Application: Electronic device with speaker protection mechanism (Patent ID: US20240171908A1)
The patent filed by Acer Inc. describes an electronic device with a speaker protection mechanism that includes a speaker, amplifier circuit, level shift circuit, switch, and processor. The processor detects real-time characteristics of the adjusted output signal and provides an activation signal based on these characteristics to protect the speaker. The processor also controls the switch to transmit the output signal to the speaker for driving it. Additionally, the amplifier circuit adjusts the input signal to provide an output signal, and the level shift circuit adjusts the output signal to provide an adjusted output signal.
The electronic device's processor further includes a judging circuit to detect real-time characteristics of the adjusted output signal and output a first characteristic signal based on these characteristics. The switch control circuit then uses this first characteristic signal to enable or disable the switch based on predetermined ranges. The amplifier circuit also includes a detecting circuit to monitor the driving signal's characteristics and adjust the gain for amplifying the input signal accordingly. The level shift circuit adjusts the level of the output signal and blocks any direct-current component to provide an adjusted output signal with only an alternative-current component.
