To achieve these goals, the utility model by the following technical solutions: a kind of Microspeaker, comprises magnetic circuit system, vibrational system and support system; Described magnetic circuit system comprises frame, be contained in magnet in frame and washer; Described vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm, and described support system comprises front cover component and shell, it is characterized in that: described front cover component comprises the first housing and the second housing that match with described shell; Described first housing and described second case weld are fixed, and are positioned at the top of described vibrating diaphragm; Bond near described second housing of described vibrating diaphragm and the edge part of described vibrating diaphragm; Described front cover component and described shell hot melt are fixed.
Improve as one, the cross section of described first housing and described second housing is rectangle.
Improve as one, the horizontal range between described first housing and two sides of described second housing is all less than or equal to the horizontal range of described shell both sides, and matches fixing with described shell.
Improve as one, described first housing and described second housing are made up of metal material or other materials.
Improve as one, the centre position of described vibrating diaphragm is combined with reinforcement part; The inward flange of described vibrating diaphragm is surrounded on the periphery of described reinforcement part.
Improve as one, described Microspeaker also comprises two electrical connectors, is connected and fixed with two ends of described voice coil loudspeaker voice coil.
Improve as one, described Microspeaker also comprises two Air Filters, is covered in the surface of the acoustic aperture of described Microspeaker.
Compared to prior art, in the utility model, be the front cover component be made up of two housings by the front design of Microspeaker, and adopt the mode of welding to connect together, simplify the moulding process of protecgulum, ensure that the stability of protecgulum; On the other hand, one of them housing and vibrating diaphragm bond fixing, can strengthen the intensity at vibrating diaphragm edge, improve the stability at adhesive tape edge, and vibrating diaphragm is not easy distortion.

Embodiment
Below in conjunction with accompanying drawing, describe the utility model content in detail:
Embodiment:
Refer to shown in Fig. 1, the utility model Microspeaker comprises magnetic circuit system 13, vibrational system 14 and support system; Magnetic circuit system 13 comprises frame 1, be contained in magnet 2 in frame and washer 3; Vibrational system 14 comprises voice coil loudspeaker voice coil 4 and vibrating diaphragm 5, and support system comprises front cover component 12 and shell 9, and wherein, front cover component 12 comprises the first housing 10 and the second housing 11 matched with shell 9; First housing 10 and the second housing 11 are welded and fixed, and are positioned at the top of vibrating diaphragm 5, and the second housing 11 near vibrating diaphragm 5 bonds with the edge part of vibrating diaphragm 5; Front cover component 12 and shell 9 hot melt are fixed.
In concrete implementation process, first the first housing 10 is connected by the mode of laser welding with the 2 11, composition front cover component 12, then the second housing 11 and the edge part of vibrating diaphragm 5 is bondd fixing, can prevent welding process from causing damage to vibrating diaphragm 5 like this; As shown in Figure 2, shell 9 is provided with hot molten column 16, the position of two upper corresponding hot molten columns 16 of housing (10 and 11) is provided with the avoiding structure matched with it, after hot molten column 16 hot melt, two housings (10 and 11) are fixed on shell 9, complete the location with shell 9.
For Microspeaker, by technique scheme, front-cover structure is set to two housings be welded and fixed, simplifies the moulding process of protecgulum 12, and ironed relative to traditional front-cover structure, enhance the stability of protecgulum 12; Meanwhile, the second housing 11 and the edge part of vibrating diaphragm 5 bond fixing, can strengthen the intensity at vibrating diaphragm 5 edge, make vibrating diaphragm 5 not yielding, improve its stability.
In this implementation process, the cross section of the first housing 10 and the second housing 11 is rectangle, is convenient to combine with the shell 9 of Microspeaker, forms the cavity of collecting magnetic circuit system and vibrational system.
