Abstract: A voice enhancing device with an audio focusing function is disclosed. The voice enhancing device has an audio focusing function capable of selectively enhancing voice depending on a speaking person's location. The voice enhancing device, which is wearable on a human body, includes: left and right earphones configured to fit into left and right ears of a wearer of the voice enhancing device, respectively; two or more microphones configured to acquire a sound; and a processing part configured to at least perform signal processing tasks for active noise cancellation on sound signals from the microphones and output processed sound signals to the earphones. The processing part is configured to perform the signal processing tasks to amplify only sound signals picked up from an interested direction and to attenuate sound signals picked up from other directions.

Abstract: A headset device with active noise reduction includes a housing configured to be mounted near or in a human ear, a speaker unit equipped within the housing and configured to emit a sound signal, one or more microphone units configured to collect ambient sound and a signal processor electrically connected to the one or more microphone units. The signal processor is configured to selectively operate either in a hearing aid mode in which ambient sound coming in from the outside through the one or more microphone units is emitted, or in a noise reduction mode in which ambient sound coming in from the outside is inverted and the inverted ambient sound is emitted through the speaker unit to reduce the ambient sound. A corresponding method of operating the headset device is also provided.
