Description

Technical Field

[0001] The utility model relates to the technical field of speaker structures, in particular to a connector and a speaker. Background Art

[0002] A speaker is a device that converts audio signals into sound. Generally speaking, it refers to a speaker box or subwoofer box with a built-in power amplifier that amplifies the audio signal and then plays it back through the speaker itself, making the sound louder.

[0003] However, the power cords and signal connection cables that match the existing speakers are cumbersome and the wiring is complicated.
