After take analyzed deeply for the opened magnet circuit with FEMM (Finite Element Method Magnetics) we find out the field distributing that is separated into three sections . One is the main area what we called as positive field section. Beside the main field there are tow areas that are called the inverted field sections. Loudspeaker arise a very serious distortion when the voice coil moving into inverted field areas. The direction of induced current in the coil part of entered inverted field area is same with the current driving into loudspeaker so that total currents increas largely and heat increase rapidly. With more coils moving into inverted area the voice coil will take on negative inductance properties. It is the main reason that voice coil is burned by heating with increasing current due to arise negative inductance. So opened magnetic circuit is not suitable for the woofers in which the voice coil have wider displacement range. When using this kind magnetic circuit design, the voice coil moving range should be less than the range of positive field to avoid loudspeaker arise serious distortion and heating. Even though voice coil moving range is in the positive area, loudspeaker will still arise more distortion because the field distribution is very cliffy at tow sides of the positive area and full range of magnetic field distribution is not parallel that will arise distortion. Base on above reasons, opened magnetic circuit is not an ideal magnetic circuit for low-frequency loudspeakers. But it can be used in mid-range or high-frequency productions.
开式磁路是由2片钕铁硼磁铁和主导磁板和导磁垫片组成,我们在实践过程中发现这种磁路结构不适合于低频扬声器的使用,我们通过使用FEMM(Finite Element Method Magnetics)软件包对该磁路进行了分析,该磁路的磁场范围被分成3个区域,其中在主导磁板附近形成一个正向磁场,在正向磁场的两边存在反向的磁场,音圈在工作时有很大一部分进入了反向磁场中,在反向磁场内线圈的感应电流方向与驱动电流方向相同,使得音圈呈现出负感抗特性,由于音圈的负感抗特性引起电流的增加导致音圈发热甚至烧毁,因此在扬声器中使用开式磁路时,音圈的运动范围应控制在正向磁场范围之内,否则音圈运动到反向磁场区域时将会产生很大的失真和发热,即使在设计时已经将音圈的运动范围控制在正向磁场范围之内,由于正向磁场的2个边缘磁场强度衰减太快,同时开式磁路中磁场的分布不是平行的,而是自由发散的分布,这样肯定会导致扬声器的非线性失真,因此我们得到的结论是:开式磁路并不是一个理想的磁路,它不适合于低频扬声器的使用,但它还可以应用于中高频扬声器。

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.
