style="text-indent:25px">鋼琴的擊弦機(jī)：鋼琴是西洋古典樂(lè)器中的一種鍵盤(pán)樂(lè)器，并有著8000多個(gè)零部件。其中鋼琴的擊弦機(jī)就是鋼琴的主要零部件之一。鋼琴的擊弦機(jī)是由鐵架、主梁、枕梁、調(diào)節(jié)器和驅(qū)動(dòng)器、轉(zhuǎn)擊器，上海流行鋼琴網(wǎng)、止音器等多個(gè)零件構(gòu)造而成。琴鍵擊發(fā)琴弦震動(dòng)就是靠這個(gè)部位的，也就是說(shuō)想要鋼琴發(fā)聲就必須靠這個(gè)“擊弦機(jī)”，上海流行鋼琴網(wǎng)。鋼琴發(fā)聲的原理是由彈奏著觸動(dòng)琴鍵，琴鍵進(jìn)而頂起擊弦機(jī)，使得琴槌敲擊琴弦列，發(fā)出聲音，我們聽(tīng)到的鋼琴聲就是這樣來(lái)的。另外目前市面上使用的鋼琴擊弦機(jī)的用料里有實(shí)木，塑料等材質(zhì)生產(chǎn)的擊弦機(jī)。一般歐美國(guó)家生產(chǎn)的鋼琴所使用的擊弦機(jī)都會(huì)使用以實(shí)木為主的材料生產(chǎn)鋼琴。但是部分日本及國(guó)內(nèi)一些廠(chǎng)家會(huì)使用塑料等材質(zhì)生產(chǎn)的擊弦機(jī)。其中塑料作為一種高分子化合物，在穩(wěn)定性上會(huì)有一些優(yōu)勢(shì)。但是作為鋼琴來(lái)說(shuō)，純實(shí)木的擊弦機(jī)優(yōu)勢(shì)遠(yuǎn)大于塑料的。況且在用實(shí)木生產(chǎn)過(guò)程中，正規(guī)廠(chǎng)家都會(huì)非常注重自然風(fēng)干的時(shí)間及恒溫恒濕管控等工藝。經(jīng)過(guò)技術(shù)處理以后的純實(shí)木的擊弦機(jī)在穩(wěn)定性上就不輸塑料用材的擊弦機(jī)了。目前舒意鋼琴（上海）有限公司所生產(chǎn)的意大利舒爾茨波爾曼鋼琴，英國(guó)查倫鋼琴，上海流行鋼琴網(wǎng)，英國(guó)威頓鋼琴等都是采用實(shí)木材料生產(chǎn)的擊弦機(jī)。鋼琴能鍛煉孩子的智力，均衡地開(kāi)發(fā)孩子左右腦的潛能。上海流行鋼琴網(wǎng)</p><div

style="text-indent:25px">如果鋼琴弦軸釘和琴弦生了銹斑，有的人會(huì)往弦軸何和琴弦上涂抹凡士林或機(jī)油，如果油類(lèi)從弦軸釘滲進(jìn)弦軸孔內(nèi)，就會(huì)給鋼琴調(diào)音帶來(lái)麻煩，嚴(yán)重的根本無(wú)法調(diào)音。琴弦上的油漬粘到了制音器音頭上、小槌頭上，不但會(huì)影響毛氈的顏色，而且制音效果和音色也將變壞。弦軸和弦上的油漬時(shí)間一長(zhǎng)會(huì)粘上灰塵，這樣既不美觀，防銹的能力反而更差。如果遇到這種情況。弦軸部位的銹斑清理可用干布蘸上少許汽油和機(jī)油擦拭一遍，再用干布擦盡油漬。琴弦部分的輕微銹斑可用酒精調(diào)鉛粉，用氈布蘸上用勁擦拭，直到銹跡消失。上海鋼琴入門(mén)英國(guó)查倫鋼琴建議在學(xué)琴的過(guò)程當(dāng)中搭配一臺(tái)音色**，手感好的進(jìn)口鋼琴陪伴孩子的左右也是很重要。</p><div

