Abstract: The present disclosure relates to a composition for preventing, ameliorating or treating sleep disorder or insomnia, which contains an extract of a roasted citrus byproduct as an active ingredient. The extract of a roasted citrus byproduct of the present disclosure has very excellent effect of decreasing sleep latency, increasing sleep duration and increasing non-REM sleep. In addition, the composition of the present disclosure, which contains ingredients derived from the naturally occurring citrus byproduct, can ensure safety without inducing the side effects of synthetic drugs including pentobarbital and benzodiazepine and with no side effects such as cognitive impairment, tolerance or dependency even after long-term use. Accordingly, the composition for preventing, alleviating or treating sleep disorder, which contains an extract of a roasted citrus byproduct as an active ingredient, of the present disclosure is very useful for preparation of a food composition and a pharmaceutical composition.

Abstract: Discussed is a cradle for a wireless audio device. The cradle can include a casing including a seating groove for seating the wireless audio device, wherein the casing is able to be opened and closed, a transceiver disposed in the casing, a switch formed in a part of the casing, and an external device interface including an input terminal formed in another part of the casing, wherein in response to a first cable being connected to the input terminal in a wired connection mode, one of the transceiver and the external device interface performs a bi-directional wireless audio transmission for audio signal exchange with the wireless audio device, and wherein in response to a second cable being connected to the input terminal in the wired connection mode, one of the transceiver and the external device interface performs a unidirectional wireless audio transmission for audio transmission to the wireless audio device.

Abstract: A portable sound apparatus including a body wearable on a user's body, an ear bud holder formed on the body, the ear bud holder being closed on one side and having an opening on an opposite side, an ear bud having one side inserted into the ear bud holder and an opposite side exposed through the opening of the ear bud holder, and a first magnet positioned in the ear bud holder is provided. The ear bud includes an ear bud housing having a sound hole on one side, an ear tip coupled to the sound hole and positioned within the ear bud holder when the ear bud is coupled to the ear bud holder, a receiver positioned inside the ear bud housing and configured to output sound through the sound hole, and a second magnet having an opposite polarity to the first magnet.
