The utility model discloses an arc design, the length that has lengthened magnet under the limited circumstances in space, the magnetic circuit of magnet can be for interior magnetic structure, also can be for outer magnetic structure, the utility model discloses can effectively improve magnetic flux density to promoted the efficiency of speaker, it is big to have magnetic flux, and sensitivity is high, advantage that the sound performance is good.
Description
Technical field
This utility model relates to electroacoustic field, specifically, relating to a kind of high magnetic flux magnetic circuit of loudspeaker.
Background technology
Along with the market development of the portable consumer series products such as portable notebook, mobile phone, substantial amounts of electro-acoustic transducing device particularly Microspeaker is widely used, and while less to Microspeaker dimensional requirement, performance is also required to ensure excellent performance.The generally Microspeaker of structure, magnetic circuit system includes washer, Magnet and the yoke combined successively, the big I of Magnet affects the size of magnetic flux, and then directly affect the acoustical behavior of speaker, the operation principle of speaker is to pass through alternating current to voice coil loudspeaker voice coil, moving reciprocatingly relative to magnetic circuit system under the action of a magnetic field that magnetic circuit system produces, voice coil loudspeaker voice coil drives vibrating diaphragm to vibrate together, and vibrating diaphragm is instigated air and sent corresponding sound.
In prior art, under limiting in certain space, magnetic circuit of loudspeaker size can be limited, the magnetic saturation region causing Magnet is less, causes magnetic flux little, few through the magnetic line of force quantity of voice coil loudspeaker voice coil, thus the magnetic field force that causes voice coil loudspeaker voice coil to be subject to is less, the sensitivity of Microspeaker is low, and the phonation efficiency of speaker reduces, the serious lifting constraining speaker acoustical behavior.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can be effectively improved magnetic flux density, thus promotes the high magnetic flux magnetic circuit of loudspeaker of loudspeaker enclosure.
The technical solution of the utility model is as follows:
A kind of high magnetic flux magnetic circuit of loudspeaker, including the washer combined the most successively, Magnet and yoke, described Magnet includes the first Magnet setting up and down and the second Magnet, described first Magnet and described second Magnet are arcuate structure, forming semicircular magnetic gap between described first Magnet and the second Magnet, described first Magnet and the magnetic pole of the second Magnet form vertical magnetic circuit direction on the contrary.
In technique scheme, as optionally, described Magnet is internal magnetic circuit structure, and described first Magnet is formed in one with described second Magnet, and the center of circle of described magnetic gap is positioned at described yoke.
In technique scheme, as optionally, described Magnet is external magnetic circuit structure, and described first Magnet and described second Magnet are disposed on described washer, and the center of circle of described magnetic gap is positioned at outside described yoke.
In technique scheme, described yoke is semicircular structure.
Compared with prior art, the beneficial effects of the utility model are: Magnet is divided into the first Magnet setting up and down and the second Magnet by this utility model, this first Magnet and the second Magnet are arcuate structure, being formed with semicircular magnetic gap between first Magnet and the second Magnet, described first Magnet and the magnetic pole of the second Magnet form vertical magnetic circuit direction on the contrary.Solved in prior art by this magnetic circuit mode and cause the technical problems such as loudspeaker magnetic flux density is little because space limits, cambered design is used to extend the length of Magnet in the case of limited space, thus improve magnetic density, improve the efficiency of speaker, the magnetic field force that voice coil loudspeaker voice coil is subject to is big, highly sensitive, overall acoustical behavior is good.

In the present embodiment, described Magnet is internal magnetic circuit structure, and described yoke 3 is semicircular structure, and described first Magnet 21 is formed in one with described second Magnet 22, and the center of circle of described magnetic gap is positioned at described yoke 3.
This utility model by being divided into the first Magnet 21 and the second Magnet 22 by Magnet 2, this first Magnet 21 and the second Magnet 22 are loop configuration, it is formed with semicircular magnetic gap between them, uses cambered design to extend the length of Magnet 2 in the case of limited space, magnetic circuit system magnetic flux can be effectively improved, reduce leakage field, improve sensitivity and the sound performance of speaker, there is magnetic flux big, highly sensitive, the advantage that sound performance is good, thus improve the efficiency of speaker.
Embodiment two
Refer to Fig. 2, figure shows a kind of high magnetic flux magnetic circuit of loudspeaker, including the washer 1 combined the most successively, Magnet 2 and yoke 3, described Magnet 2 includes the first Magnet 21 and the second Magnet 22 setting up and down, described first Magnet 21 and described second Magnet 22 are arcuate structure, forming semicircular magnetic gap between described first Magnet 21 and the second Magnet 22, described first Magnet 21 is contrary with the magnetic pole of the second Magnet 22 forms vertical magnetic circuit direction.
In the present embodiment, described Magnet 2 is external magnetic circuit structure, and described yoke 3 is semicircular structure, and described first Magnet 21 is disposed on described washer 1 with described second Magnet 22, and the center of circle of described magnetic gap is positioned at outside described yoke 3.
The principle of the present embodiment is identical with embodiment one, does not repeats them here.
The first Magnet related in this specification and the name of the second Magnet, merely to distinguishing feature, do not represent position relationship therebetween, assemble sequence etc..
These are only preferred embodiment of the present utility model, be not limited to this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
