Abstract

The present invention comprises: a first magnet in which the S pole and the N pole are horizontally arranged relative to a first plate and a second plate; and a second magnet in which the N pole and the S pole are horizontally arranged relative to the second plate and a third plate. Thus, since the strength of magnetic fields generated from the first magnet and the second magnet becomes larger, the operation efficiency may be improved. Further, magnetized areas of the first magnet and the second magnet are increased, thereby preventing the first magnet and the second magnet from being bent or damaged during the magnetization process of the first magnet and the second magnet.

The ribbon itself becomes a diaphragm to directly generate sound by flowing a current of a voice signal through the dedicated transformer to the ribbon diaphragm. It is used for high or ultra high sound because it can make the weight of vibration system such as vibration plate light.

One of them is generated by the magnet unit 140, and the other is formed by the current flowing through the voice coil 130. At this time, the strength of the magnetic field coming out of the magnet unit 140 is always constant. Therefore, the frequency and sound pressure change of the sound reproduced by the speaker is adjusted to the change of the current (or voltage) value flowing through the voice coil 130.

As is well known, the damper is supported at the correct position in the magnetic gap like an edge, and smoothly moves up and down the voice coil and the diaphragm, and has a deep relationship with high power and high sound quality reproduction. In addition, the vibration plate of the speaker controls the vibration of the vibration plate (damping = attenuation) like a spring so that the speaker's diaphragm responds to the next signal normally without distortion. Therefore, in the present invention, unlike the conventional structure, since the bridge portion 131 serves as a damping function, a separate damper is unnecessary.
