Ditch normal speakers for audio exciters

We all know that most laptop speakers are not the best, bass is often lacking, mids are weak and they sound rather "tinny".

Since laptops have a very limited space, large speakers are not a option.  But there is hope.  The "exciter" is a speaker like no other.  Instead of using a cone to produce sound, it sticks to a flat surface and vibrates the surface.  These speakers are very thin, small and light weight.

So, you could install 2 small tweeters, then install a pair of these "exciters" into the LCD case, or the palm rest, or even the bottom cover.  Thus turning the whole laptop chassis into the speaker.

Here is a company that sells them, they also have specs and info on them.

    Yes, but generally they can pause and move the drive head out of the way when they detect significant movement. With an audio exciter, significant vibrations would be caused throughout the chassis and a hard disk is extremely susceptible to vibration, especially when it is active, which it will likely be when the system's speakers are used (to access music, play the game, movie, etc.)

    Salanos, you could install them in the back panel of the LCD screen, this would create a "speaker" the same size as the plastic cover on the back of the lcd.

    It would also remove most of the risk of vibration on the hdd.  But, laptop hdds are pretty robust seeing as they are installed in a computer  that constantly moves about.

    While, as an audiophile, I find this idea intriguing, I think it highly impractical for a notebook as well. It'd be fine for ultrabooks or, rather, any notebook containing a SSD exclusively, but for a notebook running a spinning mechanical hard drive, you're looking at hard-drive-failure fuel here.

    Yes, I was really impressed by a USB vibro speaker that I gave away as a present. It saved the party as the speakers on the HP laptop were too low, bot regarding volume and quality :)

    I think even if dell installed a single one into the lcd back it would make a huge impact in bass response.  After hearing my friends exciter on a table, I see there being a huge advantage for them in a laptop setting.

    Very interesting. I didn't know they could produce so compact vibro speakers.
    Maybe if DELL could test them with a prototype laptop to see if they are good enough for a premium sound experience?
