Abstract: A speaker (20) includes a cabinet (21) extending along a longitudinal axis (X) between a first and a second end (21a, 21b). The cabinet (21) includes a side wall surrounding an internal volume and provided with an opening to place the internal volume in communication with an outside environment. The speaker (20) also includes a sound transducer (22) and a connection circuit (23) configured to receive a signal and to transmit the signal to the sound transducer (22). The speaker (20) also includes a first and a second passive resonator (24, 25) each including a vibrating panel (24a, 25a). The vibrating panels (24a, 25a) are positioned in the internal volume, with respective first faces facing each other and respective second faces opposite the first faces. The internal volume includes a first, closed air volume (V1) delimited by an inside surface of the cabinet (21) and by the second faces of the vibrating panels (24a, 25a). The internal volume also includes a second air volume (V2), delimited by the first faces of the vibrating panels (24a, 25a) and open towards the outside environment through the opening.
