PROBLEM TO BE SOLVED: To provide a speaker device in which oscillation distortion does not occur and thus sound volume can be secured even when strong vibration occurs from an oscillation device, so that clear sounds in a broad sound area can be output from the speaker device.SOLUTION: In a speaker device 1, a vibration device 3 is provided to a radiation plate formed of a full hard plate material. Vibration occurring at the vibration device is transmitted to the radiation plate 2, and radiated as sounds from the radiation plate. An end portion of a transmission rod 4 of the vibration device which comes into contact with the radiation plate and transmits the vibration of the vibration device to the radiation plate is formed like a convex curved surface. The speaker device is provided with urging means 5 for applying predetermined press force to the contact point of the contact portion between the transmission rod having the end portion shaped like the convex curved surface of the vibration device and the radiation plate, thereby bringing the transmission rod into contact with the radiation plate. The speaker device is provided with adjusting means for adjusting the urging force of the urging means.SELECTED DRAWING: Figure 1 |
