Problems solved by technology

[0002] The existing loudspeaker voice coil is wound by a wire winding machine. Due to the thickness of the lead wire itself and the stress release after the voice coil is wound, the outer diameter of the wound voice coil cannot ensure the uniformity of size, resulting in the same batch of products. The sound quality of the speaker is quite different and cannot meet the needs of customers. It is necessary to shape the shape of the voice coil of the speaker to ensure the consistency of the size of the voice coil. The existing voice coil shaping mainly uses the physical expansion method. Into the voice coil, the shape of the voice coil is expanded and shaped, but the voice coil after physical expansion is easy to rebound, and the size of the voice coil cannot be guaranteed

Abstract

The invention belongs to the field of loudspeakers, and particularly relates to a tool and technology for shaping a loudspeaker voice coil. The tool for shaping the loudspeaker voice coil comprises a tool substrate and is characterized in that containing holes holding the loudspeaker voice coil are evenly formed in the tool substrate; the portion, at one side of each containing hole, of the tool substrate is provided with a lead groove used for holding one lead of the voice coil; the tool for shaping the loudspeaker voice coil further comprises ejection blocks matched with the containing holes; each ejection block comprises an ejection body and a holding portion; each ejection body and the corresponding holding portion are integrally arranged; the outer diameter of each ejection body is larger than the outer diameter of the voice coil and smaller than the inner diameter of each containing hole; the shaping technology of heating is conducted on the loudspeaker voice coil. According to the tool and technology for shaping the loudspeaker voice coil, the uniformity of the size of the voice coil can be effectively guaranteed and the stability of the quality of a loudspeaker is guaranteed.

Description

technical field [0001] The invention belongs to the field of loudspeakers, in particular to a shaping tool for the voice coil of the total loudspeaker and a technology for shaping the voice coil of the loudspeaker. Background technique [0002] The existing loudspeaker voice coil is wound by a wire winding machine. Due to the thickness of the lead wire itself and the stress release after the voice coil is wound, the outer diameter of the wound voice coil cannot ensure the uniformity of size, resulting in the same batch of products. The sound quality of the speaker is quite different and cannot meet the needs of customers. It is necessary to shape the shape of the voice coil of the speaker to ensure the consistency of the size of the voice coil. The existing voice coil shaping mainly uses the physical expansion method. Into the voice coil, the shape of the voice coil is expanded and shaped, but the voice coil after physical expansion is easy to rebound, and the size of the vo...
