The invention discloses a magnetoelectric coupling lock cylinder which comprises a bracket. The bracket is characterized in that a plurality of groups of password recognition holes in array distribution are formed in the middle of the bracket, the password recognition holes comprise a magnetic source hole, a first transition hole, a second transition hole and a magnetoelectric coupling hole whichare successively and coaxially distributed from top to bottom, and a key slot is formed between the first transition hole and the second transition hole; a permanent magnet is arranged in the magneticsource hole, a giant magnetostrictive rod is arranged at the inner end of the magnetoelectric coupling hole, and a piezoelectric ceramic pile is arranged at the outer end of the magnetoelectric coupling hole; the magnetoelectric coupling lock cylinder also comprises a key, wherein magnetic conductive sheets corresponding to the password recognition holes one by one are arranged on the key, the thickness of the magnetic conductive sheet is an adjustable volume directly associated to a password, and when the key is inserted into the end from the key slot, the magnetic conductive sheets are arranged coaxial to the corresponding password recognition holes. The magnetoelectric coupling lock cylinder has the characteristics of being high in reliability and hard to break.
本发明公开了一种磁电耦合锁芯，包括支架，其特征在于：所述支架中部设置有多组阵列分布的密码识别孔，所述密码识别孔包括由上至下依次且同轴分布的磁源孔、第一过渡孔、第二过渡孔和磁电耦合孔，所述第一过渡孔和第二过渡孔之间设置有钥匙槽；所述磁源孔内设置有永磁铁，所述磁电耦合孔的内端设置有超磁致伸缩棒，外端设置有压电陶瓷堆叠，所述磁电耦合锁芯还包括钥匙，所述钥匙上设置有与所述密码识别孔一一对应的导磁片，所述导磁片的厚度为与密码直接相关的可调节量，当钥匙从钥匙槽中插入到底时，每个导磁片均与其对应的密码识别孔同轴分布。该磁电耦合锁芯具有可靠性高、难破解的特点。
