Abstract
The utility model discloses a kind of loud speaker module, comprise module shell and loudspeaker monomer, the module inner chamber of collecting loudspeaker monomer is formed in module shell, module shell comprises module upper casing and module lower casing, module upper casing is located at outside the protecgulum of loudspeaker monomer, module upper casing is injected with sheet metal, and sheet metal leads to the earth terminal for the application terminal grounding connection with loud speaker module.Loud speaker module of the present utility model, had not only been beneficial to thin type, but also can have ensured the stability that loud speaker coordinates with application terminal.
Description
Technical field
The utility model relates to electro-acoustic product technical field, specifically, relates to a kind of loud speaker module.
Background technology
Loud speaker module is the important acoustic element of portable electric appts, for completing the conversion between the signal of telecommunication and voice signal, is a kind of energy conversion device.The module shell of loud speaker module generally comprises module upper casing and module lower casing, and module upper casing and module lower casing surround the module inner chamber containing loudspeaker monomer jointly.
Existing loud speaker module, generally comprises module shell and loudspeaker monomer, and form the module inner chamber of the described loudspeaker monomer of collecting in described module shell, described module inner chamber is divided into the front operatic tunes and the rear operatic tunes by described loudspeaker monomer.Module shell comprises module upper casing and module lower casing, and loudspeaker monomer is generally installed on the position near module upper casing.In order to increase the space of the vibrational system vibration area of loudspeaker monomer, the main flow solution of existing Microspeaker is the plastic casing above vibration area is changed into injection molding steel disc structure on plastic casing to replace, this shell mechanism makes shell when meeting intensity, the thickness of shell can be reduced, relatively increase the volume of shell inner cavity, thus effectively expand the oscillation space of vibrational system.After but on shell, injection moulding arranges steel disc, the metal structure of steel disc can cause certain interference to the application terminal of loud speaker, the application terminal of loud speaker was interfered and poor stability with coordinating between loud speaker, reduce the stability of the application terminal of loud speaker, affect the quality of the application terminal of loud speaker.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and be not only beneficial to thin type, but also can ensure the loud speaker module of the stability that loud speaker coordinates with application terminal.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of loud speaker module, comprise module shell and loudspeaker monomer, the module inner chamber of the described loudspeaker monomer of collecting is formed in described module shell, described module shell comprises module upper casing and module lower casing, described module upper casing is located at outside the protecgulum of described loudspeaker monomer, described module upper casing is injected with sheet metal, and described sheet metal leads to the earth terminal for the application terminal grounding connection with loud speaker module.
Preferably, described earth terminal fixedly exposes and is located on described module upper casing.
Preferably, described earth terminal is electrically connected by electrical connector with described sheet metal.
Preferably, described sheet metal, described electrical connector and the equal injection moulding of described earth terminal are on described module upper casing, and described earth terminal exposes setting.
Preferably, described sheet metal, described electrical connector and described earth terminal are structure as a whole.
Preferably, described sheet metal is steel disc.
After have employed technique scheme, the beneficial effects of the utility model are:
Loud speaker module of the present utility model, module upper casing is injected with sheet metal, and sheet metal leads to the earth terminal for the application terminal grounding connection with loud speaker module.When the loud speaker module of this structure being installed to application terminal use, can effectively suppress the metal structure eliminating sheet metal to the interference of application terminal, ensure loud speaker module and the stability coordinated between application terminal, ensure the quality of the application terminal of loud speaker module.
In the utility model, earth terminal is located on described module upper casing, more firmly, facilitates the earth terminal of sheet metal and the application terminal grounding connection of loud speaker module.

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of loud speaker module, comprise module shell and loudspeaker monomer 1, the module inner chamber of collecting loudspeaker monomer 1 is formed in module shell, module shell comprises module upper casing 2 and module lower casing 6, and module upper casing 2 is located at outside the protecgulum of loudspeaker monomer 1, and module upper casing 2 is injected with sheet metal, in the present embodiment, sheet metal is steel disc 3.Steel disc 3 leads to the earth terminal 4 for the application terminal grounding connection with loud speaker module.
The earth terminal of steel disc 3 fixedly exposes to be located on module upper casing 2, more firmly, facilitates the earth terminal 4 of steel disc 3 and the application terminal grounding connection of loud speaker module.The earth terminal of steel disc 3 can adopt can spot-welded structures, the structure be screwed, the structure that can rivet can be made, structure that the structure that shell fragment can be adopted to contact connect, shell adopt conducting resinl to coordinate and other the structure be fixedly connected with realize being connected with the ground of the application terminal of loud speaker module.
In the present embodiment, earth terminal 4 is electrically connected by electrical connector 5 with steel disc 3; All injection moulding is on module upper casing 2 for steel disc 3, electrical connector 5 and earth terminal 4, and earth terminal 4 exposes setting, is convenient to loud speaker module when being installed on application terminal, earth terminal 4 and the application terminal grounding connection of steel disc 3; Steel disc 3, electrical connector 5 and earth terminal 4 are structure as a whole, but are not limited to integrative-structure.
The loud speaker module of the present embodiment, module upper casing 2 is injected with steel disc 3, and steel disc 3 leads to the earth terminal 4 for the application terminal grounding connection with loud speaker module.When the loud speaker module of this structure being installed to application terminal use, can effectively suppress the metal structure eliminating steel disc 3 to the interference of application terminal, ensure loud speaker module and the stability coordinated between application terminal, ensure the quality of the application terminal of loud speaker module.
The above is the citing of the utility model preferred forms, and the part wherein do not addressed in detail is the common practise of those of ordinary skill in the art.Protection range of the present utility model is as the criterion with the content of claim, and any equivalent transformation carried out based on technology enlightenment of the present utility model, also within protection range of the present utility model.
