Description

Technical Field

[0001] The utility model relates to the technical field of audio collection, in particular to an audio collection and external playback device. Background Art

[0002] In the digital media age, audio capture has become an integral part of many fields, including music production, filmmaking, podcasting, and voice recognition. Audio capture is the process of converting sound signals into digital signals for easy storage, editing, and transmission. After capture, audio often needs to be played back for people to listen to. Audio capture and playback devices typically feature a mesh cover on the capture head to prevent dust. However, excessive dust on the mesh can easily lead to inaccurate captured audio, necessitating dust removal.

[0003] Chinese patent number CN219780322U discloses an audio collection and external playback device, including a bottom cover, a functional shell fixedly installed on the top of the bottom cover, a collection head fixedly installed on the top of the functional shell, a speaker mesh fixedly installed on the top of the collection head, a motor housing fixedly installed on the left side of the outer wall of the collection head, and a cross bar fixedly installed in the inner cavity of the collection head.

[0004] The above-mentioned audio collection and external playback device, although the gear shaft is driven to rotate by the motor, and the rotating rod is then driven by the gear shaft and rotates accordingly, since a cleaning roller that fits the bottom of the speaker mesh is fixedly installed on the top of the rotating rod, the rotation of the cleaning roller can clean the speaker mesh, and at the same time, cooperate with the fan blades at the bottom of the rotating rod to generate wind force to blow away the dust on the speaker mesh, thereby improving the sound reception effect. However, since the dust mainly covers the upper part of the speaker mesh, and the cleaning roller cleans the lower part of the speaker mesh, the cleaning effect is average, and the dust blown away by the fan blades is still easy to fall back onto the speaker mesh, resulting in incomplete cleaning, so it is urgently needed to be improved.
