The present invention provides a sound generator. The sound generator of the present disclosure is characterized in that the front cover hollows to form the glue slot which is around and communicated with the positioning holes. After being filled into the glue slot, the glue flows into the gap between the melting point posts and the positioning holes for filling. Therefore the horizontal sway of the front cover is reduced and even avoided, and then the front cover is fixed stably. At the same time, with the gap, the glue can flow to the position between the frame and the front cover, which increases the fixing strength and stability between the front cover and the frame with the melting points as well as the tensile property of the front cover, and therefore the acoustic stability of the sound generator is further optimized.

The present invention generally relates to an apparatus and a method for obtaining a registration error map representing a level of sharpness of an image. Many methods are known which allow determining the position of a camera with respect to an object, based on the knowledge of a 3D model of the object and the intrinsic parameters of the camera. However, regardless of the visual servoing technique used, there is no control in the image space and the object may get out of the camera field of view during servoing. It is proposed to obtain a registration error map relating to an image of the object of interest generated by computing an intersection of a re-focusing surface obtained from a 3D model of said object of interest and a focal stack based on acquired four-dimensional light-field data relating to said object of interest.
