Description
次のように、可能な限り互いに等しい大きさで抵抗を選択することも可能である。
当然、これらの方式を遵守すること、あるいは抵抗を互いに並列でのみ配設することも必要でなく、前記抵抗は、当業者が本発明およびそれぞれの応用例を認識して簡単に設計できる正規の回路網を形成することができる。
2 マイクロホンカプセル
3 増幅器
6 抵抗回路網
Claims (5)
- マイクロホンカプセル(2)と増幅器(3)とを備え、狭い境界で与えられた感度を有するマイクロホン(1)を製造するための方法であって、
前記増幅器(3)が、受動素子として、好ましくは抵抗(Ri)の回路網(6)を備え、
前記マイクロホン(1)の感度が測定され、
次いで前記受動素子が非導通化され、好ましくはレーザ光線により使用不能に破壊され、
前記受動素子の非導通化により、マイクロホン(1)の感度が所望の領域にあるように、前記増幅器(3)の増幅度が変更される、ことを特徴とする方法。 - 前記受動素子の非導通化が、その電気配線が使用不能にされることで行われることを特徴とする請求項1に記載の方法。
- マイクロホンカプセル(2)と増幅器(3)とを備える、狭い境界で与えられた感度を有するマイクロホン(1)において、増幅器(3)に、受動素子、好ましくは抵抗(Ri)の回路網(6)が割り当てられ、前記受動素子の少なくとも1つが非導通化、好ましくは使用不能化されることを特徴とするマイクロホン。
- 前記受動素子の非導通化が、その電気配線の使用不能化によって行われることを特徴とする、請求項3に記載のマイクロホン。
- 前記受動素子が、容量および/または誘導素子であることを特徴とする、請求項3または4に記載のマイクロホン。
