  • DIGITAL AUDIO AMPLIFICATION DEVICE USING HARMONICS AND METHOD THEREOF
    Publication number: 20140023208
    Abstract: The present invention relates to a digital audio amplification device using harmonics and a method thereof, and more specifically, the invention differentially generates characteristics of harmonics (for instance, amplitude or frequency components of harmonics) of an audio signal in order to compensate the audio signal that exceeds a preset threshold value according to the amplitude and characteristics of the audio signal, if the audio signal exceeds the preset threshold value, thereby easily improving the amplitude and the pitch of audio during digital audio amplification.

  • Magnetic core for inductor
    Patent number: 6897754
    Abstract: Disclosed is a low-priced and small-sized magnetic core for an inductor suitable for a high frequency signal and a large-current signal. The magnetic core is modified from a conventional EP type magnetic core. A recess is integrally formed with a peripheral portion of the magnetic core when it is shaped. A bottom portion and the peripheral portion are extended toward an opening portion to an extent of about 70 percentages of a length measured from a center of the center portion to an internal surface of the peripheral portion. The peripheral portion opposite to the opening portion has a uniform thickness. The magnetic core is designed to facilitate its surface mounting onto a PCB.
