A loudspeaker system for vehicle has a wall of a frame of a vehicle that separates an exterior from an interior and has a through hole, a box mounted in the wall in correspondence of the through hole, a loudspeaker mounted in the box, a back resonance chamber formed between the membrane of the loudspeaker and the walls of the box, a through hole obtained in a wall of the box and disposed in register with the hole of the wall of the frame of the vehicle and a partition of sound-absorbing material that closes the through hole of the wall of the box.

Loudspeaker system for vehicle

A fume extractor hood is disclosed, comprising a box with a motor-fan assembly and a muffler module comprising a bearing frame defining an air extraction conduit with axis (A), an active noise suppression system comprising at least one electro-acoustic transducer and at least two microphones, a passive noise suppression system comprising a sound absorbent material. Said muffler module comprises at least two electro-acoustic transducers connected to the walls of said bearing frame, in opposite positions, in such manner to leave the central part of said conduit free. The sound beams coming from said at least two electro-acoustic transducers are mutually combined, obtaining a resulting sound beam that can be directed towards a preferred direction by means of beam forming algorithms.

Low-noise fume extractor hood

A muffler unit for a fume extractor hood includes an active noise suppression system, at least one loudspeaker, and at least two microphones connected to a control unit, and a passive noise suppression system having sound-absorbent material disposed between the microphones. The muffler unit further includes a conduit with upper fixing element and lower fixing element designed to be removably fixed to a motor unit and to a conveyor plate of the hood.
