Description
Technical field
The present invention relates to a kind of many magnetic gap multiple voice coils loudspeakers, the acoustoelectric device belonged in electronic device.
Background technology
Loudspeaker is developed into today, and species is various, is divided into electrodynamic type by operation principle, electromagnetic type, piezoelectric type, electrostatic
Deng；It is divided into Whole frequency band by working band（20~800Hz）, middle pitch（500~6KHz）, high pitch（4K~20KHz）, by radiation mode point
For direct radiator type, horn type, earphone etc., it is divided into internal magnetization, external magnetic type etc. by magnetic circuit form；It is divided into flat-die by vibrating diaphragm shape
Shape, sun flower-shape, taper, top dome shape etc.；It is divided into polymer PET, cone, aluminium film, titanium film etc. by vibrating diaphragm material.Make a general survey of Lin Linzong
Total loudspeaker, DYN dynamic loudspeaker is in the majority, analyzes DYN dynamic loudspeaker, has a gapped magnetic field, in this gap
In laid a voice coil loudspeaker voice coil.
The content of the invention
The task of the present invention is to invent a kind of loudspeaker, multiple gapped magnetic fields are produced in the magnetic field of this loudspeaker, is pacified
Multiple voice coil loudspeaker voice coils have been put, the power of loudspeaker is improved many times.
The technical solution adopted for the present invention to solve the technical problems is：A kind of many magnetic gap multiple voice coils loudspeakers, include
Magnet, soft iron, vibrating membrane, centring disk, voice coil loudspeaker voice coil, ring, support, lead, the magnet constitute closed magnetic with the soft iron
Road, the closed magnetic circuit, which is constituted, is：Outside is tubular magnetic pole, the polar orientation of the tubular magnetic pole and the tubular field axis
Unanimously, there is magnetic pole in the axle center of tubular magnetic pole, and the polar orientation of the magnetic pole magnetic pole is consistent with the magnetic pole axis, the tubular magnetic
Pole and the two ends of magnetic pole are that the magnet rings different by some diameters replace with soft iron ring and are nested together and constituted in a plane
Disc closure, the polar orientation of the magnet ring magnetic pole is vertical with the magnet ring axis, the magnet ring that is alternately nested together and
There is gap between soft iron ring, form the voice coil loudspeaker voice coil for thering is diameter to match with spacer ring in spacer ring, each spacer ring, this
A little voice coil loudspeaker voice coils are connected together by two voice coil loudspeaker voice coil planes on the outside of voice coil loudspeaker voice coil and maximum voice coil loudspeaker voice coil barrel surface, and described two voice coil loudspeaker voice coil planes are by institute
State magnet ring, soft iron ring and magnetic pole to be enclosed between two voice coil loudspeaker voice coil planes, the outer rim connection centring disk of described two voice coil loudspeaker voice coil planes
Inner edge, the outer rim of the centring disk connects support, and one of plane of described two voice coil loudspeaker voice coil planes connects the inner edge of vibrating membrane,
The outer rim of the vibrating membrane connects ring, and the outer rim of the ring connects the outer rim of support.The tubular magnetic pole, magnetic pole, magnet ring pass through
Support is fixedly connected integrally.The wiring phase of all voice coil loudspeaker voice coils of described two voice coil loudspeaker voice coil planes be it is consistent, the tubular magnetic pole,
Magnetic pole, the magnetic direction of the generation of magnet ring are that closure is consistent.Magnet ring and soft iron ring between the tubular magnetic pole and magnetic pole
Quantity accounting is：It can be entirely magnet ring, can also be entirely soft iron ring, acceptable part magnet ring, part soft iron ring alternately go out
It is existing.Tubular magnetic pole of the present invention, magnetic pole, the magnetic flux of magnet ring be it is equal, be so conducive to the utilization in magnetic field.This hair
Bright principle is, by the magnetic field of closed magnetic circuit, produces multiple gapped magnetic fields, and each gapped magnetic field constitutes a spacer ring,
A voice coil loudspeaker voice coil is laid in each spacer ring, all voice coil loudspeaker voice coils connection phase is identical, i.e.,：When all voice coil loudspeaker voice coils lead to positive electricity, own
Voice coil loudspeaker voice coil direction of displacement is consistent（Certainly logical negative electricity is also consistent）.The present invention has two remarkable advantages：One is that the present invention has n voice coil loudspeaker voice coil,
If transient magnetic field power suffered by each voice coil loudspeaker voice coil is f, then making a concerted effort suffered by two voice coil loudspeaker voice coil faces is nf, because power is that (s is fs/t in formula
Displacement), so the power of the original same specification loudspeaker of power ratio of the present invention is increased about（N-1）Times（Conventional equipment is excavated
Potentiality can only increase by 0.2 times or so --- and i.e. 20% is just good）, such increase is surprising, significant, apparent
's.Two be that the two ends of two voice coil loudspeaker voice coil planes at tubular magnetic pole and magnetic pole two ends have centring disk constraint voice coil loudspeaker voice coil can only be in magnetic
Post axis direction is moved, and will not be produced the situation of disalignment, be also implied that, voice coil loudspeaker voice coil operation will not be with gapped magnetic field side
The magnet ring of edge（Or friction damage --- coil just rubs disconnected the contact of soft iron ring after damage）, add the life-span of voice coil loudspeaker voice coil ---
That is life-span of loudspeaker.Common loudspeaker is used in the close vibrating membrane side only one of which centring disk of voice coil loudspeaker voice coil when for a long time
When vibrating membrane geometry is asymmetric afterwards, it is easy to voice coil loudspeaker voice coil is wandered off, friction damage voice coil loudspeaker voice coil.Three be that distortion reduces, due to the present invention's
Vibration film quality does not almost increase, and the magnetic field force that vibrating membrane is moved is added several times, it can be seen from Newton's second law, shakes
Dynamic film is easier to be controlled by audio voltage.
The beneficial effects of the invention are as follows one is the increase in the life-span of loudspeaker, and two be to reduce distortion, and three be more same than original
The power of specification loudspeaker about manyfold, such power increase is surprising, significant, obvious.
