Abstract

The invention provides a loudspeaker unit. The loudspeaker unit comprises a basin frame with an accommodating space, a magnetic circuit system and a vibration system that are accommodated in the basinframe; the magnetic circuit system comprises a lower clamping plate and a magnet part attached to the lower clamping plate. The vibrating system comprises an upper vibrating diaphragm fixed on the basin frame; a voice coil which is fixed on one side, facing the magnetic circuit system, of the upper vibrating diaphragm; and a lower vibrating diaphragm which is connected with the voice coil and isfixed on the basin frame; wherein the lower clamping plate comprises a first side edge arranged oppositely and a second side edge connected with the first side edge and arranged oppositely, the lowerclamping plate comprises a notch part formed by recessing towards the middle area along the first side edge, the lower clamping plate comprises a first side wall which is bent and extends towards thelower vibrating diaphragm from the edge of the notch part, and the lower vibrating diaphragm is provided with a through hole for avoiding the first side wall. According to the loudspeaker unit, the lower clamping plate subjected to special-shaped processing is matched with the lower vibrating diaphragm structure provided with the opening, so that the inhibition effect of the lower vibrating diaphragm on swinging can be ensured, and meanwhile, the magnetic field intensity of the short axis of the loudspeaker unit can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker unit in the field of electroacoustic conversion. 【Background technique】 [0002] The development of micro-speakers in the prior art tends to be ultra-thin and large Xmax applications, etc. The application of large Xmax requires high sensitivity of the speaker body and strong anti-swing ability, and the currently commonly used three-magnetic circuit SLS speaker The overall sensitivity will be lower than that of the five-magnet speaker, and the sensitivity of the current three-magnet SLS speaker needs to be improved. [0003] Therefore, it is necessary to provide a new type of three-magnetic circuit SLS loudspeaker design, which can improve the overall sensitivity while ensuring the swing of the single unit. 【Content of invention】 [0004] An object of the present invention is to provide a speaker unit capable of solving the problem of improvin...
