Embodiment Construction

[0060] Figure 1A shows an embodiment of the structure and layout of components of an acoustic transducer. The assembly includes three stacked acoustic transducers 10, 20, 30 for receiving and reproducing acoustic signals, the first acoustic transducer 10 having a direction along the horizontal front / rear direction (here, along the X coordinate axis direction) Figure 8 directional patterns, and include semi-directional patterns XA, XB. The second acoustic transducer 20 has a figure-of-eight directional pattern along the horizontal right-left direction (along the direction of the Y coordinate axis), including semi-directional patterns YA, YB. The third acoustic transducer 30 has an up / down directional pattern in the direction of the Z coordinate axis, has a circular shape when viewed along the XY plane, and includes semi-directional patterns (ZA, ZB). In this component, the center points are as close to each other as possible, however, they overlap each other as little as possi...

Abstract

The invention relates to an assembly of acoustic transducers, a system and a method for receiving and reproducing sound. The assembly comprises a first acoustic transducer having a directional pattern of the shape of a figure of eight in the direction of an X axis of a XYZ coordinate system, and a second acoustic transducer placed perpendicularly relative to a first capsule and providing a directional pattern of the shape of a figure of eight in the direction of a Y axis of a XYZ coordinate system. The assembly is characterized in that it further comprises a third acoustic transducer placed perpendicularly relative to the first and second acoustic transducers, enabling the implementation of spatial sound both in a XY plane and in a XYZ plane by using these acoustic transducers placed in accordance with an axis of the axes of the XYZ coordinate system. The invention further provides a system and a method for processing signals received with the assembly.

Description

technical field [0001] The present invention relates to techniques for recording and reproducing spatial sound. Background technique [0002] As home theaters become more commonplace, most consumers own one. Home theaters are designed to reproduce reliable spatial sound, as in the case of recording. Currently, this setup is most commonly of the 5.1 type, consisting of two front speakers, a center speaker, two rear speakers, and a subwoofer controlled by an LFE channel for low frequency effects. Other such surround systems include 7.1, 8.1 and 10.2 systems, some of which are designed, for example, only for theater use and not for general consumer use. However, such a 5.1 device requires six channels and does not include elevation information. In such systems, the loudspeakers are positioned at designed locations around the listener. [0003] However, it is actually impossible to reproduce sound that matches the situation of the original recording, and thus, a technique fo...
