这里我再来摘一段这书里的文字。
A moving coil cartridge works on exactly the same physical principles, but the magnets are stationary and the coils move. A moving coil cartridge generally has much less moving mass than a moving magnet cartridge. Consequently, a moving coil cartridge can generally track better than a moving magnet type, and also have better transient response. With less mass to put into motion ( and less mass to continue moving after the motivation force has stopped ), moving coil cartridges can better follow transient signals in the record.
动圈唱头的工作原理和动磁唱头的原理是一样的,只是动圈唱头中的磁铁是固定的,而线圈是运动的。通常动圈式唱头的质量要轻于动磁式唱头。这样就导致了动圈式唱头的循轨能力要好于动磁式唱头。同时,也导致了动圈式唱头有更好的瞬间反应。动圈式唱头可更好地循轨,因为它只需移动较轻的质量,在信号停止后,它也只需推动轻的质量而保持它重新运动。
动圈式唱头质量轻这不是观点,而是一个基本的事实。
这里我再看看动圈式唱头的构造。
图中的英文字SingaI Coils所指之处,一般来说,大致为十至三十圈。这样它的质量是很小的。当然,我讲的质量(moving mass)应包整个运动部分的质量。
