Musical instrument with acoustic transducer

An acoustic transducer, which transforms an excitation signal generated by at least one resonator into an acoustic signal, wherein the acoustic transducer (11) is provided with an adjustable oscillation profile, where at least one profile parameter is defined by a reference profile (1) of a reference instrument (2) where the reference profile (1) is generated by the use of technical measuring means to record the sound of the reference instrument (2), and where the acoustic transducer (11), as part of a closed-loop control circuit, is connected to a difference former that evaluates the difference between the reference profile (1) and the acoustic transducer's (11) own characteristic profile (13), wherein the reference profile (1) is stored in a reference memory (7) which is coupled to a signal generator (8), wherein both the reference profile (1) and the characteristic profile (13) are each processed by the signal processor (8) as frequency response, wherein, after processing of the frequency responses of the reference profile and the characteristic profile, based on a difference between the frequency responses, the frequency response of the characteristic profile of the acoustic transducer is changed by the closed-loop control circuit in such a way that the difference between the frequency response of the reference profile and the frequency response of the characteristic profile is minimized,

• wherein the acoustic transducer (11) is adapted to a reference acoustic transducer in two stages,
• wherein the acoustic transducer (11) is adapted in a first stage with a linearized transmission function to a reference profile A and in a second stage under consideration of two frequency responses A and B with an intermediate nonlinearity to a reference profile B, and
• wherein the acoustic transducer (11) is designed as part of a musical instrument.
