FIELD OF THE INVENTION
This invention relates generally to speaker systems, and relates, more particularly, to portable speaker apparatuses and related methods.
BACKGROUND
The portable audio market has changed dramatically in the past several years. Recent trends have focused on the improvement of overall sound quality of portable devices. Much of the improvement has occurred in the sources for sound generation. For example, portable CD audio players and MP3 audio players have garnered increasing shares of the portable market in comparison to more conventional cassette players and radio sources. While focus on such sources has helped the overall perceived sound quality, further improvements have been somewhat limited by portability constraints.
Portable audio products find wide usage in society. These audio products are often employed for work and personal use, e.g., at the office or home, as well as during travel in the car, in a park, garage, or hotel room, or even in business presentations using a laptop computer. The required portability of these audio devices limits the overall size and weight of the system and hence the types and sizes of the speaker drivers and enclosures used. Some conventional portable audio products include self-contained units such as portable radios and boomboxes to address the portability needs whereas others employ headphones, built-in laptop computer speakers, and miniature amplified speakers to accommodate portability in sound producing means.
Generally, it can be desirable from a practical use standpoint to not have to use headphones or ear buds thereby allowing the listening of content playing on the portable device and still hearing ambient sounds. Unfortunately, self-contained conventional portable audio products, such as the aforementioned portable radio and boomboxes, do not provide flexibility of use, tend to consume large amount of space proportional to their quality of output signal and typically have limited or no positional flexibility or adjustability. In other words, if a user desires to take her music with her and not limit her ambient hearing, she is likely limited to carrying a portable radio or boombox. Consequently, there is a trade-off between portability and usability.
Therefore, a need exists in the art to develop portable and usable apparatuses and related methods that address such limitations of the current technology.

The first speaker housing in combination with the first speaker element can be the same as or similar to speaker 133 (FIGS. 1-4, 9-23), speaker 135 (FIGS. 1-4, 9-23), or speaker 2435 (FIGS. 24-29). It should be noted that the order of processes 3010 and 3020 can be reversed, or process 3010 and process 3020 can be performed at the same time.
Method 3000 continues with a process 3030 of coupling the first speaker housing to the first end of the first flexible member. As an example, FIGS. 1-4 and 9-23 show flexible member 131 coupled to speaker 135, and FIGS. 24-29 show flexible member 2431 coupled to speaker 2135.
