The hanging scheme of the common lead of loudspeaker/receiver at present：The symmetrical outlet of lead long axis or short axle side, another
Side is welded, and when loudspeaker access signal, and vibrational system starts vibration, voice coil leads curved arc part stress is larger, and is provided suitable
Property be pliable several times or more than ten times of vibrating diaphragm, the balance vibration of vibrating diaphragm is affected greatly, vibrating diaphragm rolling is caused to be shaken, one end amplitude
Greatly, one end amplitude is small, and vibrating diaphragm is softer in addition, and magnetic circuit assembling tolerance is slightly larger, will the wiping of outlet voice coil touch magnetic circuit and lead to harmonic distortion
Outlet spike, vibrational system stress is disorderly caused by voice coil wiping is touched during reliability of service life, and voice coil bottoming is caused to break, and product loses
Effect.
Utility model content

It is further improved:
Frame is further included, the first voice coil and the second voice coil combine to form first assembly with frame.
It is further improved:
Vibrating diaphragm and top dome are further included, vibrating diaphragm and top dome are bonded to form the second component.
It is further improved:
First assembly and the second component are bonded together.
It is further improved:
First voice coil and the second hanging outlet of voice coil bilateral, the vibration for improving single voice coil leads hanging structure is uneven,
Reduce mobile phone speaker/undesirable risk of receiver noise.
It is further improved:
First voice coil and the second voice coil are connected in series with, and are remained to work on after single voice-coil open, are reduced mobile phone and raise one's voice
Device/undesirable the risk of receiver tone-off failure.
It is further improved:
It the position of first voice coil and the second voice coil outlet can be from long axis or short axle outlet.
The utility model uses above-mentioned technical proposal, has the advantage that：
1. the hanging outlet of double voice coil bilateral, the vibration for improving single voice coil leads hanging structure is uneven, reduces mobile phone
The undesirable risk of loudspeaker/receiver noise；
2. double voice coil is connected in series with, remain to work on after single voice-coil open, reduce mobile phone speaker/receiver without
The undesirable risk of sound failure；The vibration for solving current mobile phone speaker/receiver vibrational system is uneven, promotes properties of product
Yield, stability and service life；The utility model improves unilateral voice coil and goes wrong, and is changed to symmetrical outlet, it is curved to improve lead
Arc influences the unbalance vibration of vibrational system.
The utility model is described further below in conjunction with the accompanying drawings.

Specific embodiment
Embodiment, as shown in attached drawing 1, attached drawing 2, attached drawing 3 and attached drawing 4, a kind of speaker unit for improving vibration, including the
One voice coil 3 and the second voice coil 4,3 and second voice coil 4 of the first voice coil connect, and the homonymy of the first voice coil 3 and the second voice coil 4 draws
Line is welded on two pads.
First voice coil, 3 and second voice coil 4 bonds together vertically.
The utility model further includes frame 5, and the first voice coil 3 and the second voice coil 4 combine to form first assembly 7 with frame 5.
The utility model further includes vibrating diaphragm 2 and top dome 1, and vibrating diaphragm 2 and the bonding of top dome 1 form the second component 8.
The utility model further includes 7 and second component 8 of first assembly and is bonded together.
The utility model further includes the first voice coil 3 and the hanging outlet of 4 bilateral of the second voice coil；It is hanging to improve single voice coil leads
The vibration of structure is uneven, reduces mobile phone speaker and the undesirable risk of receiver noise.
The utility model further includes the first voice coil 3 and the second voice coil 4 is connected in series with；It remains to continue work after single voice-coil open
Make, reduce mobile phone speaker/undesirable risk of receiver tone-off failure；The position of 4 outlet of first voice coil 3 and the second voice coil can
