Abstract: A light-emitting element comprises a first semiconductor layer, an active layer provided on the first semiconductor layer, a second semiconductor layer provided on the active layer, an electrode layer provided on the second semiconductor layer, and an insulating film around outer peripheral surfaces of the first semiconductor layer, the active layer, the second semiconductor layer, and the electrode layer, wherein the active layer includes a cover layer including a plurality of quantum dots, and the first semiconductor layer, the active layer, the second semiconductor layer, and the electrode layer are sequentially stacked in one direction to form a shape of a rod.

Abstract: A mobile apparatus and control method thereof are provided, which includes an audio data signal input unit arranged to receive an audio data signal. An audio output unit is arranged to output an audio signal according to the received audio data signal within a first reproduction frequency. A balanced armature is arranged to output an audio signal according to the received audio data signal within a second reproduction frequency band. The second reproduction frequency band is different from the first reproduction frequency band. An audio signal processor is arranged to adjust the first reproduction frequency band and the second reproduction frequency band such that a combination of the first reproduction frequency band and the second reproduction frequency band is wider than the first reproduction frequency band and the second reproduction frequency band individually.

Abstract: An apparatus and method for outputting audio signals of a portable communication device are provided. The apparatus includes a plurality of audio tables including different volume control values or tone control values, and allows a user to selectively set audio tables corresponding to each of audio paths equipped with the portable communication device. Further, the apparatus analyzes a surrounding environment during a voice call, determines the absence or presence of noise, and suitably controls a volume or a tone of audio signals based on the result of the determination before outputting the audio signals. Accordingly, the apparatus can provide an improved calling condition in various calling environments.

Abstract: An electronic device is provided. The electronic device includes a reception unit configured to receive an audio signal, a bandwidth change unit configured to gradually change a bandwidth of the received audio signal from a first bandwidth to a second bandwidth during a preset time, when the received audio signal is changed, and an audio output unit configured to output the received audio signal.
