10 Inch Foam Edge Non Press Speaker Cone For Car Subwoofer

10 Inch foam Edge non press speaker cone For car subwoofer

In the speaker, after the voice coil is connected with the audio signal, it will produce strong vibration in the magnetic field. The voice coil is fixed on the paper cone. The vibration of the voice coil drives the vibration of the paper cone at the same time. The vibration of the paper cone forces the air to vibrate, thus producing sound. In order to achieve quite good pronunciation effect, the paper cone is generally made into a cone, and some paper cones of bass speakers are made into flat type, which is called flat speaker.

The working principle of the loudspeaker is: the permanent magnet generates a magnetic field in the annular air gap of the magnetic circuit through the yoke iron, and the voice coil connected to the speaker cone is inserted into the annular air gap. The permanent magnet is surrounded by the outer yoke, which can avoid The interference of the external stray magnetic field can in turn reduce the influence of the permanent magnet's magnetic field on the outside world. When the sound passes through the magnetic field in the form of current, the coil will vibrate at different frequencies due to the change of the current strength, and then drive the paper cone. Make sounds of different frequencies and strengths.
