Description

Technical Field

[0001] The utility model relates to the technical field of speaker cones, in particular to a novel speaker cone. Background Art

[0002] The speaker cone, also known as the paper cone, is one of the important components of the speaker. Currently, most of the speaker cones on the market use paper cones, so many people also call the speaker cones paper cones. The working principle of the cone is: when an audio signal is input into the speaker, the voice coil vibrates in the magnetic field. Because the voice coil is fixed on the cone, the cone will vibrate along with it. The vibration of the cone forces the air to resonate, thereby making a sound. Therefore, different cone materials will produce different sound quality effects.

[0003] The Chinese utility model patent with publication number CN215222478U discloses a reinforced speaker cone for headphones, which relates to the field of speaker technology, including a cone skirt of an annular structure, a horn-shaped intermediate shell fixedly connected to the top of the cone skirt, a tail shell fixedly connected to the top of the horn-shaped intermediate shell, a first support rod, a second support rod, a third support rod and a fourth support rod respectively connected to the horn-shaped intermediate shell and the tail shell around, to reinforce the cone shell, reduce the vibration caused by sound, and extend the service life of the cone, and the horn-shaped intermediate shell is provided around There are several equidistantly distributed air vents in the middle shell and several equidistantly distributed heat dissipation holes on the top of the rear shell. In actual use, the heat generated in the entire sound basin can be quickly discharged with the help of the heat conduction holes in the earphone shell. A dustproof net is also fixedly connected just below the skirt of the sound basin to enhance the dustproof performance of the sound basin. However, there are multiple groups of clips, which are integrated with the shell and located at each end of the sound basin. If one or more groups are damaged, it will not only affect the connection with the internal shell of the earphone, but also be inconvenient to replace. The shell needs to be replaced as a whole, and the replacement cost is relatively high. Utility Model Content
