Designing the Logitech Rechargeable Speaker S315i

After the Logitech Rechargeable Speaker S315i won the prestigious iF Design Award 2010 in December, you may recall that I said to “stay tuned” for information from our design team on how we brought the Logitech Rechargeable Speaker S315i from paper to final product. Below is a brief interview with Eugene Canavan of Design Partners – the design agency that I worked closely with during the design and development of the Logitech S315i – about his experience working with us to develop this award-winning product.

“We wanted to create an expressive but simple shape that people could easily slip into their bag and that would be robust enough to protect the docking connector during travel. We found from experimentation with models that the foot could fold inwards to do this job very well – it’s always great with travel products when you can get one part to do two jobs, this saves space and weight.

Keeping the front of the speaker dock as simple and as uncluttered as possible meant we were able to let the iPod, and by extension your music, remain centre stage and the focal point of the performance.

We decided on a slightly rounded form for the body. This helped express the expansive character of sound and music – something like a musical instrument or like a singers lungs filling with air. This shape also helped us to successfully contain the right volume of air needed for acoustic purposes – resulting in big volume compressed into a small portable shape!” – Eugene Canavan, Designer,

  • hello Doug, could you explain the buttons on top of the s315i there is three position, one is “off” the middle one which plays the music and the “X2” which also plays the music ?

    • Hi MikeR,

      This setting is a power saving mode that will extend the battery life for up to 20 hours.


  • Doug,
    Congrats on what I think is the greatest all around designed speaker systems available right now. Really great work.
    I also collect second hand apple ipod hi-fi’s and place them around the house via wi-fi air-tunes (the other beautifully minimalist designed speaker out there). But I would like to make you aware of a thread on the logitec forums “S315i speaker powering down”.
    Any insight into the issue?
    I feel bad, I just, kinda did a little ball busting on the R and D due to this issue in the thread, and then I ran across you blog. I’m a design nut and super picky about the tech I buy. I could not be happier about my purchase except that I have to switch the power button back on every 15 to 30 minutes. Was the system not tested for streaming apps on the touch and iphone OS?
    Sincerely, Jim
