摘要： The present invention discloses a sound converter with an enclosure which utilizes an outer space to expand a resonance space. The sound converter with the enclosure includes a frame being equipped with a magnetic circuit for forming a magnetic field in a predetermined gap, a voice coil at least partially positioned in the gap, a diaphragm adhered to the voice coil and inserted into a diaphragm seating portion of the frame, a protector formed at the upper portion of the diaphragm, and an enclosure case coupled to the frame, for defining the inner space of the enclosure which is the resonance space. A vent is provided at the enclosure case so that the inner space of the enclosure can communicate with the outer space. This configuration can secure a wide resonance space.

摘要： Disclosed is a pole-change type motor that provides a variable-speed (two-pole or four-pole type) operation system capable of reducing the load of the motor of the normal operation system and improving the cooling efficiency. In case of a quick operation, the motor switches over to the two-pole type according to the control of a relay section. At this time, the load of the motor is reduced by offsetting an abnormal magnetic field distribution formed due to the same polarity of adjacent main windings using compensation windings of an opposite polarity. If the quick operation is needed, the motor switches over to the two-pole type, and operates at a high speed to achieve the quick cooling. Then, if a standard operation is possible with the lapse of the predetermined time, the motor switches over to the four-pole type, and operates at a low speed to achieve an effective cooling.
