Abstract

A USB flash memory device is provided which automatically plays pre-recorded audio when the device is inserted into a USB port of a personal computer. The housing of the memory device may be imprinted with promotional information. The pre-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 pre-recorded message. The sound chip of the memory device may be pre-recorded in mass, or optionally an end-user may record its own personal message. Power to the memory device is supplied by the personal computer.

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; and

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.

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 sound transducer is a loudspeaker.

7. The portable data storage device of claim 1 wherein the sound transducer functions both as a speaker for playing the audio content from the sound unit and a microphone for recording audio content to the sound unit.

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 portable data storage device, comprising:

a housing;

a circuit board mounted inside the housing;

a connective port connected to the circuit board and extending from the housing, the port being electrically connectable to a host machine, whereby the host machine provides power to the portable data storage device;

a non-volatile memory unit mounted on the circuit board;

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

a loudspeaker; and

a sound unit mounted on the circuit board for storing recorded audio content and playing the stored audio content through the speaker when the port is connected to the host machine.

11. The portable data storage device of claim 10 wherein the port is a USB port.

12. The portable data storage device of claim 10 wherein the non-volatile memory comprises flash memory.

13. The portable data storage device of claim 10 wherein the audio content comprises a promotional message.

14. The portable data storage device of claim 10 wherein the audio content comprises a message related to a sweepstakes or contest.

15. The portable data storage device of claim 10 further comprising an LED which is illuminated when data is being transferred between the portable data storage device and the host machine.

16. A method for 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; and

automatically playing the audio content from the sound unit through the sound transducer when the connective port is connected to the host machine.

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.
