## Background
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The invention relates to a driving device, and particularly to a driving device for handicraft with acousto-optic control and driven by batteries.
2. Description of Related Arts
Conventional driving devices for handicrafts that are on the market, especially driving devices for optical-fiber handicraft generally utilize a motor to drive a rotary plate to revolve so as to produce dynamic visual effects. Driving devices as such are only capable of performing one single function, monotonous in shape, and, as such driving devices are for driving the driving groove to revolve through driving lever, their power consumptions tend to be large, and therefore require external power such as adapters because such driving devices cannot be driven by batteries, which are inconvenient to carry around.
At the same time, as the on/off of conventional optical-fiber handicrafts can only be controlled by a lever switch, operation is inconvenient. In addition, as the multi-color light effect of conventional optical-fiber handicraft is created by passing light through colored films, the quality of the color created is poor. As a result, the convention technology of driving devices for conventional handicraft has to be improved to satisfy growing expectations of consumers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 and FIG. 4 of the drawings, a driving device with asousto-optic control and driven by batteries according to a preferred embodiment of the present invention is illustrated, wherein the driving device comprises a base 1, wherein a battery compartment 2 is defined therewithin. Together with a cover 3, the battery compartment 2 is adapted for inserting batteries.
The base 1 further comprises a three-positional switch 4, a power connector 5 for an external power adaptor, wherein the three-positional switch 4 is connected both to a battery inside the battery compartment 2 and the power connector 5 for an external power source, a circuit board 6 connected to the three-positional switch 4, a speaker 7 connected to the circuit board 6, a motor 8 having a rotating axis, wherein the motor 8 is secured and a circuit boards 9 for controlling two groups of small lamps located at the upper inner surface of the base 1.
When the power connector 5 is connected with an external power source or when batteries are inserted and when the three-positional switch 4 is in an off position, power will not be connected therefore no components will work. When the three-positional switch 4 is in a first on position, the rotating axis of motor 8 will start turning.
A small belt pulley 22 on the same rotating axis is in connection a large belt pulley 10 through a belt. A small gear 11 is associated with a large gear 12, wherein the small gear 11 is secured on the same axis as the large belt pulley 10. A second small gear 13 is secured on the axis as the large gear 12.
Through combinations of such gears, the rotational speed of the motor 8 at rotating axis 14 is finally reduced to a device rotational speed require by the device. The rotating axis 14 extends to the surface of the base 1. An edge of a round rotating plate 15 is securely connected to the rotating axis 14, so that as the rotating axis 14 rotates, the round rotating plate 15 performs circumferential movement with the rotating axis 14 as the center and with its own diameter as radius. A frame 16 has an inner frame hole, wherein the rotating plate 15 is located therewithin. The width of the frame 16 equals to the diameter of the round rotating plate 15 while the length of the frame is twice as long as the distance defined by the rotating axis 14 and an opposite edge of the round rotating plate 15.
A strip structure 17 extends from a side of the frame 16, wherein a strip structure base of the strip structure 17 is sits in a sliding groove 18 so that when the round rotating plate 15 rotates, the frame 16 will be driven to make a linear movement and that in turns results in the corresponding linear movement of the strip-shaped structure 17 in the sliding groove 18.
Two holes 19 are defined besides each side of the sliding groove 18 respectively, wherein each of the two holes 19 goes through the base 1, and facing directly to two circuit boards 9 respectively, wherein each of the circuit boards 9 controls the two groups of the small lamps inside the base 1 respectively.
Each of the group of small lamps contains three small lamps of three different colors of red, green and blue. Two pipes 20 are extending from each of the holes 19 respectively, wherein on a rim of each of the two pipes 20 is a pipe rim teeth structure, forming a gear, each of which matches with a strip teeth structure on each side of the strip structure 17 respectively, so that when the strip structure 17 slides forwardly and backwardly on sliding groove 18, the two pipes 20 revolves clockwise and anti-clockwise alternatively.
At a pipe top of each of the pipes 20, a securing structure 21 is secured to the base 1 with screws respectively, wherein the securing structure 21 has two securing holes 22 defined therewithin, wherein the two securing holes are located aligningly with the two pipes 20 respectively to hold the pipes in place. A securing structure sliding groove is also aligned to the sliding groove 18 so that the strip structure 17 will slides in the two grooves securely.
Consequently, when the power connector 5 is connected to the external power source and the switch 4 is turned on, the circuit boards 9 controlling the two groups of small lamps will connect power to the circuit and the small lamps of different colors flash alternately. The light produced from the lamps passes through the holes 19 and pipes 20 and thus into the handicrafts fixed in the pipes 20.
In one preferred embodiment, optical-fiber beams are fixed in the pipes 20 and arranged into a radiating form of a wing. The light passing through the optical-fiber will have colorful effect of three colors changing alternately. At the same time, as the motor 8 drives the rotating axis 14 to rotate via a series of driving devices and the two pipes 20 to revolve clockwise and anti-clockwise alternatively via the said driving devices, the wing-shaped optical-fiber handicrafts fixed in the two pipes 20 will also revolve, making the wing flap and producing dynamic effect of changing colors that have very strong ornamental effect.
According to the preferred embodiment, the circuit board 6 inside the base 1 further comprises a timer circuit and an inductive circuit. The timer circuit automatically cuts off power after a certain period of time of power connection while the inductive circuit is capable of inducting to change of light and sound so that when light is turned on or off suddenly, or noise pattern changes suddenly such as air vibration caused by hand-clapping or loud speaking voice, the circuit will be initiated at once to generate lighting effect. After a certain period of time, the timer circuit will automatically turn off the device. Consequently, the present invention can produce a surprising decorative result.
When the three-positional switch 4 is in a second on position, the circuit will connect to another circuit that produces sound with the speaker 7 playing electronic music to accompany the change of colors and revolving movement to enhance the accessorizing art effect. After a certain period of time, the device will stop automatically in the same way to be initiated again by the next sound or light change.
