摘要： Several embodiments of the instant invention incorporate a loudspeaker design utilizing hard magnetic poles and yokes. The magnetic field of the loudspeaker is created and guided with a series of critically formed hard magnetic structures guiding the magnetic field from the primary magnet to the gap in a loop of hard magnetic material, replacing the soft magnetic materials normally used. Magnetization of the components of the hard magnetic loudspeaker driver with radial pole patterns—a yoke radial magnet, a washer pole magnet and a yoke upper ring magnet—is performed with these components in their final assembly relationships.

摘要： There is provided an electromagnetic actuator which can secure a sufficient thrust force at least at a certain level over a wide range of displacement. The electromagnetic actuator 1 having a point of amplified displacement includes: a displacement amplification mechanism 1A made of a magnetic material and having two surfaces 2as, 2bs that form a gap 5 therebetween; and a coil 6 provided in the displacement amplification mechanism 1A. A magnetic flux is generated by passing an electric current through the coil 6, thereby generating an attraction force between the surfaces 2as, 2bs. The attraction force displaces the point of amplified displacement.

摘要： A speaker collective substrate with component insertion hole sections and electrode sections has a plurality of speaker forming areas. An electrical speaker section, which comprises a magnetic circuit section and a vibration section, is inserted into each of the component insertion hole sections. Then, a collective lid, in which a plurality of lids have been formed for sealing the electrical speaker sections, is attached onto the speaker collective substrate. After that, the speaker collective substrate and the collective lid are divided into individual speaker forming areas along partition lines extending in the directions of the X and Y axes to form individual dynamic speakers. Thus, it is possible to mass-produce dynamic speakers with uniform quality through a collectively manufacturing process.

摘要： An ultrasonic emitter device having broad frequency range capacity with relatively large diaphragm displacement compared to typical electrostatic diaphragm movement. The device includes a core member able to establish a variable magnetic field adjacent the core member. A movable diaphragm is stretched along and displaced a short separation distance from the core member to allow an intended range of orthogonal displacement of the diaphragm within a strong portion of the magnetic field. At least one conductive ring disposed on the movable diaphragm within the influence of the variable magnetic field of the core member for enabling current flow through the ring for developing a second magnetic field which interacts with the first magnetic field to repel and relax the diaphragm at a desired frequency for development of a series of compression waves which may be adjusted to include an ultrasonic frequency range.
