AI Technical Summary

Technical Problem

Conventional loudspeaker systems require multiple loudspeaker units for stereophonic reproduction, leading to bulkiness and complexity, and lack effective depth and width effects in sound reproduction.

Method used

A compact loudspeaker arrangement with a front, left, right, and rear loudspeaker units, where the front and rear units are connected in series with opposite polarity, and the left and right units share the same polarity, creating a depth and width effect through sound cancellations and reflections.

Benefits of technology

The arrangement achieves stereophonic reproduction with a single unit, providing spatial depth and width effects by utilizing sound reflections and cancellations, enhancing the perceived sound origin and instrument positioning.

Abstract

The invention relates to a loudspeaker arrangement (1) for stereophonic reproduction of acoustic signals, comprising a front loudspeaker unit (3) with a front radiation axis (4) that can be directed towards a target listening area, a left loudspeaker unit (6) with a left radiation axis (7) oriented in a horizontal projection plane transverse to the front radiation axis, and a right loudspeaker unit (9) with a right radiation axis (10) oriented in the horizontal projection plane transverse to the front radiation axis, wherein the front loudspeaker unit (3) and the left loudspeaker unit (6) are connected in series in a left audio channel (L) of the loudspeaker arrangement (1), and the front loudspeaker unit (3) and the right loudspeaker unit (9) are connected in series in a right audio channel (R) of the loudspeaker arrangement (1).To provide a novel and compact loudspeaker arrangement (1), it has a rear loudspeaker unit (16) with a rear radiation axis (17) directed away from the target area, wherein the rear loudspeaker unit (16) and the left loudspeaker unit (6) are connected in series in the left audio channel (L) of the loudspeaker arrangement (1), and the rear loudspeaker unit (16) and the right loudspeaker unit (9) are connected in series in the right audio channel (R) of the loudspeaker arrangement (1), and wherein the left loudspeaker unit (6), the right loudspeaker unit (9) and the rear loudspeaker unit (16) are connected with the same polarity, and the front loudspeaker unit (3) is connected with opposite polarity to the left loudspeaker unit (6), the right loudspeaker unit (9) and the rear loudspeaker unit (16).
