Abstract
The present invention provides a kind of mobile terminal, comprising: rear shell, loudspeaker and front housing；Wherein, the end face surrounding of loudspeaker is provided with the first seal, is arranged fluted in the inner wall of rear shell, and the inner wall of front housing is provided at least two locating grooves；Loudspeaker are set in the groove of rear shell, front housing seal closure is set in rear shell and the locating groove of front housing is engaged with the end face edge of loudspeaker by the sealing of the first seal, it is mutually isolated between the preceding sound chamber formed between the end face of loudspeaker and the inner wall of front housing so that the rear sound chamber formed between the side wall of the groove inner wall of rear shell, loudspeaker and the inner wall of front housing；The bottom of front housing is provided with sound outlet hole, forms sound channel between preceding sound chamber and sound outlet hole.As it can be seen that due to being not necessarily to seal by dispensing to be isolated between the sound chamber of front and back, if loudspeaker damage, loudspeaker are only needed to change, maintenance cost is lower.
Description
Technical field
The present invention relates to field of terminal technology more particularly to a kind of mobile terminals.
Background technique
Under normal conditions, the loudspeaker sound emitting mode of terminal is divided into two kinds: back side articulation type and side articulation type；It compares
In side articulation type, back side articulation type is put vulnerable to terminal to be blocked sound outlet hole and influences sound effect, therefore, user opposite side hair
Sound mode is increasingly favored, and using the terminal of side articulation type, proportion is also increasing in terminal market.
Fig. 1 is the local left view structural representation of traditional side pronunciation device.As shown in Figure 1, being in the sonification techniques of traditional side
Preceding sound chamber sound channel A shown in realization arrow, the end face lower edge of loudspeaker B foam can not be set and loudspeaker B and front housing C it
Between would generally there are gap D, cause be between preceding sound chamber E and rear sound chamber F conducting；In order to seal between loudspeaker B and front housing C
Gap D clicks and enters glue in the gap D usually between loudspeaker B and front housing C, thus by loudspeaker B and front housing so that front and back sound chamber is isolated
C becomes the entirety that can not be split.As it can be seen that needing replacing loudspeaker and front housing, therefore, maintenance cost if loudspeaker damage
It is higher.
Summary of the invention
The present invention provides a kind of mobile terminal, and maintenance cost is lower.
In a first aspect, the embodiment of the present invention provides a kind of mobile terminal, comprising: rear shell, loudspeaker and front housing；Wherein, loudspeaker
End face surrounding is provided with the first seal, is arranged fluted in the inner wall of rear shell, and the inner wall of front housing is provided at least two
Locating groove；
Loudspeaker are set in the groove of rear shell, and front housing seal closure is set in rear shell and the locating groove of front housing and the end of loudspeaker
Face edge is by the sealing engaging of the first seal, so that between the side wall of the groove inner wall of rear shell, loudspeaker and the inner wall of front housing
The rear sound chamber formed, it is mutually isolated between the preceding sound chamber formed between the end face of loudspeaker and the inner wall of front housing；The bottom of front housing
It is provided with sound outlet hole, forms sound channel between preceding sound chamber and sound outlet hole.
Mobile terminal provided in an embodiment of the present invention, comprising: rear shell, loudspeaker and front housing；Wherein, the end face surrounding of loudspeaker
It is provided with the first seal, is arranged fluted in the inner wall of rear shell, the inner wall of front housing is provided at least two locating grooves；Loudspeaker
It is set in the groove of rear shell, front housing seal closure is set in rear shell and the end face edge of the locating groove of front housing and loudspeaker is by the
The sealing engaging of one seal, so that the rear sound chamber formed between the side wall of the groove inner wall of rear shell, loudspeaker and the inner wall of front housing,
It is mutually isolated between the preceding sound chamber formed between the end face of loudspeaker and the inner wall of front housing；The bottom of front housing is provided with sound outlet hole,
Sound channel is formed between preceding sound chamber and sound outlet hole.As it can be seen that by front housing seal closure be set to rear shell on and front housing locating groove
Engage with the sealing of the end face edges of loudspeaker, makes to achieve the purpose that be isolated between rear sound chamber and preceding sound chamber, without in loudspeaker with before
It is sealed between shell by dispensing front and back sound chamber is isolated；Therefore, if loudspeaker damage, only change loudspeaker without replace front housing,
It is not only easy to maintenance, and maintenance cost is lower.
