Work as the professional speaker maufacnturer, XDEC speaker, also know these two types of speaker lead wire good and bad,
lead wire is widely saw in multimedia speaker,
For now, the speaker products are widely to been seem silver lead wire and copper lead wire
lead wrie fucntion is to connect voice coil and the terminal boad, and act a angle for speaker cone work proprely. has connection and
Two type lead wries parameter and specification silver VS copper:
copper lead wire
Melting point：1083℃
Product elasticity：Slight harder,easy to form an arc shape
Solderability:Easy to tin and less prone to virtual soldering
esistance time：6 months
Product characteristics：
1.Mainly use oxygen-free copper material, featuring low impedance and minimal loss characteristics,feature is low impedance and low coss. Oxygen-free copper has high purity, small impedance,suitable transfer high quality audio signal, high transfer stablity
2.Copper lead wire has good thermal conductivity and corrosion resistance, and can maintain stability in humid environments and chemical corrosion conditions.
silver lead wire
Melting point：967.81℃
Product elasticity：Slight softer,Arc instability
Solderability：Easy to infiltrate tin,material easy get hard Oxidation
Oxidation
resistance time：3 months
Product characteristics：
1. Silver lead wire slight soft,good flexibility, easy to solder during welding, silver wire has good conductivity, but higher price
2.Solder with silver stranded wire , welding point is also prone to tin immersion, can cause the wire at the welding point to harden. If the speaker works for a long time, the hardened part is easily damaged and broken
