Acoustic loudspeaker comprising a cabinet and a rotary mounted speaker

An acoustic loudspeaker comprising a cabinet extending along a direction, and at least one speaker mounted on the cabinet, the speaker comprising a frame, and a membrane adapted to emit sound waves, the membrane being movable relative to the chassis along an acoustic axis of the speaker, the cabinet defining a first axis perpendicular to the direction, and a second axis perpendicular to the direction and to the first axis, the acoustic loudspeaker being intended to be used at least in a first configuration, wherein the first axis is substantially vertical, and a second configuration, wherein the second axis is substantially vertical, the speaker being movable with respect to the cabinet in rotation around an axis of rotation between a first position, intended to be occupied when the acoustic loudspeaker is in the first configuration and wherein the acoustic axis defines with the second axis a first angle less than 30° in absolute value, and a second position, intended to be occupied when the acoustic loudspeaker is in the second configuration and wherein the axis acoustic defines with the first axis a second angle less than 30° in absolute value, the axis of rotation defining with the first axis a third angle comprised between 40° and 50° in absolute value, and with the second axis a fourth angle comprised between 40° and 50° in absolute value.
