Patent number: 8571226Abstract: A sound reproducing device has a loudspeaker arranged to produce sound from an audio signal provided by an audio signal source. A microphone is positioned to pick up ambient noise and generate a microphone signal which comprises the noise. An ambient noise cancellation (ANC) system receives the microphone signal from the microphone and generates anti-noise corresponding to the ambient noise in the microphone signal. An automatic polarity adaptation (AAP) system monitors the ANC system and, when a decision criterion is fulfilled, causes a switch in polarity for the generated anti-noise.Type: GrantFiled: December 10, 2010Date of Patent: October 29, 2013Assignees: Sony Corporation, Sony Mobile Communications ABInventor: Peter Isberg

Publication number: 20090216352Abstract: 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.Type: ApplicationFiled: February 22, 2008Publication date: August 27, 2009Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Dag Glebe, Peter Isberg
