Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker production, in particular to a loudspeaker horn gluing mechanism. Background Art

[0002] A speaker is a device that converts electrical signal energy into sound energy and can radiate sound energy to a limited space (such as a room) or outdoor space. It is commonly known as a horn. The speaker is composed of a fixed permanent magnet, a coil and a conical paper cone. There are electric and electromagnetic types, and they are divided into built-in speakers and external speakers. The top of the speaker is usually covered with a layer of paper cone to assist the voice coil in sound radiation, which determines the playback performance of the speaker to a considerable extent. In order to improve the moisture-proof and waterproof performance of the paper cone and extend the life of the speaker, an oily glue is usually applied to the surface of the paper cone. It is a damping glue. The glue is usually applied directly to the paper cone through a nozzle. The dust attached to the paper cone easily deteriorates the adhesion between the glue and the paper cone, and it is easy to fall off in subsequent use. Therefore, a speaker speaker gluing mechanism is proposed to facilitate dust cleaning and improve the adhesion between the glue and the paper cone. Utility Model Content
