The speaker can be installed in home TVs, multimedia home audio, outdoor audio, cars, KTV venues, square broadcasts, computers, etc., as a sound unit.

[0003] The process of bouncing the cone is a key process in speaker manufacturing. The cone of the speaker is assembled by gluing. By bouncing the cone, the cone vibrates, which can improve the penetration of the glue in the center of the cone. If the glue in the center of the cone is not penetrated enough, it will cause problems such as abnormal SPL (sensitivity or sound pressure level) curve.
