    Abstract: In a speaker, three magnets are arranged with a magnetic gap between them and a voice coil is placed in the magnetic gap. Magnetic poles of magnets on opposite sides of magnetic gap are magnetized so that the same poles of the magnets face each other. Both poles of the magnet at the center are arranged in the direction perpendicular to the direction connecting both poles of each of the magnets on opposite sides. A hole is formed in a diaphragm, at a position facing the magnet located at the center. Magnetic fluid is placed between a side face, which faces the magnetic gap, of the center magnet and the voice coil.

    Abstract: A speaker comprises a diaphragm, a voice coil secured to the diaphragm, a first magnet having a first magnetic pole face facing the voice coil, a second magnet arranged inside the voice coil, and a magnetic fluid provided between the first magnet and the voice coil. The first magnet has a first magnetic pole face facing the voice coil toward the inside thereof. The second magnet has a second magnetic pole face arranged inside the voice coil such that the flux passing the first magnetic pole face of the first magnet intersects the voice coil in the direction perpendicular to the voice coil and the vibrating direction. The magnetic fluid isin contact with the first magnetic pole face and the voice coil. This speaker is thin but produces a large voice output while preventing rolling phenomenon.

    Abstract: A voice coil wound up in loop shape having the inside is secured to a vibration cone which vibrates in the vibrating direction. A first magnet having a first magnetic pole face is attached to an upper case, and a second magnet having a second magnetic pole face is attached to a lower case. After the first magnet is attached to the upper case, magnetic fluid is made to adhere to the first magnetic pole face of the first magnet. After the voice coil is secured to the vibration cone and the magnetic fluid is made to adhere to the first magnetic pole face of the first magnet, the vibration cone is attached to the upper case such that the first magnetic pole face of the first magnet opposes the voice coil toward the inside thereof, and the magnetic fluid is provided between the first magnetic pole face of the first magnet and the voice coil to abut against the first magnetic pole face and the voice coil. After the second magnet is attached to the lower case and the vibration cone is attached to the upper case, the lower case is attached to the upper case such that the flux passing the first magnetic pole face of the first magnet intersects the voice coil in the direction perpendicular to the voice coil and the vibrating direction, and the second magnetic pole face is arranged on the inside of the voice coil. With such a method, a thin speaker producing a large voice output while preventing rolling phenomenon is obtained.
