Igama lebrashi yamazinyo ye-sonic lithatyathwe kwibrashi yamazinyo yokuqala, uSonicare. Ngapha koko, i-Sonicare luphawu kuphela, kwaye ayinanto yakwenza noSonic. Ngokubanzi, ibhrashi yamazinyo ye-sonic ikwisantya sokungcangcazela samaxesha angama-31,000/min okanye ngaphezulu. Nangona kunjalo, emva kwenguqulelo, andazi ukuba iyalahlekisa na. Abathengi abaninzi abaqondi kakuhle ukuba zonke iibrashi zamazinyo zombane ezenza izandi xa iindlebe zomntu zinokuva ziibrashi zamazinyo ze-sonic, okanye zisebenzise umgaqo wamaza omsindo ukuxubha amazinyo.
Ibrashi yamazinyo yokwenyani ifuna ukungcangcazela rhoqo ukuya kuthi ga kwiintshukumo ezingaphezulu kwama-50000 ngomzuzu.
Ibhrashi yamazinyo kaHilton yaBantwana yeSonic
Ngapha koko, uluhlu oluphindaphindiweyo lokuva komntu malunga ne-20 ~ 20000Hz, kwaye isantya sebrashi yamazinyo ye-sonic ngama-31000 amaxesha / ngomzuzu aguqulwa abe yi-frequency ye-31000/60/2≈258Hz (isizathu sokwahlula ngo-2 kukuba ekhohlo kwaye ukubrasha ekunene ngumjikelo, kwaye ukuphindaphindwa lixesha leyunithi Inani leenguqu zomjikelo ngaphakathi) liphakathi koluhlu lokuvalelwa kweendlebe zomntu; ngelixa isantya sebrashi yamazinyo eqhelekileyo (3,000 ~ 7,500 amaxesha/min) siguqulelwa kwi-frequency ye-25～62.5Hz, ekwayi-auditory frequency yendlebe yomntu Ngaphakathi komda, kodwa ayinakubizwa ngokuba yibhrashi yamazinyo ye-sonic.
Iibrashi zamazinyo zombane ze-Sonic zinika uhlobo lwesibini lokucoca olunxulumene nesiphumo esibizwa ngokuba yi-fluid dynamics. Ngenxa yesantya esiphezulu kakhulu sesantya sebrashi, iibrashi zamazinyo ze-sonic ziphazamisa ulwelo olusemlonyeni (amanzi, amathe, kunye nentlama yamazinyo), ngokufanelekileyo ziziguqule zibe ziiarhente zokucoca ezifikelela kwimingxuma engenakufikelela kuyo ibrashi, njengaphakathi kwamazinyo nangaphantsi. umgca wentsini.
