摘要： A loudspeaker apparatus includes an acoustic diaphragm; a support member having a housing, which is a hole in a surface of the support member facing the acoustic diaphragm; a magnetostrictive actuator having a magnetostrictor and a drive rod coupled to an end of the magnetostrictor, the magnetostrictive actuator being inserted into the housing such that the drive rod contacts the acoustic diaphragm, the magnetostrictive actuator applying vibration to the acoustic diaphragm; and a spring inserted into the housing from a position opposite to a position of the drive rod of the magnetostrictive actuator, the spring pressing the magnetostrictive actuator toward the acoustic diaphragm and applying a load to the magnetostrictor.