style="text-indent:25px">關(guān)于鋼琴的款式和品質(zhì)，許多廠(chǎng)家便在鋼琴的外觀款式上做文章，制作出的鋼琴外觀樣式花樣繁多、迎合了許多人追新求異的心態(tài)。特別是一些技術(shù)力量薄弱的中小型鋼琴企業(yè)更是如此，以此爭(zhēng)得更多的顧客和更高的利潤(rùn)。鋼琴重要的是它的使用性能，應(yīng)該在鋼琴聲學(xué)品質(zhì)和機(jī)械性能好的前提下再考慮選擇喜歡的外觀樣式。如英國(guó)查倫鋼琴，意大利舒爾茨波爾曼鋼琴等其外觀簡(jiǎn)捷、穩(wěn)重大方，而其內(nèi)在品質(zhì)是其他很多鋼琴無(wú)法相比的。因此選購(gòu)鋼琴時(shí)徒有其表的鋼琴要格外注意。</p><p style="text-indent:25px">鋼琴的穩(wěn)定性與耐久性，每臺(tái)鋼琴都要作定期的調(diào)整，而造成鋼琴走音的原因之一就是弦所受的巨大張力。因此鋼琴的背架結(jié)構(gòu)要經(jīng)過(guò)精心的設(shè)計(jì)，去提高抗應(yīng)變的效率和延長(zhǎng)調(diào)整的間隔期。定期保養(yǎng)、整音、調(diào)律的方法也是能夠有效提高鋼琴音色穩(wěn)定和準(zhǔn)確性。鋼琴屬于十分經(jīng)久耐用的樂(lè)器，誰(shuí)都希望鋼琴的性能、聲音與外觀能長(zhǎng)期地保持不變，鋼琴的耐久性好，是要通過(guò)精心地選擇材料，使用先進(jìn)的生產(chǎn)設(shè)備以及在整個(gè)制造過(guò)程中進(jìn)行極嚴(yán)格的品質(zhì)管理才能實(shí)現(xiàn)的。超越兩百年的經(jīng)典，英國(guó)查倫鋼琴，和您一起超越經(jīng)典。</p><div

style="text-indent:25px">鋼琴實(shí)木鍵盤(pán)和復(fù)合鍵盤(pán)：鋼琴的鍵盤(pán)工藝目前來(lái)說(shuō)有兩種制作方式。一種是實(shí)木鍵盤(pán)，一種是復(fù)合鍵盤(pán)。實(shí)木鍵盤(pán)顧名思義就是用實(shí)木做成的鍵盤(pán)。與復(fù)合鍵盤(pán)相比較具有環(huán)保、健康、耐用、手感佳、外形美觀等優(yōu)點(diǎn)。早期實(shí)木鍵盤(pán)因很多廠(chǎng)家制作工藝落后，所以會(huì)在國(guó)內(nèi)一些溫濕度要求比較高的地區(qū)，如東北地區(qū)等會(huì)產(chǎn)生實(shí)木鍵盤(pán)變形及穩(wěn)定性欠佳等問(wèn)題。所以當(dāng)初也有很多廠(chǎng)家會(huì)選擇使用成本更低，穩(wěn)定性更好的復(fù)合鍵盤(pán)。但是國(guó)內(nèi)經(jīng)過(guò)**近十幾年的快速發(fā)展，目前實(shí)木鍵盤(pán)的穩(wěn)定性也已經(jīng)非常高了。目前國(guó)內(nèi)正規(guī)品牌提供的鋼琴基本上也都是在使用實(shí)木鍵盤(pán)制作的鋼琴。畢竟如上所述實(shí)木鍵盤(pán)的好處還是非常明顯的。包括查倫鋼琴全系產(chǎn)品及其他真正的歐洲**進(jìn)口品牌鋼琴也是一直堅(jiān)持使用實(shí)木鍵盤(pán)，當(dāng)然這背后也印證了歐洲制造工藝及技術(shù)標(biāo)準(zhǔn)的先進(jìn)性。不論是和西洋樂(lè)器結(jié)合還是與東方樂(lè)器合奏，鋼琴都能很好的進(jìn)行配合。上海王焱鋼琴論壇</p><p style="text-indent:25px">英國(guó)查倫鋼琴的音板是根據(jù)人耳所能識(shí)別的音頻物理特性設(shè)計(jì)，采用的是上下不等厚結(jié)構(gòu)制作而成。上海流行鋼琴網(wǎng)</p><p> 鋼琴音板：音板位于鋼琴鐵板和背架之間，被固定在鋼琴碼克之中，當(dāng)琴槌敲打琴弦產(chǎn)生震動(dòng)，音板通過(guò)捕捉碼橋傳來(lái)的琴弦震動(dòng)而產(chǎn)生音調(diào)，進(jìn)而發(fā)出鋼琴美妙的聲音傳導(dǎo)到您的耳中。查倫鋼琴的音板是根據(jù)人耳所能識(shí)別的音頻物理特性所設(shè)計(jì)。其中音板材質(zhì)和工藝的好壞會(huì)直接影響一臺(tái)琴的整體效果。音板是控制在一定幾何尺寸范圍內(nèi)的木質(zhì)徑切板狀結(jié)構(gòu)，音板會(huì)將把榔頭打擊琴弦所產(chǎn)生的震動(dòng)重新傳導(dǎo)到空氣中。鋼琴音板主要是由音板、肋木、音板框和弦碼組成。鋼琴音板設(shè)計(jì)及壓制方式?jīng)Q定鋼琴的共振效果、泛音的層次和豐富程度以及聲音傳播速度等構(gòu)成鋼琴好壞的關(guān)鍵性指標(biāo)。這些統(tǒng)統(tǒng)歸為一個(gè)詞匯，就是鋼琴的“音色”。
