Kukula Kwamagalimoto Oyimbira Magalimoto & Makampani Apolisi A Siren Ku China
Chitukuko chamakampani olankhula mokweza pamagalimoto & makampani a siren apolisi ku China
1 njira zachitukuko
Popeza palibe kusintha kwakukulu pamapangidwe amtundu wa olankhula magalimoto, opanga ambiri olankhula magalimoto amadzipereka kuzinthu zokongoletsa zopangira, ndipo amakhala ndi ndalama zochepa kuti apititse patsogolo kumveka bwino.Zatsopano za masitayelo osiyanasiyana zimakhala ndi mawonekedwe a chivundikiro cha ukonde chonyezimira komanso beseni lonyezimira, ndipo ma tweeter ochepa otsogola amagwiritsidwa ntchito ngati mawu abwinoko.Pamene mpikisano ukukulirakulira kuchokera m'malo atatu akuluakulu operekera ma speaker olankhula magalimoto ku Hong Kong, Taiwan ndi ku China, opanga ambiri akuwonjezera luso lawo lofufuza ndi chitukuko ndikusunga mitengo yotsika kuti atsimikizire kupambana pampikisano.
Ambiri opanga zokamba zamagalimoto amaneneratu kuti mitengo ya katunduyo idzakhalabe yokhazikika mu theka loyamba la 2004. Koma makampani a ku China ku China amanena kuti ngati mtengo wa mapulasitiki ndi zitsulo ukukwera, ndipo ngati kuchotsera msonkho kumachepetsedwa, mtengo wa katundu ukhoza kukwera pambuyo pake.Ngakhale pali mavutowa, opanga ambiri akadali ndi chiyembekezo chokhudza momwe 2004 ikuyendera, ndipo ndalama zakunja zikuyembekezeka kukula ndi 20%.
(1) Hong Kong: mawonekedwe apamwamba komanso mawu abwino
Opanga zoyankhulira zamagalimoto ku Hong Kong akugwira ntchito molimbika kukonza mawonekedwe ndi kapangidwe kawo kuti apititse patsogolo kumveka kwazinthu zawo.Chifukwa kukula ndi mawonekedwe a zokuzira mawu ndizokhazikika, kapangidwe ka chivundikiro cha mauna ndi zokutira za beseni logwedezeka ndi madera omwe angagwiritsidwe ntchito mosinthika ndi wopanga.Akuti Shi JA Zhong acoustic fty Ltd ili kale ndi theka la mauna, theka la oyankhula agalimoto a shokegille.Maonekedwe amtunduwu wa chivundikiro cha theka la ma wheel mesh ndi ofanana ndi m'mphepete mwa gudumu lagalimoto, ndipo amapangidwa ndikupangidwa kuti akwaniritse zofunikira za aerodynamic za ogwiritsa ntchito.Chophimba cha mauna chimapangidwa ndi ABS.Kampaniyo ikuperekanso IMPP (jekeseni wopangidwa ndi polypropylene) kuti ilowe m'malo mwa zida zomwe zimagwedezeka (monga mapepala, pulasitiki, PP ndi fiber).
Zopangidwa ndi beseni logwedezeka.IMPP sifunikira kukutidwa kapena kupangidwa ndi electroplated chifukwa ma pigment amawonjezedwa pazinthuzo asanapangidwe jekeseni.Kampaniyo idapeza zida za IMPP kuchokera ku Taiwan.Mbali ina ya kafukufuku ndi chitukuko ndi zokutira pamwamba pa miphika yogwedezeka.Electroplating ndiye chisankho chofala kwambiri.Koma Shija Zhong amagwiritsa ntchito njira yopukutira pamwamba kuti pamwamba pawoneke ngati chimbale cha CD, chokhala ndi pologalamu yotchuka komanso yonyezimira.Opanga ambiri apanganso zosintha zazing'ono pamapangidwe a okamba.Zina mwazinthu zatsopano za tweeter zili ndi filimu yophimbidwa ndi ferrofluid ndi aluminiyamu, komanso maginito akuluakulu kuti azitha kutulutsa mawu.Mapiko Cheong Eletroa-Malinga ndi coustie industrial Ltd., magnetofluid amachepetsa kuthekera kwa okamba kutenthedwa, amene kuposa 10% okwera mtengo kuposa amene alibe.Kampaniyo yayambitsa kugwiritsa ntchito zokutira zotayidwa pa PP vibration beseni la speaker mkulu.
