    摘要: The present invention is directed to a method for producing induced electricity which prevents a collision by guiding induced electromagnetic force generated from a power generation coil as electricity is produced in the power generation coil to a predetermined location deviating from the path of power generation magnetic force which proceeds to be interlinked with the power generation coil to thus prevent power generation resistance from occurring and also produces electricity by interlinking the induced electromagnetic force with the power generation coil. The present invention is also directed to a “method for producing electricity using the induced electromagnetic force of a power generation coil” which uses an energy source for the production of electricity without conversion, so that there are no loss of energy during an energy conversion process and maintenance and management are easy, thereby reducing costs.

    摘要: The present invention relates to an earphone equipped with a pressure equalizing means, and more specifically to an earphone equipped with a pressure equalizing means, in which a speaker unit is disposed inside an earphone housing in a longitudinal direction and a first air path is formed to discharge sound waves, generated by the diaphragm of the speaker unit, to the external ear canal through one side of the speaker unit. When air inside the external ear canal is discharged out of the speaker unit, air is discharged into the vibration space of the speaker unit by using the first air path, and is then discharged out of the speaker unit through a second air path formed in the other side of the top surface of the speaker unit.

    摘要: A rectangular microspeaker according to the present invention transfers vibration sound through the front surface or side surface of a diaphragm. In order to maximize an effective vibration area and to expand a volume, all parts including a frame are fabricated in a rectangular shape. The present invention is applied to a P type, an F type, and a composite type. The vibration sound generated on the bottom of the diaphragm as well as the vibration sound generated on the top of the diaphragm may be discharged through the side surface. A magnetic field part may be insert-molded separately or along with the frame.
