hydz 2040mm isithethi semylar esixande

1.UMDA
Olu luhlu lugubungela imveliso yethu yeyunithi yesithethi se-mylar ukuze isetyenziswe kwi-DVD, ifowuni, inkqubo ye-alam kunye nenkqubo yokufowuna.

2.UMbane ANDACOUSTICAL CHARACTERISTIC

2.1.ISANDI SOXINZELELO (SPL)
Inqanaba loxinzelelo oluvakalayo liya kuboniswa ngexabiso eliphakathi kwezo zilinganisiweyo
uluhlu lwamaza obuninzi obuchaziweyo.81±3 dB kwi-1200,1500,1800,2000 Hz kumndilili.
Imeko yomlinganiselo: umlinganiselo wesono utshayelwe kwi-0.1W kwi-axis kwi-0.1M
ISekethe yoMlinganiso: iboniswe kuMfanekiso 2.

2.2.I-RESONANCE FREQUENCY(FO):980±20%Hz kwi-1V.(AKUKHO Baffle)
ISekethe yoMlinganiselo:Iboniswe kuMfanekiso.2.

2.3.UKUNIKEZELWA INGQIQO: 8±20% Ω (ku-1KHz, 1V)
Umlinganiselo wemeko: impendulo yokuphazamiseka ilinganiswa nesithethi seMylar.
ISekethe yoMlinganiso: iboniswe kuMfanekiso 2.

2.4.UHLELO LWEFREQUENCY: Fo~20KHz (Ukutenxa 10dB ukusuka kumndilili we-SPL)
Ijika leempendulo zarhoqo:Iboniswe kwiFig.3.Whit IEC Baffle plate.
ISekethe yoMlinganiselo weMpendulo rhoqo: Iboniswe kwiFig.2.

2.5.AMANDLA OKUQHUBEKA OKUQHUBEKAYO: 2.0W

2.6.AMANDLA OKUFAKAYO OMKHULU (IXESHA ELIFUTSHANE): 2.0W
Uvavanyo luya kwenziwa kusetyenziswa i-IEC yokucoca ngomthombo wengxolo emhlophe ngomzuzu omnye
kungabikho kuthotywa kwentsebenzo.

2.7.IYONKE I-HARMONIC DISTORTION: Ngaphantsi kwe-5% kwi-1KHz, 2.0W
ISekethe yoMlinganiselo:Iboniswe kuMfanekiso.2.

2.8.UKUSEBENZA: Kufuneka ibe yesiqhelo kwi-sine wave kunye nomthombo wenkqubo 2.0W.

2.9.POLARITY: Xa i-DC yangoku isetyenziswa kwi-terminal ephawulweyo(+),
I-diaphragm iya phambili.Ukuphawula:

2.10.UKUFUMANA NGESANDI ESINGCWELE:
I-Buzz, i-Rattle, njl.
