Portable electronic device having an external speaker chamber
First Claim
1. A portable electronic device comprising:
- a case having a top portion and a bottom portion having a base surface;
a speaker disposed inside the case, having a front portion and a back portion;
wherein a back chamber is formed in association with the back portion of the speaker; and
a first aperture disposed through the bottom portion of the case;
an acoustic insulator attached to the base surface of the case;
wherein the acoustic insulator encircles the first aperture and an external chamber is defined at least by the base surface, and the acoustic insulator being adapted to rest upon a support surface upon which the portable electronic device rests;
wherein the external chamber is coupled to the back chamber by the first aperture.

Abstract
A portable electronic device, such as a portable notebook computer, that includes a case made up of a top portion and a bottom portion with a base surface. The case contains a speaker having a front portion and a back portion, where the back chamber is formed in association with the back portion of the speaker. A first aperture is disposed through the bottom portion of the case, and an acoustic insulator is attached to the base surface of the case such that the acoustic insulator encircles the first aperture forming an external chamber. The external chamber is defined by the base surface, and the acoustic insulator being adapted to rest upon a support surface upon which the portable electronic device rests. The external chamber is coupled to the back chamber by the first aperture.

15. A method for transmitting sound from a portable electronic device, comprising the steps of:
-
generating acoustic energy from a speaker by way of a vibrating member;
transmitting a first portion of the acoustic energy from the vibrating member through a speaker grill located in proximity to the vibrating member;
coupling a second portion of the acoustic energy from a rear surface of the vibrating member through an aperture on a surface to an external chamber formed by the surface, a supporting surface on which the portable electronic device rests, and an acoustic insulator which encircles the aperture and separates the surface from the supporting surface on which the portable electronic device rests.

20. A portable electronic device comprising:
-
a case having a top portion, a bottom portion, and side portions connecting the top portion and the bottom portion;
wherein the bottom portion defines a speaker grill at a base surface of the case; and
a speaker having a front portion and a back portion;
a support having an internal surface and an external surface located in proximity to the speaker grill within the case for supporting the speaker between the top portion and bottom portion of the case with the speaker oriented downward toward the speaker-grill, and the support acoustically isolates the front portion of the speaker from the back portion of the speaker;
a front internal speaker-chamber is defined by the base surface and the internal surface of the support and the front portion of the speaker;
wherein a back speaker-chamber is defined by the top portion and the external surface of the support and the back portion of the speaker;
a first aperture disposed on an exterior surface of the case to allow sound to be emitted from the back portion of the speaker;
a port tube disposed on the base surface;
an acoustic insulator attached to the bottom surface of the case;
wherein the acoustic insulator is formed around the port tube to form an external chamber coupled to the back speaker chamber by the port tube.
