Description

Technical Field

[0001] The utility model belongs to the technical field of earphone speaker assembly, and in particular relates to a speaker sound film combined marking machine device. Background Art

[0002] In the existing technology, headphone speakers are dynamic speakers, which use the effect of the magnetic field on the current-carrying voice coil conductor to achieve electroacoustic transduction. The voice coil adhered to the diaphragm performs a cutting motion in the gap of the magnetic field, thereby driving the diaphragm to push the air to produce sound.

[0003] At present, in the field of loudspeaker manufacturing, when gluing and bonding the voice coil and diaphragm, the commonly used method is: the staff puts the voice coil and diaphragm into the corresponding jigs respectively, and then uses an ordinary glue coating machine to dot the center glue on the diaphragm, and then manually combines the jigs of the voice coil and diaphragm to bond the voice coil and diaphragm. After the glue dries, the sound membrane assembly is taken out; manual operation leads to low work efficiency and is prone to problems such as unstable wire clamping, which makes it difficult to ensure product quality. For this reason, a wire clamping mechanism of a fully automatic sound membrane combination marking machine is proposed. Therefore, a speaker sound membrane combination marking machine equipment is designed to change the above technical defects. Utility Model Content
