Just to be a pedant, the android phone I am typing this on is also made entirely out of electrical and electronic parts as well. In fact, arguably this device contains a greater degree of those parts, as the only electromechanical parts are speakers, a vibration motor, and 3 tact switches.

A simple radio will have a speaker, slide switch for power, potentiometer for volume, and either a potentiometer or variable cap for tuning.

Although I do agree, the operative words there are 'simple' and 'no firmware'. ;)
