單揚(yáng)聲器故障的原因分析

單揚(yáng)聲器故障的原因分析

單揚(yáng)聲器故障的原因分析如下

彈性波：在長(zhǎng)期的機(jī)械運(yùn)動(dòng)下，由于不同材料的穩(wěn)定性不同，容易發(fā)生彈性疲勞。

凱悅音響

1，彈性波變形，使音圈移動(dòng)，音圈偏心，產(chǎn)生摩擦;

2.彈跳波與軟鐵線圈碰撞并撞擊T型鐵的底部，產(chǎn)生撞擊鋼的聲音;

3.彈性波和音圈的中央橡膠變質(zhì)(音圈太熱或膠水不夠堅(jiān)硬)，導(dǎo)致中央部分分離。

膜片：揚(yáng)聲器膜片由紙，金屬，PP等各種材料制成。長(zhǎng)期使用時(shí)，紙盆的溫度會(huì)受到水分和水分的影響，這會(huì)導(dǎo)致紙盆的重量發(fā)生變化并惡化。會(huì)改變?cè)瓉淼囊糍|(zhì)。

1.音圈的中央部分已脫膠。在長(zhǎng)期過度使用下，過載的輸出功率將導(dǎo)致音圈過熱，從而使中心凝膠發(fā)生變化，從而引起脫膠和噪音。

2.If the power output is too large and the diaphragm vibrates violently for a long time, if the heat resistance of the glue is sufficient at this time and the rigidity of the paper cone is not enough, it will cause the paper cone deformation meter to rupture, that is, an abnormal sound will be generated. ;

3. Man-made damage and insect bites can also cause damage and abnormal sounds.

Overhang

1. Sponge foam edge or rubber or cloth edge, etc. After a long period of vibration and the impact of the climate, the sponge will deteriorate and corrode;

2. Insect bites and man-made destruction.

Dust cover

1.The dust cover is loosened, causing noise when it collides with the paper cone;

2. The dent of the dust cover can cause abnormal sounds.

Voice coil

由于膠水過熱或其他原因，音圈的中心點(diǎn)會(huì)與T型鐵摩擦，這將導(dǎo)致音圈斷開或短路。

音圈導(dǎo)線斷裂，這是因?yàn)榧堝F中心點(diǎn)的延伸硬度不均勻，會(huì)導(dǎo)致紙錐斷裂而漆包線斷裂;

鉛的彎曲部分在長(zhǎng)期使用時(shí)可能導(dǎo)致氧化斷裂。
