摘要： A wearable acoustic transducer includes a communication part for performing communication and speaker and control modules. The speaker module includes an enclosure having an inner space, a first opening in which a speaker part is mounted being formed in a first side surface thereof, a second opening in which a passive vibration part is mounted being formed in a second side surface thereof, the speaker part configured to emit sound, and a passive vibration part for relieving air stiffness in the inner space of the enclosure. The control module performs gain correction on an electric signal including sound or voice that is received from the communication part according to prestored gain correction data and applies the gain-corrected electric signal to the speaker part, or generates an electric signal corresponding to the gain correction data and applies the electric signal to the speaker part.

摘要： 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.
