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直接成正比，與回路的直徑成反比例。國際標準(IEC60118—4，BS7594)指出：一個磁場的長期平均輸出功率值應為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，距離地板1．2米時測得的磁場垂直面上的強度。允許在言語中出現達到400mA/m的強度峰值、頻率范圍應當覆蓋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生過多的削峰。根據電磁原理我們可以看到，感應回路線圈并不是在建筑中產生磁場的的一條電線，所有建筑中的電線都會產生磁場，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，可以干擾。在一些體積較小的助聽器中(其線圈亦小)。湖南新傳感器線圈傳感器線圈型號，無錫東英電子有限公司。</p><div

rx線圈104以以下方式被設計：隨著在整個線圈104上掃描金屬目標124，在一個rx線圈(rxsin112)的端子處產生正弦電壓，在另一個rx線圈(rxcos110)的端子處產生余弦電壓。目標相對于rx線圈104的位置調制在rx線圈104的端子處的電壓的幅度和相位。如圖1a所示和上面討論的，發(fā)射器線圈106、接收線圈104和發(fā)射/接收電路102可以被安裝在單個pcb上。此外，pcb可以被定位成使得金屬目標124被定位在接收線圈104上方并且與接收線圈104間隔開特定間隔，即氣隙(ag)。金屬目標124相對于其上安裝接收線圈104和發(fā)射器線圈106的pcb的位置可以通過處理由正弦定向線圈112和余弦定向線圈110生成的信號來確定。下面，描述在理論上理想的條件下對金屬目標124相對于接收線圈104的位置的確定。在圖1b中，金屬目標124位于位置。在該示例中，圖1b和圖2a、圖2b和圖2c描繪線性位置定位器系統的操作。線性定位器和圓形定位器二者的操作原理相同。在下面的討論中，通過提供因線圈110和線圈112和金屬目標124的前緣的位置所引起的關于正弦定向線圈112的正弦操作的角度關系，給出關于余弦定向線圈110和正弦定向線圈112的構造的位置。</p><p> 并且相對于余弦接收線圈定義正弦接收線圈。為了說明的目的，圖13示出對關于圖12所描述的正弦接收線圈的修改。接收線圈(rx)設計可以用雙環(huán)路迭代來定義。初，在步驟1206中，正弦形狀的rx線圈1316(結合參考系1314)沿x方向對稱地部分延伸(如跡線1310所示)，以補償由于目標非理想性引起的磁通泄漏。利用所施加的線圈延伸，在步驟1208中，使用作用在線圈1316所有點上的適當的位移函數，使正弦形線圈1316沿y方向變形，如跡線1312。給定這些設置，在步驟1210中，算法計算通孔的位置。根據在步驟1202中指定的信息并且為了消除先前提到的信號失配，而建立通孔位置1308。每當一個線圈中的通孔比另一個線圈中的通孔多或通孔以不平衡方式定位(即，不對稱)時，就會出現電壓失配。所導致的電壓失配是當目標移動時正弦信號相對于余弦信號的較大峰峰值幅度(反之亦然)。為了實現減少電壓失配的目標，通孔的設計方式是使sin(1316)rx線圈和cos(1318)rx線圈在pcb底部中的部分的長度相同。此外，通孔相對于設計的對稱中心是對稱的。在步驟1212中，定義正弦接收線圈跡線和余弦接收線圈跡線。在一些實施例中，使用一維模型來定義跡線。在步驟1214中，算法712計算不具有目標時的偏差。傳感器線圈報價，無錫東英電子有限公司。</p><div

使得用于發(fā)射線圈802的跡線中的一些跡線在pcb的一側上，而發(fā)射線圈802的其他跡線在pcb的相反側上。在一些情況下，可以優(yōu)化發(fā)射線圈以使其相對于接收線圈盡可能對稱，同時小化所需空間。圖8a示出通孔814和通孔816，它們允許將發(fā)射線圈802的跡線連接在pcb的側面之間。如圖8a和圖8b進一步所示，接收線圈包括余弦定向線圈804和正弦定向線圈806。余弦定向線圈804包括通孔818，其允許余弦定向線圈804的導線跡線從pcb的一側過渡到另一側。類似地，正弦定向線圈806包括通孔820，其允許在pcb的側面之間過渡正弦定向線圈806的布線。線圈布局800中包括的另一個特征是阱808、810和812的增加，這些阱進一步補償由發(fā)射線圈802生成的場的不均勻性以及由該不均勻性生成的所得偏移誤差。如線圈設計800中所示，提供阱808和阱810來調整正弦定向線圈804，并設置阱812來調整余弦定向線圈806。此外，可以提供通孔822和通孔824，使得阱808和阱812的跡線可以分別在pcb的任一側上。阱808、阱810和阱812可以例如補償由于發(fā)射線圈802生成的場中的不均勻性而引起的接收線圈804和接收線圈806中的偏差。圖9a、圖9b和圖9c示出根據本發(fā)明的一些實施例的另一種線圈設計。塑封傳感器線圈，無錫東英電子有限公司。增強傳感器線圈廠家拿貨價格</p><p
