Claim of US Patent No. 10,919,621

1. An unmanned air vehicle, comprising:one or more generators, each of which generates a force that drives the unmanned air vehicle to fly and also generates an air flow;
one or more first structural components;
one or more microphones, each of which outputs a first signal;
one or more speakers; and
a processor that generates one or more second signals according to the first signal output from each of the one or more microphones,
wherein the one or more first structural components respectively correspond to the one or more generators, respectively surround one or more rotary wings of the one or more generators, and each includes a through-hole extending in a direction of the air flow generated by a corresponding one of the one or more generators, the through-hole being in a first direction opposite to a second direction of the air flow,
a first end, in the first direction, of the one or more first structural components and a first surface of a rotation plane, in the first direction, of the one or more rotary wings are aligned such that the one or more rotary wings are covered by a first end part of the one or more first structural components, the first end part corresponding to a position of the one or more rotary wings,
a second end, in the second direction of the air flow, of the one or more first structural components is extended, in the second direction of the air flow, beyond a second surface of the rotation plane, in the second direction of the air flow, of the one or more rotary wings by a length longer than the first end part,
each of the one or more microphones is located in an inner region surrounded by a corresponding one of the one or more first structural components such that each of the one or more microphones is spaced apart in the second direction of the air flow from a corresponding one of the one or more generators, and
each of the one or more speakers is located apart in the second direction of the air flow from a corresponding one of the one or more generators and outputs a sound according to a corresponding one of the one or more second signals.
