一只八音玩具冲锋枪,枪内微型喇叭损坏后,因手头无该型喇叭替换,试用Φ27mm陶瓷片换上,结果发音嘶哑,无法使用。试在输出线与陶瓷片之间串接一只输出变压器,声音效果立即大为改善,但因变压器体积过大装不进枪壳而无法实施。最后通过试验,在陶瓷片两端并上一只单声道旧磁头后,再接上原喇叭线,经试用,发音清脆圆润,完全能满足使用要求(只是发音较原来略小)。将旧磁头用胶纸粘贴在手枪壳内空处即可。
An eight-tone toy submachine gun, miniature gun damage to the gun, due to the absence of the type of horn on hand to replace the trial Φ27mm ceramic replaced, the result is hoarse, can not be used. Trying to connect an output transformer in series between the output line and the ceramic, the sound effect immediately improved greatly, but due to the volume of the transformer is too large not fit into the gun shell and can not be implemented. Finally, through the experiment, the ceramic piece at both ends and a single monaural old head, then connected to the original speaker line, the trial, pronounced crisp mellow, fully able to meet the requirements (only slightly smaller than the original pronunciation). The old head with adhesive tape paste in the pistol shell can be empty.
