Abstract

The invention relates to the technical field of sound box loudspeakers, and discloses a telescopic dustproof sound box loudspeaker. The telescopic dustproof sound box loudspeaker comprises a sound boxshell, a loudspeaker main body is fixedly connected to a lower surface in the sound box shell, a first telescopic pipe is movably connected in the sound box shell, and sliding slots are formed in both side faces in the sound box shell. The telescopic dustproof sound box loudspeaker is provided with the sound box shell, the first telescopic pipe and a second telescopic pipe, by changing the locations of the first telescopic pipe and the second telescopic pipe, the length of a sound transmission portion of the loudspeaker main body is telescopic, the heights of the first telescopic pipe and thesecond telescopic pipe are controlled by setting an insertion groove, an insertion rod, a screw and an extrusion block, the telescopic length can be adjusted, dust protection is performed on the loudspeaker main body by setting a dust cover, a first dust guard plate and a second dust guard plate, and by setting a first sound transmission hole and a second sound transmission hole, the dustproof effect of the loudspeaker main body is better, and the sound transmission is not affected.

Description

technical field [0001] The invention relates to the technical field of sound box speakers, in particular to a retractable dustproof sound box speaker. Background technique [0002] The horn is a very commonly used electroacoustic transducer. The speaker is the weakest device among electronic components, and it is the most important device for the speaker effect. Audio electric energy makes its paper cone or diaphragm vibrate the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. When the traditional speaker is not in use, because it does not have the dust-proof effect, it is easy to cause damage to the internal circuit due to the entry of dust, which affects the use effect and reduces the service life. The current speaker speaker is convenient to carry and does not take up space. Usually All of them are thin, short, and non-stretchable, so that the space of the speaker is sacrificed, so that the sound produced by the speaker c...
