<p>A high quality electric-mechanical-acoustic transducer used mainly in mobile phones which is not damaged and degraded in performance by drop and impact. The transducer comprises at least one suspension (14) that supports a movable section (19) including a magnetic circuit portion (17) and a weight portion (13), and a frame (9) that supports a vibration plate (8) and the suspension (14) and defines a clearance within an elastic deformation range of the suspension (14) between the frame (9) and the outer circumference of the movable section (19). Even when the mobile terminal drops and the electric-mechanical-acoustic transducer built in it impacts, the suspension (14) can be prevented from being permanently deformed by the frame (9) receiving the outer circumference of the movable section (19).</p> |
