20140307912 | FULL-AUDIO-RANGE SPEAKER - A full-audio-range speaker has a box, at least one dynamic speaker unit, and a vibration speaker. The box has multiple side walls and at least one wall hole. The at least one dynamic speaker unit is mounted in the box and has a sound hole aligned with the at least one wall hole. The vibration speaker is mounted through the box. The at least one dynamic speaker unit and the vibration speaker respectively improve midrange, treble, and bass performances of the full-audio-range speaker. Therefore, the full-audio-range speaker can have relatively good midrange, treble, and bass performances simultaneously. | 10-16-2014 |
