<p>When an electroacoustic transducer having a vibration function is continuously operated, there are drawbacks that a phenomenon that a natural vibration frequency (f0) of mechanical vibration is changed occurs, and thus, the mechanical vibration is reduced, and reliability is lost. The electroacoustic transducer having a vibration function is provided with a fame, a vibration plate fixed to the frame, a voice coil fixed to the lower side of the vibration plate, and a suspension which is fixed to the frame and supports a magnetic circuit unit so as to be movable in up and down directions, wherein the suspension is fixed to the frame through a buffer member.</p> |
