<p>The present invention relates to a telescopic loudspeaker comprising a extendable telescopic body (1) responsible for housing a loudspeaker (2) for generating sound from a input audio signal and for creating a inner resonance chamber (2) of volume V0 when the telescopic body (1) is retracted and of volume V1 when the telescopic body (1) is extended, V1>V0 being met. The telescopic body (1) comprises: a support base (15); a plurality of hollow bodies (11,12,13) with decreasing transversal sections and coupleable to one another, the section decreasing progressively from the body (11) closest to the base (15) up to the body (13) furthest from the base (15); a gasket (8) between each pair of consecutive bodies (11,12,13) of the telescopic body (1) for sealing the air chamber inside the enclosure of the telescopic loudspeaker.</p> |
