Patent ID: 8452040

Claim:
An audio speaker with a round-shaped built-in bass-reflex inside a closed cabinet, the speaker comprising: a cone-shaped diaphragm having a narrower end and a wider end, wherein the diaphragm is attached with the narrower end to a former to which is attached a voice coil that enters into a magnetic assembly and which voice coil produces a vibration of the diaphragm; a closed cone-shaped basket having a narrower and a wider end surrounding the diaphragm, wherein a space between the diaphragm and the basket increases towards the narrower ends of the diaphragm and basket; a first set of suspending connectors uniformly distributed around the wider end of the diaphragm for forming a space between the diaphragm and the basket, which serves as an entry area of the bass-reflex, the connectors being adapted to cushion the sound generated by themselves; a second set of suspending connectors of greater length than the length of the first set of connectors uniformly distributed around the narrower end of the diaphragm for creating a space between the diaphragm and the basket, the connectors being adapted to cushion the sound generated by themselves; and posts physically separating and defining a space between the basket and the magnetic assembly, the size of the space between the basket and the magnetic assembly defines an exit area of the bass-reflex through which an airflow created by the vibrations of the diaphragm passes through to the magnets and into the closed cabinet, and wherein a surface of the exit area of the bass-reflex corresponds in size to a surface of the entry area of the bass-reflex; wherein the first set of connectors and the second set of connectors connect the diaphragm and basket in such a way that the diaphragm operates as a sound radiating surface and as a first side of the bass-reflex and the basket forms a second side of the bass-reflex; and wherein the airflow between the diaphragm and the basket through the entry area of the bass-reflex, through the exit area of the bass-reflex and to the magnetic assembly cools the voice coil and the magnets.
