Abstract:
A non-dispensing manufacturing process includes forming a paper cone; engaging the paper cone with a voice coil to form a vibration assembly; fixing a yoke, a magnet set, and a washer to form a magnetic circuit assembly; engaging a basket with the magnetic circuit assembly; and engaging the basket with the vibration assembly to form a speaker, where no glue is used in the manufacturing process. A speaker includes a paper cone; a voice coil engaged with the paper cone to form a vibration assembly, where a junction between a bobbin of the voice coil and the paper cone has a first welding layer; a magnetic circuit assembly including a yoke, a magnet set, and a washer that are integrally fixed; and a basket engaged with the magnetic circuit assembly and the vibration assembly.
