Voice coil loudspeaker voice coil bonding is combined into the more driving structures of multitone ring, and is set in accommodating cavity, and the positive and negative electrode of the voice coil loudspeaker voice coil is connected by external connection
Connect and realize parallel connection between multiple voice coil loudspeaker voice coils.
Wherein, the support is provided with the annular groove corresponding with Flat plate drum paper, and the Flat plate drum paper is by inserting annular
Groove is fixed on support.
Wherein, the stent outer is provided with terminal, and the terminal is electrically connected by staple line with voice coil loudspeaker voice coil.
Wherein, the terminal both ends are provided with annular flake, and the terminal tip portions are provided with square protruding, the support be provided with
The corresponding square groove of square protruding, the terminal are plugged on square groove fixed by square protruding.
The beneficial effects of the utility model are：
1. the utility model combines shape by the magnetic circuit system and voice coil loudspeaker voice coil of the setting 2 or more than 2 in support accommodating cavity
Into the more driving structures of multitone ring, multitone ring is provided with beneficial to vibration balancing, uses more driving energies to be provided for vibrating diaphragm more powerful
Driving force, raising efficiency, and the height of original loudspeaker is maintained, second and third distortion of loudspeaker is effectively reduced, frequency response curve is more
Add smooth.
2. the positive and negative electrode of voice coil loudspeaker voice coil realizes the parallel connection between multiple voice coil loudspeaker voice coils by external connection connection, when multiple voice coil loudspeaker voice coils are parallel connections,
The total impedance value of loudspeaker is changed into the half of single-tone circle impedance value, solves the problems, such as when power amplifier is to drive Low ESR as target；
Multiple voice coil loudspeaker voice coils have identical conductive characteristic, effectively prevent larger caused by the mechanical structure difference between multiple loudspeakers
Distortion, so as to obtain more preferable stereophonic effect.
