Description
Technical field
The present invention relates to terminal structure design field, more particularly, to a kind of mobile terminal.
Background technology
With the continuous development of technology, the more and more thinner that mobile terminal does, the also more and more higher of the requirement to performance, audio frequency is made
For a part therein, also to meet Consumer's Experience in continuous improving performance.Bottom goes out the mobile terminal of sound, due to sound out
Afterwards directly facing consumer, Consumer's Experience can be relatively good, and increasing mobile terminal goes out the scheme of sound the bottom of using.
At present commonly use bottom go out sound organization plan have following two：
1st, BOX scheme
This kind of scheme is speaker seal in upper and lower two casings, and upper and lower two casings are by glue or double faced adhesive tape Lai close
Envelope, loudspeaker passes through FPC and turns on, with the shell fragment on circuit board, the conducting realized with circuit board, and the advantage of this scheme is to protect
Card sound effectively seals, and shortcoming is exactly that cost is higher.
2nd, support dispensing encapsulation scheme
This kind of scheme is that the circuit board of loudspeaker position is cut away, and loudspeaker is fallen, and loudspeaker is connected to by a FPC
On circuit board, the shortcoming of this kind of scheme is exactly that sound is easily leaked, thus leading to sound performance to become in the position that is connected with casing of circuit board
Difference.If sealed front sound chamber it is necessary to stretch casing with the mode of foam, be used for being horizontally disposed with foam reach close
The effect of envelope, the thickness that this casing stretches out adds height that the thickness of foam specifies along with sound channel so that whole machine
Thickness must increase.
Content of the invention
Embodiments of the invention provide a kind of mobile terminal, for solve loudspeaker in prior art realize bottom go out sound steep
Cotton carries out sealing the problem leading to whole machine thickness to increase.
For reaching above-mentioned purpose, embodiments of the invention adopt the following technical scheme that：
The embodiment of the present invention provide a kind of mobile terminal, including fore shell, loudspeaker, loudspeaker support, pcb board, first seal,
Second seal, on described loudspeaker support, described loudspeaker support is fixed on described fore shell to described loudspeaker upside down
On, described pcb board is fixed on described fore shell, and described pcb board is provided with opening, and described fore shell is provided with sound channel, described raises
The sound that sound device sends can spread out of outside described fore shell by described opening and described sound channel, and described first seal is sealed in
Between described loudspeaker and described pcb board, described second seal is sealed between described sound channel and described pcb board.
The mobile terminal that the embodiment of the present invention is provided, raises one's voice by by loudspeaker upside down on loudspeaker support
Device support is fixed on fore shell, and is provided with opening on pcb board, is provided with sound channel on fore shell, makes the sound that loudspeaker sends
Sound is spread out of outside casing by opening and sound channel, realizes bottom and goes out sound.For the sealing in front sound chamber, by first seal and
Two seals are sealed.First seal is sealed between loudspeaker and pcb board, second seal be sealed in sound channel and
Between pcb board.Thus foam can be horizontally disposed with, between loudspeaker and pcb board with such as foam as seal
Gap is sealed, and the gap between pcb board and fore shell is sealed, because the thickness of the distance to fore shell for the loudspeaker and fore shell
Than larger it is sufficient to using the opening of pcb board and on fore shell the sound channel of setting reach the requirement that bottom goes out sound, and do not need
The thickness additionally increasing whole machine just can reach the effect of sealing.
