Outflow.Speaker hole 16 can be one, or it is multiple, it can be circular hole, or strip as shown in Figure 2
Shape.
Shell 1 is also provided with loudspeaker rhone 17 in the lower section of loudspeaker sound chamber 19, by the water in loudspeaker sound chamber 19 in weight
It is discharged via loudspeaker rhone 17 to outside shell 1 under power effect.Preferably, loudspeaker rhone 17 is perpendicular along the short transverse of shell 1
It is straight down-set, the export direction of loudspeaker rhone 17 towards shell 1 bottom direction, in order under the effect of gravity can be quick
Draining.It is to be appreciated that in other embodiments, loudspeaker rhone 17 can also be in a certain angle diagonally downward with vertical direction
Setting.
Further, loudspeaker rhone 17 is in substantially capillary, to utilize capillary attraction Quick drainage.It is preferred that
The width on ground, loudspeaker rhone 17 can be set to 1-2mm.Loudspeaker rhone 17 is equivalent to an elongated conduit, due to hair
The presence of thin phenomenon, loudspeaker rhone 17 can have certain suction to the water in loudspeaker sound chamber 19, along with the gravity of water itself
Effect, finally, under vertical state, can be such that the water in loudspeaker sound chamber 19 discharges along loudspeaker rhone 17, when water reaches out
When mouth, siphonage will be generated because of drop, so that drainage efficiency be significantly increased；When the width very little of loudspeaker rhone, to loudspeaker
The influence of sound chamber is smaller.
It is to be appreciated that the sound chamber discharge structure of the utility model, passes through the microphone rhone in capillary setting
With loudspeaker rhone, under vertical state, the gravity of the suction and water itself that are generated by capillary can be by microphone sound
Chamber and the intracavitary water of loudspeaker sound are quickly discharged, and draining is reliable；When draining groove width very little, influence of the rhone to sound chamber compared with
It is small；Structure is simple, is easy to apply.
