DESCRIPTION OF EMBODIMENTS

[0026] In FIGS. 1 to 9 of the accompanying drawings there is an audio device 10. The device 10 has a base 11 that is intended to be fixed to a door 12 of a cabinet, such as the display cabinet of a supermarket. The cabinet may be a refrigerator or freezer. As an example, the base 11 could be attached to the door 12 by an adhesive pad.

[0027] Detachably secured to the base 11 is a module 13, with the module 13 including a hollow body 14 containing a printed circuit board 15 and a speaker 16.

[0028] The printed circuit board 15 includes an accelerometer 17, a de-bounce circuit 18 and an integrated circuit device (unit) 19 that can store a recorded message.

[0029] Movement of the door 12 is detected by the accelerometer 17. Upon detection of movement the accelerometer 17 activates the IC device 19 so that the speaker 16 is activated to deliver the recorded message stored in the device 17. Preferably the board 15 and speaker 16 are powered by a rechargeable battery 20.

[0030] Preferably, the module 13 can be reprogrammed to change the message contained in the device 17.

[0031] Preferably, the body 14 is removably attached to the base 11 by resilient clips 21 that resiliently deform to provide for attachment and detachment of the module 13 with respect to the base 11.

[0032] The module 13 is recharged by being placed in a pad 22 that may receive one or more of the modules 13. The module 13 includes a manually operable switch 22.

[0033] In the embodiment of FIGS. 10 to 13, body 14 is provided with resilient catch members 30 that resiliently deform and are urged into engagement in apertures 31 of the base 11 to secure the body 14 to the base 11.

[0034] Further in respect of this embodiment, the body 14 receives a removable/rechargeable battery 20.

[0035] In a further embodiment, the printed circuit board 15 would be provided by means enabling the board 15 to communicate wirelessly with a controller. As a particular example board 15 could receive signals for programming the integrated circuit device 19, such as to receive a new recorded message. In a further embodiment, the board 15 could be adapted to send wireless signals for the purposes of providing the controller with information. More specifically the board 15 would include a wireless communication device 32.

[0036] Preferably the speaker 16 is a polyphonic speaker.

[0037] The above described preferred embodiments provide a number of advantages, including being able to program the module 13 to deliver advertising via the speaker 16, when the door 12 is opened.
