The present invention is by the following technical solutions: a kind of loudspeaker go out sound structure, front at housing is provided with touch-screen, in housing, be provided with loudspeaker, the front of described housing is provided with the face-piece of opening hole, touch-screen is installed after through hole, at the front edge of touch-screen and the joining place at the face-piece back side, leave one and iris out sound gap; Before described loudspeaker with face-piece after form the front sound chamber of loudspeaker, this front sound chamber extends to the whole circle after face-piece and between housing, goes out Yu Qianyin chamber, sound gap and is communicated with.
The height in touch-screen of the present invention front is lower than the height in face-piece front,
Face-piece of the present invention is tabular or circular-arc, and mid portion forms through hole, face-piece outside, inner peripheral respectively backward bending extend, cross sectional shape formation concavity.
Before loudspeaker of the present invention with face-piece after concavity inside region form the front sound chamber of loudspeaker.
Through hole of the present invention be shaped as circle, ellipse, rhombus, square or rectangle.
Of the present inventionly go out sound gap and be: 0.8mm≤go out sound gap≤1.5mm.
Face-piece of the present invention top, bottom or two lateral location are below provided with loudspeaker, are shaped as circle, ellipse or square before loudspeaker.
Before loudspeaker of the present invention, be provided with speaker net.
After loudspeaker of the present invention, adopt loudspeaker bonnet that loudspeaker 5 are fixed on housing; Loudspeaker bonnet cross sectional shape is that spill is middle with protruding rib, between loudspeaker and loudspeaker bonnet protruding bar, is lined with sponge.
Before loudspeaker of the present invention, between the support of outmost turns and housing, be lined with sponge circle or silica gel ring; The front edge in the region that described loudspeaker and touch-screen and housing are linked to be, and between the face-piece back side, be provided with a circle sealing rib.
The present invention compared with prior art, at the front edge surface of touch-screen and the joining place at the face-piece back side, be provided with a circle and go out uniformly sound gap, the sound that loudspeaker send, the front sound cavity oscillations that utilizes face-piece to form improves audio quality, reduces distorsion, filter out the dry sound of high frequency, from going out sound gap, outwards sound, guarantee audio quality, appearance integral is attractive in appearance.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As depicted in figs. 1 and 2, loudspeaker of the present invention go out sound structure, and the front of the product shells 3 such as building conversational system main frame and extension set, Smart Home operating surface and panel computer is provided with face-piece 1, and positive is operating surface or display surface in the face of operator or beholder.Face-piece 1 is tabular or circular-arc, the material of face-piece 1 mid portion is removed formation through hole, outer, the inner peripheral bending extension backward respectively of face-piece 1, make face-piece 1 form concavity along the axial cross section shape of through hole, shape as shown in the H-H cross section of face-piece 1, through hole be shaped as circle, ellipse, rhombus, square or rectangle.After face-piece 1 through hole, touch-screen 2 is installed, the size in touch-screen 2 fronts is greater than the size of face-piece 1 through hole, the height in touch-screen 2 fronts is lower than the height in face-piece 1 front, at the front edge surface of touch-screen 2 and the joining place at face-piece 1 back side, leave one and iris out sound gap T, 0.8mm≤T≤1.5mm.Touch-screen 2 can also be display screen or the decorative lens such as liquid crystal display LCD, Thin Film Transistor (TFT) TFT, LED, and eyeglass is that material can be glass or polymethyl methacrylate PMMA as decorating.
In face-piece 1 top, bottom or two lateral location below, be provided with loudspeaker 5, loudspeaker 5 above be shaped as circle, ellipse or square, before loudspeaker 5, (vibrating diaphragm) is towards face-piece 1, loudspeaker 5 are the front sound chamber A of inside concavity vibrating diaphragm and face-piece 1 concavity inside region formation below loudspeaker above, this front sound chamber A extends to whole face-piece 1 circle between concavity inside region and housing 3 below that loudspeaker 5 are not installed, go out the inner ring that sound gap T is positioned at front sound chamber A, chamber A is communicated with front sound.In front sound chamber A, loudspeaker 5 be provided with above speaker net 8, the edge of speaker net 8 is fixed on housing 3, speaker net 8 is for blocking dust, when fore shell 1 is designed to can be from the structure of front dismounting time, can also improve the outward appearance of loudspeaker 5 and play the effect of protection loudspeaker 5 in dismounting loudspeaker 5 processes.
Loudspeaker 5 are arranged on housing 3, and the quantity of loudspeaker 5 is at least 1, be provided with loudspeaker 5 cavity is installed on the housing 3 of corresponding installation loudspeaker 5.At loudspeaker 5, adopt loudspeaker bonnet 4 that loudspeaker 5 are fixed on housing 3 below.Loudspeaker bonnet 4 cross sectional shapes are middle with protruding concavity, and spill is middle with protruding rib.Between loudspeaker 5 and loudspeaker bonnet 4 projections, be lined with sponge 6, make after loudspeaker 5, the region of relative closure forms rear sound chamber B between loudspeaker bonnet 4 projections and concavity, make loudspeaker 5 forward sound chamber A speak.
The present embodiment loudspeaker 5 are 2, are arranged on face-piece 1 bottom below, and T is 0.8mm.
Before loudspeaker 5, between the support of outmost turns and housing 3, be lined with a circle sponge circle or silica gel ring 7, for isolating front sound chamber A and the rear sound chamber B of loudspeaker, to improve audio quality.
The front edge in the region being linked to be at loudspeaker 5 and display screen 2, and between face-piece 1 back side, be provided with a circle sealing rib (9), outwards send along gap T after front sound chamber A vibration the past sealing of sound rib 9 inner sides that loudspeaker 5 are sent.
Loudspeaker of the present invention go out sound structure, the sound that loudspeaker 5 send, before utilizing, sound chamber A vibration improves audio quality, reduce distorsion, rear sound chamber B filters out the dry sound of high frequency, from the front edge surface of display screen 2 and joining place one circle at face-piece 1 back side, goes out uniformly sound gap T, outwards sounds, guarantee audio quality, the overall aesthetics of profile.The loudspeaker that solved when all can not there be loudspeaker sender at front, side and the back side go out mail topic.
