1. Umsindo endlebeni nomhlobiso entanyeni:Umzimba ohlakanisiwe omuhle, ukulingana okuzinzile, ofakwe iyunithi yokushayela eguquguqukayo enobubanzi obukhulu ukuletha umuzwa wemvelo nongokoqobo wokulalela.
2. Umsindo oshaqisayo futhi ulalele imisindo emnandi:Ifakwe iyunithi yobubanzi obukhulu obungu-14.2mm, umsindo wefrikhwensi ephansi unothile, uyakhuphuka futhi unamandla, futhi umsindo we-mid-frequency uthambile futhi unezingqimba. Ukukulethela ugqozi olungenamkhawulo.
3. Ukugqoka isikhathi eside ngaphandle kobuhlungu kanye nesipiliyoni sokugqoka esikhululekile:Amathiphu oshaka aklanyelwe ukubamba aqine, futhi avikele izindlebe zakho ezinhlungwini, awuzizwa ukhathele ngemva kokuwagqoka isikhathi eside.
4. Uzibuthe ozenzakalelayo nokugcinwa ngaphandle kokusonta:Idizayini kazibuthe yokugcina kalula, uma ingasetshenziswa, ama-earphone angalengiswa ngokunethezeka nangokuphephile entanyeni, alungele isitoreji sakho nokusetshenziswa, futhi avimbele ukulahlekelwa.
5. Akulula ukuzithintitha kanye nenkululeko ngaphandle komthwalo:Usayizi wesisindo esilula, ulula futhi awuphoqelekile, okuvumela ukuthi wenze ukuzivocavoca kalula nangokukhululeka.
6. Ubuciko obuphelele:Idizayini ye-matte aluminium alloy cavity, ukuthungwa okuhle kakhulu. Igcwele umuzwa nomuzwa wesayensi nobuchwepheshe, ukuthungwa kwensimbi kanye nezinga lokubukeka ukuqinisa ihedisethi, ukukubonisa ukubukeka okujulile nokuyingqayizivele.
7. Iyunithi yokushayela engu-10mm: Ifakwe iyunithi yokushayela engu-10mm enkulu,umfutho omangalisayo uyazibonakalisa, umsindo wemvamisa ephansi unothile futhi unamandla, futhi imvamisa emaphakathi ithambile futhi inezingqimba.Letha amandla angenamkhawulo kuwe.
8. I-clamp yeselula:Noma kunini, lungisa ubude bocingo, unciphise ukungqubuzana nokushwiba lapho ulalela umculo kwezemidlalo, wehlise ngempumelelo umphumela we-stethoscope.
9. Izinto zocingo ezinhle:I-copper core ehlanzekile kakhulu, hhayi kuphela i-anti-pull anti-winding, ikhwalithi yomsindo ecebile nethambile.
