Fig. 3 shows according to the back side of the structural entity of the loud speaker module of the embodiment of the present invention.
As can be seen from Figure 3, loud speaker module comprises two loudspeaker monomers 1, is separately positioned on the both sides of module upper casing 2, and one end of cable line 12 is connected with loud speaker module external circuit.
Fig. 4 is the cutaway view along A-A line in Fig. 3, in conjunction with Fig. 1 and Fig. 4, and loudspeaker monomer 1 involving vibrations system and magnetic circuit system, vibrational system comprises vibrating diaphragm 4 and is incorporated into the voice coil loudspeaker voice coil 5 of vibrating diaphragm 4 one sides; Magnetic circuit system comprises washer 6, magnet 7 and the basin frame 8 of combination successively, and the gap between the lateral surface of washer 6, magnet 7 and basin frame 8 sidewalls forms magnetic gap, and voice coil loudspeaker voice coil 5 is contained in magnetic gap, and the magnetic line of force that magnetic circuit system forms is through voice coil loudspeaker voice coil 5.Wherein voice coil loudspeaker voice coil 5 is entwined by conductive wire conventionally, and as copper-clad aluminum conductor, voice coil loudspeaker voice coil is connected after the signal of telecommunication, in the magnetic field forming, is subject to Ampere force at magnetic circuit system, is alternating signal due to what connect in voice coil loudspeaker voice coil, and the size and Orientation respective signal of suffered Ampere force changes; Be subject to the effect of Ampere force, voice coil loudspeaker voice coil 5 up-down vibration in magnetic gap, because voice coil loudspeaker voice coil 5 is that secure bond is integrated with vibrating diaphragm 4, drives vibrating diaphragm 4 to vibrate by the vibration of voice coil loudspeaker voice coil 5, thereby produces sound.
From Fig. 1 and Fig. 4, can find out, loudspeaker monomer 1 also comprises monomer shell 15, and the space between monomer shell 15, basin frame 8 and module shell upper casing 2 and module lower casing 3 forms the rear operatic tunes 13, the space that this rear operatic tunes 13 is sealing.
Fig. 5 a is the partial enlarged drawing of Fig. 4, in conjunction with Fig. 5 a, Fig. 2 and Fig. 4, metal screen layer 11 is for being plated in the metal level of module casing sidewall outer surface, particularly, metal screen layer 11 is plated on sidewall outer surface corresponding to side wall inner surfaces that module upper casing 2 do not contact with antenna 10, also be plated in module upper casing 2 diapire inner surfaces not on diapire outer surface corresponding to Contact antenna 10 parts, and the outer side wall surface of module lower casing 3, namely in Fig. 4 on the sidewall outer surface in module upper casing 2 and model lower casing 3 left sides and on the diapire outer surface of module upper casing 2.
Fig. 5 a has amplified module upper casing 2 and module lower casing 3 and has been coated with the junction of the sidewall of metal screen layer 11, from Fig. 5 a, can find out, the shape that module upper casing 2 and module lower casing 3 are characteristic, outside, edge at module upper casing 2 and module lower casing 3 is arc angling, after module upper casing 2 and module lower casing 3 are fitted together, two arc anglings are formed on the junction formation groove of module upper casing 2 and module lower casing 3, in Fig. 5 a, only show the groove of a position, in conjunction with Fig. 1, this groove be not be arranged on junction position, certain but around a circle of junction, it is in order to store solder(ing) paste that the junction of module upper casing 2 and module lower casing 3 is designed to groove, because solder(ing) paste does not solidify at normal temperatures, the outside, edge of existing module upper casing and module lower casing is not chamfer shape, there is not in the junction of module upper casing and module lower casing the groove being formed by chamfering in nature, do not have groove just cannot store the solder(ing) paste under normal temperature, solder(ing) paste can flow to everywhere, therefore, the embodiment of the present invention is designed to module upper casing and the module lower casing that outside, edge is arc angling shape.
It should be noted that, the high temperature of 200 DEG C of left and right can make solder(ing) paste melt, and the solder(ing) paste after thawing is curable one-tenth scolding tin 14 (solidifying the scolding tin of rear formation in Fig. 4, Fig. 5 a and Fig. 5 b for solder(ing) paste) at normal temperatures.
On the other hand, forming in the junction of module upper casing 2 and module lower casing 3 and being coated with scolding tin 14 in groove is for the metal screen layer 11 that is plated in respectively module upper casing 2 outer surfaces and module lower casing 3 outer surfaces is linked together, form an overall radome, can also play the effect of sealing module upper casing 2 and module lower casing 3, the embodiment of the present invention makes the solder(ing) paste in groove melt (200 DEG C of left and right) by solder horn, solder(ing) paste is solidified into scolding tin 14 at normal temperatures, and then the metal screen layer 11 of the sidewall outer surface that is plated in module upper casing 2 and module lower casing 3 is communicated with, form a radome, can prevent outer signals potato masher antenna 10, scolding tin 14 can also play the effect of sealing, allow the space of module casing inside form the rear operatic tunes 13.
In addition, be provided with welding muscle (scheming not shown) in the edge of module upper casing 2 and/or module lower casing 3, welding muscle and module upper casing 2 and/or module lower casing 3 are one-body molded, the embodiment of the present invention is melted welding muscle by ultrasonic bonding combines module upper casing 2 and module lower casing 3, but also can make otherwise to melt welding muscle, module upper casing 2 and module lower casing 3 are combined.
Fig. 5 b is another partial enlarged drawing of Fig. 4, in conjunction with Fig. 5 b, Fig. 2 and Fig. 4, because antenna 10 is plated in the side wall inner surfaces on module upper casing right side in Fig. 4, so there is no plating screen 11 on the sidewall outer surface on module upper casing right side in Fig. 4.
From Fig. 5 b, it can also be seen that, antenna 10 is plated in the side wall inner surfaces of module upper casing 2, in the groove that the junction of module upper casing 2 and module lower casing 3 forms, scribbles scolding tin 14.
The raw material that above-mentioned metal screen layer 11 preferably adopts are gold; gold can be protected antenna 10 better; prevent its oxidation; but also can adopt the raw material of other metals as metal screen layer 11, and metal screen layer 11 to be arranged on module casing outside be that other structures in order to prevent loud speaker module internal contact and are short-circuited with metal screen layer 11.
The above-mentioned loud speaker module that the clear embodiment of the present invention provides in detail, owing to antenna being plated in to module casing inner side, can prevent that antenna from touching other accessory, reduce the loss of antenna, can also prevent that antenna is oxidized, the part not contacting with antenna in the outside of module casing arranges metal screen layer simultaneously, can shield well the interference of outer signals to antenna.
In the mode of example, the loud speaker module proposing according to the present invention is described above with reference to accompanying drawing.But, it will be appreciated by those skilled in the art that the loud speaker module proposing for the invention described above, can also on the basis that does not depart from content of the present invention, make various improvement to the details that realizes wherein.Therefore, protection scope of the present invention should be determined by the content of appending claims.
