Title:
LOUDSPEAKER MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/045660
Kind Code:
A1
Abstract:
The present application provides a loudspeaker module and an electronic device. The loudspeaker module comprises a first loudspeaker and a second loudspeaker; the first loudspeaker comprises a first magnetic circuit assembly, a first voice coil, and a first diaphragm assembly; the first magnetic circuit assembly comprises a first magnetic conductive yoke and a first magnet; the first voice coil is arranged around the first magnet and is connected to the first diaphragm assembly; the second loudspeaker and the first loudspeaker are stacked in opposite directions; the second loudspeaker comprises a second magnetic circuit assembly, a second voice coil, and a second diaphragm assembly; the second magnetic circuit assembly comprises a second magnetic conductive yoke and a second magnet; the second voice coil is arranged around the second magnet and is connected to the second diaphragm assembly; and magnetic pole directions of the magnetic circuits of the first magnet and the second magnet are consistent. The loudspeaker module forms a magnetic current loop, the magnetic fields of the first magnet and the second magnet are superimposed on each other, so that the magnetic flux density is increased, and the utilization efficiency of the magnetic circuits in the loudspeaker module is improved.
