Speaker system
First Claim
1. A speaker system, comprising:
- a first speaker unit including a first speaker outputting a sound to be heard in a first listening position and a second speaker outputting a sound to be heard in a second listening position;
a second speaker unit including a third speaker outputting a sound to be heard in the first listening position and a fourth speaker outputting a sound to be heard in the second listening position;
a driver configured to independently drive at least the first speaker such that a current first listening position is substantially included in a vertical bisector plane of a line connecting an intersection of the first speaker and a directivity axis of the first speaker and an intersection of the second speaker and a directivity axis of the second speaker, and to independently drive at least the fourth speaker such that a current second listening position is substantially included in a perpendicular bisector plane of a line connecting an intersection of the third speaker and a directivity axis of the third speaker and an intersection of the fourth speaker and a directivity axis of the fourth speaker, wherein the first speaker unit and the second speaker unit are separated by a predetermined distance; and
a position detecting section that detects a current front-back position and a current reclining angle of a seat,wherein the driver further determines the current first listening position and the current second listening position according to a calculated head position of a seated listener in the seat, andwherein the calculated head position is calculated from the position detecting section that detects the current front-back position and the current reclining angle of the seated listener.

Abstract
A loudspeaker system capable of simultaneously providing listeners with a listening environment not giving them a feeling of strangeness. The loudspeaker system (100) comprises drive motors (111 to 113, 121 to 123) for so driving at least first R-channel loudspeaker (101) that the current first listening position is substantially included in the perpendicularly bisecting plane of a line joining the intersecting point of the first R-channel speaker (101) and its directivity axis and the intersecting point of the second R-channel loudspeaker (120) and its directivity axis and so driving at least fourth L-channel loudspeaker (104) that the current second listening point is substantially included in the perpendicularly bisecting plane of the line joining the intersecting point of a third L-channel loudspeaker (103) and its directivity axis and the intersecting point of a fourth L-channel loudspeaker (104) and its directivity axis. The loudspeaker system (100) further comprises their motor driver section (130).

9. A speaker system, comprising:
-
a first speaker unit including a first speaker that outputs a sound to be heard in a first listening position and a second speaker that outputs a sound to be heard in a second listening position; a second speaker unit including a third speaker that outputs a sound to be heard in the first listening position and a fourth speaker that outputs a sound to be heard in the second listening position; a motor driver configured to independently drive at least one first driving motor to move at least the first speaker such that a current first listening position is substantially included in a vertical bisector plane of a first line connecting a first point sound source of the first speaker along a directivity axis of the first speaker and a second point sound source of the second speaker along a directivity axis of the second speaker, and to independently drive at least one second driving motor to move at least the fourth speaker such that a current second listening position is substantially included in a vertical bisector plane of a second line connecting a third point sound source of the third speaker along a directivity axis of the third speaker and a fourth point sound source of the fourth speaker along a directivity axis of the fourth speaker, and a position detecting section that detects a current front-back position and a current reclining angle of a seat, wherein the motor driver further determines the current first listening position and the current second listening position according to a calculated head position of a seated listener in the seat, and wherein the calculated head position is calculated from the position detecting section that detects the current front-back position and the current reclining angle of the seated listener. - View Dependent Claims (10)
