1.SCOPE
Iyi dhizaini inovhara chigadzirwa chedu che mylar speaker unit yekushandisa muDVD, runhare, alarm system uye yekufona system.
2.ELECTRICAL ANDACOUSTICAL CHARACTERISTIC
2.1.SOUND PRESSURE LEVEL (SPL)
Chiyero chekumanikidza kwenzwi chicharatidzwa nehuwandu hwehuwandu hweavo vakayerwa pa
yakataurwa frequency range.81±3 dB pa 1200,1500,1800,2000 Hz paavhareji.
Measure Mamiriro: chiyero chakatsvaira chivi pa 0.1W pane axis pa 0.1M
Measurement Circuit: inoratidzwa mumufananidzo 2.
2.2.RESONANCE FREQUENCY(FO):980±20%Hz pa1V.(NO Baffle)
Chiyero Denderedzwa:Inoratidzwa muFig.2.
2.3.RATED IMPEDANCE: 8±20% Ω (pa1KHz, 1V)
Measure Mamiriro: iyo impedance mhinduro inoyerwa neMylar speaker.
Measurement Circuit: inoratidzwa mumufananidzo 2.
2.4.FREQUENCY RANGE: Fo~20KHz (Kutsauka 10dB kubva paavhareji SPL)
Frequency Response Curve:Inoratidzwa muFig.3.Whit IEC Baffle plate.
Frequency Response Measurement Circuit: Inoratidzwa muFig.2.
2.5.RATED INPUT SIMBA (CONTINUUM): 2.0W
2.6.MAX INPUT SIMBA (SHORT-TERM): 2.0W
Kuyedzwa kuchaitwa uchishandisa IEC sefa ine chena ruzha sosi kweminiti imwe
pasina kudzikira mukuita.
2.7.ZVOSE HARMONIC DISTORTION: isingasviki 5% pa1KHz, 2.0W
Chiyero Denderedzwa:Inoratidzwa muFig.2.
2.8.OPERATION: Inofanirwa kuve yakajairika kune sine wave uye chirongwa sosi 2.0W.
2.9.POLARITY: Kana yakanaka DC ikozvino yaiswa kune iyo terminal yakanyorwa (+),
Diaphragm ichaenda kumberi.Kumaka:
2.10.PURE SOUND GURECTION:
Buzz, Rattle, etc Haifanire kunzwika pa4 VRMS sine wave kubva kuFo ~ 10KHz.
