Loudspeaker assembly and electronic device
Provided are a loudspeaker assembly and an electronic device. The loudspeaker assembly includes: a housing having an internal cavity; a loudspeaker unit built in the internal cavity and including a loudspeaker diaphragm; and a separator provided in the internal cavity, the internal cavity being divided by the separator and the loudspeaker unit into a first cavity and a second cavity; where the housing has a through hole, the first cavity communicates with an exterior of the housing by the through hole, and the loudspeaker diaphragm is positioned in the first cavity; and the separator is provided with a balance hole in communication with the first cavity, and the second cavity is in communication with the first cavity through the balance hole.
1. A loudspeaker assembly, applied to an electronic device, comprising:
a housing having an internal cavity;
a loudspeaker unit built in the internal cavity and including a loudspeaker diaphragm; and
a separator provided in the internal cavity, the internal cavity being divided by the separator and the loudspeaker unit into a first cavity and a second cavity;
wherein the housing has a through hole, the first cavity communicates with an exterior of the housing by the through hole, and the loudspeaker diaphragm is positioned in the first cavity;
and the separator is provided with a balance hole in communication with the first cavity, and the second cavity is in communication with the first cavity through the balance hole, wherein the balance hole is covered with a water-proof membrane to control an amount of air allowed into the second cavity.
2. The loudspeaker assembly according to claim 1 , wherein the separator comprises first separator member and a second separator member, the balance hole is provided on the first separator member and/or the second separator member;
the first separator member has a first end attached to an inner side wall of the housing facing away from the loudspeaker diaphragm, and the first separator member has a second end attached to the loudspeaker unit; and
the second separator member has a first end attached to an inner side wall of the housing facing the loudspeaker diaphragm, and the second separator member has a second end attached to the loudspeaker unit.
3. The loudspeaker assembly according to claim 2 , wherein when the balance hole is provided on the first separator member, the loudspeaker unit divides the second cavity into a first sub-cavity and a second sub-cavity, and the first sub-cavity communicates with the second sub-cavity through a communication channel.
4. The loudspeaker assembly according to claim 2 , wherein the first separator member and the second separator member are injection molded structures.
5. The loudspeaker assembly according to claim 2 , wherein the first separator member and/or second separator member provided with the balance hole has an L shape.
6. The loudspeaker assembly according to claim 1 , wherein the loudspeaker assembly is a side sound-emission loudspeaker assembly.
7. An electronic device, comprising the loudspeaker assembly according to claim 1 , wherein a sound-outlet hole is opened on a casing of the electronic device, and the through hole on the housing of the loudspeaker assembly is arranged opposite to the sound- outlet hole.
