20110029106 | METHOD AND ARRANGEMENT IN A MOBILE TERMINAL - A method in a mobile terminal, for rendering audio content of a media file, is provided, in which the mobile terminal includes a vibrator for generating vibrations at a particular frequency, based on a voltage applied to the vibrator. The method includes reading the audio content of the media file, identifying signals representing bass tones of the audio content, recognizing the frequency of the bass tones, checking if the frequency is within an operating range of the vibrator; if so, calculating a particular voltage to apply to the vibrator, and applying the calculated voltage to the vibrator, and providing feedback of the vibrator generated frequency, to aid the calculating unit in adjusting the applied voltage for causing the vibrator to generate vibrations at the recognized frequency when the identified bass tones of the media file are rendered. | 02-03-2011 |
20110064251 | SPEAKER AND VIBRATOR ASSEMBLY FOR AN ELECTRONIC DEVICE - Vibration generation for an electronic device is performed by a speaker and vibrator assembly. In an audio mode, the assembly may be used to output audio, such as ringtones, alerts, music, and so forth. In a vibration mode, speakers of the assembly drive movement of a weight. The movement of the weight results in user-detectable vibration of the electronic device. Also, audio and vibration may be output at the same time by using a signal that includes an audio component and a signal that results in movement of the weight. | 03-17-2011 |

The vibration apparatus comprises a first weight member; a second weight member; a driving section coupled to said first weight member and operable to rotate at least said first weight member around a rotation axis; and a coupling mechanism adapted to provide coupling between said first weight member and said second weight member so that in a first state said first weight member is rotated by said driving section and in a second state said first weight member and said second weight member are rotated by said driving section. | 06-09-2011 |
20110216013 | Touch-sensitive input device, touch screen device, mobile device and method for operating a touch-sensitive input device - The invention relates to a touch-sensitive input device, a touch screen device, a mobile device and a method for operating a touch-sensitive input device to provide for a more realistic haptic feedback to a user in response to an input. The touch-sensitive input device comprises a first layer, a second layer facing said first layer, said first and second layers defining a cavity accommodating a substance capable of flowing, and an actuator device arranged to vary the pressure of said substance in said cavity so as to provide haptic feedback to a user touching a surface of said touch-sensitive input device. | 09-08-2011 |
20120163625 | METHOD OF CONTROLLING AUDIO RECORDING AND ELECTRONIC DEVICE - A method of controlling audio recording using an electronic device and an electronic device are described. The electronic device comprises a microphone arrangement having a directivity pattern. A target direction relative to the electronic device is automatically determined in response to sensor data representing at least a portion of an area surrounding the electronic device. The microphone arrangement is automatically controlled in response to the determined target direction to adjust an angular orientation of the directivity pattern relative to the electronic device. | 06-28-2012 |
20120259628 | ACCELEROMETER VECTOR CONTROLLED NOISE CANCELLING METHOD - A telecommunication device is disclosed, comprising: a microphone array comprising a plurality of microphones, wherein each microphone receives an analogue acoustic signal; a position sensing device for determining how the telecommunication device is positioned in three-dimensions with respect to a user's mouth; at least one analogue/digital converter for converting each analogue acoustic signal into a digital signal; a digital signal processor for performing signal processing on the received digital signals comprising a controller, a plurality of delay circuits for delaying each received signal based on an input from the controller and a plurality of preamplifiers for adjusting the gain of each received signal based on a gain input from the controller, wherein the controller selects the appropriate delay and gain values applied to each received signal to remove noise from the received signals based on the determined position of the telecommunication device. A method for creating and controlling a location of a virtual microphone near a telecommunication device so as to reduce background noise in a speech signal is also disclosed. | 10-11-2012 |
