I-Sonos Play: Impendulo ye-Frequency 1
Impendulo yemvamisa ye-Play: 1 ku-axis, imitha eli-1 phambi kwe-tweeter, iboniswa ku-trace blue. Ukusabela okulinganiselwe kwindwangu yokulalela e-± 30 ° enezingqimba kuboniswa ku-trace eluhlaza. Ngokuvamile, ngesilinganiso sempendulo yesiphakamiso sesikhulumi, ufuna umugqa ohlaza okwesibhakabhaka (on-axis) ukuba ube flat ngangokunokwenzeka, futhi impendulo eluhlaza (esiphezulu) ukusondela kakhulu flat, mhlawumbe ngokunciphisa kancane in impendulo eguquguqukayo.
Lokhu kusebenza ukuthi umklami we-$ 3,000 / isikhulumi sezinhlangothi ezimbili angaziqhenya. I-axis, ilinganisa ± 2.7 dB. Elinganiselwe kuwo wonke iwindi lokulalela, kungu-± 2.8 dB. Lokhu kusho ukuthi ukusebenza kwe-axis ne-off-axis kokubili kuhle kakhulu nokuthi i-Play: 1 kufanele ikhale kahle kakhulu kungakhathaliseki ukuthi uyibeka kuphi egumbini.
Ungabona ukujula okuphansi ukusuka emafenjini aphansi ngakwesobunxele kuya kumazinga aphezulu ngakwesokudla, kodwa ukuqagela ukuthi lezi zinjiniyela ze-Sonos zenza lokhu ukuze igumbi lizwakale ligcwele. Kuyinto eyaziwa kakhulu (nakuba ingaziwa ngokwanele!) Isimiso se-psychoacoustic esivame ukuhamba kancane emkhiwaneni ongenzi ama-bass amaningi singanika ukulinganisela okungokwemvelo okubonakalayo kwe-tonal.
Lokhu kuwumphumela wokusebenzisa i-midrange / woofer engu-3.5 intshi, ene-dispersion enkulu kakhulu ngenxa yobukhulu bayo; ukubeka i-tweeter eduze kakhulu phakathi kwe-middle / woofer, ukunciphisa ukuphazamiseka phakathi kwabashayeli ababili; futhi (ngicabanga) ukusetshenziswa kwezibalo ezikhululekile zokulinganisa usebenzisa i-chip ye-digital signal protocol (DSP). Kuyinto ngokucophelela ukucwaninga kwamacala ukuthi umkhiqizo onjengawo kufanele uklanyelwe kanjani.
Impendulo ye--3 dB ye-Play: 1 yi-88 Hz, enhle kakhulu isikhulumi lokhu okuncane, futhi kufaniswa nalokho engikulinganisile kusuka kubaningi bezingqayizivele ezincane, ngithi, ama-woofers angu-4.5-intshi. I-Sonos kubonakala sengathi ibeke umsebenzi omningi ukuze uthole i-woofer encane engama-3.5-intshi ukudlala kakhulu-ngicabanga ngokuyinika ukuhamba okuningi, noma ibanga lokuhamba ngaphambili, elivumela ukuba liqhube umoya futhi lenze amabhasi amaningi.
Ngiphinde ngenza ukuhlolwa kwami kwe-MCmäxxx, i-"Kickstart My Heart" yaseMötley Crüe ngokuzwakalayo njengoba i-unit ingadlala ngaphandle kokuphazamiseka okukhulu (okuyi-case ye-Play: 1 yayiphezulu), bese kulinganisa ukukhishwa kwemitha engama-1. Ngineminyaka engu-95 ye-DBC, engalinganiswa nalokho engikulinganisele kusuka kuma-AirPlay amaningi nakakhulu ama-Bluetooth. I-Play: 1 ngokuqinisekile idlala kakhulu ngokwanele ukuze igcwalise cishe noma yiliphi ihhovisi lasekhaya noma ikamelo lokulala. Kulungile, mhlawumbe hhayi ekamelweni lika-Oprah. Kodwa uthola umqondo.
Ngendlela, ngenza lezi zilinganiso nge-analyzer ye-Clio 10 FW ne-Clio MIC-01 ebangeni elingu-1 imitha. Izindlela ezingaphezu kuka-300 Hz zenziwe ngokusebenzisa inqubo ye-quasi-anechoic ukususa ukuboniswa kwemisindo emvelweni ozungezile. Impendulo engezansi i-300 Hz ilinganiselwe isebenzisa imigwaqo yasemhlabathini, ne-mic emkhatsini wamamitha ayi-1. Imiphumela engaphezulu kuka-300 Hz ifakwe ku-octave ye-1/12, imiphumela engezansi ku-300 Hz ifakwe ku-octave ka-1/6. Izindlela zithathwe ezingeni lika-80 dB ku-1 kHz / 1 imitha (lokho engikujwayele ukukwenza kumikhiqizo emincane yomsindo), bese kufakwe kwisilinganiso se-0 dB ku-1 kHz yale shadi.
Ngokuvamile, izilinganiso zezikhulumi ezingenantambo - noma yiziphi izikhulumi ezincane, empeleni - zingavamile ukuba ngcono kunalokhu.
