Loudspeaker module

Abstract

The invention discloses a loudspeaker module which comprises a shell and a single loudspeaker. A cavity for fixedly containing the single loudspeaker is formed in the shell, the cavity is divided into a front sound cavity and a rear sound cavity by the single loudspeaker, a sound outlet hole is formed in the shell, the front sound cavity is communicated with the sound outlet hole, a partition plate is arranged in the rear sound cavity and matched with the shell to separate an independent cavity from the rear sound cavity, the independent cavity is filled with sound absorption particles, and a through hole penetrating the partition plate is formed in the partition plate. The loudspeaker module is simple in structure and overcomes the shortcoming that the sound absorption particles enter the single loudspeaker along with airflow, the number of the sound absorption particles is increased, sound absorption effects are improved, and the acoustic performance of the loudspeaker module is improved.

Description

technical field [0001] The invention relates to the field of electro-acoustics, in particular to a speaker module. Background technique [0002] With the expansion of the consumer electronics market, a large number of consumer electronics products such as mobile phones and notebook computers have been widely promoted, and speaker modules have been widely used as important acoustic components in consumer electronics products. As people pay more and more attention to the acoustic effects of consumer electronic products, the acoustic performance of speaker modules has also attracted more and more attention in the industry. [0003] At present, in order to improve the acoustic performance of the SPK module, sound-absorbing particles are installed in the module cavity. In order to prevent the sound-absorbing particles from entering the unit with the gas flow inside the module cavity, in the existing speaker module, the sound-absorbing particles are packaged by mesh cloth and the...

AI Technical Summary

Problems solved by technology

In order to prevent the sound-absorbing particles from entering the interior of the monomer with the flow of gas in the module cavity, the sound-absorbing particles of the existing speaker module will be packaged through mesh cloth and then loaded into the sound cavity. This structure, although it solves the problem of sound-absorbing particles entering The internal problem of the monomer, but due to the limitation of the shape of the sound-absorbing particle packaging structure, the sound-absorbing particles cannot fully and effectively fill the sound cavity after the sound-absorbing particles are placed in the sound cavity, so that the filling quantity is limited by the shape of the module sound cavity. At the same time, the mesh cloth that encapsulates the sound-absorbing particles It will also hinder the contact between the sound-absorbing particles and the gas inside the sound cavity, weakening the effect of the sound-absorbing particles

[0004] Therefore, it is necessary to provide a simpler and low-cost structure to solve the problem of bulk sound-absorbing particles moving with the airflow inside the sound cavity and entering the sound cavity, so as to maximize the effect of sound-absorbing particles
