Background

Along with the development of electronic technology and the wide popularization of smart phones, cell phone manufacturers compete more and more fiercely, the price war is in the stage of getting incandescent, who's cell-phone price is lower and who just takes the lead, and speaker module group supplier price reduction is inevitable trend, therefore has urgently waited to find a lower speaker module group design scheme of cost. The existing connection mode of the monomer kernel and the whole machine is as follows: the single kernel is implanted, the connection mode is a bonding pad type, the single kernel is connected with the whole machine through a metal bonding pad, the bonding pad of the kernel of the loudspeaker module is welded with one end of an FPC (or a wire), the bonding pad at the other end of the FPC (or the wire) is connected with the metal bonding pad, and the metal bonding pad is connected with a spring plate of the whole machine; the existing connection mode has the following defects: the integration level of the smart phone is higher and higher, so that the size of a loudspeaker module is smaller and smaller, and the space for assembling the FPC is insufficient; the FPC has higher cost, and the FPC bonding pad needs to be welded twice, so that the welding efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned conventional art's weak point, provide a speaker module.

The purpose of the utility model is achieved through the following technical measures: a speaker module, its characterized in that: the steel sheet is arranged on the side of the cavity and connected with the core, and the second connecting end corresponds to the joint of the whole machine.

As a preferable scheme, a pad is arranged on the core, and the first connection end is connected with the pad.

As a preferred scheme, the first connection ends and the pads are arranged in a one-to-one correspondence.

Preferably, the inner core is located in the cavity, and the first connection end is located on the side of the pad.

Preferably, the first connection end is located above the core and arranged perpendicular to the pad.

Preferably, the first connection end can be bent to contact with the surface of the pad.

Preferably, a tin plating layer is arranged on the outer side of the first connection end, and the first connection end and the bonding pad are fixed by soldering.

As a preferable scheme, a gold plating layer is arranged on the outer side of the second connecting end.

Owing to adopted above-mentioned technical scheme, compare with prior art, the utility model has the advantages that: the inner core is directly connected with the whole machine through the steel sheet by injection molding the steel sheet on the shell, so that the cost is reduced; meanwhile, the automatic sucking, bonding and twice welding operations of the FPC are reduced, and the manufacturing efficiency is improved.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Example (b): as shown in fig. 1-2, a speaker module includes a shell 1 and a core 2, a cavity for accommodating the core 2 is provided in the shell 1, a steel sheet is injected in the shell 1, the steel sheet includes a first connection end 3 and a second connection end 4, the first connection end 3 is located at a side of the cavity and connected with the core 2, a bonding pad 5 is provided on the core 2, the first connection end 3 is connected with the bonding pad 5, and the second connection end 4 is connected with the whole speaker. The inner core 2 is directly connected with the whole machine through the steel sheet by injection molding the steel sheet on the shell 1, so that the cost is reduced; meanwhile, the automatic absorption, bonding and twice welding operations of the FPC are reduced, and the manufacturing efficiency is improved.

The cavity sets up towards one side opening, in this embodiment, for setting up towards upside opening, the kernel is located the cavity, and when the installation kernel, cavity was put into from the opening part of cavity to kernel 2, later sealed glue of beating along circumference space is sealed.
