Abstract
The utility model relates to a double magnetic circuit body of a telephone receiver or a loudspeaker, which at least consists of an annular outer magnet steel, a magnetizer, and a pole chip, the central coaxial line of the magnetizer is provided with cylindrical inner magnet steel and the pole chip. On the premise that the utility model does not increase the volume, the magnetic field intensity is effectively improved.
Description
Affiliated technical field
The utility model belongs to the pickoff group in International Classification of Patents, i.e. H04R, particularly double magnetic circuit receiver or twin magnetic circuit speaker.
Background technology
At present, public receiver or loud speaker, mainly contain vibrating diaphragm, with voice coil loudspeaker voice coil, annular magnetic steel, the T iron of vibrating diaphragm center fixation be magnetic conductor, voice coil loudspeaker voice coil is suspended in the magnetic gap between T iron and the magnet steel.According to theory, the size of voice coil loudspeaker voice coil stressed F in magnetic field, with the magnetic induction density B of magnetic gap, the size of the audio signal I of conductor length L of voice coil loudspeaker voice coil own and input is proportionate.Under the constant condition of L, I, improve B and can increase F.Therefore the way that increases the magnet steel volume commonly used improves F.
The utility model content
The purpose of this utility model is to improve magnetic structure to improve the magnetic flux density of voice coil loudspeaker voice coil, thereby the double magnetic circuit body of receiver or loud speaker is provided.
New technical scheme is disclosed as back: the double magnetic circuit body of receiver or loud speaker, at least contain pole piece sheet, magnet steel and magnetic conductor, the center that it is characterized in that the magnetic conductor of annular outer steel, coaxial line are equipped with cylindrical interior magnet steel, and said inside and outside magnet steel has cylindrical respectively and the ring pole chip.
According to the sample that such scheme tries, compared with the prior art, its magnetic flux density has had raising by a relatively large margin, and sample mean has improved 1 times.
Description of drawings
Fig. 1 is the sketch of an embodiment of the utility model, wherein:
1, the pole piece sheet of interior magnet steel;
2, the pole piece sheet of outer steel;
3, outer steel;
4, magnetic conductor;
5, interior magnet steel.
Fig. 2 is an extended pattern schematic diagram of the present utility model.
Embodiment
From accompanying drawing 1 as can be seen, the double magnetic circuit body of receiver or loud speaker contains outer steel 3 and the magnetic conductor 4 and the pole piece sheet 2 of annular at least, the center of magnetic conductor 4 also coaxial line be fixed with cylindrical in magnet steel 5 and pole piece sheet 1 thereof.The thickness of the thickness of interior magnet steel 5 and outer steel 3 is identical but polarity is opposite.
If adopt special-purpose magnet charger, the utility model can also expand to the whole magnet steel 6 that the cross section is the mountain font; Save magnetic conductor, see Fig. 2.
Claims (2)
1, the double magnetic circuit body of a kind of receiver or loud speaker contains pole piece sheet, magnet steel and magnetic conductor at least, it is characterized in that the center of the magnetic conductor [4] of annular outer steel [3], coaxial line is equipped with cylindrical interior magnet steel [5], said internal-external magnetic steel [5,3] has cylindrical respectively and ring pole chip [1,2].
2, the double magnetic circuit body of receiver as claimed in claim 1 or loud speaker it is characterized in that the thickness of interior magnet steel [5] is identical with the thickness of outer steel [3], but polarity in contrast.
