Decoration device with projection images for holidays, festivals and parties

1. A decoration device with projection images for holidays, festivals and parties, the device comprising:

(a) a shell;

(b) a module provided inside the shell, the module being provided with a power source;

(c) a projection unit mounted on the module;

(d) a projection film provided on the projection unit;

(e) an LED light source disposed at one side of the projection film so that an image formed on the projection film can be projected on a surface of the shell by the light source when turned on by the power source;

(f) a Bluetooth® speaker mounted inside the module, wherein Bluetooth® technology is used for communication between the speaker and a mobile device so that the speaker can play music and sound from the mobile device; and

(g) a separate projection unit mounted on an outer surface of the shell for projecting a separate image on a wall, wherein the separate projection unit comprises a separate LED light source and a separate projection film formed with the separate image.

2. A decoration device with projection images, the device comprising:

(a) a shell;

(b) a module provided inside the shell, the module being provided with a power source;

(c) a projection unit mounted on the module;

(d) a projection film provided on the projection unit; and

(e) a light source disposed at one side the projection film so that an image on the projection film can be projected on a surface of the shell by the light source when turned on by the power source;

wherein the projection unit is cylindrical in shape, a 4-sided film holder is provided inside the cylindrical projection unit for holding thereon four projection films with four images respectively, and a rectangular opening is formed on the cylindrical projection unit to allow projection of the image on one of the four projection films.

3. The device as claimed in claim 2 , wherein the projection unit is dome-shaped.

4. The device as claimed in claim 2 , wherein the projection film is cylindrical in shape.

5. The device as claimed in claim 4 , wherein the cylindrical projection film is supported on a first shaft coupled with a first gear which is meshed with a second gear, and the second gear is coupled with a second shaft rotatable by a switch formed at one end thereof, whereby the cylindrical projection film is rotatable by turning the switch.

6. The device as claimed in claim 2 , wherein the image on the projection film is selected from the group consisting of transparent image, non-transparent image, cut-out hole and silhouette.

7. The device as claimed in claim 2 , wherein the projection unit is hingedly connected with the module by a hinge mechanism so that projection angle can be adjusted.

8. The device as claimed in claim 7 , wherein the hinge mechanism comprises two hinge rods formed on the projection unit and frictionally engaged within two c-shaped openings formed on two hinge rod-holding stands provided on the module respectively.

9. The device as claimed in claim 2 , further comprising a speaker mounted inside the module.

10. The device as claimed in claim 9 , wherein the speaker is a Bluetooth® speaker and Bluetooth® technology is used for communication between the speaker and a mobile device so that the speaker can play music and sound from the mobile device.

11. The device as claimed in claim 9 , further comprising an integrated circuit chip connected with the speaker to playback pre-recorded music and sound stored in the chip.

12. The device as claimed in claim 2 , further comprising a battery compartment provided in the module for holding therein a battery for supplying electric power.

13. The device as claimed in claim 2 , further comprising a micro USB port provided on the module for connection with a charger for charging a rechargeable battery provided in the module.

14. The device as claimed in claim 2 , wherein the light source is an LED light source.

15. The device as claimed in claim 2 , further comprising a separate projection unit mounted on an outer surface of the shell for projecting a separate image on a surface facing the separate projection unit.

16. The device as claimed in claim 15 , wherein the separate projection unit comprises a separate light source and a separate projection film formed with the separate image.

17. The device as claimed in claim 15 , wherein the separate projection unit is dome-shaped.

18. The device as claimed in claim 2 , wherein the four-sided film holder comprises a central shaft with a 4-tooth gear mounted on a lower end thereof, and a shaft connector provided with a pointy tooth engageable with the 4-tooth gear so that when a button provided on the shaft connector is pressed in a direction towards a biasing spring mounted on a rod connected to one side of the shaft connector opposite to the button, the pointy tooth engages with the 4-tooth gear and rotates the 4-tooth gear as well as the four-sided film holder forty-five degrees, and when the button is released the shaft connector returns to its original position under the biasing force of the spring.
