ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a writing instrument, and more particularly to an interesting pen that can make sounds and emit light.
2. Description of Related Art
A writing instrument is a necessary tool for a person. However, conventional writing instruments are not attractive to children because of their monotonous appearances. Thus, a writing instrument with an illumination function was invented for children, and the children welcomed it with much interest. Nevertheless, the writing instrument with only an illumination function will soon lose its appeal to children.
Therefore, an objective of the present invention is to provide a writing instrument not only with an illumination function but also a sound function to mitigate and/or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a writing instrument that can emit light and sound.
Another objective of the invention is to provide a writing instrument in which the sound function can be enabled or disabled by the user.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
