Preferably, described sound mouth connects described the first housing and described the second housing.
Preferably, at described sound mouth place, be also provided with an Air Filter.
Preferably, described Air Filter is fixed in described the second housing.
Positive progressive effect of the present utility model is: loudspeaker hermetically-sealed construction of the present utility model has reduced the complete machine thickness of mobile terminal device, makes the setting of loudspeaker and sound mouth position freer, the impact that can also more effectively resist salt fog and sand and dust etc.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of loudspeaker hermetically-sealed construction of the prior art.
Fig. 2 is a schematic diagram of the loudspeaker hermetically-sealed construction of the utility model preferred embodiment.
Fig. 3 is the another schematic diagram of the loudspeaker hermetically-sealed construction of the utility model preferred embodiment.
Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 2, loudspeaker hermetically-sealed construction of the present utility model comprises loudspeaker 2, one first housing 3, one second housing 4.The direction indication mobile terminal device lateral direction making progress in figure, side direction in downward direction indication mobile terminal device.The face down of the loudspeaker 2 in figure, namely towards the inner side of mobile terminal device, this is different from the front of general mobile terminal device inside trumpet toward the outer side.
As seen from the figure, the first housing 3 and the second housing 4 are affixed, and particularly, both are that the mode by ultrasonic bonding is fixed together.Ultrasonic bonding can allow two housings be linked to be a monoblock, reaches the effect of sealing, sound insulation, waterproof, protection against the tide.In Fig. 2, dashed circle place represents that the first housing and the second housing adopt the position of ultrasonic bonding.
On the second housing 4, there is an opening 41, the edge Joint of the edge of loudspeaker 2 and opening 41.Like this, the back side of loudspeaker 2 and the first housing 3 and the second housing 4 have just formed a rear sound chamber 6.
As shown in Figure 3, loudspeaker hermetically-sealed construction of the present utility model also comprise one the 3rd housing 5, the three housings 5 and the second housing 4 affixed, particularly, both are that the mode by ultrasonic bonding is fixed together.In Fig. 3, dashed circle place represents that the second housing and the 3rd housing adopt the position of ultrasonic bonding.Meanwhile, the front of loudspeaker 2 and the second housing 4 and the 3rd housing 5 form a front sound chamber 7.
So, between the first above-mentioned housing 3 and the second housing 4, the second housing 4 and the 3rd housing 5, all adopt the mode of ultrasonic bonding to be fixed together, loudspeaker 2 are also fixing by the first housing 3 and the second housing 4, when loudspeaker 2 work produce vibration, the vibration of the 3rd housing 5 can not resonated with the generation of vibration of loudspeaker 2 like this.
