  • Sound device provided with a geometric and electronic radiation control
    Patent number: 7426278
    Abstract: A sound device for carrying out a homogenous sound cover for a public addressed area includes an electroacoustic source network (1), wherein each electroacoustic source (1) diffuses a version delayed by a delay (3), filtered by a filter (4) and amplified by the device input signal amplifier (5). The network is substantially rectilinear and vertical, angles ? which are formed by the emitting axes of the electroacoustic sources (1) and a normal to the network are selected such that ?n>?n?1, wherein n is the index of the electroacoustic sources (1) numbered in ascending order from the top of the device to the bottom thereof and the delays (3) interact with the angles ? in such a way that the device generates a wavefront (6) whose shape corresponds to the desired sound cover of the public addressed area.

  • Device for obtaining quarter-tones and other micro-intervals on musical wind instruments with lateral holes
    Patent number: 4714001
    Abstract: For each register of the instrument, the device comprises at least one auiary tube branched in the vicinity of the head of the instrument and a manual control mechanism making it possible to open or close the auxiliary tube at its first end in contact with the instrument or at its second end turned towards the outside.This device more particularly applies to flute mouthpiece instruments or reed instruments, such as clarinets, saxophones, oboes and bassoons.
