Description

Technical Field

[0002] Audio refers to equipment and systems used to play music or other sounds. It usually consists of an audio source, a sound processor, a speaker and other related equipment. The performance of a sound system depends on many factors, including the quality of the audio source, the capabilities of the sound processor, the quality of the speaker, etc. The speaker is an important component of the operation. It has many internal components and requires close cooperation between the various components during assembly. The coil is generally installed between the annular magnet and the central iron core. An annular cavity is formed between the annular magnet and the central iron core. The lower part of the coil is located in the annular cavity and vibration is achieved through electromagnetic action. However, the requirements for assembly are relatively strict. Generally, the annular cavity formed between the annular magnet and the central iron core is relatively narrow. In this way, it is necessary to ensure that the annular cavity and the coil are coaxially distributed and cannot be offset in order to be successfully installed. For this reason, the entire structure is relatively strict during installation and matching, which makes the structural assembly flexibility very poor. Once the coil and the annular cavity are offset, it will be impossible to install.
