Abstract

The invention provides a loudspeaker unit, which includes a basin frame with a receiving space, a magnetic circuit system and a vibration system accommodated in the basin frame, the magnetic circuit system includes a lower splint and a magnet part attached to the lower splint, and the vibration system includes The upper diaphragm fixed on the pot frame, the voice coil fixed on the side of the upper diaphragm facing the magnetic circuit system, and the lower diaphragm connected to the voice coil and fixed on the pot frame, the lower splint includes the opposite first side and the connection The first side and the second side opposite to each other, the lower splint includes a notch that is recessed toward the middle area along the first side, and the lower splint includes a first side wall that bends and extends from the edge of the notch toward the lower diaphragm, The lower diaphragm is provided to avoid the opening of the first side wall. The loudspeaker unit of the present invention adopts the lower splint with special-shaped treatment and the lower diaphragm structure with openings, so that it can not only ensure the suppression effect of the lower diaphragm on the swing, but also increase the magnetic field strength of the short axis of the loudspeaker unit.

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...
