  • Patent number: 10820075
    Abstract: 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.
