General aircraft loudspeaker with sound amplifying function

Abstract

The invention discloses a general aircraft loudspeaker with a sound amplifying function. The general aircraft loudspeaker comprises a sound amplifying shell, the sound amplifying shell is movably installed in an installation cavity of an interior shell of an aircraft, a panel is fixedly installed at the front end of the sound amplifying shell, a layer of protective net is fixedly installed at thecenter position of the front end face of the panel, limiting clamping heads are movably arranged on the upper side and the lower side of the panel correspondingly, the upper end of the sound amplifying shell is fixedly provided with a movable rack, and the upper end of the movable rack is meshed with a first transmission gear through gear teeth. According to the general aircraft loudspeaker with the sound amplifying function, the movable telescopic sound amplifying shell is designed, an external loudspeaker is installed in the sound amplifying shell, sound amplifying is achieved, the rack andthe gear are designed at the upper end of the sound amplifying shell to control the expansion and contraction of the sound amplifying shell, and meanwhile, the limiting clamping heads are arranged onthe panel at the front end of the sound amplifying shell to fix the sound amplifying shell, so that vibration of the aircraft during take-off and landing can not affect the sound amplifying shell.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a general-purpose aircraft loudspeaker with sound amplification function. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals. It is mainly composed of magnets, frames, centering supports, and molded ring cones. It is an important component in audio and broadcasting systems. The loudspeaker is based on the principle And structures can be divided into many types, which are widely used in all walks of life. In the broadcasting system and sound system in the aircraft, speakers are also needed for broadcasting and playing video music. However, for the sake of beauty, the aircraft The internal broadcast system and sound system are embedded in the shell of the interior layer and kept flush with the interior surface.

[0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals. It is mainly composed of magnets, frames, centering supports, and molded ring cones. It is an important component in audio and broadcasting systems. The loudspeaker is based on the principle And structures can be divided into many types, which are widely used in all walks of life. In the broadcasting system and sound system in the aircraft, speakers are also needed for broadcasting and playing video music. However, for the sake of beauty, the aircraft The internal broadcast system and sound system are embedded in the shell of the interior layer and kept flush with the interior surface. In this case, when the speaker is working, most of the sound waves are transmitted into the interior layer, and in the Resonance occurs in the interior layer, which causes the sound played by the speaker to be dull and ambiguous, which affects people's accurate hearing of the content broadcast by the speaker, thereby affecting the normal operation of the broadcasting system and the sound system
