In a simplified sound-reproducing device, a motor is coupled by a transmission to a record disc for driving the record disc and an external output shaft extending outside from the casing of the device. Transmission consists of a driving wheel fixed to an extension of a center shaft and a follower wheel fixed to the output shaft which is disposed parallel to the center shaft. The driving wheel and the follower wheel are arranged to either mesh or not mesh with each other depending on their relative relationship in the axial direction by caused axial shifting of the center shaft. Virtue of the construction as mentioned above, the device can drive, by relying on the driving motor alone, another device or attachment subsequent to or concurrent with sound reproduction.
