Abstract
An acoustic device for use in a wearable device (e.g., smart watch) is described. The acoustic device includes a curved primary audio waveguide and a plurality of secondary waveguides. The curved primary waveguide has two ports that open to a local area on opposite ends of the primary audio waveguide. The primary waveguide is coupled to a plurality of secondary audio waveguides. Each secondary audio waveguide couples a different acoustic sensor to the primary audio waveguide. A controller can select a signal from an acoustic sensor, of the at least two acoustic sensors, having the least amount of wind noise. Additionally, in some embodiments, when there is minimal wind noise, the at least two acoustic sensors may be used for beamforming.
