A kind of sounding device set of half mould sets provided by the utility model, as shown in figs. 1-2, including module casing 1, it is described Module casing 1 can be to be enclosed by bottom surface 11 and inner wall 12, the structure of a side opening opposite with bottom surface 11, module casing 1 there is the side of opening can be fastened in external structure, enclose the chamber of sealing jointly with external structure.Module casing 1 The side wall on a side is eliminated, by external structure, the external structure is usually to install the electricity of sounding device set of half mould sets The shell etc. of sub- equipment, under isometric, this structure can optimize 1 internal chamber structure of module casing, increase chamber volume. The module casing 1 can be sealed by glue material and is adhesively fixed in the external structure, such as in the inner wall at place that is fastened and connected 12 with the either Nian Jie double-sided adhesive etc. of pre- gluing on the surface that external structure is mutually agreed with.

Sounding device set of half mould sets further includes the electrical connector 4 being set in advance in module casing 1, and with module casing 1 First structure part 2 discrete and for mutually agreeing with external structure.The contour structures of the first structure part 2 are respectively at described Module casing 1 mutually agrees with the external structure, can meet respectively when the module casing 1 and the external structure fasten It needs, so that closed position is mutually agreed with.The first structure part 2, which is connected on module casing 1 and crosses over, is pre-installed in mould On electrical connector 4 in group shell 1.The first structure part 2 is a separable structure member on the module casing 1, When installing the electrical connector 4 in sounding device set of half mould sets, separable first structure part 2 will not be to the installation of electrical connector 4 It causes to hinder, after the installation for completing electrical connector 4, then fixed upper first structure part 2 is installed, enables to sounding device set of half mould sets Assembling production process it is more smooth, production efficiency is higher, reduces the investment of manpower.

When first structure part 2 and the integrated molding of module casing 1, when inseparable, the installation of electrical connector 4 will be caused It hinders, it is necessary to which, using manually positioning is connected, working efficiency is low；And be provided separately first structure part 2 with module casing 1, it is electrically connected The installation of fitting 4 will be extremely convenient, and after installation is complete, first structure part 2 is being fixedly connected with module casing 1, so that it may So that module casing 1 mutually agrees with external structure, the difficulty of installation is simplified, improves production and assembly efficiency.In some realities It applies in example, the electrical connector 4 can also be other circuit boards, the application in other examples for FPCB plate This is not intended to limit.

In some embodiments, the first structure part 2 can be fixed on described by way of bonding or ultrasonic welding On module casing 1, it is also possible to be clamped, then is fixedly connected in modes such as access section gluing reinforcings with the module casing 1, as long as It is that module casing 1 and first structure part 2 first separate, the later period is fixedly connected by connection means, and the application is to its connection side Formula is not intended to limit.

In some embodiments, as shown in figs. 1-2, there is first chamber 6, second chamber 7 in the module casing 1 And the transition chamber thereof 8 between first chamber 6 and second chamber 7.The first structure part 2 is connected on module casing 1 The position of corresponding transition chamber thereof 8, forms between the first structure part 2 and module casing 1 and is connected to the first chamber 6 and second The clearance channel 3 of chamber 7 enables the first chamber 6 at 3 both ends of clearance channel to be connected to second chamber 7, plays its acoustics function It can act on, guarantee the acoustical behavior of sounding device set of half mould sets.

In some embodiments, as shown in figs. 1-2, the first chamber 6 in the module casing 1 and second chamber 7 Can be located in different planes, between there are differences in height, in order to enable first chamber 6 is connected to second chamber 7, module casing 1 bottom surface 11 for being located at 8 position of transition chamber thereof can be inclined surface, and the first chamber 6 convenient for making is connected to second chamber 7.

It in some embodiments, as shown in figs. 1-2, further include having sounding device list in the sounding device set of half mould sets Body 5, the sounding device monomer 5 can be set in first chamber 6, the electrical connector 4 pass through the clearance channel 3, one End be electrically connected with the sounding device monomer 5, the other end is electrically connected in transition chamber thereof 8 with external circuit, can by electric signal by Outside is transferred on sounding device monomer 5, makes its work.

In some embodiments, as shown in figs. 1-2, the opposite both ends of the first structure part 2 are connected to mould group shell On the inner wall 12 of 1 opposite sides of body, so that electrical connector 4 is during installation, transition chamber thereof 8 becomes the chamber of an open type, no The installation of electrical connector 4 can be caused to hinder；On the other hand, first structure part 2 is connect with the inner wall 12 of module casing 1, can After module casing 1 is fastened in external structure, the inner wall 12 and external structure of module casing 1, which form first structure part 2, to be pressed from both sides Cooperation is used, fixed is stronger, reduces unexpected fall off.Further, the first structure part 2 be used for The surface flush that the surface and 1 edge of module casing that external structure is agreed with are used to agree with external structure, guarantees mould group Degree of being flat and fit when shell 1 and the external structure fasten, the leakproofness after enhancing its connection.

In some embodiments, as shown in figs. 1-2, ladder is formed on some specific positions, external structure Difference, because this step difference is possible as two different components of external structure there are caused by difference in height, such as institute Module casing 1 is stated when on the shell for be fastened on electronic equipment, may be hindered with battery, at this moment, it is necessary to mould group Shell 1 carries out the adjustment of evacuation design, forms stair-stepping structure and is agreed with, the intersection of described two different components is past Toward not having leakproofness, then the sealing performance in order to guarantee sounding device set of half mould sets inner cavity chamber, this position generally require It is sealed on module casing 1, therefore, in the one side that the first structure part 2 mutually agrees with the external structure, is also provided with into Hierarchic structure enables it preferably to agree with the external structure；On the other hand, moreover it is possible to promote the sounding device half module The leakproofness of group inner cavity chamber.

In some embodiments, the module casing 1 or/and the first structure part 2 can distinguish integrated injection molding, Simplify production technology, improves its structural strength.

In some embodiments, sheet metal is additionally provided on the bottom surface 11 on the module casing 1 to replace injection molding material The cavity wall of material, for further reducing the wall thickness of module casing 1, increase chamber volume fills as far as possible to improve sounding Set the acoustical behavior of mould group.The sheet metal can be fixed in the module casing 1 by way of insert injection moulding, improve it Leakproofness, that is, bonding strength.

Although being described in detail by some specific embodiments of the example to the utility model, this field It is to be understood by the skilled artisans that example above merely to be illustrated, rather than in order to limit the scope of the utility model.This Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case where, to above embodiments It modifies.The scope of the utility model is defined by the following claims.
