Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, showing coaxial horn provided by the embodiment of the utility model, include at least: there are central axes 9
T iron 1, the first magnetic structure and the second magnetic structure.T iron 1 has an iron prop 11 along 9 direction of central axes, on iron prop 11
It is provided with horn bulb 2.First magnetic structure includes the first magnet 31, the first voice coil 32, the first sound basin 33 and the first bullet wave
34, the first magnet 31 in a ring and is sheathed on iron prop 11, in general, iron prop 11 can be made cylindric, and be allowed
One magnet 31 is in circular ring shape, and magnetic gap 4 is suitably formed between the first magnet 31 and iron prop 11, and the first voice coil 32 is suitable in magnetic gap 4
Moved along 9 direction of central axes, the first sound basin 33 is connect with the first voice coil 32, first play wave 34 be suitable for the first voice coil 32 and
First sound basin 33 is supported on horn bulb 2.Second magnetic structure include the second magnet 51, the second voice coil 52, the second sound basin 53,
Second plays wave 54, the ferromagnetic unit 55 being coaxially disposed with iron prop 11 and for the supporting element by the support of ferromagnetic unit 55 inside the shell；
Second magnet 51 in a ring and is arranged and on ferromagnetic unit 55, ferromagnetic unit 55 can equally be made cylindric, and allows the second magnetic
Iron 51 is in circular ring shape, and magnetic gap 4 is suitably formed between the second magnet 51 and ferromagnetic unit 55, and the second voice coil 52 is suitable for the edge in magnetic gap 4
Central axes 9 move, and the second sound basin 53 is connect with the second voice coil 52, and second, which plays wave 54, is suitable for the second voice coil 52 and the second sound
Basin 53 is supported on horn bulb 2.
By the way that the first magnetic structure and the second magnetic structure, and the first voice coil 32 in the first magnetic structure is arranged
Suitable for being moved in the magnetic gap 4 that is formed between the first magnet 31 and iron prop 11 along 9 direction of central axes, in the second magnetic structure
It is moved in the magnetic gap 4 that two voice coils 52 are suitable for being formed between the second magnet 51 and ferromagnetic unit 55 along 9 direction of central axes, and ferromagnetic unit
55 are coaxially disposed with iron prop 11 again, i.e. the first voice coil 32 substantially moves on the same axis with the second voice coil 52, so first
The effect of voice coil 32 and the second voice coil 52 can reach preferable sound quality very close to point sound source.Additionally, due to the first voice coil 32
The magnetic circuit of the first magnet 31 is used, the second voice coil 52 uses the magnetic circuit of the second magnet 51, i.e. two voice coils use
Magnetic circuit is different, so will not generate interference, Ke Yibao between two voice coils in the use process of the utility model coaxial horn
The audio that card plays is stablized.
Preferably embodiment, supporting element include support bar 56 and are supported inside the shell by support bar 56
Support platform 57, support platform 57 and iron prop 11 are coaxially disposed, and ferromagnetic unit 55 is placed in support platform 57.I.e. particular by upper
The set-up mode stated allows this part of iron and iron prop 11 to be coaxially disposed.
Preferably, coaxial horn further includes gasket 6, and gasket 6 is in shape, and the first magnet 31 is between T iron 1 and gasket 6, pad
Piece 6 is locked in T iron 1 by bolt 7, and horn bulb 2 is connect with gasket 6.Wherein gasket 6 plays the work of the first magnet 31 of protection
With being locked at the first magnet 31 is also to be realized in T iron 1 by gasket 6, and can extend the first magnet 31 in this way uses the longevity
Life, in addition horn bulb 2 is suitable for what gasket 6 was connected, so will be outer whether through the mode of screw locking or glue bonding
Shell is fixed, this will not all directly influence the first magnet 31, for example, when being locked by screw, without being opened on the first magnet 31
If screw hole, the possibility of the damage of the first magnet 31 can be reduced in this way.
Preferably, the first bullet wave 34 passes through extensible member 8 and cage connection, the telescopic direction of extensible member 8 and the first sound basin 33
The direction of motion it is consistent.By taking the placing direction of coaxial horn shown in FIG. 1 as an example, because being affected by gravity, the first sound basin
33 move downward be can very easily, and while moving upwards, just needs more can just move upwards energetically, will result in first in this way
The non-linear distortion of 33 piston motion of sound basin, so that low frequency characteristic is poor, and the telescopic direction of extensible member 8 and the first sound basin 33
The direction of motion is consistent, it is possible to which eliminating gravity bring by extensible member 8 influences, so as to improve the utility model coaxial horn
Low frequency characteristic.Specifically, first wave 34 is played in a ring, first plays 34 outer edge of wave by extensible member 8 and cage connection, and first
34 inward flange of wave is played to connect with the first voice coil 32.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
