Abstract
Description
Technical Field
[0001] The utility model belongs to the field of manufacturing sound-generating components used for ultra-thin audio assembly, in particular to a pre-assembled loudspeaker. Background Art
[0002] With the advancement and development of science and technology, more and more media playback electronic products are moving towards multifunctionality, miniaturization, lightness, and industrialization. This has led to higher requirements for mass production of speakers. The core components of existing speakers include a ring-shaped centering frame, a voice coil, and a vibrating cone. To achieve this, the ring-shaped centering frame must first be installed inside the speaker housing. The voice coil is then attached around its inner periphery to ensure vibration stability. Finally, the vibrating cone is attached to the outer side of the upper end of the voice coil, and the outer end of the vibrating cone is elastically fixed to the outer end of the speaker housing. This completes the entire process. Typically, the ring-shaped centering frame, voice coil, and vibrating cone are bonded together using glue, making the connection process rather cumbersome. If the ring-shaped centering frame, voice coil, and vibrating cone could be pre-assembled and quickly assembled with the speaker housing, production efficiency would be greatly improved. At the same time, the position of the voice coil must be aligned with the internal ring magnet, and internal heat dissipation performance must be guaranteed. Utility Model Content
