Description
Technical field
The utility model relates to electro-acoustic product technical field, particularly a kind of Microspeaker.
Background technology
Along with the progress of current science and technology, mobile phone is more and more tending towards lightening development, consumer is more and more higher for the requirement of mobile phone, select lightening mobile phone to become a kind of fashion, this is just also more and more higher to mobile phone speaker matter and performance requirement, and therefore Microspeaker can obtain better acoustical behavior and tonequality in the minimized while of thickness becomes a kind of trend of follow-up developments.
At present a lot of clients have strict restriction for the leakage field of Microspeaker, Microspeaker leakage field seriously will cause mobile phone antenna radio frequency bad, how at loud speaker acoustical behavior optimum, do not increase on the basis of product size leakage field minimized and becomes inexorable trend.Therefore, need to provide a kind of leakage field phenomenon that can effectively improve product, can not affect again the Microspeaker of other partial properties of Microspeaker, to adapt to the current market demand.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Microspeaker, can effectively improve the leakage field phenomenon of product, and does not affect the work of other structures in Microspeaker, thereby improves the magnetic property of Microspeaker.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Microspeaker, comprise magnetic circuit system, described magnetic circuit system comprises washer, magnet and the basin frame of combination successively, described basin frame comprises diapire and sidewall, described washer and described magnet are incorporated into the center of described basin frame diapire, wherein, are provided with the reinforcement part of thickening on described sidewall near the position of described diapire.
In addition, preferably scheme is, the sidewall of described basin frame comprises sidewall body, and the inner side of described sidewall body is provided with described reinforcement part near the part of described diapire, and described sidewall is step-like structure near a side of described magnet.
In addition, preferred scheme is that described sidewall body is identical with the thickness of described diapire with the thickness sum of described reinforcement part.
In addition, preferably scheme is, goes back involving vibrations system, and described vibrational system comprises vibrating diaphragm and the voice coil loudspeaker voice coil that is incorporated into described vibrating diaphragm downside, and described magnetic circuit system forms the magnetic gap of accommodating described voice coil loudspeaker voice coil.
Adopt after technique scheme, compared with traditional structure, the utility model easily produces magnetically saturated position near diapire place and is provided with reinforcement part on basin frame sidewall, and reinforcement part makes the wall thickness thickening of this part, thereby can improve magnetic saturation, the magnetic property of improving product; Because sidewall is not thickeied except other parts near diapire position, thereby can not hinder the normal work of voice coil loudspeaker voice coil, guarantee the acoustical behavior of product.
Accompanying drawing explanation
By below in conjunction with accompanying drawing, the utility model being described, above-mentioned feature of the present utility model and technological merit will become apparent and easily understand.
Fig. 1 is the stereo decomposing structural representation of the utility model Microspeaker;
Fig. 2 is the cross-sectional view of Microspeaker shown in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further detailed description.
As depicted in figs. 1 and 2, Microspeaker, involving vibrations system, magnetic circuit system, and accommodate the shell 1 of vibrational system and magnetic circuit system, wherein vibrational system comprises vibrating diaphragm 21 and is incorporated into the voice coil loudspeaker voice coil 22 of vibrating diaphragm 21 downsides; Magnetic circuit system comprises washer 31, magnet 32 and the basin frame 33 of combination successively, and magnetic circuit system forms the magnetic gap of accommodating voice coil loudspeaker voice coil 23.
The basin frame 33 of magnetic circuit system comprises diapire 331 and sidewall 332, and sidewall 332 is mutually vertical with diapire 331, and diapire 331 is rectangular configuration, is distributed with four sidewalls 332 on the four edges of rectangular bottom wall 331; Magnet 32, washer 31 are incorporated into the center of basin frame diapire 331, and sidewall 331, the diapire 332 of magnet 32, washer 31 and basin frame 33 surround magnetic loop jointly.In gap between magnet 32, washer 31 and sidewall 331, be provided with the magnetic gap of accommodating voice coil loudspeaker voice coil 22, in voice coil loudspeaker voice coil 22, connect the effect up-down vibration that is subject to Ampere force in the magnetic field that can form at magnetic circuit system after the signal of telecommunication.
For the magnetic circuit system of this structure, easily there is magnetic saturation phenomenon in the position in basin frame 33 bights, and the magnetic field that magnet 32 produces is not fully utilized, and is unfavorable for improving the magnetic property of magnetic circuit system.Conventionally can reduce leakage field by the mode of the thickness of thickening basin frame 33, but this structure can reduce the size of other parts, as the space of magnetic gap can reduce, in order to guarantee that voice coil loudspeaker voice coil 22 does not collide magnetic circuit system, the size of magnet 32 can only be reduced again, the acoustical behavior of product can be affected equally.Therefore, the present embodiment is provided with reinforcement part 330 at the magnetically saturated sidewall 332 of easy generation near the position of diapire 331.As shown in Figure 2, basin frame sidewall comprises sidewall body 3320, at sidewall body 3320, near the position of diapire 331, be provided with reinforcement part 330, add behind reinforcement part 330, the wall thickness of sidewall 332 downsides is greater than the wall thickness of the sidewall body 3320 of upside, makes sidewall 332 inner sides (near internal magnet one side) form step-like structure.This structure can reserve enough spaces for voice coil loudspeaker voice coil 22 on the one hand, prevents voice coil loudspeaker voice coil 22 and the collision of magnetic circuit system sounding; At basin frame 33, easily produce the wall thickness thickening of magnetically saturated position on the other hand, thereby can not affect the normal work of vibrational system, but also can improve leakage field phenomenon, improve the acoustical behavior of product.
In the present embodiment, the thickness sum of sidewall body 3320 and reinforcement part 330 is identical with the thickness of diapire 331.The present embodiment be will be tabular the bending of basin frame raw material after form the basin frame of moulding, then the part of sidewall upside is gone material to make the madial wall of basin frame form step-like structure.
In addition, it should be noted that, the thickness sum of sidewall body 3320 and reinforcement part 330 also can be greater than or less than the thickness of diapire 331, and 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 carry out other improvement and distortion on the basis of above-described embodiment; and these improvement and distortion; all drop in 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.
