MULTIFUNCTIONAL SPEAKER WITH DEFORMATION PREVENTION STRUCTURE

摘要

The present invention pertains to a multifunctional speaker with a structure that may prevent deformation due to external impact. The disclosed invention includes a hollow frame, a front cover coupled with a front surface portion of the frame, a rear cover coupled with the rear surface portion of the frame, a vibration plate mounted in the frame and coupled with a voice coil, and a vibrator vibrating in the frame, wherein the rear cover is made from a metal material and inserted into the frame to be coupled therewith. According to the multifunctional speaker with the deformation prevention structure of the present invention as above, the rear cover is made from a metal material in which the material rigidity is increased, thereby increasing the deformation prevention effects of the parts due to external impact. In addition, because the insertion structure of the rear cover is in the frame, the degree of close contact of the rear cover and the frame is improved by the repulsive force of the folded portions, thereby increasing the structural rigidity. Therefore, it is possible to control the shape deformation in axial and circumferential directions due to external impact.
