Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, a kind of audio cavity structure device is provided, and this audio cavity structure device can be integrated in sound chamber, loud speaker and antenna in a module, thereby this device can also reduce to take volume when realizing the multiple product function.
Its technical scheme is as follows:
A kind of audio cavity structure device, comprise antenna body and bracket shell, and antenna body is fixedly mounted on described bracket shell, and described bracket shell is provided with cavity, is provided with the accommodating position of loud speaker and sound chamber in cavity.
By loud speaker being arranged on the accommodating position of described loud speaker, described audio cavity structure device can be integrated in sound chamber, loud speaker and antenna in same module, thereby this audio cavity structure device can also reduce to take volume when realizing the multiple product function, its reliable in structure, be conducive to reduce the volume of mobile digital product.In addition, antenna body is fixedly mounted on bracket shell, can improves the bulk strength of described device, be conducive to simplify assembly technology.
Further, described bracket shell is provided with indentation, and described antenna body is fixedly mounted on the position of described indentation, and this antenna body and described indentation suitable.Thereby described audio cavity structure device can further reduce to take volume, thereby more be conducive to reduce the volume of mobile digital product.
Further, described antenna body is provided with ，Gai inner space, inner space and communicates with described cavity.Described inner space communicates and can form unified cavity with cavity, thereby can be under same volume, the scope in expansion sound chamber, thus be conducive to realize better acoustical quality.
Further, described antenna body is the LDS antenna body, and this LDS antenna body comprises antenna holder and LDS coating, and LDS coating covers on the outer wall of described antenna holder.
Further, in described cavity, be provided with inserts, this inserts by in-mould injection on described bracket shell.Thereby, described antenna body, inserts, bracket shell can form unified part, are conducive to simplify assembly technology, and by inserts by in-mould injection on described support, can improve the whole impact strength of part, this part can improve the intensity of complete machine after assembling.In addition, described inserts can be injection molded by stainless steel material, and such stainless steel inserts can also doublely be done magnetic conduction sheet, can prevent that product from use having tiny iron powder adsorption on loud speaker and affecting speaker performance.
Further, described audio cavity structure device also includes loud speaker, and this loud speaker is arranged on the accommodating position of described loud speaker.
Above-mentioned LDS antenna body refers to the antenna of making by laser active surface lines metallization process, the abbreviation that LDS is Laser Direct Structuring, i.e. laser direct structuring technique.
The beneficial effects of the utility model are: described audio cavity structure device can be integrated in sound chamber, loud speaker and antenna in same module, thereby this audio cavity structure device can also reduce to take volume when realizing the multiple product function, its reliable in structure, be conducive to reduce the volume of mobile digital product.
