## Title
Integrated speaker enclosures for electronic devices

## Abstract

Integrated speaker enclosures for electronic devices. A device chassis portion with an inner face and an outer face can be connected with a speaker enclosure portion with an inner face, an outer face, and edges. The edges match the inner face of the device chassis portion to provide an audio enclosure when the speaker enclosure portion is aligned with and in contact with the device chassis portion.

## Background
TECHNICAL FIELD
Embodiments of the invention relate to speakers in electronic devices. More particularly, embodiments of the invention relate to speaker enclosures/boxes for speakers in electronic devices.
BACKGROUND
The design of acoustics and speakers on electronic systems (e.g., smart phones, ULTRABOOKSTM, tablets and all-in-ones) are often designed as ‘drop-in’ solutions that do not fully utilize available internal volume or achieve best/premium audio output. This leads to a compromised audio experience that in inconsistent with the trend for high quality visual experience. Thus, current audio solutions do not provide an optimal user experience. ULTRABOOKTM is a trademark of Intel Corporation in the United States and/or other countries.

DETAILED DESCRIPTION
In the following description, numerous specific details are set forth. However, embodiments of the invention may be practiced without these specific details. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description.
By utilizing the back-skin (chassis) of a system as one or more sides of the acoustic enclosure with a speaker improved audio performance can be achieved. Further, this can intricately grab internal volume between major system components. As a consequence weight, thickness and overall dimensions of the acoustic module are reduced while grabbing the maximum volume available between system components for acoustic advantage. By combining various chassis materials with acoustic module material (e.g., polyurethane, plastic) better acoustic performance can be achieved. Because a large ‘x’-‘y’ surface is available in case of all-in-one systems, overall vibration is dampened using this approach.
The use of this approach delivers more compact form factors with reduced thickness and/or weight or leverages existing dead system volume for an enhance audio experience. Vibration (while playing high Sound Pressure Levels) is absorbed into the chassis, which acts as a damper. The embodiments and strategies described can be used in any form factor—especially in smaller form factor devices like smartphones, tablets or ULTRABOOKSTM where available volume for acoustic module is very limited. By using these embodiments, potential increase in acoustic volume could be achieved without impacting overall system volume.
The examples that follow in FIGS. 1A, 1B, 2A, 2B, 3A and 3B illustrate only a portion of a chassis for an electronic device and none of the electronics. This is for reasons of simplicity as any type of electronic device having speakers can be enclosed in the chassis. For example, the electronic device can be a desktop computer system, a laptop computer system, an ULTRABOOKTM, a tablet, a smartphone, a mobile audio device, a portable television, or a video playback device. An example block diagram of an electronic device is provided in FIG. 4. The techniques described herein are also applicable to non-electronic applications as well, for example, furniture, wireless speakers, automobiles, headphones, etc.
Further, the examples of FIGS. 1A, 1B, 2A, 2B, 3A and 3B illustrate a rear chassis portion being utilized with a speaker enclosure portion to provide an audio enclosure. This is but one example embodiment. Other examples can utilize a front chassis portion in a similar manner. Other examples can include side chassis portions. As discussed above use of the speaker enclosure portion with a chassis allows for a greater audio enclosure volume than use of a complete speaker enclosure housed within the chassis.
FIG. 1A is a perspective-view illustration of an outer view of a backside chassis portion and a partial speaker enclosure. In the example of FIG. 1A, chassis portion 100 and speaker enclosure portion 120 operate to form an audio enclosure. Chassis portion 100 can be, for example, a lower portion of a laptop computer chassis, or chassis portion 100 can be a back portion of a tablet chassis. An upper chassis portion or an upper chassis portion (not illustrated in FIG. 1A) can be connected with chassis portion 100 to provide an enclosure for an electrical system.
Edges 125 of speaker enclosure section 120 engage with, or meet with, an inner surface of chassis portion 100. Thus, inner surface 130 of speaker enclosure 120 becomes an inner surface of the resulting audio enclosure. Outer surface 160 of chassis portion 100 can include any features useful for the electronic device, for example, rubber feet, cooling features, etc.
FIG. 1B is a split side view illustration of the backside chassis portion and a partial speaker enclosure of FIG. 1A. FIG. 1B illustrates alignment between chassis portion 100 and speaker enclosure section 120, which form audio enclosure 150 when engaged.
FIG. 2A is a perspective-view illustration of an inner view of the backside chassis portion and partial speaker enclosure illustrating alignment. In FIG. 2A, line 190 indicates where edges 125 of speaker enclosure section 120 meet with chassis portion 100 to form audio enclosure 150 when speaker enclosure 120 and chassis portion 100 are connected. Inner surface 170 of chassis portion inside line 190 operates as the other “half” of the speaker enclosure made with speaker enclosure section 120. In traditional designs a complete box with a counterpart enclosure section would be placed within chassis portion 100, which would result in a less efficient system design.
FIG. 2B is a split side view illustration of the backside chassis portion and partial speaker enclosure of FIG. 2A. In one embodiment, chassis portion 100 can include edges, or lips, 105 for alignment with a counterpart chassis portion (not shown) and/or to provide edges or depth to the system enclosure. In one embodiment, edges 105 have holes to allow sound or heat to escape the system enclosure. In other embodiments, chassis portion and/or other chassis elements can have holes to allow sound and/or heat to escape.
In one embodiment, chassis portion 100 includes audio enclosure edges 155 for alignment with and/or placement of speaker enclosure section 120. In one embodiment, edges 125 of speaker enclosure section 120 fit within audio enclosure edges 155 and chassis portion edge 105.
FIG. 3A is a perspective-view illustration of the backside chassis portion and the partial speaker enclosure aligned and attached to form an audio enclosure. FIG. 3A illustrates chassis portion 100 engaged with speaker enclosure section 120. Various mechanisms can be utilized to hold chassis portion 100 and speaker enclosure section 120 together, for example, screws, clips, adhesive or any combination thereof. FIG. 3B is a split side view illustration of the backside chassis portion and the partial speaker enclosure aligned and attached to form the audio enclosure.
Audio enclosure 150 can be tuned in any manner known in the art. For example, the shape of various portions of chassis portion and/or speaker enclosure section 120 can be designed to give the desired audio performance.
FIG. 4 is a block diagram of one embodiment of an electronic system that can incorporate one or more speaker enclosures as described herein. The electronic system illustrated in FIG. 4 is intended to represent a range of electronic systems (either wired or wireless) including, for example, desktop computer systems, laptop computer systems, ULTRABOOKSTM, cellular telephones, personal digital assistants (PDAs) including cellular-enabled PDAs, set top boxes, tablets, etc. Alternative electronic systems may include more, fewer and/or different components.
