The control unit is further configured to receive the acoustic leakage position signal and to adapt the electrical input signal responsive to the acoustic leakage position signal. | 2013-10-10 |
20130266149 | COMMUNICATION SYSTEM AND METHOD HAVING ECHO-CANCELLING MECHANISM - A communication system having echo-cancelling mechanism is provided. The communication system communicates with a remote communication device. The communication system comprises a computer system end, a digital playback device, a sound-receiving module, a digital-to-analog (D/A) converter and a digital processing module. The computer system end receives a digital signal from the remote communication device. The digital playback device plays the digital signal to generate a sound signal. The sound-receiving module generates an analog audio signal comprising the sound signal. The D/A converter receives a digital sound signal of the digital signal and converts the digital sound signal to an analog sound signal. The digital processing module performs an echo-cancelling process on the analog audio signal according to the analog sound signal. | 2013-10-10 |
20130266150 | ACTIVE NOISE CANCELLING EAR PHONE SYSTEM - An earphone has a casing, containing a speaker, the casing being adapted to fit within the outer ear of a user at the entrance to the ear canal of the user. The casing has a guide, protruding from the front surface of the casing, and suitable for locating in the ear canal of the user. The casing is also adapted to allow sound to pass through a sound-permeable portion of the front surface. The casing has sound channels, leading across the front surface of the casing from the sound-permeable portion to a periphery of the first surface of the casing. The earphone can be used in a noise cancelling earphone system, with signal processing circuitry connected to the microphone and to the speaker, wherein the signal processing circuitry is adapted to receive the ambient noise signal from the microphone, and to apply the ambient noise signal to a filter having a controllable amount of gain, for generating a noise cancellation signal for transmission to the speaker. The result is that, however the earphone is worn within the outer ear of a user, an amount of sound leakage lies within a predetermined range, such that the amount of gain to be applied by the signal processing circuitry falls within a relatively narrow range. | 2013-10-10 |

20130266152 | SYNCHRONIZING WIRELESS EARPHONES - Various embodiments are directed to systems and methods involving first and second acoustic speaker devices for synchronizing playback of a common audio playback signal by the first and second acoustic speaker devices. The first acoustic speaker device may transmit wirelessly a first message comprising a first checksum set comprising a plurality of checksums indicating units of the common audio playback signal in a playback queue of the first acoustic speaker device. The second acoustic speaker device may receive and compare the first checksum set to a second checksum set comprising a plurality of checksums indicating units of the common audio playback signal in a playback queue of the second acoustic speaker device. The presence or absence of a match between the first and second checksum sets, as well as an offset, if any, of the match may indicate which acoustic speaker device is behind and by how many units. | 2013-10-10 |
