壽命測試
1.Continuous life test 高溫壽命測試(連續)
48 hours continuous operation at +70℃ with rated voltage applied.
在+70℃環境下,以額定電壓連續操作 48 小時.
2.Intermittent life test 室溫壽命測試(間歇)
A duty cycle of 1 minute on, 1 minutes off, a minimum of 5000 times at room
temp.( +25±2℃)and rated voltage applied.
在室溫下(+25±2℃), 以額定電壓操作, 通電 1分鐘/斷電 1 分鐘,測試
5000 次循環.
Being placed for 4 hours at
+25℃, buzzer shall be
measured. The value of
oscillation frequency/ current
consumption should be in ±10%
compared with initial ones .The
SPL should be in ±10dB
compared with initial one.
經測試後, 靜置於+25℃（室溫）
環境中 4 小時後,諧振頻率與消耗
電流變化量須在±10%內. 輸出音
壓變化量須在±10dB 內.
