US 2014/0369546 A1 · Loudspeaker and Manufacturing Method Therefor

Abstract

The present invention relates to a speaker box module, and particularly relates to a loudspeaker that produces sound through the mechanical vibration generated by electromagnetic force and a manufacturing method therefor. The loudspeaker comprises a speaker box module which comprises a speaker, a passive radiator and a speaker box panel, wherein a mounting hole is arranged in the speaker box panel; the speaker is arranged in the mounting hole and is integrated with the speaker box panel by means of insert injection molding; a secondary mounting hole is arranged in the speaker box panel at one side of the mounting hole; and the passive radiator is arranged in the secondary mounting hole and is integrated with the speaker box panel by means of insert injection molding. The loudspeaker is small and thin, structurally simple, and enhances bass, and can be used as a built-in speaker or an external speaker for modern tablet computers or smart phones, and the like. In order to ensure that the speaker box has excellent acoustic effect, the present invention uses an insert injection integrated manufacturing process, which ensures maximum acoustic effect of the speaker box while greatly reducing man-hours and thereby increasing production efficiency.

Dependent claims

A loudspeaker, comprising a speaker box module, wherein said speaker box module comprises a speaker, a passive radiator and a speaker box panel, wherein said speaker box has a mounting hole provided therein, said speaker is provided in said mounting hole and integrated with said speaker box panel by means of insert injection molding;

a secondary mounting hole is arranged in said speaker box panel at one side of said speaker box panel, wherein said mounting hole is provided;
and said passive radiator is arranged in said secondary mounting hole and is integrated with said speaker box panel by means of insert injection molding.

A manufacturing method for loudspeaker, comprising the following steps:

a) molding integrally a vibrating diaphragm of a speaker, a surround and an outer frame by injecting to define a vibrating cone paper;
b) putting a weighting block in a mold, covering rubber material on said weighting block by an injection process to define a rubber surround and a passive radiator connected with said rubber surround, at the same time;
c) putting said vibrating cone paper and said passive radiator in a mold for said speaker box panel, making said speaker box panel by an insert injection molding, wherein said vibrating cone paper, said passive radiator and said speaker box panel are integrally molded to define an integrated structure by an insert injection so as to define a speaker box panel module with a vibrating cone paper and a passive radiator;
d) putting magnetic circuit components of said speaker and making them define an integrated structure by an insert injection in a mold so as to define a magnetic circuit system;
e) assembling said magnetic circuit system and said vibrating cone paper, and fitting said magnetic circuit system and said vibrating cone paper together in said speaker box panel by fastening, locking screws, ultrasonic wave or hot melting so as to define a speaker box module with a speaker having a complete structure;
f) preparing a back chamber body matching said speaker box panel by a special injection molding;
g) mounting said whole speaker box module in a back chamber and make said speaker box module fit said back chamber completely, and making said speaker box module be integrated with said speaker box panel so as to define a speaker box module with a back chamber, which has a complete structure;
h) assembling said whole speaker box module on a frame and fastening said speaker box module on a frame by a bolt.
