A kind of loudspeaker provided by the invention referring to Fig. 1, including shell 1 and is located in shell 1 in some embodiments
Vibrational system.The vibrational system includes vibrating diaphragm component 2 and voice coil 3.Referring to figs. 2 and 3, the voice coil 3 uses enameled wire
31 are coiled to form.
Further, it when coiling enameled wire 31, can coil in a heated state, so that the insulation of adjacent enameled wire
Layer melts connection in a heated state, generates self-adhesion；Or it is also possible to the gluing on enameled wire, so that adjacent enameled wire is logical
Cross colloid bonding；So that the voice coil 3 being finally made of enameled wire is capable of forming the structure of relative securement.
Referring to figs. 2 and 3, along the axis between 3 both ends of voice coil, the voice coil 3 divides for voice coil top 32 and sound
Enclose lower part 33.Voice coil 3 in the radial direction, the voice coil top 32 be single layer enameled wire 31, the voice coil lower part 33 is at least
Two layers of enameled wire 31.Voice coil lower part 33 is due to the enameled wire 31 with multilayer, so that about 31 enameled wire and between layers
Adjacent enameled wire 31 is all had, so that structure is more firm；And voice coil top 32 is single layer enameled wire 31, lacking layers and layer it
Between fixation so that 32 structural rigidity of voice coil top is weaker；But voice coil top 32 increases by 31 number of plies of enameled wire and then can greatly increase
The weight of summation tone circle 3 influences the acoustical behavior of loudspeaker.
Referring to figs. 2 and 3, in radial directions, the voice coil top 32 is thinner than voice coil lower part 33, the voice coil top 32
It is thinner than on the side of voice coil lower part 33 and is provided with reinforcement paper 34, the reinforcement paper connects between the voice coil both upper ends thereof and both ends
Enameled wire 31.By the setting of reinforcement paper 34, the multi-turn enameled wire 31 on voice coil top 32 can be connected in side, in stress
When stress as a whole, improve the rigidity on voice coil top 32, the active force of vibration be dispersed on reinforcement paper, voice coil is prevented
The deformation of top 32 or loose wire, improve the reliability of voice coil 3.
The reinforcement paper 34 can be the patch in the insulating layer thermal connection of the enameled wire 31 on voice coil top 32 and lead on the outside
The self-adhesion for crossing insulating layer is Nian Jie with insulating layer；It is also possible to be bonded on voice coil by mode pre-gelatinized on voice coil top 32
The side in portion 32；Or be also possible to reinforcement paper and carry gum, voice coil top 32 is bonded in by gum；The application to this not
Limitation.
The reinforcement paper 34 can be brown paper, be also possible to Xuanhua paper, be also possible to the higher papery of other toughness
Material, the application are not intended to limit this.
The reinforcement paper 34 can surround the voice coil top 32 along the circumferential direction of voice coil 3, improve voice coil top 32
Rigidity.It is also possible to several reinforcement paper 34 to be arranged along the circumferential direction interval of voice coil 3, the application is not intended to limit this.
It can be as shown in Figures 2 and 3, voice coil lower part 33 is located at than the coast of paint envelope curve 31 that voice coil top 32 has more
3 outside of voice coil, the upper voice coil top 32 is thinner than the voice coil lower part 33 on the outside of voice coil 3, and the reinforcement paper 34 is arranged in sound
Enclose the outside on top 32.In some other embodiments, it is also possible to voice coil lower part 33 to have more at least than voice coil top 32
Coast of paint envelope curve 31 is located at 3 inside of voice coil, then the reinforcement paper 34 can also be located at the inside on circle top 32.
In radial directions, the thickness for being provided with the voice coil top 32 of the reinforcement paper 34 is less than or equal under the voice coil
The thickness in portion 33.As shown in Figure 3, the voice coil lower part 33 is located at voice coil than the coast of paint envelope curve 31 that voice coil top 32 has more
3 outsides, the wall thickness for being provided with the voice coil top 32 of the reinforcement paper 34 is also not more than the voice coil lower part 33, in proof strength
Meanwhile increase of the reduction to 3 volume of voice coil.On the other hand, the density of paper material is generally also lower than the density of metal, then setting
Reinforcement paper 34 is set relative to 31 number of plies of enameled wire is increased, reinforcement paper 34 is also smaller to the weight increase of voice coil 3.
Referring to Fig. 1, the loudspeaker further includes having magnetic circuit system, the voice coil top 32 of the voice coil 3 and the vibrating diaphragm group
Part 2 connects, and voice coil lower part 33 is deep into the magnetic gap of magnetic circuit system, and after voice coil 3 is powered, voice coil lower part 33 is under magnetic fields
Active force is generated, generates vibration as frequency changes, so that vibrating diaphragm component 2 be driven to vibrate, connection vibrating diaphragm is played on voice coil top 32
The effect of component 2 and voice coil lower part 33.
The section of the voice coil 3 in the axial direction can be circle, or rectangle, concrete shape those skilled in the art
Member can be configured according to magnetic circuit system, and the application is not intended to limit this.
The voice coil 3 is connected on the shell 1 by the vibrating diaphragm component 2, right by driving vibrating diaphragm component 2 to vibrate
It makes a sound outside.
In some embodiments, referring to Fig. 1, the magnetic circuit system may include U iron 4, the center that 4 centre of U iron is arranged in
Washer 6 above magnet 5, centrally disposed magnet 5.Centring magnet 5 described in 4 clamping of the washer 6 and U iron.The washer 6 is not
Higher than the side wall of U iron 4, magnetic gap is formed between washer 6 and the side wall of U iron 4, the magnetic gap is protruded into the voice coil lower part 33
It is interior.In some other embodiments, the magnetic circuit system can also be other forms, such as three magnet magnetic circuits, five magnet
Magnetic circuit etc., the application is not intended to limit this.
Although some specific embodiments of the invention are described in detail by example, the skill of this field
Art personnel it should be understood that above example merely to being illustrated, the range being not intended to be limiting of the invention.The skill of this field
Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above embodiments.This hair
