US 2017/0249023 A1 · SOUND CONTROLLED LIGHT PEN

Abstract

A sound controlled light pen includes a main body and a sound controlled light emitting structure. The main body includes a pen barrel and a cartridge installed in the pen barrel. The sound controlled light emitting structure is connected to the pen barrel and includes a casing with a transparent portion, a transparent film covered onto the transparent portion, a microphone, a light emitting element, and a controller. The casing A further contains a circuit board provided for installing and electrically connecting the microphone that senses a change of sound and generates a sense signal, the light emitting element that is configured to be corresponsive to the transparent portion, and the controller that controls the light emitting element to emit light after receiving the controller sense signal, so that the sound controlled light pen and the sound controlled light emitting structure have excellent interactions with each other.
