Description
Technical field
The utility model relates to a kind of loudspeaker, and in particular to a kind of double magnet steel racetrack plate speakers.
Background technique
Current plate speaker structure is not only thin but also narrow, and SPL (acoustic pressure) requires height, limits in view of present structure and acoustics,
Plate Microspeaker sound is not loud enough；Generally for SPL (acoustic pressure) requirement for reaching client, can only be added by the way that magnet is increased
Height increases the driving force of loudspeaker, to realize the demand of client, but can make horn mechanism not only high but also big in this way, increase cost；Mesh
Preceding market demand electro-acoustic product will be small in size, and super-thin, sound is big, and at low cost, power is big.Such as current mobile phone, plate electricity
Brain and laptop etc., it is desirable that SPL (acoustic pressure) is very high, at low cost, and power is high.But current horn designs are difficult to meet need
It asks.
Utility model content
In order to solve the above-mentioned technical problem, it is simple to provide a kind of structure for the utility model, small in size, at low cost, can be promoted
Magnetic field strength, and then SPL (acoustic pressure) is promoted, accomplish that SPL (acoustic pressure) is high, power is high, and preferably double magnet steel racetracks are flat for stability
Plate loudspeaker.
The utility model is achieved through the following technical solutions:
A kind of double magnet steel racetrack plate speakers, including bracket, the double course type magnetic circuit system being connect with bracket and vibration
System, double course type magnetic circuit system include outer pole piece, outer steel, interior pole, interior magnet steel and magnetic cover, vibrational system include diaphragm and
Voice coil is provided with outer steel on magnetic cover, and outer steel upper end is provided with outer pole piece, is provided with interior magnet steel in outer steel, on interior magnet steel
End is provided with interior pole, and the gap location between the outer wall of interior magnet steel and the inner wall of outer steel is provided with voice coil, voice coil upper end with set
It is placed in the diaphragm connection of pedestal upper end, pedestal lower end is socketed on outside magnetic cylinder.
Further, the shape of the outer pole piece, outer steel, interior pole, interior magnet steel and magnetic cover is in racetrack.
Further, the shape of the diaphragm and voice coil is in racetrack, and the racetrack that diaphragm is set to the bracket is recessed
In slot.
Further, racetrack groove upper end is provided with block.
The utility model the utility model has the advantages that the utility model loudspeaker it is small in size, it is at low cost, double magnetic steel magnetic circuits can be used promote magnetic
Field intensity, and then the SPL (acoustic pressure) for promoting loudspeaker accomplishes that SPL (acoustic pressure) is high, power when not changing customer facility
Height, stability are more preferable.

Specific embodiment
As shown in Figures 1 to 4, a kind of double magnet steel racetrack plate speakers, including bracket 1, the double course type being connect with bracket 1
Magnetic circuit system and vibrational system, vibrational system include diaphragm 2 and voice coil 3, and double course type magnetic circuit system includes outer pole piece 4, outer magnetic
Steel 5, interior pole 6, interior magnet steel 7 and magnetic cover 8 are provided with outer steel 5 on magnetic cover 8, and 5 upper end of outer steel is provided with outer pole piece 4, outer magnetic
Interior magnet steel 7 is provided in steel 5, interior 7 upper end of magnet steel is provided with interior pole 6, between the outer wall of interior magnet steel 7 and the inner wall of outer steel 5
Gap location be provided with voice coil 3,3 upper end of voice coil is connect with the diaphragm 2 for being set to 1 upper end of bracket, and 1 lower end of bracket is socketed on magnetic cylinder
Outside.Double course type magnetic circuit system is for driving vibrational system vibration sounding.
In the present embodiment, outer pole piece 4, outer steel 5, interior pole 6, the shape of interior magnet steel 7 and magnetic cover 8 are in racetrack.
In the present embodiment, the shape of diaphragm 2 and voice coil 3 is in racetrack, and diaphragm 2 is set to the racetrack groove of bracket 1
It is interior.Racetrack groove upper end is provided with block 11.
The utility model includes bracket 1, and bracket 1 is followed by magnetic cover 8, and interior magnet steel 7, interior pole 6 are fixed in magnetic cover 8, interior
The surrounding of magnet steel 7 and interior pole 6 is voice coil 3, and voice coil 3 is connected with the diaphragm 2 above interior pole 6, also encloses in the outer ring of voice coil 3
There are outer steel 5 and outer pole piece 4, outer steel 5 and outer pole piece 4 are fixed in magnetic cover 8.
