The invention discloses a micro dual-drive loudspeaker. The micro dual-drive loudspeaker comprises a loudspeaker main body frame, dual-drive coils, dual-drive magnetic circuit systems and a vibratingdiaphragm, wherein two mounting grooves are formed in the loudspeaker main body frame, the dual-drive coils and the dual-drive magnetic circuit systems are mounted in the mounting grooves separately,the vibrating diaphragm is correspondingly arranged on the dual-drive coils and the dual-drive magnetic circuit systems in a covering manner, and two ends of the vibrating diaphragm are connected withtwo ends of the loudspeaker main body frame. On the basis that the size of an original single-drive loudspeaker is not changed, the dual-drive magnetic circuit systems are adopted, the size of spaceof the loudspeaker is effectively controlled, the boost pressure of the loudspeaker is increased, the electrical-acoustic transformation efficiency of the loudspeaker is improved, and distortion of the loudspeaker is reduced.
Description
Technical field [0001] The invention relates to the field of loudspeakers, in particular to a miniature dual-drive loudspeaker. Background technique [0002] Generally, electro-acoustic transducers are acoustic output devices, such as speakers, receivers, buzzers, and vibrators, which convert electrical signals input from a signal source into mechanical signals to output sound or generate vibrations, earphones and speakers The system is a representative example of using this type of acoustic output device. [0003] The existing speaker has only one magnetic circuit system, which results in extremely low electro-acoustic conversion efficiency of the micro speaker, high resonance frequency, high distortion, and low sound pressure. Summary of the invention [0004] In view of the above shortcomings, the purpose of the present invention is to provide a miniature dual-drive speaker, which adopts a dual-drive magnetic circuit system on the basis of the original single-drive speaker witho...
