Abstract

The invention discloses a double-diaphragm loudspeaker module, which comprises two loudspeaker monomers, wherein each loudspeaker monomer comprises a magnetic circuit system, a diaphragm and a voice coil; each voice coil is connected to the corresponding diaphragm, each voice coil is contained in a magnetic gap of the corresponding magnetic circuit system, and openings of the magnetic gaps of the two magnetic circuit systems are oppositely arranged. The invention also provides a loudspeaker device provided with the double-diaphragm loudspeaker module. According to the scheme, the higher sound pressure level can be provided to help improve the loudspeaker volume.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a double-diaphragm speaker assembly and a speaker device with the double-diaphragm speaker assembly. Background technique [0002] At present, the loudspeaker, as an important component of a mobile terminal with a voice playback function, has been widely used. The mobile terminal requires the loudspeaker to have a high sound pressure level, and the existing loudspeaker design generally uses a diaphragm, which has a limited ability to increase the sound pressure level (loudness). Therefore, it is necessary to propose a loudspeaker design that can effectively improve the sound pressure level. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a dual-diaphragm speaker assembly and a speaker device, which can provide a higher sound pressure level and help improve the loudness of the speaker. [0004] A dual-diaphragm speak...
