Abstract: A transceiver includes a transmission module for generating an output signal, a controller for controlling the transmission module to allow an output signal to have one of a first frequency and a second frequency, a reception module for controlling the controller to allow a control signal to be outputted based on completion information received from the outside. The transmission module outputs an output signal having a first frequency to perform human body communication. When the reception module receives completion information, the transmission module outputs an output signal having a second frequency in response to the control signal in order to perform wireless communication. The first frequency is lower than the second frequency.

Abstract: A hearing-aid apparatus using ultrasonic waves is inserted and mounted within an external auditory meatus of an ear, generates an ultrasonic wave band signal by single side band amplitude modulation of a sound signal that is received through a microphone, and outputs the ultrasonic wave band signal and a carrier signal that is used for single side band amplitude modulation as an ultrasonic wave signal to a transfer medium in a predetermined beam direction. Therefore, the ultrasonic wave signal forms a focal area in a damaged hearing organ area, the ultrasonic wave band signal is restored to a sound signal by nonlinear characteristics of a transfer medium in the focal area, and the damaged hearing organ detects the sound signal.

Abstract: Provided are a method and apparatus for transmitting sound waves in water. The method for transmitting sound waves in water includes generating a sound wave signal, and transmitting the sound wave signal in water, generating a compensation signal for preventing distortion due to water vibration in an audible frequency band, and simultaneously transmitting the compensation signal and the sound wave signal in water. Accordingly, an apparatus for receiving sound signals is not required, and direct contact between a human body and an apparatus for transmitting sound signals is not required, thereby improving convenience of use. In addition, even when a human body is constantly moving, a superior contact condition may be provided, and therefore sound waves may be more effectively transmitted to a user.
