    • A rotor, vibration motor having the same, and fabrication method thereof are disclosed. A rotor according to an embodiment of the invention comprises a first layer on which are formed a plurality of commutators, a second to an n-th layer—wherein n is 4 or greater—on which are formed a plurality of patterned coils that are connected with the commutators, insulation layers interposed in-between the first to the n-th layers; blind via holes which connect the commutators of the first layer with the patterned coils formed on the second layer and which connect the patterned coils formed on the (n−1)-th layer with the patterned coils formed on the n-th layer, and a plurality of through holes which connect the patterned coils formed on the second to the (n−1)-th layers, where the patterned coils located on the second to the (n−1)-th layers are connected by means of different through holes.
    • 公开了一种具有该转子的振动电机及其制造方法。 根据本发明实施例的转子包括第一层,其上形成有多个换向器,第二至第n层,其中n为4或更大,在其上形成有多个图案化的线圈,其连接 换向器,介于第一至第n层之间的绝缘层; 将第一层的换向器与形成在第二层上的图案化线圈连接并将形成在第(n-1)层上的图案化线圈与形成在第n层上的图案化线圈连接的盲孔,以及 连接形成在第(n-1)层上的图案化线圈的多个通孔,其中位于第二至第(n-1)层上的图案化线圈通过不同的直通 孔。
