Abstract

A USB flash memory device is provided which, when inserted into a USB port of a personal computer, automatically connects to a remote central management system via a wide area network such as the Internet to download updated audio and plays recorded audio. The housing of the memory device may be imprinted with promotional information. The recorded audio may include a promotional message, a message relating to a sweepstakes or other contest or any other information. The memory device includes a sound chip which includes its own memory that stores the recorded message. The sound chip of the memory device may be pre-recorded in mass with an initial message. Power to the memory device is supplied by the personal computer. The central management system stores and provides updated audio content for the flash memory device, and stores statistical data concerning use of the flash memory device.

Claims

1. A portable data storage device, comprising:

a connective port electrically connectable to a host machine, whereby the host machine provides power to the portable data storage device;

a non-volatile memory unit;

a memory controller for controlling the transfer of data between the non-volatile memory and the host machine via the connective port;

a sound transducer;

a sound unit for storing recorded audio content and playing the stored audio content through the sound transducer when the connective port is connected to the host machine; and

interface software stored in the non-volatile memory unit for automatically connecting the host machine to a remote server, receiving updated audio content from the remote server, and providing the updated audio content to the sound unit.

2. The portable data storage device of claim 1 wherein the connective port is a USB port.

3. The portable data storage device of claim 1 wherein the non-volatile memory comprises flash memory.

4. The portable data storage device of claim 1 wherein the audio content comprises a promotional message.

5. The portable data storage device of claim 1 wherein the audio content comprises a message related to a sweepstakes or contest.

6. The portable data storage device of claim 1 wherein the updated content comprises an instruction to the sound unit to play a particular pre-recorded audio file.

7. The portable data storage device of claim 1 wherein the non-volatile memory is partitioned into a secure portion and a non-secure portion, the interface software being stored in the secure portion.

8. The portable data storage device of claim 1 wherein the sound unit comprises an analog audio input, an A/D converter for converting analog signals from the analog audio input to digital form, memory for storing the digitized audio, a D/A converter for converting the stored digitized audio to an analog signal, an amplifier for amplifying the analog signal from the D/A converter, and an audio output for outputting the amplified analog signal to the sound transducer.

9. The portable data storage device of claim 1 further comprising user-activated means for disabling playing the audio content.

10. A system for dynamically updating audio content stored in portable data storage devices, comprising:

a central management system comprising a database,

a plurality of portable data storage devices, each portable data storage device comprising a connective port being electrically connectable to a host machine, a non-volatile memory unit, a memory controller for controlling the transfer of data between the non-volatile memory and the host machine via the connective port, a loudspeaker, a sound unit for storing recorded audio content and playing the stored audio content through the speaker when the port is connected to the host machine, and interface software stored in the non-volatile memory unit for automatically connecting the host machine to the central management system, receiving updated audio content from the central management system, and storing the updated audio content in the sound unit.

11. The system of claim 10 wherein the host machine connects to the central management system via the Internet.

12. The system of claim 11 wherein the central management system comprises a server, an IP address uniquely identifying the server is stored in the non-volatile memory of the portable data storage devices, and the interface software uses the IP address to connect to the server.

13. The system of claim 10 wherein the audio content comprises a promotional message.

14. The system of claim 10 wherein the central management system comprises database management software which searches the database for updated audio content associated with the portable data storage device.

15. The system of claim 10 wherein the database stores statistical data associated with the portable storage device.

16. A method for dynamically updating and automatically playing audio content from a portable data storage device, comprising:

providing a portable data storage device having a connective port electrically connectable to a host machine whereby the host machine provides power to the portable data storage device, a non-volatile memory unit, a memory controller for controlling the transfer of data between the non-volatile memory and the host machine via the connective port, a sound transducer, and a sound unit;

storing audio content in the sound unit;

automatically connecting the host machine to a remote server, receiving updated audio content from the remote server, and storing the updated audio content in the sound unit, and

automatically playing the audio content from the sound unit through the sound transducer.

17. The method of claim 16 wherein the connective port is a USB connector.

18. The method of claim 16 wherein the non-volatile memory unit comprises flash memory.

19. The method of claim 16 wherein the audio content comprises a promotional message.

20. The method of claim 16 wherein the audio content comprises a message related to a sweepstakes or contest.
