Abstract

The embodiment of the invention provides an air broadcast alarm system which comprises a sound obtaining device which is used for obtaining an audio signal; an audio processing device which is connected with the sound acquisition device, wherein the audio processing device is used for carrying out audio processing on the audio signal to obtain a to-be-amplified audio signal; a power amplificationcircuit which is connected with the audio processing device, wherein the power amplification circuit is used for amplifying the to-be-amplified audio signal to obtain a to-be-played audio signal; a energy converter which is connected with the power amplification circuit, wherein the energy converter is used for playing an audio signal to be played; an electromagnetic compatibility filter which isconnected with the power amplification circuit, wherein the electromagnetic compatibility filter is used for suppressing interference electromagnetic signals generated in the operation process of theaircraft. By means of the technical scheme, the sound pressure level can be greatly increased, and therefore the on-site requirement can be met.

Description

technical field [0001] The present application relates to the technical field of broadcast equipment, in particular to an air broadcast warning system. Background technique [0002] At present, at the scene of an accident or other important occasions, a wired loudspeaker system or a hand-held voice loudspeaker etc. are used. [0003] However, due to the relatively low sound of wired speaker systems or handheld voice amplifiers, it is difficult to meet the needs of the scene. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide an air broadcast warning system to solve the problem that the prior art cannot meet the demand. [0005] The scheme of the embodiment of the present application is as follows: [0006] The embodiment of the present application discloses an air broadcast warning system, which is applied to an aircraft, and the air broadcast warning system includes: a sound acquisition device, the sound acquisitio...
