As the preferred scheme of one, between described the first antifreeze plate and loud speaker body, be equiped with the foam for sealing described front sound chamber.
As the preferred scheme of one, described the second antifreeze plate is installed on the madial wall and/or lateral wall of the first antifreeze plate.
As the preferred scheme of one, between described the second antifreeze plate and the first antifreeze plate, fix gluing.
Compared with prior art the beneficial effects of the utility model are: by fixing installing the first antifreeze plate on described loudspeaker support, this first antifreeze plate is between described phonate hole and loud speaker body, when guarantee is simple in structure, described the first antifreeze plate can play effectively every magnetic effect, and the magnetic flux at phonate hole place is reduced greatly; And by also install at least a slice the second antifreeze plate on described the first antifreeze plate, this second antifreeze plate can further reduce the magnetic flux at phonate hole place, the magnetic flux at phonate hole place is reduced to a very low scope, realize in ensureing mobile terminal high tone quality, solve because of the excessive inspiration iron of phonate hole magnetic flux pin, caused causing the problem such as noise and loud speaker inefficacy.Have simple in structurely, acoustical quality is good, the advantage of long service life.
Below in conjunction with drawings and Examples, the loadspeaker structure of a kind of mobile terminal described in the utility model is described further:
Brief description of the drawings
Fig. 1 is the structural representation of the loadspeaker structure of the utility model mobile terminal.
In accompanying drawing, the list of parts of each label representative is as follows:
1. bonnet, 101. phonate holes, 2.PCB, 3. loudspeaker assembly, 301. loud speaker bodies, 302. loudspeaker supports, 303. first antifreeze plates, 304. front sound chambeies, 305. rear sound chambeies, 306. second antifreeze plates, 307. foams.
Embodiment
In order more clearly to understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
More details are set forth in the following description so that fully understand the utility model; but; the utility model can also adopt other to be different from other modes described here and implement, and therefore, protection range of the present utility model is not subject to the restriction of following public specific embodiment.
The utility model embodiment provides a kind of loadspeaker structure of mobile terminal, and the utility model is referred to as mobile terminal, comprises that mobile phone, digital camera, PAD, palmtop PC and other have the mobile terminal device of loadspeaker structure.
With reference to Fig. 1, the loadspeaker structure of the new described mobile terminal of this practicality comprises bonnet 1 and the PCB(Printed Circuit Board of mobile terminal, claim again printed circuit board) 2, also comprise the loudspeaker assembly 3 being installed between described bonnet 1 and PCB2, described bonnet 1 is provided with a plurality of phonate holes 101 with loudspeaker assembly 3 places of adapting, described loudspeaker assembly 3 comprises loud speaker body 301, the loudspeaker support 302 that is arranged on the lateral wall of loud speaker body 301 and is tightly connected with described bonnet 1 and PCB2, and be installed on the first antifreeze plate 303 on described loudspeaker support 302 and between described phonate hole 101 and loud speaker body 301, sound chamber 304 before forming between described loud speaker body 301 and the first antifreeze plate 303, sound chamber 305 after forming between described loud speaker body 301 and loudspeaker support 302 and PCB2, on described the first antifreeze plate 303, also install at least a slice the second antifreeze plate 306.Wherein
The second described antifreeze plate 306 is installed on the madial wall and/or lateral wall of the first antifreeze plate 303.Apparently, the quantity of described the second antifreeze plate 306 and concrete installation site can be set according to actual conditions.In the present embodiment, as the preferred scheme of one, the quantity of described the second antifreeze plate 306 is a slice, and be installed on the lateral wall of the first antifreeze plate 303, ensure loudspeaker assembly 3 simple in structure, meet lightening demand in, can also effectively solve because of the excessive inspiration iron of phonate hole 101 magnetic flux pin, cause causing the problem such as noise and loud speaker inefficacy.Reach and improved after loadspeaker structure, do not increased mobile terminal complete machine thickness and ensure again very low and the double effects that can inspiration iron pin of phonate hole 101 magnetic flux.
