TECHNICAL FIELD

[0001] The utility model relates to low frequency loudspeaker technical field, concretely is a low frequency loudspeaker concave-convex type spider. BACKGROUND

[0002] In the technical field of spider and loudspeaker, the spider, as an important component of the loudspeaker magnetic circuit system, plays a crucial role. The spider, usually located between the magnet and the front plate of the loudspeaker, not only bears the structural stability of the magnetic circuit system, but also directly affects the distribution of the magnetic field and the transmission efficiency of the sound. Especially in low frequency loudspeakers, since it needs to handle lower frequency sound signals, higher requirements are put forward for the design of the spider. An ideal spider design should be able to effectively focus the magnetic field, improve the efficiency and sound quality of sound transmission, while maintaining the lightness and stability of the structure, to meet the dual pursuit of high performance and aesthetics of modern sound products. Therefore, developing a spider that can meet the sound quality requirements and achieve lightweight design has become an important direction for the development of low frequency loudspeaker technology.

[0003] However, the traditional low frequency loudspeaker spider design mostly adopts a flat plate structure, which has obvious limitations in dealing with the special needs of low frequency loudspeakers. On the one hand, the flat plate spider is difficult to achieve ideal focusing effect in the magnetic field distribution, resulting in limited sound transmission efficiency and suboptimal sound quality. On the other hand, in order to ensure the stroke of the low frequency loudspeaker, the traditional design often needs to increase the axial length of the spider and other components, which undoubtedly increases the thickness of the entire loudspeaker, which is contrary to the current market trend of lightweight. In addition, the flat plate spider is prone to deformation when subjected to the force generated by the loudspeaker vibration for a long time, affecting the stability of the sound quality and the service life of the loudspeaker. These shortcomings of traditional technology not only limit the further improvement of the performance of low frequency loudspeakers, but also affect the overall design aesthetics and user experience of sound products. Therefore, a new type of low frequency loudspeaker spider design is needed to overcome the above limitations and promote the continuous development of low frequency loudspeaker technology. For this purpose, we propose a low frequency loudspeaker concave-convex type spider. SUMMARY
