In gap, the magnetic line of force that magnetic circuit system is formed passes through voice coil 5.Wherein voice coil 5 is usually entwined by conductive wire, such as copper clad aluminum
Line is alternation letter due to being connected in voice coil by Ampere force in the magnetic field that magnetic circuit system is formed after voice coil connects electric signal
Number, the size and Orientation of suffered Ampere force corresponds to signal intensity;It is acted on by Ampere force, voice coil 5 shakes up and down in magnetic gap
It is dynamic, since voice coil 5 and vibrating diaphragm 4 are that secure bond is integrated, drive vibrating diaphragm 4 to vibrate by the vibration of voice coil 5, to generation sound
Sound.
As can be seen that loudspeaker monomer 1 further includes monomer shell 15, monomer shell 15, frame 8 and mould from Fig. 1 and Fig. 4
Space between group shell upper casing 2 and module lower casing 3 forms the rear operatic tunes 13, which is closed space.
Fig. 5 a are the partial enlarged view of Fig. 4, and in conjunction with Fig. 5 a, Fig. 2 and Fig. 4, metal screen layer 11 is to be plated in module casing side
The metal layer of wall outer surface, specifically, metal screen layer 11 are plated in the side wall inner surfaces pair that module upper casing 2 is not contacted with antenna 10
On the wall outer surface answered, it is also plated in 2 bottom wall inner surface of module upper casing not in contact on the corresponding bottom wall outer surface in 10 part of antenna,
And the outer side wall surface of module lower casing 3, that is, in Fig. 4 on module upper casing 2 and the wall outer surface in the left side of model lower casing 3 and
On the bottom wall outer surface of module upper casing 2.
Fig. 5 a are exaggerated module upper casing 2 and module lower casing 3 be coated with metal screen layer 11 side wall junction, from Fig. 5 a
As can be seen that module upper casing 2 and the shape that module lower casing 3 is characteristic, on the outside of the edge of module upper casing 2 and module lower casing 3
For arc angling, after fitting together module upper casing 2 and module lower casing 3, two arc anglings are formed in 2 He of module upper casing
The junction of module lower casing 3 forms groove, and the groove of a position is merely illustrated in Fig. 5 a, in conjunction with Fig. 1, the groove be not
A circle in certain position of junction but around junction is set, the junction of module upper casing 2 and module lower casing 3 is set
Count into groove be in order to store solder(ing) paste, since solder(ing) paste does not cure at normal temperatures, existing module upper casing and module lower casing
It is not chamfer shape on the outside of edge, it is natural recessed there is no being made of chamfering in the junction of module upper casing and module lower casing
Slot, no groove can not just store the solder(ing) paste under room temperature, and solder(ing) paste can flow to everywhere, and therefore, the embodiment of the present invention is designed to
It is the module upper casing and module lower casing of arc angling shape on the outside of edge.
It should be noted that 200 DEG C or so of high temperature can be such that solder(ing) paste melts, the solder(ing) paste after thawing can be consolidated at normal temperatures
Chemical conversion scolding tin 14 (being the scolding tin formed after solder(ing) paste cures in Fig. 4, Fig. 5 a and Fig. 5 b).
On the other hand, it is to distinguish that scolding tin 14 is applied in the junction of module upper casing 2 and module lower casing 3 formation groove
The metal screen layer 11 for being plated in 3 outer surface of 2 outer surface of module upper casing and module lower casing links together, and forms the screen of an entirety
Cover cover, moreover it is possible to play the role of sealing module upper casing 2 and module lower casing 3, the embodiment of the present invention is made by solder horn in groove
Solder(ing) paste melts (200 DEG C or so), and solder(ing) paste is solidified into scolding tin 14 at normal temperatures, and then will be plated under module upper casing 2 and module
The metal screen layer 11 of the wall outer surface of shell 3 is connected to, and is formed a shielding case, can be prevented outer signals potato masher antenna 10,
Scolding tin 14 can also play the role of sealing, and the space inside module casing is allowed to form the rear operatic tunes 13.
In addition, be provided with welding bar (not shown) in the edge of module upper casing 2 and/or module lower casing 3, welding bar with
Module upper casing 2 and/or module lower casing 3 are integrally formed, and the embodiment of the present invention melts welding bar by ultrasonic bonding to be made on module
Shell 2 and module lower casing 3 are combined together, but other manner can also be used to melt welding bar, make module upper casing 2 and module lower casing
3 are combined together.
Fig. 5 b are another partial enlarged view of Fig. 4, in conjunction with Fig. 5 b, Fig. 2 and Fig. 4, due in the plating of antenna 10 in Fig. 4 module
In side wall inner surfaces on the right side of shell, so without plating metal screen layer 11 on wall outer surface in Fig. 4 on the right side of module upper casing.
From in Fig. 5 b it can also be seen that antenna 10 be plated in the side wall inner surfaces of module upper casing 2, module upper casing 2 and module
It is coated with scolding tin 14 in the groove that the junction of lower casing 3 is formed.
The raw material that above-mentioned metal screen layer 11 preferably uses can preferably protect antenna 10, prevent its oxygen for gold, gold
Change, but raw material of other metals as metal screen layer 11 can also be used, and metal screen layer 11 is arranged in module casing
Outside is that the other structures of loud speaker module internal contact generation short circuit with metal screen layer 11 in order to prevent.
It is above-mentioned to be described in detail by loud speaker module provided in an embodiment of the present invention, since antenna being plated in module casing
Side can prevent antenna from touching other accessories, reduce the loss of antenna, moreover it is possible to prevent antenna from being aoxidized, while in module shell
Metal screen layer is arranged in the part that the outside of body is not contacted with antenna, can shield interference of the outer signals to antenna well.
It is described in an illustrative manner above with reference to attached drawing according to loud speaker module proposed by the present invention.But this field
It will be appreciated by the skilled person that for the loud speaker module that aforementioned present invention is proposed, the content of present invention can also not departed from
On the basis of various improvement are made to realization details therein.Therefore, protection scope of the present invention should be by the attached claims
The content of book determines.
