Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to further detailed description.
As shown in Figures 1 to 4, microphone device involving vibrations system, magnetic circuit system and accommodate the fixedly shell 1 of vibrational system, magnetic circuit system.Wherein vibrational system comprises vibrating diaphragm 21 and the voice coil loudspeaker voice coil 22 that is incorporated into vibrating diaphragm 21 1 sides; Magnetic circuit system comprises washer 31, magnet 32 and the basin frame 33 of combination successively, and basin frame 33 comprises sidewall and diapire 330, and washer 31 and magnet 32 are incorporated on the diapire of basin frame 33.Voice coil loudspeaker voice coil 22 is electrically connected to the external circuit of terminal electronics, is controlled the operating state of voice coil loudspeaker voice coil 22 by external circuit, and voice coil loudspeaker voice coil 22 is connected after the signal of telecommunication, stressed up-down vibration in the magnetic gap forming at magnetic circuit system, thus further drive vibrating diaphragm 21 vibrations to produce sound.Microphone device of the present invention can be also loud speaker module for loudspeaker monomer, and shell 1 can be the shell of monomer, also can in module with the shell of basin frame 33 secure bond, all in protection scope of the present invention.
Preferably, the structure that basin frame 33 of the present invention is combined for buckle with shell 1, the upper end of two minor axis sidewalls 332 of basin frame 33 is provided with trip 3320, and the inner side of support arm 11 is provided with near the position of basin frame 33 minor axis sidewalls 332 the screens portion 110 coordinating with trip 3320.Basin frame 33 is during with shell 1 assembling, and basin frame 33 is exerted pressure and made the trip 3320 of two minor axis sidewall 332 upper ends be expressed to the position of buckle position 110, and trip 3220 is matched with buckle position 110.Wherein buckle position 110 is to the structure near minor axis sidewall 332 projections; The upper end of trip 3320 comprises two bulge-structures that extend to horizontal direction respectively, and the downside of bulge-structure is respectively equipped with concave inward structure; After basin frame 33 is combined with shell 1 buckle, bulge-structure is positioned at the upside of buckle position 110, and buckle position 110 is arranged in concave inward structure, as shown in Figure 3 and Figure 4.In addition, for the ease of trip 3220, be combined with the buckle of buckle position 110, in the upper side corner sections of trip 3220 and the lower side corner sections of buckle position 110, be equipped with the guide part of the arc that material forms.This in trip 3220 and buckle position 110 in conjunction with time the position that first touches the structure of guide part is set, the upper surface that is conducive to trip 3220 snaps fit onto on buckle position 110 after slipping over the lower surface of buckle position 110.
Basin frame of the present invention 33 with shell 1 by buckle and NAG mode secure bond makes magnetic circuit system be not easy to come off from shell 1, thereby improved the firm degree of magnetic circuit system and shell 1 combination, thereby improved the stability of product.And this structure do not need the structures such as reserved gluing position, assembly technology is simple.
In addition, the invention is not restricted to the structure that this minor axis sidewall 332 is combined with shell 1 buckle, also major axis sidewall 331 can be combined with shell 1 buckle, or minor axis sidewall 332 and major axis sidewall 331 all pass through the mode secure bond of buckle with shell 1, all can realize the strong bonded of magnetic circuit system and shell 1, guarantee the stability of product.Above-mentioned improvement project is also all in protection scope of the present invention.
Under above-mentioned instruction of the present invention; those skilled in the art can carry out other improvement and distortion on the basis of above-described embodiment; as the structure of basin frame and shell is not limited to rectangle, it can be also circular configuration; and these improvement and distortion; all drop in protection scope of the present invention; it will be understood by those skilled in the art that just better explanation object of the present invention of above-mentioned specific descriptions, protection scope of the present invention is limited by claim and equivalent thereof.
