| 摘要 |
<p>The present invention relates to a sound and rotating apparatus capable of emitting light via airflow. A sound apparatus capable of emitting light via air flow comprises a body (120) including an air inlet (110) arranged at one side thereof, an air outlet (150) arranged at the other side thereof to communicate with the air inlet and a sound generating unit arranged between the air inlet and the air outlet; electric generating means (100) arranged within the body (120) for turning a fan via inflow and outflow air to generate electricity; and a luminous element (160) for emitting light by means of electricity generated from the electric generating means (100). A rotating apparatus capable of emitting light via air flow comprises an electric generating unit (26) for turning rotary blades (28) via air introduced or exhausted with the air motor to generate electricity; and a luminous element (30) for emitting light to a point where the machining tip (25) performs a rotation operation. The invention can generate electricity by itself instead of using disposable batteries to simplify a construction thereof thereby saving fabrication cost as well as to enhance the efficiency of operation thereby enabling a precise operation to be performed.</p> |
