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.
