragm body
Some metal reinforcings are also equipped with, the direction and the direction of straight wire that metal reinforcing described in each bar is laid are cross-shaped
State.
The plane diaphragm of Non-Linear Vibration can be suppressed as previously described, the laying direction of reinforcement described in each bar and straight wire
Direction it is vertical.
The plane diaphragm of Non-Linear Vibration can be suppressed as previously described, formation is free after conductor coils are laid on vibrating diaphragm body
Gap region, metal reinforcing described in each bar are distributed in void area.
The plane diaphragm of Non-Linear Vibration can be suppressed as previously described, part reinforcement is set with the straight wire cross-contact
Put.
A kind of loudspeaker, it is provided with the plane diaphragm as described in preceding any one.
Implement technical scheme, there is following beneficial effect：It is different from straight wire direction by setting direction
Reinforcement, lower the non-linear distortion brought of diaphagras, lift the tonequality of loudspeaker.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
Fig. 1 is the schematic diagram of the utility model embodiment one；
Fig. 2 is the schematic diagram of the utility model embodiment two；
Mark is described as follows in figure：
1st, conductor coils；2nd, straight wire；3rd, reinforcement.
Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now compares accompanying drawing and describe in detail
The embodiment of the present invention.
The plane diaphragm for suppressing Non-Linear Vibration as shown in Figure 1-2, including set described in vibrating diaphragm body on vibrating diaphragm body
Conductor coils 1 are equipped with, the conductor coils 1 include parallel portion, and parallel portion includes some parallel straight wires 2, and each bar is parallel
Straight wire 2 is sequentially connected in series by bending wire forms the conductor coils 1, and some metal reinforcings are also equipped with vibrating diaphragm body
3, the laying direction of metal reinforcing 3 described in each bar and the direction of straight wire 2 intersect（Referred to both directions are inconsistent, uneven
OK）.Existing plane diaphragm coil cabling mode has rectilinear wires that are a variety of, but having substantial amounts of horizontal or vertical arrangement,
Which results in plane diaphragm rectilinear wire move towards it is crisscross on the shortcomings that mechanical strength is poor be present, and lay direction
The upper metal reinforcing 3 intersected with straight wire 2 can effectively solve the problem that this problem.
The laying direction of each bar reinforcement 3 with parallel straight wire 2 be on direction it is mutually perpendicular, so can be at utmost
The upper bad mechanical strength in the two directions for reducing plane diaphragm.And in the specific setting of reinforcement 3, two realities in this case
Applying example is arranged using some shorter metal reinforcings 3, it is such the advantages of be：Compared to one it is linear
Overall reinforcement 3 walks setting, and a plurality of short metal reinforcing 3 can effectively reduce the overall weight of vibrating diaphragm, avoid because of vibrating diaphragm
Overall weight rise has influence on the problem of loudspeaker high frequency response effect and transient response variation.
Embodiment one, two specifically illustrates two kinds of different paving modes, a plurality of short metal reinforcing 3 on direction
All be with straight wire 2 in vertical state.And in the embodiment one shown in Fig. 1, formed after laying conductor coils 1 on vibrating diaphragm body
There is void area, metal reinforcing 3 is distributed in void area described in each bar.Although i.e. conductor coils 1 and the side of metal reinforcing 3
To being in intersecting, but both are not intersect discontiguous in itself, and the advantage so laid is that technique is simpler, product yield
It is high.In embodiment two shown in Fig. 2, except void area have set reinforcement 3 in addition to, it is most important that part reinforcement 3 with
2 direct square crossing of straight wire contact is set, and each bar reinforcement 3 in the part is arranged by the way of length is interlocked, so
The advantages of be can more directly effective diaphagras, inhibition is best, but technological requirement is slightly higher.
Deficiency caused by existing coil cabling mode is overcome using the loudspeaker of plane diaphragm described in this case, can be most
The non-linear distortion that the attenuating diaphagras of big degree is brought, lift the tonequality of loudspeaker.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various changes, combination and change.Within the spirit and principles of the invention, made
Any modification, equivalent substitution and improvements etc., should be included within scope of the presently claimed invention.
