Speaker array and driver arrangement therefor

摘要

A driver arrangement for a speaker array (201) comprises a first and second driver (301, 303) each arranged with an on-axis direction at an angle to an on-axis direction of the speaker array (201). The first driver angle exceeds 5° and the second driver angle exceeds the first angle. A front section of each driver (301, 303) comprises a front edge of a radiating element and parts of the driver in front thereof. The drivers (301, 303) are arranged at least partly inline such that a first distance from a front axis (311) perpendicular to an on-axis of the speaker array (201), and intersecting a furthest forwards part of the first driver front section, to a closest part of the second driver front section is lower than a second distance from the front axis (311) to a furthest part of the first driver front section. The combination of angled drivers and the inline arrangement provides improved performance.

主权项

1. A driver arrangement for operation as one of a left and right sound source in a speaker array that defines a central forward on-axis and a front axis perpendicular to the central forward on-axis at a front portion thereof, the driver arrangement comprising:
a first driver sub-arrangement disposed on one side of the central forward on-axis of the speaker array, the first driver sub-arrangement comprising:
a first driver arranged with an first on-axis at a first angle outward from the central forward on-axis of the speaker array,
wherein the first angle exceeds 5°, andwherein the first driver (301) has a first driver front section comprising a first front edge, the first front edge has an inner forward part intersecting the front axis; anda second driver arranged with an second on-axis at a second angle outward from the central forward on-axis of the speaker array,
wherein the second driver has a second driver front section comprising a second front edge,wherein the second angle is larger than the first angle; wherein the first and the second drivers output audio signals in a substantially same frequency range; wherein a first distance defined as a closest distance from the front axis to the second front edge of the second driver is smaller than a second distance defined as a furthest distance from the front axis to the first front edge of the first driver; wherein a projected sideways distance defined as a distance along the front axis between an orthogonal projection from a first point corresponding to the furthest part of the front section of the first driver onto said front axis and an orthogonal projection from a second point corresponding to the closest part of the front section of the second driver onto said front axis, is between 25% and 75% of a difference between the second distance and the first distance.
