Abstract: A communication device and an output sidetone adjustment method thereof are disclosed. The method includes the steps of: receiving a far-end sound; receiving a near-end sound to form a sidetone and obtaining an average input volume of the near-end sound; detecting ambient noise of the near-end sound; analyzing an average noise volume and a noise frequency band of the ambient noise to determine whether the average noise volume of the ambient noise is higher than the average input volume; if yes, adjusting the volume of the sidetone in a specific frequency band by increasing it by a first gain value to form an adjusted sidetone, wherein the specific frequency band and the noise frequency band of the ambient noise belong to the same frequency band or different frequency bands; and outputting the adjusted sidetone and the far-end sound.

Abstract: A true wireless multichannel-speakers device and a multiple sound-source voicing method thereof are disclosed. The true wireless multichannel-speakers device includes a first and a second sounder. The first and the second sounders respectively include a first and a second sound effect generators, a first and a second sound effect value providers, and a first and a second speakers. The first sound effect value provider provides a first sound effect control value set to the first sound effect generator to generate a first sound effect output signal so that the first speaker outputs the first sound effect output signal. The second sound effect value provider provides a second sound effect control value set to the second sound effect generator to generate a second sound effect output signal so that the second speaker outputs the second sound effect output signal.
