20100310092 | CROSS-OVER FREQUENCY SELECTION AND OPTIMIZATION OF RESPONSE AROUND CROSS-OVER - A system and method provide at least a single stage optimization process which maximizes the flatness of the net subwoofer and satellite speaker response in and around a cross-over region. A first stage determines an optimal cross-over frequency by minimizing an objective function in a region around the cross-over frequency. Such objective function measures the variation of the magnitude response in the cross-over region. An optional second stage applies all-pass filtering to reduce incoherent addition of signals from different speakers in the cross-over region. The all-pass filters are preferably included in signal processing for the satellite speakers, and provide a frequency dependent phase adjustment to reduce incoherency between the center and left and right speakers and the subwoofer. The all-pass filters are derived using a recursive adaptive algorithm. | 2010-12-09 |

20100310094 | DISPLAY DEVICE AND DRIVING METHOD THEREOF - A display device and a method of driving the display, wherein the volume of background music is controlled depending upon the color or brightness of display images, and the power consumption is reduced. The display device includes a display unit with a plurality of pixels, a signal controller, and a volume controller. The display unit displays images by selectively activating pixels from among the plurality of pixels in accordance with input video signals and input image control signals. The signal controller reads the input video signals to generate on-pixel signals having information about the ratio of a number of the active pixels compared to a total number of pixels in the plurality of pixels per each frame. The volume controller determines a range from among predetermined ratio ranges corresponding to the ratio of the number of active pixels to define a plurality of volume levels, and determine the volume level corresponding to the on-pixel signal to control the volume according to the ratio corresponding to the determined volume level. | 2010-12-09 |
20100310095 | Method for Providing a Mute Control Function for Multiple Microphones Connected to a Computer - A method for providing a mute control function in a computer having multiple microphones is disclosed. A set of mute state information is stored in a control table of a portable computer. The mute state information is for controlling a mute state. Device identifiers (IDs) of all microphones that are connected to the portable computer are registered with the control table. The microphones corresponding to the device IDs registered in the control table are controlled to be in the same mute state based on the mute state information. In response to a detection of an activation of the mute button, the mute state information are inverted. The device IDs registered in the control table are to be controlled in the same mute state based on the inverted mute state information. | 2010-12-09 |
20100310096 | Switchable Attenuation Circuit for MEMS Microphone Systems - A switch control circuit monitors a signal produced by a MEMS or other capacitor microphone. When a criterion is met, for example when the amplitude of the monitored signal exceeds a threshold or the monitored signal has been clipped or analysis of the monitored signal indicates clipping is imminent or likely, the switch control circuit operates one or more switches so as to selectively connect one or more capacitors to a signal line from the microphone, i.e., so as to connect a selected capacitance to the signal line to attenuate the signal from the microphone and, therefore, avoid clipping. The switches may be MOSFET, MEMS or other types of switches co-located with the microphone in a common semiconductor package. Similarly, the capacitors, a circuit that processes the signals from the microphone and/or the switch control circuit may be co-located with the microphone in a common semiconductor package. | 2010-12-09 |
20100310097 | APPARATUS AND METHOD FOR OUTPUTING AUDIO SIGNAL IN PORTABLE TERMINAL - An apparatus and a method for outputting an audio signal in a portable terminal are provided. The portable terminal for outputting an audio signal includes an ear jack, a modem, and an amplifier. The ear jack connects the portable terminal with one of an earphone and an external apparatus. The modem detects whether one of the earphone and the external apparatus is connected to the ear jack. When connection of the external apparatus is detected, the amplifier high power-amplifies the audio signal and outputs the same to the external apparatus according to a control of the modem. | 2010-12-09 |
20100310098 | ELECTRET TRANSDUCER WITH SOLAR POWER - The present invention provides an electret transducer with solar power. The provided electrets transducer includes a solar power supply device, an amplifier circuit having a first input terminal coupled to the solar power supply device and a second input terminal coupled to an audio signal input terminal, and an electret loudspeaker coupled to an output terminal of the amplifier circuit. The amplifier circuit receives a first voltage level via the first input terminal and boosts the first voltage level to a second voltage level, and receives a first audio signal via the second input terminal and amplifies the first audio signal to a second audio signal. The electret loudspeaker coupled to the output terminal of the amplifier circuit receives the second audio signal and outputs a sound corresponding to the second audio signal. | 2010-12-09 |
