The lateral surface of the shell is equipped with decoration, and the medial surface of the decoration is fixed with decoration magnet, the dress
Gadget magnet is opposite with the opposite face magnetic pole of the shell magnet.
According to the utility model of above scheme, which is characterized in that the inner casing is fastened and connected with the shell.
According to the utility model of above scheme, which is characterized in that the medial surface of the shell is outer equipped with what is be recessed outward
Shell groove, the shell magnet are fixed in the outer casing groove.
According to the utility model of above scheme, which is characterized in that the lateral surface of the shell is consolidated equipped with what is outwardly protruded
Determine convex block, the medial surface of the decoration is equipped with the first decoration groove being recessed outward, the first decoration groove and institute
Fixed convex block is stated to be cooperatively connected.
According to the utility model of above scheme, which is characterized in that the medial surface of the decoration is equipped with to be recessed outward
Second decoration groove, the decoration magnet are fixed in the second decoration groove.
According to the utility model of above scheme, the beneficial effect is that, the utility model passes through the anti-drive of internal structure
It is dynamic, so that the intensity amplification 15% of loudspeaker, saves the application of extra component, reduce the weight of entire earphone, structure is more
Step up to gather；The utility model is detachably connected by decoration, realizes the replacement at any time of decoration, and it is more convenient to operate,
Overall beautiful degree is higher.

Specific embodiment
With reference to the accompanying drawing and the utility model is further described in embodiment:
As shown in Figure 1, a kind of moving-magnetic type bone conduction earphone of diamagnetism amplification driving, including two headset main bodies 2, two
It is connected between headset main body 2 by rack 1.
As Figure 2-3, headset main body 2 includes inner casing 5 and shell 7, it is preferred that inner casing 5 is fastened and connected with shell 7.It is interior
Dynamic magnetic speaker 4 is equipped in the space that shell 5 and shell 7 surround.
The medial surface of inner casing 5 is equipped with skin conductance piece 3, and the medial surface of shell 7 is fixed with shell magnet 6, shell magnet 6 with
Interstitial spaces are equipped between dynamic magnetic speaker 4, and shell magnet 6 is identical as the opposite face magnetic pole of dynamic magnetic speaker 4.Specifically,
The medial surface of shell 7 is equipped with the outer casing groove 10 being recessed outward, and shell magnet 6 is fixed in outer casing groove 10, recessed by shell
Slot 10 stores shell magnet 6, not only can guarantee being bonded for shell magnet 6, but also make the smooth interior surfaces of shell 7, while again
It will not influence the magnetic force between shell magnet 6 and dynamic magnetic speaker 4.
During the diamagnetism driving of dynamic magnetic speaker 4, the opposite face magnetic pole phase of magnetic speaker 4 and shell magnet 6 is moved
Together, the two is mutually exclusive；The diamagnetic effect of shell magnet 6 pushes dynamic magnetic speaker 4, its intensity amplification is made to reach 15%.
On the other hand, the lateral surface of shell 7 is equipped with the fixation convex block 11 outwardly protruded, is equipped with decoration 9 on the outside of shell 7,
The medial surface of decoration 9 is equipped with the first decoration groove 12 being recessed outward, and the first decoration groove 12 is matched with fixed convex block 11
Close connection.It is cooperated by the first decoration groove 12 and fixed convex block 11, decoration 9 is positioned, guarantee decoration 9
It not can rotate.
