ABSTRACT:
An audio apparatus in the form of a radio receiver is composed of a first part including electrical components constituting a tuner housed within a first cabinet for providing audio signals, a second part including at least a loud speaker housed within a second cabinet for converting the audio signals to sound, and cooperative mechanical and electrical coupling members at mating surfaces of the first and second cabinets for detachably assembling together the first and second parts of the apparatus with such mating surfaces of the respective cabinets in abutting relationship. When the first and second parts of the audio apparatus are detached from each other, the first part thereof may be used alone as a pocket radio with the audio signals produced thereby being audibly reproduced by means of an earphone engaged with a respective jack of such first part. Further, when the first part is detached from the second part, a casing or cover can be engaged with the mechanical coupling member of the first part for protecting the detached first part.
