LOUDSpeakers
Once the laser and photocell has recreated the binary code, a electronic
circuit in the CD player (a digital to analog converter or DAC) decodes
these binary numbers and turnsthem into a changing pattern of electric
currents.
Once the binary codes are translated the electric currents make the loudspeaker porduce oscillations so you can hear sounds! Turning electric energy to sound energy!

In detail
An electromagnet is in a constant magnetic field. Two magnets the electromagnet and permanent magnet interact with each other. When their orientations switch (positive and negative attract then negative and negative repel) the speaker coil vibrates repeatedly. This pushes the speaker cone (bit outside). The air in front vibrates which creates sound waves!The frequency and amplitude is determined by the diaphragm.
