Mōʻaukala o ka Loudspeakers

A loudspeaker, horn, a me ka horn nenoaiu mea he electromechanical transducer e pio ka uila maika i. Ke kau loudspeaker keʻano i kekahi kanaka ka manaʻo paha Keaukaha, a me ka piha'ōnaehana iloko olaila o ka pa corporating kekahi a oi O Keaukaha a me nāʻano uilaʻoe.

Loudspeakers i ka loa ee iaaanu aey hehee wale i loko o kekahi leo'ōnaehana, a he kuleana no ka hoailono aku audibleʻokoʻa ma waena o ole ia'ālike kani nenoai. Loudspeaker hana ana a me ka pololei ma ka paʻi i ka hoailona me ka pepa ei mea me ka nui loaʻuʻuku iho kona waiwai ma mua o ua o'ē aʻe nā leo? Ieaoa eiaaioa?.

Kekahi mau mea nui i na kanaka, ka poe i mōʻaukala

Ernst W. Siemens i ka mea mua, e wehewehe i ka hōʻeuʻeu a holo'ōwili hao transducer, me ka hoʻopoepoe'ōwili hao o ka uea i loko o kaʻume mākenēki kahua, a kākoʻo ai i ka mea hiki ke neʻe axially. He waihoia i kona US iaoaioa noi no ka Magneto uila i hoʻomākaukauʻia no ka loaa ana i ke ÿano neʻeʻana o ka uila'ōwili hao ma ka pou paialewa pū i hiki ma ka mea, ua haawiia iaoaioa No.149797 ma April 14, 1874.

Oliver Lodge i waiho ia no ka Pelekāne iaoaioa No.9712 ma Apr. 27, 1898, no ka mea, i hoonui ae i loudspeaker me nonmagnetic spacers, e malama i ka lewa nahā i waena o ka pahale loko, a ma waho auamo o ka neʻe'ōwili hao transducer. Kēia i ka ia makahiki āna i noi ai no ka iaoaioa ma luna o kona kaulana Radio tuner.

Thomas Edison Ua puka mai ka iaoaioa Pelekāne iloko o 1881, no ka'ōnaehana hoʻohana'opihia ea me ka amplifyingʻano papa hana no kona hoi koke ana paukūʻolokaʻa phonographs, akā,ʻo ia ultimately noho no ka ninau metala pu kipaku ia e kaʻili lahilahi pili i ka stylus.

Harold Arnold a puni ka makahiki 1925 i hoomaka ai polokalamu ma Bell Labs e hoʻoikaika 'phonographic kani i hoʻopaʻa' ia. Ke makakoho mua i ka lolouila pahu hoʻonui leo ma ka hou holo şarkı, lua i ka mea hoʻolele leo, a me ke kolu ua i ka loudspeaker mea e hoʻoikaika 'ana i ka' O ke kaulike armature huahelu hoʻomohala no ka lehulehu helu wahi.

Bell keʻena hoʻokolohua ma 1931 hoʻomohala i ka mau alanui loudspeakers, kapaʻia puunaueia huahelu no ka h ÷ ike ma HA Frederick o hoʻopapakūʻoki mooolelo. Nā nä alapine kiʻekiʻe Ua UAIAaIN e kekahi mea uuku pepeiaohao me ka alapine (frequency) pane o ka 3000 i ka 13.000 Hz, a me ka haʻahaʻa nä alapine ma ka 12'īniha hōʻeuʻeuʻohana pololei radiator pa alima me ke alapine (frequency) i nā pane i loko o 5db mai ka 50 a hiki i 10,000 Hz.

Pehea ka loudspeakers i hoʻohana e hana

Ka mua loudspeakers hoʻohana electromagnets no ka mea, uaʻaʻole i loaʻa nui, ikaika paʻa nā mākēneki ma kumu kāki.

I ka'ōwili hao o ka electromagnet, i kapaʻia he kahua'ōwili hao, i Hōʻeu e pono ma o ka lua o ka paʻa o ka pili 'o Randy i ka Keaukaha. Ua malama no o Kahualoa Kokohi IeAUPIIe, IAa IO he kūlana pālua, e hana no hoi me ka ka hakui o'ōwili hao kānana i ka mana lako o ka pahu hoʻonui leo i ka i ka loudspeaker i pili.

AC ripple i loko o ka papa i attenuated ma ka hana o ka hele ma ka hakui o'ōwili hao. Eia naʻe, AC laina nä alapineʻohana e pē mālie i ka leo neaiae i hoouna ai i ka leo'ōwili hao, a hou i ka audible hai hum o ka mana i kani nā'ōlelo kūlana kiʻekiʻe.

Ka mea e like ai o ka loudspeaker nenoai a na 1950s i, ma ke kālā no hae, ilihune. Ana Aey? Acaeoey ma ka pa i manao ai a me ka mea i alakai aku ai i ka nui audible hana hou. Ka loa pepeiaohao nui hana hou i loko o kēia 'ōlelo, he mau hana hou ma kaʻohana mea, i ka hoike o ke kiekie ana wela adhesives, iaono? Ienoai paʻa Mākēneki kumuhana, iaono? Ienoai, e kaha i kūpono, kamepiula kōkua mea i manao ai, a finite hehee ai Ka Ikepili.
