Description
Technical field
The present invention relates to field of terminal technology, particularly relate to a kind of mobile terminal.
Background technology
Under normal circumstances, the loudspeaker sound emitting mode of terminal is divided into two kinds: back side articulation type and side pronunciation
Mode；Compared to side articulation type, back side articulation type is easily put by terminal and is blocked sender and affect sound
Audio fruit, therefore, user's offside articulation type is increasingly favored, and uses the terminal of side articulation type at end
In end market, proportion is the most increasing.
Fig. 1 is the partial left TV structure schematic diagram of tradition side pronunciation device.As it is shown in figure 1, tradition side is sent out
In sound technology, in order to realize the front sound chamber sound channel A shown in arrow, the end face lower limb of loudspeaker B without
Method arranges foam and would generally leave gap D between loudspeaker B and fore shell C, causes front sound chamber E and rear sound
It it is conducting between the F of chamber；In order to seal gap D between loudspeaker B and fore shell C with sound chamber before and after isolation,
The generally gap D between loudspeaker B and fore shell C clicks and enters glue, thus by loudspeaker B and fore shell C
Become the entirety that can not be split.Visible, if loudspeaker damage, then need to change loudspeaker and fore shell,
Therefore, maintenance cost is higher.
Summary of the invention
The present invention provides a kind of mobile terminal, and maintenance cost is relatively low.
First aspect, the embodiment of the present invention provides a kind of mobile terminal, including: back cover, loudspeaker and front
Shell；Wherein, the end face surrounding of loudspeaker is provided with the first seal, is provided with groove in the inwall of back cover,
The inwall of fore shell is provided with at least two locating groove；
Loudspeaker are arranged in the groove of back cover, fore shell seal closure be located on back cover and fore shell locating groove with
The end face edge of loudspeaker seals engaging by the first seal, so that the side of the groove inner wall of back cover, loudspeaker
The rear sound chamber formed between wall and the inwall of fore shell, and formed between the end face of loudspeaker and the inwall of fore shell
Front sound chamber between mutually isolated；The bottom of fore shell is provided with sender, shape between front sound chamber and sender
Become sound channel.
The mobile terminal that the embodiment of the present invention provides, including: back cover, loudspeaker and fore shell；Wherein, loudspeaker
End face surrounding is provided with the first seal, is provided with groove in the inwall of back cover, and the inwall of fore shell sets
It is equipped with at least two locating groove；Loudspeaker are arranged in the groove of back cover, and fore shell seal closure is located on back cover
And the locating groove of fore shell is engaged by the first seal sealing with the end face edge of loudspeaker, so that back cover
The rear sound chamber formed between groove inner wall, the sidewall of loudspeaker and the inwall of fore shell, with the end face of loudspeaker with
Between the inwall of fore shell formed front sound chamber between mutually isolated；The bottom of fore shell is provided with sender, front
Sound channel is formed between sound chamber and sender.Visible, it is located on back cover and fore shell by fore shell seal closure
The end face edge of locating groove and loudspeaker seal and engage, make to reach between rear sound chamber and front sound chamber to isolate
Purpose, and without being sealed by a glue with sound chamber before and after isolation between loudspeaker and fore shell；Therefore, if loudspeaker
Damage, the most only change loudspeaker and without changing fore shell, the most easy to maintenance, and maintenance cost is relatively low.
