The loader is comprised of a casing having a first face, one coupling member disposed in the first face, a primary storage disposed in the casing for storing a plurality of song data, and a transmitter for retrieving the song data from the primary storage to transmit the same through the one coupling member. The player is comprised of a housing having a second face arranged such as to confront the first face when the loader is placed in a coupled state with the player, another coupling member disposed in the second face in opposed relation to the one coupling member to thereby form a wireless coupler under the coupled state, a secondary storage disposed in the housing, a receiver for receiving the song data transmitted through the wireless coupler to store the same into the secondary storage, and a sound synthesizer responsive to a request for selectively retrieving a desired song data from the secondary storage so as to sound the karaoke accompaniment.
