Abstract: A mobile terminal having an integrated radio function according to an embodiment of the present disclosure includes an antenna configured to receive a digital radio signal, a radio connection module configured to support connection and communication with an analog radio, a display configured to play at least one of an audio signal, an image signal, and additional information, and a radio application configured to restore the audio signal, the image signal, and the additional information by decoding the digital radio signal and then play the audio signal, the image signal, and the additional information through the display, and transmit the audio signal to the analog radio when the analog radio is connected.

Abstract: A hearing aid using a printed circuit board (PCB) is provided, which minimizes internal wires since components of the hearing aid are disposed on the PCB. In the hearing aid using a PCB, hearing aid components can be automatically disposed and soldered on the PCB, and through this the total process time, including manufacturing time, can be substantially reduced.

Abstract: A digital hearing aid enhancing a directional performance for a patient who suffers from sole-ear hearing impairments is provided, in which the digital hearing aid cell inserted into one healthy ear is electrically connected with another digital hearing aid cell called an ear cell including a microphone worn in the other troubled ear, via an external electric wire. Two digital hearing aid cells are connected with each other via signal, power, and ground wires to thereby adjust a time delay parameter and thus make a time delay effect between the two microphones, so that a wearer who wears the digital hearing aid can better hear sound which comes from the side opposing the healthy ear, that is, from the troubled ear side.
