Dell Inspiron 8200 internal speaker has stopped working for more than a year now. I however get sound when connecting the headphones to the audio out port. The solution I found out was the motherboard needs to be replaced; which I reckon is an expensive option for a six year old notebook.
Whilst on my flight to India (in KLM's inflight magazine) I came across this tiny speaker manufactured by Lifetrons of Switzerland. The product is the world’s first extendable vacuum bass speaker, utilizing the patented Bass Xpansion System™ (BXS) technology which was developed and powered by Singaporean based technology company XMI. It costed me 30 Euros, saving me an expensive motherboard replacement. I am certainly impressed with the quality of the speakers.
