Solve voice coil loudspeaker voice coil to work under big displacement the technical scheme of this technical problem of easily breaking, to improve Microspeaker
Reliability and service life so that it can adapt to the development trend of Microspeaker product.
Utility model content
For disadvantages described above, first technical problem to be solved in the utility model is to provide a kind of voice coil loudspeaker voice coil,
This voice coil loudspeaker voice coil reliability is high, its voice coil leads not easy fracture, it is possible to adapt to work under big displacement.
Based on same inventive concept, second technical problem to be solved in the utility model is to provide one
Microspeaker, this Microspeaker reliability is high, voice coil leads not easy fracture, and service life is long, it is possible to
Adapt to the development trend of Microspeaker product.
For solving above-mentioned first technical problem, the technical solution of the utility model is:
A kind of voice coil loudspeaker voice coil, is formed by voice coil line coiling, and the coiling number of plies of described voice coil line is even level, is positioned at
The initial outlet position of the described voice coil line of internal layer and the outlet position, end being positioned at outermost described voice coil line
Between there is difference in height, described difference in height is less than 1.5 times of described voice coil line line footpath.
As a kind of embodiment, described difference in height is 1.5 times of described voice coil line line footpath.
As another embodiment, described difference in height is 0.5 times of described voice coil line line footpath.
For solving above-mentioned second technical problem, the technical solution of the utility model is:
A kind of Microspeaker, including vibrational system and magnetic circuit system, described vibrational system includes being combined in one
The vibrating diaphragm risen and voice coil loudspeaker voice coil, described voice coil loudspeaker voice coil is above-mentioned voice coil loudspeaker voice coil.
After have employed technique scheme, the beneficial effects of the utility model are:
Owing to this utility model voice coil loudspeaker voice coil is formed by voice coil line coiling, and be positioned at innermost layer voice coil line initial go out
Line position and have difference in height between the outlet position, end of outermost voice coil line, difference in height is less than sound
1.5 times of astragal line footpath.From the standpoint of reliability breaks, initial outlet position and outlet position, end
Difference in height is the least, and the length of end leads can be the biggest, it is possible to effective reduction outlet subjected to stress, because of
It is bad that this can alleviate that end leads breaks because of tired to a great extent, thus effectively reduces sound
Circle lead-in wire works under big displacement and the probability of broken string occurs, and improves the reliability of voice coil loudspeaker voice coil, it is possible to adapt to greatly
Work under displacement.Initiate outlet position little with the difference in height of outlet position, end simultaneously, also help in outlet
Place carries out strengthening design, can further reduce outlet subjected to stress, reduces voice coil leads further and breaks
The probability split.
Owing to the voice coil loudspeaker voice coil of this utility model Microspeaker is above-mentioned voice coil loudspeaker voice coil, thus reliability is high, voice coil leads
Being difficult to broken string, service life is long, it is possible to adapt to the development trend of Microspeaker product.
In sum, this utility model voice coil loudspeaker voice coil and be provided with the Microspeaker of this voice coil loudspeaker voice coil and solve in prior art
Voice coil loudspeaker voice coil works the technical problem of easy broken string under big displacement, this utility model voice coil loudspeaker voice coil and be provided with the miniature of this voice coil loudspeaker voice coil
The voice coil leads of speaker not easy fracture, reliability is high, and service life is long, it is possible to adapts to Microspeaker and produces
The development trend of product.
