发明名称 Sound reproducing device and sound reproduction method for echo cancelling and noise reduction
摘要 A sound reproducing device is provided including a communication unit that transmits/receives signals; at least one sound output unit that outputs sound based upon a signal having been received, a sound pickup unit that picks up sound and generates audio data, an echo canceller unit that stores any echo signal contained in the signal having been received at the communication unit and generates a dummy echo signal by using the stored echo signal, and a noise reducing unit that generates a cancel signal to be used to cancel noise by using the audio data if the sound picked up at the sound pickup unit contains noise originating from a noise source and outputs a composite signal generated by combining the output signal from the echo canceller unit and the cancel signal.
