日本先锋公司研制出一种新型全自动唱机,采用了一种崭新的抗谐振音臂,极大地提高了拾音效果。现简介如下。音臂的任务是在不引起无用振动的情况下,使拾音头准确对唱片声槽循迹,只拾取声槽记录的有用信号。如果拿汽车来打比喻,可以把拾音头看作车轮,把音臂看作车身,把唱片看作公路。大家知道,当公路有坡时,由于车轮和车身的相对速度差,使车速发 Japan’s Pioneer Corporation has developed a new type of fully automatic phonograph, using a new anti-resonance arm, which greatly improves the pickup effect. Now the introduction is as follows. The task of the boom is to make the pickup accurately track the groove of the record without causing unnecessary vibration and only pick up the useful signal recorded by the groove. If you take a car to play a metaphor, you can put the pickup as a wheel, the sound arm as a body, the record as a road.
