Description

High-performance micro-flat magnetic horn Technical Field The utility model relates to the technical field of horns, in particular to a high-performance micro-flat magnetic horn. Background The flat magnetic horn of the existing structure is composed of an inner magnet and an outer magnet, the voice coil is placed above the inner magnet and the outer magnet, but the magnetic field outside the magnet cannot be effectively utilized, so that the magnet has a limit on the improvement of the sensitivity of the horn if the volume of the magnet is large. And the diaphragm is under high-power and under the condition of big amplitude, and the voice coil is more far away from magnet, and 0.6mm at least vibration space, when the voice coil upwards vibrates, receives the magnetic field effect of magnet less, and magnetic field efficiency is low, and loudspeaker performance is low. Disclosure of utility model The utility model aims to overcome the defects of low magnetic field efficiency and low horn performance in the prior art, and provides a high-performance micro-flat magnetic horn to solve the defects. In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: The utility model provides a high performance micro flat magnetic horn, includes shell and the protecgulum that has the sound hole, and the protecgulum lid closes on the shell, set up the diaphragm in the cavity that shell and protecgulum formed, the bottom bonding voice coil loudspeaker voice coil of diaphragm, install outer magnet in the shell and set up in outer magnet central interior magnet, the top bonding outer washer of outer magnet, the top bonding interior washer of interior magnet, the copper ring of diaphragm is arranged in between shell and the protecgulum, and the copper ring is located the platform of shell, and the top of outer magnet flushes with the platform of shell, and the copper ring is inside in to outer washer, and copper ring and outer washer are concentric. Further, the outer washer outer diameter is smaller than the copper ring inner diameter, the outer washer inner diameter is larger than the voice coil outer diameter, the outer washer inner diameter is larger than the outer magnet inner diameter, the inner washer outer diameter is smaller than the voice coil inner diameter, and the inner washer outer diameter is smaller than the inner magnet outer diameter. Further, the outer diameter of the outer washer is the same as that of the outer magnet, a sound outlet hole is formed in the center of the bottom of the outer shell, and the sound outlet hole penetrates through the inner magnet and the inner washer upwards. Further, the inner diameter of the outer magnet is larger than the outer diameter of the inner magnet, and the voice coil is positioned above the gap between the outer magnet and the inner magnet. Further, the thickness of the outer washer and the inner washer is more than 0.2 mm. Further, the bottom of the shell is embedded into a bottom washer, and a sound outlet hole is formed in the center of the bottom washer. Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects: 1. According to the utility model, the inner washer and the outer washer are correspondingly arranged above the inner magnet and the outer magnet, the copper ring is positioned on the platform of the shell, the top of the outer magnet is flush with the platform of the shell, the outer washer is arranged inside the copper ring, the copper ring and the outer washer are concentric, and the sizes of the inner magnet and the outer magnet and the inner washer are optimally designed and reasonably distributed through the copper ring of the diaphragm, so that the horn performance is improved, the thickness of the horn is not increased, and the application range is wider. 2.
