PROBLEM TO BE SOLVED: To provide an electroacoustic transducer with an increased shock resistance. SOLUTION: An electroacoustic transducer 1 includes a displacement restriction portion 14 in the surface direction having a cylinder shape extending from an upper face of an upper case 11 to a circumference of an edge face of a magnetic piece 47. This displacement restriction portion 14 on a surface direction restricts the magnetic piece 47 to displace in the surface direction when a shock caused by falling or the like is applied to the electroacoustic transducer 1. With this, a vibration plate 46 is prevented from buckling, and the shock resistance of the electroacoustic transducer 1 can be increased. COPYRIGHT: (C)2004,JPO
