Description
Technical field
The utility model belongs to loudspeaker accessory technical field, more particularly, to a kind of loudspeaker magnet steel.
Background technique
Loudspeaker is also known as " loudspeaker ".It is a kind of very common electro-acoustic transducer device, it can in the electronic circuit spoken
See it.Magnet steel is an important component in loudspeaker, and effect is magnetic property by homeostasis, the electric current of variation lead into
When loudspeaker, magnet becomes electromagnet, and current direction constantly changes, and electromagnet is since " electrified wire stress in magnetic field is transported
It is dynamic " and also ceaselessly move back and forth, drive cone also to shake back and forth, to make loudspeaker public address, with the stable distortion factor and
Acoustical quality, existing similar product generally use circle magnet steel made of general permanent magnetism material, not due to the permanent magnetism material quality
Good, unstable so as to cause the distortion factor, acoustical quality is also affected significantly, and prolonged use, inductance coil fever
Also it will affect acoustical quality.
Summary of the invention
The utility model mainly solves technical problem present in the above-mentioned prior art, provides a kind of loudspeaker magnet steel.
Above technical problems of the utility model are mainly solved by the following technical scheme: a kind of loudspeaker magnetic
Steel, including connection frame, the connection frame is T-shaped, and the center is equipped with connecting hole, is equipped with screw thread, the company in the connecting hole
The outside for connecing frame is equipped with two piece of first magnet, and first magnet is in semi-circular, and the polarity of two piece of first magnet opposing sides
Identical, the lower section of the connection frame is equipped with the second magnet, second magnet in a ring, and the top surface of second magnet and two pieces
The bottom surface polarity of first magnet is identical.
Preferably, the connection frame is constituted using aluminium alloy production.
Preferably, first magnet and the second magnet are all made of high performance Nd-Fe-B permanent magnet material production and constitute.
Preferably, several symmetrical circular holes are equipped on first magnet and the second magnet.
Preferably, the joint face of both the connection frame and the first magnet vertical direction is in mutually matched type tooth, favorably
In the installation stability for increasing the first magnet and connection frame, while increasing the heat dissipation area of the first magnet.
The utility model has the advantages that the utility model uses the side of two piece of first magnet and connection frame split
Formula, structure is simple, easy for installation, while being beneficial to the heat dissipation of the first magnet；The second magnetic being inversely bonded is equipped with below connection frame
Body improves magnetic gap flux density, to improve loudspeaker sensitivity, is beneficial to intermediate frequency energy and the low frequency control of loudspeaker
Power；Connecting hole at connection frame center is equipped with screw thread, convenient for connecting the other component of loudspeaker, improves space utilization rate；Even
The joint face of frame and the first magnet is connect in mutually matched type tooth, increases the heat dissipation area of the first magnet, magnet is equipped with circle
Hole, while connection frame uses heat sink material, makes the inductance coil of loudspeaker be easier to radiate, improves power termination ability, subtract
Few loss to work long hours to powerful loudspeaker also can guarantee using effect, sound quality even if continuous use for a long time
Effect will not be distorted；First magnet and the second magnet use high performance Nd-Fe-B permanent magnet material, improve loudspeaker distortions degree
And stability, service life also greatly improve.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model；
Fig. 2 is a kind of overlooking structure diagram of the utility model.
In figure: 1, connection frame；2, connecting hole；3, the first magnet；4, the second magnet；5, circular hole.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of loudspeaker magnet steel, as Figure 1-Figure 2, including connection frame, the connection frame is T-shaped, center
Place is equipped with connecting hole, and screw thread is equipped in the connecting hole, and the outside of the connection frame is equipped with two piece of first magnet, first magnetic
Body is in semi-circular, and the polarity of two piece of first magnet opposing sides is identical, and the lower section of the connection frame is equipped with the second magnet, described
In a ring, and the top surface of second of magnet is identical with the bottom surface polarity of two piece of first magnet for second magnet.
The connection frame is constituted using aluminium alloy production.
First magnet and the second magnet are all made of high performance Nd-Fe-B permanent magnet material production and constitute.
Several symmetrical circular holes are equipped on first magnet and the second magnet.
The joint face of both the connection frame and the first magnet vertical direction is in mutually matched type tooth, is conducive to increase by the
The installation stability of one magnet and connection frame, while increasing the heat dissipation area of the first magnet.
When work, magnet is connect by adhesive with connection frame split, then loudspeaking is connected by the connecting hole of connection frame
The other component of device rationally utilizes space, while the circular hole in the design and magnet of two pieces of first magnets of formula helps to radiate, and increases
Add the second magnet, enhanced the magnetism of loudspeaker, guarantees acoustical quality.
Finally it is pointed out that above embodiments are only the more representational examples of the utility model.Obviously, this is practical new
Type is not limited to the above embodiments, and acceptable there are many deformations.All foundation the technical essence of the utility model are to above embodiments
Made any simple modification, equivalent change and modification are considered as belonging to the protection scope of the utility model.
