    摘要： The invention is directed to systems, methods and computer program products for adjusting audio properties after recording an audio. An exemplary method includes recording audio using an audio capturing system, wherein the recorded audio is associated with an audio level; determining one or more audio signal properties associated with the recorded audio; comparing the audio level with a first predetermined threshold level; and in response to determining the audio level is greater than a first predetermined threshold level, adjusting the recorded audio based at least partially on modifying the one or more determined audio signal properties, wherein the adjusting step is performed a finite time interval following the recording step.

    摘要： 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.

    摘要： An elongation ring adapted for use in a self-ventilated traction motor and for fixed placement between the non-driving end of the motor housing and a motor end shield. The ring has radial air outlet openings placed along its circumference and is adapted to enclose a fan wheel fixed on a motor driving shaft. A traction motor having such an elongation ring is also contemplated. The elongation ring provides a possibility to easily adapt a motor housing to different motor types such as a self-ventilated motor with the ring, or one with forced ventilation without the ring.

    摘要： An electronic device includes a housing comprising a speaker configured to be positioned adjacent an ear of a user, and a position-sensitive region on the housing that is configured to sense a position of the ear of the user relative to the housing when the ear is positioned adjacent the speaker and to generate an acoustic leakage position signal responsive to the sensed position of the ear of the user. A control unit is in communication with the speaker and the position-sensitive region and is configured to provide an electrical input signal to the speaker. 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.
