壽命測試
1.Continuous life test 高溫壽命測試(連續)
48 hours continuous operation at +55℃ with DC 12V applied.
在+55℃環境下,以DC 12V 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 5,000 times at room
temp. ( +25±2℃) and DC12V applied
在室溫下(+25±2℃), 以DC 12V電壓操作, 通電 1 分鐘/斷電 1分鐘,測試
5,000 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.
