Abstract (en)

[origin: EP3432600A1] Disclosed in the present invention are a loudspeaker assembly and an electronic device. The loudspeaker assembly comprises a loudspeaker front case, a loudspeaker oscillator, a loudspeaker rear case, a deformable flexible seal bag, and an inlet for filling medium into the flexible seal bag; wherein the loudspeaker oscillator and the loudspeaker front case form a front cavity, while the flexible seal bag, the loudspeaker rear case and the loudspeaker oscillator form a rear cavity. Along with filling of medium, the flexible seal bag in the loudspeaker assembly deforms along a remaining space in an electronic device and fills the remaining space to the full. A cavity of the flexible seal bag increases in size after being filled with the medium, and a rear cavity is formed by the cavity of the flexible seal bag, the loudspeaker rear case and loudspeaker oscillator, therefore a volume of the rear cavity is expanded, thereby improving work performances of the loudspeaker assembly. The electronic device disclosed in the present invention is provided with the above-described loudspeaker assembly.
