Groove 61 is isolated, when product ante-chamber water-filling, it is possible to waterproof by vibrating diaphragm, it is to avoid lead-in wire escape groove is leaked and caused product to prevent
Water lost efficacy.
Specifically, Fig. 3 and Fig. 4 respectively illustrates side-looking structure and the section knot of speaker according to embodiments of the present invention
Structure.
Jointly shown in conjunction with Fig. 1 to Fig. 4, the speaker of the embodiment of the present invention, voice coil loudspeaker voice coil 5 includes speech coil framework and is wrapped in sound
Voice coil leads 51 on ring framework, voice coil leads 51 turns on external circuit after inside loudspeakers is drawn, thus realizes raising one's voice
The conducting of device peripheral circuits.Wherein, being provided with two for drawing the lead-in wire escape groove 61 of voice coil leads 51, two lead-in wires are kept away
Groove 61 is allowed to be arranged on the sidewall end face that lower casing 6 contacts with mesochite 4；The position that arranges of lead-in wire escape groove 61 can be according to voice coil loudspeaker voice coil
The extraction location of lead-in wire 51 is adjusted, i.e. lead-in wire escape groove can be arranged on the same sidewall end face of lower casing or relative
On two the sidewall end faces answered.
Wherein, in a lower casing 6 concrete location structure with mesochite 4, can arrange in the four of lower casing 6 corner positions
Four positioning boss 62, in the position of the corresponding positioning boss 62 of mesochite 4, arrange four scarce with dodging of matching of positioning boss 62
Mouthfuls 42, when mesochite 4 assembles with lower casing 6, mesochite 4 is embedded in the upper surface of lower casing 6, by positioning boss 62 with dodge breach 42
Mating reaction, mesochite 4 and lower casing 6 are positioned.
Additionally, in a upper casing 1 concrete location structure with mesochite 4, the end that can contact with upper casing 1 at mesochite 4
Projections/grooves (situation shown in the drawings of location structure is protruding 41) is set on face, at upper casing 1 respective protrusions/groove
Position is provided with groove/land, is coordinated with the groove/land on upper casing 1 by the projections/grooves on mesochite 4, thus to upper casing
1 and mesochite 4 position.Wherein, being arranged on the upper casing 1 projections/grooves on the end face of mesochite 4 side can be ring junction
Structure, or use the multiple projections/grooves structures being disposed on upper casing 1 end face.
It should be noted that the limit in the speaker of the embodiment of the present invention, between mesochite and upper casing and mesochite and lower casing
Position and fixed form, however it is not limited to above-mentioned positioning boss and dodge the fit system of breach, projection and groove, mesochite and upper casing and
Lower casing can also use same way or other similar limited posts, stopper slot to coordinate the multiple spacing fixing sides such as gluing
Formula.
In a specific embodiment of the present invention, vibrating diaphragm 2 farther includes be connected with mesochite 4 and upper casing 1 fixing
The ring portion of the male female structure that fixed part (being positioned at the outermost of vibrating diaphragm) is wholely set with fixed part and be arranged on ring portion
Internal planar portions (being positioned at the penetralia of vibrating diaphragm), reinforcement part 3 is arranged on the planar portions of vibrating diaphragm 2, is mainly used in regulating speaker
Acoustical behavior, for reduce vibrational system oeverall quality, generally vibrating diaphragm planar portions correspondence reinforcement part 3 position arrange go
Material, reinforcement part 3 then covers in this feeding position.Wherein, fixed part is pasted and fixed on upper casing 1 and mesochite 4 two end faces in opposite directions
Between, there is not gap between vibrating diaphragm 2 and upper casing 1 and mesochite 4, it is possible to the water being prevented effectively from ante-chamber enters in speaker
Portion.
Additionally, the speaker of the embodiment of the present invention, also include the magnetic circuit system being housed in upper casing 1, mesochite 4 and lower casing 6；
Wherein, magnetic circuit system include fixing with lower casing 6 be connected conductive magnetic yoke 11, the centring magnet 8 being fixed on conductive magnetic yoke 11 center,
The center washer 7 being correspondingly arranged with centring magnet 8 and limit Magnet 10 around the limit Magnet 10 of centring magnet 8 setting and limit washer
9。
Specifically, magnetic circuit system includes, for fixed magnet the conductive magnetic yoke 11 of revising the magnetic line of force, being pasted and fixed on magnetic conduction
The centring magnet 8 of yoke 11 center and the limit Magnet 10 arranged around centring magnet 8, at centring magnet 8 away from conductive magnetic yoke
The side of 11 has been sticked center washer 7, at limit Magnet 10, the same side of conductive magnetic yoke 11 is provided with limit washer 9；Wherein, center
The hole existed between Magnet 8 and center washer 7 and limit Magnet 10 and limit washer 9 is magnetic gap, and voice coil loudspeaker voice coil 5 is hung between this magnetic
In gap, when the voice coil loudspeaker voice coil 5 being in magnetic field has tone currents to flow through, alternate motion can be produced by an alternation motive force, from
And drive vibrating diaphragm to shake, and then repeatedly promote air and sounding.
In another embodiment of the present invention, limit washer 9 is provided with two, is respectively provided with on each limit washer 9
Flanging and stopper slot, flanging and stopper slot injection is had to be fixed in the sidewall of lower casing 6, it is possible to make limit washer 9 and lower casing 6 in level
All there is package power on direction and vertical direction, it is to avoid washer is peeled off with lower casing 6, can not only guarantee between limit washer and shell
Strong bonded, additionally it is possible to strengthen intensity and the reliability of shell self.
Additionally, also include being moulded in for connecting the shell fragment of the peripheral circuits of speaker on lower casing 6, voice coil leads 51 from
With corresponding shell fragment conducting after drawing in the lead-in wire escape groove 61 of lower casing 6, and then turned on external circuit by shell fragment.
By above-mentioned embodiment it can be seen that the speaker of present invention offer, set between shell and lower casing on a speaker
Putting mesochite, vibrating diaphragm is fixed between mesochite and upper casing, thus the lead-in wire escape groove that will be located on lower casing is isolated with vibrating diaphragm, shakes
Film is difficult to be washed open by water；Meanwhile, it is capable to be prevented effectively from water to enter inside loudspeakers from lead-in wire escape groove, it is possible to increase preventing of product
Aqueous energy, evades the waterproof hidden danger that lead-in wire escape groove causes, and improves stability and the qualification rate of product.
Speaker according to the present invention is described in an illustrative manner above with reference to accompanying drawing.But, those skilled in the art should
Work as understanding, the speaker that the invention described above is proposed, it is also possible to make various on the basis of without departing from present invention
Improve.Therefore, protection scope of the present invention should be determined by the content of appending claims.
