Description

Technical Field

[0001] The utility model relates to the technical field of speaker cover, in particular to a speaker cover with a positioning structure. Background Art

[0002] A speaker, also known as a loudspeaker, is an electroacoustic transducer that converts electrical energy into sound energy through a certain physical effect. When different electronic energies are transmitted to the speaker's voice coil, the voice coil generates a kind of energy that interacts with the magnetic field of the magnet. This interaction causes the drum paper to vibrate. Because the electronic energy changes at any time, the speaker's voice coil will move forward or backward, so the speaker's drum paper will move with it. This action causes the density of the air to change and produce sound.

[0003] There is no positioning structure between the bracket and the cover of the existing speaker. Since the sizes of the bracket and the cover are relatively small, it is easy to have misalignment problems when the cover is assembled to the bracket. It is difficult for the cover to be accurately buckled onto the bracket, which makes assembly inconvenient and has a high assembly defect rate. Utility Model Content
