在一台电唱机上,最不起眼的元件要数唱针了。这也难怪,唱针的体积与整个唱机比较起来,大小相差太悬殊了。一般的宝石唱针直径是0.5毫米,长度不足2毫米;而金刚石唱针的直径只有0.3～0.4毫米,长度0.7毫米左右,也就是说还不及文章中的一个“,”符号大。所以一般人都不太注意唱针。为了减少电唱机的失真,提高音质,人们往往特别注意放大器、音臂、唱头和电机等部件的研究与改进,殊不知在一整套高保真电唱机装置中,小小唱针的作用犹如军队中的先锋一样,是一个极为关键的元件呢。一、唱针的形状唱针的形状用肉眼很难看得清楚。拿一枚宝石唱针放在显微镜下便可以看出唱针是由二部分组成的(图1):上半部分是园柱
On a record player, the most obscure components need to be styled. It is no wonder that the volume of the stylus compared with the entire record player, the size difference is too poor. General gem needle diameter is 0.5 mm, length less than 2 mm; and diamond needle diameter of only 0.3 to 0.4 mm, length 0.7 mm or so, that is not as good as the article in a “,” symbol. So most people do not pay attention to sing needle. In order to reduce the distortion of the record player and improve the sound quality, people often pay special attention to the research and improvement of the amplifier, the arm, the singing head and the motor and other components. However, in a set of hi-fi record player devices, the small needle acts like a vanguard in the army , Is a very critical component yet. First, the shape of the needle The needle shape is difficult to see clearly with the naked eye. Take a gemstone stylus on the microscope you can see that the stylus is composed of two parts (Figure 1): the upper part of the column
