Description

Technical Field

[0001] The utility model relates to the technical field of audio components, in particular to a novel bass speaker component. Background Art

[0002] In a subwoofer, the magnetic field effect and stroke length play a decisive role in the sound quality and audio performance.

[0003] First of all, the magnetic collection effect has a crucial impact on the sound quality of the woofer. When the magnetic field of the electromagnet is concentrated and strong, the electromagnetic force on the coil in the magnetic field is also greater, which can drive the speaker film to produce a larger amplitude and produce a deeper and more powerful sound. This magnetic collection effect can significantly improve the low-frequency response ability of the woofer, making the bass fuller and more powerful, and the sound quality purer.

[0004] Secondly, stroke is also one of the important factors that affect the sound quality and audio performance of the subwoofer. The stroke refers to the maximum vibration displacement of the speaker film under the action of electromagnetic force, which determines the lowest frequency and maximum volume that the speaker can emit. For subwoofers, since they need to emit lower frequency sounds, they need a longer stroke to ensure the complete restoration of low-frequency signals.

[0005] Therefore, when designing and manufacturing a woofer, it is necessary to fully consider the two factors of magnetic collection effect and stroke. In the prior art, since the one-piece kick iron needs to be cast in one piece, the carbon content is high and the magnetic conductivity is poor. The split kick iron has poor contact surface adhesion, resulting in poor magnetic conductivity. Therefore, it is necessary to provide a speaker assembly with good magnetic conductivity and longer stroke. Utility Model Content
