Kwicandelo lesandi, izithethi zezinye zezixhobo eziphambili eziguqula imiqondiso yombane ibe sisandi. Uhlobo kunye nokuhlelwa kwezithethi kunempembelelo ebalulekileyo ekusebenzeni nasekusebenzeni kakuhle kweenkqubo zesandi. Eli nqaku liza kuhlola iintlobo ezahlukeneyo kunye nokuhlelwa kwezithethi, kunye nokusetyenziswa kwazo kwihlabathi lesandi.

Iintlobo ezisisiseko zezithethi

1. Uphondo olunamandla

Izithethi ezitshintshatshintshayo zezinye zezona ntlobo zixhaphakileyo zezithethi, ezaziwa ngokuba zizithethi zemveli. Zisebenzisa umgaqo wokungenisa isandi ngombane ukuvelisa isandi ngabaqhubi abahamba kwindawo yemagnethi. Izithethi ezitshintshatshintshayo zisetyenziswa kakhulu kwiindawo ezifana neenkqubo zesandi zasekhaya, isandi semoto, kunye nesandi seqonga.

2. Uphondo olunamandla

I-capacitive horn isebenzisa umgaqo we-electric field ukuvelisa isandi, kwaye i-diaphragm yayo ibekwa phakathi kwee-electrode ezimbini. Xa umbane udlula, i-diaphragm iyangcangcazela phantsi kwesenzo se-electric field ukuvelisa isandi. Olu hlobo lwesithethi ludla ngokuba nempendulo ephezulu kakhulu kunye nokusebenza okuneenkcukacha, kwaye lusetyenziswa kakhulu kwiinkqubo ze-audio ezikumgangatho ophezulu.

3. Uphondo olunemagnethi

I-Magnetostrictive horn isebenzisa iimpawu zezinto ze-magnetostrictive ukuvelisa isandi ngokusebenzisa i-magnetic field ukubangela ukuguquguquka okuncinci. Olu hlobo lwe-horn lusetyenziswa rhoqo kwiimeko ezithile zokusetyenziswa, njengonxibelelwano lwe-acoustic olungaphantsi kwamanzi kunye nemifanekiso ye-ultrasound yezonyango.

Ukuhlelwa kwezithethi

1. Uhlu ngokwebhendi yefrikhwensi

-Isithethi se-bass: Isithethi esenzelwe ngokukodwa i-bass enzulu, edla ngokuba noxanduva lokuphinda isandi sivele kwiindlela eziqala kwi-20Hz ukuya kwi-200Hz.

-Isithethi esiphakathi: sinoxanduva lokuphinda sivelise imiqondiso yesandi ngaphakathi koluhlu lwe-200Hz ukuya kwi-2kHz.

-Isithethi esivakala phezulu: sinoxanduva lokuphinda sivelise imiqondiso yesandi kuluhlu lwe-2kHz ukuya kwi-20kHz, esidla ngokusetyenziselwa ukuphinda sivelise izigaba zesandi eziphezulu.

2. Uhlu ngokwenjongo

-Isithethi sasekhaya: senzelwe iinkqubo zesandi sasekhaya, ngokuqhelekileyo silandela ukusebenza kakuhle kwesandi kunye namava amahle esandi.

-Isithethi esiqeqeshiweyo: sisetyenziswa kwimicimbi yobungcali efana nesandi seqonga, ukujonga i-studio yokurekhoda, kunye nokwandiswa kwegumbi leenkomfa, ngokuqhelekileyo ngamandla aphezulu kunye neemfuno zomgangatho wesandi.

-I-horn yemoto: Yenzelwe ngokukodwa iinkqubo zesandi semoto, idla ngokufuna ukuqwalasela izinto ezifana nemida yendawo kunye nemeko-bume ye-acoustic ngaphakathi emotweni.

3. Uhlu ngokweNdlela yokuqhuba

-Isithethi seYunithi: Ukusebenzisa iyunithi yomqhubi omnye ukuvelisa ibhendi yesandi yonke.

-Isithethi seeyunithi ezininzi: Ukusebenzisa iiyunithi ezininzi zokuqhuba ukwabelana ngemisebenzi yokudlala yeebhendi ezahlukeneyo zefrikhwensi, njengoyilo lwesitishi ezimbini, ezintathu, okanye nangaphezulu.

Njengenye yezona zinto ziphambili kwiinkqubo zesandi, izithethi zinokukhetha okwahlukeneyo ngokubhekiselele ekusebenzeni komgangatho wesandi, ukugubungela ibhendi yamaza, ukuphuma kwamandla, kunye neemeko zesicelo. Ukuqonda iintlobo ezahlukeneyo kunye nokuhlelwa kwezithethi kunokunceda abasebenzisi ukuba bakhethe ngcono izixhobo zesandi ezifanela iimfuno zabo, ngaloo ndlela bafumane amava angcono esandi. Ngenkqubela phambili eqhubekayo kunye nokuveliswa kwetekhnoloji, uphuhliso lwezithethi luya kuqhubeka nokuqhuba uphuhliso kunye nenkqubela phambili yentsimi yesandi.
