Toucan Bluetooth Speaker Teardown

Goal: Teardown the Toucan Bluetooth Speaker to find out what is inside, and particularly, can I fit a RaspberryPi inside it?

The Toucan Bluetooth Speaker is a ubiquitous promotional product. It is availabe from a large number of vendors, who customize it with your desired brand. A web search will find many potential sources.

Superficial examination

Functions

The Toucan is a remote amplified speaker. Connection to a music source is offered by way of a 1/8" line-in jack, by Bluetooth pairing, or by NFC pairing. The device is switched on and off by way of a sliding switch on the rear panel. Three buttons on the front panel control volume, and pairing.

Opening the device

The case is plastic, with a metal audio grill, and molded rubber-like feet.

The device has no visible fasteners. The battery compartment is clearly marked and yet inscrutable. A sticker provides a dire warning about battery danger. The front and rear decorative cover plates are the majority of the device branding customization. They are attached by adhesive and cover the access panel retaining screws.

Tools

  • small prying tool such as a backup 3mm slot screwdriver
  • #1 Phillips screwdriver
  • solvent
  • towels or rags
  • thin packing tape

Remove rear cover plate

The rear cover plate blocks access to the rear access panel. The rear access panel provides access to the circuit board and speaker cabinets.

Remove the rear cover plate by lifting gently from the adhesive tape that secures it to the device. The pernicious adhesive tape is both gooey and fibrous. The tape resists alcohol-based solvent, but citrus turpene / petroleum distilate solvent loosened the grip enough for mechanical removal by patient, gentle scraping.

The decorative power switch cover is held in position by the rear cover plate. Retain the decorative power switch cover when the rear cover plate is removed. The decorative power switch cover is not rotationally symmetrical. If re-assembly is awkward, check that the decorative power switch cover is correctly oriented.

Open the rear access panel

The rear access panel is fastened by ten retaining screws, including two of the retaining screws for the lower access panel. Remove the ten retaining screws. The rear access panel should open easily once the screws are removed. If the upper portion of the access panel appears stuck, it may be further fastened by some of the adhesive from the metal mesh acoustic surround. Pry gently and hope for the best.

Product RFID tag

An RFID tag was found on the inside of the rear access cover. This RFID tag may have been used in manufacturing and cusomization of the device. No documentation for the RFID tag accompanied the device.

Inside the Toucan Bluetooth Speaker

Opening the rear access panel reveals separate compartments for the left speaker cabinet, the circuit board and the right speaker cabinet.

Each speaker cabinet contains a driver and a passive radiator.

Answer: No.

While there appears to be space for a RaspberryPi within the Toucan, that space includes the speaker cabinet walls. So, no easy conversion to RaspberryPi in this one.

Optionally, open lower access panel

Two additional steps are required to open the lower access panel. The lower access panel provides access to the battery compartment.

Remove front cover plate

The front cover plate blocks access to half of the retaining screws for the lower access panel. The same pernicious, gooey, fibrous tape holds the front cover plate in place. Pry the front cover plate from the adhsive tape.

Remove lower access panel retaining screws

The lower access panel is fastened by the two lower retaining screws on each of the front and back of the device. Remove the four battery cover screws and gently open the lower access panel. Two wires connect the battery compartment to the main circuit board and limit the removal of the lower access panel.

The lower access panel reveals two passive radiators, a portion of the circuit board and the battery compartment.

Reassembly

The Toucan was reassembled in approximately the reverse order. Reverse loops of packing tape served to replace the adhesive tape originally used to hold the cover plates to the access panels. Mind the orientation of the power switch.

Have fun.

Finally

The sound quality is fair. The automated voice announcements from this device, "Power. On." and "Power. Off." have been startling to the unprepared. Those same announcements have proven instructive when evaluating the snoopiness of guests. I find the blinking status LED to be distracting, so a bit of electrical tape is in order.
