manufa na aiki

Tare da na'urar magana ana jerawa, da muka je da manufa na aiki. The aiki manufa na kuzarin kawo cikas ne kamar haka: na yanzu sunã gudãna a cikin nada sa shi ya zama perpendicular zuwa hawa da sauka a cikin Magnetic filin. Wannan tsarin entrains da diffuser, suna ɓuɓɓugar da shi canza tare da wani mita na kawota halin yanzu, da kuma haifar da igiyar ruwa ta sallami. A diffuser fara makarkata da kuma haifar da sauti tãguwar ruwa, wanda za a iya gane da mutum kunne. Su ne a cikin nau'i na wani lantarki siginar daukar kwayar cutar da amfilifa. Saboda haka, sauti bayyana.

Frequency dogara a kan kauri daga cikin Magnetic tsakiya da kuma magana size. A ya fi girma girma qara Magnetic rata a cikin Magnetic tsarin, da kuma tare da shi, da kuma qara tasiri nada rabo. Wannan shi ne dalilin da ya sa m jawabai ba zai iya rike da low mitoci a cikin kewayon 16-250 Hz. Su m dokin mita 300 Hertz fara da ƙare a 12,000 hertz. Wannan shi ne dalilin da ya sa muhimmancin wheezing, a lokacin da ka ga wriggle daga cikin sauti zuwa iyakar.

Maras muhimmanci lantarki juriya

Waya samar da yanzu da nada yana da juriya da kuma reactance. Don sanin matakin na karshen shi injiniyoyi auna a mita na 1000 Hz da kuma sakamakonsa darajar da aka kara wa juriya da murya nada. Mai magana da juriya matakin ne 2, 4, 6 ko 8 ohms. Wannan wani zaɓi kamata a yi la'akari lokacin da sayen wani amfilifa. Yana da muhimmanci a yarda a kan matakin da load.

mita band

An riga an ce cewa mafi yawan electrodynamics taka kawai wani ɓangare na mita cewa mutane za su iya sani ba. Make wani m magana da cewa za su iya taka da cikakken kewayon 16 hertz zuwa 20 kilohertz ne ba zai yiwu ba, don haka da mita da aka raba uku kungiyoyin: low, matsakaici da kuma high. Bayan haka, designers fara ƙirƙirar masu kuzarin kawo cikas dabam ga kowane mita. Wannan yana nufin cewa woofers ne mafi kyau mu jimre wa da bass. Sun yi aiki a kan wani fanni na 25 Hz - 5 kHz. High-an tsara aiki tare da sauti da highs (Saboda haka da na kowa suna - "beeper"). Sun yi aiki a kilohertz mita iyaka 2 - 20 kHz. Midrange naúrar a cikin kewayon 200 Hz - 7 kHz. Injiniyoyi har yanzu yunƙurin halitta high quality-broadband magana. Alas, da farashin kuzarin kawo cikas shi ne saba wa ta inganci da bai gaskata da shi.

A kadan game mobile magana

domin waya ta jawabai ne daban-daban daga "adult" model na gaskiya. Gano wani hadadden tsari a cikin mobile jiki ne ba na gaskiya ba, don haka injiniyoyin tafi zuwa ga abin zamba da kuma maye gurbin wani adadin abubuwa. Alal misali, coils zama immobile, kuma a maimakon amfani da membrane diffuser. domin waya ta jawabai ƙwarai Sauki, saboda haka, ya sa ran su don sauti ba daraja da inganci.

A mita iyaka da za su iya rufe wani kashi muhimmanci quntata. A cewar ta sauti, ya ne mafi cancanta ga m-mita na'urorin, kamar yadda a jikin wayar babu wani ƙarin sarari ga shigarwa na lokacin farin ciki Magnetic tsakiya.

The na'urar kuzarin kawo cikas a cikin wayar hannu ba kawai size amma kuma da rashin 'yancin kai. damar da na'urar an iyakance ga software. Wannan ne yake aikata kare zane na jawabai. Mutane da yawa cire wannan iyaka da hannu, sa'an nan tambaya: "Me ya sa aka wheezing jawabai?"
