One Magnet 410, the arrangement regulation of the second Magnet 420 are arranged.First strengthens Magnet 430 and the first Magnet 410 and the second Magnet 420
Be respectively positioned on the homonymy of vibrating diaphragm 200, the first reinforcement Magnet 430 be disposed side by side on the first adjacent Magnet 410 and the second Magnet 420 it
Between, a kind of embodiment is all provided between first Magnet 410 and the second Magnet 420 of a unit group and between unit group
Put the first reinforcement Magnet 430.
Refering to Fig. 4, when tone currentss are from a certain straightway 310 of flowing through coil conductor in paper extroversion paper, second
Magnet 420 is located at the S poles of the left side of the first Magnet 410, the N poles of the first Magnet 410 and the second Magnet 420 respectively close to vibrating diaphragm
200 sides, magnetic field line is from the N poles of the first Magnet 410 and arrives at the S poles (magnetic direction is to the left) of the second Magnet 420, together
When, first strengthens the N of Magnet 430 extremely near the first Magnet 410, and first strengthens the S of Magnet 430 extremely near the second Magnet 420, magnetic
Field wire is strengthened the N poles of Magnet 430 from first and arrives at the S poles (magnetic direction is equally to the left) of the first reinforcement Magnet 430, in
Near the side of vibrating diaphragm 200, due to the first effect for strengthening Magnet 430, first strengthens the magnetic field of Magnet 430 and the first Magnet
410 and second the magnetic field formed between Magnet 420 into positively related synergistic effect, the magnetic field intensity in the magnetic field residing for coil-conductor
Significantly strengthen, coil layer 300 drives the driving force increase of vibrating diaphragm 200, the amplitude increase of vibrating diaphragm 200, the sound pressure level (sound of loudspeaker
Amount) improve.According to left hand rule, the straightway 310 vibrates upwards.
Refering to Fig. 4, when tone currentss from paper to a certain straightway 310 of flowing through coil conductor outside paper when, i.e., when
From after a certain straightway 310 of flowing through coil conductor in paper extroversion paper, tone currentss continue to flow through linkage section to tone currentss
320, and when flowing through nearest with such as front a certain straightway 310 parallel a certain straightway 310, the second Magnet 420 is located at first
The S poles of the right of Magnet 410, the N poles of the first Magnet 410 and the second Magnet 420 respectively close to 200 side of vibrating diaphragm, magnetic field line from
The N poles of the first Magnet 410 are set out and arrive at the S poles (magnetic direction is to the right) of the second Magnet 420, meanwhile, first strengthens Magnet 430
N extremely near the first Magnet 410, first strengthens the S of Magnet 430 extremely near the second Magnet 420, and magnetic field line strengthens Magnet from first
430 N poles are set out and arrive at the S poles (magnetic direction is equally to the right) of the first reinforcement Magnet 430, in the side of close vibrating diaphragm 200,
Due to the first effect for strengthening Magnet 430, first strengthens between the magnetic field of Magnet 430 and the first Magnet 410 and the second Magnet 420
The magnetic field of formation significantly strengthens into positively related synergistic effect, the magnetic field intensity in the magnetic field residing for coil-conductor, and coil layer 300 is driven
The amplitude increase formed by dynamic vibrating diaphragm 200, the sound pressure level (volume) of loudspeaker are improved.According to left hand rule, the straightway 310 is same
Vibrate upwards.
Therefore, being crisscross arranged by the first Magnet 410 and the second Magnet 420, just changes adjacent first Magnet, 410 He
Second Magnet 420 magnetic direction between the two, meanwhile, first strengthens the N of Magnet 430 extremely near the first Magnet 410, and first adds
Extremely near the second Magnet 420, the reinforcement magnetic direction that the first reinforcement Magnet 430 is produced accordingly changes to be formed the S of strong magnet 430
Positively related synergistic effect, under the collective effect in two kinds of magnetic fields so that adjacent two sections of senses of current are contrary on coil-conductor
The direction of the vibration of straightway 310 is consistent, finally so that 300 synchronous vibration of whole coil-conductor and coil layer.
