Sealed-type loudspeaker

Abstract

The invention relates to the field of loudspeakers and provides a sealed-type loudspeaker. The sealed-type loudspeaker comprises an inside PCB, an outside york and top protecting cover, an inside T iron, a voice coil, a magnet and a voice diaphragm; a copper ring for connection is arranged at the outermost ring of the voice diaphragm; the sealed-type loudspeaker is characterized in that adaptive spring washers are also arranged among the ring outside of the voice coil, the upside of the magnet and the voice diaphragm; the York is provided with a circle of bending part; the inner side of the bending part is adaptively fixed with the copper ring and the spring washers; the bottom of the york is open and is provided with a circle of inwards arranged backoff work-pieces; and the york is laminated, sealed and fixed through a round sealing plate. Rather than using glue and rivets for adhesion and bonding, the spring washers are such designed that the clamping buckles at the bending part arebutted with the voice diaphragm copper ring, assembling is facilitated, concentricity is guaranteed, and gluing processing is unnecessary in the whole assembling process. The sealed-type loudspeaker is simple, fast and convenient in processing technology, low in production cost, high in production efficiency and has no influence on the tone quality.

Description

technical field [0001] The invention relates to the field of speakers, in particular to a sealed speaker. Background technique [0002] The steps of the traditional loudspeaker assembly method: 1. Including the sound film assembly process, the sound film assembly process accurately glues the voice coil diaphragm through the voice coil fixing tool, the voice coil positioning tool, the sound film gluing tool and the crimping and gluing tool. 2. Magnetic circuit assembly process, the magnetic circuit assembly process fixes the magnetic steel, pole chip and bracket through the magnetic circuit gluing tool. 3. Bracket-diaphragm combination process, the bracket-diaphragm combination process glues the sound film semi-finished product and the magnetic circuit semi-finished product together, and performs welding, magnetization and testing to finally obtain the finished product. [0003] Among these headphone speaker products currently on the market, the speaker products are all bond...

AI Technical Summary

Problems solved by technology

Dispensing and cleaning are the most critical steps in the production process. Generally, the horn glue is A.B glue. In the dispensing process, there are problems such as uneven mixing, difficult control of glue output, hanging drops and other problems that lead to product quality.

It can be seen that the processing technology is relatively complicated, so the cost is not easy to control, and the production efficiency is low
