Abstract

The invention provides a sound production unit and a loudspeaker. The sound production unit comprises a basin stand, a magnetic circuit system and a vibration system, the basin stand comprises an upper cover and a lower cover, and the periphery of the upper cover is provided with a first matching wall; a magnetic gap is formed in the magnetic circuit system; the vibration system comprises a firstframework, a second framework, a voice diaphragm and a voice coil, the first framework is arranged in an annular mode, the first framework is provided with a second matching wall, an inner ring of thevoice diaphragm is fixed to an outer ring of the first framework, an outer ring of the voice diaphragm is fixed to the lower cover, the second framework is arranged in an annular mode, the second framework is fixed to the voice diaphragm, the voice coil is fixed to the second framework, and the voice coil extends into the magnetic gap. The first matching wall and the second matching wall are correspondingly arranged, so that the first framework and the upper cover have higher matching positioning precision; meanwhile, the voice diaphragm is matched with the first framework, the second framework is arranged on the voice diaphragm, the voice coil is arranged on the second framework, and the voice coil corresponds to the magnetic gap of the magnetic circuit system, so that the concentricityof the voice diaphragm and the magnetic circuit system in the whole sound production unit is ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of sounding devices, in particular to a sounding unit and a loudspeaker. 【Background technique】 [0002] The sounding unit includes a vibration system and a magnetic circuit system. Among them, the vibration system includes a sound film and a voice coil, and the voice coil is connected to the sound film; the magnetic circuit system forms a magnetic gap, and the voice coil on the sound film extends into the inside of the magnetic gap. [0003] However, in the traditional sounding unit, the concentricity between the sound film and the magnetic circuit system is poor, which affects the sound generation performance of the sounding unit, and further affects the working performance of the entire speaker. 【Content of invention】 [0004] The object of the present invention is to provide a kind of sound unit and loudspeaker; In this sound unit, the concentricity of sound film and magnetic circuit system is high;...
