Package-integrable high sound quality moving coil loudspeaker structure

摘要

A package-integrable high sound quality voice coil loudspeaker structure includes a metal shell, and a diaphragm, voice coil washer, magnet, T iron and PCB packed integrally inside the metal shell; the metal shell has a cylindrical side wall and bottom wall, and a sound output is opened on the bottom wall, with a lengthened cylinder in communication with the first sound output being projected outward integrally from the bottom face of the bottom wall. Therefore, the present invention utilizing the metal shell to pack all components integrally simplifies the assembly process, and has a good waterproof performance. In addition, the configuration of the lengthened cylinder improves the sound quality.

主权项

1. A package-integrable high sound quality voice coil loudspeaker structure, characterized in that said structure comprises a metal shell, and a diaphragm, voice coil, washer, magnet, T iron and PCB (printed circuit board) packed integrally in said metal shell, wherein said metal shell has a cylindrical side wall and bottom wall in integral connection with each other, and said cylindrical side wall and bottom wall together define an accommodation chamber, said diaphragm, voice coil, washer, magnet, T iron and PCB being packed in said accommodation chamber from bottom to top in sequence; a first sound output is opened on said bottom wall; a lengthened cylinder corresponding to said first sound output is projected outward integrally from a bottom face of said bottom wall, wherein an acoustic link allowing sound to be broadcasted out is formed inside said lengthened cylinder, a start end of said acoustic link being in communication with said first sound output, a projected tail end of said lengthened cylinder being formed with a second sound output, and said acoustic link being smaller than said accommodation chamber in cross section; a top edge of said cylindrical side wall is bended inward and deformed to form a pressing unit for the strengthening of packing and positioning, a lower end of said pressing unit being propped against a upper surface of said PCB.
