Abstract (en)

A retractable speaker structure for use in a vehicle is provided. The retractable speaker structure (10) includes: a case (1) formed with a chamber (11); a driving member (2) installed in the chamber (11) and including a stepping motor (21) and a transmission shaft (22) connected to the stepping motor (21); a retracting mechanism (3) disposed in the chamber (11) and including a screw rod (31) and a retractable rod (32) fitted with the screw rod (31). The screw rod (31) is driven by the transmission shaft (22) to rotate, thereby enabling the retractable rod (32) to perform a protruding/retracting movement relative to the screw rod (31); and a speaker (4) secured at an end section of the retractable rod (32) and moved with the retractable rod (32). Accordingly, the retractable speaker structure (10) is able to be adjusted for being protruded or retracted according to the actual needs.
