TECHNICAL FIELD

[0002] The present invention relates to the field of electroacoustic assembly of electronic devices, and more particularly, to a loudspeaker assembly and an electronic device.

BACKGROUND

[0003] The loudspeaker assembly is an important component of the electronic device like a smart phone, a tablet PC, etc. The loudspeaker assembly mainly comprises a loudspeaker front case, a loudspeaker rear case and a loudspeaker vibrator. A front cavity is formed by the loudspeaker vibrator and the loudspeaker front case, and a rear cavity is formed by the loudspeaker vibrator and the loudspeaker rear case. The working performance of the loudspeaker assembly mainly depends on the volume of the front cavity and the volume of the rear cavity. Normally, the larger the volume of the rear cavity is, the better the working performance of the loudspeaker assembly is.

[0004] Along with the needs of customers, the electronic devices are becoming thinner and lighter, which makes the internal design space of the electronic device smaller and smaller. However, as the volume of the rear cavity of the loudspeaker assembly is fixed, it is difficult to obtain a larger volume from the rear cavity within the limited internal design space of the electronic device, resulting in a poor working performance of the loudspeaker assembly.

[0005] In summary, how to improve the working performance of the loudspeaker assembly in an electronic device is an urgent problem that needs to be solved by those skilled in the art.

[0024] As shown in Figs. 1-3, the loudspeaker assembly provided by embodiments of the present invention includes: a loudspeaker front case 1, a loudspeaker rear case 3, a loudspeaker vibrator 2, a deformable flexible seal bag 4, and an inlet for filling medium into the flexible seal bag 4. Wherein, a front cavity is formed by the loudspeaker vibrator 2 and the loudspeaker front case 1; a rear cavity is formed by the flexible seal bag 4, the loudspeaker rear case 3 and the loudspeaker vibrator 2; the flexible seal bag 4 and/or the loudspeaker rear case 3 are/is connected with the loudspeaker front case 1.

[0025] It can be understood that, the cavity of the flexible seal bag 4 deforms in synchronism with the outer shape of the flexible seal bag 4.

[0026] According to the loudspeaker assembly provided by the embodiment of the present invention, the deformable flexible seal bag 4 and the inlet for filling the medium into the flexible seal bag 4 are provided. Along with the filling of the medium, the flexible seal bag 4 deforms along the remaining space inside the electronic device, and fills the remaining space to the full. Since the cavity of the flexible seal bag 4 becomes larger after the flexible seal bag 4 is filled with the medium, and the rear cavity is formed by the cavity of the flexible seal bag 4, the loudspeaker rear case 3 and the loudspeaker vibrator 2, the volume of the rear cavity is effectively expanded, and the working performance of the loudspeaker assembly is improved.

[0027] Further, according to the loudspeaker assembly provided by the embodiment of the present invention, the volume of the flexible seal bag 4 is changed through changing the filling amount of the medium, thereby changing the volume of the rear cavity. The volume of the rear cavity can be adjusted according to the volume of the front cavity of the loudspeaker assembly, thereby obtaining a better working performance.

[0028] Further, in the loudspeaker assembly provided by the embodiment of the present invention, along with the filling of the medium, the flexible seal bag 4 deforms along the remaining space inside the electronic device, and fills the remaining space to the full, thereby making a full use of the remaining space inside the electronic device, reducing the design space to be occupied inside the electronic device, and providing a prerequisite for obtaining a thinner electronic device.

[0029] It should be noted that, the medium filled into the flexible seal bag 4 may be gas or other suitable filler. The specific type of the medium is not limited in the embodiments of the present invention.

[0030] In the above loudspeaker assembly, the loudspeaker front case 1 is connected with the flexible seal bag 4, and the loudspeaker front case 1 is connected with the loudspeaker rear case 3, or the loudspeaker front case 1 is connected with the flexible seal bag 4 and the loudspeaker rear case 3. Specifically, in case the loudspeaker front case 1 is connected with the flexible seal bag 4, the loudspeaker rear case 3 is connected with the flexible seal bag 4; in case the loudspeaker front case 1 is connected with the loudspeaker rear case 3, the flexible seal bag 4 is connected with the loudspeaker rear case 3; in case the loudspeaker front case 1 is connected with the flexible seal bag 4 and the loudspeaker rear case 3, the flexible seal bag 4 is connected with a part of the loudspeaker front case 1, and the flexible seal bag 4 is connected with the other part of the loudspeaker front case 1.

[0031] For the convenience of installation, preferably, the loudspeaker rear case 3 is connected with the loudspeaker front case 1, and the loudspeaker vibrator 2 is disposed between the loudspeaker front case 1 and the loudspeaker rear case 3; a first back cavity is formed by the loudspeaker vibrator 2 and the loudspeaker rear case 3, and a second back cavity is formed by the cavity of the flexible seal bag 4; the first back cavity and the second back cavity are communicated with each other and form a rear cavity.

[0032] Further, the flexible seal bag 4 is connected with the loudspeaker rear case 3. Of course, alternatively, the flexible seal bag 4 is connected with the loudspeaker front case 1, and the cavity of the flexible seal bag 4 is not communicated with the front cavity.

[0033] For the convenience of installation, as shown in Fig.1, the flexible seal bag 4 communicates with the first back cavity through a connecting pipe 5.

[0034] The relative positions of the flexible seal bag 4 and the loudspeaker rear case 3 can be designed according to the actual internal space of the electronic device. Preferably, the axial direction of the connecting pipe 5 is perpendicular to the thickness direction of the loudspeaker rear case 3.
