Electrical connection；Form chamber between vibrating diaphragm 30 and two flexible coil dishes 1,2, described in go out acoustic aperture 11 and make institute
State chamber to be in communication with the outside.
Have employed a kind of flexible receiver, the speaker of specific embodiment of the invention technical scheme, due to
Which employs the vortex densely packed coil 1,2 of flexibility, and the diaphragm structure 3 of flexibility, so it has relatively
Good flexibility, can bend, thus can well meet some electronic product for flexible electronic unit device
The demand of part；Additionally, flexible receiver in this patent, speaker, compare existing receiver, raise
For sound device, structure is simpler, advantageously in industrialization produce and advantageously reduce cost and
Controlling product quality, its tonequality receiver more typically to get well, therefore to have the highest practical value.
Preferably in technical scheme, described flexible coil dish 1,2 includes flexible base board, and is attached to institute
State the vortex densely packed coil inside flexible base board；Described flexible base board and vortex densely packed coil are at flexible PCB
Photo-etching processes is used to be made on plate.And two the vortex densely packed coil of flexible coil dish in flexible coil
Dish axis projection direction is nested against one another, comb teeth-shaped occlusion is arranged, and so can preferably offset stress not
Harmony, certain nested against one another, comb teeth-shaped occlusion said herein, refer to along coil panel axis projection to same
Effect in one plane, the D coil shown in C coil shown in solid in Fig. 3 and dotted line, Ke Yifen
It is not considered upper flexible coil dish 1 and lower flexible coil dish 2.As it is shown on figure 3, make rotation angle α=π, i.e.
The position contrary with coil C swirl direction is rotated counterclockwise to, by two lines by parallel for two coil neutralization circle D
Circle moves to same plane as new compensation coiling model.The line in figure is replaced respectively by compensating coiled wire-wound coil
Circle C and coil D, owing to the structure spatially comb teeth-shaped of coil former is engaged, can eliminate coaxial vortex
The unsymmetry of current-carrying coil magnetic force.Why this kind of collocation structure can offset the lack of uniformity of stress,
Main cause is exactly that collocation structure is in a center of symmetry about initial point.Be equivalent to coil translate into from first quartile
Third quadrant.It is symmetrical about x-axis symmetry or y-axis that change direction of winding is equivalent to coil, is equivalent to line
Circle has translated into the second quadrant or fourth quadrant from first quartile.So, according to centrosymmetric principle, instead
Should compensate the most each other to the second quadrant of coiling and the coil of fourth quadrant.If as shown in Figure 4, by four
Individual quadrant, the structure of four kinds of coils is all used.Four coils are superimposed upon in approximately the same plane as Fig. 5
Shown in, remain to keep stress symmetrical.If all enclosed around n, the coil of first quartile and fourth quadrant will
End to end, the coil of the second quadrant and third quadrant also can be end to end.Now by head end invariant position,
The end of each coil is many around 1/4 circle, and the most each coil encloses around (n+1/4), it is achieved that first, second,
3rd, the end to end concatenation of fourth quadrant coil.This method can meet back-roll, reversal connection, series connection
Connected mode, the flow direction of four coil currents is the most identical, and the magnetic field of generation is overlapped mutually, simultaneously stress
Uniformly along axis, and coupling part need not unnecessary cabling, direct vertical perforating.More than repetition
Coil is the structure of unit, can arbitrarily multilamellar cascade in order to make magnetic field superimposed in theory,
To add high-intensity magnetic field.
