Method for replacing foam edge of loudspeaker

Abstract

The invention discloses a method for replacing a foam edge of a loudspeaker. The method comprises the following steps of: 1, observing the diameter, size, width, thickness, hardness and foam particle density of the foam edge, and buying a new foam edge; 2, removing the damaged foam edge, and using a sharp knife as an auxiliary tool to cut off adhesive parts along the periphery of a voice coil; 3, diluting dust-free rag with xylene or a cleanser, cleaning an adhesive surface on the loudspeaker, and keeping the adhesive surface dry; 4, adjusting the position of the voice coil on a central magnetically conductive iron column, and rotating the voice coil again for fixation; 5, pasting textured paper on the periphery of the adhesive surface, so as to prevent glue from contaminating other parts of the loudspeaker; and 6, uniformly applying the special glue for foam whose main component is synthetic resin to the adhesive surface and the new foam edge, bonding the new foam edge and the adhesive surface after determining that the glue is 80 percent dry through finger touch, applying a slight force, and waiting for 20 minutes before the new foam edge is ready for use. The replacement method provided by the invention has the advantages that the foam edge can be replaced by a user himself, the replacement is convenient, the operation is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a method for replacing foam edges of loudspeakers. Background technique [0002] At present, many speakers are foam edge speakers, the bass is fluffy and soft, quite comfortable, the lower limit frequency of the bass is relatively low, and the bass dive is better; but the foam edge is easy to age and has a short life, so it often needs to be replaced, and it is too much to send to a repair shop for replacement. Troublesome and expensive. Contents of the invention [0003] The object of the present invention is to provide a method for replacing the foam edge of a loudspeaker aiming at the defects and deficiencies of the prior art. [0004] For realizing the above object, the technical scheme that the present invention adopts is: it comprises the steps: [0005] 1. Observe the diameter, size, width, thickness, hardness, and density of foam particles of the foam edge, and p...
