Abstract: Disclosed is a method for controlling volume of a true wireless stereo bluetooth earphone including a pair of left and right touch switches, the method including recognizing a user's touch during media playback or a phone call; determining whether the touch is a shorter touch or a longer touch than a configuration time; increasing the volume by one increment while entering a volume-up mode when the touch is a short touch, according to the determining; determining whether there is an additional short touch within the configuration time; returning to the increasing of the volume by one increment each time there is an additional short touch, according to the determining; returning to checking whether a first volume control mode is entered by existing the volume-up mode when there is no touch for the configuration time; and several additional determining.

Abstract: A bone conduction-using headset: a pair of main bodies (200), a pair of unit bodies (220); a pair of suspenders (210), each of the suspenders having a shape of letter “U”; and a connector (240) connected to the main bodies (200) wherein: each of the main bodies extends downward at a rear side R of the ear E of the user P, has a length longer in a longitudinal direction thereof than in a transverse direction thereof; the connector (240) is connected to and extends from ends of the main bodies (200) toward a rear side of a neck N of the user P at a wearing inclination angle a with respect to a longitudinal axis C of the main body (200); and an inner circumference part R of the connector (240) is located around the rear side of the neck N of the user P.

Abstract: Disclosed is a method of operating a screen on a touch screen S of a portable terminal H, wherein a touch point is moved on a touch screen S of a portable terminal H from one point of a main touch area M which is a central work area of the touch screen S toward corner areas A1, A2, A3, A4 of the touch screen S by a finger F of a user or a touch pen while touch sensing is maintained such that a screen is enlarged, an enlargement ratio of the screen is increased by moving the touch point to the main touch area M and repeatedly moving the touch point to the corner areas A1, A2, A3, A4, a touch point is moved from one point of the corner areas on the touch screen S toward the main touch area M such that the screen is downscaled.

Abstract: A mounting type Bluetooth unit is provided, which can lengthen the life span of a battery. The mounting type Bluetooth unit is fixedly installed in the interior of a vehicle and is provided with a casing body that packages a circuit board having a controller with control logic for performing Bluetooth communication with a Bluetooth device of a portable phone. The controller further includes a human body sensor as a control switch of operation logic. Also, the controller further includes a logic for sensing a driver's getting into/out of the vehicle in accordance with existence/nonexistence of a sensing signal of the human body sensor and controlling the operation of the Bluetooth unit in a sleep/awake or power-on/off state to cancel pairing with the Bluetooth device in a non-use state.
