Being placed for 1 hours at
+25℃, speaker shall be
measured. No obstacle to
be harmful to normal
operation; damages,
cracks, rusts, etc.
Should not be audible at
1.1V sine wave between
Fo ~7KHz. Fo should
meet initial one. S.P.L.
deviation of unit should be
within ±3dB.
經測試後,靜置於+25℃
（室溫）環境中 1 小時後,測
試後無任何障礙防礙正常操
作.且在輸入 1.1V 正弦波從
Fo 到 7KHz 之間無異常
音.Fo 與原規格值相同, 輸
出音壓變化量在±3dB 內.
