Abstract: An earphone plug applicable to different system specifications includes a terminal and a switch device. The earphone plug is inserted into an earphone jack of an external electronic device for transmitting signals by a plurality of exposed signal interfaces of the terminal. The switch device combined with the terminal has a first conductor and a second conductor. When the switch device is switched between a first mode and a second mode, the first conductor and the second conductor alternately contact with two of the signal interfaces. Thus, the signal transmission defined by the signal interfaces is changed and the earphone plug is applicable to electronic devices with different system specifications.

Abstract: An earphone structure with no-section-difference design is provided, including an earphone casing, a transmission wire and a strain relief thereof. The earphone casing has a joining end to join with a joining section of the transmission wire The strain relief is formed at where the earphone casing and the transmission wire are joined. Along from the earphone casing to the transmission wire, diameter of the strain relief decreases progressively to a same diameter with that of the transmission wire, thereby providing a no-section-difference exterior look thereof between the strain relief and the transmission wire.

Abstract: A method of forming a magnetically anisotropic powder includes the steps of forming a substantially spherical powder having a major magnetic phase and an average particle size of less than about 200 microns, diffusing hydrogen into the spherical powder at elevated temperatures in an amount sufficient to disproportionate the major magnetic phase, and desorbing the hydrogen by heating the disproportionated powder under vacuum. The magnetic material from which the spherical powder is formed may be a rare earth-transition metal-boron alloy including at least one element from the iron group, at least one rare earth element, and boron. A method of forming a bonded magnet containing magnetically anisotropic particles further includes the steps of mixing the dehydrogenated powder with a binder to form a mixture, and aligning and magnetizing the powder particles in the mixture in a magnetic field.
