A part of the through-hole of conductive magnetic yoke 31 and the centring magnet 321 as the back cavity 5, the center magnetic conductive board 322 are equipped with
Acoustic aperture 42 after second to be connected with the through-hole.
Because acoustic aperture 41 can not reach best and imitate with 5 air circulation of back cavity after four first of 31 four corners of conductive magnetic yoke
Fruit, therefore after the present embodiment is equipped with second be connected to the through-hole in conductive magnetic yoke 31 and centring magnet 321 on center magnetic conductive board 322
Acoustic aperture 42, as acoustic aperture after at the 5th.Acoustic aperture 42 together constitutes setting in magnetic circuit system after acoustic aperture 41 and second after four first
Rear acoustic aperture 4 on system.Wherein, at the 5th after acoustic aperture can not only play the role of dilatation back cavity 5, moreover it is possible to solve because of small-sized makeup
It sets vibrational system and magnetic circuit spacing is small, the acoustic resistance of vibration can become larger so that the problem of stability of vibration system is deteriorated.
Need exist for supplement be：321 central area of centring magnet (is weighed to the BL of acoustical generator by drive system in acoustical generator
One parameter of intensity) contribution is less than borderline region, and it therefore, will be in centring magnet 321 in the case where 5 volume of back cavity is limited
Heart district domain hollows out, and to increase back cavity volume, contributes to the performance for promoting product.Although the region that centring magnet 321 hollows out is to magnetic
The influence of the BL values of road system 3 is small, but how many or in the presence of influence.If the area of knockout of centring magnet 321 is too big,
Influence to the BL values of magnetic circuit system 3 cannot be ignored.Area of knockout is excessive, and the BL values of magnetic circuit system 3 will be smaller, production
The performance of product will be lower.Therefore, it is necessary to find a range of balance so that centring magnet 321 hollows out 5 volume of increased back cavity
Magnetic circuit system BL values are greater than to the lifting capacity of properties of product and reduce the amount for causing properties of product to reduce, to realize to product
The optimization of energy.It is learnt by emulation, when the volume that centring magnet 321 hollows out accounts within the 35% of centring magnet original volume, production
Moral character can get a promotion.When the volume that centring magnet 321 hollows out is more than this range, the BL values of magnetic circuit system 3 strongly reduce.
5 space of back cavity increases at this time is not so good as properties of product reducing effect caused by magnetic circuit system BL values reduce to the promotion effect of performance,
General performance reduces for properties of product.Therefore, in above-mentioned technical proposal provided by the utility model, the open volume of centring magnet
It should meet：The open volume of centring magnet 321 is less than or equal to 35% relative to the ratio of 321 volume of centring magnet before trepanning,
It can further control in the range of 5%-30%.
As shown in Figure 1, the housing body unit 101 is rectangular configuration.Using the design of rectangular configuration, sound-producing device it is outer
Portion is simple in structure, and manufacture is simple with mounting process, and convenient for the design of electronic product inner space.
