Assembly for transmitting airborne acoustic waves, which can be combined with a musical wind instrument having side holes

An airborne acoustic wave transmission assembly configured to be combined with a musical wind instrument with side holes comprising a tubular body defining an air column, the tubular body extending locally substantially along a first axis (X), said transmission assembly being configured to be disposed removably inside the tubular body of the instrument, the transmission assembly comprising:

• An emitting device (E) for emitting airborne acoustic waves in the air column comprising:
• a first fixing structure for fixing to the tubular body of the instrument;
• an actuator configured for transforming an electrical signal into airborne acoustic waves that propagate in the air column;
• an intermediate element for fixing the actuator to the first fixing structure configured to separate the actuator from the tubular body;
• an airborne acoustic wave reception device (R) comprising:
• a second fixing structure for fixing to the tubular body of the instrument;
• a microphone linked to the second fixing structure, the microphone being configured for receiving, after the propagation thereof in the air column, the airborne acoustic waves emitted by the actuator, the microphone being positioned off-center with respect to the first axis (X);
• a transformation device linked to the second fixing structure and configured for transforming the airborne acoustic waves received by the microphone into an electrical signal characterizing a configuration of plugging of the side holes of the instrument,
• the tubular body comprising a stop, in which the first fixing structure comprises a guideway, the guideway being configured to guide the emission device (E) along the tubular body to the stop.
