Provided is a device for outputting an audio signal. The device includes: a vibrator configured to output the audio signal; a vibrator cover provided on the vibrator to transmit the output audio signal to a surface of an object mounted with the device; a sensor configured to measure a pressure between the surface of the object and the vibrator cover; a distance adjusting unit configured to adjust a distance between the surface of the object and the vibrator cover based on the pressure measured by the sensor to optimally output the audio signal; and a control unit configured to control the vibrator, the sensor, and the distance adjusting unit.

Device for outputting audio signal and method for outputting audio signal

A wearable device communicating with an external device by using a vibration signal applied to a body part of a user wearing the wearable device, and a method of operating the wearable device are provided.

Wearable device and method of operating the same

An apparatus for processing a speech signal is provided. The apparatus includes a communicator comprising communication circuitry configured to transmit and receive data, an actuator comprising actuation circuitry configured to generate vibration and to output a signal, a formant enhancement filter configured to increase a formant of the speech signal, and a controller comprising processing circuitry configured to control the speech signal to be received through the communicator, to estimate at least one formant frequency from the speech signal based on linear predictive coding (LPC), to estimate a bandwidth of the at least one formant frequency, to determine whether the speech signal is a voiced sound or a voiceless sound, to configure the formant enhancement filter based on the at least one formant frequency, the bandwidth of the at least one formant frequency, characteristics of the determined voiced sound or voiceless sound, and signal delivery characteristics of a human body, to apply the formant enhancement filter to the speech signal, and to control the speech signal to which the formant enhancement filter is applied to be output using the actuator through the human body.
