[0002] In the occasion of screening and acoustic performance such as concert, sound system is used to play sound, and the sound system is generally equipped with high, medium and low three kinds of audio frequency range loudspeakers. In some songs played in the concert, the rhythm of these songs is relatively strong, and low-frequency loudspeakers are usually used to play, so that the audience has better auditory effect.

[0003] The sound of bass loudspeaker is mainly produced by the changing magnetic field generated by the energized coil inside, which interacts with the magnetic field of the magnet in the loudspeaker, causing the coil to vibrate in the magnetic field. The coil drives the drum paper to vibrate to push the surrounding air to vibrate, thereby generating sound. The greater the current in the coil, the greater the amplitude of the drum paper vibration, and the stronger the bass effect. The amplitude of the drum paper vibration is generally related to the magnetic force of the coil after energization, the material of the drum paper and the surface area of the drum paper. However, in some songs with strong rhythm, it is necessary to improve the bass intensity of the bass loudspeaker.
