Abstract: The present invention relates to a location-based service method and system using location data included in image data, particularly to a method and a system of providing the location-based service with photos taken by a camera phone, using location information at the shooting time. The location-based service method according to the present invention, using the image data provided using a terminal equipped with a camera and the location data including the location information of the terminal, comprises the steps of shooting a target image with the terminal at a predetermined location and generating first image data; receiving the location data; including the received location data in the first image data and generating second image data; and displaying an image corresponding to the first image data and providing a service using the location data, if the second image data are selected.

Abstract: A motor-noise absorbing apparatus of a vacuum cleaner is disclosed. The motor-noise absorbing apparatus includes a body seated and fixed on a peripheral part of an opening of a motor housing to close between the motor housing and a stator core and, thus, to restrict an amount of the air discharged between the motor housing and the stator core, a first air discharging part formed in the middle of the body, so that most of the air comes out of the guide vein is discharged between the stator core and a rotor, and at least one second air discharging part formed to penetrate a peripheral part of the body, so that a portion of the air coming out of the guide vein is discharged between the motor housing and the stator core.

Abstract: A vacuum cleaner is disclosed which comprises a motor chamber for mounting a motor assembly that, generates a suction force at a dust suction port, and a discharge port for guiding an air discharged from the motor chamber to the outside of a cleaner body, wherein the motor chamber comprises an air discharge opening which is in fluid communication with the discharge port; and a path extension member disposed between the motor assembly and the air discharge opening, of which edges are spaced apart from an inner wall of the motor chamber by a predetermined distance, respectively, to thereby form a detour path, and the air discharged from the motor assembly is guided in a circuitous manner by the path extension member so as to be passed through the detour path before reaching the air discharge opening. That assembly effectively reduces noise generated during operation of the motor assembly that is detectable outside of the cleaner body.

Abstract: A fan assembly for a vacuum cleaner, comprising a motor, an impeller rotatably coupled to the motor, and having a plurality of impeller wings, and a diffuser having a plurality of diffuser wings arranged along an outer circumference of the impeller. The plurality of diffuser wings includes first and second parts, the second part extending from an angle of the first part adjacent to the outer circumference of the impeller.

Abstract: Inside the main body of a vacuum cleaner is a motor casing covering the motor; on one side of the motor casing a removable filter is attached, through which air from inside the motor casing passes before being discharged inside the main body of the vacuum cleaner.

Abstract: The present invention relates to a fan assembly for a vacuum cleaner for reducing BPF noises. The fan assembly includes a motor, an impeller having a plurality of impeller blades, the impeller being rotated by the motor to suck air, and a diffuser disposed to wrap around an outer circumference of the impeller, the diffuser having a plurality of diffuser blades arranged in a predetermined interval. A ratio of an exit area of the diffuser to an entrance area of the diffuser is determined to reduce noise generated when the impeller rotates.
