Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker dust cleaning device. Background Art

[0002] A loudspeaker, also known as a horn, is a very commonly used electroacoustic transducer device that can be found in any sound-generating electronic or electrical device. A loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of a loudspeaker has a great impact on the sound quality. The loudspeaker is the weakest component in an audio device, but it is also the most important component for sound effects. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, resonating (resonating) with the surrounding air to produce sound. When inspecting and servicing a loudspeaker, it is necessary to clean the dust from it.

[0003] A Chinese utility model patent, publication number CN 205673238 U, discloses a loudspeaker dust cleaning device comprising a base, a slide rail II, a servo motor, a left bearing seat, a screw, a nut, a right bearing seat, a support rod, a spring I, a cylinder, a slider I, a slide rail I, a pressure plate I, a rag, a loudspeaker, a connecting rod I, an electromagnet, a slider II, a spring II, a rotating rod, a rotary motor, an iron block, a slider III, a connecting rod II, an electric wheel, a pull wire, and a pressure plate II. The top of the base is provided with, from left to right, a rotary motor, a servo motor, a left bearing seat, and a right bearing seat. This device achieves clean, easy-to-operate, and fast cleaning results, allowing for rapid cleaning of loudspeakers. The inventors believe that the following drawbacks exist in the aforementioned related art: Clamping the loudspeaker requires a worker to hold the device for a long time, waiting for the clamping device to tighten before releasing it, increasing the worker's workload. Furthermore, using a blower to remove dust from the loudspeaker does not completely remove the dust, hindering subsequent cleaning of the loudspeaker. Utility Model Content
