Abstract

The invention discloses a double-voice-coil loudspeaking assembly. The double-voice-coil loudspeaking assembly comprises two loudspeaking single bodies, each loudspeaking single body comprises a magnetic circuit system, a diaphragm and a voice call, the voice coil is connected with the diaphragm, the voice coil is contained in a magnetic gap of the magnetic circuit system, and openings of the magnetic gaps of the two magnetic circuit systems are arranged in an opposite manner. The invention also provides a loudspeaking apparatus with the double-voice-coil loudspeaking assembly. Based on the above scheme, according to the double-voice-coil loudspeaking assembly and the loudspeaking apparatus, high sound pressure level can be provided, and the loudspeaking loudness can be increased.

Description

technical field [0001] The invention relates to the technical field of electroacoustics, in particular to a double voice coil speaker assembly and a speaker device with the double voice coil 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. Mobile terminals require loudspeakers to have a high sound pressure level, but existing loudspeaker designs generally use a diaphragm and a voice coil, which have low electro-acoustic conversion efficiency and 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, the embodiments of the present invention provide a dual voice coil speaker assembly and a speaker device, which can improve electro-acoustic conversion efficiency, provide a hi...
