Speaker front volume usage

A speaker assembly comprising:

• an enclosure having a top wall, a bottom wall, a sidewall connecting the top wall to the bottom wall, an acoustic output opening and a back volume defined by the top wall, the bottom wall and the at least one sidewall;
• a speaker driver positioned within the enclosure, the speaker driver comprising a sound radiating surface having a top face and a bottom face for emitting sound waves therefrom, wherein an area between the top face of the sound radiating surface, the top wall of the enclosure and the at least one side wall of the enclosure defines a front volume area within the enclosure;
• and
• a frame member attached to the speaker driver, the frame member forming a front volume chamber acoustically coupling the top face of the sound radiating surface to the acoustic output opening and a back volume chamber acoustically coupling the bottom face of the sound radiating surface to the back volume, wherein an area defined by the front volume chamber is less than the front volume area.

A portable audio electronic device comprising:

• an enclosure having a top wall, a bottom wall, a sidewall connecting the top wall to the bottom wall, an acoustic output opening and a back volume, wherein the back volume is defined by the top wall, the bottom wall and the sidewall;
• a speaker driver positioned within the enclosure, the speaker driver comprising a sound radiating surface having a top face and a bottom face for emitting sound waves therefrom;
• and
• a frame member attached to the speaker driver, the frame member forming a front volume chamber acoustically coupling the top face of the sound radiating surface to the acoustic output opening and a back volume chamber acoustically coupling the bottom face of the sound radiating surface to the back volume, wherein the back volume chamber comprises a segment that overlaps one of the top face or the bottom face of the speaker driver.

An electronic audio system comprising:

• an enclosure having a top wall, a bottom wall, a sidewall connecting the top wall to the bottom wall, an acoustic output opening and a back volume, wherein the back volume is defined by the top wall, the bottom wall and the sidewall;
• a speaker driver positioned within the enclosure, the speaker driver comprising a sound radiating surface having a top face and a bottom face for emitting sound waves therefrom;
• and
• a frame member attached to the speaker driver, the frame member forming a front volume chamber acoustically coupling the top face of the sound radiating surface to the acoustic output opening and a back volume chamber acoustically coupling the bottom face of the sound radiating surface to the back volume, wherein a portion of the back volume chamber overlaps a side of the speaker driver that is facing the acoustic output opening such that a volume of the back volume chamber is greater than a volume of the front volume chamber;
• a memory to store an operating system program;
• and
• a processor coupled to the memory to execute the operating system program and to send an audio signal to the speaker.
