Bearing carrier of magnetic circuit assembly of bone conduction earphone and automatic assembly equipment thereof

Abstract

The invention discloses a carrier for bearing a magnetic circuit assembly of a bone conduction earphone and automatic assembly equipment of the magnetic circuit assembly of the bone conduction earphone. The magnetic circuit assembly comprises a magnetic conductive plate, a magnetizing plate and a magnetic conductive cover. An accommodating cavity is formed in one side of the magnetic conductive cover; a groove is formed in the upper end of the carrier, the shape of the groove is matched with the magnetic conductive plate and the magnetizing plate, the peripheral shape of the upper end of the carrier is matched with the containing cavity of the magnetic conductive cover, so that the magnetic conductive plate and the magnetizing plate are allowed to be sequentially stacked in the groove of the carrier, the magnetic conductive cover covers the periphery of the upper end of the carrier, and then a magnetic circuit assembly is formed. By means of the mode, the assembling errors among the magnetic conductive plate, the magnetizing plate and the can be reduced, and the assembling quality is improved.

Description

technical field [0001] The present application relates to the technical field of mechanical assembly, in particular to a carrier for carrying a magnetic circuit assembly of a bone conduction earphone and automatic assembly equipment for the magnetic circuit assembly of a bone conduction earphone. Background technique [0002] The magnetic circuit assembly of the bone conduction earphone is composed of a magnetic conducting plate, a magnetizing plate and a magnetic conducting cover. One side of the magnetic conducting cover is provided with an accommodating cavity, and the magnetic conducting plates and the magnetizing plates are sequentially stacked and accommodated in the accommodating cavity. [0003] In the prior art, when assembling the magnetic circuit assembly of the bone conduction earphone, the operator often manually places the magnetizing plate and the magnetic guiding plate in the accommodation cavity of the magnetic permeable cover in sequence, and glues the three...

Problems solved by technology

[0004] However, the inventors of the present application have found in the long-term research and development process that assembly by the method in the prior art may cause problems between the magnetically conductive plate and the magnetically charged plate, and between the two in the accommodating cavity of the magnetically permeable cover. The position is deviated and the assembly error is too large to meet the assembly requirements, thereby reducing the assembly quality of the magnetic circuit components
