Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
Embodiment one:
As shown in Figure 1, the diaphragm of loudspeaker comprises the central part 11 that is positioned at the center and the 12a of ring portion that is positioned at marginal position, wherein central part 11 is generally the structure of rigidity with the high frequency characteristics of assurance product, and the 12a of ring portion is flexible material, guarantees that vibrating diaphragm can free vibration.Wherein, the present embodiment vibrating diaphragm is rectangular configuration, and the 12a of ring portion is the arcuate structure of depression or projection, and the bight of the rectangle ring 12a of portion is provided with decorative pattern, can guarantee vibrating diaphragm up-down vibration freely.
Preferably, present embodiment also is provided with reinforcement decorative pattern 121a and reinforcement decorative pattern 122a on the straight line of vibrating diaphragm, the present embodiment vibrating diaphragm is specially rectangle structure, two relative major axis limits are provided with reinforcement decorative pattern 121a, two relative minor axis limits are provided with reinforcement decorative pattern 122a, reinforcement decorative pattern 121a and reinforcement decorative pattern 122a all are positioned at ring portion 12a position placed in the middle, are the oblique line structure, with straight line setting in a certain angle.Because the length of major axis correspondence is bigger, therefore intensity is also hanged down easy deformation, therefore the bar number of present embodiment major axis reinforcement decorative pattern 121a is more than the bar number of minor axis reinforcement decorative pattern 122a, and preferred reinforcement decorative pattern 121a and reinforcement decorative pattern 122a extend to the position near vibrating diaphragm bight decorative pattern.This structure has effectively strengthened the intensity of the vibrating diaphragm ring 12a of portion, can suppress bad vibration mode such as the abnormal distortion of four straight lines of the 12a of ring portion or fold, improve that to cut apart vibration, polarization etc. bad, reduction THD, improve audition, thereby improved the acoustical behavior of product.
In addition, need to prove that the structure of vibrating diaphragm is not limited to the rectangular as shown structure, also can be square, on four isometric limits of the vibrating diaphragm ring 12a of portion, the structure decorative pattern identical with quantity is set all, thereby can promotes the intensity of the vibrating diaphragm ring 12a of portion, improve the acoustical behavior of product.
Embodiment two:
Fig. 2 is the structural representation of embodiment two vibrating diaphragms, as shown in the figure, the reinforcement decorative pattern is positioned at ring portion 12b position placed in the middle equally, the difference of present embodiment and embodiment one is, the reinforcement decorative pattern 122b of the reinforcement decorative pattern 121b of major axis and minor axis is the strip structure that is parallel to straight line, each limit of present embodiment is provided with two not isometric reinforcement decorative patterns, and the entire length of major axis reinforcement decorative pattern 121b is greater than the length of minor axis reinforcement decorative pattern 122b.This structure can promote the intensity of the vibrating diaphragm ring 12b of portion equally, improves the acoustical behavior of loud speaker.
Identical with embodiment one, present embodiment is not limited to the design that this vibrating diaphragm is rectangle structure, also can adopt square structure, be equipped with the reinforcement decorative pattern of the bar shaped that is parallel to straight line on four straight lines of the square vibrating diaphragm ring 12b of portion, can promote the intensity of the 12b of the ring portion straight line of this square vibrating diaphragm, promote the acoustical behavior of product.
Embodiment three:
As shown in Figure 3, the difference of present embodiment and embodiment one and embodiment two is, the reinforcement decorative pattern 122c of the reinforcement decorative pattern 121c of major axis and minor axis all comprises the bar shaped decorative pattern that is parallel to straight line and the decorative pattern of the oblique line shape that arranges at an angle with straight line, this pattern structure can promote the intensity of the vibrating diaphragm ring 12c of portion straight line equally, improves the acoustical behavior of loud speaker.
The reinforcement decorative pattern of same this structure is not limited to this rectangular vibrating diaphragm, also can adopt this structure for four axles at square vibrating diaphragm, all can strengthen the intensity of vibrating diaphragm ring portion, promotes the acoustical behavior of product.
Embodiment four:
As shown in Figure 4, the difference of present embodiment and above embodiment is, the reinforcement decorative pattern 122d of the reinforcement decorative pattern 121d of major axis and minor axis all is positioned at the 12d of ring portion near a side of central part 11, be a plurality of strip structures perpendicular to straight line, this structure can strengthen the 12d of ring portion near the intensity of central part 11 1 sides, improve intensity and the stability of vibrating diaphragm, thereby can promote the acoustical behavior of product.
Reinforcement decorative pattern in the schematic structure on major axis and the minor axis is distinguished to some extent, and the structure of the reinforcement decorative pattern of present embodiment can be applied to can improve vibrating diaphragm intensity equally in the vibrating diaphragm of square structure equally, promotes the acoustical behavior of product.
Embodiment five:
As shown in Figure 5, the difference of present embodiment and embodiment four is that the reinforcement decorative pattern 121e on the major axis and the reinforcement decorative pattern 122e on the minor axis all are positioned at the 12e of ring portion away from a side of central part 11, and is the structure perpendicular to the bar shaped of straight line setting.This structure can promote the vibrating diaphragm ring 12e of portion away from the intensity of central part 11 1 sides, improves the acoustical behavior of product.Same this structure also can be applied in the square vibrating diaphragm, to promote the intensity of its straight line.
Need to prove that be not limited among the above embodiment also can only arrange at one group of opposite side in the structure that is not limited to all arrange on this two groups of opposite side the reinforcement decorative pattern, preferably on the major axis limit, this improvement is also in protection range of the present utility model.
Under above-mentioned instruction of the present utility model; those skilled in the art can be in his improvement of the basic enterprising Xingqi of above-described embodiment and distortion; and these improvement and distortion; all drop in the protection range of the present utility model; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained the purpose of this utility model, and protection range of the present utility model is limited by claim and equivalent thereof.
