Abstract
A road vehicle having: a bottom wall, which, in use, faces a road surface; a body, which delimits a passenger compartment; and an aerodynamic sound generation system, which is configured to generate sounds making use of the head wind, namely the movement of air relative to the road vehicle generated by the forward movement of the road vehicle.
Claims20
A road vehicle (1) comprising:
- a bottom wall (6) which, in use, faces a road surface;
- a body (3) which delimits a passenger compartment;
- and
- an aerodynamic sound generation system (7);
- wherein the aerodynamic sound generation system (7) is configured to generate sounds making use solely of the action of the head wind, namely the movement of air relative to the road vehicle (1) generated by the forward movement of the road vehicle (1);
- and
- wherein the aerodynamic sound generation system (7) comprises at least one aerophone instrument (8) and a feeding device for conveying part of the head wind into the aerophone instrument (8);
- wherein the feeding device of the aerodynamic sound generation system (7) comprises an air intake (12), which is configured to intercept part of the head wind, and a feeding duct (13), which originates from the air intake (12) and leads to an inlet opening (10) of the aerophone instrument (8),
- wherein the aerodynamic sound generation system (7) comprises an adjustment valve (19), which is coupled to the feeding duct (13) and is configured to choke the passage of air along the feeding duct (13),
- wherein the adjustment valve (19) comprises:
- a pipe (20) having an inlet opening (21), which is axially arranged and faces the air intake (12), and a plurality of outlet openings (22), which are radially arranged;
- a plunger (23) mounted so as to move inside the pipe (20);
- and an elastic element (24) configured to push the plunger (23) towards the inlet opening (10) and towards a complete closing position, in which the plunger (23) is arranged between the inlet opening (10) and the outlet openings (22), and configured to be compressed by the pneumatic thrust exerted by the air upon the plunger (23) so as to allow the plunger (23) to reach a complete opening position, in which the plunger (23) is not arranged between the inlet opening (10) and the outlet openings (22).