Shi JA Zhong amagwiritsa ntchito maginito okulirapo kuti athandizire kumveketsa bwino kwa olankhula.Zolaula zokhala ndi maginito izi zimakhalabe zopikisana pamtengo.Kampaniyo ikhoza kuperekabe mtengo womwewo wa ma 993g (350Z) olankhula maginito ngati 653 g (23 oz).
Pali pafupifupi 30 opanga zolankhula zamagalimoto ku Hong Kong.Kugulitsa kwa anthu osankhika a en gineering (wanzeru) Co.Wing gheong adawonetsa kuti kufunikira kwa zinthu kukukula mwachangu kuyambira pakati pa 2003, ndipo kutumiza kunja mu 2004 kudzakwera ndi 8%.
Opanga ambiri akutenga nawo gawo pamipikisano yoyika, koma mpaka pano mtengo wazogulitsa wakhala wokhazikika mkati mwa $ 5-810 (FOB).Kupatulapo ndi mapiko gheong, omwe mtengo wake ndi 5% wotsika kuposa zinthu zina.
(2) Taiwan: kapangidwe kazinthu kamayang'ana mawonekedwe
Mu 2004, olankhula magalimoto aku Taiwan adzakhala ndi mawonekedwe owala.Mitundu yosiyanasiyana yazinthu imakhala ndi mawonekedwe a aluminiyamu otayira ndi zitsulo zachitsulo, komanso mabeseni ogwedezeka a kaboni kapena magalasi.Maonekedwe a mankhwala atsopano ndi osalala.Kumveka bwino kwa okamba nkhani kumakhala bwino chifukwa chogwiritsa ntchito mawu osamva kutentha.
Pali pafupifupi opanga 10 olankhula magalimoto ku Taiwan.Ambiri a iwo asamutsira zida zawo zopangira kunja.Ambiri a iwo ali kum'mwera kwa dziko lapansi kumene ndalama zogwirira ntchito ndi malo zimakhala zochepa.
Opanga ambiri amayembekezera kuwonjezeka kwa 10% - 20% kwa kufunikira kwa zinthu mu 2004, ndipo zatsopano zambiri zipitilira kugulitsidwa.United States ndi Japan akadali misika yayikulu yotumiza kunja.Opanga ambiri akukhazikitsa zokuzira mawu zotsika mtengo ku Middle East ndi Southeast Asia.
Mu 2004, yuhcherng ipanga zokuzira mawu zatsopano mumayendedwe a OEM kuti zilowe m'malo mwazopanga zokha.Kampaniyo imatha kupanga zokuzira mawu 40000 pamwezi, pomwe kugunda kwakukulu kumakhala ndi mizere 4 yopanga ku Shenzhen, yomwe imatha kupanga okamba magalimoto 60000 pamwezi.Tronstar adzatero
50% ya zinthu zake zimatumizidwa kwa ogula OEM, omwe chomera cha Guangdong chimatha kupanga olankhula magalimoto 200000 pamwezi, ndipo kampaniyo ikukonzekera kuwonjezera mphamvu zake zopanga mwezi ndi 50% mu 2004.
Otsatsawa ali ndi zaka zopitilira 20 pakupanga ma speaker azigalimoto, ndipo apeza IS09001, IS09002 certification ndi QS9000 certification.
Kuphatikiza apo, chimango cha mphika wachitsulo cha eletroniar chimagwiritsidwa ntchito m'malo mwa eletroniar.Highhitco imagwiritsa ntchito makina a CNC kuti apange okamba magalimoto owoneka bwino.
