可以使用數(shù)百甚至數(shù)千次仿真。因此，存在一些模型簡化，這盡管基本上不影響仿真的準確性，但可以提高速度。例如，如果每次仿真需要10秒鐘來完成，山東空調(diào)傳感器線圈，則使用100次迭代的優(yōu)化可能需要16分鐘。然而，如果每次仿真需要10分鐘完成，則同一優(yōu)化可能需要16個小時來完成。在一些實施例中使用的有效簡化是用一維導(dǎo)線模型來表示用于形成發(fā)射線圈和線圈的導(dǎo)電跡線。在與一維導(dǎo)線模型偏離嚴重的情況下，山東空調(diào)傳感器線圈，考慮一個具有35μm的高度和。該矩形跡線可以由例如銅的任何非磁性導(dǎo)電材料形成。其他金屬也可以用來形成跡線，但銅更為典型。對于厚度為趨膚深度的大約兩倍的跡線部分，矩形跡線中流動的電流的電流密度可以是非常均勻的。對于銅，山東空調(diào)傳感器線圈，在5mhz的頻率下的趨膚深度為30μm。因此，對于上述基準矩形跡線，跡線內(nèi)的電流密度將是基本上均勻的。圖10b示出由承載電流的一維導(dǎo)線1020生成的場。如果在兩個結(jié)構(gòu)中流動的電流相同，則由導(dǎo)線1020或由一定直徑的直的圓柱體生成的場沒有差異。然而，圖10c示出在基準跡線1022周圍生成的場，基準跡線1022是上述由銅形成的并且具有35μm的高度和。如圖10c所示，即使在小于1mm的短距離處，該場看起來也與圖10b中的由導(dǎo)線1020所生成的場相同。塑封傳感器線圈，無錫東英電子有限公司。山東空調(diào)傳感器線圈</p><div

圖10f示出正在算法704中進行仿真的位置定位系統(tǒng)設(shè)計中的線圈1028和線圈1026上方的金屬目標1204的定位。為了討論的目的，圖10f示出圖8a和圖8b所示的線圈設(shè)計800的示例，其中線圈1028和線圈1026分別與線圈804和線圈806的跡線的一維近似相對應(yīng)。為了簡化圖示，在圖10f中未示出發(fā)射線圈802，但是發(fā)射線圈802的跡線也通過一維導(dǎo)線跡線近似。在仿真了來自位置定位系統(tǒng)800的目標線圈802的電磁場之后，然后在圖10a所示的算法704的示例的步驟1008中，仿真金屬目標1024的渦電流，并且確定從那些渦電流產(chǎn)生的電磁場。在一些實施例中，金屬目標1024中的感應(yīng)渦電流是通過原始邊界積分公式來計算的。金屬目標1024通?？梢员唤楸〗饘倨Ｍǔ?，金屬目標1024很薄，為35μm至70μm，而橫向尺寸通常以毫米進行測量。如上文關(guān)于導(dǎo)線跡線所討論的，當導(dǎo)體具有小于在特定工作頻率下磁場的穿透深度的大約兩倍的厚度時，感應(yīng)電流密度在整個層厚度上基本上是均勻的。因此，可以將金屬目標1024的細導(dǎo)體建模為感應(yīng)渦電流與該表面相切的表面。如果不是這種情況，則可以使用類似于以下中提供的計算上代價更高的體積積分公式或有限元建模來對目標進行建模：bettini，m.、passarotto，艮、specogna。山東空調(diào)傳感器線圈換向傳感器線圈，無錫東英電子有限公司。</p><div

也就是磁力線的方向)是環(huán)繞著電流的一些閉合曲線，磁力線和由此產(chǎn)生的磁通量(可以被看做磁力的流動)，是一些位于垂直于電流的平面上的同心圓，是圍繞產(chǎn)生它們的電流呈環(huán)形流動的。靠近電流的地方磁場較強，離電流遠的地方，磁力和磁流就越弱。磁力線方向與電流方向的關(guān)系可以用右手螺旋法則來判定。將右手握住導(dǎo)線，拇指伸直，如果拇指電流方向，彎曲的手指磁場環(huán)繞方向。當線圈安裝在地板上，而助聽器佩戴者是坐著或站著時，在回路中，在頭部高度的磁力線以水平為主。這樣，在頭部高度，磁場的垂直部分就有一個近乎持續(xù)的量幾乎覆蓋整個房間。剛進人回路處是個例外，那里，除了垂直部分很弱外，整個磁場都較強。以上特性很重要，因為助聽器中的接受線圈的安裝是垂直的，它*能拾取磁場的垂直部分。這里已經(jīng)討論了沿著回路一個方向的電流，然而聲音是音頻信號，相對應(yīng)于原始聲波中的正壓和負壓，方向每秒會倒轉(zhuǎn)許多次。因此，循環(huán)的磁場每秒也會倒轉(zhuǎn)許多次。事實上，根據(jù)電磁場理論，正是持續(xù)改變的磁流使拾音線圈感知，產(chǎn)生一個音頻電流(地球的磁場不會影響線圈，正是因為地球磁場有持續(xù)的力量和方向)。。</p><p>

如果導(dǎo)線通過的電流是固定不變的，即直流電流，則產(chǎn)生的磁場也是恒定的。而當一個閉合回路中的電流發(fā)生變化時，隨著電流的變化，電流產(chǎn)生的磁場也在變化。如果導(dǎo)線通過語音電流，則產(chǎn)生的磁場也隨語音的變化而變化。這種變化的磁場將在它附近的其他回路中產(chǎn)生感應(yīng)電流。如果把一個線圈回路放置在磁場中，磁力線通過線圈回路時，線圈回路有電流產(chǎn)生。如磁場是由語音信號所產(chǎn)生，那么在此磁場中線圈感應(yīng)的電流則是語音電流。電場轉(zhuǎn)變磁場，磁場轉(zhuǎn)變電場的過程，是電磁感應(yīng)基本原理的實際應(yīng)用。由此我們知道，磁感應(yīng)線圈助聽系統(tǒng)信號發(fā)送與接收的過程是，將放大的音頻信號電流，通過長直導(dǎo)線形成隨音頻變化的交變磁場，由接收耳機中的線圈感應(yīng)出微弱音頻電流，經(jīng)放大后，耳機又將其恢復(fù)成語音信號。來自錄音機、收音機、電視機或教師的聲音經(jīng)麥克風(fēng)、放大器、調(diào)頻部件以交流電的形式直接傳遞到線圈內(nèi)，電流在線圈周圍產(chǎn)生了一個電磁場，這種帶有聲音信號的電磁波可以在空間傳播并為助聽器上的拾音線圈(telecoil)所接收。在拾音線圈里電磁波又轉(zhuǎn)換為音頻電流，電流再經(jīng)過助聽器的放大處理，還原成聲音信號。山東空調(diào)傳感器線圈</p><p
