发明名称 SPEAKER DEVICE
摘要 A speaker device for reproducing an audio signal includes a first speaker including a first diaphragm and a first magnetic circuit that drives the first diaphragm, where the first diaphragm reproduces an audio signal including a predetermined frequency range, a second speaker including a second diaphragm and a second magnetic circuit that drives the second diaphragm, where the second diaphragm reproduces an audio signal including a frequency range substantially the same as the predetermined frequency range, and at least one cabinet having the first speaker and the second speaker mounted therein so that radiation directions of sounds are opposite to each other. At least part of a space formed between the first speaker and the second speaker communicates with the outside of the cabinet. When the speaker device reproduces the audio signal, the first diaphragm and the second diaphragm vibrate in opposite directions.
