Chii chinonzi acoustic feedback?

Mu sound reinforcement system, kana vhoriyamu yemaikorofoni yakawedzera zvakanyanya, inzwi rinobva kumutauriri richaendeswa kukurira kunokonzerwa nemaikorofoni.Ichi chiitiko iacoustic mhinduro.Kuvapo kweacoustic mhindurokwete kungoparadza kunaka kwezwi, asiwo kunoderedza kuwedzera kwezwi remakrofoni, kuitira kuti inzwi rakatorwa nemakrofoni harigoni kudhindwa zvakanaka;iyo yakadzika acoustic mhinduro ichaitawo kuti sisitimu sigini ive yakasimba zvakanyanya, nekudaro ichipisa simba amplifier kana mutauri (kazhinji kupisa.mutauri tweeter), zvichikonzera kurasikirwa.Naizvozvo, kana chiitiko chemhinduro chinonzwika chikaitika muhurongwa hwekusimbisa inzwi, tinofanira kutsvaga nzira dzekuchimisa, zvikasadaro, zvinozokonzera kukuvadza kusingaperi.

Chii chikonzero cheacoustic mhinduro?

Pane zvikonzero zvakawanda zveacoustic mhinduro, chinonyanya kukosha kuve dhizaini isina musoro yenzvimbo yemukati yekusimbisa ruzha, inoteverwa nehurongwa husina musoro hwevatauri, uye kusagadzirisa zvakanaka kwemidziyo yekuteerera uye.audio system.Kunyanya, inosanganisira zvinotevera zvinhu zvina:

 

(1) The maikorofoniinoiswa zvakananga munzvimbo yemwaranzi yemukurukuri, uye akisi yaro inopindirana zvakananga nemutauri.

 

(2) Chiitiko chekuratidzira chinonzwika chakakomba munzvimbo inosimbisa ruzha, uye zvakatenderedza uye sirin'i hazvina kushongedzwa nezvinhu zvinotora ruzha.

 

(3) Kufananidza zvisina kufanira pakati pemidziyo yekuteerera, yakakomba chiratidzo chekuratidzira, chaiyo welding yemitsara yekubatanidza, uye nzvimbo dzekusangana kana masaini ekurira achiyerera.

 

(4) Mimwe yemidziyo yekuteerera iri munzvimbo yakaoma yekushanda, uye oscillation inoitika kana chiratidzo chekurira chakakura.

 

Acoustic mhinduro ndiro dambudziko rinonyanya kunetsa muhoro yekusimbisa inzwi.Zvingave zviri mumitambo yemitambo, nzvimbo dzemitambo kana mahoro ekutamba, kana mhinduro yeacoustic yaitika, haingoparadzi iyo yakajairika yekushanda kwese system system, kuparadza ruzha rwemhando, asiwo kuparadzamusangano, maitiro ekuita.Naizvozvo, kudzvinyirirwa kweacoustic mhinduro inyaya yakakosha zvakanyanya iyo inofanirwa kutariswa mukati mekugadzirisa uye kushandiswa kwemasisitimu ekusimbisa inzwi.Vashandi veaudio vanofanirwa kunzwisisa acoustic mhinduro uye kuwana nzira iri nani yekunzvenga kana kuderedza kuchema kunokonzerwa acoustic mhinduro.
