Title: Safety Protection System for Speakers
Inventor: KIM DONG IL
IPC: H02H3/18
Filed: 2019-09-25
Abstract: The present invention relates to a safety protection system for a speaker. A speaker system includes a plurality of speakers electrically connected to an amplifier through wires to receive voltage from the amplifier and output sound; and a forward diode formed in the speaker to block a reverse current when an overvoltage occurs to prevent damage to the amplifier or the speaker due to the reverse current. When an overvoltage occurs on the wire connecting the amplifier and the speaker due to an accident such as a fire or a short circuit, it is possible to prevent the overvoltage from flowing in the reverse direction through the forward diode formed in the speaker. Accordingly, it is possible to minimize damage to the amplifier and speaker due to overvoltage, and transmit an evacuation announcement to people using the building through the speaker for a long time, so that the loss of life from a safety accident can be minimized. By compensating the voltage drop due to the forward diode installed in the speaker in the power amplifier, it is possible to compensate for smooth sound output through the speaker. The noise that may be generated due to the voltage amplification of the power amplifier is removed through the noise attenuator, thereby inducing a clear and stable output through the speaker to ensure the safety of the device.
