Abstract
The present invention proposes a voice device for a fire extinguisher. The voice device is installed on a fire extinguisher. The voice device comprises a power source, a control switch, a spring rocking switch, a capacitor, a voice IC, and a sound device. The spring rocking switch is connected to the power source. The voice IC is driven to output a specific signal when the spring rocking switch is on and electricity is conducted. The voice amplifying circuit receives the signal from the voice IC and outputs an amplified signal to the sound device for giving specific voices recorded in the voice IC. When the fire extinguisher is rocked, the voice device will automatically tell the user how to operate the fire extinguisher.
