Wall, lateral outer side wall 322 and the 3rd chamber 36 of formation of laterally inboard wall 323.Especially, the 3rd chamber by separates into multiple
Small chamber.3rd chamber is corresponding with second chamber, when the first housing 31 and the second housing 32 are combined, second chamber
Cooperated with the 3rd chamber, form a sealed big chamber.Especially, the chamber opened by separates of second chamber
The chamber opened by separates with the 3rd chamber is mutually corresponding.
As shown in figure 17, buckle structure 325 is provided with the roof of the second housing 32.As shown in Figure 18, in the second housing
32 bottom wall is provided with buckle structure 325.
In the illustrated embodiment of the present invention, by snapping connection together between the first housing and the second housing, but
Not limited to this, can also be linked together with other connected modes known to persons of ordinary skill in the art, such as screw, bonding
Agent etc..
In an embodiment of the invention, in the first chamber, second chamber and the 3rd chamber filled with air, so
And other acoustic materials can also be filled.
In the speaker main of the present invention, by closing is set between the first housing and the second housing of speaker main the
One chamber, second chamber and the 3rd chamber, have effectively blocked the sound of loudspeaker to propagate to microphone pickup hole along case material
Near, isolate the sound of loudspeaker, weaken and even avoid sound interference of the supersound projector to microphone pickup hole, effectively
Improve the microphone pickup effect of audio amplifier.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this
On the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to correlation technique feature, these
Technical scheme after changing or replacing it is fallen within protection scope of the present invention.
