Itekhnoloji kunye nokuveliswa kweenkqubo zesithethi ziqhubela phambili uphuhliso olugudileyo kule minyaka.Kwiminyaka yakutshanje, imeko itshintshile, kwaye iinkqubo zesithethi ezihambelanayo ziye zavela kwimidlalo emininzi emikhulu kunye nemidlalo yehlabathi.
Isixokelelwano sesithethi soluhlu lweengcingo sikwabizwa ngokuba sisithethi esidibeneyo somgca.Izithethi ezininzi zinokudityaniswa zibe liqela lesithethi kunye ne-amplitude efanayo kunye nesigaba (uluhlu) olubizwa ngokuba sisithethi soluhlu.
Uluhlu lwemigca luseti yeeyunithi zemitha ezicwangciswe ngokuthe tye, imigca esondeleleneyo kunye ne-amplitude efanayo nesigaba.
Uluhlu lwezithethi zomgcazisetyenziswa kakhulu, ezinje ngezokhenketho, iikonsathi, iithiyetha, izindlu zeopera njalo njalo.Iyakwazi ukukhanya kwiinkqubo ezahlukeneyo zobunjineli kunye nokusebenza kweselula.
I-directivity ye-line array speaker yi-beam emxinwa kwi-plane ethe nkqo ye-axis ephambili, kunye ne-superposition yamandla inokukhanya ukusuka kumgama omde.Ngelixa isiphelo esisezantsi senxalenye egobileyo yekholamu yomgca igubungela indawo ekufutshane, isenza i-proximal ukuya kugutyulo olude.
Umahluko phakathi kwenkqubo yesithethi soluhlu kunye nesandi esiqhelekileyo
1. Ngokwembono yodidi, isithethi somgca sisithethi esikude, ngelixa isithethi esiqhelekileyo sisisithethi esifutshane.
I-2, ukusuka kwimbono yeziganeko ezisebenzayo, isandi sezithethi ze-line linear, zifanelekile ngaphandle kwesandi esikhulu sokwandiswa kweqela, ngelixa izithethi eziqhelekileyo zifanelekile kwimibhiyozo yangaphakathi okanye imisebenzi yasekhaya.
Ngokombono wokugubungela isandi, iizithethi zoluhlu lwemigcaube nesandi esibanzi, kwaye izithethi ezininzi zinokudityaniswa zibe liqela lezithethi ezine-amplitude efanayo kunye nesigaba.
