Abstract
The invention discloses a moving-magnetic type ultrathin telephone receiver, comprising a case which is internally provided with a vibrating diaphragm, wherein the vibrating diaphragm is compounded with permanent magnet material powder, the wall of the case arranged at one side of the vibrating diaphragm is provided with a planar primary coil being taken as a primary voice coil and a damping hole, the wall of the case at the other side of the vibrating diaphragm is provided with a planar repeating coil being taken as a repeating coil and a sound hole, and a connection capable of increasing the total magnetic field is formed between the planar main coil and the planar repeating coil. The telephone receiver has the advantages of compact structure and is convenient for automatic production, besides, the vibration mode formed in the invention is better than a common cone vibration mode.
Description
Technical field
The present invention relates to a kind of receiver, especially a kind of moving-magnetic type biplane coil ultra-thin telephone receiver.
Background technology
The operation principle of common receiver is in the magnetic field being made up of permanent magnet systems, is hanging the voice coil loudspeaker voice coil of an effect of not stressing, and voice coil loudspeaker voice coil is mutually bonding with a vibrating basin.Vibrating basin is to be generally cone-shaped, and its conelet is mutually bonding with vibrating basin, and auger is bonding with receiver basin frame.In the time that tone currents passes through voice coil loudspeaker voice coil, the electric current flowing through on voice coil loudspeaker voice coil, can be subject to the effect of Ampere force in the magnetic field in permanent magnet system, can make vibrating basin vibration and sounding.Due to scientific and technical development, more and more higher to the requirement of receiver, should receiver itself, it is miniature, ultra-thin, it,, in concrete manufacturing, can meet and can utilize automatic production line again, organizes production.And mono-Ma permanent magnetism parts---Li is as the magnet of Nd iron boron (NdFeB) magnet in actual production, just occupied larger space, and the bonding of coil and vibrating membrane needs meticulous pure artisan craftsmanship to complete, this has just become to utilize the restriction bottleneck of automatic production line tissue production.
Summary of the invention
The invention provides a kind of compact conformation and be convenient to the high tone quality moving-magnetic type ultrathin telephone receiver of automated production.
The present invention adopts following technical scheme:
A kind of moving-magnetic type ultrathin telephone receiver, comprise: the housing of built-in vibrating diaphragm, on vibrating diaphragm, there is again powder of permanent-magnet material, on the shell wall of housing that is positioned at vibrating diaphragm one side, be provided with plane main coil and the damping hole as keynote circle, on the shell wall of housing that is positioned at vibrating diaphragm opposite side, be provided with plane repeater coil and the sender as repeater coil, between plane main coil and plane repeater coil, form being connected of can making that total magnetic field strengthened.
The present invention is different from receiver in the past:
1. coil of the present invention is fixed, is different from common receiver voice coil loudspeaker voice coil and moves;
2. the magnetic thin film of the embedding powder of permanent-magnet material (as: neodymium iron boron powder) that magnetization of the present invention forms afterwards moves.It is motionless being different from common receiver magnetic circuit system;
Due to coil of the present invention be the vortex type of plane close around coil, thereby it can make the superthin structure that more general receiver is more thin;
4. in order to improve film when vibration, form the compliance of system between film and housing, the present invention has adopted to have in a side of shell has another Side of Air Filter, shell to have damping hole damping hole (phono-equalizer unit hole) upper topped with O type damping screen on sender sender.
5. coil of the present invention has been made twin coil form.But a coil is keynote circle, another is repeater coil, both number of turns differences, and in addition, the direction of the winding current is noted that and will makes total magnetic field unanimously and be strengthened;
6. the vibrating diaphragm that contains powder of permanent-magnet material (as: neodymium iron boron powder) can adopt special manufacture method.For example: a kind of is powder of permanent-magnet material (as: neodymium iron boron powder) through having wrapped up, in the material of the polymeric membrane of mixing material shape, through hot pressing, stretching film forming for; One is on one deck polymeric membrane film, make to be uniformly distributed thereon with the powder of permanent-magnet material (as: neodymium iron boron powder) of glue or colloid parcel by the mode such as lacquering technique, stencil, use again thereon one deck polymeric membrane (with lower membrane be homogeneity or non-homogeneity all can) merge by hot pressing and lower floor's polymeric membrane, at this moment powder of permanent-magnet material (as: neodymium iron boron powder) is sandwiched in two polymeric membrane, forms an even thin layer being hedged off from the outer world.Powder of permanent-magnet material (as: neodymium iron boron powder) film can be formed with ferromagnetic film after magnetization is magnetized.
7. solving magnetic field and do not concentrate and reduce leakage field, is to put forward the high performance problem that first will consider in such design, and at present common original design, the leakage field of coil magnetic field is large, and coil magnetic field is concentrated poor performance.In the present invention, with be powder of permanent-magnet material (as: NdFeB ferromagnetism powder), and powder of permanent-magnet material (as: the strong magnetic of NdFeB) layer is placed on to the center of vibrating diaphragm, in addition, or soft iron or the silicon steel sheet (if the iron shell of use does not need) that can make magnetic field concentration are put into again at coil magnetic field central area, because its magnetic resistance is little, can make magnetic field concentration, so just may make the effect of mass action get well.
8. in design of the present invention, the effect of the magnetic field producing by extraneous current signal to center powder of permanent-magnet material (as: the strong magnetic of NdFeB) layer, and powder of permanent-magnet material (as: the strong magnetic of NdFeB) layer is moved, if powder of permanent-magnet material (as: the strong magnetic of NdFeB) layer is thinner, it is a diaphragm vibration that has uniform active force in diaphragm center; If powder of permanent-magnet material (as: the strong magnetic of NdFeB) layer is thicker, can be considered it is " tabular " thing of a diaphragm center equivalence, the film of surrounding is the equal of flexible connection, and this has just become to be similar to the vibration mode that surrounding is flexible connection " plate " vibration.Two kinds of vibration modes, no matter be any, its effect is all good than the vibration mode of common round Cone formula vibrating diaphragm.
9. in design of the present invention, can first magnetize vibrating diaphragm, also can in the time being assembled into half parts, magnetize, there will not be the problem that magnetization is difficult.The cavity that the present invention designs because there being a constant volume exists, and can have the effect of organ for resonance, can improve tonequality.
10. in the present invention's design, adopt symmetry shell structure, housing first, simple, the Yi Hang of mounting plane coil on second, and plane diaphragm is without meticulous viscose glue operation, be designed with to be like this beneficial to and complete with mechanization, automatic mode, therefore, can solution emit a lot of manual personnel, and can improve work efficiency.
