Description

Technical Field

[0001] The utility model relates to the field of speakers, and specifically to a speaker with a new structure. Background Art

[0002] A speaker, also known as a loudspeaker, is a conversion device that converts electrical energy into sound. When different electrical energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper cone to vibrate. Since the electrical energy changes at any time, the coil of the speaker will move forward or backward. Therefore, the paper cone of the speaker will move accordingly. As the paper cone moves, the density of the air changes, generating sound. With the continuous development of technology, consumers have higher and higher requirements for the sound quality and service life of speakers. Content of the Utility Model
