Problems solved by technology

When the traditional loudspeaker is assembled with the magnetic bowl and the main magnetic steel, the magnetic bowl needs to be fixed with an additional splint, which is not only difficult to assemble, but also prone to assembly errors during assembly of the splint, which affects the concentricity of the magnetic circuit system , so that the speaker is prone to vibration and swing when making sound

Abstract

The invention provides a loudspeaker. The loudspeaker comprises an installation shell, a vibration system accommodated in the installation shell and a magnetic circuit system which drives the vibration system to vibrate and produce sound and is provided with a magnetic gap, and the magnetic circuit system comprises a magnet yoke, main magnetic steel fixedly arranged on the magnet yoke and auxiliary magnetic steel arranged around the main magnetic steel. The vibration system comprises a sounding diaphragm, the loudspeaker further comprises a main body part which is used for covering the main magnetic steel and is connected with the main magnetic steel and an adaptive part which is fixedly arranged at the periphery of the main body part, the adaptive part and the main body part are integrally formed, the lower end surface of the adaptive part is used for being attached and fixed with auxiliary magnetic steel, and the upper end surface of the adaptive part is used for being connected withthe sounding diaphragm. The concentricity of the internal magnetic circuit of the loudspeaker is ensured, the swing (or vibration) phenomenon of the loudspeaker during sound production is improved, and meanwhile, the loudspeaker is more convenient to install or assemble due to the assembly structure of the main body part and the adaptive part.

Description

【Technical field】 [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker. 【Background technique】 [0002] The loudspeaker includes a vibration system and a magnetic circuit system. The magnetic circuit system has a magnetic gap, and the magnetic circuit system includes a magnetic bowl and a main magnet, that is, the magnetic bowl cover is set outside the main magnet, and the vibration system uses a voice coil to place in the magnetic gap. At this time, after power on, The voice coil vibrates in the magnetic gap of the magnetic circuit system at different frequencies, thereby realizing the vibration and sound of the vibration system. When the traditional loudspeaker is assembled with the magnetic bowl and the main magnetic steel, the magnetic bowl needs to be fixed with an additional splint, which is not only difficult to assemble, but also prone to assembly errors during assembly of the splint, which affects the concentricity of ...
