I've made a telvisor, which is working good. Except that the motor causes some noise in the (big) loudspeaker. The coil of the loudspeaker is less than 10 cm from the motor.
What is the best way to suppress the noises? A capacitor between the two contacts of the motor? If yes, which one? Another solution would be a sheet of copperfoil between motor and loudspeaker. But that is not very elegant...
Replacing the loudspeaker is not an option, a smaller loudspeaker would work (I've tried it), but of course would not have that good sound.
