The present invention relates to a sound transducer and, more specifically, to a sound transducer which is driven using a solenoid type, not the driving principle of a dynamic type using a voice coil. The present invention provides the sound transducer comprising: at least one magnet or solenoid which generates a magnetic field; a lower yoke to which the magnet or the solenoid is attached, and which forms a magnetic path; an upper yoke to which the magnet or the solenoid is attached, and which forms a magnetic path; a magnetic flux forming device which is positioned on magnetic flux formed by a magnetic field circuit and forms magnetic flux according to an electrical signal; a vibrating plate which is attached to the magnetic flux forming device to vibrate depending on the movement of the magnetic flux forming device; and a frame to which the lower yoke is fixed. The magnet, the solenoid, or nothing is attached to the lower yoke and the upper yoke, respectively. That is, possible is an embodiment in which the magnet or the solenoid is attached to only the lower yoke and nothing is attached to the upper yoke, and vice versa. |
