摘要： A speaker device includes a housing that has a sound guide space having a vertically flattened shape, a first speaker disposed in the housing to be oriented toward a front of the housing, and a second speaker that is disposed in the housing and is oriented upward or downward to output sound into the sound guide space positioned at an internal upper part or an internal lower part of the housing. The sound guide space opens at an opening that is formed in vertically flattened form in the housing, and the opening has a vertical height that is smaller than an aperture of the first speaker.

摘要： A speaker system includes a wearable speaker capable of outputting a first sound which is a voice of a communication partner of a talker and a second sound, a microphone, and a sound processing device which processes a sound output from the wearable speaker and a sound picked up by the microphone. The sound processing device generates a reference signal by synthesizing a first signal indicating the first sound and a second signal indicating the second sound, outputs the first signal and the second signal to the wearable speaker, obtains a sound pickup signal including the voice of the talker from the microphone, performs, on the sound pickup signal, a process of cancelling the sound component output from the wearable speaker by using the reference signal, and outputs the sound pickup signal on which the cancellation process has been performed.
