Abstract
A speaker device employing a diaphragm structure for providing high quality sound characteristics. In particular, a separate speaker unit is additionally provided so as to improve a resonator characteristic produced at the rear side of an existing speaker. As such, the rear sound arriving at an end of the resonator is dampened by the sound outputted from the additional speaker unit, thereby improving characteristics, such as clearness, total harmonic distortion, etc.

3. A speaker device for outputting a sound, comprising:
-
an amplifier outputting a first audio signal; a first speaker unit connected to an output terminal of the amplifier, the first speaker unit outputting a first sound from the first audio signal ; and a second speaker unit connected to an input terminal of the amplifier, wherein, when a second input audio signal identical to a first input audio signal inputted to the amplifier is inputted to the second speaker unit, the second speaker unit outputs a second sound to dampen a rear sound outputted from a rear side of the first speaker unit, wherein the speaker device has an internal space divided by at least one diaphragm into a sound passage and a mounting space for mounting the first speaker unit, the second speaker unit being placed at a distal end portion of the sound passage with reference to the mounting space. - View Dependent Claims (4, 5, 6, 7)
