Abstract:
Provided is an earset. The earset includes an internal microphone provided inside an earphone worn on a user's ear, and configured to receive a first sound transferred from the user's mouth through an external auditory meatus via an Eustachian tube and convert the first sound into a first sound signal, at least one external microphone provided outside the earphone, and configured to receive a second sound provided from the user's mouth and convert the second sound into a second sound signal, and a controller configured to filter a noise of the second sound signal based on the first sound signal, remove the noise, and generate a third sound signal.
Abstract:
Disclosed is an ear microphone which includes: a microphone for converting a voice signal provided from the external auditory meatus of a user to an electric signal; a speaker for converting the electric signal provided from an external device to the voice signal; and a soundproof member having a microphone receiving groove for fixing and supporting the microphone to the inside of the housing and a speaker receiving groove for fixing and supporting the speaker to the inside of the housing.
Abstract:
Disclosed is a voltage control device including a voltage detector detecting an output voltage output from an output port of a mobile communication device; and a voltage control circuit bypassing the output voltage to an earpiece in which a speaker and a microphone are integrally formed when the output voltage detected by the voltage detector is between a first voltage and a second voltage higher than the first voltage.

Abstract:
Each of a mobile communication terminal (100) and a headset (200) in the present invention measures the distance to another wirelessly connected device and determines whether the other device is lost. According to the present invention, the mobile communication terminal (100) in a headset system having a loss prevention function comprises: a first communication module (110) for forming a communication channel with the headset (200); a first breakaway analyzing unit (120) analyzes whether the headset (200) breaks away at a standard distance loss from a location of the mobile communication terminal (100) by analyzing a sensitivity signal delivered via the first communication module (110); and a first breakaway warning unit (140) for warning a user of a breakaway by using at least one of a vibration signal, a sound signal, or an image signal when analysis reveals that the headset (200) has broken away at the standard distance loss from the first breakaway analyzing unit (120). The headset (200) having a mobile communication terminal (100) loss prevention function according to the present invention comprises: a second communication module (210) for forming a communication channel with the mobile communication terminal (100); the second breakaway analyzing unit (220) for analyzing whether the mobile communication terminal (100) breaks away at the standard loss distance from the location of the headset (200) by analyzing a sensitivity signal delivered via the second communication module (210); and a second breakaway warning unit (240) for warning the user of a breakaway when analysis reveals that the mobile communication terminal (100) has broken away from the standard loss distance.
Abstract:
Disclosed is an earset. The earset includes a case that forms an appearance thereof, an ear pad that is mounted in one end portion of the case and is attached to/detached from a user's ear, and a soundproof housing that is accommodated in the case and in which a speaker and a microphone are arranged in a forward/backward direction along an axial line of the ear pad.

Disclosed is an earset. The earset includes: a case that forms an appearance thereof; an ear pad that is mounted in an end portion of the case, forms a communication hole communicating with a user's external auditory canal, and is attached to/detached from a user's ears; and a soundproof housing that is received in the case, and includes a speaker output hole for transmitting sound generated from a speaker to the communication hole of the ear pad, a microphone input hole for transmitting the sound transmitted from the user's ears to the communication hole of the ear pad to a microphone, a speaker accommodating groove for accommodating the speaker while communicating with the speaker output hole, a microphone accommodating groove for accommodating the microphone while communicating with the microphone input hole, and one or more back holes for allowing a part of sound flowing into the microphone input hole to flow into a rear surface of the microphone accommodated in the microphone accommodating groove while communicating with the microphone input hole.
Abstract:
Disclosed are an earset that may correct a frequency band of a voice coming from a user's ears into a frequency band of a voice coming from the user's mouth, and a control method for the same.According to an embodiment, the control method for the earset including a first earphone unit that is inserted into ears of a user while including a first microphone and a first speaker, and a main body in which a second microphone is disposed, the control method includes: determining whether a voice correction function is activated; and correcting a frequency band of a voice input to the first microphone into a frequency band of a voice input to the second microphone, when the voice correction function is activated.
