Document Type and Number:
WIPO Patent Application WO/2018/218766
Kind Code:
A1
Abstract:
A loudspeaker module and an electronic device. The module comprises a module housing and a loudspeaker unit (13); a cavity is provided inside the module housing, and the loudspeaker unit (13) is provided in the cavity; the loudspeaker unit (13) divides the cavity into a front sound cavity (20) and a rear sound cavity (21); inner core sound holes (14) of the loudspeaker unit (13) are in communication with the rear sound cavity (21); the module further comprises a shielding portion which is configured to partially or entirely shield the inner core sound holes (14). A technical problem to be solved is that the size of the inner core sound holes (14) of an existing loudspeaker module is fixed and cannot be adjusted according to loudspeaker modules of different models. The size of the inner core sound holes (14) is adjusted by means of the shielding portion, so that the same loudspeaker unit (13) can be applied to different loudspeaker modules, simplifying the design process of the loudspeaker unit (13) and improving the universality of the loudspeaker unit (13).
