Abstract: Electronic devices and methods are disclosed that adaptively filter a microphone signal responsive to vibration that is sensed in the face of a user speaking into a microphone of the device. An electronic device can include a microphone, a vibration sensor, a vibration characterization unit, and an adaptive sound filter. The microphone generates a microphone signal that can include a user speech component and a background noise component. The vibration sensor senses vibration of the face while a user speaks into the microphone, and generates a vibration signal containing frequency components that are indicative of the sensed vibration. The vibration characterization unit generates speech characterization data that characterize at least one of the frequency components of the vibration signal that is associated with the speech component of the microphone signal.

Abstract: An electronic device includes a force sensor that is configured to generate a force signal that indicates an amount of force being exerted thereon by a user, and a controller circuit that is configured to control a volume and/or rate that an audio signal is broadcast by a speaker responsive to the force signal.

Abstract: The invention is directed to systems, methods and computer program products for producing audible sound by directing ultrasonic signals from an ultrasonic transducer towards an eardrum. An exemplary method includes providing an earphone comprising an ultrasonic transducer, wherein the earphone is positioned close to an ear, wherein the ear includes an ear canal and an eardrum; producing, by the ultrasonic transducer, an ultrasonic signal; and transmitting, by the ultrasonic transducer, the ultrasonic signal, wherein the ultrasonic signal is directed into the ear canal towards the eardrum such that the eardrum receives the ultrasonic sound signal and initiates conversion of the ultrasonic signal into audible sound.

Abstract: The present invention relates a method and a mobile communication device for generating an adaptive ring signal level in the mobile communication device in response to the surrounding environmental condition of said mobile communication device and also in response to the way the mobile communication device is stored away. By comparing a transfer that is determined based on the relation between an emitted signal from the loudspeaker and a response recorded by the microphone and an ideal transfer function a calculated response function is obtained. The calculated response function is compared with predefined response functions stored in a look up table to find a match that is then selected. The ring signal is thereafter adjusted to a level that corresponds to the values associated with and stored together with the selected predefined response function.

Abstract: The invention relates to a portable device with an enhanced stereo image, and more particularly a device in which an unsymmetrical placement of loudspeakers is compensated by means of electronic adjustment of the phase and level of the sound. The present invention provides a device (1) comprising a sound source outputting audio channels in stereo, a sound reproduction system delivering electronic sound signals based on the audio channels to at least two loudspeakers (2, 3) for sound reproduction with a stereo image. The device further comprises means for adjusting the level and phase of one of the sound signals to one loudspeaker (2).

Abstract: The invention relates to handling disturbing sounds produced by the camera module during video recording. In particular the invention relates to a method for elimination of camera sounds in an audio signal of a video recording comprising the steps of; providing a transient pulse pattern representing a camera sound, comparing the transient sound with the audio signal, detecting if the audio signal correspond to the transient pulse pattern based on the comparison and filtering the transient pulse pattern from the audio signal where a correspondence has been detected. The invention also relates to a corresponding device.

Abstract: 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.

Abstract: The present invention provides adapting an audio frequency range to a linear vibrator. This may be achieved by detecting presence of signal components in a first audio frequency range. A control signal may then be provided in response to the detected first signal components. A second signal component in a second frequency range may moreover be obtained and controlled in response to the amplitude of the control signal, wherein the second frequency range is narrower than the first audio frequency range. Feeding of the controlled second signal component to the linear vibrator causing vibrations of the linear vibrator is thus enabled, creating an increased experience of the music when applied to rhythm-based music within a portable communication device such as a mobile phone.
