Quite the opposite actually. If this was happening while connected to bluetooth I would suggest radio interference as the culprit.
Has the speaker been paired to your device before? If not the drops might be happening when the speaker is searching for a bluetooth connection. If it has and you are paired to the speaker as well as using the aux cord, that might be a contributing factor as well.
My suggestion is try it with bluetooth only and try it with the aux cord while bluetooth is disabled on your device. If the audio still cuts out it is beyond my paygrade.
