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 includes an installation housing, a vibration system accommodated in the installation housing, and a magnetic circuit system that drives the vibration system to vibrate and sound and has a magnetic gap. The magnetic circuit system includes a magnetic yoke and is fixed on the magnetic The main magnetic steel on the yoke and the auxiliary magnetic steel arranged around the main magnetic steel, the vibration system includes a sound diaphragm, and the speaker also includes a The steel-connected main body and the adapter part fixed on the outer periphery of the main body, the adapter part and the main body are integrally formed, the lower end surface of the adapter part is used to fit and fix the auxiliary magnetic steel, The upper end surface of the fitting part is used for connecting with the sound-emitting diaphragm. The concentricity of the magnetic circuit inside the loudspeaker is guaranteed, and the swing (or vibration) phenomenon when the loudspeaker emits sound is improved. Meanwhile, the assembly structure of the above-mentioned main body part and the adapter part also makes the installation or assembly of the loudspeaker more convenient.

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 ...
