1.ISIKOPE
Lokhu kushiwo kuhlanganisa umkhiqizo wethu weyunithi yesipikha se-mylar esizosetshenziswa ku-DVD, ucingo, isistimu ye-alamu kanye nesistimu yokushaya ucingo.
2.IZIMALI ZOKUGCINA KAgesi kanye ne-ACOUSTICAL
2.1.IZINGA LOMSINDO WOMSINDO (SPL)
Izinga lokucindezela komsindo lizoboniswa ngenani elimaphakathi lalawo akalwa ku-
Ibanga lemvamisa elicacisiwe.81±3dB ku-1200,1500,1800,2000 Hz ngokwesilinganiso.
I-Measure Condition: Isilinganiso sokushanelwa kwesono ku-0.1W ku-eksisi engu-0.1M
Umjikelezo Wokulinganisa: uboniswe ku-Fig. 2.
2.2.I-RESONANCE FREQUENCY(FO):980±20%Hz ku-1V.(NO Baffle)
Umjikelezo Wokulinganisa:Kuboniswe ku-Fig.2.
2.3.UKUTHIMBA OKULINGANISWE: 8±20% Ω (ku-1KHz, 1V)
I-Measure Condition: impendulo ye-impedance ilinganiswa nesipika se-Mylar.
Umjikelezo Wokulinganisa: uboniswe ku-Fig. 2.
2.4.IFREQUENCY RANGE: Fo~20KHz (Ukuchezuka ngo-10dB ukusuka ku-SPL evamile)
Ijika Lempendulo Yemvamisa:Kuboniswe ku-Fig.3.Whit IEC Baffle plate.
Isiyingi Sokulinganisa Ukusabela Imvamisa: Siboniswa ku-Fig.2.
2.5.AMANDLA OKUFAKA OKULINGANISWE (IYAQHUBEKA): 2.0W
2.6.AMANDLA OKUFAKA AMANINGI (Isikhathi Esifushane): 2.0W
Ukuhlola kuzokwenziwa kusetshenziswa isihlungi se-IEC esinomthombo womsindo omhlophe iminithi elingu-1
ngaphandle kokwehlisa izinga lokusebenza.
2.7.I-TOTAL HARMONIC DISTORTION: Ngaphansi kuka-5% ku-1KHz, 2.0W
Umjikelezo Wokulinganisa:Kuboniswe ku-Fig.2.
2.8.UKUSEBENZA: Kumele kube okujwayelekile ku-sine wave kanye nomthombo wohlelo 2.0W.
2.9.POLARITY: Uma i-DC yamanje isetshenziswa kutheminali ephawulwe(+),
I-diaphragm izoqhubekela phambili.Ukumaka:
2.10.UKUTHOLA UMSINDO OHLANZEKILE:
I-Buzz, Rattle, njll Akumele izwakale ku-4 VRMS sine wave kusuka ku-Fo ~ 10KHz.
