We have covered a number of quality speakers for iPhone in the past. Not all of them are portable or cheap though. The TDK TAC3122N speaker system happens to be one of the most portable iPhone speakers around. It has a foldable design and comes equipped with a Lightning dock connector.
The TDK TAC3122N speaker has a 50mm passive radiator and two 40mm full-range speakers. It can charge and play your phone. You can power it using an AC adapter or 4 AAA batteries (they will last you up to 6 hours). The device will start shipping in September. Looks quite decent for what it is.[via]
