二)磁場的強度在近房間中心的磁場強度與回路中電流的大小和回路數(shù)直接成正比，與回路的直徑成反比例。國際標(biāo)準(zhǔn)(IEC60118—4，河南傳感器線圈優(yōu)勢，BS7594)指出：一個磁場的長期平均輸出功率值應(yīng)為100mA/m(指每米毫安培)。不得低于70mA/m或高于140mA/m。該值是在回路內(nèi)，距離地板1．2米時測得的磁場垂直面上的強度。允許在言語中出現(xiàn)達到400mA/m的強度峰值、頻率范圍應(yīng)當(dāng)覆蓋100Hz—5kHz。在回路中心的直徑a米，有n周圍繞的回路其磁場強度可以用下式計算：H是磁場的強度，用每米毫安培表示，I是電流值的均方根，用安培表示、對一個正方形的回路，大小用a米表示，其磁場強度要比計算的值少10%。如果磁場的長期平均輸出功率強度要達到100mA/m，則回路輸出的值至少要在400mA/m(好560mA/m)，這樣可以避免在更大強度的言語聲音中產(chǎn)生過多的削峰。根據(jù)電磁原理我們可以看到，感應(yīng)回路線圈并不是在建筑中產(chǎn)生磁場的的一條電線，所有建筑中的電線都會產(chǎn)生磁場，因此，助聽器不僅能收到語音信號，也可以接收到其他磁場信號，如50Hz的電源電壓信號等。在布線的時候要充分考慮到干擾源的問題。如果音頻磁場太弱，信噪比就不夠大。提高信號發(fā)射功率，河南傳感器線圈優(yōu)勢，可以干擾。在一些體積較小的助聽器中(其線圈亦小)，河南傳感器線圈優(yōu)勢。微型傳感器線圈，無錫東英電子有限公司。河南傳感器線圈優(yōu)勢</p><div

電感線圈的敏感性要通過使用單獨的前置放大線圈獲得。當(dāng)然，對于弱的磁場，使用者也可以通過增加音量來彌補。但是這樣不太方便，尤其是需要經(jīng)常切換麥克風(fēng)擋和電感擋時。此外，這需要助聽器有足夠的音量保留，同時在獲得足夠的增益時不會引起嘯叫。在電感位置，如果增益太大，也會引起嘯叫。就像聲波從授話器漏回麥克風(fēng)會引起反饋一樣，磁場引起的嘯叫也是從授話器漏回到電感線圈引起的。(三)感應(yīng)線圈回路的頻率響應(yīng)助聽器通過麥克風(fēng)接收到的頻率響應(yīng)與通過感應(yīng)線圈得到的頻率響應(yīng)之間存在著匹配的問題。助聽器的響度通常都通過仔細(xì)的調(diào)整，以適合佩戴者、假沒助聽器在聲音輸入是70dBSPL時和磁場強度是100mA/m時的輸出功率是一樣的話，助聽器佩戴者就可以方便地從麥克風(fēng)擋切換到電感擋，而無需改變音量。然而感應(yīng)線圈回路和助聽器電感系統(tǒng)的頻響有時仍不能令人滿意。但回路響應(yīng)和助聽器電感響應(yīng)結(jié)合時產(chǎn)生的聲音，不能與原來的聲音響應(yīng)區(qū)別太大。只有一個例外，即500Hz以下頻率聲音的減弱，在某些情況下對某些人可能是有利的，因為這個頻率范圍是磁場干擾容易發(fā)生的。但這也是對重度聽力損失的人很重要的頻率范圍。好在多記憶助聽器可以分開調(diào)整麥克風(fēng)和電感的響應(yīng)。河南傳感器線圈優(yōu)勢外殼傳感器線圈，無錫東英電子有限公司。</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(biāo)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(biāo)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(biāo)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(biāo)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(biāo)1024通常可以被建模為薄金屬片。通常，金屬目標(biāo)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(dāng)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(biāo)1024的細(xì)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(biāo)進行建模：bettini，m.、passarotto，艮、specogna。</p><p> 金屬目標(biāo)與多個線圈中的每個線圈之間可以是不同的耦合效果。這些和其他因素可能導(dǎo)致位置定位系統(tǒng)的不準(zhǔn)確的結(jié)果。因此，需要開發(fā)更好的設(shè)計傳感器線圈的方法，其為位置感測提供更好的準(zhǔn)確度。技術(shù)實現(xiàn)要素：在一些實施例中，提供了一種線圈設(shè)計系統(tǒng)。具體地，提出一種提供經(jīng)優(yōu)化的位置定位傳感器線圈設(shè)計的方法。該方法包括：接收線圈設(shè)計；利用該線圈設(shè)計對位置確定進行仿真，以形成仿真性能；將仿真響應(yīng)與規(guī)范進行比較以提供比較；以及基于仿真性能和性能規(guī)范之間的比較來修改線圈設(shè)計，以獲得更新的線圈設(shè)計。下文結(jié)合附圖討論這些和其他實施例。附圖說明圖1a和圖1b示出用于確定目標(biāo)的位置的線圈系統(tǒng)。圖2a、圖2b、圖2c、圖2d和圖2e示出在整個線圈系統(tǒng)上掃描金屬目標(biāo)時的線圈的響應(yīng)。圖3a和圖3b示出線圈系統(tǒng)中的印刷電路板上的接收線圈的配置。圖3c示出由線圈系統(tǒng)中的發(fā)射線圈生成的電磁場的非均一性。圖3d和圖3e示出由線圈系統(tǒng)中的線圈測量的場的差異。圖4a示出測試位置定位系統(tǒng)的準(zhǔn)確性的測試設(shè)備的框圖。圖4b示出諸如圖4a所示的測試設(shè)備。圖4c示出利用圖4b所示的測試設(shè)備來測試位置定位系統(tǒng)?？諝鈧鞲衅骶€圈，無錫東英電子有限公司。</p><div

例如，目標(biāo)的角位置可以被計算為：角位置＝arctan(vsin/vcos)。圖2e示出了這一點，并且示出vcos和vsin的正弦形式以及根據(jù)vcos和vsin的值得出的對金屬目標(biāo)124的位置的確定。在線性位置定位系統(tǒng)中，可以通過知道線圈104的跡線的正弦形式的波長(即，正弦定向線圈112的跡線和余弦定向線圈110的跡線的峰距區(qū)域之間的間隔)，通過角位置來確定線性位置。在角位置定位系統(tǒng)中，正弦定向線圈112和余弦定向線圈110可以被布置為使得該角位置可以等于關(guān)于金屬目標(biāo)124的旋轉(zhuǎn)的金屬目標(biāo)124的實際角位置。重要的是要注意指示位置定位傳感器100的理想操作的以下條件。在那些條件中，發(fā)射器線圈106的形狀不重要，只要其覆蓋放置線圈104的區(qū)域即可。此外，線圈104的形狀等于完美的幾何重疊的正弦和余弦。另外，金屬目標(biāo)124的形狀對工作原理沒有影響，只要目標(biāo)的區(qū)域覆蓋線圈104的總區(qū)域的一部分即可。理想的一組線圈和理想的金屬目標(biāo)的這些條件從未被滿足。在實際系統(tǒng)中，情況大不相同。非理想性導(dǎo)致金屬目標(biāo)124的位置的確定的不準(zhǔn)確性。導(dǎo)致位置確定的不正確性的問題包括發(fā)射線圈106中生成的電磁場的不均勻。傳感器線圈線圈，無錫東英電子有限公司。河南傳感器線圈優(yōu)勢</p><p
