Abstract
The utility model discloses a loudspeaker module and relates to the technical field of electro-acoustic products. The loudspeaker module includes a shell. A single loudspeaker is arranged in the shell. The shell is provided with a sound hole. A side of the shell provided with the sound hole is provided with an arc-shaped face or an irregular face. A part of the single loudspeaker locates in the orthographic projection of the arc-shaped face or the irregular face. The sound holes are not arranged in the arc-shaped face or the irregular-shaped face designedly. The sound hole is overlapped with a part of the orthographic projection area of a sounding zone of the single loudspeaker. The zone of the arc-shaped face or the irregular-shaped face of the loudspeaker module provided by the utility model is high in mechanical strength and the loudspeaker module is low in damage rate and long in service lifetime. And sound given out by the loudspeaker module can be radiated perfectly, so that the loudspeaker module is high in acoustic performance.
Description
Technical field
The utility model relates to the electro-acoustic product technical field, particularly a kind of integrated loud speaker module.
Background technology
Develop rapidly along with electronic industry, portable electric appts is easy to carry with it, complete function, can meet many-sided demand such as people's online, communication and amusement and be favourably welcome, and as the loud speaker module of the important acoustic element of electronic equipment, also is widely used.Because the kind of portable electric appts is various, structure is also different, so it is not identical to be arranged on the structure of the loud speaker module in portable electric appts yet.
When design loud speaker module, that the position of phonate hole often is designed to is concentric with loudspeaker monomer, major axis is identical or minor axis is identical, this design can make the articulating region of phonate hole over against loudspeaker monomer, be the ball top of phonate hole over against loudspeaker monomer, and the size at phonate hole size and ball top is close, this design, can be so that the sound that loudspeaker monomer sends very perfectly radiate.
But exist in arcwall face or irregular 's loud speaker module at some shells, if adopt the design of phonate hole over against the generating region of loudspeaker monomer, the part of phonate hole will be positioned at arcwall face or irregular 's zone, will increase the difficulty of the processing of loud speaker module and assembling, also can fall the mechanical strength in the low module arcwall face of loud speaker or irregular zone, increase the damage probability of loud speaker module.In order to solve the problems of the technologies described above, phonate hole need to be avoided to arcwall face or irregular zone, thereby design littlely by phonate hole, it is the side that corresponding loudspeaker monomer is very little, thereby the sound that causes loudspeaker monomer to send can not very perfectly radiate, and then reduced the acoustical behavior of loud speaker module.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of loud speaker module, and this loud speaker module arcwall face or irregular zone machines intensity are large, damages probability low, long service life; And the sound that loudspeaker monomer sends can very perfectly radiate, and acoustical behavior is high.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of loud speaker module, comprise shell, contain loudspeaker monomer in described shell, described shell is provided with phonate hole, the shell that is provided with described phonate hole side is provided with arcwall face or irregular, the part of described loudspeaker monomer is positioned at described arcwall face or irregular 's orthographic projection, and described phonate hole is avoided described arcwall face or irregular 's region division, and the orthographic projection zone of described phonate hole and described loudspeaker monomer articulating region partly overlaps.
Wherein, described shell comprises the first housing, the second housing and the 3rd housing be combined as a whole, and described the first housing and described the 3rd housing are incorporated into the two ends of described the second housing, and described phonate hole is positioned on described the first housing.
Wherein, described loudspeaker monomer involving vibrations system and magnetic circuit system, described vibrational system is near described the first housing setting; Described vibrational system comprises vibrating diaphragm, and the centre position of described vibrating diaphragm is provided with the ball top.
Wherein, the width of described phonate hole is consistent with the width on described ball top.
After having adopted technique scheme, the beneficial effects of the utility model are:
Because the phonate hole of the utility model loud speaker module is avoided arcwall face on shell or the region division of irregular, and the orthographic projection zone of phonate hole and loudspeaker monomer articulating region partly overlaps.Phonate hole is avoided arcwall face or irregular the setting on shell, processing and the assembly difficulty of loud speaker module have been reduced, also guaranteed the mechanical strength in loud speaker module shell arcwall face or irregular zone simultaneously, reduce the damage probability of loud speaker module, extended the useful life of loud speaker module; The orthographic projection zone of phonate hole and loudspeaker monomer articulating region partly overlaps (as shown in Figure 2), the sounding area size that has guaranteed the size of phonate hole and loudspeaker monomer when making phonate hole depart from the arcwall face of shell or irregular zone is close, the sound that makes loudspeaker monomer send can very unobstructed radiateing, thereby guaranteed the perfection that loudspeaker monomer is sounded.Visible, the utility model loud speaker module is in the situation that guaranteed that phonate hole departs from arcwall face or irregular the zone of shell, guaranteed that the sound that loudspeaker monomer sends can very perfectly radiate, improve the acoustical behavior of loud speaker module, also promoted the overall performance of loud speaker module simultaneously.

Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
As shown in Fig. 1 and Fig. 2 are common, a kind of loud speaker module, comprise shell, and shell is combined into by the first housing 14, the second housing 12 and the 3rd housing 10, and the first housing 14 and the 3rd housing 10 are incorporated into respectively the two ends of the second housing 12.The first housing 14, the second housing 12 and the 3rd housing 10 surround the module inner chamber, contain loudspeaker monomer in the module inner chamber, loudspeaker monomer involving vibrations system and magnetic circuit system.The edge that the first housing 14 is provided with phonate hole 140, the first housings 14 is arcwall face 142, and the part of loudspeaker monomer is positioned at the orthographic projection of arcwall face 142.The size of the size of phonate hole 140 and the articulating region of loudspeaker monomer is close, and phonate hole 140 is avoided the region division of arcwall face 142, be phonate hole 140 misalignment the center of loudspeaker monomer, phonate hole 140 partly overlaps with the orthographic projection zone of loudspeaker monomer articulating region.The design at the center of the misalignment loudspeaker monomer of this phonate hole 140, when having guaranteed that phonate hole 140 is avoided the arcwall face 142 of the first housing 14, guaranteed that the sound that loudspeaker monomer sends can very perfectly radiate, and has improved the acoustical behavior of loud speaker module.
