Gimbal-mounted linear ultrasonic speaker assembly
First Claim
Patent Images
1. An apparatus, comprising:
- at least one speaker mount;
plural ultrasonic speakers arranged on the speaker mount and spaced vertically from each other, each ultrasonic speaker being configured to emit sound along a respective sonic axis;
a gimbal assembly coupled to the speaker mount;
at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor to;
receive a control signal representing motion of an object in a computer simulation; and
responsive to the control signal, actuate the gimbal assembly to move the plural ultrasonic speakers such that the sound axes move azimuthally.

Abstract
Audio spatial effects are provided using a gimbal-mounted ultrasonic speaker array in which a vertical line of ultrasonic speakers are provided on a speaker mount and are angled to direct sound at respective different elevation angles. The speaker mount can be rotated by a gimbal. In this way, the azimuth angle of the linear array is established in response to a control signal from, e.g., a game console or video player, with elevational angle of the desired sound beam being established by selecting one or more of the speakers in the linear array with the appropriate elevation angle.
