Abstract: A method for diagnosing sealing properties of microphone and/or loudspeaker seals in an electronic device. Sealing properties of the microphone and/or loudspeaker seals are diagnosed by comparing a representation of a total impulse response signal associated with certain stimuli with a representation of a predetermined reference total impulse response signal associated with the electronic device.

Abstract: 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.

Abstract: 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.

Abstract: To control a display of a portable electronic device, data are retrieved which are indicative of a temperature variation over the display. The retrieved data are processed to generate a temperature chart for the display, the temperature chart being indicative of a temperature profile which is spatially varying in a display plane. The display is controlled in a spatially varying manner in accordance with the generated temperature chart.

Abstract: A method for determining an impedance of an electroacoustic transducer (13) is provided. The electroacoustic transducer (13) is to be arranged in an ear channel of an ear (19) of a user. According to the method, an output signal is supplied to the electroacoustic transducer (13) and an input signal indicating an impedance of the electroacoustic transducer (13) in response to the supplied output signal is determined. A filtered output signal is generated by filtering the output signal with a bandpass filter having a predetermined frequency range. A filtered input signal is generated by filtering the input signal with a bandpass filter having the predetermined frequency range. Based on the filtered output signal and the filtered input signal the impedance (21, 22) of the electroacoustic transducer (13) is determined for the predetermined frequency range.

Abstract: The present invention relates to a vibration apparatus, a hand-held mobile device and a method for operating the vibration apparatus with which the time to obtain a detectable vibration effect is reduced while still being able to provide also a strong vibration effect. 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.

Abstract: 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.
