Fig. 2 is the cutaway view of the sound cavity apparatus of the utility model embodiment.
Fig. 3 is the sound cavity apparatus decomposing schematic representation of the utility model embodiment.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Below, will combine accompanying drawing, the embodiment of the utility model is described in detail.
As shown in Figures 2 and 3; The utility model provides a kind of sound cavity apparatus; Said sound cavity apparatus comprises casing 1, is arranged on circuit board 2, loud speaker 3 and sound chamber lid 4 on the said casing 1; The diapire of said casing 1 is provided with flange 11; The inboard of this flange 11 forms the cavity of ccontaining said loud speaker 3, and said cavity and said sound chamber lid 4 form sound chamber 111, and said circuit board 2 comprises that first surface 21 reaches and said first surface 21 opposing second surface 22; The first surface 21 of said circuit board 2 is provided with circuit board electric conductor 211; Said loud speaker 3 is provided with loud speaker electric conductor 31, and said sound chamber lid 4 is provided with the sound chamber lid electric conductor 41 that is electrically connected with said loud speaker electric conductor 31 and said circuit board electric conductor 211 respectively, and the upper surface of said sound chamber lid 4 is not less than the second surface 22 of said circuit board 2.The second surface 22 that the upper surface of said sound chamber lid 4 is not less than said circuit board 2 is meant particularly, and said sound chamber lid 4 is hollowed out with said circuit board 2 corresponding zones, makes sound chamber lid 4 can pass circuit board 2.Can reduce the thickness of circuit board 2 itself like this; Also reduced the integral thickness of the electronic product of using this sound cavity apparatus; And pass circuit board 2 because of sound chamber lid 4; So the thickness of loud speaker 3 does not receive the distance affects between circuit board 2 and the casing 1, not only can rationally utilize its complementary space of electronic product, also practice thrift cost because selecting conventional loud speaker 3 for use.
