Side, the end face surrounding convex setting position rib of pedestal, the end face of this location rib constitutes described second cemented surface, during installation the
One cemented surface and/or the second cemented surface are coated with glue-line, and the two is fixed together by this glue-line, and defining flange adapts to determine
Outside the rib of position.
Further, the outside of the end face surrounding of described pedestal its location rib corresponding has supporting surface, during installation, and described limit
The bottom surface of position flange contacts against on this supporting surface.
Further, the width of described defining flange is 0.1-0.5mm.
Further, described defining flange is a coil structures of surrounding Guan Bi, or, described defining flange includes some head and the tail
Adjacent flange sections.
Further, described location rib is a coil structures of surrounding Guan Bi, or, described location rib includes some head and the tail
Adjacent rib section.
A kind of Microspeaker, including the installation and positioning structure of Microspeaker upper cover described above Yu pedestal, described upper cover
Vibrational system and magnetic circuit system is contained in the cavity surrounded with pedestal.
Further, described vibrational system includes vibrating diaphragm and voice coil loudspeaker voice coil, and magnetic circuit system includes the frame being combined with pedestal, is arranged at
Magnet in frame, and the washer arranged on Magnet, in voice coil loudspeaker voice coil coordinates the gap between Magnet and washer and pedestal.
Compared to prior art, this utility model has the advantages that
Described defining flange and the setting of location rib, on the one hand can position the two when installing at upper cover and pedestal, from
And reduce the two glued difficulty of matching, on the other hand defining flange can be utilized effectively to prevent glue from overflowing, it is ensured that product appearance
Tidiness, thus avoid follow-up frictioning process, reduce production cost.
Below in conjunction with drawings and Examples, this utility model is described in further detail；But one of the present utility model is miniature raises
Sound device upper cover is not limited to embodiment with installation and positioning structure and the Microspeaker of pedestal.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present utility model；
Fig. 2 is the structural representation of pedestal of the present utility model；
Fig. 3 is generalized section of the present utility model.
Detailed description of the invention
Embodiment, refers to shown in Fig. 1-Fig. 3, and a kind of Microspeaker upper cover of the present utility model positions with the installation of pedestal
Structure, including upper cover 1 and pedestal 2, the bottom surface surrounding of upper cover 1 has the first cemented surface 11, pedestal 2 has and adapts to
Second cemented surface 21 of one cemented surface 11；The edge, bottom surface of upper cover 1 downwardly extends limited location flange 12, this defining flange
The width of 12 is 0.1-0.5mm, and preferred values is 0.2mm, and this defining flange 12 is positioned at outside the first cemented surface 11.Pedestal 2
End face surrounding convex setting position rib 22, the end face of this location rib 22 constitutes described second cemented surface 21, during installation the
One cemented surface 11 and/or the second cemented surface 21 are coated with glue-line (not embodying in figure), and the two is fixed together by this glue-line,
And defining flange 12 adapts to position outside rib 22.
In the present embodiment, the outside of the end face surrounding of described pedestal 2 its location rib 22 corresponding has supporting surface 23, during installation,
The bottom surface of described defining flange 12 contacts against on this supporting surface 23.
In the present embodiment, described defining flange 12 includes the flange sections that some head and the tail are adjacent, if described location rib 22 includes
The rib section that dry head and the tail are adjacent.
During installation, on the first cemented surface 11 of upper cover 1, first coat glue, constitute glue-line；Then, by determining on pedestal 2
