Multi-drive Ultra-thin Flat Panel Full-range Speaker
Application number: 2017208158652
The utility model discloses a multi-drive ultra-thin flat panel full-range loudspeaker, which includes a frame, a magnetic circuit system and a vibration system. The fame is provided with an accommodating cavity. The magnetic circuit system includes a U yoke, a magnet and a washer. The vibration system is composed of flat drum paper and voice coil. The magnet and the washer are bonded and superimposed, and they are all put inside the U yoke. The vibration system is composed of flat cone paper and voice coil. The magnetic circuit system have 2 pieces or more, and the voice coil also have 2 pieces or more.
The magnetic circuit system and the voice coil are bonded together to form a multi-voice-coil and multi-drive structure, and set in the accommodating cavity. The positive and negative poles of the voice coil are connected through external wiring to realize the parallel connection between multiple voice coils.
The utility model forms a multi-voice-coil and multi-drive structure by arranging multiple magnetic circuit systems and voice coils in a parallel structure in the accommodating cavity of the frame.
The setting of multiple voice coils is conducive to vibration balance, and the use of multiple drives can provide more powerful driving force for the diaphragm, improve efficiency, and maintain the height of the original speaker, effectively reducing the second and third distortion of the speaker, and make the frequency response curve smoother.
