We need to find the standardized contacts for: audio input left channel, right channel, and ground. (Wikipedia reference: Phone connector (audio) ).What was once an expensive luxury is now widely accessible thanks to a prolific landscape of manufacturers mass producing speakers to fit every taste and budget.Some have even become branded promotional giveaway items.
As a consequence, nowadays its not unusual to have a small collection of them, a fertile field for hacking. Our main obstacle is a side effect of market diversity: with so many different speakers, a hack posted for one speaker wouldnt apply to another. Cadillac Cue System Hacks Bluetooth Audio ModulesIt doesnt help that most Bluetooth audio modules are opaque, their development toolchains difficult to obtain. Lets throw the Bluetooth overboard but embrace all those other things. Now hacking these boxes just requires a change of mindset and a little detective work. Cadillac Cue System Hacks How To Drop AnIll show you how to drop an Arduino into a cheap speaker as the blueprint for your own audio adventures. But by changing our Bluetooth speaker mindset from its a reprogrammable computer to its an integrated collection of useful electronic components, we turn market diversity into our ally. Surprising the customer with big sound from a little box is key for success, so each product can offer a unique combination for driving the audio, all housed inside an eye-catching enclosure that lets consumers tell one portable Bluetooth speaker from another. Catering to these desires, components are excluded from the tightly integrated mystery black boxes. Fortunately for hardware hackers, such an architecture also makes components easy to reuse. But before we begin, an obligatory note in case it is not obvious to any beginners reading this: This activity very definitely voids the warranty (do it, its worth it), and modern portable electronics use lithium chemistry batteries that can be dangerous if mistreated. The rugged claim starts with a layer of soft rubber wrapped around its exterior. Cadillac Cue System Hacks Plus Reinforcements InsideThat plus reinforcements inside the case allows the speaker to absorb some level of abuse. I wanted to preserve this shock absorbing exterior and, thankfully, it was easy to open non-destructively. Alternatively, if the plan is to transfer the internals to another enclosure, the condition of the original box would not matter. A search for ATS2823 confirmed it is a module designed and sold for integration into Bluetooth audio products. Its MIPS M4K core and associated flash storage could be a promising start for firmware hacking, but the point of this example is to demonstrate how to hack a speaker utilizing existing firmware. We want the system to believe we are connected via an audio cable plugged into the line-in jack, but for compactness wed prefer to do this without using an actual cord. This approach is easy, nondestructive, and preserves the existing volume control mechanism. There are a lot of different ways to implement an audio jack, so some exploration with a multimeter will be required.
