Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0037] In addition, if there are descriptions involving "first", "second" and ...

Abstract
The invention discloses a loudspeaker module which comprises a module shell with a containing space and a loudspeaker monomer contained in the module shell, the loudspeaker monomer divides the containing space into a front sound cavity and a rear sound cavity, and the rear sound cavity is filled with sound absorption particles; the module shell is provided with an air suction hole which is communicated with the rear sound cavity and is used for sucking air outwards; the module shell comprises a shell bottom wall and a shell side wall connected with the periphery of the shell bottom wall, the shell bottom wall comprises an outer surface and an inner surface, the shell side wall comprises an inner wall surface, and the air suction hole comprises a concave hole which is at least formed in the direction from the shell side wall to the inner surface along the outer surface in a concave mode. A height difference exists between the hole bottom surface of the concave hole and the inner surface, and the inner wall surface of the shell side wall is provided with an opening which is communicated with the concave hole and the rear sound cavity. The loudspeaker module provided by the invention is better in acoustic performance and lower in production cost.
Description
technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker module. Background technique [0002] The loudspeaker module is an acoustic-electric transducer device that can produce sound through the conversion of electrical signals. At present, it is widely used in electronic equipment, such as speakers of mobile electronic terminals such as mobile phones, tablet computers, and notebooks. With the development of market consumption, the advancement of product design and production and processing technology, electronic equipment is becoming more and more miniaturized and thinner, which requires the speaker module to be more and more miniaturized to meet the needs of electronic products. [0003] In the prior art, sound-absorbing particles are filled in the rear acoustic cavity of the speaker module as an effective means to increase the volume of the rear acoustic cavity by equivalently increasing the F0 of t...
