Description
technical field [0001] The invention relates to the technical field of voice coils, in particular to a voice coil that is easy to assemble and disassemble. Background technique [0002] Sound refers to sounds other than human language and music, including sounds from the natural environment, animals, machines and tools, and various sounds from human actions. In 1906, the American De Forest invented the vacuum triode, creating a precedent for human electroacoustic technology. Audio equipment is composed of audio source, control equipment, audio processor, power amplifier and speaker. The development of audio technology can be divided into four stages: tubes, transistors, integrated circuits, and field effect tubes. [0003] Voice coil (Voice Coil) is directly defined as a coil through which audio current passes. It is an important part of the vibration system of an electrodynamic speaker, and it can also be said to be the heart of the speaker. The performance of the voice ...
