| 20090161905 | SPEAKER AND MAGNETIC CIRCUIT - A high performance speaker is provided and includes a simple structure magnetic circuit achieved without the need of a complicated manufacturing process, and a high performance speaker is provided and includes a simple structure diaphragm achieved without the need of a difficult process for forming a U shape of a narrow width in the diaphragm. A speaker | 06-25-2009 |
| 20110051988 | SPEAKER DEVICE - A speaker device includes a pair of diaphragms disposed opposite each other, a frame configured to vibratably support an outer periphery of the diaphragms in the vibration direction, and a plurality of driving parts configured to support a rear surface of each of the diaphragms and vibrate the diaphragms in response to an audio signal. The driving parts include a pair of magnetic circuits in which a magnetic gap is formed in a direction different from the vibration direction of the diaphragms, a pair of voice coils vibratably arranged in the magnetic gap in one axis direction, vibrating so as to move toward or away from each other in response to the audio signal, and a rigid vibration direction converter part configured to convert the direction of the vibration of the voice coils and transmit the vibration to the diaphragms. | 03-03-2011 |
