Document Type and Number:
WIPO Patent Application WO/2024/007509
Kind Code:
A1
Abstract:
Disclosed in the present invention are a dual-diaphragm sound receiver and an electronic device. The dual-diaphragm sound receiver comprises a housing assembly, a first diaphragm assembly, a second diaphragm assembly, an armature and an electromagnetic drive device. An inner cavity is divided by the first diaphragm assembly and the second diaphragm assembly into a first front cavity, a second front cavity, and a rear cavity located between the first front cavity and the second front cavity. The armature is arranged in the rear cavity, and comprises a first moving sheet and a second moving sheet, which are arranged opposite each other, wherein the first moving sheet and the second moving sheet are each suspended at one end; the first moving sheet is connected to the first diaphragm assembly in a driving manner, and the second moving sheet is connected to the second diaphragm assembly in a driving manner; the electromagnetic drive device is arranged in the rear cavity, and is connected to the housing assembly; and both the first moving sheet and the second moving sheet are arranged in the electromagnetic drive device in a penetrating manner, and are driven by the electromagnetic drive device to vibrate. The dual-diaphragm sound receiver of the present invention having two diaphragm assemblies for vibration and sound production has higher sound pressure output, and has small vibration during operation to work more stably.
