    摘要： An electromagnetic sound generator has a case provided with a yoke, a magnet, a vibrating plate and a coil, and a pair of leads. An end of the coil and the other end of the leads is secured to the case so as to be connected to an outside terminal. A terminal connecting device is provided for connecting the end of the lead to the outside terminal. The terminal connecting device comprises a cylindrical case secured to the case, a connecting rod slidably mounted in the cylindrical case, and a coil spring provided in the cylindrical case to outwardly urge the connecting rod so as to be contacted with the outside terminal at an end of the rod. A top end of the cylindrical case is contacted with the end of the lead.
