摘要:
现有电影放映机采用硅光电池作还音器件时,还存在一些问题.因此,要提高光学还音的质量,必须认识硅光电池与光电管在光学转换原理上的本质不同,不能把以往采用光电管时所用的配合方法照搬过来.应把硅光电池视作电流源,作电影还音时需把它“短路”运用,并据此设计出不同于传统形式的还音放大器电路.该电路被珠江牌电影放映设备采用后,有关还音质量指标大大高于部颁标准的规定。
Abstract:
In view of the problems existing in current cine-projectors using silicon solar cells as the sound-reproducing device and in order to improve the photo-sound reproduction quality, it is a must to drive home the principal difference of light-electricity exchange between silicon solar cell and photo-tube. The original way of match for phototube should by no means be copied. The paper advises that the silicon solar cell be regarded as a source of electric current, and be short-circuited when used for cinema sound-reproduction. Based on this principle, a new circuit for sound-reproducing amplifier has been designed. After being adopted by the Pearl River brand cine-projector, this circuit’s sound-reproduction quality indices are proved much higher than the standard indices issued by the Ministry of Machinery Industry.
