A loudspeaker structure

Abstract

The invention discloses a novel loudspeaker structure, including magnets, T irons, basin frame, washers, voice coils, elastic waves, dust caps, drum paper and spacers, the drum paper is provided with rings, and the spacers are located on the basin frame Below the outer edge, the magnet is located above the T iron, and a magnetic gap is formed between Wasser and the T iron, and the voice coil is arranged in the magnetic gap, and the voice coil includes a voice coil wire part and a voice coil tube part; A riveting groove is provided on the outer side of the washer, and the washer is riveted and fixed to the pot frame through the riveting groove. The voice coil is respectively bonded and fixed to the dust cap and the drum paper at the voice coil tube, and the dust cap and the drum paper are also bonded and fixed. The new loudspeaker provided by the present invention, by setting riveting groove points on the outer side of the washer, and riveting tightly with the pot frame, not only reduces the overall height of the speaker, but also ensures more space for the elastic wave to descend, and ensures the pot frame The firmness of the connection ensures the safety of vibration and drop after the speaker is packed, and meets the application requirements of small-diameter speakers.

Description

technical field [0001] The invention relates to the technical field of acoustics, in particular to a loudspeaker structure. Background technique [0002] A speaker is an acoustic component used to complete the connection between electrical signals and sound signals, and has been widely used in electronic terminals such as televisions and audio systems. With the rapid development of portable Wifi, Bluetooth speakers, and ultra-thin TVs, such electronic products gradually tend to be ultra-thin and optimized structural design, so a series of stricter requirements are put forward for the speakers, requiring small diameter and thickness. Thin, high power, high sensitivity with solid structure and smooth acoustic response curve. [0003] Traditionally, there are two ways to fix the washer and the pot frame of the speaker. Method one: punch out a bump on the washer and rivet it with the hole of the pot frame; however, the washer used in the small-diameter speaker Generally, they ...

AI Technical Summary

Problems solved by technology

The disadvantage of screw fixing is that the small-caliber speaker (speaker) washer screw hole is too small, and the punching needle is easy to break when the mold is punched when processing the bottom hole; in addition, the screw head takes up space, and the speaker is easy to hit the screw head when it is working. abnormal sound

Due to the difficulty of manufacturing additional screw holes in Huasi, the loss of punching needles is high, which also increases the manufacturing cost and processing cost virtually.
