Abstract:
In a method and device for generating and/or displaying 3D images the depth of content (d) of an image or a part of an image is temporarily increased to a high level (h) where after the depth of content is decreased to a low level (1). This temporary increase of the depth of content renders a large 3D effect to the image or the part of the image to which it has been applied. It has been found that this enhancement effect of an increased 3D effect lingers on in the perception of the viewer even after application. The actual average depth of content can be made relatively low thus reducing fatigue, while the perceived depth of content is relatively high.
Abstract:
A thermo-acoustic transducer device (8) comprises a substantially hollow body (10) in which a thermo-acoustic element (11) is accommodated, and a heating control unit (2) coupled to the thermo-acoustic element (11) for controlling the temperature gradient of the element. A loudspeaker (14) is acoustically coupled to the hollow body (10). The heating control unit (2) may be arranged for being controlled by a control signal produced by a quality control unit (5) so as to control the quality iactor (Q) of the thermo-acoustic device. The quality control unit (5) may be coupled to an audio amplifier (4) to control the quality factor in dependence of properties of an audio signal.

Abstract:
A loudspeaker (1) having a conductive suspension section (3) and two electrodes (5, 6) is controlled by generating a measuring current in the conductive suspension section (3), detecting the voltage thus generated, and using the voltage to control the output power to the loudspeaker. The control method and device may be used for loudspeaker protection, motional feedback and limiting the output power. The conductive suspension section (3) may be part of the rim of the loudspeaker and may be made of conductive rubber.
Abstract:
A device (1) is arranged for adjusting the amplitude of an audio signal (x) such that the output of a transducer (2) coupled to the device is equivalent to the output of a reference transducer. The device comprises a first simulation unit (11) for producing a reference signal (y) in response to the audio signal (x), a second simulation unit (12) for producing a further signal (z) in response the audio signal (x), and comparator means (15) for comparing the reference signal (y) and the further signal (z) so as to produce an adjustment signal (a) which is fed to an adjustment unit (10). The first simulation unit (11) simulates the response of a reference transducer, while the second simulation unit (12) simulates the response of the actual transducer (2) to the audio signal (x).

As a reproduction quality the position of a virtual sound source and the quality of a stereo signal are also possible.

Abstract:
An apparatus (1) comprising a display screen (150), the apparatus (1) further comprising means (24) for activating said display screen (150) to serve as a loudspeaker for reproducing an audio signal (A), means (20) for detecting if said display screen (150) is viewed by a user of the apparatus, and means (22) for adjusting the reproduction of said audio signal (A) in order to reduce display distortion in dependence on said detecting (20) if said display screen (150) is viewed. An advantage of reproducing an audio signal (A) according to the invention is that audio properties normally causing optical distortion in the display screen (150) may be reproduced in situations where the user is not able to perceive the optical distortion. These audio properties may contribute to an advantageous reproduction of the audio signal (A).
Abstract:
The present invention relates to a method and a media system of/for generation of at least one output signal (HPL, HPR) from at least one input signal from a second set of sound signals (M) having a related second set of Head Related Transfer Functions. The media system can be a TV, a CD player, a DVD player, a Radio, a display, an amplifier, a headphone or a VCR. Said method includes the steps of determining, for each signal in the second set of sound signals, a weighted relation (14) comprising at least one signal from a third set of intermediate sound signals (CHI1, CHI2) and at least one weight value (Weights); determining a first set of Head Related Transfer Functions (HRTFs) based on the second set of sound signals, the second set of Head Related Transfer Functions and the weighted relation; and transferring at least one signal from the third set of intermediate sound signals by means of at least one HRTF from said first set of Head Related Transfer Functions in order to generate at least one output signal belonging to said first set of sound signals. Hereby, in the end, fewer HRTFs are determined for a subsequent transfer of input signal(s) to output signal(s). Accordingly few convolutions are required.
