Sekoti sa Magnetic ke Eng? Tataiso e Felletseng bakeng sa Baenjiniere le Bareki
Maikutlo a utloahalang ke tlhoko ea bohlokoa ea moralo bakeng sa lisebelisoa tsa elektroniki ho pholletsa le li-dashboard tsa likoloi, tlhahlobo ea bongaka, lisebelisoa tsa elektroniki tsa bareki le liphanele tsa alamo tsa indasteri. Har'a likarolo tsa motlakase le molumo, li-buzzer tsa makenete e ntse e le tharollo e ka sehloohong bakeng sa lihlopha tsa boenjiniere tse hlokang tlhahiso e tšepahalang ea molumo ka li-voltage tse tlase tsa ts'ebetso le mehato e nyane ea PCB.
Hore na o rala kopano ya PCB e nang le bophahamo bo hodimo kapa o batla diphetoho tsa ho kenya bakeng sa mohala o seng o ntse o le teng wa tlhahiso, ho utlwisisa fisiks ya magnetic buzzer, maemo a ho kganna, le diparamente tsa tekheniki ho netefatsa tlhahiso e ntle ya kgatello ya modumo ntle le kgatello ya matla e sa hlokahaleng.
1. Sesebediswa sa makenete se sebetsa jwang?
Buzzer ea makenete e sebetsa ho latela melao-motheo ea induction ea motlakase. Ka hare ho ntlo ea polasetiki, likarolo tse 'ne tsa mantlha tsa kahare li khanna tlhahiso ea molumo:
Ha lets'oao la motlakase le fapanyetsanang (hangata leqhubu la sekwere) le feta ka har'a coil, le hlahisa matla a makenete a feto-fetohang. Tšimo ena e matla e hohela le ho lokolla diaphragm ea tšepe ka mokhoa o fapaneng maqhubung a ho khanna - hangata ho potoloha 2,000 Hz ho isa ho 2,700 Hz. Diaphragm e thothomelang e hatella ka potlako limolek'hule tse potolohileng tsa moea, e fetola matla a motlakase hore e be melumo e hlakileng le e hlakileng ea molumo.
2. Li-buzzers tsa makenete khahlanong le tsa piezoelectric: Liphapang tsa bohlokoa
Ho kgetha pakeng tsa theknoloji ya makenete le piezo ho itshetlehile haholo-holo hodima motlakase o fumanehang wa potoloho, maqhubu a shebilweng, le dithibelo tsa sebaka botong ya hao.
| Paramethara ea Tekheniki | Li-buzzers tsa makenete | Li-buzzers tsa Piezoelectric |
|---|---|---|
| Mefuta ea Voltage e sebetsang | 1.5V ho isa ho 12V DC (E loketse lipotoloho tse nang le motlakase o tlase). | 3V ho isa ho 30V+ DC (E hloka di-voltage tse phahameng tsa drive). |
| Tšebeliso ea Hona Joale | E phahameng (~30mA ho isa ho 100mA). | E tlase haholo (~2mA ho isa ho 10mA). |
| Maqhubu a Resonant | Tlase (~2,000 Hz – 2,700 Hz, molumo o mofuthu oa molumo). | E phahameng (~3,000 Hz – 4,000 Hz, molumo o bohale le o phahameng). |
| Bohato ba maoto / Profaele | Bolelele bo bonyenyane, dikgetho tse nyane tsa bophara. | Bophara bo pharaletseng, kaho ea diski e bataletseng. |
3. Transducer (Drive ea Kantle) khahlanong le Sesupo (Drive ea Ka Hare)
Ha o hlahloba maqephe a data a likarolo, ela hloko haholo hore na karolo eo e arotsoe e le transducer ea makenete kapa sesupo sa ho kganna ka hare:
4. Liparamente tsa Bohlokoa bakeng sa Boenjiniere ba PCB le Theko
Ho qoba ho sotha molumo kapa ho senyeha ha likarolo pele ho nako, hlahloba liparamente tsena nakong ea teko ea mohlala:
Litharollo tse Tšepahalang tsa Acoustic ka HYDZ Electronics
Ho fumana likarolo tse tsitsitseng tsa motlakase le molumo ho hloka ho nepahala ho tsitsitseng ha ho kobeha ha khoele le ho tšoarella ha diaphragm. Lisebelisoa tsa Elektroniki tsa HYDZ (Jiangsu Huayu Electronics Co., Ltd.) ke moetsi ea tsebahalang ea ikhethang ka likarolo tsa molumo o monyenyane bakeng sa mebaraka ea machaba.
