Problems solved by technology

[0002] In the audio system, the voice coil will generate strong vibration in the magnetic field after the signal is connected. The voice coil is fixed on the paper cone, and the vibration of the voice coil drives the vibration of the paper cone. The paper cone used in the audio system currently on the market Various, although it can meet the basic pronunciation effect, there are still many defects. For example, with the high power of audio equipment in recent years, a sound system with high input resistance is required. When adding input signals to the sound system, When a current flows through the coil part of the voice coil, the coil part will generate heat due to its resistance, and this heat will be dissipated by the voice coil frame, the magnetic gap part, etc., but if an excessive input signal is applied to the audio system If there is no sufficient heat dissipation effect, it is easy to cause the coil to heat up and burn out. The traditional audio system paper cone must be installed with a dust cover, which leads to more connecting parts of the paper cone, and at the same time brings a burden on the assembly of the paper cone and increases manufacturing cost

Abstract

The invention relates to a paper cone for an audio system, which includes a membrane, a paper cone protection frame, a mounting flange and a diaphragm. The top of the mounting flange is uniformly equipped with a second return spring, and the second return spring is far away from the One end of the installation flange is installed with a paper cone protection frame, the top of the installation flange is provided with a cooling groove, and the inner center of the cooling groove is provided with a voice coil installation groove, and a sound coil is installed inside the voice coil installation groove. lock up. In the present invention, a drum is installed at the bottom of the diaphragm and a connecting groove is provided at the connection between the diaphragm and the voice coil. The drum just protects the voice coil and prevents dust from entering the magnetic gap. There is no need to install a dust cover, which saves parts. The assembly cost is reduced, and the bonding area is reduced, and the product quality is improved.
