A mobile terminal includes a first case having a groove recessed along one region, a second case coupled to the first case to cover the one region, and a sealing member filled in the groove, the sealing member closely adhered onto the second case to seal the one region, wherein a volumetric center of the sealing member is located more adjacent to a surface of the sealing member than to an inner side of the sealing member, such that the surface of the sealing member is formed earlier than the inner side of the sealing member to prevent or reduce formation of a weld line on the surface of the sealing member.

Mobile terminal with sealing structure

A portable terminal comprise a lower body, an upper body disposed to overlap the lower body, and formed to be in an open configuration which exposes a part of an upper surface of the lower body, and a closed configuration which covers the one part by a sliding motion, a flexible printed circuit board (FPCB) having one end connected to the lower body and another end connected to the upper body, and formed to be bent as the upper body moves with respect to the lower body, and an FPCB retention unit configured to elastically move one or more bent portions of the FPCB into an accommodation space formed in the upper body when the upper body moves from a closed configuration to an open configuration.

Portable terminal

Disclosed herein is a signal processing apparatus and method for removing a reflected wave generated by a robot platform. The signal processing apparatus includes a transfer function measuring unit for measuring an inter-channel transfer function (IcTF) from signals of a plurality of channels; an impulse response obtaining unit for obtaining an inter-channel impulse response (IcIR) from the IcTF measured by the transfer function measuring unit; and reflected wave removing unit for removing the reflected wave by differentiating a direct wave directly generated by a sound source and the reflected wave with a time delay from the IcIR obtained by the impulse response obtaining unit. The signal processing method of removing a reflected wave includes measuring an IcTF from signals of a plurality of channels; obtaining an IcIR from the measured IcTF; and removing the reflected wave by differentiating a direct wave directly generated by a sound source and a the reflected wave with a time delay from the obtained IcIR.

Disclosed herein are an artificial ear and a method for detecting the direction of a sound source using the same. The artificial ear includes a plurality of microphones; and one or more structures disposed between the plurality of microphones. In the artificial ear, the amplitudes of output signals respectively inputted to the plurality of microphones are designed to be different based on the direction of a sound source. The method for detecting the direction of a sound source includes receiving output signals with different amplitudes from a plurality of microphones; determining front-back discrimination of the sound source from a difference between the amplitudes of the output signals of the microphones; and determining an angle corresponding to the position of the sound source from a difference between delay times of the output signals of the microphones.
