Low-frequency loudspeaker case device and production process

Abstract

The invention relates to the technical field of a loudspeaker case, in particular to a low-frequency loudspeaker case device and a production process. A plurality of insertion rods are uniformly distributed on the outer side of the bottom surface of an upper cover; a clamp edge is arranged on the outer side surface of the bottom end of each insertion rod; a plurality of flanges matched with the insertion rods to be used are arranged on the upper side surface of a main body; an insertion groove in which the corresponding insertion rod is inserted is formed in each flange; in addition, a hollowing part matched with the clamp edge to be used is formed in the bottom end of each insertion groove; a plurality of first support frames are arranged on the top surface of the upper cover; a first baffle plate is arranged on the top surface of each first support frame; eight first sound producing holes are formed in each of the first baffle plates; second baffle plates matched with the first baffle plates to be used are arranged on the bottom surface of the main body in an eccentric way; five second sound producing holes are formed in the second baffle plates; third baffle plates are arranged on the main body positioned at the outer sides of the second sound producing holes. Therefore the low-frequency loudspeaker case device has the advantages that the bass sound effect of a small-dimension loudspeaker is improved; the bass sound pressure is increased; the welding sheet sealing effect of a loudspeaker is ensured.

Description

technical field [0001] The invention relates to the technical field of loudspeaker shells, in particular to a low-frequency loudspeaker shell device and a production process. Background technique [0002] At present, the small-sized speakers on the market have poor bass effects, and the shells assembled with them are more or less deficient in terms of bass effects, sealing, ease of assembly, and ease of connection; In the use environment, it cannot effectively resist external corrosion for a long time and keep the appearance of the product unchanged. Contents of the invention [0003] The purpose of the invention is to improve the bass sound effect of small-sized speakers, increase the sound pressure of the bass, and ensure the low-frequency speaker shell device and production process of the soldering pieces of the speaker to be sealed. [0004] Technical scheme of the present invention is as follows: [0005] The low-frequency loudspeaker shell device includes an upper ...
