Abstract

The present invention belongs to the technical field of electroacoustic conversion, and provided is a loudspeaker. The loudspeaker comprises a base, a vibration system and a magnetic circuit system that drives the vibration system to generate sound; the vibration system comprises a vibrating diaphragm assembly and a voice coil; the magnetic circuit system comprises a first magnetic guide block disposed inside of the base, a main magnetic assembly fixed on the first magnetic guide block, a sub-magnetic assembly fixed on the first magnetic guide block and arranged encircling the periphery of the main magnetic assembly, and a second magnetic guide block that covers the main magnetic assembly and the sub-magnetic assembly, a magnetic gap being formed between the main magnetic assembly and the sub-magnetic assembly, and the voice coil being placed in the magnetic gap. The main magnetic assembly, the sub-magnetic assembly and the first magnetic guide block constitute a first magnetic circuit traversing the magnetic gap; the main magnetic assembly, the sub-magnetic assembly and the second magnetic guide block constitute a second magnetic circuit traversing the magnetic gap; and the magnetic circuit direction of the first magnetic circuit is opposite to that of the second magnetic circuit. The first magnetic circuit and the second magnetic circuit of the present invention may greatly enhance the magnetic field strength of the magnetic gap where the voice coil is located so as to obtain good acoustic performance.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker. 【Background technique】 [0002] With the rapid development of science and technology, the penetration rate of speakers is getting higher and higher. People's requirements for speakers are not limited to the playback of video and audio, but also have higher requirements for the sound quality and reliability of the sound played by speakers. Speakers are directly related to The sound quality of the playback sound is good or bad and the stability of the product. [0003] In traditional loudspeakers, the magnetic circuit of the magnetic circuit system has a low magnetic field strength in the magnetic gap formed between the main magnet and the secondary magnet, resulting in poor acoustic performance. 【Content of invention】 [0004] The object of the present invention is to provide a loudspeaker aimed at solving the problem of poor acoustic perform...