Tronstar adati oyankhula a cf-ack omwe adapangidwa ndi kampaniyo amagwiritsa ntchito maginito ang'onoang'ono komanso owonda a NdFeB kuti atsimikizire mphamvu ya maginito.Mndandanda wazinthuzi umagwiritsanso ntchito coil ya mawu ya ASV yosagwira kutentha.Mtengo wamtengo ndi $20-825 / zopangira zopangidwa ndi aluminiyamu ndi $10-815 pa bonsai yachitsulo.Zikuyembekezeka kuti mitengo yazinthu izikhalabe yokhazikika posachedwa.
Nkhondo yochulukirachulukira komanso mitengo yamtengo wapatali yakakamiza opanga masipika agalimoto aku Taiwan kuti achepetse kupanga ndikusinthira zinthu zawo kukhala zinthu zina, monga hi fi system, makina olankhulira kunyumba ndi zoyankhulira pakhoma.Mwachitsanzo, yuh Cherng Electronics Corp. idachepetsa kupanga zoyankhulirana zamagalimoto kuchokera pafupifupi 20% mpaka 5%.
(3) Mainland China: zoyambira zitatu zopangira
Pali zitatu zazikulu zopangira zokamba zamagalimoto ku China: Guangdong imapanga zinthu zapakati komanso zapamwamba;Jiangsu ndi Zhejiang amapanga mankhwala otsika;Hebei ndi malo atsopano othandizira, omwe amapanga oyankhula osiyanasiyana amagalimoto a coaxial, kuphatikiza 2-way, 4-way, 6-way ndi 8-way mankhwala, okhala ndi IMPP ndi PP kugwedera beseni, ndi tilinazo 86-93 dB ndi pafupipafupi mayankho osiyanasiyana. 80Hz-20kHz.Innovation imayang'ana pa mawonekedwe ndi mawonekedwe okongola a beseni la beseni ndi beseni logwedezeka.Phukusi la speaker
Mitengo ya mapulasitiki ndi zitsulo, kuphatikizapo mapulasitiki ndi zitsulo, idzakwera mu 2004;opanga ambiri akukumananso ndi mavuto aakulu.Boma lachepetsa misonkho posachedwa kwa olankhula magalimoto kuchokera pa 13% mpaka 4%, zomwe zidzakulitsa mtengo wazinthu.Ogulitsa ku China akuyambitsa masipika agalimoto opangidwa kumene chaka chilichonse, ambiri mwa iwo ndi zopangidwa zopangidwa ndi ODM.Ningbo akupitiliza kuwongolera elctronie Co. Ltd imayika 6.5% yazogulitsa zake pachaka ku R&D ndikupanga zinthu zatsopano 20-30 chaka chilichonse.Peiying imayika 5% yazogulitsa zake pachaka mu R&D, ndipo ili ndi gulu lofufuza ndi chitukuko la anthu 60, ndipo imapanga zinthu zatsopano pafupifupi 60 chaka chilichonse.Jiashanboss Electronics Co. LD imagwiritsa ntchito gulu lamphamvu la R & D la anthu 50 kukhazikitsa zinthu zatsopano 30-50 chaka chilichonse.Opanga zapakhomo ali ndi chiyembekezo chamtsogolo cha 2004 ndipo akuwongoleranso mphamvu zawo zopangira.Peiying imatha kupanga zinthu 150000 pamwezi ndipo imatha kupereka mitundu yopitilira 100 ya zokuzira mawu.Ali ndi chidaliro kuti zogulitsa kunja zipitilira kukula ndi 20% mu 2004, kotero akhazikitsa zatsopano.
Mzere wowonjezera mphamvu yopangira.Kuthekera kwa mwezi kwa Ningbo kusunga kwafika mayunitsi 400000, ndipo kutumiza kunja kwa Ningbo Keep kukuyembekezeka kukwera ndi 50% mu 2004.
Opanga ambiri ayamba kulabadira ziwonetsero zamalonda zakunja ndikuwonjezera malonda awo ogulitsa kunja.80% ya Hanghou hi - zopangidwa zomveka za Elee tronie FTY zimaperekedwa kwa makasitomala a OEM, ndipo maoda ambiri akunja alandilidwa.Zogulitsa zonse zimatumizidwa ku United States, Europe, Middle East ndi Africa.
